Abstract
This article introduced the superposable die design processing method, processes the mold spare part meets the specification completely. Falls the material punching die, its principle of work is as follows, direct or asked that meets fixes on top die's composition mold's top die, it joins through the die shank and the punch press slide. Fixed has composed mold's stamping die on stamping die's zero, and fixed using the clamp on punch press's work table. The top die and the stamping die through lead, lead the guidance. When work, the strip material closes right up against keeps off the material to feed in the localization, when top die along with slide drop, the ex-denning suppresses the sheet first, then raised flushes falls the concave above material to obtain the work piece. By now the work piece card with went against hearing of the block in the plunger, the waste material also tight band on the plunger. When the top die rises again, the work piece by goes against the block to go against depending on the roof taking advantage of spring's tension from lower die Dongkou; Simultaneously bind rounds on the plunger the waste material, by unloads the yard lumber to download depending on spring's tension, takes the work piece again, hence completes entire falls the material process. Feeds in again the strip material a step pitch, carries on the next blanking to fall the material process, so moves back and forth carries on. The superposable die is in a press traveling schedule, completes two or the more working procedure ramming molds in the identical location.
Key word Compound mold Falls the material Drills a hole
