Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] A combined punch of an extrusion die provided by the present invention includes a backing plate 1, a fixing plate 2, a punch base 3, a working die head 5 of the punch, bolts 4 and pins 6; the punch base 3 is fixed on the fixing plate In 2, the working die head 5 of the punch is installed in the base 3 of the punch through the bolt 4, and the bolt 4 is fixed by the pin 6 to prevent rotation.

[0015] When the punch is initially assembled, the bolt 4 is inserted into the base 3 of the punch, positioned and fixed by the pin 6, and then fixed in the fixed plate 2. The working die head 5 of the punch is built in the cavity of the punch base 3, and is screwed to the axial positioning surface of the punch base 3 by rotation. The diameter must ensure the concentricity to meet the concentricity requirements of the extrusion die for the punch and die. When the punch is extru...

Abstract

The invention discloses a combined type male die body for an extrusion die and belongs to the technical field of pressurized metal working. The combined type male die body comprises a cushion plate, a fixed plate, a male die base, a male die working die head, a bolt and a pin. The male die base is fixed in the fixed plate. The male die working die head is installed in the male die base through the bolt, and the bolt is fixed through the pin to be prevented from rotating. The male die body is of a combined structure, so that combination of the die head and the base of the extrusion male die is achieved, and extrusion is achieved through direct contact between the die head and a workpiece during male die extrusion forming. When the die head of the male die body is abraded and needs to be replaced, dismounting and mounting can be achieved quickly. By the adoption of the combined type male die body, quick replacement of the extrusion die can be achieved, production efficiency is improved, loss of the die is reduced, and cost is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of metal pressure processing, and in particular relates to a combined punch of an extrusion die. Background technique: [0002] Extrusion punch is an important working part of extrusion forming, and it is also a vulnerable part. At present, the punch structure of the extrusion die mainly has the following three structures. [0003] (1) The integral mold structure is a general structural form, simple in structure and widely used. After the punch is worn out, it needs to be replaced as a whole, and the material consumption is large. In addition, when the punch is disassembled, the fixing plate must be disassembled, which makes it inconvenient to replace the punch. [0004] (2) Mold structure with live core. The punch is an integral structure with a hollow structure in the middle. The movable mold core is assembled on the punch core, which is a mold structure with a mandrel. The mandrel of the punch is t...
