Causes of thermal deformation of straighteners

During the work of the leveler, when the speed of the main shaft and the feed rate are higher than those of the ordinary machine tool, the heat sources such as the hydraulic system, bearing and motor on the leveler will dissipate its heat, and the tools and cutting of the equipment will be dissipated. The heat generated by the friction that directly produces relative motion with the workpiece.

The straightening machine effectively passes through various parts of the machine tool such as convection, conduction and radiation transfer, which will directly cause temperature rise, so that the equipment will generate thermal expansion. Due to the uneven distribution of heat sources in the equipment, the heat dissipation performance of the equipment will also appear. This can lead to unequal quality throughout the part.

Inconsistent temperature rise of each part of the straightening will directly produce uneven temperature field and uneven thermal expansion deformation, which will directly affect the correct relative position of the workpiece and the tool, and will directly affect its processing to a certain extent. precision.

There are many ways to reduce the thermal deformation of the straightening machine. The heat source and heat generation can be effectively controlled in the process of use. The heat generated by the internal heat source of the equipment will directly cause the thermal deformation. During the process, the internal heat source needs to be reduced.

In the process of processing and production of the straightening machine, the chips are also a heat that cannot be ignored. If a large number of hot chips in the equipment are not discharged from the machine tool in time, it will directly cause the thermal deformation of the main parts of the machine tool. .

In particular, the leveling machine has many strong cutting processes in the processing of large passes. Therefore, the worktable and spindle of the machine tool should be inclined or vertically arranged as much as possible, which is more conducive to shoulder arrangement, and an automatic shoulder arrangement device can be effectively set up.
