Problems solved by technology

In the production of extrusion dies, pipes are divided into seamed pipes and seamless pipes. Seamed pipes are produced by plane split extrusion dies. Seamed pipes have poor pressure bearing and pressure resistance due to the presence of welds.
[0003] Most of the existing aluminum alloy shunt extrusion dies cooperate with an upper die and a lower die to form products through forced extrusion by external force, but they do not have a guiding function during extrusion, and the extrusion stress area is relatively scattered, resulting in The speed of extrusion molding is slow and the molding efficiency is low

Abstract

The invention discloses a cantilever type aluminum alloy shunting extrusion die, and particularly relates to an extrusion die with a shunting guiding function and capable of accelerating the stress distribution speed of an aluminum alloy material in a lower die, so that the problems that an existing aluminum alloy extrusion die enables the aluminum alloy material to naturally flow through single extrusion and the aluminum alloy extrusion die does not have a guiding function and the shunting speed is low are solved. A top plate is fixedly connected to the top end of a stand column, a cantileverwith an upper die is arranged in front of the stand column, the two sides of the rear portion of the cantilever are arranged on a guide rod in a penetrating mode, the upper end and the lower end of the guide rod are fixed to the top plate and a supporting plate which is fixed to the lower portion of the stand column through reinforcing ribs respectively, and the lower die is fixed to the lower surface of the cantilever; and the center of the rear portion of the cantilever is connected to an extrusion assembly used for driving the cantilever to move up and down, the lower die is fixed to a workbench, four corners of the workbench are fixed at the top end of a telescopic rod sleeving the upper part of a sleeve, the lower end of the sleeve is fixed to the bottom plate, and a roller assemblyfor improving the material distribution efficiency in the lower die is arranged on one side of the bottom plate.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a cantilever type aluminum alloy split flow extrusion die. Background technique [0002] Extrusion molding is a commonly used industrial processing technology, which is often used in the processing of radiator profiles, aluminum / titanium pipes, architectural aluminum profiles, and special-shaped aluminum profiles for tools. In the production of extrusion dies, pipes are divided into seamed pipes and seamless pipes. Seamed pipes are produced by plane split extrusion dies. Seamed pipes have poor pressure bearing and pressure resistance due to the presence of welds. [0003] Most of the existing aluminum alloy shunt extrusion dies cooperate with an upper die and a lower die to form products through forced extrusion by external force, but they do not have a guiding function during extrusion, and the force-bearing area of ​​extrusion is relatively scattered, resulting in The speed...
