Two-piece movable knife of three-ring rotary electric shaver and manufacturing method thereof

Abstract

The invention relates to a dual-workpiece moving cutter of a three-ring rotary electric shaver. The dual-workpiece moving cutter consists of a three-ring moving cutter which is molded through the punch molding of a cold-punching mold and a moving cutter driver, wherein the three-ring moving cutter is provided with a three-ring moving cutter base, three-ring moving head blades, two-ring moving head blades and a moving cutter driver connecting hole; the three-ring moving head blades, of which each is provided with three cutting heads, and the two-ring moving head blades, of which each is provided with two cutting heads, are arranged at the edge of the base through supporting feet and twisting feet; the three-ring moving head blades, the two-ring moving head blades and the moving cutter driver have the same circle center. A method for manufacturing the dual-workpiece moving cutter comprises the steps: (1) compressing an internal molecular structure of a metal raw material, so as to enable the internal molecular structure to be constant; (2) carrying out cold-punching molding; (3) carrying out heat treatment; (4) loading the moving cutter driver; (5) grinding; (6) carrying out product inspection. According to the dual-workpiece moving cutter, a four-workpiece moving cutter of the three-ring rotary electric shaver is changed into the dual-workpiece moving cutter, so that the dual-workpiece moving cutter has the advantages of fewer workpieces, lower material consumption, fewer working procedures, lower energy consumption and lower cost and is more beneficial to the production and application of electric shavers.

Description

technical field [0001] The invention relates to the technical field of electric tools, relates to the design and manufacture of a moving knife and a fixed knife net cover on a shaver unit, and relates to a double-work moving knife of a three-ring rotary electric shaver and a manufacturing method thereof. Background technique [0002] Razors are daily necessities that men use almost every day. There are various manual and electric razors, and they play an important role in the cleaning and beauty of men's faces. The current shaving appliances mainly include manual shavers taking "Gillette" as an example, reciprocating electric shavers taking "Panasonic" as an example, and single-ring and three-ring rotary electric shavers taking "Philips" as an example. razor. [0003] In the manufacture of electric shavers, the role of the knife net (including the moving knife and the fixed knife net cover) is very important. Even the moving knife of the most advanced "Philips" three-ring ...
