Mirror knife and manufacturing process thereof

Abstract

The invention discloses a mirror knife and a manufacturing process thereof. The mirror knife comprises a mirror knife body. A knife handle connecting part is integrally arranged on one side of the mirror knife body and is composed of an inserting groove and an inserting piece. The inserting piece is inserted into a wooden knife handle, and the front end of the wooden knife handle is connected in the inserting groove in an inserted manner. Raw material annealing is adopted by the process to eliminate internal stress in steel, laser cutting forming, vacuum heat treatment and cryogenic treatmentare carried out, hardness reaches 60 HRC or above, and then structure refining, internal stress reducing, knife sharpening forming, edging, surface reinforcement, finished product assembling and otherprocedures are carried out. The high-end technology is adopted for enabling some specific metal objects to permeate into the surface of the knife, a multi-element compact surface film is formed by the metal objects and C, Cr, V and other elements in a base material, the hardness of the compact surface film reaches HV2000 or above, the anti-rust and anti-corrosion capacity is extremely high, and therefore the functions of thorough rust prevention and extreme scratching resistance are achieved, and the mirror effect is achieved; and thus, the usability and ornamental value of the knife are changed, and the effect that the use value and the artistic value of the knife are overlapped is achieved.

Description

technical field [0001] The invention belongs to the technical field of knife production, and more specifically relates to a mirror knife, and at the same time, the invention also relates to a manufacturing process of the mirror knife. Background technique [0002] Stainless steel knives have been widely used in people's production and life. With the improvement of the quality of life, people have higher and higher requirements for the performance of stainless steel. Since the knives are in contact with water or organic matter and other media for a long time in daily life, the knives are easily corroded and bacteria breed, which will affect people's health. In addition, curling or even cracks will occur during use, which will affect the use and appearance of the knives. In order to overcome the hardness problem of stainless steel, nitriding, carburizing or carbonitriding are usually carried out on stainless steel to improve the surface hardness and wear resistance of stainles...

AI Technical Summary

Problems solved by technology

Since the knives are in contact with water or organic matter and other media for a long time in daily life, the knives are easy to be corroded, bacteria, etc., which will affect people's health. In addition, curling or even gaps will occur during use, which will affect the use and appearance of the knives

In order to overcome the hardness problem of stainless steel, nitriding, carburizing or carbonitriding are usually carried out on stainless steel to improve the surface hardness and wear resistance of stainless steel. Rust also occurs in the environment, which affects the use and appearance of the tool
