Problems solved by technology

Therefore, when manufacturing heavy-duty and medium-sized extrusions, the outer diameter of the prestressed extrusion system needs to be made very large, and it is difficult to implement. Its size is large, the versatility is poor, and the cost of the mold is too high

Abstract

The invention discloses a follow-up pre-stress split die extruding system and a follow-up pre-stress split die extruding method. The system can comprise a core cylinder, a core cylinder supporting body and a supporting force applying device, wherein the core cylinder is formed to be suitable for being molded in an extruding way; the core cylinder supporting body is circumferentially arranged around the core cylinder so as to support the core cylinder; the supporting force applying device applies a first action force (P1) to the core cylinder supporting body; and the first action force (P1) is controlled in a follow-up way on the basis of a second action force (P2) extruded in the core cylinder and applied to the inner circumferential side wall of the core cylinder. According to the follow-up pre-stress split die extruding system provided by the embodiment of the invention, the first action force P1 is changed along with the change of the second action force P2, and a pre-tightening layer is not required to be arranged on the outer wall of the core cylinder, so that the size of follow-up pre-stress split die extruding system is reduced, and the manufacturing cost of the follow-up pre-stress split die extruding system is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic forming, in particular to a follow-up prestressed split-die extrusion system and method. Background technique [0002] The metal extrusion process is an advanced process of plastic forming, and the extrusion process needs to be implemented in the extrusion system. The design and manufacture of extrusion systems is of great significance for high-temperature extrusion, warm extrusion and cold extrusion of heavy ferrous and non-ferrous metals. The extrusion system in engineering is divided into two categories: prestressed extrusion system and non-prestressed extrusion system. The existing non-prestressed extrusion system has a small strength utilization factor. difficulty. The existing prestressed extrusion system needs to apply prestress to the extrusion system in advance, and a preloaded layer needs to be set. Therefore, the core barrel of the extrusion system must have a certain thickness to pre...
