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.
