Description

Multi-punch die

Technical Field

The utility model discloses be in stamping die technical field, especially relate to a many drift moulds.

background

The cold stamping die is a special tool which applies deformation force to a plate placed in the die at room temperature and obtains product parts with certain shapes, sizes and performances by applying the deformation force on the plate at room temperature and being arranged on a press machine.

The published Chinese utility model patent has the publication number: CN101850385A, patent name: the utility model provides a quick stamping die of drift is buckled in area, application date: 20100415, it discloses a quick stamping die of area drift of buckling, including an last mould and a lower mould, it has the space that is used for the shaping product to reserve between last mould and the lower mould, wherein, go up the mould and mainly overlap in proper order by upper die base, punch holder, upper back board, cope match-plate pattern and form, and wherein, the lower mould is overlapped in proper order by lower bolster, die holder and is put, the punch holder vertical fixation has the half-cut drift, the punch holder vertical fixation has the drift of buckling that is used for bending the product. According to the rapid stamping die with bending impact, when the upper die moves downwards, the bending punch and the half-cutting punch also move downwards along with the upper die, a product is cut by the half-cutting punch, and then the cut product is bent by the bending punch, so that the purpose of one-step forming is achieved, and the working efficiency is improved; and moreover, the spring is additionally arranged between the upper die holder and the template, so that the stamping precision can be obviously improved, and the production cost of an enterprise is reduced.

At present, a product is produced by using one set of mould in more production, and under the condition that the annual output is not large, the mould is in a non-working state when the mould is large, so that the mould cost is saved, the utilization value of the mould is improved, and part of the mould is made into a plurality of products for sharing.

Disclosure of Invention

An object of the utility model is to provide a can realize cold stamping die of punch press of many drifts sharing.

The utility model provides a multi-punch die, which comprises an upper die base 1, a lower die base 2, an upper die frame 6 arranged on the upper die base 1, a lower die frame 7 arranged on the lower die base 2, a punch groove arranged in the upper die frame 6, a punch 3 arranged in the punch groove, and a female die arranged corresponding to the punch 3;

A plurality of punches are arranged in the upper die frame 6, and each punch is internally provided with one punch 3; the plurality of punches are different in size; the punch 3 is detachable.

In this embodiment, the punch 3 is preferably cylindrical.

In the present embodiment, preferably, the plurality of punches 3 are arranged at equal intervals.

In this embodiment, preferably, the plurality of punches 3 have different diameters and respectively correspond to the plurality of punch grooves one by one; the plurality of punches 3 are arranged in order from small to large in diameter.

In the preferred embodiment, among the plurality of punches 3 arranged in the order of the smaller diameter to the larger diameter, the first punch has a diameter of 78mm, and the second punch has a diameter of 141.6 mm.

in the present embodiment, preferably, of the plurality of punches 3 arranged in order from the smaller diameter to the larger diameter, the third punch has a diameter of 176 mm.

In this embodiment, preferably, of the plurality of punches 3 arranged in order from the smaller diameter to the larger diameter, the fourth punch has a diameter of 195 mm.

The beneficial effects of the utility model are that save the mould cost, improve the utilization ratio of mould.

Drawings

FIG. 1 is a schematic structural view of the present invention;
