Market research: CNC machine tool industry, technical personnel shortage

As a technology-intensive industries, China’s machine tool industry, especially high-end CNC machine tool industry talent seems to have been suffering from ‘anemia’. Solid theoretical knowledge, practical experience, wide range of knowledge, suitable for the technical person in charge of the enterprise or machine tool plant product development of CNC machine tools are particularly sought-after talent. However, the traditional industry talent shortage of frequent embarrassment. The loss of technical personnel, graduates ignore the embarrassment of traditional industries, so that the lack of numerical control machine tools and technical personnel has become increasingly prominent. NC plaque lack of talent With the growing demand for CNC machine tools, numerical control technology in various fields have been widely used, the demand for talent has gradually increased. However, there is a shortage of NC personnel in China drilling tapping machine, and it is urgent to develop a large number of technical personnel from all levels of research and development to maintenance.

\At present, the demand of NC personnel is mainly concentrated in the following enterprises and regions: In this case, 1, state-owned large and medium-sized enterprises, especially the current economic benefits of a better military industrial enterprises and major equipment manufacturing enterprises, military manufacturing industry is the main application of CNC technology object, Hangzhou power plant with a monthly salary of 6,000 yuan less than NC operators . In this case, 2, with the rapid development of the private economy, China’s coastal economically developed areas (such as Guangdong, Zhejiang, Jiangsu, Shandong), NC talent is in short supply, mainly in mold manufacturing enterprises and auto parts manufacturing enterprises. In this case, According to the relevant information, the current foreign CNC machinery and equipment rate has reached more than 85%, while China’s CNC machinery and equipment rate of less than 30% of the machinery manufacturing industry, new technologies, new technology applications, modern manufacturing molds, The industry of the watch industry, the hardware industry, the small and medium manufacturing industry, the computer drawing, the numerical control programming design, the mold design and the manufacture and so on, all broadly touches and uses to the numerical control technology, the talented person demand is really big. In this case, NC operator culture is uneven In this case, NC operator, mostly from the general machining, uneven quality of culture, in the application of CNC equipment, the idea of ​​applying common equipment processing, high-speed CNC cutting machine features, the choice of CNC tool, cutting the lack of scientific parameters , The merits of processing procedures and processing efficiency depends entirely on the level of the quality of operating workers, it can not maximize the processing efficiency of CNC equipment. In this case, Low-end solution to grasp the universal high-end In this case, ‘CNC operators and sweeping the same, there is no technical content.’ ‘This is a mechanical manufacturing enterprises in Chengdu, Zhang Yu, the views of the person in charge. He believes that now graduates of the NC professional students, and some posts with basic operations are not familiar with, and some products out of the defective products, and some high-handed, do not how long it will quit. ‘In fact, this reflects the school personnel training. ‘Chengdu Changzheng NC mechanical and electrical schools Vice President Mr girth welding machine. Wen said that at present the majority of the school NC professional training status quo is heavy heavy basic knowledge training, light high-precision professional development; re-school classroom learning, machine training, light business cooperation site Teaching; emphasis on knowledge to teach light professional ethics training. With a large number of NC students, the low-end jobs in the industry heat slowly cooling, these worries will be further exposed. In this case, ‘NC professional from abroad through the road, a simple CNC operator no future.’ ‘Southwest Jiaotong University Vocational and Technical Institute of CNC professional teacher Mr. Chen said, just as 10 years ago, like the computer professional, then, the school cultivates computer talent is in short supply, and now, the computer has become a general professional, employment and not easy.

From the global CNC industry development direction, the use of ordinary CNC machine tools more and more widely, together with the increasing degree of intelligent CNC machine tools, and gradually with self-diagnosis, adaptive control, logic analysis and judgment functions, in addition to a small amount High-precision manufacturing industry, the system’s intelligence to improve the requirements of the operator but in the lower. In this case, This can be seen, the reality, let CNC machine tool talent ‘anemia’ to alleviate, first of all to completely change the training methods to strengthen cooperation between enterprises and schools, market-oriented, training enterprises need talent, so that skills Talent to learn to use. At the same time, improve the assessment of highly skilled personnel and incentive mechanisms for talent to provide talent to display their talent space. We must not only create a glorious and important social environment for craftsmen and technical elites, but also expand the scope of training of skilled personnel, establish policies and institutional environment to promote the development of skilled personnel CNC busbar bending, and gradually form a training system and incentive mechanism .

High-precision punch for customers to create high-precision side of the product, to win market for customers to create favorable conditions. Appearance structure: fine, reasonable structure is to ensure the accuracy of the premise equipment. At present the market above the punch we see much more, you can feel the rough bed directly to the extent. Manufacturer size strength: the purchase of equipment manufacturers should also consider the scale of strength. Because some parts of the punch is made of special casting, once the manufacturer to stop production, the future maintenance will be made great trouble. After-sales service: the purchase of equipment after-sales service is also considered the focus of long-term use of equipment, will inevitably fail, after-sales service should be considered from three aspects: punch manufacturers reply and maintenance efficiency. Through the above we are about to buy high-speed punch are heart bottom, More questions, I can call the Division to resolve more doubts.

Pneumatic punching noise maintenance need to do what

Elimination of noise in the workplace Mechanical pneumatic presses commonly used crank slider transmission drilling tapping machine, in order to reduce the gap, the bearings should be required to install, with the appropriate assembly clearance. Due to movement and increase the gap, the bearings can be used at higher viscosity lubricants to increase the damping, air pressure can make the noise reduction. Improve the mold structure Inclined die instead of flat die, the use of knife-edge slope, so that the gradual separation of sheet metal, which delayed the punching time, can play a certain noise reduction effect. The noise reduction is related to the shear angle, and the larger the shear angle is, the longer the punching time is, and the lower the noise level is, the better the shear angle is 8 ° ~ 10 °. Improve the machine structure The series of open-type double-column fixed table presses and series open double-Zhu tilting press to friction clutch.

Pneumatic punching system with multi-purpose transmission gears, pneumatic presses will start gear meshing sound, if the use of helical or herringbone gear drive drilling equipment manufacturers, can basically eliminate this friction noise. As far as possible with or without high-pressure compressed air blowing unloading pieces drill machine buy online, it is recommended to use simple robot or tilting the bed more than 15 °, so that pieces automatically fall into the parts box. Set sound-absorbing, vibration-damping device The pneumatic punch press wheel and its transmission system plus enclosures closed up, can significantly reduce the transmission part of the noise. For high power, high noise motor should also be configured with partial acoustic enclosures or enclosed acoustic enclosures. In the lower part of the pneumatic press slide or outside the mold work area, install protective fence or noise enclosures. If the noise in the mold outside the cover, then paste the inner wall of the sound-absorbing material, noise reduction effect is more significant. Noise of personal protection With protective cotton, cotton, rubber, rubber earplugs, plastic ear plugs to plug the ears to prevent or reduce the noise on the human hearing hazards. Can also wear soundproof earmuffs, you can put the entire helix and outer ear canopy cover, not only sound effects, and no abnormal feeling. If the combination of earplugs and earmuffs, the noise better.

Pneumatic Press Problem – Cylinder

Pneumatic punch on the cylinder when the failure occurred in the pneumatic punch cylinder surface coating or spraying 3D CNC Drilling Machine. When the pressure punch cylinder with a large area of ​​?? steam leakage, the gap in the 0.50mm or so, in order to reduce the amount of work scratching can be coated with the process. With the pneumatic press cylinder cylinder anode custom drilling machine, coated with a cathode, in the cylinder on the surface of repeated brushing electrolytic solution, the coating thickness to be based on the size of the cylinder joint surface clearance, the coating type according to the cylinder material and repair Scraping the process may be.

 

Spraying is the use of special high-temperature flame gun metal powder heated to melt or reached plastic state after the jet on the surface of the treated cylinder to form a layer with the required performance coating method. It is characterized by simple equipment, easy to operate coating firm laser cutting machine, after spraying the cylinder temperature is only 70 ℃ -80 ℃ will not cause deformation of the cylinder, but also access to heat, wear and corrosion resistance of the coating. Note that in the Tudu and spraying before the cylinder surface to be polished, degreasing, nap, Tu Tu and spraying after the coating to scratch, to ensure that the combination of pressure punch tight. The method of determining the equilibrium point of the press: 1, the slider stops at the bottom dead center 2, the balancer pressure completely excluded 3, scale set up and zero 4, record the air pressure of the balancer under the scale readings The balance point of the punch: record the relationship between the slider position change and the air pressure of the balancer, and determine the balancer air pressure set value by the change of the punch displacement curve.

What is the role of Clutch Brake in Precision Punching

Precision punch press brake device installed by the role of precision brake press brake by the trachea, brake cylinder, valve chamber, brake piston, brake discs, including precision punching brake cylinder and brake cylinder valve The cavity of the valve disc is connected with the brake piston, the brake cylinder is connected with the brake disc through the spring, and the brake disc is connected with the brake friction disc. One end of the precision punching drive shaft is interposed between the clutch piston and the clutch friction plate through the clutch holder and the other end is interposed between the brake disc and the brake friction disc through the brake cage.

The middle part of the drive shaft is respectively provided with a front spacer, a middle spacer, a back spacer and an unloading sleeve, the front spacer is connected with the brake cage, and the rear spacer is connected with the clutch cage Drilling Machine for Sieve Plate. Punch is equipped with a clutch brake is used for real-time braking on the punch to ensure the safe and accident-prone, the traditional punch used mechanical clutch, noise, high wear and poor manufacturing stability, for this in the precision punch on both With a pneumatic clutch brake, as a professional manufacturer of punch in this detailed solution about the structure and characteristics of pneumatic clutch brake: Precision punching clutch brake using split structure, by the clutch device and brake device composed of two parts.

The precision punch press and clutch device is composed of a clutch cylinder, a clutch cylinder, a valve cavity, a clutch piston and a clutch brake disc. The clutch air pipe is communicated with the valve cavity of the clutch cylinder, and the clutch plate in the valve cavity is crimped onto the clutch piston Marking on Metals, The clutch piston and clutch friction plate crimp, clutch friction plate and precision punch flywheel. Precision Punch Clutch Brake with split structure, the clutch device and brake device is located at the ends of the drive shaft, so the entire precision punch force balance; when both are not through the compressed air, the brake relies on spring force to brake When the precision punch press transmission system is running, the brake cylinder must be ventilated to overcome the spring force to make the brake off, and then the clutch cylinder ventilation, pushing the piston to the precision punching machine Clutch, so as to drive the transmission system, on the contrary, when the air, you must first exhaust the clutch cylinder, the clutch disengaged Drilling Machine for Plate, and then the exhaust brake cylinder, the brake combination. Precision press brake clutch through the valve to promote the piston movement, the movement is very smooth, low operating noise, from the fundamental to ensure the safe and efficient production of stamping.

Precautions when installing precision presses

1) In the mold before the punch, the use of Whetstone to the underside and the top of the burr worn off CNC Busbar Punching Machine, with a cloth to clean up the waste. If there is burr or rubbish on the upper and lower surfaces of the mold, it will cause the burr tolerance of the die. 2) Punch Adjust the slide stroke to the satisfactory position to press the upper mold, must ensure that the mold handle or the mold frame on the plane of the bottom of the slider clever fit, the next pressure plate screw gently pressed. And then adjust the slide up the punch, remove the center of the silicon steel sheet.

Loosen the lower mold plate screw, adjust the slider downward until the punch enters the die 3 ~ 4mm, press the lower mold plate screw drill machine. Punch a new punch punch punch must be into the mold 3 ~ 4mm, otherwise, there must be punch die or concave die burst. 3) take off the slider to the top dead center position, adjust the punch rod to stop the screw, to tighten properly, and then idly a few times to observe the mold and punch the work of the agency is unusual. If there is no abnormal situation, you can start the production.

4) Before punching, it should be confirmed that the cutting edge of the die is sharp and there is no chipping on the cutting edge of the die. If there is collapse or missing angle, please rub the first knife blade. 5) before the mold should be in the upper and lower mold between the pad into a silicon steel sheet, defensive due to handling the process of bumps injury angle Opening Machine.
