Description

Punch head structure for stamping die

Technical Field

The utility model relates to the technical field of punches, in particular to a punch head structure for a stamping die.

Background

A punch is a part of a stamping die, which is a tool used to impact or cut a metal material. The punch is typically made of a hard material such as high speed steel, cemented carbide, or the like. The shape and size of the punch are designed according to the required stamping shape, and can be round, square, elliptic and the like.

The punch is used for applying impact force to the metal material in the stamping process so as to enable the metal material to be plastically deformed or cut. The portion of the punch in contact with the metal material is called the punch, the shape and size of which determines the shape and size of the final workpiece. The punch is usually moved relative to the metal material by the movement of a punch press or a punch press, thereby effecting the impact or cutting of the metal material.

At present, the punch is in the in-process of punching the processing material, and the material that is punched can bear the force of punch and its high-speed striking to cause the material to take place vibrations in the twinkling of an eye of punching, this can cause the material that is punched to take place the displacement, leads to punching a hole to take place the skew, and the in-process that the material shakes can exert the shearing force to the punch simultaneously, causes the damage to the punch.

Therefore, it is necessary to solve the above problems by inventing a punch head structure for a press die.

Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

The utility model provides a punch head structure for a stamping die as shown in figures 1-4, which comprises a punch 1, wherein a pressing cylinder 2 is sleeved at the lower end part of the punch 1, guide grooves 4 are formed in the two sides of the punch 1 and above the lower end part, clamping blocks 5 are arranged on the inner walls of the two sides of the pressing cylinder 2 and correspond to the guide grooves 4 on the two sides of the punch 1, the clamping blocks 5 are matched with the guide grooves 4 and are in sliding connection, and a cushion block 3 is fixedly arranged at the bottom of the pressing cylinder 2.

Further, in the above technical scheme, screw holes 8 are formed in two sides above the pressing cylinder 2, jackscrews 6 are mounted in each screw hole 8 in a threaded manner, the front end of each jackscrew 6 penetrates through the inner wall of the pressing cylinder 2 and is fixedly connected with the outer side of the corresponding clamping block 5, the clamping block 5 is fixed at the position of the inner wall of the pressing cylinder 2 through the jackscrews 6, and meanwhile the clamping block 5 is convenient to detach.

Furthermore, in the above technical scheme, springs 7 are vertically installed at four corners of the upper end of the cushion block 3, and the cushion block 3 is made of rubber materials, so that the friction force between the bottom of the cushion block 3 and the material needing to be punched is improved.
