THE BENGDING DIE DESIGN
This mold design topic for the bending die, falls the material, the punch holes superposable die, this components need three working procedures to complete. Has manifested the complex components design request, the content and the direction. Has certain design significance, through further strengthened the elementary knowledge to this components mold design which the designer ramming mold designs, for designed more complex flushes the die to complete the upholstery and to absorb a deeper this experience.
This design utilization ramming mold design and the manufacture craft elementary knowledge, has first analyzed the end cover components contour, the size, the precision request, has carried on the craft analysis, considered this components are the circular components, is high to the proper alignment request, therefore uses the superposable die craft plan. Then the basis components external dimensions computation semifinished materials overall size, a design row of specimen map and the computation material use factor and the center of pressure last count is present at work makes the partial sizes, the mold overall size, the overall size including the work spare part structural design, the dumping device design as well as the fixed components design and the utilization.
This mold characteristic is the small end cover drawing, falls the material, the punch holes superposable die.
The formed push pedal goes against in the ball, under the roof bar function, is in on most the position, the nursery lives the semifinished materials, the top die part drops, the use convex-concave mold and the formed push pedal carry on the drawing and press the shape, the top die continue to drop, impel the formed push pedal to drop, this time by falls the material concave mold, the convex-concave mold carries on falls the material, then flushes the bottom hole. When formed push pedal and dead plate contact, then carries on the reshaping. Is loaded with 6 roof bars in the formed push pedal, operates when the mold may cause the work piece to lift, is advantageous for takes.
Key words: The bending die Superposable die
