Heat treatment method for tools

Abstract

The invention discloses a heat treatment method for tools. The heat treatment method for the tools comprises the following steps of preparing, fixing of the tools to be subjected to heat treatment, heat treatment and heat treatment finishing. Thus, the tools on which heat treatment is conducted are taken out of a heat treatment furnace, and the tools on which heat treatment is finished are taken; usually, small-size tools are liable to deform and fall into the heat treatment furnace after being subjected to heat treatment machining through the heat treatment furnace; however, the heat treatment method is used for fixing all the small-size tools so as to improve the strength of the integral structure, and the problem of deformation is not liable to happen in the heat treatment step; and in addition, the multiple small-size tools are fixed together, and the tools are not liable to fall and be lost in the process.

Description

technical field [0001] The invention relates to a heat treatment method, especially a tool heat treatment method suitable for small-sized tools. Background technique [0002] In the general production of hand tools, in addition to processing the hand tools to form the required hand tools, the most important thing is to perform heat treatment on the formed hand tools. The purpose of heat treatment is mainly to adjust the material of the hand tools. Hardening of the material to increase the hardness of the hand tool, so that the hand tool is not easy to deform and other problems during use, making it unusable and even affecting the work progress of the user. [0003] The steps of the existing heat treatment method are nothing more than placing the hand tool in a heat treatment furnace, and the heat treatment is mainly done by oil quenching or water quenching, so that the material of the hand tool will undergo quenching and tempering hardening during the heat treatment process,...

[0002] In the general production of hand tools, in addition to processing the hand tools to form the required hand tools, the most important thing is to perform heat treatment on the formed hand tools. The purpose of heat treatment is mainly to adjust the material of the hand tools. Harden the material to increase the hardness of the hand tools, so that the hand tools are not easy to deform and other problems during use, making them unusable and even affecting the user's work progress

[0003] The steps of the existing heat treatment method are nothing more than placing the hand tool in a heat treatment furnace, and the heat treatment is mainly done by oil quenching or water quenching, so that the material of the hand tool will undergo quenching and tempering hardening during the heat treatment process, thereby increasing The hardness of the hand tool material; however, there are many serious problems in this heat treatment method, because sometimes the size of the hand tool to be heat treated is small, and the small size of the hand tool is heat treated, due to material and structure problems, in the process of heat treatment During the process, the problem of deformation is easy to occur. Therefore, after the heat treatment, it is necessary to increase the straightening step. In this way, in addition to increasing the processing steps and reducing the processing efficiency, it also increases the cost of expenses. In addition, in the whole process During the straightening process, due to the small size of the hand tool and the increase in hardness after heat treatment, it is easy to break the hand tool during the straightening process, which undoubtedly increases the cost and work burden; When hand tools of the same size are subjected to heat treatment in a heat treatment furnace, they are often easily dropped and deposited on the bottom of the furnace because of their small size, and the hand tools dropped on the bottom of the furnace will need to wait until the heat treatment furnace is cleaned and maintained before they can be removed at one time. If it is taken out, the hand tools taken out need to be heat treated after other treatments, which will increase the burden on the cost.
