TECHNICAL FIELD

[0001] The present application belongs to the technical field of seamless steel pipe cutting, in particular to a seamless steel pipe cutting table with a dust collection device. BACKGROUND

[0002] The seamless steel pipe is a long strip steel material with a hollow section and no joint on the periphery, which is widely used in many fields.

[0003] In the production and processing of seamless steel pipes, cutting is indispensable. During the cutting process, a large amount of debris will be generated, which needs to be cleaned. In the prior art, manual cleaning is usually required. Of course, some cutting beds can also automatically clean, that is, a chip removal device is provided, but the degree of automation is not high, and manual assistance is still required for cleaning. For example, during the cutting process, it is inevitable that debris will fall on the clamping unit. The debris on the clamping unit also needs to 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. At this time, when cleaning the debris on the clamping unit, a high-pressure air gun, a high-pressure water gun or manual cleaning of the debris on the clamping unit is required, which is not highly automated and affects work efficiency.

[0004] In view of this, the present application provides a seamless steel pipe cutting table with a dust collection device to solve the above technical problems. SUMMARY

[0005] In order to make up for the shortcomings of the prior art and improve the degree of automation of the cutting bed in cleaning debris, the present application provides a seamless steel pipe cutting table with a dust collection device.

[0006] The technical scheme adopted by the present application to solve its technical problems is: a seamless steel pipe cutting table with a dust collection device, comprising: a cutting bed, the cutting bed comprising: a bed body, a working cavity is formed in the bed body, a plurality of fixed plates are fixedly connected to the side wall of the working cavity, a clamping unit is arranged on each fixed plate; a chip removal device, the end of the bed body is provided with a chip removal device, the chip removal device is provided with a conveyor belt, the bottom of the working cavity is through and opposite to the conveyor belt, the chip removal device can transport the debris falling on the conveyor belt from the bottom of the working cavity to the outside of the bed body; a moving cross beam; the bed body is provided with a moving cross beam; a moving block; the moving cross beam is provided with a moving block, the two sides of the moving block are fixedly connected with side plates; a cutting machine, the moving block is provided with a cutting machine, the cutting machine is in sliding connection with the side plates; a cleaning device, the side plates are provided with a cleaning device, the cleaning device can suck and remove the debris on the clamping unit and the fixed plate, and can also clean to the bottom of the working cavity for further cleaning by the chip removal device.

[0007] In operation, the moving beam can move back and forth along the bed body (the control mode can be a screw nut pair, and specific details can be referred to the prior art), the moving block can move back and forth on the moving beam (the control mode can be a screw nut pair, and specific details can be referred to the prior art), and the cutting machine can move up and down on the moving block (the control mode can be a screw nut pair, a conveyor belt, etc., and specific details can be referred to the prior art). In the present application, there are multiple workstations, i.e., multiple seamless steel pipes can be placed on the multiple workstations. The moving beam, the moving block, and the cutting machine control the back-and-forth and up-and-down movement of the cutting machine, and then cut the multiple seamless steel pipes. In the cutting process, debris will inevitably be generated. In the present application, the clamping unit is arranged on the fixed plate, and the fixed plate is fixedly connected to the side wall of the working cavity. Therefore, the debris falls to the bottom of the working cavity, and then is transported to the outside of the bed body by the debris removal device. The bottom of the working cavity is transparent, and the part opposite to the bottom of the working cavity is provided with a conveyor belt. The debris can fall to the conveyor belt through the bottom of the working cavity. The debris removal device is provided with a motor for controlling the operation of the conveyor belt. In the debris removal process, the conveyor belt on the debris removal device is controlled to operate, and the debris on the conveyor belt and located at the bottom of the working cavity is transported to the outside of the bed body. A debris removal trolley can be placed at the debris removal opening of the debris removal device for collecting the removed debris. In the prior art, some cutting machines also have a debris removal device, but the degree of automation is not high, and manual assistance is still required for cleaning. For example, during the cutting process, debris will inevitably fall on the clamping unit. The debris on the clamping unit also needs to 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. At this time, the debris on the clamping unit is cleaned by using a high-pressure air gun, a high-pressure water gun, or manually. The degree of automation is not high, and the working efficiency is affected. Therefore, the cleaning device is arranged on the side plate. The cleaning device can suck and remove the debris on the clamping unit and the fixed plate, and can also clean the bottom of the working cavity for further cleaning by the debris removal device. The degree of automation for cleaning debris is improved.

[0008] In the present application, the clamping unit can be a pneumatic chuck, and the cutting machine can be a laser cutting machine.

[0009] Preferably, the cleaning device comprises a cleaning box, which is slidingly connected between the two side plates; a dust collection device, which is fixedly connected to the position close to the bottom of the cleaning box; the dust collection device can suck and remove the generated debris, and can be a dust collector; and a cleaning brush, which is arranged at the bottom of the cleaning box.

[0010] Preferably, a gear is rotatably connected between the two side plates, and the cutting machine and the cleaning box are fixedly connected with a rack. The two racks are engaged with the gear.

[0011] Preferably, the cleaning box is fixedly connected with a transmission box away from one side of the cutting machine, a worm is rotatably connected in the transmission box, the both ends of the worm extend to the outside of the transmission box and are fixedly connected with rollers corresponding to the position of the top edge of the bed body, a worm wheel is rotatably connected in the cleaning box, the worm wheel is engaged with the worm, a second gear is coaxially connected below the worm wheel, the cleaning brush is rotatably connected with the cleaning box, a first shaft is fixedly connected to the top of the cleaning brush, the first shaft is rotatably connected with the cleaning box, a third gear is fixedly connected to the first shaft, and the second gear is engaged with the third gear.

[0012] Preferably, the pitch circle diameter of the second gear is greater than the pitch circle diameter of the third gear, and the radius of the roller is smaller than the radius of the worm.

[0013] When working, the end of the cleaning brush is provided with soft bristles. When the cutting machine starts cutting the seamless steel pipe on the clamping unit from one end of the bed (the end close to the cleaning box), the cleaning box and the cleaning brush are higher than the cutting machine when the cutting machine contacts the seamless steel pipe, so as to avoid the bristles of the cleaning brush interfering with the cutting machine when the cutting machine works, and to reduce the splashing of the debris on the bristles, thereby reducing the cleaning effect of the cleaning brush. When cutting is completed at one station, there are a lot of debris on the station. The cutting machine is controlled to move upward. Since the side plates are rotationally connected with the first gear, the cutting machine is fixedly connected with the rack on the opposite side of the cleaning box, so that the cutting machine moves upward and the cleaning box moves 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 beam moves along the bed with the cutting machine and the side plates. At this time, the roller moves relative to the top of the bed, the roller rotates, and the worm rotates, thereby driving the worm gear to rotate. Since the second gear is coaxially connected below the worm gear, the second gear rotates, thereby driving the third gear to rotate, and thereby driving the first shaft with the cleaning brush to rotate. Therefore, when the moving beam moves, the cleaning brush rotates and contacts the clamping unit (the rotating cleaning brush enhances the cleaning effect), thereby cleaning the seamless steel pipe that has just been cut and 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 on the clamping unit, reduces the residue of the debris on the clamping unit, and the cleaned debris falls to the bottom of the working cavity for the debris discharge device to discharge. At the same time, the dust collection device also works in the cleaning process, thereby reducing the lifting of the debris. When the cutting machine moves to the next station, the cutting machine moves downward, the cleaning box moves upward, and the cutting operation is continued. In this way, the debris on the clamping unit is cleaned during the movement of the cutting machine. The pitch circle diameter of the second gear is greater than the pitch circle diameter of the third 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 and the third gear, so that the rotating speed of the third gear is faster, that is, the rotating speed of the cleaning brush is faster, thereby enhancing the cleaning effect of the cleaning brush.

[0014] Preferably, the bottom of the cleaning box is fixedly connected with a spray head, and the cleaning box is internally provided with a first pipeline connected with the spray head.

[0015] When it is necessary to enhance the cleaning effect of the cleaning box during work, a high-pressure gas pipe or a cutting fluid pipe can be connected to the top of the cleaning box. The spray head sprays high-pressure gas or cutting fluid through the first pipeline, thereby increasing the cleaning effect due to the impact effect, and reducing the influence of the debris on the cleaning effect of the cleaning brush by impacting the bristles.

[0016] Preferably, two side plates are rotatably connected with rotating rollers at positions corresponding to the cleaning brush, the rotating rollers are made of elastic material, and torsion springs are arranged at the connecting positions of the rotating rollers and the side plates, and a plurality of comb teeth are fixedly connected to the rotating rollers.

[0017] When the torsion springs are in the original position, the comb teeth are in a horizontal state, and the comb teeth on the two rotating rollers can contact each other, as shown in FIG. 6. Figure 6 When the cutting machine cuts the seamless steel pipe, the comb teeth pass through the bristles of the cleaning brush, fix the bristles, and reduce the interference of the bristles on the cutting machine; when the cleaning box moves downward, the comb teeth are pushed by the cleaning box, the rotating rollers rotate, and when the side wall of the cleaning box contacts the rotating rollers, the cleaning box and the rotating rollers rub against each other, the rotating rollers rotate, the rotating rollers are made of elastic material, and the rotating rollers deform when the cleaning box contacts the rotating rollers, thereby increasing the friction and making the rotating rollers more easily rotate; when the rotating rollers rotate, the comb teeth rotate, and until the comb teeth are in a vertical state and tightly contact the side plate, as shown in FIG. 7. Figure 8 At this time, the cleaning box continues to move downward, the comb teeth also tightly contact the side plate (at this time, the rotating rollers stop rotating), the comb teeth are stored, and the interference of the comb teeth on the cleaning work is avoided; when the cleaning box moves upward, the cleaning work is completed, the cleaning box drives the rotating rollers to rotate, and when the cleaning box does not contact the rotating rollers, the comb teeth are reset under the action of the torsion springs, are inserted into the bristles of the cleaning brush, and the cleaning box continues to move upward (after the cleaning box is separated from the rotating rollers, the cleaning box will continue to move upward), the bristles and the comb teeth move relative to each other, the comb teeth comb the bristles, on one hand, the comb teeth reduce the knotting of the bristles and improve the service life of the bristles, and on the other hand, the comb teeth comb the debris on the bristles, thereby ensuring the cleaning of the bristles and preparing for the next cleaning work.

[0018] Preferably, the side wall of the working cavity is inclined, and the vertical section of the fixed plate is in a herringbone shape.

[0019] During work, the side wall of the working cavity is inclined, and the vertical section of the fixed plate is in a herringbone shape, so that the side wall of the working cavity and the top of the fixed plate are both inclined, thereby reducing the residual debris and making the debris fall to the bottom of the working cavity for cleaning by the debris removal device.

[0020] The beneficial effects of the present application are as follows:

[0021] 1. A seamless steel pipe cutting table with a dust collection device, when cutting at one station is finished, the control cutting machine up, cleaning box down, so that the cleaning brush can contact the clamping unit, and the roller also down, so that its wheel surface contact to the top edge position of the bed; then the moving beam with the cutting machine and side plate along the bed, at this time the roller rotates, and then through the transmission with the cleaning brush rotating, the cleaning brush rotates and contacts the clamping unit (rotating cleaning brush enhances the cleaning effect), cleaning the way on the just cut seamless steel pipe, also cleaning the corresponding clamping unit, on the one hand to reduce the subsequent cleaning of the seamless steel pipe, on the other hand to clean the clamping unit debris, reduce the residue of the clamping unit debris, the cleaned debris falls to the bottom of the working cavity for the chip removal device to discharge.

[0022] 2. A seamless steel pipe cutting table with a dust collection device, when the torsion spring is in the original position, the comb teeth are in a horizontal state, and the comb teeth on the two rotating rollers can contact, when the cutting machine cuts the seamless steel pipe, the comb teeth pass through the bristles of the cleaning brush, fixing the bristles and reducing the interference of the cutting machine; when the cleaning box moves up, that is, the cleaning is finished, the cleaning box drives the rotating roller to rotate, when the cleaning box is not in contact with the rotating roller, the comb teeth reset under the action of the torsion spring, inserted into the bristles of the cleaning brush, the cleaning box continues to move up (after the cleaning box is set to be separated from the rotating roller, the cleaning box will continue to move up), the bristles and the comb teeth produce relative movement, the comb teeth comb the bristles, on the one hand to reduce the knot of the bristles and improve the service life of the bristles, on the other hand to comb the debris on the bristles, ensuring the cleanliness of the bristles and preparing for the next cleaning work.

For example, during the cutting process, debris will inevitably fall on the clamping unit 13. The debris on the clamping unit 13 also needs to 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. At this time, the debris on the clamping unit 13 is cleaned by using a high-pressure air gun, a high-pressure water gun or manually.
