Description

Technical Field

[0001] The present application relates to the technical field of laser cutting equipment, and in particular to an automobile pipe end ring cutting equipment. Background Art

[0002] There is an existing automobile pipe fitting, in which the outer wall of the middle section is ring-shaped with corrugations. Both sides of the pipe fitting need to be ring-cut by laser cutting equipment to keep the length of both sides of the corrugated section consistent. The laser cutting equipment irradiates the pipe fitting with a high-power density laser beam and cuts it. The pipe fitting material is heated to the vaporization temperature and evaporates to form holes. As the laser beam and the pipe fitting move relative to each other, the holes continuously form a slit of about 0.1 mm, thereby cutting off the pipe fitting.

[0003] In the related art, the laser cutting equipment generally includes a laser cutting head for emitting laser and a flywheel assembly for driving the laser cutting head for radial rotation cutting. The equipment also includes a set of clamping assemblies for clamping and fixing the pipe fittings. The clamping blocks in the clamping assemblies are driven by mechanisms such as cylinders, so that the pipe fittings can be clamped from the top and bottom.

[0004] In view of the above-mentioned related technologies, the clamping blocks are clamped and fixed from the upper and lower sides of the pipe fittings. After the laser cutting is completed, the pipe fittings need to be removed by other auxiliary mechanisms, which adds an additional cutting process. Therefore, it is necessary to provide a laser cutting device to simplify the cutting process of the pipe fittings, thereby improving the processing efficiency of the pipe fittings. Summary of the invention

[0005] In order to simplify the cutting process of pipe fittings and improve the processing efficiency of pipe fittings, the present application provides an automobile pipe end ring cutting device.

[0006] The present application provides an automobile pipe end ring cutting device adopts the following technical solution: An automobile pipe end ring cutting device comprises a feeding mechanism, a ring cutting mechanism, a clamping mechanism for fixing the pipe to the ring cutting mechanism, and a transport mechanism for transporting the pipe from the feeding mechanism to the clamping mechanism; The circular cutting mechanism includes two laser cutting heads for cutting the two ends of the pipe fittings, two sets of symmetrically arranged driving frames for driving the two laser cutting heads to move closer to or away from each other, a flywheel provided on the driving frames, and a lifting driving assembly provided on the flywheel for driving the laser cutting heads to move closer to or away from the end of the pipe fittings. The clamping mechanism is located between the two flywheels to horizontally clamp the pipe fittings to be cut. The clamping mechanism includes two symmetrically arranged strip-shaped clamping blocks that clamp along the length direction of the pipe and a clamping drive assembly that drives the two strip-shaped clamping blocks to move in the horizontal direction. The length direction of the strip-shaped clamping blocks is perpendicular to the diameter direction of the flywheel, and the two opposite side surfaces of the two strip-shaped clamping blocks are symmetrically provided with clamping grooves for abutting against the outer wall of the pipe.

[0007] By adopting the above technical solution, the strip clamping block in the clamping mechanism clamps along the length direction of the pipe, and its length direction is perpendicular to the diameter direction of the flywheel. The clamping block is pressed against the front and rear sides of the pipe to clamp the pipe. After the pipe is cut, the two clamping blocks move away from each other to automatically release the pipe. There is no need to add an additional unloading mechanism to assist unloading, which simplifies the unloading process, thereby reducing additional operating steps and required time, and significantly improving the processing efficiency of the pipe. The circular cutting mechanism accurately controls the flywheel and the lifting drive assembly, so that the laser cutting head accurately approaches or moves away from the end of the pipe, ensuring the accuracy and consistency of the cutting, and realizing the precise control of the length of both sides of the corrugated section, meeting the requirements of automotive pipes for cutting accuracy.

[0008] Furthermore, the two strip-shaped clamping blocks are vertically provided with a telescopic supporting plate for supporting the tube member on the opposite side walls, and the strip-shaped clamping blocks are provided with a first telescopic groove for the telescopic supporting plate to retract, and the first telescopic groove is provided with a first elastic member for the telescopic supporting plate to rebound.

[0009] By adopting the above technical solution, when the telescopic support plate is in the extended state, when the transfer mechanism transfers the pipe to between the two strip-shaped clamping blocks, the telescopic support plate can provide an additional support point for the pipe, and can enhance the stability of clamping when the pipe is long or heavy, and prevent the pipe from shifting or even falling due to unstable center of gravity during the transfer process. After the telescopic support plate stably supports the lower side of the pipe, the two strip-shaped clamping blocks approach each other and press against the front and rear sides of the pipe, and at this time the telescopic support plate retracts into the first telescopic groove through the squeezing of the strip-shaped clamping blocks.

[0010] Furthermore, the transfer mechanism includes an opening and closing clamping jaw assembly which is vertically arranged and used to clamp the pipe fittings dropped from the feeding mechanism, a mounting frame for mounting the opening and closing clamping jaw assembly, and a sliding guide rail which is arranged below the feeding mechanism and allows the mounting frame to slide between the transfer mechanism and the clamping mechanism; The opening and closing clamping jaw assembly comprises an opening and closing driving member fixedly connected to the upper side of the mounting frame and two finger clamping blocks symmetrically arranged and rotatably connected to the opening and closing driving member for clamping the pipe fitting.

[0011] By adopting the above technical solution, the finger clamps in the opening and closing jaw assembly are symmetrically arranged and rotatably connected to the opening and closing drive member. Driven by the opening and closing drive member, the finger clamps can accurately clamp the pipe fittings, and the opening and closing jaw assembly can vertically clamp the pipe fittings dropped from the feeding mechanism to maintain the stability and processing accuracy of the pipe fittings. The mounting frame slides horizontally between the transfer mechanism and the clamping mechanism through the sliding guide rail to achieve rapid transfer of the pipe fittings, improve transfer efficiency, and reduce the waiting time of the pipe fittings during processing. The finger clamps can be adjusted according to the size and shape of the pipe fittings to adapt to pipe fittings of different specifications, so that the transfer mechanism can handle various types of pipe fittings, improving the versatility and flexibility of the equipment.

[0012] Furthermore, the two opening and closing driving members are respectively provided with buffer receiving seats for receiving the two ends of the pipe fitting on the two side surfaces close to each other, and the buffer receiving seat includes an extension block fixedly connected to the opening and closing driving member and a receiving block installed on the extension block, and the receiving block is provided with an arc-shaped buffer groove on the top side, and the curvature of the arc-shaped buffer groove is greater than the curvature of the outer surface of the pipe fitting.

[0013] By adopting the above technical solution, when the pipe is clamped and transported by the opening and closing jaw assembly, when the pipe falls off the finger clamp due to the failure of the strip clamp or other mechanisms, the buffer receiving seat can provide an additional support interface to prevent the pipe from falling directly and being damaged by the impact of the ground or other hard objects. The arc-shaped buffer groove enables the receiving block to fit the outer surface of the pipe while providing a travel for the pipe to roll and buffer, reducing stress concentration and scratches.

[0014] Furthermore, the extension block is provided with a second telescopic groove for the receiving block to retract, and a second elastic member for driving the receiving block to rebound is provided in the second telescopic groove.

[0015] By adopting the above technical solution, the presence of the second elastic part enables the receiving block to produce a certain rebound when subjected to the pressure of the pipe, retract into the second telescopic groove and reduce the direct impact of the pipe on the receiving block through the rebound effect, thereby reducing the wear and damage of the receiving block, and helping to better protect the pipe from impact and damage during transportation.

[0016] Furthermore, the two flywheels are respectively provided with positioning components vertically on two opposite sides for positioning the two ends of the pipe, and the positioning components include a mounting tube fixedly connected to the center position of the flywheel and a positioning column telescopically connected to the mounting tube and used to extend into the interior of the pipe.

[0017] By adopting the above technical solution, the positioning column in the positioning assembly can extend into the interior of the pipe fitting to accurately position the two ends of the pipe fitting. On the one hand, it helps to ensure that the pipe fitting always maintains the correct position and posture during the cutting process, thereby improving the cutting accuracy and consistency. On the other hand, the positioning column can play a certain cushioning and protective role in the cutting of the pipe fitting, preventing the laser beam from penetrating the outer wall of the pipe fitting and reaching the opposite wall of the pipe, affecting the cutting accuracy.

[0018] Furthermore, the outer diameter of the positioning column gradually decreases from one end close to the mounting tube to one end far away from the mounting tube.

[0019] By adopting the above technical solution, the end diameter of the positioning column is smaller, making it tapered as a whole, so that it can be more easily inserted into the interior of pipes of different diameters. The outside of the tapered positioning column can always have an outer diameter that matches the inner diameter of the pipe, so that it fits tightly into the pipe port, providing more precise positioning, helping to reduce cutting errors caused by shaking or offset of the pipe, and improving cutting quality.

[0020] Furthermore, the end of the positioning column is integrally connected with a lead-out block for leading out slag in the pipe, and the outer diameter of the lead-out block gradually increases from the end connected to the positioning column to the end away from the positioning column, and the maximum outer diameter of the lead-out block is the same as the inner diameter of the pipe fitting.

[0021] By adopting the above technical solution, slag will be generated during the laser cutting process of the pipe fitting, and the lead-out block can extend into the interior of the pipe fitting and fit tightly against the inner wall of the pipe fitting. When the cutting is completed, the lead-out block and the positioning column will withdraw from both ends of the pipe fitting together, thereby effectively leading out the slag in the pipe fitting, keeping the interior of the pipe fitting clean, and avoiding the slag from affecting subsequent processing or use.

[0022] Furthermore, the feeding mechanism has a hopper for accommodating a plurality of pipe fittings and a feeding plate for pushing the pipe fittings to the transfer mechanism. The upper side of the feeding plate is provided with a limiting transverse groove for the pipe fittings to be inserted into at one end close to the transfer mechanism, and the hopper is provided with a discharge port at the bottom for the pipe fittings to fall into the limiting transverse groove.

[0023] By adopting the above technical solution, the hopper can accommodate several pipes, and the feeding plate can be used to push the pipes to the end of the feeding mechanism, so as to realize the automatic feeding of pipes, reduce manual intervention, and improve work efficiency and safety. The feeding port opened under the hopper can make the pipes fall smoothly into the limiting transverse groove, avoid the pipes from being blocked or stuck in the hopper, and ensure the continuity and stability of the feeding process. The limiting transverse groove opened on the feeding plate can ensure that the pipes maintain the correct position and posture during the pushing process, which helps to reduce the transportation problems caused by the displacement or tilt of the pipes, and improve the stability and reliability of the transportation mechanism.

[0024] Furthermore, a pushing assembly is provided in the hopper for pushing the pipes into the discharge port in sequence, and the pushing assembly includes a lifting plate movably connected to the hopper and vertically arranged with the pipes, and a driving connecting rod arranged on the inner wall of the hopper and driving the lifting plate to move.

[0025] By adopting the above technical solution, the lifting plate in the pushing assembly can continuously push the pipe from the bottom of the hopper to the discharge port under the drive of the driving connecting rod, thereby ensuring the stability and reliability of the feeding mechanism.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The circular cutting mechanism ensures that the laser cutting head is accurately close to or away from the end of the pipe through the precise control of the flywheel and the lifting drive assembly, and realizes the precise control of the length of both sides of the corrugated section, which meets the cutting accuracy requirements of automobile pipes. The strip clamping block of the clamping mechanism can simplify the material cutting process, reduce additional operation steps and required time, and significantly improve the processing efficiency of pipes; 2. The telescopic support plate can prevent the pipe fittings from shifting or even falling due to unstable center of gravity during the transfer process. The design of the buffer receiving seat and the arc-shaped buffer groove can prevent the pipe fittings from being damaged due to falling off during the transportation process. The rebound effect of the second elastic member can reduce the direct impact of the pipe fittings on the receiving block; 3. The positioning column in the positioning assembly can extend into the interior of the pipe fitting to accurately position both ends of the pipe fitting, ensuring that the pipe fitting always maintains the correct position and posture during the cutting process, improving the stability and accuracy of the cutting. The export block can extend into the interior of the pipe fitting and fit tightly to the inner wall of the pipe fitting to effectively export the slag in the pipe fitting.

[0037] The present application embodiment discloses a device for cutting the end of an automobile pipe. Figure 1 and Figure 2 The automobile pipe end ring cutting equipment comprises an operating table 1 and a feeding mechanism 2, a transfer mechanism 3, a clamping mechanism 4, and a ring cutting mechanism 5 arranged on the top side of the operating table 1. The feeding mechanism 2 can hold a number of pipes to be cut and transfer the pipes to the transfer mechanism 3 in sequence, the transfer mechanism 3 clamps the pipes and transfers the pipes to the clamping mechanism 4, the clamping mechanism 4 fixes the pipes, and the ring cutting mechanism 5 performs laser ring cutting on both ends of the pipe, so that the lengths of the two sides of the corrugated section of the pipe are equal.

[0038] Reference Figure 2 and Figure 3The feeding mechanism 2 includes a hopper 22, a pushing assembly 23 and a feeding plate 24. A support frame 21 is vertically arranged on the top side of the operating table 1. The hopper 22 is fixedly connected to the support frame 21 and a space is left between the hopper 22 and the top surface of the operating table 1 for installing components such as the feeding plate 24.

[0039] The spacing between the two side plates 221 of the hopper 22 is equal to / slightly greater than the length of the pipe to be cut, and two bottom plates 222 for supporting the pipe are vertically fixedly connected between the two opposite side surfaces of the two side plates 221 at the lower side. A discharge port 223 is reserved on the lower side of the hopper 22 near the transfer mechanism 3, and the discharge port 223 is large enough for a single pipe to fall. The bottom plate 222 is tilted downward from the side away from the discharge port 223 to the side where the discharge port 223 is located to guide the pipe to roll to the discharge port 223.

[0040] There are two pusher assemblies 23, and the two sets of pusher assemblies 23 are respectively arranged under the two bottom plates 222 of the hopper 22. The pusher assemblies 23 include a lifting plate 231 for lifting the pipe fittings and a driving connecting rod 232 for driving the lifting plate 231 to move. The two bottom plates 222 are respectively provided with lifting grooves 2221 for corresponding installation of the two lifting plates 231 along the length direction, and one end of the lifting plate 231 close to the discharge port 223 is hinged to the bottom plate 222. The driving connecting rod 232 is installed under the bottom plate 222 and is located on the side away from the discharge port 223. The execution end of the driving connecting rod 232 is hinged to the bottom side of the lifting plate 231. The lifting plate 231 is perpendicular to the length direction of the pipe fittings and lifts the pipe fittings at the bottom side of the pipe fittings, which plays an auxiliary role in the rolling of the pipe fittings toward the side of the discharge port 223.

[0041] The feeding plate 24 is horizontally installed below the hopper 22 and driven by a cylinder or other components, so as to reciprocate between the hopper 22 and the transfer mechanism 3. A limiting transverse groove 241 for accommodating a single pipe is provided on the upper side of the feeding plate 24 at one end close to the transfer mechanism 3, and a clearance opening 242 for making way for the corrugated section of the pipe is provided at the middle position of the feeding plate 24.

[0042] The support frame 21 is also provided with a correction assembly 25 for correcting the position of the pipe fittings on one side close to the discharge port 223 of the hopper 22. The correction assembly 25 includes a toggle plate 251, a toggle cylinder 252 and a limit plate 253 arranged relatively on both sides of the support frame 21. The toggle plate 251 is fixedly connected to the end of the piston rod of the toggle cylinder 252 and driven by the toggle cylinder 252. The limit plate 253 is fixedly connected to the top side of the operating table 1. When the feeding plate 24 pushes the pipe fittings to be cut out of the hopper 22, the lower edge of the toggle plate 251 pushes the pipe fittings against the side of the corrugated section of the pipe fittings until the end of the pipe fittings abuts against the side of the limit plate 253, thereby correcting the position of the pipe fittings to be cut, so that the pipe fittings can smoothly enter the transfer mechanism 3.

[0043] The driving connecting rod 232 is driven by the motor and drives the side of the lifting plate 231 away from the discharge port 223 to perform a lifting action in the hopper 22. The upper side of the lifting plate 231 is lifted to form an inclined surface so that the pipe can roll along the inclined surface to the discharge port 223. When the feeding plate 24 is located below the hopper 22 under the action of the cylinder, the limiting transverse groove 241 can be aligned with the bottom of the discharge port 223, and the pipe dropped from the discharge port 223 enters the limiting transverse groove 241, and is then pushed to the side of the transfer mechanism 3 by the feeding plate 24.

[0044] Reference Figure 3 and Figure 4 The transport mechanism 3 includes an opening and closing clamping jaw assembly 31, a mounting frame 32 and a sliding guide rail 33. The opening and closing clamping jaw assembly 31 is used to clamp the pipes transported by the feeding plate 24. The mounting frame 32 is used to install the opening and closing clamping jaw assembly 31. The sliding guide rail 33 allows the mounting frame 32 to slide between the transport mechanism 3 and the clamping mechanism 4. The sliding guide rail 33 is fixedly connected to the upper side of the operating platform 1 and is located below the hopper 22. The mounting frame 32 is slidably mounted on the sliding guide rail 33. The sliding guide rail 33 drives the mounting frame 32 through the motor screw. There are two opening and closing clamping jaw assemblies 31. Both sets of opening and closing clamping jaw assemblies 31 are installed above the mounting frame 32 and are symmetrically placed on both sides.

[0045] The opening and closing clamping jaw assembly 31 includes an opening and closing driving member 311 fixedly connected to the upper side of the mounting frame 32 and two finger clamping blocks 312 symmetrically arranged and rotatably connected to the opening and closing driving member 311. The finger clamping blocks 312 are opened and closed by the opening and closing driving member 311, thereby clamping or releasing the pipe. In this embodiment, the maximum opening angle of the two finger clamping blocks 312 can reach 180°, thereby preventing the finger clamping blocks 312 from interfering with the clamping mechanism 4.

[0046] In order to improve the stability of the pipe connection between the opening and closing clamping jaw assembly 31 and the clamping mechanism 4 and prevent the pipe from falling during transfer, the opening and closing driving member 311 of this embodiment is further provided with a buffer receiving seat 34 on the side wall for supporting both ends of the pipe. Figure 5 The buffer receiving seat 34 includes an extension block 341 and a receiving block 342. The extension block 341 is fixedly connected to the side wall of the opening and closing driving member 311, and the receiving block 342 is installed on the upper side of the extension block 341. The extension block 341 is provided with a second telescopic groove 3411 on the upper side for the receiving block 342 to retract into, and a second elastic member 3412 is provided in the second telescopic groove 3411 for the receiving block 342 to rebound. The top side of the receiving block 342 is provided with an arc-shaped buffer groove 3421, and the curvature of the arc-shaped buffer groove 3421 is greater than the curvature of the outer surface of the pipe fitting.

[0047] The buffer receiving seat 34 provides an additional support interface to prevent the pipe from falling directly and being damaged by the impact of the ground or other hard objects. The arc-shaped buffer groove 3421 enables the receiving block 342 to fit the outer surface of the pipe while providing a travel for the pipe to roll and buffer, thereby reducing stress concentration and scratches. The second elastic member 3412 enables the receiving block 342 to rebound to a certain extent when subjected to the pressure of the pipe, retracting into the second telescopic groove 3411 and reducing the direct impact of the pipe on the receiving block 342 through the rebound effect.

[0048] Reference Figure 6 and Figure 7 The clamping mechanism 4 includes two symmetrically arranged strip-shaped clamping blocks 41 and a clamping driving assembly 42 for driving the two strip-shaped clamping blocks 41 to move in the horizontal direction. The strip-shaped clamping blocks 41 clamp the pipe along its length direction and press against the front and rear sides of the pipe. Clamping grooves 411 for matching with the outer wall of the pipe are symmetrically opened on the opposite sides of the two strip-shaped clamping blocks 41. The clamping driving assembly 42 drives the two strip-shaped clamping blocks 41 to move closer to or away from each other through a cylinder, thereby clamping the pipe to be cut transported by the opening and closing jaw assembly 31. After the ring cutting mechanism 5 completes the cutting of the pipe, the two strip-shaped clamping blocks 41 move away from each other to release the pipe.

[0049] In order to improve the stability of the clamping mechanism 4 and the opening and closing clamping jaw assembly 31 when the pipe is connected, and to prevent the pipe from falling, two strip-shaped clamping blocks 41 are vertically provided with telescopic supporting plates 43 for supporting the pipe on opposite side walls. The number of telescopic supporting plates 43 on each strip-shaped clamping block 41 is two and they are symmetrically arranged on both sides of the strip-shaped clamping block 41. The strip-shaped clamping block 41 is provided with a first telescopic groove 412 for the telescopic supporting plate 43 to retract, and a first elastic member 413 is provided in the first telescopic groove 412 for the telescopic supporting plate 43 to rebound.

[0050] When the two-shaped clamp blocks 41 are in a state of being away from each other, the telescopic support plate 43 extends out. When the transfer mechanism 3 transfers the pipe fittings between the two-shaped clamp blocks 41, the telescopic support plate 43 can provide an additional support point for the pipe fittings to prevent the pipe fittings from falling due to unstable center of gravity during the transfer process. After the telescopic support plate 43 stably supports the lower side of the pipe fittings, the two-shaped clamp blocks 41 approach each other and are clamped on the front and rear sides of the pipe fittings through the clamping grooves 411. At this time, the telescopic support plate 43 is squeezed by the strip-shaped clamp blocks 41 and retracts into the first telescopic groove 412.

[0051] Reference Figure 6 and Figure 8The circular cutting mechanism 5 includes two laser cutting heads 51 for cutting the two ends of the pipe, two sets of driving frames 52 symmetrically arranged on both sides of the operating table 1 and used to drive the two laser cutting heads 51 to move closer or farther from each other, flywheels 53 respectively arranged on the two driving frames 52 and driving the laser cutting heads 51 to rotate, and a lifting driving assembly 54 arranged on the flywheel 53 and driving the laser cutting heads 51 to move up and down. The clamping mechanism 4 is located between the two flywheels 53 to horizontally clamp the pipe to be cut, and the diameter direction of the flywheel 53 is perpendicular to the length direction of the strip clamping block 41.

[0052] After the clamping mechanism 4 clamps the pipe to be cut, the driving frame 52 is driven by the motor screw to drive the two flywheels 53 close to the end of the pipe, and the lifting drive assembly 54 drives the laser cutting head 51 to descend to the position to be cut of the pipe through the cylinder. The flywheel 53 is then driven by the motor of the driving frame 52, thereby driving the laser cutting head 51 to rotate and cut around the outer wall of the pipe.

[0053] The two flywheels 53 are symmetrically provided with positioning components 55 for positioning the two ends of the pipe fittings on the two opposite sides, respectively. The positioning components 55 include a mounting tube 551 vertically fixedly connected to the center of the flywheel 53, a positioning column 552 telescopically connected to the mounting tube 551 and used to extend into the interior of the pipe fitting, and a lead-out block 553 integrally connected to the end of the positioning column 552 and used to lead out the slag in the pipe. The outer diameter of the positioning column 552 gradually decreases from the end close to the mounting tube 551 to the end away from the mounting tube 551. The outer diameter of the lead-out block 553 gradually increases from the end connected to the positioning column 552 to the end away from the positioning column 552, and the maximum outer diameter of the lead-out block 553 is the same as the inner diameter of the pipe fitting.

[0054] The end of the positioning column 552 has a smaller diameter and is tapered as a whole, so that it can be inserted into pipes of different diameters. The outer diameter of the tapered positioning column 552 can always match the inner diameter of the pipe, so that it fits tightly to the pipe port and reduces the cutting error caused by the shaking or deviation of the pipe. Slag will be generated during the laser cutting of the pipe. The guide block 553 extends into the pipe and fits tightly to the inner wall of the pipe. When the cutting is completed, the guide block 553 and the positioning column 552 are driven by the mounting tube 551 to withdraw from both ends of the pipe, and the slag in the pipe is guided out to keep the inside of the pipe clean.

[0055] Reference Figure 1 and Fig. 9 A receiving frame 11 for receiving finished pipe fittings is provided below the strip clamp block 41 on the operating table 1. Two waste frames 12 for receiving waste pipe fittings are placed on the ground on both sides of the operating table 1. Two guiding slopes 13 for guiding waste to slide into the waste frames 12 are symmetrically provided on both sides of the operating table 1.

[0056] The implementation principle of the automobile pipe end ring cutting device in the embodiment of the present application is as follows: the feeding mechanism 2 holds a number of pipes to be cut through the hopper 22, and the pipes roll to the discharge port 223 under the guidance of the bottom plate 222. The lifting plate 231 of the pushing assembly 23 lifts the pipe under the action of the driving connecting rod 232, and assists the pipe to roll to the discharge port 223. The feeding plate 24 reciprocates under the drive of the cylinder, receives the falling pipe through the limiting transverse groove 241, and makes way for the corrugated section of the pipe through the making way opening 242. The toggle plate 251 of the correction assembly 25 is driven by the toggle cylinder 252 to correct the position of the pipe so that it can smoothly enter the transfer mechanism 3.

[0057] The opening and closing clamping jaw assembly 31 of the transfer mechanism 3 drives the finger clamp block 312 to open and close through the opening and closing driving member 311, clamping the two ends of the pipe fittings on the feeding plate 24, and the mounting frame 32 is driven by the motor screw to slide on the sliding guide rail 33 to transfer the pipe fittings to the position of the clamping mechanism 4. The buffer receiving seat 34 of the opening and closing driving member 311 provides additional support to prevent the pipe fittings from falling during the handover process.

[0058] The strip clamps 41 of the clamping mechanism 4 are driven by the clamping drive assembly 42 to move closer to each other, clamp the pipe through the clamping groove 411, and the telescopic support plate 43 provides additional support on the lower side of the pipe to prevent the pipe from falling. The lifting drive assembly 54 of the ring cutting mechanism 5 controls the lifting and lowering of the laser cutting head 51, and the laser cutting head 51 rotates around the outer wall of the pipe to cut under the drive frame 52 and the flywheel 53. The positioning column 552 and the guide block 553 of the positioning assembly 55 extend into the interior of the pipe to ensure cutting accuracy and guide out slag.
