Abstract
The utility model discloses a compound die with a shaping and trimming concave die positioned above, and relates to a stamping die which comprises an upper die seat, a lower die seat and a die shank. A guide sleeve is arranged on a lower surface of the upper die seat, a guide column matched with the guide sleeve is arranged on an upper surface of the lower die seat, the upper die seat is provided with a shaping and trimming convex die which is provided with a trimming cutting edge, the lower surface of the upper die seat is provided with the shaping and trimming concave die, a lower end of a material beating rod is connected with a material pressing plate which can slide relative to a concave die hole, an upper end of the material beating rod is extended out of an upper surface of the die shank to be connected with a material pressing spring, the upper surface of the lower die seat closely clings to the shaping and trimming convex die and is provided with two waste material cutters, and the cutting edge peaks of the waste material cutters are lower than a trimming cutting edge surface of the shaping and trimming convex die. The compound die with the shaping and trimming concave die positioned above can complete shaping and trimming after drawing processing of workpieces simultaneously, repeated positioning between two processes is avoided, positioning errors are reduced, rejection rate is lowered, production efficiency is improved, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of shaping trim die at upper compound 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, usually need surface of the work is carried out Shape correction after using the Drawing Die pull and stretch to finish, guarantee size, form accuracy and the surface quality of workpiece, its oral area generally all not concordant flange can occur after drawing part is shaped in addition, the processing of need to cutting edge, if the single die tool is adopted in shaping and side cut, 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, and is very uneconomical.Cut flanged ring is enclosed within on the side cut punch after using in addition existing edger side cut to finish, and is not easy to take out, and causes often shutting down cleaning, has reduced operating efficiency.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of shaping trim die at upper compound die, can finish simultaneously shaping and side cut after the workpiece pull and stretch is processed, avoided resetting between two-step, reduced position error, reduce percent defective, and improved production efficiency, reduced production cost.
The technical solution of the utility model is: a kind of shaping trim die is at upper compound 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 die shoe upper surface is provided with shaping side cut punch, be provided with the side cut cutting edge on the described shaping side cut punch, the position that the upper bolster lower surface is corresponding with shaping side cut punch is provided with the shaping trim die, be provided with knockout rod in the die hole of shaping trim die, the knockout rod lower end is connected with holding pad, holding pad relatively die hole slides, and the knockout rod upper end is stretched out the die shank upper surface and is connected with the binder spring; The die shoe upper surface is close to shaping side cut punch and is symmetrically arranged with two scrap cutters, and the cutting edge peak of scrap cutter is lower than the side cut edge surface of shaping side cut punch.
As preferably, the lower end lateral wall of described shaping trim die is the conical surface, and upper bolster and die shoe adopt the Q235 steel plate to make, and the shaping trim die adopts carbide alloy to make.
As preferably, be provided with upper padding plate between shaping trim die and the upper bolster, the shaping trim die is connected in the upper padding plate lower surface by upper mounted plate; Be provided with lower bolster between shaping side cut punch and the die shoe, shaping side cut punch is connected in the lower bolster upper surface by bottom plate.
The beneficial effects of the utility model are: use the utility model that the flange drawing part is added man-hour, the operation that shaping and flange are cut edge behind the finishing drawing simultaneously, avoided resetting between two-step, reduced position error, reduced percent defective, can finish simultaneously two operations, improved production efficiency, reduced production cost, holding pad adds in shaping can apply enough pressure to workpiece man-hour, prevent that workpiece is wrinkling, after side cut is finished, workpiece can be released from the die hole of shaping trim die, avoid workpiece to be stuck in the die hole.After side cut was finished, upper bolster continued to move down, and the lower surface of shaping trim die and scrap cutter bump cut off the flange that is enclosed within on the shaping side cut punch, make things convenient for the taking-up of flange, have improved operating efficiency, and be very convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of shaping trim die is at upper compound die, comprise upper bolster 5, die shoe 1 and die shank 7, in the present embodiment, as preferably, upper bolster 5 and die shoe 1 adopt the Q235 steel plate to make good combination property, long service life.Die shank 7 adopts 45 steel to make.Upper bolster 5 lower surfaces are provided with guide pin bushing, and die shoe 1 upper surface is provided with the guide pillar that cooperates with guide pin bushing.Die shoe 1 upper surface is provided with shaping side cut punch 3, be provided with the side cut cutting edge on the described shaping side cut punch 3, upper bolster 5 lower surfaces and shaping side cut punch 3 corresponding positions are provided with shaping trim die 9, and as preferably, shaping trim die 9 adopts carbide alloy to make.Be provided with knockout rod 8 in the die hole of shaping trim die 9, knockout rod 8 lower ends are connected with holding pad, and holding pad relatively die hole slides, and knockout rod 8 upper ends are stretched out die shank 7 and are connected with the binder spring.Die shoe 1 upper surface is close to shaping side cut punch 3 and is symmetrically arranged with two scrap cutters 10, and the cutting edge peak of scrap cutter 10 is lower than the side cut edge surface of shaping side cut punch 3.
In the present embodiment, as preferably, the lower end lateral wall of described shaping trim die 9 is the conical surface, can effectively reduce the impact of shaping trim die 9 and scrap cutter 10 collisions.
In the present embodiment, as preferably, be provided with upper padding plate 6 between shaping trim die 9 and the upper bolster 5, shaping trim die 9 is connected in upper padding plate 6 lower surfaces by upper mounted plate 4; Be provided with lower bolster 11 between shaping side cut punch 3 and the die shoe 1, shaping side cut punch 3 is connected in lower bolster 11 upper surfaces by bottom plate 2.As preferably, scrap cutter 10 press-fits on bottom plate 2.
