Abstract

The invention discloses a process and equipment for bidirectional extrusion forming, comprising the following steps: bidirectionally extruding a billet, adjusting and controlling the speed of the bidirectional extrusion, so that the billet is formed into a profile with a straight line or a curved profile; The curvature is measured and fed back, and the profile is corrected to match the profile with the preset shape and size; the profile is cut to length according to the preset size. This process can effectively solve the problems of forming defects such as bending springback, wrinkling, section deformation, and cracking, break through the forming limit of existing bending forming technology, and realize the forming of thin-walled profiles with small bending radius, on-line heat treatment and precise control of curvature radius.

Description

technical field [0001] The disclosure belongs to the technical field of profile extrusion and bending forming, and in particular relates to a bidirectional extrusion forming process and equipment. Background technique [0002] Bending components refer to special structures and parts with a certain curvature made of aluminum alloys, magnesium alloys, titanium alloys, and steel and other metal materials, polymer materials, composite materials, and other non-metallic materials, such as curved wires, pipes, etc. , rods, profiles and wall panels, etc. Such components have extensive and important applications in petrochemical, aerospace, new energy vehicles, ships, high-speed rail, and construction. [0003] A two-step forming method is generally used to prepare curved components, especially curved components of metal materials. The first step is to obtain linear components by extrusion, rolling, drawing and other processes; the second step is to bend the linear components by co...
