Song Yongzheng, an expert and consultant of the China Sheet Metal Association, made a detailed discussion of sheet metal processing from several aspects such as sheet metal equipment technology, sheet metal process technology, and sheet metal networking. Sheet metal processing technology is divided into two aspects. One is sheet metal equipment. Technology, the second is sheet metal technology. Sheet metal equipment serves sheet metal technology. Modern sheet metal equipment mainly includes: CNC turret punches, CNC hydraulic shears, CNC bending machines, CNC laser cutting machines , CNC laser welding machines and flexible sheet manufacturing systems. Sheet metal technology serves for the production of sheet metal parts, which is a direct embodiment of sheet metal technology. Laser processing mainly includes: cutting, welding, heat treatment, marking, engraving, etc. Laser cutting accounts for about 60%, laser welding accounts for about 20%, and laser heat treatment and cladding account for about 15%. Laser cutting has a narrow slit, high cutting speed, high precision, and low noise, which is suitable for CNC or computer numerical control. High-power CO2 lasers are mainly used, and fiber lasers have been used in recent years. Suitable for cutting metal and non-metal materials. The maximum cutting speed can reach 50m / min, the positioning accuracy is 0.01mm / 500mm; the thickness of the cutting plate is 1mm and the diameter of 3mm small holes, 100 per minute, the diameter error is ≤50μm; The future development trend is high-speed and high-precision, cutting thick plates and large pieces, three-dimensional cutting, unmanned automation, and small footprint. Sheet metal networking is a virtual simulation system for the entire process from drawing to machining. It can simulate the machining process, inspect the machining, reduce preparation before machining, and can manage all engineering data to realize the network of designing and processing sheet metal parts. Faster, faster and more rational, is a new processing concept to improve production efficiency, and also the main development direction of sheet metal processing technology. Liu Yongsheng, an industry researcher of the China Forging Association, gave a speech titled "Analysis of the Operation Situation of the Sheet Metal Industry at 杏鑫平台 and Abroad". He reviewed the comparison of the metal forming industry surveys in China and the United States in 2013 with various data, and compared the 2014 sheet metal industry The semi-annual operation and forecast for the second half of the year are explained. In 2013, the comparison of the sales revenue of the U.S. metal forming industry with that of China showed that the proportion of U.S. metal forming companies with sales below $ 5 million was 11%, China was 22.86%, and the proportion of Chinese sheet metal industry enterprises was 36.11%; sales In the US $ 20 million to $ 50 million, the proportion of companies in the US metal forming industry is 38%, that of China is 10%, and that of China's sheet metal industry is 5.56%. From these two data, we can see that the gap between Chinese metal forming companies, especially the sheet metal industry, and the United States is still very large. There is still a long way to go. Enterprises need continuous efforts to improve themselves and strengthen themselves. Foreign sheet metal companies have specialized and precise product positioning, high customer levels, product development capabilities, scientific and reasonable plant layout, and smooth on-site logistics, which is not only conducive to improving production efficiency, reducing production costs, but also adjusting hygiene and protecting employees' health and health. Safety. Chinese sheet metal companies should learn the advantages of foreign sheet metal companies and become stronger as soon as possible.

Dongfeng Automobile Mould Co., Ltd.'s gages have always been the bottleneck in the manufacture of gages during the manufacturing process. It has a long processing cycle and high accuracy requirements. The manufacturing, testing, installation, and debugging of the gage section gauges account for almost 1/2 of the manufacturing cycle of the gage. In order to meet the market's requirements for the delivery time of the gage, it is necessary to break through the traditional manufacturing process of the gage section gauge and adopt new processes and new equipment. In response to this problem, the company improved the laser cutting machine from software programming, process parameters, cutting worktables, etc., and finally determined the machining allowance of the blank through a process test to meet the minimum machining allowance of the laser cutting to make the hair blank Minimize size. Improving the laser cutting technology can greatly shorten the processing cycle of the gage section gauge, reduce the number of processing steps, and reduce the processing cost. Laser hardening is the rapid heating of a metal surface by a laser beam with sufficient power density to strengthen its surface. It has the advantages of fast thermal cycling and no deformation of the quenched parts; fine structure of the quenched layer, good hardness and wear resistance, and good toughness and matching; the effective depth of the hardened layer is 0.5 to 0.7mm; almost does not damage the surface roughness; accuracy and accuracy Good controllability, laser quenching does not crack; laser quenching is clean and efficient, and does not require cooling media such as water or oil. The future research direction of Dongfeng Automobile Mould Company is to change the problems of unstable and slow speed of the traditional large-scale manual hardening process of the mold; make the hardening process of the mold more parameterized; extend the service life of the mold.
