National standard plug support and manufacturing method thereof

Abstract

The invention relates to a method for manufacturing a national standard plug support. A straight rod raw material is adopted and horn mouth turning is performed on the tip of the straight rod raw material, then punching is performed on the horn mouth, and after punching is completed, automatic cutting is performed according to a national standard inserting sheet length requirement, thereby forming an inserting sheet blank; the inserting sheet blank is fed into a punch press stamping die to perform primary flattening and secondary flattening on the straight rod raw material, stamping edge-cutting is performed on two sides, at the same time, slots are cut on one ends of the two sides close to the horn mouth, and finally punching is performed on the head and chamfering is performed, thereby forming a molded inserting sheet; and three-angle or two-angle integral injection molding is performed on the molded inserting sheet, thereby forming the national standard plug support, one end of the national standard plug support inserting sheet is provided with the integrally formed horn mouth, the horn mouth is internally provided with a guiding circular ring line hole, the horn mouth and the inserting sheet are integrally formed, one end of a sheet body of the inserting sheet, which is close to the horn mouth is provided with symmetrical anti-falling injection molding notches at two sides. The method for manufacturing the national standard plug support improves production efficiency and quality stability, and effectively controls production cost.

Description

technical field [0001] The invention relates to a national standard plug bracket and a manufacturing method thereof. Background technique [0002] The metal inserts on the existing national standard three-plug brackets are all single-piece connected to the busbar, and the connections between the inserts and the busbar are welded or connected by screws. There are also car pins, or stamped round terminals and then riveted. The operation process is cumbersome, the cost of materials and labor is high, and the efficiency is low, so it cannot realize mass and rapid production. Contents of the invention [0003] The object of the present invention is to provide a national standard plug bracket and a manufacturing method thereof which can effectively improve production efficiency and quality stability, and effectively control production costs. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A method for manufactur...
