Description

Technical Field

[0001] This utility model belongs to the technical field of pipe material conveying devices, and in particular relates to a material conveying device for a pipe laser cutting machine. Background Technology

[0002] The raw material conveying device for tube laser cutting machines is a core auxiliary mechanism adapted to tube laser cutting machines, used to achieve automated or semi-automated feeding and precise delivery of tube raw materials. Its core function is to smoothly and orderly convey tube raw materials of different specifications, such as round tubes, square tubes, and rectangular tubes, from the storage area to the laser cutting station. During the cutting process, according to processing requirements, the device achieves precise feeding, positioning, and posture correction of the tubes through the coordinated action of components such as servo motors, transmission roller groups, and positioning fixtures. It also has the ability to adapt and adjust parameters such as tube diameter and length, effectively replacing the tedious operation of manual feeding, reducing collision damage during tube transportation, ensuring the relative positional accuracy of the tubes and the laser cutting head, and thus improving the processing efficiency, cut quality, and continuous automated production of tube laser cutting machines.

[0003] However, in the process of using existing pipe cutting devices, the temporary fixing devices are complicated and it is difficult to achieve stable and efficient material positioning when conveying raw materials. This not only affects the conveying efficiency, but also leads to a decrease in subsequent cutting accuracy due to unstable fixing. Utility Model Content

[0004] The purpose of this utility model is to provide a raw material conveying device for a tube laser cutting machine. By setting a fixing part, it solves the problem that when conveying raw materials, the temporary fixing device is complicated and it is difficult to achieve stable and efficient raw material positioning, which not only affects the conveying efficiency, but also leads to a decrease in subsequent cutting accuracy due to unstable fixing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a raw material conveying device for a tube laser cutting machine, comprising an L-shaped mounting plate, and further comprising: a fixing part disposed on the L-shaped mounting plate; a conveying part disposed at the bottom of the L-shaped mounting plate; the fixing part comprising a fixing assembly mounted on the L-shaped mounting plate; and a cutting assembly mounted on the L-shaped mounting plate; the fixing assembly comprising a support plate fixedly connected to the top of the L-shaped mounting plate, an H-shaped plate fixedly connected to the left side of the support plate, a slide rail fixedly connected to the bottom of the H-shaped plate, and two fixing plates slidably connected to the outer surface of the slide rail. Two fixed plates are provided with pipe materials on one side close to each other. A sliding groove is provided on the support plate. A sliding plate is slidably connected in the sliding groove. Two connecting plates are hinged on the sliding plate. The ends of the two connecting plates away from the sliding plate are hinged to the two fixed plates. A driving component is provided on the support plate. The bottom ends of the two fixed plates extend to the outside of the L-shaped mounting plate and are slidably connected to the L-shaped mounting plate. The driving component includes a hydraulic push rod fixedly connected to the top of the support plate. The output end of the hydraulic push rod is fixedly connected to the sliding plate and extends to the outside of the support plate and is slidably connected to the support plate.

[0006] Furthermore, the conveying unit includes a conveying assembly disposed at the bottom of the L-shaped mounting plate; and a driving assembly mounted on the conveying assembly.

[0007] Furthermore, the cutting assembly includes a sliding frame fixedly connected to the top of the L-shaped mounting plate. A second sliding plate is slidably connected inside the sliding frame. A laser head is fixedly connected to the front of the second sliding plate. A second hydraulic push rod is fixedly connected to the top of the sliding frame. The output end of the second hydraulic push rod is fixedly connected to the second sliding plate. The output end of the second hydraulic push rod extends into the sliding frame and is slidably connected to the sliding frame. The sliding frame at the top of the L-shaped mounting plate provides a stable sliding track for the second sliding plate, ensuring that the second sliding plate moves the laser head along a fixed path and avoiding deviation that affects the cutting accuracy.

[0008] Furthermore, the conveying assembly includes a body mounted on an L-shaped mounting plate. A cutting pneumatic rotary chuck is located on the right side of the body. The right side of the tube material extends into the cutting pneumatic rotary chuck. A second slide groove is provided on the body. A screw is rotatably connected to the second slide groove. A sliding plate three is threadedly connected to the outer wall of the screw. The top of the sliding plate three extends out of the second slide groove and is fixedly connected to the L-shaped mounting plate. A balancing component is provided in the second slide groove. The left end of the screw extends out of the body and is rotatably connected to the body. The balancing component includes a balancing rod assembly fixedly connected in the second slide groove. The balancing rod assembly passes through the sliding plate three and is slidably connected to the sliding plate three. The balancing rod assembly consists of two sliding rods. The body on the L-shaped mounting plate provides basic support for the conveying and fixing of the tube material. The cutting pneumatic rotary chuck on the right side of the body can firmly clamp the right end of the tube material, preventing the tube material from shifting or shaking during conveying or cutting, and ensuring the accuracy of subsequent cutting operations.

[0009] Furthermore, the drive assembly includes a motor sleeve fixedly connected to the left side of the machine body, on which a motor is fixedly connected. The output shaft of the motor is fixedly connected to a screw via a coupling. The motor sleeve on the left side of the machine body provides a stable mounting position for the motor, preventing the motor from shifting or loosening due to vibration during operation, providing a stable foundation for power output, and ensuring the reliability of the subsequent transmission process.

[0010] This utility model has the following beneficial effects: 1. By setting a fixing part, when the tube material needs to be fed and cut, one end can be passed through the cutting pneumatic rotary chuck on the machine body, and then the motor is started. The motor, through the screw and the balance bar group, makes the sliding plate three drive the fixing component on the L-shaped mounting plate to move to the end of the tube material. After the fixing component is in place, the hydraulic push rod one is started, which drives the sliding plate one to move upward. Because the other end of the two connecting plates of the sliding plate one is hinged to the two fixing plates on the slide rail, when the sliding plate one moves upward, the two fixing plates move closer to each other along the slide rail through the transmission of the connecting plates, clamping and fixing the tube material. This setting can realize the rapid and stable clamping of the tube material and ensure the positional accuracy of subsequent conveying. 2. By setting up a conveyor section, after the fixing component secures the tube material, the motor is restarted. The screw and balance bar assembly cause the slide plate three to move the tube material held by the fixing component backward. After it reaches the position, the fixing component releases the tube material, and the motor then drives the slide plate three and related components to reset. After the reset is completed, the hydraulic push rod two is activated, which drives the slide plate two and the laser head to move down along the slide frame to perform laser cutting on the tube material. During cutting, the pneumatic rotary chuck can be activated simultaneously to clamp and rotate the tube material to complete the circumferential cutting. This setup can realize automated and precise cutting of tube materials, improving processing efficiency and cutting quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, this utility model is a raw material conveying device for a tube laser cutting machine, including an L-shaped mounting plate 1, and further including: a fixing part 2, which is disposed on the L-shaped mounting plate 1; and a conveying part 3, which is disposed at the bottom of the L-shaped mounting plate 1.

[0017] The fixing part 2 includes a fixing component 21, which is mounted on the L-shaped mounting plate 1; and a cutting component 22, which is also mounted on the L-shaped mounting plate 1. The fixing component 21 includes a support plate 211 fixedly connected to the top of the L-shaped mounting plate 1. An H-shaped plate 212 is fixedly connected to the left side of the support plate 211. A slide rail 213 is fixedly connected to the bottom of the H-shaped plate 212. Two fixing plates 214 are slidably connected to the outer surface of the slide rail 213. A tube material 215 is provided on one side of the two fixing plates 214 that are close to each other. A slide groove 216 is provided on the support plate 211. A slide plate 217 is slidably connected in the slide groove 216. Two connecting plates 217 are hinged to the slide plate 217. 18. The ends of the two connecting plates 218 furthest from the slide plate 217 are hinged to the two fixed plates 214. A driving component is provided on the support plate 211. The bottom ends of the two fixed plates 214 extend outside the L-shaped mounting plate 1 and are slidably connected to the L-shaped mounting plate 1. The cutting assembly 22 includes a slide frame 221 fixedly connected to the top of the L-shaped mounting plate 1. A slide plate 222 is slidably connected inside the slide frame 221. A laser head 223 is fixedly connected to the front of the slide plate 222. A hydraulic push rod 224 is fixedly connected to the top of the slide frame 221. The output end of the hydraulic push rod 224 is fixedly connected to the slide plate 222. The output end of the hydraulic push rod 224 extends into the slide frame 221 and is connected to the slide plate 222. 1. Sliding connection. The driving component includes a hydraulic push rod 219 fixedly connected to the top of the support plate 211. The output end of the hydraulic push rod 219 is fixedly connected to the slide plate 217. The output end of the hydraulic push rod 219 extends to the outside of the support plate 211 and is slidably connected to the support plate 211. By setting the fixing part 2, if it is necessary to feed and cut the tube material 215 during use, one end of the tube material 215 can be passed through the cutting pneumatic rotary chuck 312 on the machine body 311. After passing through, the motor 322 is started. The motor 322 will drive the fixed component 21 on the L-shaped mounting plate 1 to move the slide plate 315 to the point where the tube material 215 passes through the screw 314 and cooperate with the balance bar group 316. Once the fixing component 21 is in place, the hydraulic push rod 219 is activated. The hydraulic push rod 219 will drive the slide plate 217 to move upward. Since there are two connecting plates 218 hinged on the slide plate 217, and the other ends of the two connecting plates 218 are hinged to two fixing plates 214 sliding on the slide rail 213, during the process of the hydraulic push rod 219 driving the slide plate 217 to move upward, the two fixing plates 214 hinged to them can slide closer to each other along the slide rail 213 through the transmission of the two connecting plates 218, thereby clamping and fixing the tube material 215. Through this setting, the tube material can be quickly and stably clamped, ensuring the positional accuracy in the subsequent conveying process.

[0018] The conveying unit 3 includes a conveying assembly 31, which is disposed at the bottom of the L-shaped mounting plate 1; and a drive assembly 32, which is mounted on the conveying assembly 31. The conveying assembly 31 includes a body 311 disposed on the L-shaped mounting plate 1. A cutting pneumatic rotary chuck 312 is disposed on the right side of the body 311, and the right side of the tube material 215 extends into the cutting pneumatic rotary chuck 312. A second slide groove 313 is provided on the body 311, and a screw 314 is rotatably connected in the second slide groove 313. A sliding plate 315 is threadedly connected to the outer wall of the screw 314. The top of 15 extends to the outside of the slide groove 313 and is fixedly connected to the L-shaped mounting plate 1. A balancing component is provided inside the slide groove 313. The left end of the screw 314 extends to the outside of the body 311 and is rotatably connected to the body 311. The drive assembly 32 includes a motor sleeve 321 fixedly connected to the left side of the body 311. A motor 322 is fixedly connected to the motor sleeve 321. The output shaft of the motor 322 is fixedly connected to the screw 314 through a coupling. The balancing component includes a balance bar assembly 316 fixedly connected inside the slide groove 313. The balance bar assembly 316 passes through the slide plate 315 and is connected to the slide plate. The sliding connection 315 and the balance bar assembly 316 consist of two sliding bars. Through the conveying unit 3, after the fixing component 21 secures the tube material 215, the motor 322 is restarted. The motor 322, via the screw 314 and in conjunction with the balance bar assembly 316, causes the sliding plate 315 to move the tube material 215 held by the fixing component 21 on the L-shaped mounting plate 1 backward. After it reaches its position, the fixing component 21 is activated to release the tube material 215. Then, the motor 322 is restarted, and via the screw 314, the sliding plate 315 and the fixing component 216 on the L-shaped mounting plate 1 are moved backward. 1. The cutting assembly 22 is reset. After the reset is completed, the hydraulic push rod 224 is activated. The hydraulic push rod 224 will drive the slide plate 222 and the laser head 223 on it to slide down along the slide frame 221, so that the laser head 223 can perform laser cutting on the tube material 215. During the cutting process of the laser head 223, the cutting pneumatic rotary chuck 312 can be activated simultaneously to clamp the tube material 215 and drive it to rotate, so that the laser head 223 can complete the circumferential cutting. Through this setting, the automated and precise cutting of the tube material can be realized, improving the processing efficiency and cutting quality.

[0019] The 312 pneumatic rotary chuck for cutting equipment is a clamp that typically houses a pneumatic rotary cylinder, eliminating the need for an additional rotary cylinder. It features a forced release clamping function, making it suitable for automated production. Easy to install, the enlarged pneumatic chuck cylinder enhances clamping force, and the collet's secondary jaws are quickly replaceable, offering high operational flexibility. Some chucks feature a central through-hole design, allowing for continuous loading and unloading without stopping the machine, thus increasing production capacity. A recommended model is the Baorui JA7-40, which has a 44mm through-hole clamping capacity.

[0020] It should be noted that the control of motor 322, hydraulic push rod 219, hydraulic push rod 224, and cutting pneumatic rotary chuck 312 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC. The laser head 223 emits a high-power-density laser beam, which is focused and irradiates the surface of the workpiece, causing the material to melt or vaporize instantly. At the same time, high-pressure gas blows away the slag, forming a cutting kerf. The CNC system control adopts CNC technology and controls the cutting path, speed, and power through a computer program to achieve high-precision automated cutting.

[0021] A specific application of this embodiment is as follows: When using the material, if it is necessary to feed and cut the tube material 215, one end of the tube material 215 can be passed through the cutting pneumatic rotary chuck 312 on the machine body 311. After passing through, the motor 322 is started. The motor 322, through the screw 314 and in conjunction with the balance bar assembly 316, causes the sliding plate 315 to move the fixing component 21 on the L-shaped mounting plate 1 to the through end of the tube material 215. When the fixing component 21 is in place, the hydraulic push rod 219 is activated, which will drive the sliding plate 219. As slide plate 217 moves upward, two connecting plates 218 are hinged to it, and the other ends of both connecting plates 218 are hinged to two fixed plates 214 sliding on slide rail 213. Therefore, during the upward movement of slide plate 217 driven by hydraulic push rod 219, the two fixed plates 214 hinged to them can slide closer to each other along slide rail 213 through the transmission of the two connecting plates 218, thereby clamping and fixing the tube material 215. This setting enables rapid and stable clamping of the tube material, ensuring subsequent conveying. Positional accuracy during the process; after the fixing component 21 has fixed the tube material 215, the motor 322 is started again. The motor 322, through the screw 314 and in conjunction with the balance bar assembly 316, causes the sliding plate 315 to move the tube material 215 held by the fixing component 21 on the L-shaped mounting plate 1 backward. After it moves into place, the fixing component 21 is started to release the tube material 215. Then the motor 322 is started again, and through the screw 314, the sliding plate 315, the fixing component 21 on the L-shaped mounting plate 1, and the cutting component 22 are reset. Once the position is completed, the hydraulic push rod 224 is activated. The hydraulic push rod 224 will drive the slide plate 222 and the laser head 223 on it to slide downward along the slide frame 221, so that the laser head 223 can perform laser cutting on the tube material 215. During the cutting process of the laser head 223, the cutting pneumatic rotary chuck 312 can be activated simultaneously to clamp the tube material 215 and drive it to rotate, so that the laser head 223 can complete the circumferential cutting. Through this setting, the automated and precise cutting of the tube material can be achieved, improving processing efficiency and cutting quality.
