Description

Fine blanking die

Technical Field

The utility model relates to a mould especially relates to a fine blanking die.

Background

Stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece of a desired shape and size. Stamping and forging are the same as plastic working (or press working). Further, the blanking process can be performed, and the desired material can be separated from the plate-like base material by various methods (press, plate shearing machine, sawing machine, flame cutting, plasma cutting, laser cutting, etc.) using the press.

At present, the domestic fine blanking industry still lacks experience in the design and development aspects of complex fine blanking dies, particularly fine blanking composite forming dies, and has a larger gap with the foreign advanced level. The supply of the middle-grade and low-grade moulds is over, and the self-matching rate of the middle-grade and high-grade moulds is insufficient. In addition, compared with foreign countries, the service life of domestic moulds is generally shorter, and is generally one third of that of foreign countries.

Disclosure of Invention

This the utility model has the advantages of an advantage of providing a fine blanking die, wherein this fine blanking die is through a fundamental mode three-needle pad for the sheet material receives cushioning effect when blanking under the pressurized state of three-dimensional, makes the produced tear tape region of finished piece less, adapts to the high finished piece of size precision.

Another advantage of the present invention is to provide a fine blanking die, wherein the fine blanking die passes through the three-pin cushion of this main die for the sheet material receives cushioning effect, extension mould's life when blanking under the pressurized state of three-dimensional.

The other advantages and features of the invention will be fully apparent from the following detailed description and realized by means of the instruments and combinations particularly pointed out in the appended claims.

According to the utility model discloses an aspect, can realize aforementioned purpose and other purposes and advantage the utility model discloses a fine blanking die, include:

a main mold push pipe;

a primary mold core, wherein the primary push tube is disposed inside the primary mold core;

a main mold three-pin pad, wherein the main mold three-pin pad is arranged at one end of the main mold push tube;

a die core, wherein the die core is arranged at the other end of the main die push tube; and

and the rear through rod penetrates through the three-pin cushion of the main die and is connected to one end of the main die push tube.

Further, a main mold shell is included, wherein the main mold shell is disposed outside the main mold core.

Further, the device comprises a main die combination pad, wherein the main die combination pad is arranged on the outer side of the main die three-pin pad and the main die push tube.

Further, a master mold lock cap is included, wherein the master mold lock cap is disposed between the master mold assembly pad and the master mold shell.

Further, the rear through rod penetrates through the main die cushion block, and the main die cushion block is arranged at one end of the main die combination cushion and one end of the main die locking cover.

Further, a die housing is included, wherein the die housing is disposed outside the die core.

Further, a die pad is included, wherein the die pad is disposed at the trailing end of the die housing.

Further objects and advantages of the invention will be fully apparent from the ensuing description and drawings.

These and other objects, features and advantages of the present invention will become more fully apparent from the following detailed description, the accompanying drawings and the appended claims.
