Sheet metal processing
Briefly describe the hazards of raw material deformation, Sheet metal processing in addition to the hazards in the process of processing, in fact, there will be some hazards in many raw material selection. The deformation defects of sheet metal processing raw materials are mainly caused by unreasonable workmanship or illegal operation in the process of steel rolling, storage and transportation, and hoisting. Due to unevenness, bending, twisting, etc.Deformation defects directly affect the accuracy and quality of lofting, numbering and blanking, especially the blanking process. In addition to the shape deformation defects of steel will affect the lofting, material accuracy and quality, and affect the processing difficulty of blanking, but also due to the large internal stress of the material, the internal stress will be further released after blanking, resulting in further expansion of deformation. The damage caused by sheet metal processing deformation defects is correspondingly greater.
