Problems solved by technology

[0002] The traditional production method of the hinge is mainly produced by arc welding. It first hollows out the middle part of one side of the iron plate, and then bends the two sides of the hollow into inner holes respectively. Then, it adopts arc welding. The joint between the bent end and the iron plate is welded or cast through a mold; the welded hinge is mainly arc welded, and arc welding is not only low in work efficiency, but also highly destructive to the environment; The page needs to introduce molten metal into the mold cavity, which not only consumes high energy, but also pollutes the environment

Abstract

The invention provides a hinge electric resistance welding process. A hinge comprises a hinge piece and a shaft sleeve which is assembled with the hinge piece, the shaft sleeve is formed by cutting asteel pipe, and the hinge piece is formed by cutting a steel strip or a steel plate. The hinge is manufactured by accurately positioning the hinge piece and the shaft sleeve and then welding the hingepiece and the shaft sleeve through a resistance welding process, and the electric resistance welding process is controlled by an electric resistance welding system. The electric resistance welding system comprises a shaft sleeve positioning tool system and a hinge piece positioning tool system, the hinge piece positioning tool system comprises a reference electrode and a hinge piece limiting andfixing electrode, and the shaft sleeve positioning tool system comprises a shaft sleeve positioning shaft and a shaft sleeve limiting and fixing electrode. According to the hinge electric resistance process, the traditional production process of the hinge is innovated, the production process of the hinge is simplified, the production efficiency of the hinge is high, the production time is short, the use of arc welding is avoided, and the phenomenon that the environment is polluted or the environment is damaged is avoided; and the process is environment-friendly, convenient, rapid and simple touse, low in cost, and uniform and full in welding spots of welding joints.

Description

Technical field [0001] The invention relates to a hinge resistance welding process. Background technique [0002] The traditional production method of hinges is mainly produced by arc welding. Firstly, the middle part of one side of the iron plate is hollowed out, and then the hollowed out two sides are respectively rolled into inner holes, and then arc welding is adopted. The joint between the end of the coil and the iron plate is welded or cast through a mold; the welding hinge is mainly arc welding, which not only has low efficiency, but also has a strong destructive effect on the environment; It is necessary to introduce molten metal into the mold cavity, which not only consumes high energy, but also pollutes the environment. The invention innovates the traditional production technology of the hinge, and makes the production of the hinge not only simpler, but also very environmentally friendly, without pollution to the environment, and low cost. Summary of the invention [0...
