Abstract

The utility model relates to a punching mould which is composed of an upper mould (1), a lower mould (2), a punching needle (3) and a desquamating frame (4). The punch needle is arranged on the upper mould, and the desquamating frame is fixed on the back wall of the lower mould. The upper end of the desquamating frame is bent, and is horizontally extended between the upper mould and the lower mould. A positioning sheet (5) is also arranged between the back wall of the lower mould and the desquamating frame, and the lower end of the desquamating frame is contacted with a spring (6). The inserting depth of the opening profile is controlled through a positioning sheet, and thus the opening position and two selections. The utility model has reasonable design, and convenient use. The not only the work efficiency is raised, but also the material is saved. One mould has two double functions. The utility model is particularly suitable for the working production.

Description

Punching die set

The utility model relates to a kind of machinery processing apparatus, particularly a kind of diel.

At first, the method for metal door and window banding section bar two ends perforate is a hand drill, and its shortcoming is low, the easy deviation of efficient, is unfavorable for large-scale processing, production.The someone utilized mould punching press perforate afterwards, but Mould design can only be opened a kind of hole by a kind of mould, and promptly the distance of hole and section bar end can not be selected.And in fact, the distance of metal door and window banding section bar two ends and respective aperture is different often, and normally an end height, an end are low, and the two differs 2 millimeters.Like this, to above-mentioned section bar perforate, just must use two molds with existing mold.

The purpose of this utility model is to provide a kind of degree of accuracy height, can adapt to the diel of large-scale processing production and energy one mould dual-purpose (the perforate distance has two kinds of selections).

The purpose of this utility model reaches like this: diel is by patrix (1), counterdie (2), form towards pin (3) and furfur frame (4), be installed on patrix towards pin, the furfur frame is fixed in the counterdie rear wall, its upper end is crooked, level stretches between the upper and lower mould, spacer (5) also is housed between counterdie rear wall and the furfur frame, and its lower end contacts with spring (6).

Fig. 1 is vertical section figure of the present utility model.

Fig. 2 is sagittal section figure of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.

Be fixed in patrix (1) towards pin (3), move up and down with patrix.Furfur frame (4) is fixed in counterdie (2), and its upper end is crooked, and level stretches between the upper and lower mould, and when upwards mentioning when finishing towards the pin punching press, the furfur frame can tighten processed section bar, and it is unlikely with carrying on pin, plays demoulding effect.For reaching the purpose of " mould is dual-purpose ", can be on plug-in mounting between counterdie rear wall and the furfur frame spacer (5), spring (6) is equipped with in the spacer below, spacer is because the elastic reaction of spring is in the position that is higher than counterdie blade face at ordinary times, the shape for the treatment of perforate inserts counterdie, the end of section bar can not be touched with the furfur bridge joint of counterdie back by stopping of spacer, and the position of perforate this moment and the distance of section bar end are shorter, and position of opening is lower.When the needs position of opening is higher, can suitably raise the section bar end when inserting makes it cross the spacer top to direct reach the furfur frame, press down spacer then, overcome the elastic reaction of spring, spacer moves down until the cutting edge plane of its upper limb and counterdie and maintains an equal level, and gets final product punching press.More preceding a kind of hole site, the hole of leaving like this is high slightly, and the difference of the two depends on the thickness of spacer, and common metal door and window (particularly aluminum alloy doors and windows) requires the two to differ 2 millimeters, so spacer thickness can be chosen 2 millimeters.

Adapt with " mould is dual-purpose " perforate, the shape centre of counterdie is high, both sides are low, are " protruding " shape, like this, could conform to the symmetrical section shape at section bar two ends, to satisfy the needs that the section bar two ends process perforate respectively.

The utility model is reasonable in design, and is easy to use, both improved work efficiency, saved material again, and a mould is dual-purpose, is particularly suitable for large-scale processing production.

Claims

1, a kind of diel, by patrix (1), counterdie (2), form towards pin (3) and furfur frame (4), be installed on patrix towards pin, the furfur frame is fixed in the counterdie rear wall, its upper end is crooked, level stretches between the upper and lower mould, it is characterized in that also being equipped with between counterdie rear wall and the furfur frame spacer (5), and its lower end contacts with spring (6).

2, diel according to claim 1 is characterized in that counterdie shape centre is high, both sides are low, is " protruding " shape.
