The common cutting device used in the channel steel production line is a cutting machine, so as to cut the channel steel into sections.

[0003] Patent application publication number: CN110216325A, a toothless saw platform for cutting profiled steel. By adopting a movable clamping plate and a clamping push rod, the long profiled steel can be clamped flat and firmly. The saw blade of the toothless saw is pressed down by the pressing push rod, effectively avoiding the problem of uneven force when pressing down manually and causing damage to the saw blade. A sliding baffle is installed, which can adjust the length of the cut profiled steel.

The metal powder remains on the filter plate 11, and the filtered water flows to the drain pipe 12 at the bottom of the collection box 10 and is discharged, thus preventing the metal powder from floating in the air.

[0028] Refer to Figures 1-3As shown, a water tank 17 is provided at the top of the third platform 13. A water pump 18 is provided on one side of the water tank 17. A conduit 19 is provided on one side of the water pump 18. A spray head 20 is provided on one side of the conduit 19. A cutting knife 21 is provided at the top of the connecting plate 3. A protective cover 22 is provided at the top of the cutting knife 21. The cross-sections of the first platform 1 and the first platform 1 are both U-shaped. Fixed columns are provided inside the first platform 1 and the second platform 2. A rolling roller 23 is sleeved on the surface of the fixed column. The first platform 1 and the second platform 2 are used to convey the channel steel parts, and the first platform 1 and the second platform 2 can move relative to each other, so as to be applicable to channel steel parts with different arcs. The position of the adjusting plate 16 is moved back and forth by the first electric telescopic rod 15, so as to adjust the cutting distance as required.

[0029] Referring to Figures 3-4 As shown, a plurality of second electric telescopic rods 24 are provided inside the first platform 1 and the second platform 2.

[0030] Working principle of the present utility model: When the present utility model is in use, first place the channel steel part on the first platform 1, and convey the channel steel part to the second platform 2 through the rolling roller 23. Then move the channel steel part forward continuously until the channel steel part contacts the adjusting plate 16 on the third platform 13. Then start the first electric telescopic rod 15 to drive the position of the adjusting plate 16 to move back and forth, so as to adjust the cutting distance as required. And the first platform 1 and the second platform 2 can move relative to each other, so as to be applicable to channel steel parts with different arcs. Then, start the second electric telescopic rods 24 to drive the clamping plates 25 to move towards the middle, so as to clamp and fix the channel steel parts. Then the cutting knife 21 moves downward, so as to complete the cutting of the channel steel parts. At the same time, start the water pump 18.

The spray head 20 sprays the water on the cutting knife 21 to cool the cutting knife 21, reducing the damage rate of the blade and making the service life of the blade longer;

[0031] Meanwhile, the water on the cutting knife 21 flows onto the receiving plate 6. The water flowing onto the receiving plate 6 can accumulate on the receiving plate 6. When the metal powder generated during the cutting of the channel steel falls, it sinks into the water on the receiving plate 6, and the metal powder settles on the upper surface of the receiving plate 6. The water reduces the situation of the metal powder being scattered by the wind. As the water accumulating on the receiving plate 6 gradually increases, it causes the receiving plate 6 to drive the movable rod 7 to rotate, and while one end of the receiving plate 6 moves downward, the connecting spring 9 is stretched, so that the water on the receiving plate 6 flows into the collection box 10. The metal powder is filtered by the filter plate 11 inside the collection box 10, and the metal powder remains on the filter plate 11. The filtered water flows to the drain pipe 12 at the bottom of the collection box 10 and is discharged, thereby preventing the metal powder from being scattered in the air.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
