In the numerical control sheet metal process, the material can be divided into the way of punching, counting, cutting, laser cutting, and wind cutting, because the processing technology of the different processing methods of the sheet metal processing in Shenzhen is also different when the material is different. The way of the sheet metal blind talk is mainly the number of blanking and laser cutting. In the numerical control sheet metal process, the number of blanking is the main use of CNC punching machine for processing, and the thickness of the thickness of the plate used should be cold rolling plate, hot rolled plate less than or 3 millimeters of winter rain, the aluminum plate should be less than or equal to 4 mm, and stainless steel should be less than or equal to 2 millimeters. Laser cutting is a laser cutting process and the thickness of the plate thickness processing range is, the cold rolling plate and hot rolled plate are less than 20 millimeters and less than 10 millimeters. The advantage of laser cutting is that the thickness of the plate is large and the shape speed of the cutting workpiece is faster, and the machining is also very flexible. It is impossible to manufacture mesh parts by using this method because the cost of processing is too high.
The effect of stainless steel sheet metal processing is, at present, mainly:
Surface texture effect: it is through forging, marking, grinding and corrosion and other processes, processing texture effect on its surface.
Polishing effect: using abrasive materials to smooth the stainless steel surface, so as to achieve certain effect.
Sandblasting effect: it is through abrasive and so on, so that its surface shows a slightly rough sand effect.
Surface etching and etching: the use of chemical acid to corrosion, to get a mottled and vicissitudes of the decorative effect.
Surface forging effect: it is to forge on its surface, so as to form punctate texture, so that it has a sense of stacking, and then has decorative effect.
钣金车间加工部件的加工步骤为产品前期试验产品加工试制和产品批量的生产。在产品加工试制步骤时应及时与顾客沟通联系得到相应加工的评价之后在进行产品批量的生产。 激光打孔技术是激光材料加工技术中最早实现实用化的激光技术。钣金加工车间中激光打孔一般采用的是脉冲激光能量密度较高时间较短。特别适用于加工具有一定家督和材料较薄的小孔，还适合加工强度硬度较高或较脆较软材料的零件上的深小孔和微小孔。 激光可实现燃气轮机的燃烧器部件打孔加工打孔效果可实现三维方向数量可达到上千个。可打孔的材料包括不锈钢镍铬铁合金和哈斯特洛伊基合金。激光打孔技术不受材料的力学性能影响实现自动化比较容易。
The processing steps of the parts in the sheet metal workshop are pre production, trial production, and batch production. In the process of trial production, it is necessary to communicate with customers in a timely manner and get the product batch after production. Laser drilling technology is the earliest practical laser technology in laser material processing technology. Laser drilling in sheet metal workshops is usually based on pulsed laser with high energy density and short time. It is especially suitable for processing small holes with a certain family governor and thin material, and is also suitable for small holes and small holes on parts with higher hardness or more brittle and soft materials. The laser can realize the punching and drilling effect of the burner parts of the gas turbine, and the number of three dimensional directions can reach thousands. Perforated materials include stainless steel nickel chromium iron alloy and Haas Tero Edge alloy. Laser drilling technology is not easy to automate due to the mechanical properties of materials.
