Description

Technical Field

[0001] The utility model relates to the technical field of sawing machines, and more specifically to a cooling mechanism of a sawing machine. Background Art

[0002] Band saws are machine tools used for sawing various metal materials. They are divided into horizontal and vertical types according to their structure; they are divided into semi-automatic, fully automatic, and CNC types according to their functions. The horizontal type can be divided into double-column and scissor-type. Usually, the saw blade will generate high temperature during the use of the band saw, and the saw blade needs to be cooled.

[0003] After searching, the utility model patent with announcement number CN217529450U discloses a cooling mechanism for a double-column horizontal band sawing machine. The device is provided with a processing table, on which a sawing machine body can be raised and lowered, and a band saw blade is installed on the sawing machine body. The band saw blade has a cutting part located above the workpiece to be processed, and the cutting part can move along a first direction to cut the workpiece to be processed, and the first direction is parallel to the processing table; a cooling device is installed at the bottom of the sawing machine body, including a heat dissipation fan and a nozzle assembly arranged along the first direction, the heat dissipation fan is used to dissipate heat from the cutting part, and the nozzle assembly includes nozzles arranged on both sides of the cutting part along a second direction, the second direction is parallel to the processing table and perpendicular to the first direction, and the nozzle is connected to a water supply device; through the above structure, the heat dissipation fan and the nozzle assembly are used to cool the cutting part, so as to achieve a double cooling effect and improve the cooling efficiency.

[0004] However, the above patent has the following shortcomings: it is not convenient to cool the water in the water tank. When the cooled refluxed water enters the water tank, it will cause the water temperature in the water tank to rise, affecting the subsequent cooling effect of the sawing machine; in addition, when the ambient temperature around the sawing machine is high, the wind blown by the cooling fan also has a high temperature, which has a poor effect on cooling the saw blade. For this reason, we propose a cooling mechanism for the sawing machine. Utility Model Content
