Diversion extrusion die for fine cantilever structure

Abstract

The invention provides a diversion extrusion die for a fine cantilever structure. The diversion extrusion die comprises an upper die body and a lower die body which are matched with each other. The upper die body is provided with diversion holes and diversion bridges. The diversion bridges partition the diversion holes. A die core is further arranged in the center of the inner side of the upper die body. A welding-on chamber is arranged on the lower die body. A cavity consistent with a machined aluminum profile in outline is formed in the center of the welding-on chamber. After the die core is inserted in the cavity, a mold cavity consistent with the aluminum profile in shape is formed. The cantilever structure is connected to one side wall of the cavity and located at the included angle position of the two side walls of the cavity. The cantilever structure comprises a cantilever neck and a cylindrical cantilever head which are connected. The cantilever neck is connected with one side wall. A protruding overhanging type suspension bridge is machined on the bottom face of the welding-on chamber beside the cavity, one end of the suspension bridge and the cantilever head are connected and fixed, and the suspension bridge extends towards the inner side wall of the welding-on chamber in the cantilever neck direction. The diversion extrusion die solves the problem that in the prior art, a fine cantilever structure of an extrusion die is prone to being extruded and broken, and consequently the die cannot be used.

Description

technical field [0001] The invention relates to the field of die design and processing, in particular to an aluminum extrusion die with a cantilever structure. Background technique [0002] Aluminum profile products with a cantilever structure refer to profile products that constitute a semi-closed shape. The die that processes this product forms a loaded cantilever beam during the extrusion process, which is called a cantilever die. Because the pressure exerted by the extruder usually reaches hundreds of tons or even thousands of tons, the strength requirements for the mold are very high. [0003] Existing cantilever aluminum profiles designed for aviation seat frames, the aluminum profiles are in the shape of a "day" (as attached figure 1 As shown), a circular ring with an opening facing outward is processed on one corner of the "日"-shaped aluminum profile. The ring is used to pass through the core of the backrest curtain, and the opening is used to clamp the backrest c...
