Stamping production quality requirements

Stamping parts in the process of production should pay attention to the following requirements, to ensure the production of product quality is guaranteed. one Demand for bending parts: 1) Bending shape should be symmetrical, must not be smaller than the minimum bending radius of the material allows the bending radius. 2) Curved short not easy forming, reason should be bend the edge of the straight part H> 2δ。 If the required H is very short, the need to set aside the appropriate to increase the allowance H, good bending after all increase of metal cutting. 3) Products before put the main inspection form to remove edge burr, after put into the inspection form first to check the accuracy of positioning hole core. two Time is the requirement of deep drawing parts: 1) The depth of the deep drawing parts appearance should be simple, symmetrical, shoulds not be too big. So that the drawing number, easy to take shape. 2) Deep drawing parts radius under the condition of without any increase in process. Otherwise will increase the drawing number and plastic work, increase mold number, and prone to waste and to improve the cost. A: stamping materials in how to choose
