Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment technology, and in particular to a dual-station pipe cutting device. Background Technology

[0002] Pipes, as a fundamental material of modern industry, are widely used in many fields such as machinery manufacturing, automobile manufacturing, construction engineering, petrochemicals, municipal water supply and drainage, and furniture production. However, pipes leaving the factory are usually of standardized length and specifications, which cannot directly meet the actual needs of various fields. They need to undergo further processing such as cutting, chamfering, deburring, tapping, welding, or bending before they can be put into use.

[0003] With the continuous improvement of industrial automation, servo equipment has been gradually adopted in many pipe processing stages. Servo motors drive processes such as pipe conveying, positioning, and cutting, improving processing efficiency and positioning accuracy to a certain extent, and reducing the labor intensity of manual operation. This has become an important component of current pipe processing production lines. However, existing servo pipe processing equipment generally suffers from complex structures, large footprints, and the integration of numerous transmission mechanisms, control components, and auxiliary devices, resulting in a bulky overall layout and requiring significant factory space, thus increasing manufacturing and maintenance costs.

[0004] Therefore, those skilled in the art are dedicated to developing a dual-station pipe cutting device that facilitates automatic pipe processing and has high operating efficiency and a compact structure. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a dual-station pipe cutting device that facilitates automatic pipe processing and has high operating efficiency and compact structure.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a dual-station pipe cutting device, comprising... Pipe feeding device; A pipe feeding device, located on the side wall of the pipe feeding device and used to deliver the pipes conveyed by the pipe feeding device to the next process; A pipe clamping and supporting device is installed on a base and located below the pipe feeding device, and is used to receive the pipes conveyed by the pipe feeding device. A clamping device for pipe cutting, wherein the clamping device for pipe cutting is mounted on a cutting machine base; A pipe cutting machine, wherein the pipe cutting machine is installed on the lower side of the base and located on the side wall of the cutting machine base; The control components are mounted on the cutting machine base and are electrically connected to the pipe feeding device, the pipe conveying device, the pipe clamping and supporting device, the pipe cutting clamping device, and the pipe cutting machine.

[0007] The beneficial effects of adopting the above solution are as follows: by modularly integrating and spatially optimizing the layout of the pipe feeding device, pipe conveying device, pipe clamping and support device, pipe cutting clamping device, pipe cutting machine and control components, the various processes such as feeding, conveying, clamping and support, cutting and clamping and cutting can work in a coordinated and orderly manner in a compact equipment space, reducing the requirements for factory space and the manufacturing and maintenance costs of the equipment. At the same time, it realizes the full-process automation of pipe feeding, precise delivery, stable clamping and support to automatic cutting, improving the operating efficiency and processing continuity of dual-station pipe cutting.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the pipe feeding device includes Feeding frame; Two horizontal moving components for feeding are installed on both sides of the feeding frame; A feeding limit component is installed on the moving end of the feeding horizontal moving component; A lifting assembly is installed on the side wall of the feeding frame and is used to lift the pipe.

[0010] The beneficial effects of adopting the above-mentioned further solution are: two feeding limit components respectively installed on the feeding horizontal moving component are arranged opposite each other and used to limit the storage position of the pipes. The feeding horizontal moving component is used to push the stacked pipes to the lifting position. The lifting component is used to lift the pipes one by one to the upper side of the feeding frame for subsequent clamping and movement.

[0011] Furthermore, the pipe feeding device includes Feeder frame; A feeding clamping assembly, two feeding clamping assemblies are arranged opposite each other and respectively mounted on the corresponding feeding frame, the feeding clamping assembly is connected to a horizontal feeding assembly, and the horizontal feeding assembly is mounted on the feeding frame; A feeding and clamping assembly, which is located above the horizontal feeding assembly; A feeding lifting assembly is installed on the feeding machine frame and the lifting end of the feeding lifting assembly is connected to the feeding clamping assembly.

[0012] The beneficial effects of adopting the above-mentioned further scheme are as follows: After the two oppositely arranged feeding clamping components clamp the pipe horizontally, they are transported in conjunction with the horizontal feeding component. The feeding clamping component, in conjunction with the feeding lifting component, realizes the vertical lifting and picking of the pipe, thereby forming a complete automated pipe feeding system. This system can effectively replace manual handling, significantly reduce labor intensity, improve feeding efficiency and position accuracy, and meet the requirements of modern production for automation and high efficiency.

A bidirectional clamping assembly is installed at the output end of the support lifting assembly, and a clamping element is connected to the output end of the bidirectional clamping assembly. A rolling support assembly is mounted on the side wall of the bidirectional clamping assembly.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the height of the support lifting component can be adjusted by the support height adjustment component to adapt to different pipe materials; the support lifting component is used to lift the bidirectional clamping component to quickly support the pipe material and clamp it bidirectionally through the clamping parts; the rolling support component provides rolling support to the bottom of the pipe material to share the weight of the pipe material and reduce axial movement resistance, thereby effectively suppressing the bending deformation of the pipe material caused by cutting force, clamping force and vibration force during the end processing, improving the flatness of the end face, dimensional accuracy and coaxiality, reducing secondary shaping processes, reducing production costs and improving overall processing efficiency.

[0015] Furthermore, the clamping device for pipe cutting includes First clamping assembly, two first clamping assemblies are arranged opposite to each other and slidably mounted on the chassis through a first guide assembly; The second clamping assembly consists of two second clamping assemblies arranged opposite to each other and spaced apart from the first clamping assembly.

The first driving component and the second driving component are spaced apart so that the first driving component and the second driving component move synchronously relative to each other to concentrically clamp the pipe. The clamping efficiency is high, the space occupied is small, and it is beneficial to subsequent processing.

[0017] Furthermore, the pipe cutting machine includes An end clamping assembly is mounted on the base via a translation assembly, which drives the end clamping assembly to move horizontally. A pipe fixing assembly is mounted on the cutting machine base and is disposed opposite to the end clamping assembly; A pipe cutting assembly is disposed on the side wall of the cutting machine base, and the pipe cutting assembly and the cutting machine base are connected by an adjustment assembly.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the end clamping assembly clamps the end of the pipe and moves along the base under the action of the horizontal moving assembly. After reaching the appropriate position, the pipe fixing assembly clamps the pipe, which facilitates the subsequent pipe cutting assembly to cut and process the pipe, thereby improving the processing efficiency and quality of the pipe.

[0019] Furthermore, the control component includes a controller and a control panel, the controller being mounted on the cutting machine base, and the control panel being mounted on the side wall of the controller and electrically connected to the controller.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the dust collection hood is installed above the cutting station of the pipe cutting machine, and under the continuous suction of the negative pressure fan, the metal dust and fumes generated during the cutting process are collected in a timely manner, reducing the diffusion and deposition of dust or fumes in the workshop environment.

[0023] Furthermore, a waste collection assembly is also installed on the lower side of the pipe cutting machine. The waste collection assembly includes a waste collection trough and a waste conveyor belt. The waste collection trough is located on the lower side of the pipe cutting machine, and the waste conveyor belt is located at the bottom of the collection trough.

[0024] The beneficial effects of adopting the above-mentioned further solution are: the waste collection tank is set under the pipe cutting machine, which can promptly receive the waste and debris that fall during the cutting and end processing.

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] like Figures 1 to 23 As shown, a dual-station pipe cutting device includes... Pipe feeding device 100; Pipe feeding device 200, located on the side wall of pipe feeding device 100 and used to deliver the pipes conveyed by pipe feeding device 100 to the next process; Pipe clamping support device 300 is mounted on base 320 and located below pipe feeding device 200, and is used to receive pipes conveyed by pipe feeding device 200. Pipe cutting clamping device 400, the pipe cutting clamping device 400 is on the cutting machine base 540; Pipe cutting machine 500 is installed on the lower side of base 320 and located on the side wall of cutting machine base 540; The control component 600 is mounted on the cutting machine base 540 and is electrically connected to the pipe feeding device 100, the pipe feeding device 200, the pipe clamping support device 300, the pipe cutting clamping device 400, and the pipe cutting machine 500.

[0033] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown in the figure, the pipe feeding device 100 includes a feeding frame 110; Two horizontal moving components 120 for feeding are installed on both sides of the feeding frame 110. The feeding limit component 130 is installed on the moving end of the feeding horizontal moving component 120; Lifting assembly 140 is mounted on the side wall of the feeding frame 110 and is used to lift the pipe.

[0034] During operation, the two horizontal moving components 120 synchronously drive the corresponding loading limit components 130 to move along the plane of the loading frame 110 to adjust the limit spacing and support the multi-layer stacked pipes, pushing the pipes layer by layer to the lifting station above the lifting component 140. Then the lifting component 140 lifts upward from the support gap, raising the bottom layer of pipes one by one to the support surface above the frame, so that the external clamping mechanism can grab and transfer them to the subsequent processing station, realizing the automated and orderly loading of pipes.

[0035] like Figure 2As shown, in some embodiments, the feeding frame 110 includes a crossbeam 111 and a longitudinal beam 112. Multiple crossbeams 111 and longitudinal beams 112 are connected by welding to form a rectangular frame with sufficient rigidity and load-bearing capacity. The side wall of the feeding frame 110 is also equipped with a limiting baffle 119. The limiting baffle 119 is specifically installed on the side wall of the crossbeam 111. The inner side of the limiting baffle 119 is opposite to the side of the pipe and is used to laterally block and limit the pipe during the placement and horizontal conveying of the pipe to prevent the pipe from slipping off the end of the frame. Support columns 113 are installed on the underside of the crossbeams 111 and longitudinal beams 112. The support columns 113 are distributed at each corner of the rectangular frame or evenly arranged along the length direction. They are used to lift the entire frame to a suitable working height and transfer the load to the ground. A height adjustment component is installed on the underside of the support column 113. By rotating the adjustment component, the support column 113 can be raised or lowered relative to the ground, thereby adaptively adjusting the overall level and height of the loading frame 110 according to the different work station heights and ground flatness in the production site.

[0036] In this embodiment, multiple spaced support beams 117 are installed between the two crossbeams 111. The support beams 117 are parallel to the longitudinal beams 112, and the upper surface of the support beams 117 is higher than the upper surfaces of the crossbeams 111 and the longitudinal beams 112, thus forming a spaced pipe support surface on the upper part of the frame. The gap between adjacent support beams 117 provides the necessary operating space for the lifting assembly 140 to lift the pipe upwards. The spacing of the support beams 117 is set according to the width of the lifting plate 146 to ensure that the lifting plate 146 can pass smoothly through the gap without interfering with the support beams 117. A smooth and wear-resistant slide strip 118 is also installed on the upper surface of the support beams 117. The smooth and wear-resistant slide strip 118 is made of polytetrafluoroethylene, nylon, or a low-friction coefficient material with surface hardening treatment. It is fixed to the upper end of the support beams 117 by bonding or countersunk screws, which can effectively reduce the frictional resistance when the pipe is pushed and moved on the support beams 117, reduce the wear on the pipe surface, and reduce the horizontal drive load.

[0037] like Figure 2 , Figure 3 and Figure 6 As shown, in one embodiment, the height adjustment assembly includes an adjustment plate 114. The adjustment plate 114 is installed at the bottom of the support column 113 and fits against the lower end face of the support column 113. The adjustment plate 114 is provided with a plurality of adjustment bolts 115, which are evenly distributed along the four corners of the adjustment plate 114. The upper end of the adjustment bolt 115 is threaded into the adjustment plate 114, and the other end of the adjustment bolt 115 is rotatably connected to the base plate 116, which is used to fix it to the ground or foundation. During adjustment, each adjustment bolt 115 is rotated to raise or lower the adjustment plate 114 relative to the base plate 116, thereby driving the support column 113 and the entire loading frame 110 to rise or fall until the upper surface of the frame reaches the required horizontal height. After adjustment, the position of the adjustment bolts 115 can be fixed by tightening the lock nuts to prevent loosening.

[0038] like Figure 2 , Figure 3 and Figure 6 As shown, in another embodiment, the feeding horizontal movement assembly 120 includes a feeding servo motor 121. The feeding servo motor 121 is fixed to the end of the feeding frame 110 via a motor mounting base. The output end of the feeding servo motor 121 is connected to a feeding lead screw 122 via a coupling. The feeding lead screw 122 is mounted on the feeding frame 110 via a feeding lead screw mounting base 123. A rolling bearing is installed inside the feeding lead screw mounting base 123 to support both ends of the feeding lead screw 122, enabling the feeding lead screw 122 to rotate smoothly around its own axis. A feeding lead screw bearing 124, which is a ball screw nut, is installed outside the feeding lead screw 122 to cooperate with it, converting the rotational motion of the feeding lead screw 122 into linear motion. A feeding slide rail 125 is also installed, which is located on the side wall of the feeding screw 122 and is set parallel to it. A feeding slider 126 that cooperates with the feeding slide rail 125 is installed on the feeding slide rail 125. The feeding slider 126 has embedded balls or rollers and can slide along the feeding slide rail 125 with low friction. A feeding limit component 130 is connected to the upper side of the feeding slide rail 125 and the feeding screw bearing 124. The feeding servo motor 121 accurately outputs the rotation angle according to the control command. Through the helical transmission of the feeding screw 122 and the feeding screw bearing 124, and in conjunction with the linear guidance of the feeding slide rail 125 and the feeding slider 126, the feeding limit component 130 can achieve precise and stable intermittent reciprocating movement in the horizontal direction, moving the multi-layer stacked pipes layer by layer or batch by batch to the lifting position.

[0039] like Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, the feeding limiting component 130 includes a feeding moving plate 131, which is connected to the feeding slider 126 and the feeding screw bearing 124 by bolts. A feeding support plate 132 is installed on the feeding moving plate 131, which extends horizontally to support the bottom of the pipe. A feeding limiting plate 133 is also installed between the feeding moving plate 131 and the feeding support plate 132. The feeding limiting plate 133 is vertically connected to both the feeding moving plate 131 and the feeding support plate 132. The feeding limiting plate 133 can be fixed to the feeding moving plate 131 and the feeding support plate 132 by welding or right-angle connectors. The three components together form a T-shaped limiting structure with lateral limiting and bottom support functions, which can stably clamp and limit the pipe during horizontal movement, prevent the pipe from axially shifting or laterally deviating, and ensure that multiple pipes can be neatly and synchronously transported to the designated work station.

[0040] like Figure 2 , Figure 4 and Figure 6As shown, in some embodiments, the lifting assembly 140 includes a lifting mounting plate 141, which is mounted on the side wall of the loading frame 110 and is perpendicular to the loading frame 110. Specifically, it can be vertically fixed to the outer side wall of the longitudinal beam 112 or the transverse beam 111 of the loading frame 110 by welding or high-strength bolts. A lifting servo motor 142 is mounted on the lifting mounting plate 141, and the lifting servo motor 142 is mounted on the lifting mounting plate 141 through a motor mount. The output end of the lifting servo motor 142 is connected to a lifting lead screw 14 via a coupling. 3. The lifting screw 143 is mounted on the lifting mounting plate 141 via a lifting screw mounting seat. The lifting screw mounting seat contains a bearing to support the lifting screw 143. A lifting screw bearing that mates with the lifting screw is mounted on the outside of the lifting screw 143. A lifting slide rail 144 is also mounted on the lifting mounting plate 141. The lifting slide rail 144 is located on the side wall of the lifting screw 143 and is arranged parallel to it. A lifting slider 145 that mates with the lifting slide rail 144 is mounted on the lifting slide rail 144. The lifting slider 145 and the lifting screw bearing are connected by a lifting plate 146. The lifting servo motor 142 drives the lifting screw 143 to rotate, and the rotational motion is converted into linear motion through the lifting screw bearing. The lifting slider 145 slides up and down along the lifting slide rail 144 to provide guidance and anti-overturning torque, so that the lifting plate 146 can achieve smooth and precise lifting and lowering motion in the vertical direction. It is used to lift the pipes one by one to a suitable position above the support beam 117 so that the subsequent clamping mechanism can grab and move them.

[0041] In other embodiments, for circular pipes, the lifting plate 146 is provided with a positioning groove. The groove shape is adapted to the outer contour of the circular pipe. A semi-circular groove or V-shaped groove matching the outer diameter of the pipe can be used, so that the lifting plate 146 can radially limit and support the pipe when lifting it, effectively preventing the pipe from rolling or slipping during the lifting process. In order to lift the circular pipes one by one, the width of the lifting plate 146 is greater than the diameter of a single pipe but less than the sum of the diameters of two pipes. This width limitation ensures that the lifting plate 146 can only support and lift one pipe at a time, avoiding jamming or misalignment caused by lifting multiple pipes at the same time. An intermediate plate is installed between the lifting slider 145 and the lifting screw bearing and the lifting plate 146. The intermediate plate is horizontally set and serves as a transition connector. The lifting plate 146 and the intermediate plate are hinged together. The hinge shaft is arranged horizontally and perpendicular to the pipe axis. A tension spring is installed between the lower side of the lifting plate 146 and the intermediate plate. One end of the tension spring is hooked on the spring bracket on the lower side of the lifting plate 146, and the other end is hooked on the corresponding bracket on the intermediate plate. A limit block is also installed on the intermediate plate. The limit block is located on the lower side of the lifting plate 146 and close to the hinge point. In normal operation, the lifting plate 146 abuts against the limiting block under the action of the tension spring, keeping the lifting plate 146 horizontal. The limiting block restricts the downward rotation limit of the lifting plate 146. When the lifting plate 146 moves downward, under the action of the stacked circular tubes, the front end of the lifting plate 146 is blocked by the tubes and rotates downward around the hinge point, stretching the tension spring. This allows the lifting plate 146 to pass the tubes. When it reaches the lowest point and there are no circular tubes blocking it, the lifting plate 146 returns to its horizontal position under the tension of the tension spring and abuts against the limiting block. When the lifting plate 146 moves upward, the positioning slot fits against the bottom of a single circular tube and positions it within the positioning slot before moving upward, thus completing the sequential lifting and feeding of a single tube.

[0042] like Figure 7 , Figure 8 and Figure 9 As shown, the pipe feeding device 200 includes a feeding frame 210, which serves as the basic support structure for the entire device, providing a stable installation foundation and bearing platform for each functional component. The feeding clamping assembly 220 consists of two feeding clamping assemblies 220 arranged opposite each other and mounted on corresponding feeding frames 210. The two feeding clamping assemblies 220 are symmetrically arranged along the length of the feeding frame 210 and clamp and position the pipe from both ends. The feeding clamping assembly 220 is connected to a horizontal feeding assembly 230, which is mounted on the feeding frame 210. The horizontal feeding assembly 230 provides the feeding clamping assembly 220 with a horizontal driving force and guiding constraint, so that the clamped pipe can achieve precise horizontal displacement along the longitudinal direction of the feeding frame 210. The feeding and clamping assembly 240 is located above the horizontal feeding assembly 230. The feeding and clamping assembly 240 is used to pick up and put down the pipe in the vertical direction, so as to realize the transfer of the pipe between different height stations. The feeding lifting assembly 250 is mounted on the feeding frame 210, and its lifting end is connected to the feeding clamping assembly 240. The feeding lifting assembly 250 provides vertical lifting drive force and guiding support to the feeding clamping assembly 240, enabling the feeding clamping assembly 240 to precisely lift and position the pipe in the vertical direction. During operation, the feeding clamping assembly 220 first horizontally clamps and fixes the pipe. The horizontal feeding assembly 230 drives the feeding clamping assembly 220 and the entire pipe to move horizontally to the designated work position. Then, the feeding lifting assembly 250 drives the feeding clamping assembly 240 to descend. After the feeding clamping assembly 240 clamps the pipe, the feeding clamping assembly 220 releases, and the feeding lifting assembly 250 rises to lift the pipe to the required height, completing the conversion of the pipe from a horizontal conveying state to a vertical picking and placing state, thereby achieving fast and accurate pipe feeding.

[0043] like Figure 7 and Figure 8 As shown, in some embodiments, the feeding frame 210 includes a feeding base 211 and a feeding gantry 212. The feeding base 211 adopts a frame or plate structure, and its bottom can be connected to the workshop floor or production line foundation platform by anchor bolts. The upper surface of the feeding base 211 is processed to ensure flatness. The feeding gantry 212 is installed in the middle of the feeding base 211 and is set perpendicular to the feeding base 211. The feeding gantry 212 is a portal frame structure composed of columns and beams. The lower end of the columns is connected to... The feeding base 211 is rigidly connected, and the crossbeam spans across the feeding base 211. The crossbeam of the feeding gantry 212 has multiple installation positions to support the feeding lifting assembly 250 and its driving load. Reinforcing ribs can be set between the columns and the crossbeam of the feeding gantry 212 to improve the bending stiffness and stability of the overall structure, so that the feeding frame 210 has both horizontal load-bearing capacity and vertical support capacity, ensuring that the entire feeding device maintains structural stability under high-speed operation and heavy-load conditions.

[0044] like Figure 7 and Figure 8As shown, in another embodiment, the feeding clamping assembly 220 includes a clamping plate 221. The clamping plate 221 is made of high-strength metal sheet, and its main body is elongated. The end of the clamping plate 221 is tapered. When the clamping plate 221 approaches the end of the pipe, the tapered end can be smoothly inserted into the hollow cavity of the pipe. The cooperation between the tapered surface and the end of the pipe achieves rapid centering and preliminary positioning. The lower side of the clamping plate 221 is mounted on the clamping moving plate 224 through a clamping slider 222 and a clamping slide rail 223. The clamping slide rail 223 is fixedly installed along the length direction of the clamping moving plate 224. The clamping slider 222 is fitted into the clamping slide rail 223 and can slide back and forth along the length direction of the clamping slide rail 223. The upper surface of the clamping slider 222 is fixedly connected to the lower surface of the clamping plate 221. Next, the clamping slide rail 223 and the clamping slider 222 are fitted with a precision linear guide rail, so that the clamping plate 221 can move smoothly along a predetermined linear trajectory when subjected to clamping driving force. The clamping moving plate 224 is installed on the horizontal feeding assembly 230. The clamping moving plate 224 serves as a transition connecting part between the clamping plate 221 and the horizontal feeding assembly 230. Its lower surface is fixedly connected to the feeding slider 232 in the horizontal feeding assembly 230. An mounting plate 225 is also installed on the clamping moving plate 224. The mounting plate 225 is set perpendicular to the clamping moving plate 224. A clamping cylinder 226 is installed on the side wall of the mounting plate 225. The front side of the clamping cylinder 226 is fixedly connected to the mounting plate 225. The output end of the clamping cylinder 226 is connected to the clamping plate 221 through a floating joint. When the piston rod of the clamping cylinder 226 extends, it pushes the clamping plate 221 to move along the clamping slide rail 223 toward the pipe until the conical end is tightly engaged with the pipe end and generates sufficient clamping force to fix the pipe. When the piston rod of the clamping cylinder 226 retracts, it pulls the clamping plate 221 to move in the opposite direction, causing the conical end to disengage from the pipe end, thus realizing the release action. The clamping moving plate 224, in conjunction with the horizontal feeding assembly 230, can drive the overall horizontal displacement of the clamped pipe, thereby making the clamping and horizontal conveying actions of the pipe continuous and reliable.

[0045] like Figure 7 and Figure 8As shown, in this embodiment, the horizontal feeding assembly 230 includes a feeding slide rail 231, which is a high-precision linear guide rail. The feeding slide rail 231 is horizontally mounted on the feeding frame 210. Specifically, the guide rail of the feeding slide rail 231 is fixedly mounted on the upper surface of the feeding base 211 along the length direction of the feeding base 211 by bolts. The feeding slide rail 231 is connected to the feeding clamping assembly 220 via a feeding slider 232. The feeding slider 232 is sleeved on the guide rail of the feeding slide rail 231 and can slide back and forth along the guide rail. The upper surface of the feeding slider 232 is fixedly connected to the lower surface of the clamping moving plate 224. The feeding slide rail 231 and the feeding slider 232 adopt a ball or roller linear guide rail structure, which is the feeding clamping assembly. The horizontal movement of component 220 provides precise linear guidance. A feeding rack 233 is also installed on the feeding frame 210. The feeding rack 233 is arranged along the length of the feeding base 211. The feeding rack 233 is parallel to the feeding slide rail 231. The tooth surface of the feeding rack 233 faces to the side. Both ends of the feeding rack 233 are fixed to the feeding base 211 by pressure blocks. A feeding servo motor 234 is installed on the feeding clamping assembly 220. The body of the feeding servo motor 234 is fixedly installed on the clamping moving plate 224 or mounting plate 225 by a motor base. The output end of the feeding servo motor 234 is connected to a feeding gear that cooperates with the feeding rack 233 through a coupling or key. The feeding gear and the feeding rack 233 are kept in a meshing state. When the feeding servo motor 234 receives the control command and starts running, the output shaft of the feeding servo motor 234 drives the feeding gear to rotate. The feeding gear meshes with the fixed feeding rack 233 to generate relative motion. Since the feeding rack 233 is fixed, the feeding gear moves along the extension direction of the feeding rack 233 while rotating, thereby driving the feeding servo motor 234 and the feeding clamping assembly 220 to move horizontally along the length direction of the feeding slide rail 231. The feeding servo motor 234 feeds back the position information in real time through the encoder, realizing precise closed-loop control of the horizontal displacement of the feeding clamping assembly 220, and can accurately transport the pipe to the designated work station according to the processing requirements.

[0046] like Figure 7 and Figure 9As shown, in one embodiment, the feeding clamping assembly 240 includes a bidirectional feeding cylinder 241. The bidirectional feeding cylinder 241 has two opposing piston rods, which can extend or retract synchronously under pneumatic drive. Clamping members 242 are installed at the output ends of the bidirectional feeding cylinder 241. The two clamping members 242 are fixedly connected to the ends of the two piston rods of the bidirectional feeding cylinder 241, respectively. When the bidirectional feeding cylinder 241 is ventilated, the two piston rods extend synchronously towards the center, pushing the two clamping members 242 to move towards each other, thereby applying clamping force symmetrically from both sides of the pipe, so that the pipe is securely clamped between the two clamping members 242. When the bidirectional feeding cylinder 241 is ventilated in the reverse direction, the two piston rods retract synchronously outward, driving... Two clamping elements 242 move in opposite directions to release the pipe. The clamping elements 242 are stepped, and the clamping surface of the clamping elements 242 has multiple steps of different heights along the vertical direction. Each step corresponds to a pipe of a certain diameter. When clamping pipes of different outer diameters, the outer wall of the pipe is in close contact with the step surface of the corresponding height. The vertical sidewall of the step surface plays a role in axial limiting and radial support for the pipe, so that the same set of clamping elements 242 can adapt to the clamping needs of pipes of various diameters. The inner sidewall of the clamping elements 242 is equipped with an anti-slip rubber layer, which is fixed to the clamping surface of the clamping elements 242 by bonding or embedding. The surface of the anti-slip rubber layer can be set with a grid-like or striped texture to increase the surface roughness.

[0047] When the clamping component 242 clamps the pipe, the anti-slip rubber layer is in direct contact with the outer wall of the pipe. The high coefficient of friction of the rubber material significantly increases the friction between the clamping component 242 and the surface of the pipe, effectively preventing the pipe from sliding or rotating due to its own weight or inertia during clamping and conveying. The feeding bidirectional cylinder 241 is installed on the feeding lifting assembly 250. The cylinder body of the feeding bidirectional cylinder 241 is fixedly connected to the lifting end of the feeding lifting assembly 250 through a bracket or connecting plate, so that the feeding clamping assembly 240 can rise and fall synchronously with the lifting action of the feeding lifting assembly 250, realizing the coordinated operation between the vertical picking and placing of the pipe and the horizontal conveying.

[0048] like Figure 7 and Figure 9As shown, in this embodiment, the feeding lifting assembly 250 includes a lifting seat 251. The lifting seat 251 has a through cavity and is mounted on the feeding gantry 212. The lifting seat 251 adopts a box-type structure, with a through cavity extending vertically through its middle section. The lifting seat 251 is fixedly mounted on the side wall of the crossbeam of the feeding gantry 212 by bolts. A lifting slider 252 is installed inside the through cavity. The lifting slider 252 is embedded in the inner wall of the through cavity and fixed by screws. The lifting slider 252 has a locking mechanism that engages with the lifting slider. The lifting slide rail 253, which mates with block 252, adopts a precision linear guide rail structure. The lifting slide rail 253 is arranged vertically, and its sidewall mates with the ball or roller circulation structure inside the lifting slider 252. The lifting slide rail 253 is mounted on the sidewall of the lifting column 254 and is fixed to the outer sidewall of the lifting column 254 by bolts. The lifting column 254 is a long, narrow column structure. The lifting column 254 is located between the lifting slide rail 253 and the lifting slider 252. Under the guidance constraint of column 254, it can only move vertically up and down. A lifting plate 257 is installed on the lower side of the lifting column 254 for connection with the feeding clamping assembly 240. The lifting plate 257 has a flat plate structure. The upper surface of the lifting plate 257 is fixedly connected to the lower end face of the lifting column 254 by welding or bolts. The lower surface of the lifting plate 257 is fixedly connected to the cylinder body of the feeding bidirectional cylinder 241 through a bracket or flange, thereby transmitting the vertical movement of the lifting column 254 to the feeding clamping assembly 240. A lifting rack 255 is also installed on the lifting column 254. The lifting rack 255 is fixed vertically to the side wall of the lifting column 254 by screws or pressure plates. The lifting rack 255 is arranged parallel to the lifting slide rail 253. A lifting servo motor 256 is installed on the lifting base 251. The body of the lifting servo motor 256 is fixed to the side wall of the lifting base 251 by a motor mounting bracket. The output end of the lifting servo motor 256 is directly connected to a lifting gear that meshes with the lifting rack 255. The lifting gear and the lifting rack 255 are engaged.

[0049] When the lifting servo motor 256 receives a control command to rise or fall, it starts to operate. The output shaft of the lifting servo motor 256 drives the lifting gear to rotate. The lifting gear meshes with the lifting rack 255 for transmission. Since the lifting rack 255 is fixedly connected to the lifting column 254, the rotational motion of the lifting gear is converted into the linear lifting motion of the lifting rack 255 and the lifting column 254. The lifting column 254 rises and falls smoothly under the precise guidance of the lifting slider 252 and the lifting slide rail 253. Thus, the lifting plate 257 drives the feeding clamping assembly 240 to achieve precise vertical positioning of the pipe, ensuring that the pipe can be accurately lifted to the specified height required for processing. The lifting servo motor 256 monitors the lifting displacement in real time through the encoder to achieve precise closed-loop control of the lifting height, completes the vertical conveying of the pipe and connects it to the subsequent process.

[0050] like Figure 10 , Figure 11 and Figure 12 As shown, the pipe clamping support device 300 includes a support height adjustment component 310, which is mounted on the base 320. The support height adjustment component 310 serves as the base height adjustment mechanism of the device and is used to make adaptive coarse adjustments to the overall support height according to the diameter specifications of the pipe to be processed and the height position of the processing center, so as to ensure that the subsequent support lifting component 330, bidirectional clamping component 340 and rolling support component 360 can be at the optimal support height that matches the pipe. The support lifting component 330 is connected to the output end of the support height adjustment component 310. After the support height adjustment component 310 completes the coarse height adjustment, the support lifting component 330 performs a rapid lifting action so that it can quickly lift to the support position when the pipe is transported to the processing area, or quickly lower and release the pipe after processing, so as to realize the rapid switching of the pipe support position. The bidirectional clamping assembly 340 is installed at the output end of the support lifting assembly 330. The output end of the bidirectional clamping assembly 340 is connected to the clamping member 350. The bidirectional clamping assembly 340 drives the clamping member 350 to approach and clamp the outer wall of the pipe symmetrically from both radial sides through the synchronous opposite movement of its two output ends, so as to realize automatic centering clamping of the middle part of the pipe to counteract the cutting force and vibration force that the pipe is subjected to during the end processing. The rolling support assembly 360 is installed on the side wall of the bidirectional clamping assembly 340. The rolling support assembly 360 provides upward rolling support from the bottom of the pipe and cooperates with the lateral clamping of the bidirectional clamping assembly 340 to form a multi-point support structure. While sharing the weight of the pipe, it transforms the sliding friction between the pipe and the support component into rolling friction, reducing the resistance when the pipe moves axially and improving the position adjustment efficiency.

[0051] like Figure 10 and Figure 11As shown, in some embodiments, the support height adjustment assembly 310 includes an adjustment servo motor (not shown in the figure) and an adjustment lifting plate 311. The adjustment servo motor is mounted on the base 320. An adjustment gear (not shown in the figure) is connected to the output end of the adjustment servo motor. An adjustment rack 312 that cooperates with the adjustment gear is connected to the output end of the adjustment servo motor. After receiving the pulse signal from the control system, the adjustment servo motor precisely drives the adjustment gear to rotate. The adjustment gear and the adjustment rack 312 mesh to form a gear and rack transmission pair, which converts the rotational motion of the adjustment servo motor into the linear displacement of the adjustment lifting plate 311 in the vertical direction. The precise setting of the support height of the adjustment lifting plate 311 is achieved through the angle closed-loop control of the servo motor. A first guide assembly is also installed between the adjustment lifting plate 311 and the base 320. Specifically, the first guide assembly provides vertical guidance constraint for the adjusting lifting plate 311 and bears the lateral force from the pipe, preventing the adjusting lifting plate 311 from tilting or shifting during lifting and support. The support lifting assembly 330 is installed on the adjusting lifting plate 311, and the support lifting assembly 330 adjusts its height reference position synchronously with the overall lifting of the adjusting lifting plate 311.

[0052] In this embodiment, the first guide component includes a support slider 313, which is installed on the side wall of the adjusting lifting plate 311. The support slider 313 engages with a support slide rail 315. The support slider 313 has a groove inside that matches the cross-sectional shape of the support slide rail 315. The support slide rail 315 is embedded in the groove of the support slider 313 to form a sliding pair. The support slide rail 315 is vertically installed on the base 320 through a connecting plate 314. The lower end of the connecting plate 314 is connected to the base 320 by bolts, and the upper end of the connecting plate 314 is fixed to the support slide rail 315 in the vertical direction, so that the support slide rail 315 stands vertically above the base 320 and provides a vertical guide reference for the adjusting lifting plate 311. A position sensor 316 is also installed on the adjusting lifting plate 311. The detection end of the position sensor 316 faces the connecting plate 314. The position sensor 316 detects the relative displacement change between the adjusting lifting plate 311 and the side wall of the connecting plate 314 in real time during the lifting process of the adjusting lifting plate 311 and feeds the detection signal back to the control system. When the position sensor 316 fails to detect the connecting plate 314, it indicates that the adjusting lifting plate 311 has reached its highest position. The control system accurately determines the current height position of the adjusting lifting plate 311 based on the feedback signal and controls the start and stop of the adjusting servo motor to achieve closed-loop control and precise positioning of the support height, avoiding over- or under-adjustment of the height.

[0053] like Figure 10 , Figure 11 and Figure 12As shown, in one embodiment, the support lifting assembly 330 includes a support cylinder 331, which is mounted on the adjusting lifting plate 311. The cylinder body of the support cylinder 331 is vertically fixed to the upper surface of the adjusting lifting plate 311 by a flange and bolts. The piston rod of the support cylinder 331 is arranged vertically and faces the pipe support position. The support cylinder 331 is supplied with air from an external compressed air source and the air passage is controlled by a solenoid valve. When the solenoid valve switches to the air intake position, compressed air enters the rodless chamber of the cylinder, pushing the piston rod to extend rapidly. When the solenoid valve switches to the exhaust position, the piston rod... The cylinder retracts under the action of air pressure difference and its own weight. The output end of the support cylinder 331 is connected to the bidirectional clamping assembly 340. The extension and retraction of the piston rod of the support cylinder 331 directly drives the bidirectional clamping assembly 340, its clamping parts 350 and the rolling support assembly 360 to rise and fall as a whole. A second guide assembly is installed between the bidirectional clamping assembly 340 and the adjusting lifting plate 311. The second guide assembly provides linear guidance to the bidirectional clamping assembly 340 during its rise and fall, ensuring that the bidirectional clamping assembly 340 maintains a stable horizontal posture during rapid rise and fall and when supported by force, thus avoiding swaying or tilting during the rise and fall process.

[0054] In this embodiment, the second guide component includes a lifting slider 332, which is mounted on an adjusting lifting plate 311. The lifting slider 332 is fixed to the upper surface of the adjusting lifting plate 311 by bolts. The lifting slider 332 is engaged with a lifting guide rail 333. A guide groove matching the cross-section of the lifting guide rail 333 is provided inside the lifting slider 332. The lifting guide rail 333 slides vertically through the guide groove of the lifting slider 332 and forms a precise sliding fit. The end of the lifting guide rail 333 is connected to the bidirectional clamping component 340. The upper end of the lifting guide rail 333 is fixedly connected to the mounting bracket 342 of the bidirectional clamping component 340 by threads. When the support cylinder 331 drives the bidirectional clamping component 340 to rise and fall, the lifting guide rail 333 slides precisely vertically in the guide groove of the lifting slider 332, providing a stable linear motion trajectory for the bidirectional clamping component 340 and bearing the lateral cutting force generated during the processing.

[0055] like Figure 10 , Figure 11 and Figure 12As shown, in this embodiment, the bidirectional clamping assembly 340 includes a bidirectional clamping cylinder 341. The bidirectional clamping cylinder 341 is connected to the output end of the support lifting assembly 330 via a mounting bracket 342. The mounting bracket 342 is a metal frame with sufficient structural rigidity. The bottom of the mounting bracket 342 is fixedly connected to the piston rod end of the support cylinder 331 and the upper end of the lifting guide rail 333. The bidirectional clamping cylinder 341 is fixedly mounted on the upper part of the mounting bracket 342 by bolts. The bidirectional clamping cylinder 341 has a double piston rod structure inside. Furthermore, the two piston rods extend symmetrically from both sides of the central cylinder. When compressed air enters from the central air inlet, the two piston rods extend outward synchronously under the action of air pressure. When compressed air enters from the two side air inlets, the two piston rods retract inward synchronously. The output end of the bidirectional clamping cylinder 341 is connected to a clamping component 350. The synchronous opposite or backward movement of the two piston rods ensures that the clamping components 350 on both sides simultaneously contact or detach from the outer wall of the pipe, thereby achieving automatic centering and clamping of the pipe and avoiding pipe displacement or tilting caused by contact on one side first. The clamping component 350 includes a clamping roller 351, which is vertically arranged. The rotation axis of the clamping roller 351 is arranged horizontally and perpendicular to the axial direction of the pipe. The clamping roller 351 is mounted on the output end of the bidirectional clamping cylinder 341 through a roller mounting bracket 352. One end of the roller mounting bracket 352 is rigidly connected to the piston rod end of the bidirectional clamping cylinder 341, and the other end of the roller mounting bracket 352 is mounted on the clamping roller 351 through a bearing. The outer circumferential surface of the clamping roller 351 can be coated with wear-resistant rubber or polyurethane to increase the friction coefficient with the outer wall of the pipe and protect the surface of the pipe. While providing radial clamping constraint, the rolling characteristics of the clamping roller 351 allow the pipe to move freely in the axial direction. It can effectively limit the middle of the pipe to prevent bending deformation, and will not hinder the axial feed or position adjustment of the pipe during processing.

[0056] In this embodiment, the rolling support assembly 360 includes a rolling support wheel 361. The rolling support wheel 361 is horizontally mounted on the mounting frame 342 via a support frame 362, which is an L-shaped metal bracket. One end of the support frame 362 is fixed to the side wall of the mounting frame 342 by bolts, and the other end of the support frame 362 is horizontally mounted on the rolling support wheel 361 via a bearing. The rolling support wheel 361 is covered with a wear-resistant and anti-slip layer. The rotation axis of the rolling support wheel 361 is arranged horizontally and parallel to the axial direction of the pipe. The outer peripheral surface of the rolling support wheel 361 is higher than the upper end surface of the bidirectional clamping cylinder 341, so that the rolling support wheel 361 can provide upward rolling support from the bottom of the pipe and move with the pipe. The lower surface of the outer wall of the pipe is in tangential contact, which transfers the self-weight load of the pipe to the mounting frame 342 and finally to the base 320 through the support lifting assembly 330 and the support height adjustment assembly 310. The rolling support wheel 361 and the clamping roller 351 cooperate to form a multi-point support structure for lateral clamping and bottom lifting. When the pipe end is subjected to cutting force, the rolling support wheel 361 and the clamping roller 351 jointly constrain the displacement freedom of the pipe, effectively suppressing the bending and deflection deformation of the middle part of the pipe. At the same time, the rolling characteristics of the rolling support wheel 361 transform the sliding friction when the pipe moves axially into rolling friction, reducing the axial movement resistance and improving the position adjustment efficiency and processing accuracy during pipe processing.

[0057] like Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the pipe cutting clamping device 400 includes a first clamping assembly 410. Two first clamping assemblies 410 are arranged opposite each other and slidably mounted on the chassis 431 through a first guide assembly 420. The two first clamping assemblies 410 are arranged radially opposite each other along the chassis 431 to form a first clamping station. The first guide assembly 420 constrains the first clamping assembly 410 to slide linearly back and forth only along the radial direction of the chassis 431, so that they can move synchronously relative to each other or in opposite directions under the drive of the first drive assembly 460 to clamp or release the pipe. The second clamping assembly 440 is arranged opposite to the first clamping assembly 410 and spaced apart. The second clamping assembly 440 is slidably mounted on the chassis 431 via the second guide assembly 450. The two second clamping assemblies 440 are arranged radially opposite to each other along the chassis 431 to form a second clamping station. The first clamping station and the second clamping station are distributed circumferentially along the chassis 431 to jointly form a dual-station clamping space for the pipe. The second guide assembly 450 constrains the second clamping assembly 440 to slide linearly back and forth only along the radial direction of the chassis 431, so that it can move synchronously relative to each other or in opposite directions under the drive of the second drive assembly 480 to clamp or release the pipe. The first drive assembly 460 is mounted on the mounting plate 432. The output end of the first drive assembly 460 is connected with two first clamping assemblies 410 via the first synchronization assembly 470. The first drive assembly 460 provides linear driving force and synchronously transmits the driving force to the two first clamping assemblies 410 through the first synchronization assembly 470, so that the two first clamping assemblies 410 move synchronously toward or away from each other to realize centering clamping or releasing of the first clamping station; The second drive assembly 480 is mounted on the mounting plate 432. The two first drive assemblies 460 and the two second drive assemblies 480 form four sides of a square shape. The output end of the second drive assembly 480 is connected with two second clamping assemblies 440 via the second synchronization assembly 490. The second drive assembly 480 provides linear driving force and synchronously transmits the driving force to the two second clamping assemblies 440 through the second synchronization assembly 490, so that the two second clamping assemblies 440 move synchronously toward or away from each other to realize centering clamping or releasing of the second clamping station.

[0058] As shown in Figure 1 , Figure 2 and Figure 3 , in some embodiments, the base plate 431 and the mounting plate 432 are arranged concentrically, and the base plate 431 and the mounting plate 432 are connected by connecting columns 434. The connecting columns 434 are arranged at uniform intervals along the circumferential direction of the base plate 431, and support and fix the base plate 431 and the mounting plate 432 into a double-layer disc-shaped frame structure with a constant spacing. The middle parts of the base plate 431 and the mounting plate 432 are both provided with through holes 433 for pipes to pass through. The through holes 433 are circular through holes and are coaxial with the base plate 431 and the mounting plate 432, so that the pipe to be processed can axially penetrate through the through holes 433 and form a concentric positioning relationship with the whole device, which is beneficial to keeping the pipe coaxial with the cutter during subsequent cutting processing.

[0059] As shown in Figure 13 , Figure 14 and Figure 15 , in another embodiment, each of the first clamping assembly 410 and the second clamping assembly 440 comprises a clamping roller 411. The clamping roller 411 is rotatably mounted on the clamping frame 412 through a wheel shaft. The outer circumferential surface of the clamping roller 411 is configured to directly contact the outer wall of the pipe and perform rolling friction relative to the outer wall of the pipe in the clamped state to reduce surface damage. The clamping frame 412 is a frame-type support structure, and the bottom of the clamping frame 412 is connected with the first guide assembly 420 or the second guide assembly 450, so that the clamping frame 412 drives the clamping roller 411 to slide accurately along the radial direction of the base plate 431 under the guidance of the guide assembly.

[0060] In this embodiment, the clamping frame 412 is equipped with an auxiliary clamping wheel 414 via an auxiliary mounting frame 413. The auxiliary mounting frame 413 extends laterally from the clamping frame 412 to form a cantilever support structure. The auxiliary clamping wheel 414 is rotatably mounted at the end of the auxiliary mounting frame 413 via a wheel axle and is located on the side wall of the clamping roller 411. The outer circular surface of the auxiliary clamping wheel 414 and the outer circular surface of the clamping roller 411 are on the same plane, so that the auxiliary clamping wheel 414 and the clamping roller 411 cooperate in the same plane perpendicular to the axial direction of the chassis 431 to form multi-point rolling clamping, thereby increasing the contact area between the clamping assembly and the outer wall of the pipe and dispersing the clamping stress, avoiding single-point clamping from causing indentations or deformation on the surface of the pipe.

[0061] like Figure 13 , Figure 14 and Figure 15 As shown, in one embodiment, both the first guide assembly 420 and the second guide assembly 450 include a guide block 421. The guide block 421 is a long strip-shaped metal slider and is fixedly connected to the bottom of the clamping frame 412. The guide block 421 has guide ribs 422 extending along its length on both sides. The guide ribs 422 are strip-shaped guide rail structures protruding from the sidewalls of the guide block 421. Guide wheels 423 are rotatably mounted on the chassis 431 via axles. The guide block 421 is located between the two guide wheels 423 and guides... The outer circumferential surface of the wheel 423 is provided with a guide groove 424 that cooperates with the guide rib 422. The guide groove 424 is a concave circumferential groove. The guide rib 422 is embedded in the guide groove 424 to form a sliding fit. The two guide wheels 423 clamp the guide block 421 from both sides and restrict it to slide linearly only along the radial direction of the chassis 431, thereby ensuring that the clamping frame 412 and the clamping roller 411 have high-precision linear guidance during reciprocating movement and preventing the clamping assembly from deflecting or jamming under force.

[0062] like Figure 13 , Figure 14 and Figure 15As shown, the first drive assembly 460 and the second drive assembly 480 include drive cylinders 461. Specifically, in this solution, both the first drive assembly 460 and the second drive assembly 480 include two drive cylinders 461. The two drive cylinders 461 are arranged opposite to each other and symmetrically about the center of the chassis 431 to provide a balanced clamping driving force. The cylinder body end of the drive cylinder 461 is hinged to the mounting plate 432 via a rotating rod 462. The piston rod output end of the drive cylinder 461 is hinged to a drive rod 463, which is a long strip-shaped force transmission link. The middle part of the drive rod 463 is rotatably connected to a first synchronization component 470 or a second synchronization component 490. The end of the drive rod 463 away from the middle is rotatably connected to a guide block 421 via a connector 464. The mounting plate 432 has an arc-shaped clearance groove 435 for the drive rod 463 to pass through and move. The arc-shaped clearance groove 435 is an arc-shaped through groove with the center of the fixed sleeve 472 as the center. Under the pushing and pulling action of the drive cylinder 461, the drive rod 463 swings back and forth along the arc-shaped trajectory of the arc-shaped clearance groove 435, thereby converting the linear reciprocating motion of the drive cylinder 461 into the fixed-axis swinging motion of the drive rod 463.

[0063] In this embodiment, the connector 464 is arc-shaped and serves as an arc-shaped force transmission link. One end of the connector 464 is vertically rotatably connected to the drive rod 463 via a pin, and the other end of the connector 464 is hinged to the guide block 421 via a connecting rod 465. The connecting rod 465 is a straight rod structure and is arranged vertically. The upper end of the connecting rod 465 is hinged to the connector 464, and the lower end is hinged to the guide block 421. The chassis 431 has a passage for the connecting rod 465 to pass through and move radially along the chassis 431. The moving groove 436 is a long strip-shaped through groove extending radially along the chassis 431. When the drive rod 463 swings under the action of the drive cylinder 461, the connecting member 464 transmits the swing motion of the drive rod 463 to the connecting rod 465. Under the guiding and limiting action of the moving groove 436, the connecting rod 465 converts the motion into the linear sliding of the guide block 421 along the radial direction of the chassis 431, thereby driving the clamping frame 412 and the clamping roller 411 to move centrifugally or centrifugally to complete the clamping or releasing action.

[0064] like Figure 13 , Figure 14 , Figure 17 and Figure 18As shown, in this embodiment, both the first synchronization component 470 and the second synchronization component 490 include a synchronization ring 471. The synchronization ring 471 is a circular structure and is sleeved on the outside of the fixed sleeve 472. The synchronization ring 471 and the fixed sleeve 472 are rotatably coupled through a bearing. The fixed sleeve 472 is fixedly installed in the middle of the mounting plate 432 through a flange and is located around the through hole 433. A rotating sleeve 473 for rotatably connecting with the drive rod 463 is provided on the outer circumference of the synchronization ring 471. The rotating sleeve 473 is a sleeve-shaped structure that radially protrudes from the outer wall of the synchronization ring 471. The middle part of the drive rod 463 passes through the rotating sleeve 473. A rotating hinge is formed, with two drive rods 463 symmetrically arranged on both sides of the synchronization ring 471 and connected to the synchronization ring 471 through rotating sleeves 473 respectively. When the drive cylinder 461 on one side pushes the corresponding drive rod 463 to swing, the drive rod 463 drives the synchronization ring 471 to rotate around the center of the fixed sleeve 472 through the rotating sleeve 473. The rotational motion of the synchronization ring 471 drives the symmetrically arranged drive rods 463 to swing in the opposite direction through the rotating sleeve 473 on the other side, thereby accurately ensuring that the two oppositely arranged first clamping components 410 or second clamping components 440 move synchronously in a centripetal or centrifugal motion, ensuring the centering and clamping of the pipe.

[0065] like Figure 19 , Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, the pipe cutting machine 500 includes an end clamping assembly 510. The end clamping assembly 510 is mounted on the base 320 via a translation assembly 520. The translation assembly 520 drives the end clamping assembly 510 to move horizontally. The end clamping assembly 510 is used to clamp the end of the pipe and moves horizontally along the base 320 under the drive of the translation assembly 520 to transport the pipe to the processing station at the cutting machine base 540. The pipe fixing assembly 530 is mounted on the cutting machine base 540 and is positioned opposite to the end clamping assembly 510. The pipe fixing assembly 530 is used to clamp and fix the middle part of the pipe during the cutting process to ensure that the pipe remains stable and does not shake during cutting and end processing. The pipe cutting assembly 550 is installed on the side wall of the cutting machine base 540. The pipe cutting assembly 550 and the cutting machine base 540 are connected by an adjustment assembly 560. The pipe cutting assembly 550 adjusts its cutting position and posture under the drive of the adjustment assembly 560 to achieve precise cutting of the pipe and processing of irregular end structures. The components cooperate with each other to complete the automatic feeding, clamping, cutting and end processing of the pipe.

[0066] like Figure 19 , Figure 20 and Figure 21As shown, in some embodiments, the end clamping assembly 510 includes a pneumatic rotary chuck 511. The pneumatic rotary chuck 511 has multiple pneumatic claws 512 at its end. The pneumatic claws 512 have anti-slip protrusions on their inner sides. The multiple pneumatic claws 512 are arranged circumferentially. The pneumatic rotary chuck 511 is mounted on the translation assembly 520. The pneumatic rotary chuck 511 has an internal air passage structure and is externally connected to an air source device. The pneumatic claws 512 are synchronously opened and closed by controlling the on / off state of the air source. The multiple pneumatic claws 512 are arranged at equal intervals along the circumferential direction to form a self-centering clamping structure. When the air source is supplied, each pneumatic jaw 512 moves synchronously towards the center, uniformly clamping the outer wall of the pipe from the circumferential direction, so that the axis of the pipe coincides with the rotation center of the pneumatic rotary chuck 511. The anti-slip protrusions on the inner side of the pneumatic jaw 512 are made of wear-resistant rubber or metal protrusions, which embed into the outer wall surface of the pipe during clamping to increase the friction coefficient of the contact surface and prevent the pipe from sliding relative to each other or rotating accidentally under the action of cutting torque and axial force. The bottom of the pneumatic rotary chuck 511 is fixedly connected to the translation plate 521. Driven by the rotary servo motor, it can drive the clamped pipe to rotate around its own axis, thereby adjusting the pipe to the required processing angle, which is convenient for chamfering, deburring or irregular cutting of the pipe end.

[0067] like Figure 19 and Figure 21As shown, in this embodiment, the translation assembly 520 includes a translation plate 521, a pneumatic rotary chuck 511 mounted on the translation plate 521, and a base 320 on the lower side of the translation plate 521 via translation sliders 522 and translation rails 523. The translation plate 521 is a rectangular metal plate structure, with its upper surface fixedly connected to the base of the pneumatic rotary chuck 511 by bolts, and its lower surface slidingly engaged with the translation rails 523 mounted on the base 320 via multiple translation sliders 522. The translation rails 523 are two parallel linear guide rails, and the translation sliders 522 have a ball or roller circulation structure inside, enabling the translation plate 521 to perform low-friction linear reciprocating motion along the translation rails 523. A translation servo motor 524 is also mounted on the translation plate 521. The servo motor 524 is fixed to one side of the translation plate 521 via a motor mount. The output end of the translation servo motor 524 is connected to a translation gear. A translation rack that cooperates with the translation gear is installed on the base 320. The translation rack is arranged parallel to the translation slide rail 523. When the servo motor 524 is powered on, the translation gear rolls on the translation rack to generate a linear driving force along the rack direction. The driving force is transmitted to the translation slider 522 through the translation plate 521, causing the translation slider 522 to slide along the translation slide rail 523. This drives the translation plate 521, the pneumatic rotary chuck 511 above it, and the entire pipe to move precisely in the horizontal direction. By controlling the speed and angle of the servo motor 524, the feed displacement of the pipe can be precisely controlled, so that the end of the pipe can accurately reach the cutting position or move out of the cutting position.

[0068] like Figure 19 , Figure 20 and Figure 22As shown, in one embodiment, the pipe fixing assembly 530 can adopt the same structure as the pipe cutting clamping device 400, or it can adopt the following structure. Specifically, the pipe fixing assembly 530 includes a fixing plate 531, the fixing plate 531 has a first material passage hole 532 in the middle, the fixing plate 531 is mounted on the cutting machine base 540, the fixing plate 531 has a disc-shaped structure and is coaxially fixed to the end face of the cutting machine base 540 facing the end clamping assembly 510 by a flange or bolts, and the first material passage hole 532 in the middle is circular or rectangular. The hole has a diameter larger than the maximum outer diameter of the pipe to be processed, so that the pipe can pass horizontally through one side of the end clamping assembly 510 and enter the processing area. The fixed plate 531 has multiple circumferentially arranged sliding grooves 533. The sliding grooves 533 are radially arranged T-shaped grooves or dovetail grooves, and matching fixed clamping members are engaged in them. The sliding grooves 533 play a radial guiding and limiting role for the fixed clamping members. The fixed clamping members are engaged in the sliding grooves 533. Each fixed clamping member is also connected to a synchronous rotation assembly, which includes a rotation servo motor 53. 5. A rotating ring is mounted on the side wall of the fixed disk 531 via a fixed cylinder. The fixed cylinder is a cylindrical structure, and one end is coaxially fixedly connected to the end face of the clamping assembly 510 at the opposite end of the fixed disk 531. The fixed cylinder has a second material passage hole communicating with the first material passage hole 532. The second material passage hole and the first material passage hole 532 are coaxially connected to form a continuous channel for the pipe to pass through. The outer side of the rotating ring has a rotating gear ring, which meshes with the rotating gear at the output end of the rotating servo motor 535 mounted on the side wall of the fixed disk 531. The rotating servo motor 535... 5. A rotating gear that meshes with a rotating gear ring is connected to the output end of a rotating servo motor 535 installed on the side wall of a fixed disk 531. The rotating ring is provided with multiple circumferential arc grooves. The arc grooves are elongated through holes and their length direction forms a certain angle with the radial direction of the rotating ring. A fixed rod passes through the arc groove. One end of the fixed rod is fixedly connected to a fixed clamping component. The end of the fixed rod is connected to a clamping component. The rotation of the rotating servo motor 535 drives the rotating gear, rotating gear ring and rotating ring to rotate in sequence, so that multiple fixed clamping components move closer to or away from the first material passage hole 532 simultaneously.

[0069] When the servo motor 535 starts, its output shaft drives the rotating gear to rotate. The rotating gear drives the rotating ring to rotate around the axis of the fixed cylinder through meshing with the rotating gear ring. When the rotating ring rotates, the side wall of the arc groove applies a radial thrust to the fixed rod. Since the fixed rod is constrained by the radial guidance of the sliding groove 533, it can only move radially within the sliding groove 533. Therefore, the rotational motion of the rotating ring is converted into the synchronous radial linear motion of the fixed clamping parts through the cooperation of the arc groove and the fixed rod, so that multiple fixed clamping parts simultaneously approach or move away from the center of the first material passage hole 532, thereby realizing the rapid automatic centering clamping of pipes of different diameters.

[0070] like Figure 22As shown, in this embodiment, the fixing clamp includes a fixing block 536, which is located within a sliding groove 533. The fixing block 536 is a slider structure that matches the cross-sectional shape of the sliding groove 533 and can slide radially along the sliding groove 533. A fixing frame 537 is connected to the fixing block 536. One end of the fixing block 536 facing the first feed hole 532 is fixedly connected to the fixing frame 537 by bolts. A rotating roller 538 is installed on the fixing frame 537. The fixing frame 537 is a U-shaped metal bracket, and its end away from the fixing block 536 extends towards the center of the first feed hole 532. The two side walls of the extended end are connected... A rotating roller 538 is rotatably mounted via a pin. The rotating roller 538 is a cylindrical roller with its outer circumferential surface being a plane adapted to the outer wall of the pipe. When the fixed clamping component moves towards the center of the first feed hole 532 to clamp the pipe under the drive of the synchronous rotating assembly, the outer circumferential surface of the rotating roller 538 contacts the outer wall of the pipe and generates a certain clamping force. When the pipe needs to move along its own axis, the rotating roller 538 can rotate freely around the pin, changing the sliding friction between the fixed clamping component and the outer wall of the pipe into rolling friction, reducing frictional resistance, and enabling the pipe to move smoothly axially while maintaining the clamped state.

[0071] like Figure 19 , Figure 20 and Figure 23 As shown, in one embodiment, the pipe cutting assembly 550 includes a laser cutter 551, or a plasma cutter. The laser cutter 551 is mounted on the adjustment assembly 560. The laser cutter 551 includes a laser generator, a laser head, a focusing lens, and a cooling system. The laser generator generates a high-energy-density laser beam, which is transmitted to the laser head through an optical path and focused into an extremely fine spot by the focusing lens, irradiating the surface of the pipe. This causes the pipe material to melt or vaporize in a very short time, thereby achieving non-contact cutting. This effectively improves the cutting efficiency and cut quality of the pipe. The laser cutter 551 is fixedly connected to the output end of the adjustment assembly 560 through a mounting plate. Under the drive of the adjustment assembly 560, the spatial position of the laser head can be adjusted in the vertical and horizontal directions.

[0072] In this embodiment, the adjustment component 560 includes a first linear motor 561, which is vertically arranged. The output end of the first linear motor 561 is connected to the pipe cutting component 550. When the first linear motor 561 is energized, the first moving part moves linearly relative to the first stator in the vertical direction, thereby driving the laser cutting machine 551 to move up and down to adjust the vertical distance between the laser head and the pipe surface, adapting to the cutting height requirements of pipes with different diameters. A second linear motor 562 is mounted on the cutting machine base 540, which is horizontally arranged. The output end of the second linear motor 562 is connected to the first linear motor 560. When the second linear motor 562 is energized, the second moving part moves in a straight line in the horizontal direction relative to the second stator, thereby driving the first linear motor 561 and the laser cutting machine 551 to move in the horizontal direction as a whole, so as to adjust the horizontal cutting position of the laser cutting machine 551 relative to the pipe axis. The first linear motor 561 and the second linear motor 562 are arranged perpendicularly to each other to form a two-dimensional rectangular coordinate motion system. By controlling the displacement of the two linear motors respectively, the laser cutting machine 551 can be accurately moved to any target position in the vertical plane, realizing the precise cutting and processing of different parts and irregular structures at the ends of the pipe.

[0073] In other embodiments, the control component 600 includes a controller and a control panel 601. The controller is mounted on the cutting machine base 540, and the control panel 601 is mounted on the side wall of the controller and electrically connected to the controller. The controller uses an industrial programmable logic controller as the core control unit, with a built-in dedicated control program and data storage module. It can preset a complete set of automated operation logic for pipe feeding, feeding, clamping, cutting, and resetting. It can receive real-time detection signals from sensors at each workstation and accurately output pulse control signals. In this way, it can coordinate and control the start, stop, speed, displacement, clamping force, and action sequence of the pipe feeding device 100, pipe feeding device 200, pipe clamping support device 300, pipe cutting clamping device 400, and pipe cutting machine 500, ensuring that the various mechanisms work together and operate in an orderly manner, effectively avoiding interference and misalignment in the actions of each process. At the same time, it can store processing parameters for various specifications of pipes, adapt to the production needs of different pipe diameters and different cutting lengths, and has the functions of parameter memory, fault self-checking, and data statistics.

[0074] The control panel 601 adopts an embedded touch screen structure with a wear-resistant and scratch-resistant protective layer on the screen surface. It integrates parameter setting interface, manual operation interface, automatic operation interface and fault alarm interface. Operators can complete equipment parameter debugging, single mechanism manual testing, fully automatic operation start and emergency stop through touch operation. The control panel 601 integrates a signal transmission module and an encrypted communication module. It establishes a stable electrical connection with the controller through a shielded cable. It can receive information such as equipment operating status, workstation position, processing progress and fault codes fed back by the controller in real time, realizing visualized real-time monitoring of equipment operating status.

[0075] The pipe cutting machine 500 is also equipped with a dust removal component, which includes a dust collection hood and a negative pressure fan. The dust collection hood is installed above the cutting station of the pipe cutting machine, and the negative pressure fan is connected to the dust collection hood. The dust collection hood adopts an integrated arc-shaped air collection hood structure, which is fixed to the outer frame of the pipe cutting component 550 by a detachable bracket. It covers the entire working area of ​​laser cutting or plasma cutting. The hood adopts a large opening and a tapered cavity design. The opening size completely covers the pipe cutting station, which can comprehensively wrap the smoke, metal dust and fine slag particles generated during the cutting operation, and prevent the dust and smoke from overflowing and spreading. The inner wall of the dust collection hood is smooth and has a guide slope, which can optimize the airflow direction and improve the dust collection and adsorption efficiency. At the same time, the edge of the hood fits the cutting operation area, which can effectively gather the high-temperature smoke generated instantly during the cutting process. The negative pressure fan is installed on the outside of the cutting machine base 540 in an empty space via a fixed frame. The air inlet of the negative pressure fan is sealed and connected to the dust collection port on the top of the dust hood through a sealed corrugated dust collection pipe. Sealing gaskets are installed at the pipe joints to prevent air leakage. The negative pressure fan has a built-in high-speed centrifugal impeller and a noise-reducing housing. During operation, it forms a stable negative pressure adsorption environment inside the dust collection hood cavity through high-speed rotation. It starts and runs synchronously with the pipe cutting assembly 550 when performing cutting operations. It uses negative pressure suction to suck metal dust, fumes, vaporized impurities and fine molten slag fragments generated during the cutting process into the pipe in real time and transport them to the external dust removal and purification equipment to complete the dust purification treatment. This effectively purifies the working environment and prevents metal dust from accumulating on the precision structural surfaces of the equipment guide rails, lead screws, clamping parts and other precision components, preventing dust from wearing precision parts and affecting the operating accuracy of the equipment.

[0076] The pipe cutting machine 500 is also equipped with a waste collection assembly on its lower side. The waste collection assembly includes a waste collection trough and a waste conveyor belt. The waste collection trough is located on the lower side of the pipe cutting machine 500, and the waste conveyor belt is located at the bottom of the collection trough. The waste collection trough adopts an integrated bent funnel-shaped trough structure, which is fixed to the bottom of the frame of the pipe cutting machine 500 by bolts and completely covers the area directly below the cutting station. The trough has a gradually narrowing structure from top to bottom. The large-sized upper end design can fully collect the pipe scraps, short pieces, slag waste and grinding debris that fall during the cutting operation. The inner wall of the trough is treated with smooth rust prevention to prevent metal waste from sticking and accumulating. At the same time, the two sides of the trough are equipped with material retaining edges to effectively prevent waste from falling into the gaps of the equipment frame or the ground, ensuring that the bottom of the equipment is clean. The waste conveyor belt adopts a metal belt conveyor structure, horizontally embedded and fixed at the bottom of the waste collection trough. Both ends of the conveyor belt are equipped with active rollers, driven rollers, and drive motors. The drive motors provide uniform conveying power to the conveyor belt through a reduction mechanism. The surface of the conveyor belt is decorated with anti-slip and wear-resistant textures and material-blocking protrusions, which can stably support cutting waste of various sizes. All waste generated by the equipment's cutting operation automatically falls into the waste collection trough under the action of gravity and settles on the surface of the waste conveyor belt. The conveyor belt continuously and uniformly transports the collected waste smoothly to the waste collection box outside the equipment, realizing the automated centralized collection and orderly transportation of cutting waste. There is no need for manual cleaning of waste at regular intervals, which effectively avoids waste accumulation affecting the normal operation of the equipment and scratching the precision parts of the equipment, greatly reducing the cost of manual cleaning, and adapting to the operation requirements of continuous automated cutting production.
