DETAILED DESCRIPTION

[0027] The present invention provides a three-chuck bevel pipe cutting device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2The present invention provides a three-chuck groove pipe cutting equipment, including a side-hanging bed 1 composed of a first sub-frame 111 and a second sub-frame 112, a gantry 13 arranged on the second sub-frame 112, a laser cutting component 3 arranged on the gantry 13 and capable of displacement along the x-axis, the z-axis and the A-axis, a first chuck structure 71, a second chuck structure 72 and a third chuck structure 73 slidably arranged on the side-hanging bed 1 from back to front in sequence, a loading mechanism 8 arranged on the side of the first sub-frame 111, and a material receiving mechanism 9 arranged on the side of the second sub-frame 112; a plurality of mounting side seats 16 are fixedly connected to one side of the first sub-frame 111, and a centering support mechanism 5 is provided on some of the mounting side seats 16, and the centering support mechanism 5 is used for centering and supporting the pipe.

[0029] In actual application, the pipe is transported to the top of the centering support mechanism 5 in an orderly manner through the feeding mechanism 8, and then the centering support mechanism 5 centers the pipe and lifts the pipe to be coaxial with the first chuck structure 71, the second chuck structure 72 and the third chuck structure 73. The pipe will be clamped by the first chuck structure 71 and the second chuck structure 72 and pushed forward by the first chuck structure 71 toward the laser cutting assembly 3 to achieve cutting and feeding. The cut pipe section will be clamped by the third chuck structure 73 for unloading. Since the laser cutting assembly 3 can move in multiple axes, it can not only perform straight cutting on the pipe, but also perform bevel cutting on the pipe. The cut pipe section is received by the receiving mechanism 9 and slides into the finished product storage rack 90 for unloading. It can be understood that the second chuck structure 72 can move relative to the laser cutting assembly 3. When there is residual material of the tube, the A-axis turntable 38 controls the laser cutting head 39 to face vertically downward, reducing the distance between the second chuck structure 72 and the laser cutting assembly 3, and then directly cutting the remaining tube, thereby reducing the amount of residual material.

[0030] In actual application, two three-chuck beveling pipe cutting machines are arranged in a mirror-symmetrical manner. The mirror-symmetrical arrangement allows the machines to be arranged closely together, which can significantly reduce the floor space of the production line, especially in space-constrained plants. This layout can make more effective use of available space. The operator can monitor and control the two machines without much movement, which simplifies the operation process, reduces the operator's physical exertion, and improves work efficiency.

[0031] For details, see Figure 1 and Figure 8As shown, the feeding mechanism 8 includes two feeding components 81 and a supporting component 82 arranged between the two feeding components 81, the feeding component 81 includes a first frame 811, a first sprocket 812 and a second sprocket 813 rotatably arranged on the frame, and a transport chain 814 wound around the first sprocket 812 and the second sprocket 813, a plurality of limiting blocks 815 are provided on the outer surface of the transport chain 814, and a storage bayonet 816 is formed between two adjacent limiting blocks 815, the first sprockets 812 on the two feeding components 81 are connected by a transmission shaft 83, and the transmission shaft 83 is connected by a rotation drive device 84; the supporting component 82 includes a second frame 821 and an optical axis 822 fixed on the second frame 821, and the optical axis 822 extends along the transport direction; one of the legs of the first frame 811 and the second frame 821 is fixedly connected to the corresponding mounting side seat 16, and the other leg of the first frame 811 and the second frame 821 is placed on the ground.

[0032] In other words, the first rack 811 and the second rack 821 are " "-shaped structure, that is, one leg of the first frame 811 on the feeding assembly 81 is shorter and fixed to the mounting side seat 16 by screws, and the other leg is in contact with the ground through the height adjustment foot cup, one leg of the second frame 821 is shorter and fixed to the mounting side seat 16 by screws, and the other leg of the second frame 821 is in contact with the ground through the height adjustment foot cup. Similarly, the rotation drive device 84 is also fixed to the mounting side seat 16. It can be understood that the transport chain 814 is provided with a discharge station at a position close to the second sprocket 813, and the transport chain 814 is provided with a loading station at a position close to the first sprocket 812, and the pipes placed on the discharge station move toward the loading station with the movement of the transport chain 814.

[0033] When loading, place the pipe horizontally and extend it laterally. After the pipe is placed at the unloading station, the two ends of the pipe are clamped in the material storage openings 816 of the two transport chains 814. Driven by the rotating drive device 84, the transport chains 814 of the two feeding components 81 move synchronously to drive the pipe forward. At the same time, the middle of the pipe is supported by the optical axis 822 to prevent the middle of the pipe from bending and sagging. Since the surface of the optical axis 822 is chrome-plated, the surface is smooth and the hardness is high. The friction between the pipe and the optical axis 822 is small and will not cause damage to the pipe. Whenever a pipe is transported to the loading station, the transport chains 814 of the two feeding components 81 stop moving and wait for the centering support mechanism to lift the pipe so that the pipe is separated from the loading rack.

[0034] The three-chuck bevel pipe cutting equipment provided by the present invention, on the one hand, designs the bed as a side-mounted bed 1 composed of a first sub-frame 111 and a second sub-frame 112, and on the other hand, the loading mechanism 8 is simplified in design, and the connection and fixation are achieved by installing a side seat 16, so that the overall width is reduced. Even in a factory building with limited area, the space can be effectively utilized, which is conducive to the arrangement of multiple equipment, thereby improving the flexibility of the production layout.

[0035] In order to adjust the tightness of the transport chain 814, the second sprocket 813 is arranged on the adjustment support shaft 817 through a bearing, and the circumferential wall at both ends of the adjustment support shaft 817 is provided with a stop plane, and the stop plane is provided with a tightening threaded hole. The first frame 811 is provided with two fixing blocks 818, and each fixing block 818 passes through a tightening screw 819 that matches the tightening threaded hole, and the head of the tightening screw 819 presses on the fixing block 818 and the screw part of the tightening screw 819 is connected to the tightening threaded hole; by twisting the head of the tightening screw 819, the front and rear position of the adjustment support shaft 817 can be fine-tuned, so that the transport chain 814 can obtain a suitable tension. In order to prevent the tightening screw 819 from loosening due to resonance during long-term operation, the tightening screw 819 is equipped with two locking nuts, one of which presses on the stop plane of the adjustment support shaft 817, and the other locking nut and the head of the tightening screw 819 clamp the fixing block 818 together.

[0036] Preferably, see Figure 8 As shown, the first sprocket 812 is sleeved on the rotating shaft 810, and the rotating shaft 810 is connected to the first frame 811 through two seat bearings, and one end of the rotating shaft 810 is connected to the transmission shaft 83 through the universal joint coupling 8101. In other words, when one of the rotating shafts 810 rotates, the power is transmitted to the other rotating shaft 810 through the universal joint coupling 8101, the transmission shaft 83 and the universal joint coupling 8101 in sequence. The universal joint coupling 8101 can compensate for the misalignment problem caused by a certain angle deviation or displacement between the axes of the two rotating shafts 810, so that the two rotating shafts 810 can maintain mutual connection and transmit torque, reducing the strict requirements for axis pairing.

[0037] Preferably, the rotation drive device 84 is specifically a feeding drive motor that drives the rotating shaft 810 to rotate through a synchronous belt transmission structure or a chain transmission structure, and then drives the first sprocket 812 on the rotating shaft 810 to rotate, providing power for the transport chain 814.

[0038] In order to prevent the transport chain 814 from failing to control after the pipe is transported to the loading station, causing the transport chain 814 to continue to drive the pipe to move forward, thereby causing the pipe to fall from the transport chain 814 to the ground and be damaged, a baffle plate 85 is provided on the side of the first frame 811 for preventing the pipe from continuing to be transported forward, and a loading station is provided upstream of the baffle plate 85 and a stroke sensing mechanism 86 for sensing the pipe.

[0039] Specifically, the travel sensing mechanism 86 includes a support plate fixed on the first frame 811, a travel switch arranged on the support plate, and a pressure plate arranged on the output end of the travel switch. When the transport chain 814 drives the pipe to approach the loading station, the pipe slides into the center of the pressure plate. The weight of the pipe causes the pressure plate to flip, thereby triggering the travel switch, which feeds back to the control system. The control system controls the rotation drive device 84 to stop working, thereby causing the pipe to just move to the loading station.

[0040] In this embodiment, see Figure 6 and Figure 7 As shown, the first sub-frame 111 and the second sub-frame 112 both include a transverse tube group 14 formed by stacking and fixing multiple transverse tubes, and a reinforcing frame 15 arranged behind the transverse tube group 14. Through such an arrangement, the bed is lightweight in design, adapts to a fast manufacturing rhythm, and has good structural stability.

[0041] For details, see Figure 6 and Figure 7 As shown, the connecting end of the first subframe 111 and the second subframe 112 is provided with a mounting plate 123, and the non-connecting end of the first subframe 111 and the second subframe 112 is provided with a decorative plate 124, and the mounting plates 123 corresponding to the first subframe 111 and the second subframe 112 are connected by bolts. The mounting surface of the mounting plate 123 is finely processed to improve the accuracy of the splicing of the first subframe 111 and the second subframe 112, thereby ensuring the straightness of the side-mounted bed 1.

[0042] For further information, see Figure 6 and Figure 7 As shown, the reinforcement frame 15 includes a reinforced upper cross beam 151, a reinforced lower cross beam 152 arranged below the reinforced upper cross beam 151, and a plurality of connecting vertical beams 153 connecting the reinforced upper cross beam 151 and the reinforced lower cross beam 152. The reinforced upper cross beam 151 and the reinforced lower cross beam 152 and the connecting vertical beams 153 together form a more stable frame structure, which significantly enhances the rigidity and deformation resistance of the entire side-mounted bed 1.

[0043] The top surface of the reinforced upper crossbeam 151 can be used as the support surface of the Y-axis drag chain, and the reinforced upper crossbeam 151 supports the movement of the Y-axis drag chain. The bottom of the connecting vertical beam 153 is provided with a wiring notch 154 near the horizontal tube group 14. The wiring notch 154 design provides a convenient wiring channel, standardizes the line direction, is beautiful and improves safety, and also simplifies the maintenance and repair process.

[0044] In the above, the transverse tubes on the transverse tube group 14, the reinforced upper transverse beam 151, the reinforced lower transverse beam 152, and the connecting vertical beam 153 are all made of rectangular steel tubes or square steel tubes, which have sufficient structural strength and rigidity. The various components in the first subframe 111 and the second subframe 112 are fixed by welding, and the overall structural strength is good.

[0045] In this embodiment, the transverse tube group 14 of the second sub-frame 112 is provided with an exhaust dust removal port 121 near the laser cutting assembly 3. The exhaust dust removal port 121 is provided with an inner sealing plate 122 that is separated from the interior of the transverse tube. The inner sealing plate 122 ensures that the exhaust airflow is concentrated on the exhaust dust removal port 121, and avoids the exhaust airflow entering the interior of the transverse tube to cause airflow dispersion, thereby enhancing the efficiency of the exhaust system and more efficiently extracting the dust generated during the cutting process. In fact, the exhaust dust removal port 121 works with the exhaust dust removal mechanism, so that the exhaust dust removal port 121 has a negative pressure exhaust capability. During the cutting process, when the exhaust dust removal mechanism is started, the airflow in the cutting area is sucked into the exhaust dust removal port 121 by negative pressure, thereby sucking the metal dust generated during the laser cutting process, effectively reducing the spread of dust in the workshop, improving the working environment, and protecting the health of operators.

[0046] See Figure 1 As shown, a first Y-axis guide rail 21 and a Y-axis rack 22 are provided on the top surface of the side-mounted bed 1 , and a second Y-axis guide rail 23 is provided on a side surface of the side-mounted bed 1 .

[0047] The first chuck structure 71 includes a first side hanging plate 711, a first chuck body 712 disposed on the first side hanging plate 711, and a first Y-axis driving motor 713, the output end of the first Y-axis driving motor 713 is provided with a first Y-axis gear meshing with the Y-axis rack 22, and the first side hanging plate 711 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through a Y-axis slider. Similarly, the second chuck structure 72 includes a second side hanging plate 721, a second chuck body 722 disposed on the second side hanging plate 721, and a second Y-axis driving motor 723, the output end of the second Y-axis driving motor 723 is provided with a second Y-axis gear meshing with the Y-axis rack 22, and the second side hanging plate 721 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through a Y-axis slider. Similarly, the third chuck structure 73 includes a third side hanging plate 731, a third chuck body 732 arranged on the third side hanging plate 731, and a third Y-axis drive motor 733. The output end of the third Y-axis drive motor 733 is provided with a second Y-axis gear meshing with the Y-axis rack 22. The third side hanging plate 731 is slidably connected to the first Y-axis guide rail 21 and the second Y-axis guide rail 23 through a Y-axis slider.

[0048] Specifically, the laser cutting assembly 3 includes an X-axis slide 31 slidably disposed on the gantry 13, an X-axis drive mechanism for driving the X-axis slide 31 to move along the X-axis direction, a Z-axis slide 35 slidably disposed on the X-axis slide 31, a Z-axis drive mechanism for driving the Z-axis slide 35 to move along the Z-axis direction, an A-axis turntable 38 disposed at the lower end of the Z-axis slide 35, and a laser cutting head 39 mounted on the A-axis turntable 38. Under the control of the A-axis turntable 38, the laser cutting head 39 rotates within a range of ±45° to achieve a change in the cutting angle, so that the laser cutting head 39 can not only perform straight cutting processing on the pipe but also perform groove cutting on the pipe, and the combination of the drive of the X-axis drive mechanism and the Z-axis drive mechanism realizes precise positioning and cutting of the laser cutting head 39 in three-dimensional space.

[0049] See Figure 2 and Fig. 9 As shown, the centering support mechanism 5 includes a fixed vertical plate 51 fixed on the mounting side seat 16, a lifting slide plate 52 movably arranged on the fixed vertical plate 51, a lifting drive mechanism 55 for driving the lifting slide plate 52 to move up and down, and a clamping positioning mechanism 56 arranged on the lifting slide plate 52, the clamping positioning mechanism 56 is used to clamp the pipe to a set position to achieve positioning, and two supports 53 are provided on the top of the lifting slide plate 52, and the two supports 53 jointly support a laterally extending and rotatable support roller 54.

[0050] After the feeding mechanism 8 automatically transports the pipe to the support roller 54, the support roller 54 supports the pipe, and the clamping positioning mechanism 56 first clamps the pipe to the middle of the support roller 54, and then the lifting drive mechanism 55 lifts the pipe to a set height, so that the pipe is coaxial with the first chuck structure 71, the second chuck structure 72 and the third chuck structure 73, so that the first chuck structure 71 and the second chuck structure 72 can clamp the pipe. During the processing, the support roller 54 supports the pipe fittings. When the pipe is about to rotate or interferes with the movement of the first chuck structure 71, the lifting drive mechanism 55 controls the components on the lifting slide 52 to descend to avoid it.
