&With the rapid development of society, the use of steel punching machine is becoming more and more popular. So, do you know the measures to improve the surface cutting quality of the steel punching machine? The following is to introduce the measures to improve the surface cutting quality of steel punching machine. There are two important indexes to evaluate the cutting performance, one is the natural wear and damage degree of the cutting tool (such as cutting tool, broken tool and sticking tool). The second is the surface quality (such as corrugation, edge drop, and sticking) of the die of steel punching machine. Cutting performance is the comprehensive response of cutting tool and cutting effect, so it is difficult to quantitatively analyze the index. The influence of metal structure and matrix on the cutting performance is < br style = "list style type: none;" / > & nbsp; & nbsp; 2; In the hot working process of die steel, the metal matrix will undergo a complex phase transformation process. Only when we properly control the heating temperature of heat treatment, let the carbide particles in the metal melt into the austenite properly, and make the structure uniform and refine the grains. Because the high alloy die steel is used, it is difficult for carbide particles to melt in completely. Therefore, if the heating temperature is raised properly, the austenite will grow up, the grains will coarsen and the strength will be reduced. Also in the cooling process to properly improve the degree of supercooling, is to improve the strength of die steel. In addition, the stress at the grain boundary can be eliminated to improve the cutting quality. During cooling, a large amount of stress will be concentrated at the grain boundary, which will deform the die steel and produce great tensile and compressive stress. This stress is difficult to eliminate, which will have a great impact on the cutting surface and affect the surface finish of the workpiece. When the cutting resistance is increased in the cutting process, the effect is improved after the failure and stress relief, and the wear degree of the cutter can be reduced. < br style = "list style type: none;" / > & nbsp; & nbsp; 3. Take measures to < br style = "list style type: none;" / > & nbsp; & nbsp; high temperature treatment: as the saying goes, "high temperature cures all diseases". However, too high temperature will affect the strength of the mold. In this way, the microstructure grains will be refined and distributed more evenly, thus providing the mechanical strength of the microstructure metal. Tissue stress relief: This is the key. If we don't take measures to eliminate the stress in time, the die steel will crack and deform. < br style = "list style type: none;" / > & nbsp; & nbsp; the above contents are the measures to improve the surface cutting quality of the steel strip punching machine die.
