A template for dismantling, cutting and positioning of the steel structure of the railway wagon car body

Abstract

The invention discloses a cutting positioning sample plate for railway wagon body steel structure dismantling. The cutting positioning sample plate is characterized by comprising a positioning plate and a cutting sample plate, wherein the right side face of the positioning plate is connected with the left side face of the cutting sample plate, the right side face of the cutting sample plate is a plane, the bottom surface of the positioning plate and the bottom surface of the cutting sample plate are on the same plane, strip-type positioning holes are formed in the positioning plate, and magnets are arranged on the cutting sample plate; the included angle between the right side face and the bottom surface of the cutting sample plate is an acute angle; the thickness of the cutting sample plate is larger than that of the positioning plate; the strip-type positioning holes are more than two in number and different in direction; the positioning plate is an aluminium plate, the cutting sample plate is a steel plate, and the positioning plate is in rivet connection with the cutting sample plate. The cutting positioning sample plate can be used for dismantling, cutting and positioning of railway wagon bodies of a variety of different models, can complete precise cutting at a time, saves gas for torque welding and cutting, lightens labor intensity, and improves production efficiency.

Description

technical field [0001] The invention relates to a positioning template, which is suitable for positioning before welding and cutting torches cut metal parts with complex structures. Background technique [0002] At present, when dismantling the steel structure of the railway freight car body, the operator first conducts a rough dismantling and cutting according to the decomposition marks, that is, quickly cuts off the parts that need to be dug up and replaced with a large-mouth cutting torch, and then sends them to the dispatcher according to the deformation of the car body. Repair station for adjustment and repair. After the adjustment and repair is completed, it is necessary to assemble the parts that have been cut out. When assembling, first stick the cut-out material or cut-off material on the cut-out or cut-off position, align and fix it by spot welding, and then perform a second fine dismantling and cutting, that is, cut with a small mouth The torch cuts off the parts...

AI Technical Summary

Problems solved by technology

Due to the large error of manual cutting, it is impossible to cut in place at one time, and a second cutting is required, which not only wastes energy but also affects production efficiency
