On heat balance control of lubrication and cooling system of high speed punch
During the working process of the high-speed punch, due to the mutual friction between the crankshaft connecting rod and the bed guide rail and the motor factors, a large amount of heat will be generated, which will increase the temperature of each component of the high-speed punch and produce uneven thermal deformation. Through the previous analysis, this thermal deformation will not only affect the performance parameters of the high-speed punch, but also affect the stamping performance, dimensional accuracy The surface quality will be greatly affected, so it is of great significance for the heat balance control of high-speed punch. In addition to structural improvements, one of the most effective methods is to use a good lubrication and cooling system (above) to meet the requirements of heat balance.
High speed punch manufacturers are adopting an improved full thin oil lubrication cooling system. In this system, on the one hand, in order to stabilize the work of the high-speed punch, the system must bring enough heat from the high-speed punch. On the other hand, in order to improve and control the changing thermal convexity on the precision punch, the cooling system must do different intensity cooling according to different areas of each part of the punch. At the same time, the cooling system also acts as a lubricant, which can reduce the friction coefficient between the contact surfaces of moving parts of high-speed punch. Therefore, the lubrication cooling system is an essential part of high-speed punch. |
