Self-circulation heat radiating type cutting machine

Abstract

The invention discloses a self-circulation heat radiating type cutting machine. The self-circulation heat radiating type cutting machine comprises a cutting machine main body, and the cutting machinemain body comprises a spindle box, wherein the spindle box is internally provided with a coolant which flows circularly and conducts cooling and heat radiating on a spindle and a bearing which are located in the cutting machine main body. After the above structure is adopted, compared with the prior art, the coolant can make direct contact with the heating portion in the spindle box, the heat radiating speed is increased, and the heat radiating efficiency is improved. In addition, the coolant conducts self circulation, the use amount of the coolant can be reduced, meanwhile, pollution and consumption of the coolant are decreased, and the cooling cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cutting machines, in particular to a self-circulating heat dissipation cutting machine. Background technique [0002] The cutting machine is mainly used for cutting and separating the plates during the machining process. Existing cutting machines are mainly provided with a rotatably connected main shaft in the main shaft box, on which a cutting saw blade is installed, and the main shaft is driven to rotate by a driving device, thereby driving the cutting saw blade to cut. [0003] However, during the cutting process, due to the high-speed rotation of the main shaft, the temperature of the main shaft and the bearing will be too high, which will cause the main shaft and the bearing to expand and affect the cutting accuracy. In order to solve the above-mentioned problem of excessively high temperature of the main shaft and bearings, most of the existing cutting machines open a cooling liquid flow groove on ...

Problems solved by technology

[0003] However, during the cutting process, due to the high-speed rotation of the main shaft, the temperature of the main shaft and bearings will be too high, which will cause the main shaft and bearings to expand and affect the cutting accuracy.

In order to solve the above-mentioned problem of high temperature of the main shaft and bearings, most of the existing cutting machines open a cooling liquid flow groove on the side wall of the main shaft box, and deliver the flowing cooling liquid into the cooling liquid flow groove, and absorb heat through the cooling liquid. Way to heat dissipation and cooling of the spindle box

However, in the existing cooling method, since the coolant can only circulate in the spindle box and cannot directly contact the spindle and bearings, the heat absorption effect is poor

And in order to avoid the cooling structure in the spindle box being too complicated, most of the coolant circuits adopt a straight-line type, resulting in excessive coolant consumption and increased cooling costs
