Abstract

The invention discloses a square three-way two-stage forming die and a forming process. A staged extrusion forming mode is adopted, a cylindrical pre-forged blank is extruded into a cylindrical blankthrough a first set of die, and then the cylindrical blank is extruded into a square three-way piece in multiple directions through a second set of die. Compared with the prior art, the problems thatthe square three-way piece is difficult to extrude and form and easy to fold, wrinkle and the like are solved, meanwhile, the tonnage requirement of equipment can be greatly reduced, and the tonnage required by two-stage extrusion forming of the square three-way piece can be reduced by about 30 percent compared with one-time multi-direction extrusion forming of the square three-way piece.

Description

technical field [0001] The invention relates to the technical field of extrusion forming, in particular to a square tee two-stage forming die and a forming process. Background technique [0002] Multi-directional extrusion molding refers to the process of simultaneously or sequentially pressing in the axial and lateral directions to form cavity-type complex structural parts in different directions. The multi-directional extrusion process uses two or three hydraulic cylinders of the hydraulic press to drive the mold to perform independent and coordinated movements in different directions perpendicular to each other to cause large plastic deformation of the workpiece to obtain the desired workpiece. The material is subjected to multi-directional pressure during the multi-directional extrusion plastic deformation process. The produced forging has a dense structure, which can close the internal defects of the raw material, and at the same time ensure the integrity of the metal s...
