Causes of thermal deformation of straighteners

During the working process of the straightening machine, the rotating speed of the main shaft and the feeding speed of the equipment will be greater than the heat emitted by the heat sources such as ordinary machine tools, bearings, motors, etc. heat generated.

In this way, it can be effectively transmitted to the various parts of the machine tool through its convection, conduction and radiation, which will directly cause heating, and the equipment will directly generate its thermal expansion. The difference will directly cause the quality at each part to be different.

The heating of the internal heat source of the straightening machine is the main reason for the thermal deformation of the equipment, so the machine tool needs to effectively reduce the internal heat source during the layout process, and it is necessary to consider its hydraulic system and motor and other components as much as possible.

In the process of processing and production of the straightening machine, the chips are a heat source that cannot be ignored at all. The main reason is that if a large amount of hot cutting is not removed from the equipment in time, it will directly lead to thermal deformation of the main components of the machine tool.

The heat sources that are difficult to separate out on the leveler, such as built-in motors, screw nut pairs, bearings or other motion pairs, etc., can be directly cooled and dissipated to effectively reduce their temperature, which may reduce the temperature. its thermal deformation.

In order to effectively control the heat generated in the cutting process, most of its straightening machines and CNC lathes directly use its nozzles, and the large-flow cooling system directly sprays the cutting parts, and at the same time, it can quickly remove the hot chips. , which allows the heat to escape.
