Abstract

The utility model relates to a forming stamping die structure for processing PC materials into mesh materials, in particular to a stamping die structure of PC plates. The stamping die structure sequentially comprises an upper die base, a punch insert, a punch retainer, a stripper plate, a concave die, a concave die base plate and a lower die base, as well as punching pins fixed at the middle of the punch insert. The stamping die structure is characterized in that a blanking hole is arranged in the middle of the concave die and takes the shape of a horn which is narrow at the upper part and wide at the lower part; for the blanking hole, the front round hole is 6mm Phi, the rear hole is 12mm Phi, the plate thickness is 20 Phi, and the 12 Phi surface is milled with the depth of 18mm; and the punching pins are designed in step shape and arranged in the punch insert in array. By the pressure expansion processing of the horn blanking hole on the concave die plate, the stamping die causes blanking to be convenient and quick and ensures a product is stamped as a neat mesh product without burrs, crush and the like.

Description

PC plate stamping mode structure

Technical field:

The utility model relates to a kind of machinery processing apparatus, especially relates to a kind of blanking controllable orientation, guarantee product strike out netted, product surface is smooth, the PC plate stamping mode structure that do not have burr, weighs wounded.

Background technology:

In the existing technical field that manufactures a product, the application of diel more and more widely, it is constituted by the punch-die that cooperates up and down usually, each punch-die all has a specific die holder, is provided with the template of specific moulding in the periphery of die holder.Usually, pressing according to the punching press raw material, material-dropping hole in the design die, but can there be the cutting edge part in die surface, during blanking, need extruding energetically just can make moulding material break away from mould, these material-dropping holes are usually in punching course, because the blanking extruding can produce wearing and tearing, collapse phenomenons such as scarce, and make the product that obtains imperfect, burr are arranged, weigh wounded, be out of shape, mechanical trauma such as bending.

Summary of the invention:

Technical problem to be solved in the utility model provide a kind of make blanking easily, to guarantee that product strikes out web-shaped product smooth, the PC plate stamping mode structure that do not have burr, weighs wounded.

The technical scheme in the invention for solving the technical problem is: a kind of PC plate stamping mode structure, comprise upper bolster, punch insert, punch retainer, stripper plate, die, die backing plate, die shoe successively, and the pin that dashes that is fixed on the punch insert centre, it is characterized in that: the centre at described die offers material-dropping hole, described material-dropping hole presents up-narrow and down-wide horn-like, material-dropping hole front circular hole ￠ 6mm, reverse side ￠ 12mm, thickness of slab is 20mm, from the degree of depth of the dark 18mm of ￠ 12 facing cuts.

In order to reduce in the punching press punch insert to the extruding force of material in the die, the punching press ￠ 6mm that portals, spacing is the netted sheet material of 9mm, describedly becomes stepped towards pin, the afterbody of broad is embedded in the punch insert, and becomes array-like to arrange.

After adopting said structure, its advantage is: upper bolster utilizes it that train wheel bridge and upper padding plate are fixed together, and transmits pressure, stepped under the guiding of pin, punch-die can well be cooperated, punch retainer prevents punching pin afterbody crush injury die holder, increases mold height, unloads material by stripper plate behind the binder, in punching course, reduce extruding force by the horn-like material-dropping hole in the die, make blanking easily, to guarantee that product strikes out web-shaped product smooth, do not have burr, weigh wounded etc.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the simple diagram of the utility model in concrete operations;

Fig. 2 is a die vertical view in the utility model;

Fig. 3 is the enlarged diagram of single material-dropping hole in the utility model;

Fig. 4 is towards the front view of pin in the utility model.

Among the figure: 1, two 6, the die backing plate 7 of upper bolster 2, punch insert 3, punch retainer 4, stripper plate 5, die 5-1, material-dropping hole 5-2, screw hole 5-3 pin-and-hole 5-4, guide pin bushing, die shoe 8, towards pin

The specific embodiment:

Fig. 1, a kind of PC plate stamping mode structure shown in Figure 2, comprise upper bolster 1, punch insert 2, punch retainer 3, stripper plate 4, die 5, die backing plate 6, die shoe 7 successively, and be fixed on and dash pin 8 in the middle of the punch insert 2, it is characterized in that: offer material-dropping hole 5-1 in the centre of described die 5, described material-dropping hole presents up-narrow and down-wide horn-like, effect is the reduction extruding force, guarantees that blanking is complete, avoids mechanical wear.

Single material-dropping hole 5-1 shown in Figure 3, material-dropping hole 5-1 face circular hole ￠ 6mm, reverse side ￠ 12mm, thickness of slab are 20mm, from the degree of depth of the dark 18mm of ￠ 12 facing cuts, blanking has the upper surface hole extruding to enter the downside macropore, guarantees that blanking is easy, can not produce burr.

Shown in Figure 4 towards pin 8, become stepped, the afterbody of broad is embedded in the punch insert 2, and becomes array-like to arrange, and it is netted making presswork, and stair-stepping design has guaranteed the flatness of presswork.

Utilization drives the motion of punch-die towards pin 8, offer the two 5-4 of guide pin bushing at 5 four jiaos of places of described die, offer two row screw hole 5-2 and pin-and-hole 5-3 on the described die 5 respectively, the position of fixed punch belling die, upper bolster 1 utilizes it that train wheel bridge and punch insert fixed head 3 are fixed together, and transmission pressure, under the guiding of pin 8, punch-die can well be cooperated, punch insert 2 fixed heads prevent punching pin afterbody crush injury die holder, increase mold height, unload material by stripper plate 4 behind the binder, in punching course, reduce extruding force by the horn-like material-dropping hole 5-1 in the die 5, make blanking easy, arrange towards pin 8 array-like in punch insert 2, guarantee that product strikes out web-shaped product, product surface is smooth, does not have burr, weigh wounded etc.
