Abstract

The invention discloses an improved manual razor blade production method. The improved manual razor blade production method comprises the steps that S1, a steel belt is rolled and cut to form a general razor blade shape; s2, the blank is subjected to heating treatment; s3, the blank subjected to heat treatment is subjected to short-time cooling quenching; s4, the quenched blank is subjected to low-temperature treatment; s5, the blank is tempered and heated; s6, a trademark is printed on the blank obtained after tempering and heating; s7, grinding and edging; s8, the edged blade is polished; s9, the blade is cut off; s10, the quality of the blade is checked; s11, the blade is subjected to cleaning, oil removal and drying treatment; s12, the blade is subjected to ceramic micro powder cold spraying treatment; s13, a non-stick coating is sprayed on the blade, and baking and curing are conducted; s14, the blade is extracted for strength inspection; and S15, the blade is put into organic oil to be soaked and packaged, and production is completed. The cold spraying ceramic powder technology is used for replacing a traditional chromium evaporation technology, the abrasion resistance of the blade is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of manual razor production, in particular to an improved production method of manual razor blades. Background technique [0002] Manual razors generally consist of a cutter head and a hoe-shaped knife holder. The knife frame is made of aluminum, stainless steel or copper, plastic, rubber, etc. The knife head is made of blade and plastic rubber. The blade is generally made of stainless steel or carbon steel. In order to ensure the sharpness and durability of the razor, the cutting edge will be treated with special materials . In order to ensure smooth shaving, the cutter head generally contains a lubricating strip that acts as a moisturizer and calms down. When in use, the cutter head is installed on the knife holder, and the shaving can be carried out by holding the handle of the knife holder. [0003] After the traditional blade is made of stainless steel, it needs to be vapor-plated with chromium to improve the w...
