Description

A combined punching die

technical field

The utility model relates to a combination punching die.

Background technique

Construction pipe piles are basic components widely used in high-rise buildings, highways, etc. The pipe pile end plates are the steel connecting end plates at both ends of the construction pipe piles. During the production of pipe pile end plates, the workpiece needs to be punched. Existing The combined punching die usually stamps one hole at a time. After punching one hole, the workpiece needs to be rotated, and then the next hole is punched, which will cause problems such as complicated process and long production cycle.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a combination punching die with simple structure, which is used for punching holes on the end plates of pipe piles and can punch multiple holes at one time.

In order to achieve the above object, the utility model adopts the following scheme:

A combination punching die is characterized in that it includes a lower base plate, on which a lower positioning die plate is arranged, and on the lower positioning die plate, a plurality of lower punching dies are evenly distributed annularly, and on the described lower base plate A stripper plate is movably arranged on the lower positioning die plate, a stamping through hole corresponding to the lower punching die is provided on the stripper plate, a guide rod is provided on the lower bottom plate, and a guide rod is provided on the bottom plate. The upper bottom of the punching die is sleeved on the guide rod of the punching die, and an upper positioning die plate is arranged on the upper base of the punching die, and a plurality of upper punching dies corresponding to the lower punching dies are arranged on the upper positioning die plate.

A combined punching die as described above is characterized in that an annular groove is provided on the lower positioning die plate, and the lower punching dies are evenly distributed in the annular groove, and the A plurality of positioning pins are arranged outside the groove, and a plurality of positioning holes are arranged on the stripper plate, and the positioning pins are arranged in the positioning holes.

In summary, the utility model has the beneficial effects relative to the prior art as follows:

In the utility model, a plurality of lower punching dies are uniformly distributed in a ring on the lower positioning die plate, and a plurality of upper punching dies corresponding to the lower punching dies are arranged on the upper positioning die plate. Under the action of the upper punching die, the pipe pile end plate workpiece on the lower punching die punches out a plurality of set holes at one time, with simple operation and high production efficiency.
