Saving labor cost by printing 3d hand model

With the maturity of SLA light-curing 3D printing technology, some smart tablet manufacturers have begun to use 3D printers to include in their enterprise plans. The 3D printing tablet model is completely proofed according to the original shape of the plan, with low error. Compared with the traditional prototype, it saves the cost of proofing, shortens the manufacturing cycle of the prototype model, ensures the confidentiality of the product development planning scheme, and greatly improves the work efficiency and product development. According to the feedback from the manufacturer using the SLA 3D printing prototype of Harbin Industry, the business volume has increased rapidly and the labor cost has been saved by 40% since the use of the D printer prototype for about a year since March. Let’s see how 3D can help hand board manufacturers save 40% of labor costs!

The hand board is also called “model” and also called “first board” many years ago “. It is not only an important link to verify the feasibility of the product, but also an important link to find out the shortcomings of the product. Shortcomings. A more direct and effective method of shortcomings is to refer to the handboard to improve the shortcomings and deficiencies in the planning. The handboard can solve the above problems well. The handboard processing method has also evolved from manual to milling machines, engraving machines and CNC processing to today’s 3D printing manual models. Although many handboard manufacturers still Although they are used for CNC processing, the disadvantage of CNC has become a headache for the owners of many handicraft factories.

What are the problems of traditional hand board manufacturer CNC CNC machine tools in making hand board models?

1、 High dependence on labor: The complexity of CNC machine tool processing in traditional hand board manufacturers requires the proficiency of workers, while the labor cost in China has increased year by year in the past decade. In 1997, the salary of CNC CNC machine tool workers was 1000 yuan, and now the per capita salary is 6000-8000 yuan. Artificial masters have the right to speak. The younger generation of workers are unwilling to do this kind of work, and there is no successor to the technology. The workshop is noisy, the environment is poor, and there is a serious loss of automotive parts in the hand board industry.

2、 It is impossible to make a hand board with complex structure: some hand boards with very high accuracy, circuitous or hollow, and complex pure curved surface structures, CNC CNC machine tools are often unable to make them, even if they are reluctantly made, it will take a long time, and the cost is also very high. CNC machine tools with internal structure need to be separated and then assembled together. Many hand board manufacturers have actually lost their orders.

3、 Error prone: The accuracy standard of CNC machine tool itself causes some errors, especially when the operator is not skilled enough. This means that design defects will not be found before production, resulting in costly rework and time loss.

What are the advantages of using printers in 3D prototype factory?

1. Short production cycle, without cutting tools and molds: CAD digital model is directly processed and formed, with fast processing speed and short production cycle, without cutting tools and molds. CNC CNC machine tools usually need one week to deliver, while CNC machine tools usually need one week to print and one day to deliver. CNC CNC machine tools need to be on duty manually, while 3D printing does not need manual intervention. Basically, unattended production can be realized in the daytime or at night. The production efficiency is significantly improved and the cycle is shortened.

2. Reduce the cost of complex hand models: 3D printing technology can handle prototypes and molds with complex structures, or use traditional and mold. Industrial 3D uses printer SLA light curing technology to illuminate the surface of light curing materials (mainly photosensitive resin) with a specific intensity of laser focus, so as to make point to line and line to surface layer by layer. Ordinary hand boards or hand boards are relatively complex, and printing time and materials are not difficult. Resin 3D printing can be used to make some CNC machine tools that cannot manufacture precision structures, such as hollow-out, barb, hollow hand board model, etc.

3. There is no need for high education or senior experience. Simple and easy to use: Although 3D printing technology is very new, it is very simple to operate because most 3D printing processes are completed by computer intelligence. Users who use industrial 3D printers can start operation as long as they have received 3D training. It does not require high education or senior experience, and is easy to operate.

4. Environmental protection and health, high material utilization: traditional CNC machine tool workshop will produce a lot of dust and noise. In such a working environment, it is easy to cause anxiety and fatigue, which many people cannot bear. 3D printing technology, these problems do not exist. The sound produced by the industrial 3D printer when running is less than 10 decibels, which is smaller than the sound people usually communicate with. Its matching 3D printing material is also environmentally friendly and harmless. Unlike CNC CNC lathes, 3D printing hand boards are made by carving. Most of the materials are wasted, and the utilization rate is less than 35%. The utilization rate of 35% nylon 3D printing hand boards is more than 75%, which greatly reduces the waste cost of materials.

5. Customization accelerates product design innovation: 3D printers can quickly create a tangible physical model. The reduction of costs will inevitably lead to many industries being more willing to innovate in design, which in fact brings better experience to consumers of products. The demand for personalized customization will also be the continuous improvement of 3D with the popularization of printing technology.

Why do many tablet manufacturers choose 3D 3D printers?

A Brief Introduction To Carbon Fiber

A Brief Introduction To Carbon Fiber

There are many members of the carbon material family, including macro-scale coke, diamond, expanded graphite,carbon fiberand nanoscale carbon nanotubes, fullerenes and graphene. Among them, coke is mainly used in blast furnace ironmaking, mechanical casting, calcium carbide production, chemical fertilizer chemical gas production, etc. The real materials used for material preparation are expanded graphite, carbon fiber and various nano-carbon materials. These carbon materials either become part of composite materials as fillers, or themselves become a series of products that can be seen everywhere in production and life, such as sealing materials and building materials, through processes such as weaving and molding.
 
 
Carbon fiber is a fibrous carbon material that is lighter than aluminum, stronger than steel, thinner than human hair, and contains more than 90% carbon. It has excellent properties such as high impact strength, high tensile modulus, low density, high temperature resistance, ablation resistance, corrosion resistance, high electrical and thermal conductivity, low thermal expansion, self-lubrication and good biocompatibility. Most carbon fibers are composed of incomplete graphite crystals arranged along the fiber axis. They are hexagonal network layered accumulations composed of sp^2 hybridization. The crystallites composed of carbon atoms are the microstructural units of carbon fibers. The layer spacing is about 0.3360~0.3440mm, and the parallel layers are irregularly stacked, lacking three-dimensional orderly arrangement, and showing a turbulent layer structure. When carbon fiber is annealed at high temperature, it experiences a high temperature above 2500°C. When the carbon content is greater than 99%, the interlayer spacing decreases, indicating that the carbon atoms have transformed from the turbostratic structure to the three-dimensional ordered graphite structure, forming a graphite-like structure. These two types of fibers are divided into carbon fibers and graphite fibers in China and the United States according to different heat treatment temperatures, while in Japan and Europe, they are used to be collectively referred to as carbon fibers.
 
After carbon fiber was invented to replace filament in the early 18th century, it is widely used in textiles, materials, military, aerospace, atomic energy and other fields. Since carbon fiber began to develop on a large scale with technology, its output has grown at an average rate of more than 15% every year. By 1990, the world’s total carbon fiber production was 10,496t. In order to meet the needs of general industrial carbon fiber, its industry turned to large The tow direction is developed and the production scale is expanded from a hundred tons to a thousand tons.

The Method Of Inductive Pulse Interference In The Machine Tool Customer Service Network Of CNC Machine Tools

The Method Of Inductive Pulse Interference In The Machine Tool Customer Service Network Of Cnc Machine Tools

There are many ways to overcome grid pulse interference, the most fundamental way is to eliminate the source of interference. This requires the transformation of various electrical equipment. In the case of AC motors, freewheeling is difficult. In Siemens’ servo system, the alternating current is rectified into stagnant Power and then inverted. In this way, the motor is isolated from the grid, and the freewheeling diode can also be connected to the DC current. All kinds of machinery and equipment produced in West Germany now use industrial drive control for electric motors. This not only improves the efficiency of the motor and enhances the protection of the motor, but also avoids it and avoids their interference with the grid.
 
In our country, in order to eliminate the interference in the power grid, it is still difficult to achieve in a short period of time. Usually, the transformer isolation method is used to reduce the influence of the interference pulse on the numerical control system. The principle of this method is to use the characteristics of the inductive reactance of the transformer and the frequency of the signal. Because the frequency of the interference pulse is much higher than 50hz AC. So the transformer transmits much less power to it.
 
Capacitors can also be used to filter interference pulses. Large-capacity filter capacitors are generally installed in DC circuits. These capacitors are usually electrolytic capacitors. Compensate with a non-inductive capacitor. For example, Tangshan Cement Machinery Factory adopts this measure.
 
In addition to grid and electromagnetic interference, there are other factors that can cause downtime failures. For example, the electrical three defenses mentioned in electrical engineering, that is, the influence of humidity, salt spray, and mold should not be ignored. This situation has been encountered in Zhenjiang Hydraulic Parts Factory. The factory is located in the south of the Yangtze River, and the climate is humid. Although a humidifier is used, the circuit board is still corroded, causing downtime.

Reasons For The Application Of Carbon Fiber Composite Materials In Wind Turbine Blades

Wind Power is the focus of new energy technology in the 21st century. With the continuous improvement of wind power, for wind power, as the power of wind power is getting higher and higher, the blades of wind power are also getting bigger and bigger. The requirements for blades are also getting higher and higher. The lighter the material of the blade, the higher the strength and stiffness, the stronger the ability of the blade to resist loads. The bigger the blade is, the more and stronger the wind energy can be obtained, so the blade with light weight, high strength, high corrosion resistance and high designability has become the first choice.

In order to improve the utilization rate of wind energy, the single-unit capacity of wind turbines has been continuously expanded, and megawatt-level wind turbines have become the mainstream products in the wind power market. There is also the design of carbon fiber composite material extension blades to eliminate glass fiber materials, because they can have higher strength and specific stiffness.

That’s because the price of carbon fiber is ten times that of glass fiber, which makes the current wind power blades still mainly glass fiber. The length of the developed wind turbine blades has increased. The length of the carbon fiber blades developed by the German Nodex company for the 5MW wind turbine can reach 56M. The use of balsa wood and PVC sandwich materials in the interior greatly increases the structural rigidity and bearing capacity of the blades. Load capacity, and very power consumption reduces the mass of the blade, which provides favorable conditions for the development of the blade in the direction of long and light weight.

This is the reason why the blades on wind turbines are made of carbon fiber. As a domestic carbon fiber product manufacturer, Be-cu prototype has produced many carbon fiber products. Although it has not produced fan blades, common carbon fiber products have Production, welcome customers in need to come to consult. China Be-cu Prototype Material Technology Co., Ltd. is a company that has been in the field of carbon fiber product production and machining for many years.

Performance Analysis of Carbon Fiber Round Tube

Carbon fiber round tube is a typical product in carbon fiber applications. It has more advantages than metal round tube in terms of specific strength, specific modulus, corrosion resistance, fatigue resistance, etc., and has become an important structural material. It has excellent application prospects. In this article, we will specifically understand the performance advantages of carbon fiber round tubes.
 
Carbon fiber round tubes are mostly made of rolling process. From the current production of carbon fiber round tubes, the applications are mostly concentrated in round tubes within 100mm. The most prominent feature of carbon fiber composites in mechanical properties is anisotropy, and the mechanical properties in the fiber direction and the vertical fiber direction are completely different. Under the deformation, the carbon fiber tube firstly breaks the matrix, and then gradually begins to act as a fiber, and finally the fiber breaks.
 
Bending strength refers to the performance of structural materials under static bending load. Metal materials such as cold-rolled steel and titanium alloys do not have bending strength, and the bending strength of our commonly used T300 carbon fiber can reach 8500MPa. Generally, carbon fiber tubes of the same material, carbon fiber circular tubes with a diameter of more than 100mm and a diameter of less than 30mm can show good linear elasticity when the axis is stressed, and also show obvious brittleness when damaged.
 
Among the factors affecting the performance of carbon fiber round tubes, the diameter is not the direct factor, but the laying process and machining technology are the decisive factors. China Be-cu Prototype Material Technology Co., Ltd. is a powerful manufacturer of carbon fiber products. It has large hydraulic pipes, hot press forming tables, Cnc high-speed milling machines and other equipment. It also has a team of highly skilled, innovative, efficient and experienced engineers. The fiber-reinforced composite material technology development team insists on providing customers with high-quality carbon fiber products.

Cnc Machine Tool Factory

The rotary transformer of CNC machine tool factory is a common angular displacement measuring device on CNC machine tools. It has the characteristics of simple structure, sensitive action, reliable T operation, low requirements for environmental conditions, large amplitude of input H signal and strong anti-interference ability. Signal processing is more complicated, and resolvers are widely used in semi-closed-loop controlled CNC machine tools.
According to the functional relationship between output voltage and rotor angle, resolvers can be divided into the following j basic types:
① sine and cosine resolver. The excitation of single-phase AC Power supply is applied externally on the primary side, and the two output voltages of =ik r are related to the sine and cosine functions of the rotor angle respectively.
② Linear resolver. In a certain working angle range gate, the output voltage and the angle of rotation are linear functions.
③ Proportional resolver. It is similar to the sine and cosine resolver, with the addition of a device for adjusting and locking the rotor position in structure. In the system as a proportional component to adjust the voltage.
The structure of the rotary transformer in the CNC machine tool factory
The rotary transformer of the CNC machine tool factory consists of two parts, the stator and the rotor, as shown in Figure 4-16. Two distributed windings whose axes are perpendicular to each other in space, that is, two-pole two-phase windings, are embedded in the fixed and rotated iron core slots, respectively. CNC Machine Tool Factory S, S. and S: S. They are identical in structure for the purpose of setting the windings. R, wind and R, R are rotor windings, and their structures are exactly the same. The stator winding is the primary side of the transformer, the rotor is the secondary side of the transformer, the excitation voltage is connected to the primary side, and the frequency is usually /iOOHz, oOOHz, 1000Hz and 5000Hz. The mutual inductance between the stator and rotor windings of the CNC machine tool factory changes according to the sine and cosine laws of the rotor deflection angle. One signal changes in proportion to the sine of the rotor angle, and the other signal changes in proportion to the cosine of the rotor angle. The stator winding lead wire Directly to the terminal block, while the rotor windings are connected to the terminal block through slip rings and brushes.
The two-pole resolver commonly used in CNC machine tool factories has a pair of magnetic poles for the stator and rotor. In addition to this, there is a multi-pole resolver.

Development And Research Status Of Domestic PAN-based Carbon Fibers

Development And Research Status Of Domestic PAN-based Carbon Fibers

In order to meet the needs, in the late 1960s, my country and foreign countries began to develop polyacrylonitrile-based carbon fibers at the same time. In the face of export restrictions and strict technology blockades from Western countries, the older generation of scientific research workers has exerted the spirit of self-reliance. After hard work, they have developed carbon fiber products close to T-300. A carbon fiber with a strength close to 5.OGPa is obtained. The high-modulus Shiken fiber produced with foreign carbon fiber as raw material has just been successfully developed, and the high-strength medium-modulus carbon fiber is being developed.
 
The total capacity of domestic carbon fiber production is 850 tons/year. Compared with the advanced level of Okaji, domestic carbon fiber still has many shortcomings. The outstanding problems are the low strength of carbon fiber , poor uniformity and stability , There are many wools , single variety and high price , and the development level is nearly 20-30 years behind that of foreign developed countries.
 
This carbon fiber cannot be used for high-tech defense weapons that require high mechanical properties, and can only be used in ablation-resistant functional composite materials. The general-purpose carbon fiber whose performance index is suitable for the requirements of civil products is rarely used by domestic users because of the excessive unevenness and high price. This status quo greatly limits the upgrading of my country’s high-tech strategic weapon systems and the development of the national economy, which is extremely incommensurate with my country’s status as a major Power.
 
Our country’s scientific and technical personnel have accumulated a lot of perceptual knowledge on the technical issues affecting the principle and the quality and performance of carbon filaments; they have also done some work on the scientific issues of improving and improving the quality of the raw silk. However, those perceptual knowledge are hardly summarized and refined into key technical issues and key scientific issues for discussion and research in time. Even if some theoretical work has been done, it has been carried out in isolation, separation and one-sidedness, and most of it has been shelved in forgotten corners. Therefore, the research on the basic theory of carbon fiber is always weak, and the work on the raw silk is even more pitiful. In the past few years, very few theoretical articles have been published.

At the same time, the lower chamber of the cylinder 5 passes through the compressed narrow air, the piston rod 0006 drives the fork 7 to rise, and the position switch 9 is released to disconnect the relevant circuit to prevent the tool magazine, spindle, etc. from malfunctioning. During the rising process of the fork 7, the knife sleeve is driven to turn down 90 counterclockwise around the pin shaft 12. , so that the tool axis is parallel to the spindle axis.

Turn the pocket down 90. Afterwards, the shifting fork 7 E rises to the end point, press and hold the positioning Kaige 10． Send the H{ signal to make the manipulator grab the knife. The CNC machine tool can adjust the stroke of the fork through the screw 8, and the stroke of the fork determines the position of the tool axis relative to the spindle axis.

I. The action process of automatic tool change of CNC machine tools

  • ①The tool magazine moves the tool to be replaced to the position to be replaced according to the tool command in the program in advance.
  • ② According to the tool change command, the tool holder to be changed is turned 90 counterclockwise. , in the vertical downward position, the headstock rises to the tool change position, and the manipulator rotates 75. , the two grippers respectively grasp the tool in the spindle and the tool holder.
  • ③ After the automatic tool clamping mechanism in the spindle hole is released, the manipulator moves down to pull out the tool in the spindle and the tool holder.
  • ④When loosening the tool, blow out compressed air from the spindle hole, clear the spindle and the tool holder, and then the manipulator rotates 180 degrees. .
  • ⑤ The manipulator moves up, inserts the new tool into the spindle, and inserts the old tool into the tool holder.
  • ⑥ After the tool is loaded, the pull rod in the spindle hole moves up to clamp the tool, and the compressed air is turned off at the same time; then the manipulator rotates 75 degrees. Reset, the tool holder rotates up (clockwise) 900 to the horizontal position, and the tool change process is over.

2 CNC machine tool manipulator transmission process

Schematic diagram of the transmission structure of the manipulator of the CNC machine tool. The tool change manipulator of this machine tool is a double-arm rotary manipulator, which is the most commonly used in the T center. The pulling and inserting of the manipulator of the CNC machine tool is mostly completed by the oil cylinder. According to the structural requirements, CNC machine tools can adopt the structural form of “cylinder moving, piston fixed” or “piston moving, oil cylinder fixed”. The rotation of its arm is realized by the piston driving the rack and pinion transmission, and the stroke of the piston can ensure the different rotation angles of the mechanical arm.
