Deep Drawn Stamping Copper Sleeve For Mechanical Keyboard Keys

Deep drawn stamping Copper sleeve for mechanical keyboard keys

Should try to avoid the design depth of the flange and the large tensile), because such artifacts need more drawing number. Workpieces, for example, not size and lower size difference is too big, do not conform to the requirements of the drawing process, want to let it compound requirements, it can be divided into two parts, respectively, to carry on the processing and manufacturing, after connect.

1) If the workpiece cavity is not deep, but the flange diameter is large, manufacturing difficulty is big, middle annealing treatment is needed. If the flange diameter decreases, can need not intermediate annealing.

2) Artifacts of the flange outer profile best contour shape is similar to that of a deep drawing part, if the width of the flange, not only hard to stretch, need to add the process, still need to broaden the trimming allowance, increase of metal consumption.
