Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of punch-die at upper composite die.
Background technology
Pull and stretch is a kind of common mechanical processing technique, is the process for stamping and forming of making cup shell of the plane slab, claims again to draw.Can make the hollow object of cylindrical shape, sphere, taper, box-like, stairstepping, flanged and other complicated shapes by pull and stretch.Its shaping generally is to finish by Drawing Die, before using Drawing Die processing, need to carry out blanking processing to the band material, if the employing single die separates blanking and drawing sequence, then between the mould of each operation, want resetting, because the position error of each operation is larger, the percent defective of part is higher during production, and productivity ratio is very low, causes production cost to increase; If adopt progressive die production, owing to reasons such as the skill otch that goes into operation, stock utilization can reduce again makes production cost increase equally.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of punch-die at upper composite die, can in a mold, finish blanking and the pull and stretch processing of workpiece, avoided resetting between two-step, reduce position error, reduced percent defective, can finish simultaneously two operations, improve production efficiency, reduced production cost.
The technical solution of the utility model is: a kind of punch-die is at upper composite die, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with guide pin bushing, the die shoe upper surface is provided with the guide pillar that cooperates with guide pin bushing, the upper bolster lower surface is provided with punch-die, the position that the die shoe upper surface is corresponding is provided with blanking die, be provided with the pull and stretch punch in the blanking die, the pull and stretch punch is corresponding with the die hole position of punch-die, punch-die is socketed with stripper outward, be provided with the head part device in the die hole of punch-die, the pull and stretch punch is socketed with blank holder outward, and the blank holder lower end is connected with the bullet apical organ, and described bullet apical organ comprises push rod, the push rod upper end is connected with blank holder, and the lower end is connected in the die shoe by the flanging spring.
As preferably, described head part device comprises makes bar, stretches out the die shank upper surface on making bar, the lower end is connected with pressing plate, and pressing plate relatively die hole slides, and blanking die inwall upper end is the conical surface, the blanking die upper surface is provided with dog screw, and the stripper lower surface has the groove that cooperates with dog screw.
As preferably, punch-die is connected in the upper bolster lower surface by upper mounted plate, is provided with upper padding plate between punch-die and the upper bolster; Blanking die and pull and stretch punch are connected in the die shoe upper surface by bottom plate, are provided with lower bolster between pull and stretch punch and the die shoe.
The beneficial effects of the utility model are: use the utility model, can in a mold, carry out the operation of blanking and pull and stretch, avoided resetting between two-step, reduce position error, reduced percent defective, can finish simultaneously two operations, improved production efficiency, reduced production cost, the dog screw on the blanking die can help location, the positioning accuracy when having guaranteed punching press.Head part device and blank holder can provide enough pressure when pull and stretch, avoid workpiece wrinkling, have guaranteed the surface quality of product, and be very convenient and practical.
