End corner post molding process of track vehicle

Abstract

The invention relates to an end corner post molding process of a track vehicle. The process comprises the steps of obtaining a strip-shaped main material panel by utilizing a laser cutter for cutting and blanking; cutting a first supplement plate and a second supplement plate, with radian at side edges, by the laser cutter; bending the main material panel to form an end corner post with an W-shaped section by a bending machine; bending the middle lower part of the end corner post in a simmering mode to form a bending part consistent with a vehicle body drum shape in angle; bending a first plate and a second plate at the upper part of the end corner post to form the arc connected with a vehicle top; and welding the first and second supplement plates. The process analysis is performed according to design paper, the scheme combining the bending, the simmering and additionally welding the supplement plates is made; the end corner post quality is greatly improved by technological innovation, all sizes are controlled, the demands of paper and assembly are met, the quality and work efficiency are improved, the cost is reduced, the manufacturing process for forming a complicated workpiece is realized and the experience is accumulated for later forming of the complicated workpiece.

Description

Technical field [0001] The invention relates to a forming process for an end corner post of a rail vehicle, and belongs to the technical field of end corner post forming. Background technique [0002] The end corner column is an important bearing part in rail vehicles, with complex shapes and difficult overall formation. In order to achieve higher strength and rigidity, the end corner column is designed to be (cross-section) W-shaped, which can meet the performance requirements, but its overall formation is difficult, and it is easy to cause wrinkles and cracks in the deformation. Repeated process tests have proved that it cannot be obtained from The whole process is realized. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a rail vehicle end corner post forming process. [0004] In order to solve the above technical problems, the rail vehicle end corner post ...
