[0034] In actual application, the pipe to be cut is loaded to the rear end / upstream of the feeding assembly 5 by using the crane arm, and the feeding assembly 5 operates and gradually transports the pipes one by one to the front end / downstream, that is, it is located at the lifting position of multiple centering follower mechanisms 4, and the pipe to be cut is lifted to be coaxial with the first chuck structure 31 and the second chuck structure 32 by the centering follower mechanism 4, and the first chuck structure 31 and the second chuck structure 32 are moved to the set position and the pipe is clamped and fixed; then, the first chuck structure 31 pushes the pipe forward in the direction of the laser cutting assembly 2 to achieve cutting, and the cut pipe is clamped by the third chuck structure 33, and the follow-up support and auxiliary unloading are carried out with the cooperation of the receiving mechanism 6.

[0036] In the above arrangement, by opening a plurality of first wiring openings 102 and second wiring openings 103 at positions corresponding to the side-hanging bed 1, and coordinating with the positions of the feeding assembly 5 and the centering follower mechanism 4, the receiving assembly 7, and the receiving mechanism 6, the lines of the above mechanisms can be centrally processed.

[0037] See also Figure 1 and Figure 2In some embodiments, the side-mounted bed 1 includes a transverse tube group 15 formed by stacking and fixing multiple transverse tubes, and a reinforcing frame 16 disposed outside the transverse tube group 15; multiple first wiring openings 102 all penetrate the front and rear side walls of the transverse tube group 15; multiple second wiring openings 103 all penetrate the front and rear side walls of the transverse tube group 15. The transverse tube group 15 is formed by stacking multiple transverse tubes, and transverse tubes of different heights can be selected for stacking according to the height of the side-mounted bed 1. The preparation process is simple and can be completed without cutting large-format plates, which is conducive to reducing manufacturing costs. The setting of the reinforcing frame 16 is used to improve the structural rigidity of the side-mounted bed 1 on the one hand, and to provide wiring space for the direction of cables on the other hand, so as to make full and reasonable use of the spatial layout of the chassis.

[0038] See also Figure 2 In some embodiments, the reinforcement frame 16 is further provided with three third wiring openings 1611 extending in the left and right directions. The three third wiring openings 1611 correspond to the drag chains of the first chuck structure 31, the drag chains of the second chuck structure 32, and the drag chains of the third chuck structure 33, respectively, and are used to gather the lines of each drag chain to the outside of the side-mounted bed 1. The three drag chains are used to protect the cables of the three chuck structures to prevent the three chuck structures from pulling the cables during movement. The upper surface of the reinforcement frame 16 serves as a support surface for the three drag chains to support the movement of the three drag chains. In this way, the lines of most of the moving mechanisms on the pipe cutting equipment can be gathered by using the first wiring opening 102, the second wiring opening 103, and the third wiring opening 1611 on the side-mounted bed 1.

[0039] See also Figure 2In some embodiments, the reinforcement frame 16 includes a reinforcement upper cross beam 161, a reinforcement lower cross beam 162 disposed below the reinforcement upper cross beam 161, and a plurality of connecting vertical beams 163 for connecting the reinforcement upper cross beam 161 and the reinforcement lower cross beam 162; the bottom of the connecting vertical beam 163 is provided with a wiring notch 164 at a position close to the transverse tube group 15; the reinforcement upper cross beam 161, the reinforcement lower cross beam 162 and the connecting vertical beam 163 form a wiring cavity; the first wiring opening 102 and the second wiring opening 103 are disposed on the transverse tube group 15, and the third wiring opening 1611 is disposed on the reinforcement upper cross beam 161.

[0040] See also Figure 1In some embodiments, the side-mounted bed 1 is further provided with a first exhaust and dust removal port 101 that passes through the front and rear side walls thereof; a support 13 is further fixedly connected to the side wall of the side-mounted bed 1, and the lower surface of one end of the gantry 14 is fixedly connected to the upper surface of the support 13; the support 13 is a hollow structure, and the support 13 is provided with a second exhaust and dust removal port 131 that passes through the left and right side walls thereof, and the second exhaust and dust removal port 131 is connected to the first exhaust and dust removal port 101 through an exhaust and dust removal pipe (not shown in the figure); the air inlet of the second exhaust and dust removal port 131 is located in the cutting area, and the air outlet of the first exhaust and dust removal port 101 is connected to the exhaust equipment. By opening a second exhaust and dust removal port 131 on the support 13 below the gantry 14, the second exhaust and dust removal port 131 is closest to the laser cutting assembly 2. The exhaust and dust removal pipe cooperates with the exhaust equipment to directly suck the metal dust generated during the laser cutting process, effectively reducing the diffusion of dust in the workshop, improving the working environment, and protecting the health of operators. In addition, in this embodiment, the second exhaust and dust removal port 131 is used as an air inlet, and the first exhaust and dust removal port 101 is used as an air outlet. The exhaust equipment can be designed to be located behind the pipe cutting equipment, or lead out of the workshop through a pipeline, and only the exhaust pipeline is exposed, which plays a role in optimizing the dust removal path and improving the appearance of the equipment. Specifically, the exterior of the gantry 14 and the laser cutting assembly 2 will be surrounded by sheet metal parts to form a protective box, and the interior of the protective box is the cutting area. Therefore, the first exhaust and dust removal port 101 is set on the right side of the protective box, that is, the first exhaust and dust removal port 101 is led out of the outside of the protective box.

Specifically, multiple pipes are respectively limited in their respective feeding and storage bayonet, which can prevent the pipes from being displaced and ensure that the conveying speed of each pipe is consistent. The feeding rotation drive device 54 and the feeding transmission shaft 531 are used to realize the synchronous operation of multiple feeding and transporting chains 523, which has a simple structure and a high synchronization rate. In addition, the feeding driving wheel 521, the feeding driven wheel 522 and the feeding and transporting chain 523 are conventional chain transmission parts. The feeding limiting block 524 is assembled on the feeding and transporting chain 523 to form the feeding and storage bayonet, which has low manufacturing difficulty and low cost.

[0042] Specifically, the provision of the feed axis limiting plate 514 can prevent the pipe from easily sliding out / rolling out of the feed assembly 5 due to the inertia of the pipe moving forward. The feed axis limiting plate 514 is used to limit the movement of the pipe and improve safety.

[0043] See also Figure 3 In some embodiments, the feeding frame 51 includes a feeding crossbeam 511 parallel to the conveying direction of the pipe, a first feeding vertical beam 512 fixedly connected to the front of the feeding crossbeam 511, and a second feeding vertical beam 513 fixedly connected to the rear of the feeding crossbeam 511; the adjacent second feeding vertical beams 513 are connected by the feeding connecting rod 55.

[0044] See also Figure 4In some embodiments, the feeding driving wheel 521 is sleeved on the feeding rotating shaft 5211, and the feeding rotating shaft 5211 is connected to the feeding beam 511 through two feeding belt seat bearings 5212, and one end of the feeding rotating shaft 5211 is connected to the feeding transmission shaft 531 through a feeding universal joint coupling 532; the feeding rotation driving device 54 includes a feeding motor bracket 541, a feeding driving motor 542 arranged on the feeding motor bracket 541, a feeding driving sprocket 543 arranged on the output end of the feeding driving motor 542, a feeding driven sprocket 544 sleeved on one of the feeding rotating shafts 5211, and a feeding driving chain 545 wound between the feeding driving sprocket 543 and the feeding driven sprocket 544. When transporting pipes, the feeding drive motor 542 drives the feeding active sprocket 543 to rotate, and under the transmission of the feeding drive chain 545 and the feeding driven sprocket 544, the feeding shaft 5211 is driven to rotate, and then the feeding active wheel 521 on the feeding shaft 5211 is driven to rotate, providing power for the feeding transport chain 523.

[0045] See also Figure 1 In some embodiments, the plurality of material receiving components 7 each include a material receiving frame, a material receiving driving wheel rotatably arranged on the material receiving frame, a material receiving driven wheel, and a material receiving transport chain wound between the material receiving driving wheel and the material receiving driven wheel, a plurality of material receiving limiting blocks are arranged on the outer surface of the material receiving transport chain, and a material receiving storage bayonet is formed between two adjacent material receiving limiting blocks, the material receiving driving wheels on the plurality of material receiving components 7 are connected by a material receiving transmission shaft, and the material receiving transmission shaft is connected by a driving connection with a material receiving rotation driving device; please refer to Figure 1 and Figure 5 , a receiving axis limit plate 71 is provided at the rear end of the receiving rack, and the receiving axis limit plate 71 is used to prevent the pipe from being transported further to the rear. According to the above records, the structures of the receiving assembly 7 and the feeding assembly 5 are basically the same, and the main difference is that: according to the conveying inertia of the pipe, the receiving axis limit plate 71 is set downstream, and the feeding axis limit plate 514 is set upstream. In addition, the front end of the feeding rack 51 is fixedly connected to the mounting side seat 11, and the front end of the receiving rack is fixedly connected to the side wall of the side hanging bed 1. The feeding assembly 5 and the receiving assembly 7 adopt a basically similar structure, one is used for feeding, and the other is used for receiving, which can further simplify the complexity of the pipe cutting equipment and reduce the manufacturing cost.

In order to automatically detect whether the pipe is transported to the set position, the stroke sensing mechanism 72 is provided. When the pipe triggers the stroke sensing mechanism 72, it means that the pipe is transported to the position. At this time, the stroke sensing mechanism 72 feeds back a signal to the control system, and the control system controls the material receiving rotation driving device to stop working until the pipe is unloaded, and the material receiving rotation driving device restarts to realize the automatic material receiving and transportation of the next pipe. Specifically, when the pipe is conveyed to the position of the material receiving pressure plate 723, the material receiving pressure plate 723 is pressed down, triggering the travel switch 722, and the control system controls the material receiving rotating drive device to stop the conveyance of the pipe. After the pipe is unloaded and transferred to leave the material receiving frame, the material receiving rotating drive device will start again. The above-mentioned setting cooperates with the material receiving mechanism 6 to realize fully automatic material receiving and feeding.

[0047] See also Figure 6 In some embodiments, the plurality of receiving mechanisms 6 each include a base 61, a movable plate 62 movably disposed on the base 61, a lifting drive 63 for driving the movable plate 62 to rise or fall, a receiving plate 64 having one end surface rotatably connected to the upper portion of the movable plate 62, and a receiving drive 65 fixed to the movable plate 62 and used to drive the receiving plate 64 to tilt horizontally or downwardly. The lifting drive 63 drives the movable plate 62 to follow the pipe to rise and fall, thereby changing the height of the receiving plate 64 relative to the pipe (especially for non-circular pipes). When the pipe needs to be supported, the receiving drive 65 drives the receiving plate 64 to be in a horizontal state, and then the movable plate 62 and the receiving plate 64 move up and down; when the pipe needs to be unloaded, the receiving drive 65 drives the receiving plate 64 to be in an inclined state, thereby guiding the pipe placed on the receiving plate 64 to the front end of the receiving assembly 7.

[0048] See also Figure 7In some embodiments, the lifting drive member 63 includes a lifting drive motor 631, a transmission gear 632 connected to the output end of the lifting drive motor 631, and a transmission rack 633 arranged on the front side of the base 61; the output end of the lifting drive motor 631 passes through the front and rear side walls of the movable plate 62; the transmission rack 633 is vertically extended and arranged on the base 61; the transmission gear 632 is meshed with the transmission rack 633. When in use, when the lifting drive motor 631 rotates forward, it drives the transmission gear 632 to rotate forward, and under the guidance of the transmission rack 633, the movable plate 62 and the receiving plate 64 are synchronously raised. On the contrary, when the lifting drive motor 631 rotates reversely, it drives the transmission gear 632 to rotate reversely, so that the movable plate 62 and the receiving plate 64 are synchronously lowered. The above structure has high transmission efficiency and high transmission accuracy.

[0049] See also Figure 6 In some embodiments, the material receiving driving member 65 is a material receiving cylinder that is arranged obliquely.

When the sensing sheets 732 pass the position of the photoelectric sensor 731, the material receiving and transporting chain stops moving, and the material receiving mechanism will transfer the next pipe to the upstream of the material receiving and transporting chain only after the pipe at the downstream end of the material receiving and transporting chain is unloaded.

[0051] See also Figure 1 In some embodiments, a receiving box 66 is provided beside the receiving mechanism 6 near the laser cutting assembly 2, and the receiving box 66 is used to receive the tailings / short tubes. As shown in the figure, this position is in the cutting area, and the short tube receiving structure is used to support and receive the tailings / short tubes, so that the tailings / short tubes can be transferred to the receiving box 66 without being transported through the receiving assembly 7.
