Problems solved by technology

Since 3CR13 stainless steel has been heat-treated, its hardness is between HRC43-48, but the hardness is prone to cracking in the range of HRC46-48
Due to the low hardness of the material, the toughness is good, but the sharpness and wear resistance are poor.
After the blade is not sharp, the whole pair of scissors is thrown away after being sharpened several times and finally returned to the furnace. The actual use of the blade part accounts for 5% of the whole pair of scissors, resulting in a huge waste of resources and energy.

Embodiment Construction

[0013] The technical scheme adopted in the present invention is: the blade is made of expensive VG-10 Wusheng special stainless steel. According to the specifications and shapes of different civilian scissors, the blade steel accounts for 15%-25% of the overall composite knife weight; the knife body material is made of low-priced high-quality martensitic 3CR13 stainless steel, accounting for 85%-75% of the overall composite knife weight; The joint surface of VG-10 Wusheng special stainless steel and 3CR13 is sealed and wrapped in 3CR13, and subjected to high temperature and high pressure of 1180-1220 degrees to achieve metallurgical compounding. The composite material is processed into civil scissors of various specifications and shapes by die or wire cutting. .

[0014] The beneficial effects of the present invention are: (1) the service life of the original 3CR13 stainless steel civil scissors can be several times; (2) by prolonging the service life, the scarce resources of ...

Abstract

According to the technical scheme of the invention, VG-10 Takefu specially-made stainless steel (1) is adopted as blade steel, the thickness is 15%-25% of the overall thickness of a civil scissor composite, and the weight accounts for 15%-25% of the overall scissor weight; and high-quality martensite 3CR13 stainless steel (2) is adopted for a scissor body, and the combined face of the VG-10 Takefu specially-made stainless steel (1) and the high-quality martensite 3CR13 stainless steel (2) is sealed and 1180 DEG C-1220 DEG C high-temperature and high-pressure metallurgy recombination to form a scissor blank composite (3). The scissor blank composite is subjected to heat treatment, the scissor body steel hardness is HRC 43-48, and the blade steel hardness is HRC 60-62. Due to the fact that the VG-10 Takefu specially-made stainless steel only accounts for 15%-25% of the overall scissor weight, high-end civil scissors which is good in toughness, high in strength, provided with the sharp blade, resistant to rust and corrosion, high in performance, low in cost, cheap and good in quality can be produced.

Description

[0001] Technical field: [0002] The present invention relates to kitchen knives. [0003] Background technique: [0004] At present, the known civilian scissors are mainly 3CR13 high-quality martensitic stainless steel with C: 0.25-0.35, Mn: less than 1.00, Si: less than 1.00, Cr: 12.00-14.00; P and S less than 0.03 as the material for producing kitchen knives. The knife body and blade are made of a single 3CR13 stainless steel material. Since 3CR13 stainless steel has been heat-treated, its hardness is between HRC43-48, but the hardness is prone to cracking in the range of HRC46-48. Since the hardness of the material is not high, the toughness is good, but the sharpness and wear resistance are poor. After the blade is not sharp, the whole pair of scissors is thrown away after being sharpened several times and finally returned to the furnace. The actual use of the blade part accounts for 5% of the whole pair of scissors, resulting in a huge waste of resources and energy. ...
