Description

The new type of continuous mould

Technical field

The utility model relates to a kind of diel, relates in particular to a kind of new type of continuous mould.

Background technology

Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc. have direct relation with mould design and manufacturing.Usually need punching on the workpiece of blanking in punch process, use existing mould to need earlier in blanking die the workpiece blanking is put into the perforating die punching then, operation is many like this, production efficiency is low, and workpiece needs resetting, has influenced precision and the quality of product.Generally be the less aperture in aperture in the hole of blank upper punch in addition; when carrying out the aperture moulding; its corresponding punch is elongate rod; strength and stiffness are poor, and punch is easy to produce flexural deformation and fractures when stamping-out, when when thicker towards material; the easier fracture of punch; to often shut down the replacing punch, reduce operating efficiency, increase die cost.

Summary of the invention

At the problem that above-mentioned prior art exists, the utility model provides a kind of new type of continuous mould, can successively finish punching and the blanking of workpiece in a mold, has improved production efficiency, has avoided the workpiece resetting, has improved the product precision.And piercing punch of the present utility model is frangibility not, long service life, and mold production process is simple, has reduced die cost, and is very practical.

The technical solution of the utility model is: a kind of new type of continuous mould, 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 die, the upper bolster lower surface is provided with blanking punch, the position corresponding with blanking punch has blanking type hole on the die, slip cap is connected to and suppresses stripper on the blanking punch, suppressing stripper flexibly connects by discharging screw and upper bolster, be socketed with rubber blanket on the discharging screw, the upper bolster lower surface is provided with lower bolster near the position of blanking punch, and the lower bolster lower surface is provided with piercing punch, and the position corresponding with piercing punch has the punching hole type hole on the die, piercing punch is socketed on and suppresses in the stripper, and can suppress relatively on the stripper, following mobile.

As preferably, be provided with upper padding plate between blanking punch and the upper bolster, blanking punch is fixedly connected on the upper padding plate lower surface by upper mounted plate, and lower bolster is fixedly connected on the upper mounted plate lower surface, and piercing punch is fixedlyed connected with lower bolster by bottom plate.

As preferably, suppress the stripper upper surface and have the groove that cooperates with bottom plate, described piercing punch is two, and parallel interval is arranged at the lower bolster lower surface, and the aperture in blanking type hole increases from top to bottom gradually, and the punching hole type hole is up-small and down-big shoulder hole.

The beneficial effects of the utility model are: be respectively arranged with blanking punch and piercing punch on the utility model upper bolster, be respectively arranged with blanking type hole and punching hole type hole on the die, during punching production, billot is finished punching earlier under the effect in piercing punch and punching hole type hole, then billot is moved to the position of blanking punch, blanking punch and blanking type hole cooperate finishes blanking, movement along with billot, the billot of back can be finished punching and blanking processing continuously, easy to process, the production efficiency height need not take out workpiece between blanking and the punching two procedures, avoid the workpiece resetting, improved precision and the quality of workpiece.Piercing punch of the present utility model is arranged on the lower bolster, and fix by bottom plate, such structure has shortened the length of piercing punch greatly, avoided piercing punch in the stamping-out process, to produce flexural deformation and fractureed, the strength and stiffness of piercing punch have been improved greatly, prolong the service life of piercing punch, need not often change piercing punch, improved operating efficiency.And mold production process is simple, and die cost is low, and is very practical.
