Description

[0002] In the production and manufacturing process of metal doors and windows, in order to ensure that the product meets the design requirements and accuracy, the metal material of the door and window usually needs to be accurately cut, and the metal material is segmented and trimmed by the blade. The performance of the cutting blade and the sharpness of the blade edge directly affect the quality and accuracy of cutting.

[0003] However, when the cutting blade works continuously under high load conditions, the friction between the blade and the metal material will generate a large amount of heat. If this heat cannot be effectively dissipated in time, the temperature of the blade will continue to rise. The increase of the blade temperature not only affects the hardness and cutting performance of the blade, but also may cause the material of the blade to deform or wear out.

[0004] More seriously, when the blade temperature is too high, the heat generated during the cutting process will directly affect the cutting quality. The specific performance is that the cutting surface is uneven, the cutting trace is uneven, and even burrs or deformation problems occur, which may cause the cutting position to deviate seriously, and cannot meet the strict production accuracy requirements. If this situation is not solved in time, it will lead to a decrease in production efficiency and the product quality cannot meet the standard, thereby affecting the normal operation of the entire production line and may increase the difficulty and cost of later processing.
