Technical Field

The utility model belongs to the technical field of the stamping process, a blanking die, in particular to pneumatic control drift blanking die is related to.

Background

In the punching production, a die used for blanking is called a blanking die. The main task of the cutting die is to separate the material, on the premise that there are many different ways of sorting the cutting die. According to the process property, the blanking die can be divided into a blanking die, a punching die, a cutting die, a trimming die, a fine blanking die and the like.

The existing blanking die generally adopts the traditional blanking die, such as the patent document of application number 202110318115.5, and the patent name "blanking die", and the patent document knows that the traditional blanking die comprises an upper die mechanism, a lower die mechanism and a guide mechanism, wherein the upper die mechanism and the lower die mechanism are oppositely arranged, the guide mechanism is used for guiding the upper die mechanism to move along the blanking direction, the lower die mechanism comprises a lower die part and a stripper plate which are arranged at intervals along the blanking direction, the lower die mechanism also comprises an elastic supporting and positioning part and a first elastic supporting part which is arranged between the lower die part and the stripper plate and is used for elastically supporting the stripper plate, the second end of the elastic supporting and positioning part is used for elastically supporting and positioning the loaded sheet material, the upper die mechanism moves towards the lower die mechanism along the blanking direction to close the die and presses the sheet material on the stripper plate to be blanked, the upper die mechanism moves away from the lower die mechanism along the blanking direction to divide the die, the sheet material is forced to be ejected from the stripper plate along the blanking direction by the elastic supporting and separated from the stripper plate by the elastic supporting and positioning part,

above-mentioned blanking die utensil adopts traditional regulation formula drift, need many times location or use a plurality of mould processing when processing need many times blanking and irregularly distributed article, and the time cost is high for the poor time of location performance effect.

Disclosure of Invention

The utility model aims at providing a multistation blanking mould of numerical control cylinder's pneumatic control drift to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a multistation mould of pneumatic control drift blanking, its characterized in that, this blanking mould includes the mould, it is last backplate to go up the mould top, last backplate around be provided with connecting portion, be provided with the cylinder on the connecting portion of telling, last backplate under be provided with the die holder board, last die holder board side begin to have the clearing hole that supplies the connecting rod activity, last die holder board under be provided with punch holder board, punch holder board bottom be equipped with a plurality of and be used for the drift to the work piece that punches a hole, last die holder board on be equipped with the mounting hole of the corresponding drift cooperation installation of a plurality of confessions, and this mounting hole is linked together with the clearing hole, the drift afterbody be equipped with the bellying of positioning action, and this drift passes through the connecting rod and links to each other with the cylinder, the bottom of going up the mould is equipped with the cope match-plate pattern.

In the multi-station die for pneumatically controlling punch blanking, the plurality of punches are respectively a fixed punch and a movable punch, and the movable punches are abutted against the connecting rod to be positioned when the upper die is pressed down.

In the multi-station die for pneumatically controlling punch blanking, a lower die corresponding to the upper die is arranged below the upper die, the lower die comprises a lower back foot, and a guide sleeve guide pillar structure with a guiding function is arranged between the upper back plate and the lower back foot.

Compared with the prior art, the blanking die adopts the pneumatic control movable punch, when a blanking rule structure is needed for blanking large parts for many times, the punch can be controlled by the air cylinder to be processed without repositioning, the guide sleeve and the guide pillar on one side can be used as a backer for positioning, the guide sleeve is arranged on one side, and a large workpiece to be processed can be processed only by customizing a small die, so that the cost is reduced.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2, 3, 4, this multi-station die of pneumatic control drift 4 blanking, this blanking die include the mould, it is last backplate 1 to go up the mould top, last backplate 1 around be provided with connecting portion 9, be provided with cylinder 3 on the connecting portion 9 of telling, last backplate 1 under be provided with the die holder board, die holder board side begin to have the clearing hole that supplies connecting rod 2 activity, last die holder board under be provided with the punch plate, last punch plate bottom be equipped with a plurality of drift 4 that are used for punching a hole to the work piece, last punch plate on be equipped with a plurality of mounting holes that supply corresponding drift 4 cooperation installation, and this mounting hole is linked together with the clearing hole, 4 afterbody of drift be equipped with the bellying of effect of location, and this drift 4 links to each other with cylinder 3 through connecting rod 2, the bottom of going up the mould is equipped with cope match-plate pattern 8.
