What are the matters needing attention in sheet metal processing industry and sheet metal processing flow?
With the development and progress of the society, the application of the sheet metal processing technology is more and more proficient. It is obvious that the sheet metal processing is a key technology that the sheet metal technical staff need to focus on. It is also the most important process in the forming of the sheet metal products. China's Shenzhen sheet metal processing industry has developed relatively late compared with foreign countries. Many small enterprises and small workshops have appeared, and many enterprises are relatively backward in sheet metal processing and production technology, and the production management is not perfect, so there are many hidden dangers in the sheet metal processing places. If we want to ensure the safety of the staff concerned, it is very necessary to know some safety matters in sheet metal processing. In the process of sheet metal processing, there is a hidden danger in the process of sheet metal processing. On the one hand, the relevant leaders of the enterprise need to perfect the working situation of the operator as far as possible, and make the relevant principles of safety operation; on the other hand, it also needs the operator to keep a cautious and serious attitude in the process of sheet metal processing. This will help improve staff safety awareness, reduce the risk coefficient of sheet metal processing, and promote the better development of sheet metal processing industry.
The process flow of sheet metal processing:
1. Blanking. After the drawings have been made, the blanking mode is decided according to the expansion plan, batch gap and technical requirements, including laser, CNC punching machine, shearing plate, mould, etc.
Two, bending, pressing riveting, flanging tapping, spot welding, convex hull. Sometimes the nut or stud should be pressed after bending the one or two way. If there is a mold to make a convex bag, it should be processed first to avoid interference before the other process is first processed, and the processing that needs can not be realized.
Three. Surface treatment. The surface treatment of the workpiece should be treated after the process of bending and pressing riveting. The surface treatment of different plates is different. After the cold plate processing, the general surface treatment methods are electroplating, electrostatic powder spraying, phosphating treatment before spraying, and then spraying after the phosphating treatment.
Four. Test. The quality of sheet metal parts, in addition to strict control in the production process, is the quality inspection that needs independent production. The first is to strictly check the size according to the drawing, two is to strictly check the surface quality, to repair or dispose of the incompatible persons, the appearance can not be scratched, the color difference, corrosion resistance and attachment force after spraying are carried out. Test.
Experts believe that the risk factor of sheet metal processing operation is very high, in the construction must concentrate on the thought and wear gloves and other protective items, not fatigue operation, nor can chat or smoke operation. Tools, fixtures and other work pieces can not be burglarproof on the gearbox. Moreover, the residual iron filings in the machine should be used with special hooks and not directly pulled by hand. The iron scraps spilled will easily hurt people. Sheet metal processing is a direct way to include the traditional blanking, cutting, bending, and so on, as well as those process parameters, so it will also include a variety of cold stamping die structures and some process parameters. The working principles of various equipment and the manipulation methods can also be included. Including such a new stamping technology and new technology, the processing of the metal sheet on the parts is called sheet metal processing. It is very easy to watch the important procedures of such sheet metal processing, and be able to pay much attention to the special style of the sheet metal processing.
