A Synchronous Extrusion Forming Method for "h" Shape Connectors Made of Steel with Different Wall Thickness

Abstract

The invention discloses a synchronous extrusion forming method for H-shaped steel connectors different in wall thickness. The method involves a synchronous extrusion forming mold for the H-shaped steel connectors different in wall thickness. The mold comprises an upper mold assembly, a lower mold assembly and a guiding and jacking device assembly; the method includes the steps that the mold and blanks are preheated before forming, three deformation processes are conducted during extrusion of a concave-convex die, and the connectors are guided out after final forming. The method adopts a warm extrusion synchronous forming mode for achieving precision plastic forming of the H-shaped connectors different in wall thickness in order to effectively solve problems caused by existing conventionalmachining and manufacturing methods, so that the formability of alloys is improved, the comprehensive mechanical performance of the formed connectors is improved, the utilization rate of the materialsis greatly increased, the production efficiency is greatly improved, energy is saved, and emissions are reduced.
