Male die and die using same

Abstract

The invention relates to a male die and a die using the same. The die comprises the male die and a female die matched with the male die for use, the male die comprises a fixed part and a work part which are arranged in a split mode, the work part is hung at the lower end of the fixed part through a hanging structure, the hanging structure comprises a dovetail groove and a dovetail protrusion matched with the dovetail groove for use, the maximum width of the dovetail protrusion is smaller than the opening width of the dovetail groove, the dovetail protrusion is inserted into the dovetail groove, and a separation-preventing block preventing the dovetail protrusion from being separated from the dovetail groove in the vertical direction is inserted in a gap between the dovetail protrusion and the dovetail grove in the extending direction of the dovetail groove. The male die is low in manufacturing cost.

Description

technical field [0001] The present invention relates to a punch used on a press and a mold using the punch. Background technique [0002] The punch can be roughly divided into two parts during use, the working part used to cooperate with the workpiece and the fixed part set on the upper end of the working part to cooperate with the mold base. The fixed part is mainly used to fix the punch on the mold On the seat, the working part is mainly used to extrude the workpiece. In the prior art, the fixed part and the working part are integrally formed, so there are many problems. For example, when the punch is used for a large press, the size and weight of the punch are also very large due to the relatively large tonnage of the press. Large, the weight of the punch often reaches several tons or even more than ten tons. Since the working part and the fixed part are integrally formed, the working part and the fixed part must be made of expensive mold steel materials, which makes the...

AI Technical Summary

Problems solved by technology

In the prior art, the fixed part and the working part are integrally formed, so there are many problems. For example, when the punch is used for a large press, the size and weight of the punch are also very large due to the relatively large tonnage of the press. Large, the weight of the punch often reaches several tons or even more than ten tons. Since the working part and the fixed part are integrally formed, the working part and the fixed part must be made of expensive mold steel materials, which makes the production cost of the punch very high; in addition , the forming of some parts requires multiple extrusion processes, and a variety of different types of punches need to be replaced on the die base. However, due to the large size and weight of each punch, a large amount of labor is required for each punch replacement. , while the efficiency of punch replacement is also very low
