Problems solved by technology

[0004] The manufacturing process of the hair clipper blade of the above prior art has the following defects: the process of carrying out multi-process machining to the steel plate to obtain the rough blank of the hair clipper blade takes a long time, has high labor intensity, high labor cost, low production efficiency, and , the machined products have poor dimensional accuracy, and it is impossible to guarantee that all products have the same size
[0005] In addition, the quality of the blades produced by the above process, especially the degree of lubrication, is not ideal. In this way, the finished product has poor wear resistance, short service life and frequent addition of lubricating oil.

Embodiment Construction

[0028] The present invention will be further described below through specific examples, but the present invention is not limited to the following specific examples.

[0029] The manufacturing process of hair clipper blade of the present invention, it comprises the following steps:

[0030] 1. Mixing materials, uniformly mix 100 parts by weight of iron powder, 1.5 parts by weight of copper powder, 0.6 parts by weight of colloidal graphite, 0.6 parts by weight of zinc stearate lubricant, 0.02 parts by weight of machine oil and 1.5 parts of molybdenum powder. Cone mixer for mixing.

[0031] 2. Pressing and molding, using the Japanese Tamagawa powder automatic molding machine model S-100L to press, the pressing pressure is 650MPa, the pressing speed is 10 pieces / minute, and the product density after pressing can reach more than 7 grams / cubic centimeter.

[0032] 3. Sintering and quenching. The special mesh belt furnace for powder metallurgy is used for sintering and quenching. Th...

Abstract

The invention discloses a manufacturing process of a hair clipper blade, which comprises the following steps: (1) mixing materials; (2) forming the mixed materials by pressing; (3) sintering and quenching the formed product; (4) polishing the product; and (5) milling teeth at the front end of the blade. The manufacturing process of the hair clipper blade has the advantages of short time consumption, low cost, high production efficiency, small labor intensity, good product quality, high dimensional accuracy and good dimensional uniformity.

Description

technical field [0001] The invention relates to the field of hairdressing tools, in particular to a manufacturing process of a hair clipper blade. Background technique [0002] The hair clipper blade is an important part in the hair clipper. In actual use, two pieces of the hair clipper blades move in dislocation with each other, so as to trim the hair. Objectively require the hair clipper blade to have better wear resistance. [0003] The traditional hair clipper blade is a multi-process machining of alloy steel or stainless steel plate to obtain the rough blank of the hair clipper blade, and then the rough blank is quenched and polished, and finally the front part of the blade is milled out. teeth. [0004] The manufacturing process of the hair clipper blade of the above prior art has the following defects: the process of carrying out multi-process machining to the steel plate to obtain the rough blank of the hair clipper blade takes a long time, has high labor intensity...
