Now the process of sheet metal processing is relatively rapid, the raw material is very important for the equipment, so the raw material will have more stringent requirements, because the defects of the raw materials will directly affect the quality of the stamping parts, so the selection of raw materials should be careful. Our understanding of some raw materials will increase our quality of sheet metal processing.
The importance of raw material for sheet metal processing
Sheet metal processing refers to the general process of punching, cutting and bending. Sheet metal processing is also the processing of sheet metal. The common raw materials in sheet metal processing are steel, aluminum, iron and other metal materials.
The deformation defects of raw materials are mainly caused by unreasonable process or illegal operation in the process of steel rolling, storage and transportation, hoisting and so on. For example, the steel plate material has more serious uneven deformation defects. In the use of Longmen shearing, the deformation steel plate can not lose the scissors scissors on the scissors worktable. The shearing action can not make the T process a great difficulty. Due to local deformation defects such as uneven, bending and twisting, it directly affects the accuracy and quality of lofting, marking and blanking, especially the blanking process.
In addition to the shape and deformation of steel, the precision and quality of the material will be affected, and the processing difficulty of the material will be affected. The stress in the material will be larger and the stress will be released further after the material, and the deformation will be further expanded. The damage caused by the deformation is also greater. For example, there are problems in the process or equipment during the rolling process of the raw material of steel plate, which causes the stress and deformation of the steel plate. In the process of gas cutting, the process heating and the original stress are further released. The stress and deformation of the raw material will often produce greater stress and deformation, which causes great difficulty and influence to the process forming or the group welding procedure in the future. .
Automation and digital control cutting machines not only improve production efficiency, ensure product quality, but also replace the work of lofting and scribing. For example: CNC shearing machine, CNC punching machine and other functions are more sound and reasonable; CNC oxyacetylene cutting machine, laser cutting machine and other wide applications have replaced manual cutting technology, to improve the efficiency of production and guarantee the quality of the product. The mechanical laying equipment has applied high and sophisticated technology, such as high pressure water cutting technology (the pressure of cutting water beam is more than 400MPa), and can cut steel plate and large rod with a thickness of more than 100mm.
