AbstractPotentiometer applications in daily life is very extensive, especially in electronic devices. It is an adjustable electronic components, by a resistor body and a rotating or sliding system components, main and diverted from the partial pressure, it works with the variable resistors are quite close, but also more multi-species. Recently, multi-position progressive die stamping more and more important in the mold, this mold is the design of graduate potentiometer lug stamping process and die design, primarily through the use of multi-position progressive die to complete, will effectively improve the stamping pieces of quality and production efficiency. In this design drawing parts in the graph and analyze the potential wiring film forming process features, including the use of the size of the workpiece calculated expansion plan, part of the process analysis, the blanking force and drawing force calculation, mold design of the difficulties, such as lugs bending and trimming, set the layout for progressive die and mold the overall program structure and automatic feeding device. The progressive die with blanking, drawing, shaping, expansion, etc. 7 station. Details of the punch and die, fixed plate, unloading equipment and other parts of the design and manufacture of presses and related auxiliary equipment used. It illustrates the working process of the mold, the forming coordination of movements, as well as punch and die inserts assembly space, and to develop typical machining process.
