If the stamping scratches?

Stamping processing is the use of conventional or special equipment of the power, the deformation of sheet metal in the mould is directly force and deformation, thereby gaining a certain shape, size and performance of the production technology of product parts. Sheet metal, stamping mould and equipment is processing of the three elements. Metal stamping parts processing is a metal cold deformation processing method. So, called cold stamping or sheet metal stamping, stamping for short. It is plastic metal processing ( Or pressure processing) One of the main methods, also belongs to the material molding engineering technology. Used by stamping mold known as the stamping die, die for short. Die is the material ( Metal or nonmetal) Batch processing into salt pieces of special tools required. Is of vital importance to the die in stamping, did not conform to the requirements of punching die, stamping production batch is difficult; No advanced punching die, stamping process of advanced cannot achieve. Stamping process and die, stamping equipment and materials to form the three elements of stamping processing, can only draw stamping them together. Dongguan coiled material adverse phenomenon common metal stamping parts mainly has the following several aspects: 1, the steel plate surface or a foreign body inside, with foreign body peeling, coil scar in the same state; 2, scratches, The roll surface or different material) , the edges ( 20～30mm） Due to the stress non-uniform deformation or crushed, coil edges broken; 3, due to sliding roller, foreign bodies in the coil back pressure after entering the bulge ( Foreign bodies fall disappear) ； 4, margin irregular broken, beyond material adverse beyond the rules; 5, roller marks ( Foreign body attached on the roll) Influence, caused by foreign body surface depth. Practical use, the dongguan metal stamping parts with scratch ( The roll surface or different material) And after the foreign body into the coil on the back of the pressure out of the bulge ( Foreign bodies fall disappear) And roll marks ( Foreign body attached on the roll) My most favorite is the use of the problems. The solution is simple, foreign body disappear is the direct approach. Hardware products factory in the previous: about stamping parts of the surface roughness
