Electronic metal stamping parts production quality requirements

by:Fortuna     2021-02-13
Electronic metal stamping parts production quality requirements in the electronic hardware stamping parts factory for stamping production quality requirement is very strict. So we must strictly control the shape of the stamping size: first is the requirement of 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) The bending with hole, in order to avoid deformation of the hole. Second 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: metal stamping parts in stamping process should pay attention to what
