Sheet metal processing is an important process for the forming of sheet metal products. The scope of sheet metal is relatively large, including traditional cutting and blanking, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new processes.
Cyanide zinc plating Because (CN) is highly toxic, environmental protection has put forward strict restrictions on the use of cyanide in galvanizing, constantly promoting the development of cyanide reduction and cyanide replacement electroplating solution system, requiring the use of low cyanide (micro cyanide) electroplating solution. After electroplating with this process, the product quality is good, especially the color plating, and the color remains good after passivation.
With the development of social economy and industrial progress, sheet metal parts are more and more widely used in our daily production and life. Automobiles, machine tools, and various household appliances all use a variety of sheet metal parts. Therefore, how to make sheet metal parts with good quality and beautiful appearance is particularly important.
Strengthen scientific research on sheet metal manufacturing process. In order to enhance the level of sheet metal technology, scientific research on sheet metal production is needed first, such as scientific research on various methods of structural mechanics in the whole process of sheet metal forming during sheet metal production, and then distinguish the deformation force and its deformation work, so as to more effectively select the loading capacity of machinery and equipment and the compressive strength of moulds, followed by scientific research on the change standard of prefabricated components in the whole process of sheet metal production, It can better select the appearance required by prefabricated components.
The main ways to realize the precision machining of parts are: using high-precision machining machine tools to process high-precision parts; Use error compensation technology to improve the machining accuracy of parts.
Consider the problem that the distance between the hole and the bending edge of sheet metal rivet screw or rivet nut is too small: during bending, there are bending deformation and tensile deformation at the same time. Holes and notches are too small from the bending edge, which will cause tensile deformation of holes and notches. Generally, there will be no bending deformation when the thickness away from the bending edge is 4.5 times of the material thickness.
1. Water Cooling Block Many techniques can be used to control the welding deformation of special welding workpieces. For example, in thin plate welding, the use of water-cooled blocks can take away the heat of the welded workpiece. The copper pipe is welded to the copper fixture by brazing or tin welding, and the circulating cooling is carried out through the water pipe to reduce the welding deformation.
Generally speaking, the basic equipment of sheet metal processing factory includes plate shears, CNC punches, laser plasma, water jet cutting machines, compound machines, bending machines and various auxiliary equipment, such as uncoilers, leveling machines, deburring machines, spot welding machines, etc. Metal plate processing is called sheet metal processing.
It can be seen from the specific activities of dust-proof design that most of the dust in the sheet metal structure cabinet comes from the extracted air in the cabinet, so a large amount of air should be avoided from flowing directly into the cabinet during the specific design.
When designing the sheet metal cabinet, we should first clarify the design performance of the sheet metal cabinet, and on this basis, use various new process design sketches, specify the size and structure, and determine the strength to make the technical parameters of the cabinet meet the design requirements.
With the development of social economy and industrial progress, custom sheet metal parts are more and more widely used in our daily production and life. Automobiles, machine tools, and various household appliances all use a variety of custom sheet metal parts. Therefore, how to make sheet metal parts with good quality and beautiful appearance is particularly important.
Customized sheet metal manufacturing The advantages of sheet metal manufacturing can be summarized as follows:high precision, high automation, fast speed, simple and convenient operation,high efficiency.
