Here, the bottom of the working chamber is transparent, and a conveyor belt is arranged at a position opposite to the bottom of the working chamber. The debris can fall onto the conveyor belt through the bottom of the working chamber, and the chip removal device is on A motor is provided to control the operation of the conveyor belt. When removing chips, the conveyor belt on the chip removal device is controlled to operate, and the chips on the conveyor belt and located at the bottom of the working chamber are transported to the outside of the bed. A chip removal trolley can be placed at the chip removal port of the chip removal device to collect the discharged chips. In the prior art, some cutting beds also have chip removal devices, but the degree of automation is not high, and manual auxiliary cleaning is still required. For example, during the cutting process, it is inevitable that chips will fall on the clamping unit, and the chips on the clamping unit must also be cleaned, otherwise it will affect the placement of the seamless steel pipe, and even scratch the surface of the seamless steel pipe, affecting the processing yield rate.

Therefore, a cleaning device is provided on the side plate, which can absorb the chips on the clamping unit and the fixed plate, and can also clean to the bottom of the working chamber for further cleaning by the chip removal device; improve the degree of automation of cleaning chips; In the present application, the clamping unit may be a pneumatic chuck or the like, and the cutting machine may be a laser cutting machine.

[0007] Preferably, the cleaning device includes: a cleaning box, which is slidably connected between the two side plates; a dust suction device, which is fixedly connected to the cleaning box near the bottom and can remove the generated debris, and the dust suction device can be a vacuum cleaner; a cleaning brush, which is provided at the bottom of the cleaning box.

[0008] Preferably, a gear No. 1 is rotatably connected between the two side plates, a rack is fixedly connected to the surface of the cutting machine opposite to the cleaning box, and the two racks are meshed with the gear No. 1.

[0009] Preferably, a transmission box is fixedly connected to the side of the cleaning box away from the cutting machine, and a worm is rotatably connected inside the transmission box. Both ends of the worm extend to the outside of the transmission box and are fixedly connected to rollers, and the rollers correspond to the top edge positions of the bed; a worm wheel is rotatably connected inside the cleaning box, and the worm wheel meshes with the worm, and a No. 2 gear is coaxially connected below the worm wheel, the cleaning brush is rotatably connected to the cleaning box, and the top of the cleaning brush is fixedly connected to a No. 1 shaft, and the No. 1 shaft is rotatably connected to the inside of the cleaning box, and a No. 3 gear is fixedly connected to the No. 1 shaft, and the No. 2 gear meshes with the No. 3 gear.

[0010] Preferably, the pitch circle diameter of the second gear is larger than the pitch circle diameter of the third gear; and the radius of the roller is smaller than the radius of the worm.

[0011] When working, the end of the cleaning brush is provided with bristles, and the bristles are soft. When the cutting machine starts to cut the seamless steel pipe on the clamping unit from one end of the bed (this end is close to the cleaning box), when the cutting machine contacts the seamless steel pipe, the cleaning box and the cleaning brush are located higher than the cutting machine, so as to avoid the bristles of the cleaning brush interfering with the cutting machine when the cutting machine is working, and reduce the splashing debris splashing on the bristles, causing the cleaning effect of the cleaning brush to decrease; when one of the workstations is finished cutting, there are a lot of debris on this workstation; the cutting machine is controlled to move up, because the side plate The cutting machine and the cleaning box are fixedly connected with a gear, so the cutting machine moves up and the cleaning box moves down, so that the cleaning brush can contact the clamping unit, and the roller also moves down, so that its wheel surface contacts the top edge of the bed; then the moving crossbeam moves along the bed with the cutting machine and the side plate, at this time, the roller and the top of the bed move relative to each other, the roller rotates, and then the worm rotates, and the worm drives the worm wheel to rotate. Since the worm wheel is coaxially connected to the second gear below, the second gear rotates, driving the third gear to rotate, so that the first gear The shaft rotates with the cleaning brush, so when the moving crossbeam moves, the cleaning brush rotates and contacts the clamping unit (the rotating cleaning brush enhances the cleaning effect), cleaning the seamless steel pipe that has just been cut on the way, and also cleaning the corresponding clamping unit. On the one hand, it reduces the subsequent cleaning of the seamless steel pipe, and on the other hand, it cleans the debris of the clamping unit to reduce the residue of debris on the clamping unit. The cleaned debris then falls to the bottom of the working chamber for discharge by the chip removal device; at the same time, the dust collection device also works in this process, and the dust collection work is also completed during the cleaning process. , reducing the raising of debris; when the cutting machine moves to the next station, the cutting machine moves down, the cleaning box moves up, and the cutting operation continues, and so on, during the movement of the cutting machine, the debris on the clamping unit is cleaned; the pitch circle diameter of the No. 2 gear is set to be larger than the pitch circle diameter of the No. 3 gear, and the radius of the roller is smaller than the radius of the worm. According to the basic knowledge of gear transmission, this setting increases the transmission ratio of the roller to the No. 3 gear, making the rotation speed of the No. 3 gear faster, that is, the rotation speed of the cleaning brush is faster, thereby enhancing the cleaning effect of the cleaning brush.

[0012] Preferably, a nozzle is fixedly connected to the bottom of the cleaning box, and a No. 1 pipe is provided inside the cleaning box and connected to the nozzle.

On the one hand, the cleaning effect is increased due to the impact; on the other hand, the bristles are impacted to reduce debris adhering to the bristles, thereby reducing the influence of debris on the cleaning effect of the cleaning brush.

[0014] Preferably, the parts of the two side plates corresponding to the cleaning brushes are rotatably connected with rotating rollers, the rotating rollers are made of elastic material, and the connecting parts with the side plates are provided with torsion springs, and the rotating rollers are fixedly connected with a plurality of comb teeth.

[0015] During operation, when the torsion spring is in its original position, the comb teeth are in a horizontal state, and the comb teeth on the two rotating rollers can contact each other. Figure 6 As shown, when the cutting machine cuts the seamless steel pipe, the comb teeth pass through the bristles of the cleaning brush to fix the bristles and reduce the interference of the bristles with the cutting machine; when the cleaning brush moves down, the cleaning box pushes the comb teeth to rotate the rotating roller. When the side wall of the cleaning box contacts the rotating roller, the cleaning box and the rotating roller rub against each other to rotate the rotating roller. The rotating roller is made of elastic material. When the cleaning box contacts the rotating roller, it deforms, increasing the friction and making it easier to rotate. When the rotating roller rotates, the comb teeth are driven to rotate until the comb teeth are in a vertical state and close to the side plate, as shown in FIG. Figure 8 As shown, at this time, the cleaning box continues to move downward and the comb teeth are also in close contact with the side plate (the rotating roller stops rotating at this time). The comb teeth are in close contact with the side plate so that the comb teeth are stored, avoiding the comb teeth from interfering with the cleaning work; when the cleaning box moves up, that is, cleaning is completed, the cleaning box drives the rotating roller to rotate, and when the cleaning box is not in contact with the rotating roller, the comb teeth are reset under the action of the torsion spring and inserted into the bristles of the cleaning brush, and the cleaning box continues to move up (it is pre-set that the cleaning box will continue to move up after being disengaged from the rotating roller), the bristles and the comb teeth move relative to each other, and the comb teeth comb the bristles. On the one hand, this reduces the tangling of the bristles and increases the life of the bristles, and on the other hand, it combs off the debris on the bristles to ensure the cleanliness of the bristles and prepare for the next cleaning work.

[0016] Preferably, the side wall of the working chamber is arranged to be inclined, and the vertical cross-section of the fixing plate is in a herringbone shape.

[0017] During operation, the side walls of the working chamber are inclined and the vertical section of the fixed plate is in a herringbone shape. This arrangement creates an inclined surface on the side walls of the working chamber and the top of the fixed plate, reducing the residue of debris and allowing the debris to fall smoothly to the bottom of the working chamber for cleaning by the chip removal device.

[0018] The beneficial effects of the present invention are as follows: 1. The seamless steel pipe cutting table with a dust suction device described in the present invention, when one of the workstations has finished cutting, controls the cutting machine to move upward and the cleaning box to move downward, so that the cleaning brush can contact the clamping unit, and the roller also moves downward, so that the wheel surface contacts the top edge of the bed; then the moving crossbeam drives the cutting machine and the side plate to move along the bed, at this time the roller rotates, and then drives the cleaning brush to rotate through the transmission, the cleaning brush rotates and contacts the clamping unit (the rotating cleaning brush enhances the cleaning effect), cleans the seamless steel pipe just cut on the way, and also cleans the corresponding clamping unit, on the one hand reducing the subsequent cleaning of the seamless steel pipe, on the other hand cleaning the debris of the clamping unit, reducing the residue of debris on the clamping unit, the cleaned debris then falls to the bottom of the working chamber, for discharge by the chip removal device.

[0019] 2. The seamless steel pipe cutting table with a dust suction device described in the present invention has the following characteristics: when the torsion spring is in place, the comb teeth are in a horizontal state, and the comb teeth on the two rotating rollers can contact each other. When the cutting machine cuts the seamless steel pipe, the comb teeth pass through the bristles of the cleaning brush to fix the bristles, thereby reducing the floating of the bristles and interfering with the cutting machine; when the cleaning box moves up, the cleaning is completed, and the cleaning box drives the rotating roller to rotate. When the cleaning box is not in contact with the rotating roller, the comb teeth are reset under the action of the torsion spring and inserted into the bristles of the cleaning brush. The cleaning box continues to move up (it is pre-set that after the cleaning box is disengaged from the rotating roller, the cleaning box will continue to move up), and the bristles and the comb teeth move relative to each other. The comb teeth comb the bristles, which, on the one hand, reduces the tangling of the bristles and increases the life of the bristles. On the other hand, it combs off the debris on the bristles to ensure the cleanliness of the bristles and prepare for the next cleaning work. BRIEF DESCRIPTION OF THE DRAWINGS
