Description

Soft thin material diel

Technical field

The utility model relates to a kind of diel, especially a kind of soft thin material diel.

Background technology

At present, while using the soft thin material product of mould structure stamping-out, owing to adopting clearance blanking, product section is that tear fracture produces, and product stamping-out section is not good like this, easily produces burr.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of when soft thin material product stamping-out the section burr of product have and well improve effect, can reduce the soft thin material diel that repairs a die number of times and enhance productivity.

The technical scheme providing according to the utility model, described soft thin material diel, comprise upper bolster and die shoe, lower surface at upper bolster is fixed with upper padding plate, on upper padding plate, be fixed with drift, lower surface at upper padding plate is fixed with train wheel bridge, below train wheel bridge, be provided with baffle plate, at the lower surface of baffle plate, be fixed with de-plate, described drift is through baffle plate and upper de-plate, on train wheel bridge, be slidably fitted with contour cover, the height of contour cover is greater than the thickness of train wheel bridge, the lower surface of contour cover and the upper surface of baffle plate offset, baffle plate with on be fixed with construction bolt on de-plate, washer rack on construction bolt is located on the upper surface of contour cover, upper surface at die shoe is fixed with lower bolster, at the upper surface of lower bolster, is fixed with lower bolster, at the upper surface of lower bolster, is provided with the edge of a knife, and the bottom size of drift is greater than the size of the edge of a knife, and the bottom size of drift and the size of the edge of a knife are matched in clearance.

Also be provided with spring, the upper end of spring and the lower surface of upper bolster offset, and the bottom of spring and the upper surface of baffle plate offset.

On upper padding plate, be fixed with guide pillar, on baffle plate, offer the baffle plate pilot hole coordinating with guide pillar, on upper de-plate, offer the upper de-plate pilot hole coordinating with guide pillar, on die shoe, offer the die shoe pilot hole coordinating with guide pillar.

The utility model is when soft thin material product stamping-out, and the section burr of product have the good effect of improving, thereby meets the quality requirement of product, and the utility model has reduced the number of times that repairs a die, and has improved production efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.

This soft thin material diel, comprise upper bolster 1 and die shoe 12, lower surface at upper bolster 1 is fixed with upper padding plate 4, on upper padding plate 4, be fixed with drift 3, lower surface at upper padding plate 4 is fixed with train wheel bridge 5, below train wheel bridge 5, be provided with baffle plate 7, at the lower surface of baffle plate 7, be fixed with de-plate 8, described drift 3 is through baffle plate 7 and upper de-plate 8, on train wheel bridge 5, be slidably fitted with contour cover 13, the height of contour cover 13 is greater than the thickness of train wheel bridge 5, the upper surface of the lower surface of contour cover 13 and baffle plate 7 offsets, baffle plate 7 with on be fixed with construction bolt on de-plate 8, washer rack on construction bolt is located on the upper surface of contour cover 13, upper surface at die shoe 12 is fixed with lower bolster 11, upper surface at lower bolster 11 is fixed with lower bolster 10, upper surface at lower bolster 10 is provided with the edge of a knife 14, and the bottom size of drift 3 is slightly larger than the size of the edge of a knife 14, and the bottom size of drift 3 and the size of the edge of a knife 14 are matched in clearance.

Also be provided with spring 2, the lower surface of the upper end of spring 2 and upper bolster 1 offsets, and the upper surface of the bottom of spring 2 and baffle plate 7 offsets.

On upper padding plate 4, be fixed with guide pillar 6, on baffle plate 7, offer the baffle plate pilot hole coordinating with guide pillar 6, on upper de-plate 8, offer the upper de-plate pilot hole coordinating with guide pillar 6, on die shoe 12, offer the die shoe pilot hole coordinating with guide pillar 6.

The material hardness of described drift 3 is greater than the material hardness of lower bolster 10.

In the utility model, drift 3 adopts negative clearance to coordinate with the edge of a knife 14 sizes of lower bolster 10, and drift 3 adopts hard material, and lower bolster 10 adopts soft material, like this when product stamping-out, product 9 is clamp-oned the edge of a knife 14 of lower bolster 10 by force, can guarantee the cross section quality of product 9 like this, make the section of product 9 bright and clean without burr, through producing for a long time, if find, the edge of a knife 14 wearing clearances of lower bolster 10 become large, affect product quality, the edge of a knife 14 around can be beaten, make the edge of a knife 14 gaps reach perfect condition, thereby continue to produce.

Drift 3 be negative clearance stamping-out with the edge of a knife 14 of lower bolster 10, and soft thin material product size is followed drift, and to be that material is stressed squeeze off the generation of flowing to product section, therefore section situation is better.
