Stamping parts

Stamping partsIs efficient production methods, the use of compound die, especially the multi-station progressive die, it can be finished in a pressure on multichannel stamping process, realize the pick-up uncoiling, leveling, cutting to the forming and finishing of automatic production.High production efficiency, good working conditions, low production cost, general can produce hundreds of pieces per minute.Stamping with sheet metal surface and internal performance of stamping has great influence on the quality of the finished product, request stamping material thickness precision, uniform;Smooth surface, no spots, no scar, no scratch, no surface crack, etc.;Yield strength evenly, no obvious directivity;High uniform elongation;Showed low;Low strain hardening.

Punch edge end fix the bevel or arc.This is an effective way to slow down the blanking force.Slow down the blanking force, can reduce the tensile force of the concave side material, thus suppressing stamping double material and torsion effect.Daily mold production, should pay attention to maintenance of convex and concave die cutting edge sharpness.When cutting blade wear, material by the tensile stress will increase, and stamping parts produced material, distortion tends to increase.

Stamping is mainly classified by technology, can be divided into separation process and forming process two kinds big.Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section.
