Cutting machine with efficient heat dissipation function

Abstract

The invention discloses a cutting machine with an efficient heat dissipation function. The cutting machine comprises a cutting machine main body, and further comprises a heat dissipation device used for dissipating heat of main shaft and bearings of the cutting machine main body through flowing cooling liquid, wherein the heat dissipation device comprises a cooling liquid conveying pipeline for conveying the cooling liquid to heating parts of the cutting machine main body; and the cooling liquid conveying pipeline comprises two or more flow dividing pipelines used for cooling two or more heating parts in a one-to-one correspondence mode, and the flow dividing pipelines are provided with valves used for matching the flow amount of the cooling liquid according to the calorific value of the heating parts. By the adoption of the structure, compared with the prior art, the cutting machine with the efficient heat dissipation function can fully cool the bearings and the main shaft, the heat dissipation speed is high, and the heat dissipation efficiency is high; and meanwhile, the cooling liquid circularly flows, so that the use amount of the cooling liquid is saved, meanwhile cooling liquid pollution and consumption are reduced, and the cooling cost is greatly saved.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a high-efficiency 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. For this reason, a method of using coolant to dissipate heat inside the cutting machine is designed. Although the use of coolant can effectively reduce the working temperature of the spindle, it i...

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.

For this reason, a method of using coolant to dissipate heat inside the cutting machine is designed. Although the use of coolant can effectively reduce the working temperature of the spindle, it ignores the cooling of the bearings. Since the bearings are mainly sealed and installed at the front and rear ends of the spindle, It is difficult for coolant to flow through the bearing to cool and dissipate it. The bearing is easy to expand and deform in a long-term high-temperature environment. In severe cases, the bearing may even be locked, resulting in damage to the spindle and motor.
