Embodiment Construction

[0056] The embodiment of the present application discloses a high-speed steel tool forging process.

[0057] refer to figure 1 , a high-speed steel tool forging process, comprising the following steps:

[0058] S1. Prepare ingredients, use a band saw to cut the high-speed steel ingot into pieces to form a billet, and the size of the billet is 20cm*20cm*15cm;

[0059] S2. Put the blank into the desktop heating furnace 1 for heating, the heating temperature is 500 °C, then increase the temperature, control the heating speed to be less than 80 °C per hour, and then keep the temperature at 850 °C, which can improve the plasticity of the blank and reduce the blank. Deformation resistance, the billet is easy to form, and good forging microstructure and mechanical properties can also be obtained.

[0060] S3. Heat the preheated billet to a temperature of 1130-1180°C, and put it into a forging die for forging to form the preliminary shape of the tool. The initial forging temperature...

Abstract

This application relates to a high-speed steel tool forging process, which relates to a tool forging process, which includes the following steps: S1, preparing ingredients, using a band saw to cut high-speed steel ingots to form blanks; S2, putting the blanks into the table Heating in the heating furnace, the heating temperature is 500°C, then increase the temperature, the heating rate is controlled at less than 80°C per hour, and then keep warm at 850°C; S3, heat the preheated billet to a temperature of 1130-1180°C, put Forging is carried out in a forging mold to form the preliminary shape of the tool. The initial forging temperature is 1100-1150°C, the final forging temperature is 900-950°C, and the stop forging temperature is 800-900°C; S4, isothermal annealing: S5, quenching: S6, back Fire: S7, using cutting and grinding tools; S8, surface treatment: in a carbon-containing atmosphere, using metal ion beams to inject high-speed steel tools, accompanied by carbonization treatment. The application has the effect of increasing the hardness, strength and wear resistance of the blank.

Description

technical field [0001] The present application relates to a tool forging process, in particular to a high-speed steel tool forging process. Background technique [0002] A tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. The vast majority of knives are machine tools, but there are also hand tools. Since the tools used in machine manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. [0003] With the development of my country's machinery industry, the cutting speed and the amount of passes are increasing in the cutting process. When the tool is cutting, due to the action of friction, the heat generated per unit time is also increasing. Sometimes the heating temperature of the blade reaches 600 ° C Above, but also under cutting pressure, prone to chipping. SUMMARY OF THE INVENTION [0004] In order to improve the problem that the tool is prone to chipping, the pres...
