Abstract
The utility model relates to the technical field of punching, in particular to a punch press die used for machining a sheet stamping part semi-fine-blanking product by means of an ordinary punch press. The punch press die comprises an upper die and a lower die, wherein a plunger chip and an unloader are arranged on the upper die, an R corner is arranged on a cutting edge of the upper die, a gap is reserved between the upper die and the lower die after the upper die and the lower die are pressed together, and the R corner ranges from R0.2 to R0.5. According to the punch press die used for machining the sheet stamping part semi-fine-blanking product, the semi-fine-blanking product can be machined by means of the ordinary punch press through the improvement of an ordinary punch press die, and then product quality and production efficiency are greatly improved.
Description
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of common punch press that utilizes and produces the punching machine mold that sheet stamping member half essence is rushed product.
Background technology
for dimensional accuracy and the higher sheet stamping member of appearance requirement, for guaranteeing its quality, in production, often adopt essence punching or half fine blanking technology means, need to be upper could the realization of smart impact machine (accurate hydraulic press), this kind of equipment is compared with ordinary press and is had high, the inefficient shortcoming of cost, is unfavorable for the reduction of product cost and the raising of production efficiency.
Summary of the invention
For the problems referred to above, the utility model provides a kind of punching machine mold that rushes product for processing sheet stamping parts half essence.
The punching machine mold that the utility model provides, comprises upper die and lower die, and patrix is provided with drift and discharger, and patrix cutting edge is provided with R angle, gapped between the two after upper die and lower die press together.The scope at described R angle is R0.2-R0.5.Between upper die and lower die, interstice coverage is 0.05-0.08mm.The utility model improves the mould of common punch press, repairs the R angle of suitable size on patrix cutting edge, reduces the impulsive force that while falling to rushing, mould bears, and extends its service life, and can improve stamping-out surface roughness, improves surface quality.Meanwhile, the ，Shi Gai gap, gap dwindling between common punch press upper die and lower die is slightly larger than traditional fine blanking die, can when guaranteeing product size precision, reduce impulsive force.
The utility model, by common punch press mould is improved, utilizes common punch press just can process half essence and rushes product, and product quality and production efficiency are greatly improved.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional schematic;
Fig. 2 is the partial enlarged drawing of Fig. 1;
In figure, 1, drift, 2, discharger, 3, patrix, 4, counterdie, 5, R angle.
The specific embodiment
A kind of punching machine mold that rushes product for processing sheet stamping parts half essence, as shown in Figure 1, 2, comprise patrix 3 and counterdie 4, in the middle of patrix 3, be provided with drift 1, between drift 1 and patrix 3, be provided with discharger 2, below patrix and discharger, drift and discharger contact position, on cutting edge, be provided with R angle 5, R angular region is R0.2-R0.5.Gapped between the two after patrix 3 and counterdie 4 press together, interstice coverage is 0.05-0.08mm.
