Understand common problems aluminum stamping production
Aluminum stamping parts are widely used in different fields because of its surface oxidation can be often as appearance to make, but our stamping manufacturer in production will meet all kinds of problems, the author discusses several problems together with everybody today: aluminum stampings in blanking, punching and trimming when too much burr, deformation, surface scratches, as well as the discharge process is how to produce?
1, the cause of excessive aluminum stamping burr: intensive clearance is not appropriate, knife edge wear, the guidance precision is poor, where intensive heart, etc. ;
2, the pitch of stamping deformation may be too small, pressure plate and the concave model face is not reasonable, and greatly gap causes;
3, parts surface is scratch: eliminate the raw material on the surface of the original state, the causes of general shear process is defined as the drag operation, the blank scratches, etc. ;
4, size does not conform to the usually production not accurate, or loose or damage location positioning device to beat;
5, leakage process human factors is very large, or mould punch broken have been damaged no rush in place of;
