Abstract

The utility model discloses a right-handed compound die, and relates to a stamping die. The compound die comprises an upper die holder, a lower die holder and a die handle, wherein a guide sleeve is arranged on the lower surface of the upper die holder; a guide pin matched with the guide sleeve is arranged on the lower die holder; a convex-concave die is arranged on the lower surface of the upper die holder; a blanking female die is arranged on the upper surface of the lower die holder; a deep drawing male die is arranged in the blanking lower die, and corresponds to a lower die hole of the convex-concave die in position; a discharging plate is sleeved outside the convex-concave die; an ejecting piece device is arranged in the lower die hole of the convex-concave die; an edge pressing ring is sleeved outside the deep drawing male die; an elastic ejector is arranged at the lower end of the edge pressing ring; the elastic ejector comprises an ejecting rod; and the upper end of the ejecting rod is connected to the edge pressing ring, and the lower end is connected to the lower die holder through a rubber pad. The right-handed compound die can realize blanking and deep drawing processing of a workpiece in a set of die, can avoid repeated positioning of the two processes to reduce positioning error and scrap rate, can complete two processes simultaneously, improves production efficiency, reduces manufacturing cost, and is very practical.

Description

The formal dress composite die
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of formal dress composite die.
Background technology
Pull and stretch is a kind of common mechanical processing technique, is to make the process for stamping and forming of cup shell of the plane slab, claims again to draw.Can make the hollow object of cylindrical shape, spherical, taper, box-like, stairstepping, flanged and other complicated shapes by pull and stretch.Its shaping is generally to complete 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, want resetting between the mould of each operation, because the position error of each operation is larger, during production, the percent defective of part is higher, and productivity ratio is very low, causes production cost to increase; If adopt progressive die production, due 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 formal dress composite die, can complete blanking and the pull and stretch processing of workpiece in a mold, avoid resetting between two-step, reduced position error, reduced percent defective, can complete simultaneously two operations, improve production efficiency, reduced production cost, very practical.
the technical solution of the utility model is: a kind of formal dress 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 coordinates 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 blanking die, the die hole position of pull and stretch punch and punch-die is corresponding, 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, the blank holder lower end is connected with the bullet apical organ, described bullet apical organ comprises push rod, the push rod upper end is connected with blank holder, the lower end is connected in die shoe by rubber blanket.
As preferably, described head part device comprises makes bar, beats the bar upper end and stretches out the die shank upper surface, the lower end is connected with pressing plate, and pressing plate die hole relatively 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 coordinates 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 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 die shoe.
The beneficial effects of the utility model are: use the utility model, can carry out the operation of blanking and pull and stretch in a mold, avoided resetting between two-step, reduce position error, reduced percent defective, can complete simultaneously two operations, improved production efficiency, reduced production cost, the dog screw on 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 practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
