Problems solved by technology

In production practice, the drawing process of stainless steel is the most common processing method. Stainless steel is a material that is difficult to process. Compared with ordinary carbon steel, its relative cutting performance ratio is between 0.4-0.6. The toughness of stainless steel is Large, high thermal intensity, low thermal conductivity, serious work hardening, difficult heat dissipation and many other factors, resulting in high mold temperature, severe mold wear, easy to draw, rough or break the workpiece, short mold life and low surface quality of the processed workpiece, etc. Phenomenon

The drawing process is a process with a relatively large amount of deformation, which generates a lot of heat, generally has a large oil viscosity, slow cooling speed, and is prone to high temperatures, which is more difficult than other processes. After analyzing the drawing and breaking problems, it is found that the following factors play a major role: first, the problem of lubrication, the drawing processing temperature is high, and the high temperature lubricity is not good; second, the extreme pressure performance is insufficient, and the local temperature is high during drawing processing , requires extreme pressure antiwear agent with good performance at high temperature
