Abstract

The invention provides a rotating extrusion forming die for a cabin workpiece. The rotating extrusion forming die comprises a male die, a female die, an upper die assembly and a lower die base; a diecavity is formed in the female die, the die cavity can be used for placing a blank, and the female die is rotatably arranged on the lower die base about a vertical axis; the male die is arranged on the upper die assembly and can extend into the die cavity along with the upper die assembly; and the upper die assembly can drive the male die to run in the vertical direction and horizontal direction so as to carry out extrusion forming on the blank in the die cavity. According to the scheme, the cutting machining is avoided, the material utilization rate is greatly improved, the later machining consumption is reduced, then the production cost is reduced, the production efficiency is improved, the mechanical performance of a workpiece main body part is improved, the bearing capacity descendingproblem caused by flow line cutting is avoided, the deformation uniformity is improved, and the wall thickness difference is reduced.

Description

technical field [0001] The invention belongs to the technical field of extrusion molding dies, in particular to a rotary extrusion molding die for cabin workpieces. Background technique [0002] As a thin-wall load-bearing structure, special-shaped thin-walled cabin components are widely used in aerospace, civil engineering, chemical engineering, shipbuilding and other fields; in the existing plastic forming process, for special-shaped thin-walled cabin components with inconsistent wall thickness, The main part with inconsistent wall thickness cannot be formed by forward extrusion and reverse extrusion. The general forming method is: first extrude the conical cylindrical part with equal thickness, and then turn the thin-walled part; but this forming method has the following shortcoming: [0003] First, the wall thickness of the cylinder must meet the maximum molding size, wasting materials; [0004] Second, all streamlines are cut off to reduce the carrying capacity of thi...
