Reshaping die of urban rail vehicle door corner part

Abstract

The invention provides a reshaping die of a door corner part. The reshaping die is used for reshaping an urban rail vehicle door corner part. The reshaping die of the door corner part comprises a lower die plate, an upper die plate, a guide column, a guide sleeve, a convex die, a concave die, a fixed wedge block, a sliding wedge block, a side compressing block and a door corner, wherein a groove is formed in the lower die plate and can reshape the door corner part arranged at a door corner, the plane of the fixed wedge block is in contact with the side compressing block when the door corner part reshaping die is closed and the fixed wedge block goes down, the oblique plane is in contact with the sliding wedge block, and the side compressing block is fixed, so that the fixed wedge block pushes the sliding wedge block to slide towards the concave die and clamp the door corner. Compared with the prior art, the door corner part reshaping die effectively overcomes the two defects of poor planeness and large 90-degree angle resilience occurred in door corner stamping formation, the defect problem which cannot be solved by adopting a traditional door corner reshaping method is eliminated,the product quality and precision of door corners can be effectively improved, and accordingly the forming precision of like members is remarkably improved.

Description

technical field [0001] The invention belongs to the field of shaping mold devices for door corner pieces of urban rail vehicles, and in particular relates to a shaping mold for door corner pieces of urban rail vehicles. Background technique [0002] The front view of the upper left door corner 1 of the urban rail vehicle is as follows figure 1 As shown, the plane of the door corner 1 includes two long straight sides a, b. The two end surfaces of the door angle 1 have side walls, the width of the end surface 101 is c, and the width of the end surface 102 is d. The corner of the door angle 1 is composed of two short straight sides and a 90° arc R1. Viewed from direction A, end face 11 is as figure 2 As shown, the height of the door angle is h, the thickness of the sheet is t, the plane and the side wall form 90°, and the arc of the joint is R2. Viewed from the B direction, the end face 12 is as image 3 As shown, there is a chamfer at the connection between the plane and ...
