Description

Technical Field

[0001] The present application relates to the technical field of pipe processing equipment, and in particular to a novel side-mounted two-chuck pipe cutting machine. Background Art

[0002] In the field of mechanical processing, especially in the cutting of pipes, efficient pipe cutting machines play an important role in improving production efficiency and product quality. With the continuous development of industrial production, the requirements for pipe cutting machines are getting higher and higher. They must not only be able to adapt to pipes of different diameters and lengths, but also have efficient loading, unloading and automatic control functions to reduce manual intervention and improve production efficiency and safety. In this context, it is particularly necessary to develop a device that can achieve efficient and automated pipe cutting.

[0003] In order to achieve the above goals, there are many solutions commonly used in the prior art. First, some equipment realizes automatic loading and unloading of pipes by configuring fixed loading and unloading devices on the cutting machine. Although such devices can reduce the labor intensity of manual labor to a certain extent, their fixed design is difficult to adapt to the processing needs of pipes of different sizes. Another common method is to install an adjustable chuck on the cutting machine to adapt to pipes of different sizes, and load and unload manually or semi-automatically. Although this solution has improved adaptability, its degree of automation is still low, and it is impossible to achieve efficient and continuous production.

[0004] However, the fixed loading and unloading devices and the adjustable chuck solutions in the prior art have certain defects. In particular, when cutting pipes of different diameters, the unloading device in the prior art solution cannot effectively adapt to the change in the distance between the pipe and the unloading device after the pipe is rotated, resulting in unstable support of the pipe during the cutting process, affecting the cutting accuracy; in addition, during the unloading process, since the distance between the unloading device and the cutting device is fixed, the unloading device is prone to collide with the cutting device when it flips and drives the cut pipe to unload, which not only affects the safety and service life of the equipment, but also reduces production efficiency. Therefore, a new technical solution is urgently needed to solve the above problems. Summary of the invention

[0005] In order to improve the safety, cutting accuracy and production efficiency of the equipment, the present application provides a new side-mounted two-chuck pipe cutting machine.

[0006] The present application provides a new side-mounted two-chuck pipe cutting machine, which adopts the following technical solution: A novel side-mounted two-chuck pipe cutting machine comprises a bed, a front chuck, a rear chuck, a cutting device, a loading device and a unloading device. The front chuck, the rear chuck, the cutting device, the loading device and the unloading device are all located on the same side of the bed, the rear chuck is slidably connected to the bed along the conveying direction of the pipe, the cutting device is fixedly connected to the bed, the loading device and the unloading device are arranged on both sides of the cutting device along the conveying direction of the pipe, the front chuck is located on the side of the unloading device close to the loading device, and the rear chuck is located on the side of the front chuck away from the unloading device, the unloading device comprises an unloading main The frame comprises a material unloading lifting frame, a support plate, a flip cylinder, and several first rollers. The main material unloading frame is slidably connected to the bed along the conveying direction of the pipe, the material unloading lifting frame is slidably connected to the main material unloading frame in the vertical direction, the flip cylinder body is rotatably connected to the material unloading lifting frame, the end of the support plate away from the bed is rotatably connected to the telescopic shaft end of the flip cylinder, the end of the support plate close to the bed is rotatably connected to the material unloading lifting frame, several first rollers are evenly arranged along the conveying direction of the pipe, the first rollers are rotatably connected to the support plate in a direction perpendicular to the conveying direction of the pipe, and one circumferential side of the first roller is located outside the support plate.

[0007] By adopting the above technical scheme, the operator places the pipe to be processed on the end of the loading device away from the bed, and the loading device transports the pipe between the front chuck and the rear chuck. The rear chuck clamps the pipe and pushes the pipe to move toward the front chuck. Then one end of the pipe passes through the front chuck and slides on the first roller. The unloading device supports the pipe; the front chuck clamps the pipe, and the cutting device cuts the pipe. While cutting, the front chuck drives the pipe to rotate. When the square pipe rotates, the distance between the outer wall of the square pipe and the first roller changes. The unloading lifting frame drives the support plate and the first roller to slide on the unloading main frame in the vertical direction, which can adapt to this distance change. The support plate and the first roller slide up and down with the rotation of the pipe and can also adapt to pipes of different diameters, thereby improving the cutting accuracy. After the cutting device completes cutting, the unloading device moves to a position away from the rear chuck, so that the unloading device and the cut pipe on the unloading device are out of the range of the cutting device, so that when the pallet is turned over for unloading, it is avoided that the cutting device is collided during unloading, thereby causing damage to the equipment, and at the same time, it is convenient to place a box for storing the cut pipe on the side of the unloading device away from the bed. After the pipe cutting is completed, the turning cylinder can drive the pallet and the first roller to turn over, and the pipe carried on the first roller can be unloaded, thereby improving the unloading efficiency.

[0008] Optionally, the front chuck is slidably connected to the bed along the conveying direction of the pipe, and the unloading main frame is fixedly connected to the front chuck.

[0009] By adopting the above technical scheme, the front chuck is slidably connected to the bed along the conveying direction of the pipe, and the unloading main frame is fixedly connected to the front chuck, so that the front chuck can slide synchronously according to the pipe conveying position, thereby ensuring the stability and accuracy of the pipe during the cutting process. At the same time, the fixed connection between the unloading main frame and the front chuck ensures the relative position relationship between the unloading device and the front chuck, further improving the cutting accuracy and stability.

[0010] Optionally, a sliding cylinder is fixedly provided on the bed, the telescopic shaft end of the sliding cylinder is fixedly connected to the front chuck, and the axis direction of the sliding cylinder is the same as the conveying direction of the pipe.

[0011] By adopting the above technical solution, the sliding cylinder fixed on the bed can drive the front chuck to move along the conveying direction of the pipe, achieving precise positioning and stable support, thereby improving the accuracy and stability of the pipe cutting process. The axis direction of the sliding cylinder is the same as the conveying direction of the pipe, ensuring that the front chuck can accurately follow the movement of the pipe, further improving the cutting accuracy.

[0012] Optionally, the feeding device includes several feeders and several feeding follower mechanisms. The direction in which the feeders transport the pipes is perpendicular to the direction in which the pipes are conveyed and cut. The feeding follower mechanisms are located on the side of the feeders away from the unloading device and close to the bed. The several feeders and several feeding follower mechanisms are arranged one by one along the direction in which the pipes are conveyed and cut.

[0013] By adopting the above technical scheme, several feeders synchronously transport the pipe from the end away from the bed to the top of the feeding follower mechanism, thereby realizing stable transportation of the pipe. Several feeding follower mechanisms simultaneously perform centering operations on the pipe, thereby realizing automatic centering of the pipe and improving feeding efficiency and cutting accuracy.

[0014] Optionally, the loading machine includes a loading rack, a chain and a pushing block, the pushing blocks are evenly arranged on the chain along the chain transmission direction, the lower end of the chain is located in the loading rack, the upper end of the chain is located above the loading rack, and two buffer blocks are provided on the upper end surface of the loading rack and at one end away from the bed, the two buffer blocks are arranged along the direction of pipe conveying and cutting, and an inclined surface is provided on the upper end of the buffer block on the side close to the bed, the height of the inclined surface gradually decreases in the direction close to the bed, the upper end surface of the buffer block is lower than the upper end surface of the pushing block in vertical height, and the lowest point of the inclined surface The first guard plate and the second guard plate are arranged on one side of the bed close to the loader along the direction of pipe conveying and cutting at a vertical height not higher than the highest point of the chain, and several loaders are located between the first guard plate and the second guard plate. The first guard plate is detachably connected to the bed, and the second guard plate is fixedly connected to the bed. The upper end surfaces of the first guard plate and the second guard plate at one end away from the bed are higher than the upper end surface of the pushing block at a vertical height, and the upper end surfaces of the first guard plate and the second guard plate at one end close to the bed are not higher than the highest point of the chain at a vertical height.

[0015] By adopting the above technical solution, the position of the first guard plate is adjusted so that the distance between the first guard plate and the second guard plate is adapted to the length of the pipe. The pipe is first placed on the buffer block, and the chain drives the push block to move toward the bed. The push block drives the pipe to break away from the buffer block and fall onto the chain, and the chain drives the pipe to move. The inclined surface design of the buffer block allows the pipe to smoothly transition to the push block when it contacts the inclined surface. The height setting of the first guard plate and the second guard plate away from the bed can prevent the pipe from deflecting or falling during transportation, thereby ensuring the smooth progress of the loading process. The height setting of the second guard plate close to the bed can ensure that the second guard plate will not block the transportation of the pipe when the rear chuck pushes the pipe.

[0016] Optionally, the feeding follow-up mechanism includes a feeding main frame, a feeding lifting frame and a follow-up centering assembly. The feeding main frame is fixedly connected to the bed, the feeding lifting frame is located on a side of the feeding main frame close to the feeding machine, the feeding lifting frame is slidably connected to the feeding main frame in a vertical direction, a lifting cylinder is fixedly provided on the side wall of the feeding lifting frame, the telescopic shaft end of the lifting cylinder is fixedly connected to a roller seat, the roller seat is located above the feeding lifting frame, a guide shaft is fixed to the lower end of the roller seat, the guide shaft is slidably connected to the feeding lifting frame in a vertical direction, the upper end surface of the roller seat is rotatably connected to a second roller, the axial direction of the second roller is the same as the sliding direction of the slide plate, the follow-up centering assembly is located on a side of the feeding lifting frame close to the feeding machine, the follow-up centering assembly includes a base plate, a driving cylinder, a steel wire, two rotating wheels and two slide plates, the roller seat is away from One side of the loader is fixedly connected to the base plate, and in the vertical direction, the second roller is higher than the upper end surface of the base plate, and the wheel is rotatably connected to the base plate along its own axis at the side of the base plate close to the loader. The steel wire is used to connect the two wheels, and two pulling ear seats are fixed on the steel wire, and the two pulling ear seats are respectively located on the upper and lower sides of the wheel. The two pulling ear seats are respectively fixedly connected to the two slides, and the driving cylinder is fixedly connected to the base plate at the side of the base plate close to the loader, and the telescopic shaft end of the cylinder is fixedly connected to a slide, and the two slides are slidingly connected to the base plate in opposite directions in the horizontal direction. The axis of the wheel extends in the horizontal direction and is perpendicular to the sliding direction of the slide, and the slide is rotatably connected to a clamping roller with an axis extending in the vertical direction, and the clamping roller is located between the two slides, and the highest end of the clamping roller is higher than the highest point of the second roller in the vertical direction.

[0017] By adopting the above technical solution, when the feeder conveys the pipe between the two clamping rollers, the telescopic shaft of the lifting cylinder extends upward, driving the roller seat to rise, so that the second roller abuts against the pipe on the feeder, and the rise of the roller seat drives the follow-up centering component to rise synchronously. The telescopic shaft of the driving cylinder contracts and drives one of the slides to slide in the horizontal direction, and the slide drives the pull ear seat fixedly connected to it to move. The pull ear seat is fixedly connected to the steel wire. Due to the cooperation of the steel wire and the two rotating wheels, the two pull ear seats move along the rotation trajectory of the steel wire. The two pull ear seats are located on the upper and lower sides of the rotating wheel, so that the two pull ear seats move in opposite directions in the horizontal direction, so that the two slides connected to different pull ear seats slide in opposite directions, and then drive the two slides to approach each other, so that the two clamping rollers can accurately clamp the pipe and realize the centering operation of the pipe. The whole process is stable and reliable, and easy to operate automatically. After the two clamping rollers clamp the pipe in the center, the loading lifting frame then slides upward to drive the pipe to a height corresponding to the clamping height of the rear chuck. The rear chuck pushes the pipe into the front chuck. The clamping rollers always clamp the pipe during the conveying process. The pipe can move smoothly along the second roller and the clamping rollers during the conveying process, thereby improving the stability and conveying efficiency of the pipe during the conveying process.

[0018] Optionally, the front chuck includes a chuck base, a turntable, two first rollers and two second rollers. The chuck base is slidably connected to the bed, the turntable is rotatably connected to the chuck base along its own axis, a square through hole is opened in the center of the turntable, the two first rollers and the two second rollers are all arranged along the circumference of the turntable, the first roller and the second roller are vertically arranged, the first roller and the second roller are respectively slidably connected to the turntable on the side of the turntable away from the rear chuck in a direction perpendicular to its own axis, the sliding directions of the two first rollers are opposite, and the sliding directions of the two second rollers are opposite.

[0019] By adopting the above technical solution, the pipe passes through the positive direction through hole, and the two first rollers and the two second rollers slide on the turntable to clamp the pipe respectively, and then the turntable drives the pipe to rotate so that the cutting device can cut the pipe. The front chuck can adapt to square pipes of different sizes, ensuring the stability and positioning accuracy of the pipe during the cutting process, while achieving effective clamping and follow-up support for the pipe, further improving the cutting accuracy and efficiency.

[0020] Optionally, a feed cart is provided below the cutting device.

[0021] By adopting the above technical solution, waste materials at the head and tail of the pipe during cutting and waste chips generated during cutting can be conveniently collected and transported by a material cart, thereby improving the continuity and production efficiency of the cutting process.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The operator places the pipe to be processed on the end of the loading device away from the bed. The loading device transports the pipe between the front chuck and the rear chuck. The rear chuck clamps the pipe and pushes the pipe to move toward the front chuck. Then one end of the pipe passes through the front chuck and slides on the first roller. The unloading device supports the pipe. The front chuck clamps the pipe and the cutting device cuts the pipe. While cutting, the front chuck drives the pipe to rotate. When the square pipe rotates, the distance between the outer wall of the square pipe and the first roller changes. The unloading lifting frame drives the support plate and the first roller to slide on the unloading main frame in the vertical direction to adapt to this distance change. The support plate and the first roller slide up and down with the rotation of the pipe and can also adapt to pipes of different diameters to improve cutting accuracy. After the cutting device has finished cutting, the unloading device moves to a position away from the rear chuck, so that the unloading device and the cut pipe on the unloading device are out of the range of the cutting device, so that when the pallet is turned over to unload, it is avoided that the cutting device is collided during unloading, thereby causing damage to the equipment. At the same time, it is convenient to place a box for storing the cut pipe on the side of the unloading device away from the bed. After the pipe cutting is completed, the turning cylinder can drive the pallet and the first roller to turn over, and the pipe carried on the first roller can be unloaded, thereby improving the unloading efficiency; 2. The front chuck is slidably connected to the bed along the conveying direction of the pipe, and the unloading main frame is fixedly connected to the front chuck, so that the front chuck can slide synchronously according to the conveying position of the pipe, thereby ensuring the stability and accuracy of the pipe during the cutting process. At the same time, the fixed connection between the unloading main frame and the front chuck ensures the relative position relationship between the unloading device and the front chuck, further improving the cutting accuracy and stability; 3. The sliding cylinder fixed on the bed can drive the front chuck to move along the conveying direction of the pipe, achieving precise positioning and stable support, thereby improving the accuracy and stability of the pipe cutting process. The axis direction of the sliding cylinder is the same as the conveying direction of the pipe, ensuring that the front chuck can accurately follow the movement of the pipe, further improving the cutting accuracy.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiment of the present application discloses a novel side-mounted two-chuck pipe cutting machine.

[0036] Reference Figure 1 A novel side-mounted two-chuck pipe cutting machine includes a bed 1, a front chuck 2, a rear chuck 3, a cutting device 4, a loading device 5 and a unloading device 6. The front chuck 2, the rear chuck 3, the cutting device 4, the loading device 5 and the unloading device 6 are all located on the same side of the bed 1.

[0037] Reference Figure 1The rear chuck 3 is slidably connected to the bed 1 along the conveying direction of the pipe, and is used to clamp the pipe to be processed and push the pipe to move toward the cutting device 4. The rear chuck 3 can be a four-jaw chuck, which can clamp irregular or non-circular pipes, such as elliptical, polygonal, etc., providing a more flexible clamping method.

[0038] Reference Figure 1 The feeding device 5 includes a plurality of feeders 51 and a plurality of feeder follower mechanisms 52. The plurality of feeders 51 synchronously transport the pipe from the end away from the bed 1 to the top of the feeder follower mechanism 52 along a direction perpendicular to the pipe conveying and cutting direction, so as to realize the stable conveying of the pipe; the feeder follower mechanism 52 is located on the side of the feeder 51 away from the unloading device 6 and close to the bed 1. The plurality of feeder follower mechanisms 52 simultaneously perform centering operations on the pipe, so as to realize the automatic centering of the pipe, thereby improving the feeding efficiency and cutting accuracy. The plurality of feeders 51 and the plurality of feeder follower mechanisms 52 are arranged one by one along the pipe conveying and cutting direction, that is, each feeder 51 is provided with a feeder follower mechanism 52 on the side away from the unloading device 6.

[0039] Reference Figure 2 A first guard plate 54 and a second guard plate 55 are arranged on one side of the bed 1 close to the loader 51 along the direction of pipe conveying and cutting. Several loaders 51 are located between the first guard plate 54 and the second guard plate 55. The first guard plate 54 is detachably connected to the bed 1 by bolts, and the second guard plate 55 is fixedly connected to the bed 1. The position of the first guard plate 54 can be adjusted so that the distance between the first guard plate 54 and the second guard plate 55 is adapted to the length of the pipe.

[0040] Reference Figure 3 The feeder 51 includes a feeder frame 511, a chain 512 and a pusher block 513. Two sprockets are arranged in the feeder frame 511. The two sprockets rotate synchronously through the chain 512. The lower end of the chain 512 is located in the feeder frame 511, and the upper end of the chain 512 is located above the feeder frame 511. Two buffer blocks 53 are arranged on the upper end surface of the feeder frame 511 and at one end away from the bed 1. The two buffer blocks 53 are arranged along the direction of pipe conveying and cutting. The pipe is placed on the buffer blocks 53 through a hoisting device. The buffer blocks 53 can be made of nylon.

[0041] Reference Figure 4The pusher blocks 513 are evenly arranged on the chain 512 along the transmission direction of the chain 512. The chain 512 drives the pusher blocks 513 to move. The pusher blocks 513 are used to push the pipe from the side of the feeder 51 away from the bed 1 to the direction of the feed follower mechanism 52. The upper end of the buffer block 53 close to the bed 1 is provided with an inclined surface 531. The height of the inclined surface 531 gradually decreases along the direction close to the bed 1. The upper end surface of the buffer block 53 is lower than the upper end surface of the pusher block 513 in vertical height. The lowest point of the inclined surface 531 is not higher than the highest point of the chain 512 in vertical height. The design of the inclined surface 531 of the buffer block 53 allows the pipe to smoothly transition to the pusher block 513 when it contacts the inclined surface 531.

[0042] Reference Figure 2 and Figure 3 The upper end surfaces of the first guard plate 54 and the second guard plate 55 at one end away from the bed 1 are higher than the upper end surface of the pusher block 513 in vertical height, preventing the pipe from being deflected or falling during the conveying process, thereby ensuring the smooth progress of the feeding process. The upper end surfaces of the first guard plate 54 and the second guard plate 55 at one end close to the bed 1 are not higher than the highest point of the chain 512 in vertical height, which can ensure that the second guard plate 55 will not block the conveying of the pipe when the rear chuck 3 pushes the pipe. A switch button can be installed on the side of the second guard plate 55 away from the feeder 51 to control the feeder 51 and the feed follower mechanism 52.

[0043] Reference Figure 5 and Figure 6 The feeding follower mechanism 52 includes a feeding main frame 521, a feeding lifting frame 522 and a follower centering component 523. The feeding main frame 521 is fixedly connected to the bed 1. The follower centering component 523 is located on the side of the feeding lifting frame 522 close to the loader 51. The follower centering component 523 includes a base plate 5231, a driving cylinder 5232, a steel wire 5233, two rotating wheels 5234 and two slides 5235. The slide 5235 is rotatably connected to a clamping roller 528 whose axis extends in a vertical direction. The clamping roller 528 is located between the two slides 5235. The loader 51 transports the pipe between the two clamping rollers 528.

[0044] Reference Figure 5 A lifting cylinder is fixedly provided on the side wall of the feeding lifting frame 522, and a roller seat 525 is fixedly connected to the end of the telescopic shaft of the lifting cylinder. The roller seat 525 is located above the feeding lifting frame 522. The telescopic shaft of the lifting cylinder extends upward, driving the roller seat 525 to rise, so that the second roller 526 abuts against the pipe on the feeding machine 51. A guide shaft is fixed to the lower end of the roller seat 525, and the guide shaft is slidably connected to the feeding lifting frame 522 in the vertical direction to improve the stability of the lifting of the roller seat 525. The upper end surface of the roller seat 525 is rotatably connected to the second roller 526, and the axial direction of the second roller 526 is the same as the sliding direction of the slide plate 5235.

[0045] Reference Figure 1 and Figure 7 The roller seat 525 is fixedly connected to the bottom plate 5231 at one side away from the feeder 51, and the lifting of the roller seat 525 drives the bottom plate 5231 to rise and fall synchronously. The second roller 526 is higher than the upper end surface of the bottom plate 5231 in the vertical direction, ensuring that the bottom plate 5231 will not cause obstruction when the pipe moves on the second roller 526.

[0046] Reference Figure 6 The rotating wheel 5234 is rotatably connected to the bottom plate 5231 along its own axis at the side of the bottom plate 5231 close to the loader 51, and the steel wire 5233 is used to connect the two rotating wheels 5234. Two pulling ear seats 527 are fixedly provided on the steel wire 5233. The two pulling ear seats 527 are respectively located on the upper and lower sides of the rotating wheel 5234. The two pulling ear seats 527 are respectively fixedly connected to the two slide plates 5235. The driving cylinder 5232 is fixedly connected to the bottom plate 5231 at the side of the bottom plate 5231 close to the loader 51, and the telescopic shaft end of the cylinder is fixedly connected to a slide plate 5235. The two slide plates 5235 are slidably connected to the bottom plate 5231 in opposite directions in the horizontal direction. The axis of the rotating wheel 5234 extends in the horizontal direction and is perpendicular to the sliding direction of the slide plate 5235. The highest end of the clamping roller 528 is higher than the highest point of the second roller 526 in the vertical direction.

[0047] Reference Figure 5 The loading lifting frame 522 is located on the side of the loading main frame 521 close to the loading machine 51, and the loading lifting frame 522 is slidably connected with the loading main frame 521 in the vertical direction. The specific way of sliding the loading lifting frame 522 is to set a motor and a lead screw under the loading main frame 521, and the lead screw is rotatably connected with the loading main frame 521 along the vertical axis. The motor drives the lead screw to rotate through a synchronous wheel and a synchronous belt. A nut seat is provided on the loading lifting frame 522, and the lead screw is threadedly connected with the nut seat, so that the rotation of the lead screw drives the loading lifting frame 522 to slide up and down. At the same time, a slide rail is provided on the side of the loading main frame 521 close to the loading lifting frame 522, and a slider sliding on the slide rail is provided on the loading lifting frame 522. The cooperation of the slide rail and the slider can improve the stability of the loading lifting frame 522 during the sliding process.

[0048] Reference Figure 5 When the loading lifting frame 522 slides upward to drive the pipe to a height corresponding to the clamping height of the rear chuck 3, the rear chuck 3 pushes the pipe into the front chuck 2. The clamping roller 528 always clamps the pipe during the conveying process. The pipe can move smoothly along the second roller 526 and the clamping roller 528 during the conveying process, thereby improving the stability and conveying efficiency of the pipe during the conveying process.

[0049] Reference Figure 3 and Figure 8The front chuck 2 includes a chuck base 21, a rotating disk 22, two first rollers 23 and two second rollers 24. The chuck base 21 is slidably connected to the bed 1 to provide support for the entire front chuck 2. A sliding cylinder 11 is fixedly arranged on the bed 1. The telescopic shaft end of the sliding cylinder 11 is fixedly connected to the front chuck 2. The axial direction of the sliding cylinder 11 is the same as the conveying direction of the pipe. The sliding cylinder 11 can use a hydraulic cylinder or a pneumatic cylinder as a power source and is fixed to the bed 1 by welding or bolts. The telescopic shaft is fixedly connected to the front chuck 2 to ensure that the front chuck 2 can slide on the bed 1 along the axial direction of the sliding cylinder 11, thereby realizing precise positioning of the pipe.

[0050] Reference Figure 8 A square through hole is opened in the center of the turntable 22, and the rear chuck 3 drives the pipe to pass through the through hole. The turntable 22 is rotatably connected to the chuck base 21 along its own axis. The turntable 22 can drive the pipe to rotate so that the cutting device 4 can cut the pipe.

[0051] Reference Figure 8 The two first rollers 23 and the two second rollers 24 are arranged along the circumference of the turntable 22. The first rollers 23 and the second rollers 24 are vertically arranged. The first rollers 23 and the second rollers 24 are respectively slidably connected to the turntable 22 on the side of the turntable 22 away from the rear chuck 3 in a direction perpendicular to their own axes. The sliding directions of the two first rollers 23 are opposite, and the sliding directions of the two second rollers 24 are opposite. The two first rollers 23 and the two second rollers 24 slide and clamp the pipe on the turntable 22, so that the front chuck 2 can adapt to square pipes of different sizes, ensure the stability and positioning accuracy of the pipe during the cutting process, and realize effective clamping and follow-up support of the pipe, further improving the cutting accuracy and efficiency.

[0052] Reference Fig. 9 A trolley 7 is provided under the cutting device 4, which can conveniently collect the chips and other waste generated during the cutting process. The trolley 7 is provided with a tray and wheels. The tray can be made of stainless steel to reduce the adhesion of chips while bearing the weight. The wheels can be made of rubber wheels to reduce noise and facilitate the transportation and cleaning of the collected waste.

[0053] Reference Figure 1 The cutting device 4 is fixedly connected to the bed 1, the loading device 5 and the unloading device 6 are arranged on both sides of the cutting device 4 along the conveying direction of the pipe, the front chuck 2 is located on the side of the unloading device 6 close to the loading device 5, and the rear chuck 3 is located on the side of the front chuck 2 away from the unloading device 6.

[0054] Reference Fig. 9The unloading device 6 includes an unloading main frame 61, an unloading lifting frame 62, a support plate 63, a flip cylinder 64, and a plurality of first rollers 65. The unloading main frame 61 is fixedly connected to the front chuck 2, and the front chuck 2 can drive the unloading device 6 to slide synchronously, thereby ensuring the relative position relationship between the unloading device 6 and the front chuck 2, and further improving the cutting accuracy and stability.

[0055] Reference Fig.10 The material unloading lifting frame 62 is slidably connected with the material unloading main frame 61 in the vertical direction. The specific way of sliding the material unloading lifting frame 62 is to set a motor and a lead screw under the material unloading main frame 61. The lead screw is rotatably connected with the material unloading main frame 61 along the vertical axis. The motor drives the lead screw to rotate through a synchronous wheel and a synchronous belt. A nut seat is provided on the material unloading lifting frame 62. The lead screw is threadedly connected with the nut seat, so that the rotation of the lead screw drives the material unloading lifting frame 62 to slide up and down. At the same time, a slide rail is provided on the side of the material unloading main frame 61 close to the material unloading lifting frame 62, and a slider sliding under the slide rail is provided under the material unloading lifting frame 62. The cooperation of the slide rail and the slider can improve the stability of the material unloading lifting frame 62 during the sliding process.

[0056] Reference Fig. 9 , several first rollers 65 are evenly arranged along the conveying direction of the pipe, and the first rollers 65 are rotatably connected to the support plate 63 in a direction perpendicular to the conveying direction of the pipe, and one side of the first roller 65 is located outside the support plate 63 in the circumferential direction. The rear chuck 3 pushes the pipe to pass through the front chuck 2, and the material unloading lifting frame 62 rises upward, so that the first roller 65 supports the pipe. The cutting device 4 cuts the pipe, and the front chuck 2 drives the pipe to rotate at the same time. When the irregular-shaped pipes such as square pipes rotate, the distance between the outer wall of the square pipe and the first roller 65 changes. The material unloading lifting frame 62 drives the support plate 63 and the first roller 65 to slide on the unloading main frame 61 in the vertical direction, which can adapt to this distance change. The support plate 63 and the first roller 65 slide up and down with the rotation of the pipe, which can also adapt to pipes of different diameters and improve the cutting accuracy.

[0057] Reference Fig.10 After the cutting device 4 completes the cutting, the unloading device 6 moves to a position away from the rear chuck 3, so that the unloading device 6 and the cut pipe on the unloading device 6 are out of the range of the cutting device 4, so that the pallet 63 is turned over to unload, avoiding collision with the cutting device 4 during unloading, thereby causing damage to the equipment, and at the same time facilitating the placement of a box for storing the cut pipes on the side of the unloading device 6 away from the bed 1. The cylinder body of the flip cylinder 64 is rotatably connected to the unloading lifting frame 62, the end of the pallet 63 away from the bed 1 is rotatably connected to the telescopic shaft end of the flip cylinder 64, and the end of the pallet 63 close to the bed 1 is rotatably connected to the unloading lifting frame 62. The flip cylinder 64 can drive the pallet 63 and the first roller 65 to flip, and the pipe carried on the first roller 65 can be unloaded, thereby improving the unloading efficiency.

[0058] Reference Fig.10 The turning cylinder 64 includes a cylinder body, a telescopic shaft, a piston and a seal. The cylinder body is rotatably connected to the unloading lifting frame 62, and the telescopic shaft is rotatably connected to the supporting plate 63. The cylinder body can be made of aluminum alloy to reduce weight. The telescopic shaft can be made of steel shafts of different diameters to meet different load requirements. The piston can be made of composite materials to improve wear resistance. The seal is made of Teflon or other materials with wear resistance to ensure a good sealing effect.

[0059] Reference Fig.10 The support plate 63 includes a main board and a support frame. The end of the support frame away from the bed 1 is rotatably connected to the telescopic shaft end of the flip cylinder 64, and the end of the support frame close to the bed 1 is rotatably connected to the unloading lifting frame 62.

[0060] The implementation principle of a new side-mounted two-chuck pipe cutting machine in the embodiment of the present application is as follows: the operator places the pipe to be processed on the end of the loading device 5 away from the bed 1, and the loading device 5 transports the pipe between the front chuck 2 and the rear chuck 3. The rear chuck 3 clamps the pipe and pushes the pipe to move to the front chuck 2. Then one end of the pipe passes through the front chuck 2 and slides on the first roller 65, and the unloading device 6 supports the pipe; the front chuck 2 clamps the pipe, and the cutting device 4 cuts the pipe. While cutting, the front chuck 2 drives the pipe to rotate. When the square pipe rotates, the distance between the outer wall of the square pipe and the first roller 65 changes. The unloading lifting frame 62 drives the support plate 63 and the first roller 65 to slide on the unloading main frame 61 in the vertical direction, which can adapt to this distance change. The support plate 63 and the first roller 65 slide up and down with the rotation of the pipe and can also adapt to pipes of different diameters, thereby improving the cutting accuracy. After the cutting device 4 completes cutting, the unloading device 6 moves to a position away from the rear chuck 3, so that the unloading device 6 and the cut pipe on the unloading device 6 are out of the range of the cutting device 4, so that when the support plate 63 is turned over for unloading, it is avoided that the cutting device 4 is collided during unloading, thereby causing damage to the equipment, and at the same time, it is convenient to place a box for storing the cut pipe on the side of the unloading device 6 away from the bed 1. After the pipe cutting is completed, the turning cylinder 64 can drive the support plate 63 and the first roller 65 to turn over, and the pipe carried on the first roller 65 can be unloaded, thereby improving the unloading efficiency.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
