Abstract
The utility model relates to the technical field of precision punching dies for automobiles, in particular to an improved precision punching die for high strength heavy plates. The precision punching die comprises an upper die, a lower die, a male die and a female die and is characterized in that the male die is mounted at the lower part of the upper die; and the female die is mounted at the upper part of the lower die. Compared with the prior art, the utility model is changed slightly on the basis of an original precision punching die, so that the euphotic zone on the edge of a sheared product is up to over 85 percent and close to 90 percent, thereby ensuring the quality of precision punching, improving production efficiency and saving the production and processing cost.
Description
[technical field]
The utility model relates to automobile fine blanking die technical field, specifically a kind of improved high-strength plank fine blanking die.
[background technology]
Existing fine blanking die die is installed in the patrix lower surface, punch is installed in the counterdie upper surface, be to be that the benchmark maintenance is motionless with the punch like this, driving die by stamping machine with pressing plate compacting patrix moves downward, thereby shear out the required moulding of slab that automobile is used, and the size of the contact-making surface of die compacting usefulness is greater than the contact-making surface of punch compacting usefulness, and the edge euphotic belt of shearing the slab that comes out like this only reaches 40%-50%, and the burr part that relative needs are handled is just many.
[summary of the invention]
The purpose of this utility model is to overcome the prior art deficiency, and the position of concave, convex mould is changed, and is as the criterion with die, and the punch size is taked the mode bigger than die, is commonly called as the negative clearance punching press and reaches the purpose that essence is dashed.
For achieving the above object, a kind of improved high-strength plank fine blanking die of design comprises upper die and lower die, punch, die, and it is characterized in that: described punch is installed in the patrix bottom, and described die is installed in counterdie top.
Described punch basal surface size is greater than die upper surface size.
The utility model is compared with prior art, on the basis of original fine blanking die, changes slightly, the euphotic belt of shearing the product edge of coming out is reached more than 85%,, guaranteed smart quality of dashing near 90%, improve production efficiency, saved the cost of production and processing.
[description of drawings]
Fig. 1 is the structural representation among the utility model embodiment.
Referring to Fig. 1,1 is patrix, and 2 is counterdie, and 3 is punch, and 4 is die, and 5 is processed product.
[specific embodiment]
Engaging accompanying drawing below is further described the utility model.
Punch 3 is installed in patrix 1 bottom, die 4 is installed in counterdie 2 tops, and punch 3 basal surfaces are dimensioned to upper surface size greater than die 4, when punching press, processed product 5 is placed between the concave, convex mould, utilize stamping machine with the pressing plate on patrix 1 top to pressing down, drives punch 3 and move downward, and the die 4 on the counterdie 2 keeps motionless, be benchmark like this with the die, and take the punch size mode bigger than die, and be commonly called as the negative clearance punching press, realize the purpose that essence is dashed.
