Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of shavers, in particular to a shaver head, a shaver net and a manufacturing method of the shaver net.
[ background of the invention ]
In the prior art, the shaver blade net generally comprises an outer blade net and an inner blade net which are integrally formed, and is usually manufactured by adopting a stretching process.
In order to meet the requirements of the cutter net on hardness, the material of martensitic stainless steel 420 or 440 is commonly used for manufacturing the shaver cutter net. When the integrally formed inner and outer knife net structure is manufactured, the blank needs to be stretched and formed for multiple times by using the die, the martensitic stainless steel is easy to produce cold work hardening in the multiple stretching process of the die, and cracks often appear in the knife net blank in the stretching process.
In the prior art, martensitic stainless steel with the thickness of about 0.5mm is generally used as a basic net shell to ensure that the cutter net does not deform and is safe in mechanical strength, and then the surface of a beard entering groove is machined to be about 0.12mm so as to achieve the effect of shaving beard. Therefore, the thickness of the blank needs to be processed from 0.5mm to 0.12mm on the beard feeding blade groove surface, and then the blank is processed into the beard groove, and in the case of processing into the beard groove by an electrochemical method, the processing dimensional accuracy is unstable due to the non-uniform material. The size and the processing time of an electrode for corroding a material with the thickness of 0.5mm are different from those of an electrode for corroding a material with the thickness of 0.12mm, the existing scheme is that after primary electrochemical processing, beard grooves and cutter groove cutting edges need to be repaired in a targeted mode, and the processing technology is complex.
In the prior art, a manufacturing process of a shaver net exists, and specifically, a net surface of the shaver net (namely, a part contacting with human skin, including an inner shaver net and an outer shaver net) is manufactured by using a thin material, and then the net surface of the shaver net and a net shell are welded into a whole. Although the processing technology is simplified, the whole net surface is made of thin materials, so that the whole knife net is weak in mechanical strength, namely, when a user uses excessive force in the using process, the net surface is easy to dent, the net surface is further contacted with the internal blade, and the service lives of the blade and the knife net are damaged.
