Abstract
The utility model discloses a top-discharging blanking die and relates to a stamping die. The top-discharging blanking die comprises an upper die holder, a lower die holder, a die handle, a guide sleeve and a guide column. A male die is disposed on the upper surface of the lower die holder, and a female die is disposed on the lower surface of the upper die holder. An ejector device is arranged in a female die hole and fixedly connected with the lower surface of the upper die holder through a disc-shaped ejector spring. A discharge plate is arranged on the male die and connected on the outer surface of the male die in a sleeved mode. A discharge bolt is arranged on the discharge plate, a discharge rubber pad is sleeved outside the discharge bolt, and the discharge plate is made of 45 steel. The top-discharging blanking die is simple in structure, and is capable of enabling work pieces to always keep flat during a stamping process, reducing burrs, avoiding edge curling, improving accuracy and surface quality of products, and lowering rejection rate.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of top discharge blanking die.
Background technology
Stamping die is a kind of commercial production common equipment, and it can carry out processing and forming such as punching and blanking, and existing stamping die is when the thin material of punching press; Strip is in free state, and when punching or blanking, strip is easy to wrinkling; Influence the precision of product, increased percent defective, even adopt stripper to suppress discharging; Also, make the flatness of product surface poor, influence surface quality of products because can not prevent inadequately that to the pressure of strip the stopping materials strip vault is curved.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of top discharge blanking die, and is simple in structure; Make workpiece in punching course, be in formation state all the time, reduce burr, avoid edge-curl phenomenon; Improve the precision and the surface quality of product, reduced percent defective.
The technical scheme of the utility model is: a kind of top discharge blanking die; Comprise upper bolster, die shoe, die shank, guide pin bushing and guide pillar; The die shoe upper surface is provided with punch, and the upper bolster lower surface is provided with die, and die is provided with ejector in the hole; Ejector is fixedly connected with the upper bolster lower surface through the head part spring, and said head part spring is a disc spring; Punch is provided with stripper, and stripper is socketed on the punch outer surface, and stripper is provided with the discharging screw, and the discharging screw is socketed with the discharging rubber blanket outward, and said stripper adopts 45 steel to process.
As preferably, punch is fixedly connected on the die shoe through punch retainer, is provided with convex mould pad between punch and the die shoe, and convex mould pad adopts 45 steel to process.
As preferably, be provided with the die backing plate between said die and the upper bolster, the die backing plate adopts 45 steel to process, and the position that the die backing plate is corresponding with the die hole has the through hole that can hold the head part spring.
As preferably, said discharging rubber blanket adopts polyurethane rubber to process.
The beneficial effect of the utility model is: when using the utility model punching press, and the stripper acting in conjunction of the ejector of top and below, the head part spring adopts disc spring; Enough elastic force can be provided, tightly push down strip, the elasticity vault that suppresses strip is curved; Make strip in punching course, be in formation state all the time, reduce burr, avoid edge-curl phenomenon; The precision and the surface quality of product have been improved; Reduce percent defective, to the damage of upper bolster and die shoe, prolonged the service life of the utility model when die backing plate and convex mould pad can reduce punching press.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of top discharge blanking die; Comprise upper bolster 7, die shoe 1, die shank 6, guide pin bushing and guide pillar (guide pin bushing and guide pillar do not draw); In the present embodiment, as preferably, said upper bolster 7, die shoe 1 and die shank 6 adopt the Q235 steel plates to process; Good combination property, long service life.
Die shoe 1 upper surface is provided with punch 2, and in the present embodiment, as preferably, punch 2 is fixedly connected on the die shoe 1 through punch retainer 12, is provided with convex mould pad 13 between punch 2 and the die shoe 1, and convex mould pad 13 adopts 45 steel to process.The impact of 2 pairs of die shoes 1 of punch when convex mould pad 13 can reduce punching press, the service life of prolongation die shoe 1.Upper bolster 7 lower surfaces are provided with die 9, are provided with ejector 4 in the die hole, and ejector 4 is fixedly connected with upper bolster 7 lower surfaces through head part spring 5, and said head part spring 5 is a disc spring, and enough pressure-plate-forces can be provided.Punch 2 is provided with stripper 3, and stripper 3 is socketed on punch 2 outer surfaces, and stripper 3 is provided with discharging screw 11; Discharging screw 11 is outer to be socketed with discharging rubber blanket 10, in the present embodiment, and as preferably; Said discharging rubber blanket 10 adopts polyurethane rubber to process; Its wearability and oil resistivity are good, long service life, and bumper and absorbing shock property is good.Said stripper 3 adopts 45 steel to process.When discharging rubber blanket 10 does not compress, the flush of the upper surface of stripper 3 and punch 2 or exceed punch 2 upper surface 2-3mm.When punch forming, stripper 3 can workpiece pressing, guarantees the positioning accuracy of workpiece, avoids workpiece wrinkling, and after punching press was accomplished, stripper 3 is 2 dischargings of help punch under the effect of discharging rubber blanket 10.When moving on the upper bolster 7, ejector 4 resets, and workpiece is released the die hole.
In the present embodiment, as preferably, be provided with die backing plate 8 between said die 9 and the upper bolster 7, die backing plate 8 adopts 45 steel to process, and the position that die backing plate 8 is corresponding with the die hole has the through hole that can hold head part spring 5.The impact of 9 pairs of upper bolsters 7 of die when die backing plate 8 can reduce punching press, the service life of prolongation upper bolster 7.
