Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cutting and cooling, and particularly relates to a hardware cutting device. Background Art
[0002] Crankshaft production is particularly critical in the hardware manufacturing process. Currently, crankshafts are typically manufactured using circular saws to cut solid carbon steel round bars as crankshaft stock. However, due to the large volume and high metal content of solid bars, frictional heat generated during cutting is significant, necessitating an effective cooling method to quickly conduct and dissipate this heat.
[0003] At present, the water cooling system has become the most commonly used cooling method for metal circular saws in the process of cutting crankshaft blanks. However, water cooling will cause contamination of the working area and the surface of the machine, which requires regular cleaning; at the same time, the use of a water cooling mechanism not only increases the complexity of operation, but also has high maintenance costs. Although air cooling is an alternative cooling method, it can provide a certain cooling effect, but when processing high heat-generating solid bars, its cooling capacity is limited and the effect is not as significant as water cooling. Therefore, the utility model provides a crankshaft cutting device, and the cooling mechanism can effectively reduce the heat generated during the cutting process. It reduces heat accumulation and avoids the pollution problem caused by water cooling; it is easy to operate and maintain, so as to reduce maintenance costs in long-term use.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the present invention are:

While maintaining a simple structure, it effectively reduces the temperature of the saw blade during the cutting process, thereby reducing saw blade wear due to overheating, extending the saw blade's service life, and improving both cutting and cooling efficiency.

The air compressor 11 body is fixed to the surface of the slide 5, and the air compressor 11 is used to provide compressed air, and the cooling gas is transported to the saw blade 8 through the first air pipe 10 and the cooling vortex tube 9; the cold end outlet of the cooling vortex tube 9 is connected to a second air pipe 13, and one end of the second air pipe 13 is connected to a universal bamboo tube 14, and the air outlet end of the universal bamboo tube 14 faces the saw blade 8.
