The direct influence of quenching process on the quality of blade of the guillotine cutter


There are many reasons to decide whether a shearing machine blade is good or bad, not only because of its good material, but also because of its processing technology to a large extent. Hardening is a major determinant in the process of processing, and it is also a process in which people judge the quality of the machine, but many people simply do not. This is a concept. Let's popularize what is called quenching.


Experienced technicians know the effect of hardening on the blade of the shears, because this stage has a great impact on the quality of the blade. A small change in temperature can cause a qualitative change in the blade, which is also the main test for those technicians, when quenching, if the temperature is higher than the design. Or it is possible to produce great changes at a low level, which has great influence on the hardness of the blade.


Hardening simple point is to use cold water treatment, temperature to change the shape of the blade after the use of cold water to fix its shape, and further deepen its hardness level, which is a relatively simple hardness interpretation, quenching treatment, generally there are three stages, need to pay attention to the three stages of temperature change The steel itself has two critical temperatures. When quenching, the temperature should be between these two temperatures, otherwise it will affect the hardness of the steel.
