Description

Technical Field

[0002] Sawing machines are mainly applicable to metal cutting processing, and are commonly used for sawing carbon steel, deformed steel, profiles, copper and aluminum, stainless steel, die steel, alloy steel, bearing steel, ductile iron, etc. Band sawing machines cannot cut metals of any hardness. Harder materials require band saw blades with higher hardness to be sawn, otherwise the service life of the saw blades will be shortened quickly. Band sawing machines are mainly divided into two categories: horizontal and vertical, mainly judged by the sawing direction of the band saw. Those with horizontal sawing are horizontal, and those with vertical sawing are vertical. Horizontal band sawing machines are commonly used in metal processing, while vertical band sawing machines are commonly used in wood processing.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-4 , a tension adjustment structure of a sawing machine, including a workbench 1, a hydraulic rod 2 is fixedly installed on the upper part of the workbench 1, a fixed beam 3 is fixedly installed at the upper end of the hydraulic rod 2, a first mounting plate 4 is fixedly installed on the right side of the fixed beam 3, a second mounting plate 5 is fixedly installed on the left side of the fixed beam 3, a connecting plate is fixedly installed at the lower part of the second mounting plate 5, a spraying plate 6 is fixedly installed on the front surface of the connecting plate, a cleaning brush 8 is movably installed on the surface of the connecting plate, a first motor 7 is fixedly installed on the back surface of the connecting plate, a water pump 10 is fixedly installed on the upper part of the workbench 1, a water tank 9 is fixedly installed on the upper part of the workbench 1, a fixed groove is opened inside the fixed beam 3, a first lead screw 13 is movably installed inside the fixed groove, a second motor 12 is fixedly installed on the side surface of the fixed beam 3, a first moving block 14 is threadedly installed on the outer side of the first lead screw 13, and an air outlet plate 15 is fixedly installed on the surface of the first moving block 14.

[0025] Specifically, the first mounting plate 4 and the second mounting plate 5 are symmetrically distributed on both sides of the fixed beam. The upper side brush of the cleaning brush 8 is in contact with the lower part of the saw band, which can clean the saw band. At the same time, a diversion plate is provided below the cleaning bolt to facilitate the diversion of the cleaned debris and water.

[0026] Preferably, a water pipe 11 is connected to the outside of the water pump 10. The front end of the water pipe 11 is connected to the surface of the spraying plate 6, and the rear end of the water pipe 11 is connected to the inside of the water tank 9. The water outlet of the spraying plate 6 is corresponding to the upper side of the cleaning brush 8.

[0027] Specifically, the water pump 10 sucks water from the water tank 9 through the water pipe 11, and then the spraying plate 6 sprays and rinses the saw blade and the cleaning brush 8. A pressurizing device is arranged at the water outlet of the spraying plate 6 to increase the water outlet pressure, which can effectively wash away the debris.

[0028] Preferably, a blower 17 is fixedly installed on the upper part of the workbench 1. The outside of the blower 17 is communicated with an air duct 16. The upper end of the air duct 16 is communicated with the inside of the air outlet plate 15. The air outlet plate 15 is slidably connected to the surface of the fixed beam 3.

[0029] Specifically, the blower 17 makes the air outlet plate 15 blow strong wind through the air duct 16. The length of the air outlet plate 15 is the same as that of the first mounting plate 4 and the second mounting plate 5.

[0030] Working principle: When the saw blade cuts the workpiece, at the same time, the first motor 7 drives the cleaning brush 8 to rotate. The rotating cleaning brush 8 can clean the debris on the surface of the saw blade. At the same time, the water pump 10 works, and water enters the spraying plate 6 through the water pipe 11. Then the spraying plate 6 rinses the cleaning brush 8 and the saw blade, which can effectively wash away the debris, so as to effectively clean the surface of the saw blade, prevent the debris from sticking to the surface of the saw blade, and affect the cutting effect;

[0031] By starting the second motor 12, the first lead screw 13 can be driven to rotate. The first moving block 14 on the first lead screw 13 moves. The first moving block drives the air outlet plate 15 to move. The air outlet plate 15 will move back and forth on the surfaces of the first mounting plate 4 and the second mounting plate 5. At the same time, the blower 17 works. The air duct 16 is communicated with the air outlet plate 15. The air outlet plate 15 can blow the surfaces of the first mounting plate 4 and the second mounting plate 5, so as to clean the debris on the first mounting plate 4 and the second mounting plate 5;

[0032] The above structure can effectively clean the equipment and the saw blade, improve the cutting effect and efficiency, and at the same time liberate manpower, saving time and effort.

[0033] Embodiment 2:

[0034] Please refer to Figures 1-4 , an installation groove 18 is formed on the surface of the first mounting plate 4. A sliding block 19 is slidably installed on the inner wall of the installation groove 18. A moving wheel disc 20 is rotatably installed on the front surface of the sliding block 19. A fixed wheel disc 26 is rotatably installed on the surface of the second mounting plate 5.

[0035] Preferably, a fixing frame 21 is installed on the back surface of the first mounting plate 4. A second lead screw 22 is rotatably installed on the inner wall of the fixing frame 21. A second moving block 23 is threadedly installed on the outside of the second lead screw 22. A rotating rod 25 is fixedly installed on the right end of the second lead screw 22.

[0036] Preferably, the surface of the second moving block 23 is fixedly connected to the surface of the sliding block 19, and an adjusting bolt 24 is threadedly installed outside the fixing frame 21. The adjusting bolt 24 is threadedly connected to the surface of the first mounting plate 4.

[0037] Working principle: The saw band is distributed and sleeved on the moving wheel disc 20 and the fixed wheel disc 26. When the tension of the saw band becomes loose, manually rotate the rotating rod 25 clockwise. The rotating rod 25 drives the second lead screw 22 to rotate, and the second moving block 23 will drive the sliding block 19 to move to the right. The sliding block 19 slides in the installation groove 18, and the sliding block 19 will drive the moving wheel disc 20 to move, so as to tighten the saw band. On the contrary, rotate the rotating rod 25 in the reverse direction to make the moving wheel disc 20 move to the left, thereby achieving the rapid adjustment of the tension of the saw band.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit.
