Precise extrusion forming die for complex special-shaped thin-wall aluminum alloy

Abstract

The invention discloses a precise extrusion forming die for a complex special-shaped thin-wall aluminum alloy. The precise extrusion forming die comprises an upper die and a lower die. According to the precise extrusion forming die for the complex special-shaped thin-wall aluminum alloy, the upper die body, the lower die body, the die sleeve, the first counter bores, the first threaded holes and the first fixing bolts are used in cooperation, so that the upper die body and the lower die body can be fixed to each other; and meanwhile, the upper die and the lower die are further fixed through cooperation of a fixing clamp, an avoiding groove, a second counter bore, a second fixing bolt, a nut, a clamping piece and a clamping groove, so that the upper die and the lower die are fixed more firmly, and the possibility that the upper die and the lower die crack is reduced. And through the arrangement of the connecting rod, the strength of the opening of the U-shaped die holder is improved. Through cooperative use of the sliding grooves, the limiting grooves, the inserting plates, the limiting strips, the threaded sleeves, the threaded rods, the rotating handles, the pressing blocks and the containing grooves, the upper mold and the lower mold which are placed in the U-shaped mold base can be conveniently fixed through the pressing blocks by rotating the rotating handles.

Description

technical field [0001] The invention relates to an extrusion forming die, in particular to a precision extrusion forming die for complex special-shaped thin-walled aluminum alloys. Background technique [0002] Aluminum alloy extrusion is a plastic processing method that applies external force to the metal billet placed in the container (extrusion cylinder) to make it flow out from a specific die hole to obtain the desired cross-sectional shape and size. The extrusion die is usually composed of a die body, a die sleeve, a die pad and a die base. The die body usually includes an upper die and a lower die, so that complex special-shaped thin-walled aluminum alloy profiles can be extruded. [0003] However, at present, the traditional precision extrusion forming die for complex special-shaped thin-walled aluminum alloys on the market, the fixed connection between the upper die and the lower die is usually only fixed by bolts on the upper die and the lower die through the die sl...

Problems solved by technology

[0003] However, in the traditional precision extrusion molds for complex special-shaped thin-walled aluminum alloys currently on the market, the fixed connection between the upper mold and the lower mold is usually only fixed by the upper mold and the lower mold with bolts through the mold sleeve, and there is a problem that the fixation is not firm enough. question
