Description

Pull ring forming die

Technical Field

The patent relates to the technical field of dies, in particular to a pull ring forming die.

Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping, and is called cold stamping die (commonly called cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

But current stamping die can produce huge impact force in the in-process that uses, and the impact force directly acts on the mould to on transmitting the supporter through the mould, the supporter can produce a very strong reaction to the mould, and the supporter does not have fine buffering to the reaction of mould, leads to current stamping die to appear the problem that life is low in the in-process that uses easily.

Some products produced by using the mold have high requirements on the size of the product, such as: the O-shaped rings require higher positioning requirements when the upper die and the lower die are closed, and devices for closing and positioning the upper die and the lower die are also available. However, these devices usually use the standard guide post and guide sleeve to achieve positioning, and the tolerance caused by positioning after the tolerance of the standard guide post and guide sleeve and the tolerance of assembly are added together often does not conform to the tolerance range required by product production, so that the molded product does not conform to the size requirement or the product yield is not high.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a but accurate positioning and pull ring forming die that can accurate positioning.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the pull ring forming die comprises a positioning support, an upper die and a lower die, wherein the positioning support comprises an upper support and a lower support, the upper die is installed on the upper support, the lower die is installed on the lower support, four upper support columns are movably inserted into the four lower support columns, a positioning boss is fixedly installed on the upper die, a positioning groove matched with a guide column is installed on the upper die, and a damping base is arranged at the bottom of the lower die.

And a damping device is fixedly arranged at the bottom of the damping base.

Damping device comprises stand, backup pad and a spring, the inside of backup pad is the cavity form, and the bottom of stand runs through the backup pad and extends to the inside of backup pad, and sliding connection between stand and the backup pad, a spring winding on the stand.

And a limiting block is fixedly arranged at the bottom end of the upright post.

And a rubber pad is bonded between the damping base and the lower die.

No. two springs are arranged between the four upper support columns and the four lower support columns.

Has the advantages that: the utility model discloses a structure can realize improving the problem and the stability of the accurate location of bed die, reduces the defective rate of product dislocation, through setting up damping device, utilizes damping device to cushion the impact force when stamping die carries out the punching press to reduce the support and to the reaction force of mould, reduce the damage that the mould received, guaranteed the life of mould.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in the figure, the pull ring forming die comprises a positioning bracket, an upper die 3 and a lower die 4, wherein the positioning bracket comprises an upper bracket 1 and a lower bracket 2, the upper die 3 is arranged on the upper bracket 1, the lower die 4 is arranged on the lower bracket 2, four columns of the upper bracket 1 can be movably inserted in four columns of the lower bracket 2, a positioning boss 5 is fixedly arranged on the upper die 3, a positioning groove 6 matched with a guide column is arranged on the upper die 3, a damping base 7 is arranged at the bottom of the lower die 4, the structure of the utility model can improve the problem and the stability of the accurate positioning of the upper die 4 and the lower die 4, reduce the reject ratio of dislocation of products, and buffer the impact force when the stamping die is stamped by using the damping device through arranging the damping device, thereby reducing the reaction force of a support to the die and reducing the damage to the die, the service life of the die is ensured.

The setting of support has guaranteed that the route when mould 3 and the fit of bed die 4 can not produce the skew, and location boss 5 and positioning groove 6 have guaranteed the location between mould 3 and the bed die 4.

The bottom of the damping base 7 is fixedly provided with a damping device.

Damping device comprises stand 8, backup pad 9 and spring 10, the inside of backup pad 9 is the cavity form, and backup pad 9 is run through and extends to the inside of backup pad 9 in the bottom of stand 8, and sliding connection between stand 8 and the backup pad 9, spring 10 winding on stand 8, it has the rubber pad to bond between vibration damping mount 7 and the bed die 4.

When using, the mould carries out punching press downwards, carry out stamping forming to the object in the mould, at the in-process of punching press downwards, the mould body can extrude vibration damping mount 7, thereby make vibration damping mount 7 remove downwards, can alleviate the interact power between vibration damping mount 7 and the mould body to a certain extent through setting up the rubber pad, thereby protection vibration damping mount 7's purpose has been reached, vibration damping mount 7 receives decurrent pressure and when the lapse, can promote stand 8 and move downwards, and the effect of preliminary buffering that cooperation backup pad 9 and spring 10 reached simultaneously, the impact force of vibration damping mount 7 to backup pad 9 has been reduced.

And a second spring 12 is arranged between the four columns of the upper bracket 1 and the four columns of the lower bracket 2.

The bottom fixed mounting of stand 8 has stopper 11, prevents the stand 8 roll-off.
