Detailed implementation mode

[0025] The present utility model provides an ultra-long three-chuck pipe cutting device. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the following further elaborates on the present utility model with reference to the attached drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the utility model.

[0026] Please refer to Figure 1 and Figure 2, the utility model provides an extra-long three-chuck pipe cutting device, which includes a side-hanging bed body 1 composed of a first sub-frame 11, a second sub-frame 12 and a third sub-frame 13 spliced together, a gantry 14 arranged on the second sub-frame 12, a laser cutting assembly 2 arranged on the gantry 14 and capable of moving along the X-axis and Z-axis, a first chuck structure 31, a second chuck structure 32 and a third chuck structure 33 slidably arranged on the side-hanging bed body 1 in sequence from back to front, a feeding mechanism 4 arranged upstream of the gantry 14, a plurality of receiving frames 5 arranged downstream of the gantry 14, and a plurality of finished product storage racks 6 arranged beside the receiving frames 5; the first sub-frame 11, the second sub-frame 12 and the third sub-frame 13 each include a horizontal pipe group 71 fixedly connected by stacking a plurality of horizontal pipes, and a reinforcing frame 72 arranged behind the horizontal pipe group 71. Installation cover plates 73 are arranged at both ends of the second sub-frame 12. Installation cover plates 73 are arranged at the connection ends of the first sub-frame 11 and the third sub-frame 13 with the second sub-frame 12. Decorative cover plates 74 are arranged at the non-connection ends of the first sub-frame 11 and the third sub-frame 13. The corresponding installation cover plates 73 of the first sub-frame 11 and the second sub-frame 12 are connected by bolts, and the corresponding installation cover plates 73 of the second sub-frame 12 and the third sub-frame 13 are connected by bolts; several installation side seats 15 are fixedly connected beside the first sub-frame 11 and the second sub-frame 12, and a centering support mechanism 9 is arranged on some of the installation side seats 15. The centering support mechanism 9 is used for centering and supporting the pipe 8.

[0027] In order to improve the splicing accuracy of the side-hanging bed body 1, the installation surface of the installation cover plate 73 is finely processed to improve the accuracy of splicing the first sub-frame 11, the second sub-frame 12 and the third sub-frame 13, and further ensure the straightness of the side-hanging bed body 1.

[0028] During actual processing, the pipe 8 is orderly transported to the upper part of the centering support mechanism 9 through the feeding mechanism 4, and then the centering support mechanism 9 centers and positions the pipe 8 and lifts the pipe 8 to be coaxial with the first chuck structure 31, the second chuck structure 32 and the third chuck structure 33. The pipe 8 will be clamped by the first chuck structure 31 and the second chuck structure 32, and the pipe 8 will be pushed by the first chuck structure 31 to move forward towards the laser cutting assembly 2 to realize cutting feed. If the pipe section to be cut is too long, it will be assisted by the third chuck structure 33 to improve the stability of pipe cutting. The cut pipe section is received by the receiving frame 5 and slides into the finished product storage rack 6 to realize blanking. It can be understood that the second chuck structure 32 can move relative to the laser cutting assembly 2. When there is remaining tail material of the pipe 8, the A-axis turntable controls the laser cutting head to be vertically downward, reduces the distance between the second chuck structure 32 and the laser cutting assembly 2, and then directly cuts the remaining pipe 8, thereby reducing the amount of tail material.

[0029] The side-hung bed body 1 has the advantages of being structurally compact and occupying a small space. In the present utility model, the side-hung bed body 1 of the three-jaw chuck pipe cutting equipment is designed to be composed of three sub-frames spliced together, so that the entire equipment can meet the processing requirements of ultra-long pipes 8 (for example, 12 meters long), thereby significantly expanding the processing range. The segmented design of the side-hung bed body 1 solves the size limitation problems encountered by the traditional integral side-hung bed body 1 during transportation and in the gantry milling machine, and the assembly is convenient and reliable. When long-distance transportation is required, especially for export, the side-hung bed body 1 can be disassembled into three sub-frames and easily loaded into a standard container, reducing the logistics cost and improving the transportation efficiency.

[0030] In this embodiment, as shown in Figure 3 and Figure 4 the feeding mechanism 4 includes a plurality of feeding modules 41 arranged side by side. Each feeding module 41 includes a frame 411 composed of a transverse frame body 4111 and a leg 4112 arranged at the rear end of the transverse frame body 4111, a driving sprocket 42 rotatably arranged on the transverse frame body 4111, a driven sprocket 43, and a transport chain 44 wound around the driving sprocket 42 and the driven sprocket 43. A plurality of material limiting blocks 45 are arranged on the outer side surface of the transport chain 44, and a material storage bayonet 46 is formed between two adjacent material limiting blocks 45. The driving sprockets 42 on two adjacent feeding modules 41 are drivingly connected through a synchronizing shaft 481, and the driving sprocket 42 on one of the feeding modules 41 is driven by a driving assembly 482. A connecting plate 47 is arranged at the bottom of the front end of the transverse frame body 4111, and the connecting plate 47 is installed on the top of the installation side seat 15 by screws. The front end of the transverse frame body 4111 is provided with a feeding station 40.

[0031] The front end of the transverse frame body 4111 is fixed to the top of the installation side seat 15 through the connecting plate 47 and fixing screws. In other words, the front end of the transverse frame body 4111 is supported by the installation side seat 15, and the rear end of the transverse frame body 4111 is supported by the leg 4112, so that the frame 411 is reliably fixed. During feeding, the pipe 8 is horizontally placed in the material storage bayonet 46 of the transport chain 44. Driven by the driving assembly 482, the transport chains 44 of all the feeding modules 41 move synchronously, jointly supporting the pipe 8 and driving the pipe forward. Whenever a pipe is transported to the feeding station 40, the transport chain 44 of the feeding module 41 stops moving and waits for the centering support mechanism 9 to lift the pipe so that the pipe 8 is separated from the feeding mechanism 4.

[0032] The legs 4112 of two adjacent feeding modules 41 are connected by a connecting rod 49, which strengthens the cooperation between various parts, making it a more unified and firm whole, and improving the anti-twisting ability and structural integrity. The driving assembly 482 specifically includes a driving motor and a transmission structure that is drivingly connected to one of the driving sprockets 42. The transmission structure can be a common transmission structure such as a synchronous belt transmission structure or a chain transmission structure.

[0033] The feeding module 41 only uses one leg 4112, which reduces the manufacturing cost and workload. However, the cross frame body 4111 is cleverly matched with the mounting side seat 15 on the side hanging bed body 1. The front end of the cross frame body 4111 is firmly fixed on the top of the mounting side seat 15, and the rear end is supported by the leg 4112, forming a stable support structure and ensuring the stability of the pipe 8 loading rack during operation.

[0034] In this embodiment, the feeding mechanism 4 is configured with six feeding modules 41 to cope with the transportation problem of ultra-long pipes 8. During actual feeding, two feeding modules 41 are used to cooperate in handling a 1500 mm long pipe 8, three feeding modules 41 are used to cooperate in handling a 3000 mm long pipe 8, four feeding modules 41 are used to cooperate in handling a 6000 mm long pipe 8, five feeding modules 41 are used to cooperate in handling a 9000 mm long pipe 8, and six feeding modules 41 are used to cooperate in handling a 12000 mm long pipe 8.

[0035] See Figure 5 and Figure 9 As shown, the receiving rack 5 includes a back rack 51, a first lifting slide plate 52 that slides up and down along the height direction of the back rack 51, a second lifting slide plate 53 that is vertically liftable on the first lifting slide plate 52, a receiving plate 54 hinged to one side of the top of the second lifting slide plate 53, a first lifting mechanism 56 for driving the first lifting slide plate 52 to rise or fall, a second lifting assembly 57 for driving the second lifting slide plate 53 to rise or fall following the first lifting slide plate 52. A turning drive cylinder 55 for driving the receiving plate 54 to swing along the hinge point is connected to the second lifting slide plate 53. The cylinder part of the turning drive cylinder 55 is hinged to the second lifting slide plate 53, and the output end of the turning drive cylinder 55 is hinged to the bottom surface of the receiving plate 54.

[0036] Install the backrest frame 51 on the side-hanging bed body 1. Drive the first lifting slide plate 52 to rise or fall through the first lifting mechanism 56. At the same time, make the second lifting slide plate 53 follow the first lifting slide plate 52 to rise or fall, so as to achieve a larger lifting stroke in a narrow space. Furthermore, it can drive the receiving plate 54 to rise, so that the receiving plate 54 supports the pipe 8 during the cutting of the pipe 8. After the pipe 8 is cut, it can drive the receiving plate 54 to fall, and drive the receiving plate 54 to swing and flip along the hinge point through the flipping driving cylinder 55, so that the pipe 8 tilts and falls onto the finished product storage rack 6 along the receiving plate 54, shortening the falling stroke of the pipe 8.

[0037] In order to facilitate driving the first lifting slide plate 52 to rise or fall, in this embodiment, the first lifting mechanism 56 includes a lifting driving motor 561 and a driving gear 562 connected to the output end of the lifting driving motor 561. The driving gear 562 is meshed and connected with a fixed rack 563. The fixed rack 563 is fixed on the backrest frame 51. The lifting driving motor 561 is fixed on the first lifting slide plate 52. The first lifting slide plate 52 is connected with a first slider 564. The backrest frame 51 is connected with a first vertical guide rail 565. The first slider 564 is slidably connected to the first vertical guide rail 565. The purpose is to drive the driving gear 562 to rotate through the lifting driving motor 561, so that the driving gear 562 climbs or descends along the fixed rack 563, and then drives the first lifting slide plate 52 to rise or fall. At the same time, make the first slider 564 slide along the first vertical guide rail 565 to improve the smoothness of the lifting movement of the first lifting slide plate 52.

[0038] In order to facilitate driving the second lifting slide plate 53 to follow the first lifting slide plate 52 to rise or fall, the second lifting assembly 57 includes a first positioning block 571 arranged on one side of the top of the backrest frame 51, a second positioning block 572 arranged on one side of the bottom of the second lifting slide plate 53, a rotating shaft 573 rotatably arranged above the first lifting slide plate 52, a follower sprocket 574 arranged on the rotating shaft 573, and a follower chain 575 with both ends respectively connected to the first positioning block 571 and the second positioning block 572. The follower chain 575 is meshed and connected with the follower sprocket 574. The purpose is that when the first lifting slide plate 52 rises, the follower sprocket 574 rises at the same time and pushes up the follower chain 575, so that the follower chain 575 pulls the second lifting slide plate 53 to rise at the same time. When the first lifting slide plate 52 descends, the follower sprocket 574 descends and retracts at the same time, so that the second lifting slide plate 53 descends according to gravity at the same time, so that the first lifting slide plate 52 and the second lifting slide plate 53 are linked to rise or linked to fall, realizing synchronous lifting of the two-stage structure and increasing the lifting stroke.

[0039] In order to facilitate improving the smoothness of the lifting movement of the second lifting slide plate 53, in this embodiment, a second slider 576 is connected to the side of the first lifting slide plate 52 away from the first slider 564, and the second lifting slide plate 53 is connected to a second vertically disposed guide rail 577. The second slider 576 is slidably connected to the second vertically disposed guide rail 577. The purpose is to make the second slider 576 slide along the second vertically disposed guide rail 577 while the second lifting slide plate 53 rises or falls, so as to improve the smoothness of the lifting movement of the second lifting slide plate 53.

[0040] In this embodiment, as shown Figure 5 in the figure, the finished product storage rack 6 includes a U-shaped bottom frame 61 and a buffer wooden square 62 arranged at the inner bottom of the U-shaped bottom frame 61. By providing the U-shaped bottom frame 61, it is possible to prevent the pipe 8 from deviating and falling out, and improve the yield rate of the pipe 8; by providing the buffer wooden square 62, the impact force of the pipe 8 during blanking can be reduced, ensuring the smooth blanking of the pipe 8 and preventing damage to the pipe 8.

[0041] Specifically, when the laser cutting assembly 2 cuts the pipe 8, during material receiving, the receiving plate 54 is driven by the flipping drive cylinder 55 to swing along the hinge point, so that the receiving plate 54 swings to a horizontal state to form a receiving plane parallel to the horizontal plane. The lifting drive motor 561 automatically drives the drive gear 562 to rotate under the control of the control system, so that the drive gear 562 rises or falls along the fixed rack 563, and then drives the first lifting slide plate 52 to rise or fall, dynamically adjusting the distance between the receiving plate 54 and the pipe 8. This not only enables the receiving plate 54 to avoid the rotation of the pipe section, but also enables the receiving plate 54 to abut against the bottom surface of the pipe section after the pipe 8 is cut to achieve material receiving. After receiving the pipe section, the drive gear is rotated by the lifting drive motor 561, so that the drive gear 562 descends along the fixed rack 563, and then drives the first lifting slide plate 52 to descend; when the first lifting slide plate 52 descends, the follower sprocket 574 also descends and retracts at the same time, so that the second lifting slide plate 53 descends simultaneously according to gravity, so that the first lifting slide plate 52 and the second lifting slide plate 53 are linked to descend, realizing the synchronous descent of the two-stage structure, increasing the descent stroke. While the second lifting slide plate 53 descends, the second slider 576 slides along the second vertically disposed guide rail 577 to improve the smoothness of the descending movement of the second lifting slide plate 53; the receiving plate 54 is driven by the flipping drive cylinder 55 to swing along the hinge point, so that the receiving plate 54 swings to an inclined state, enabling the pipe 8 to slide obliquely and fall onto the buffer wooden square 62.

[0042] In this embodiment, five receiving racks 5 are configured, one of which is located directly below the laser cutting assembly 2, and the remaining receiving racks 5 are arranged forward at intervals. When the length of the cut pipe section is ≤1m, only one receiving rack 5 is needed; when the length of the cut pipe section is ≥1m and ≤3m, two receiving racks 5 are used to receive it; when the length of the cut pipe section is ≥3m and ≤6m, three receiving racks 5 are used to receive it; when the length of the cut pipe section is ≥6m and ≤9m, four receiving racks 5 are used to receive it; when the length of the cut pipe section is ≥9m and ≤12m, five receiving racks 5 are used to receive it.

[0043] A hopper specially used for receiving short pipe sections is provided on the side of the receiving rack 5 located directly below the laser cutting assembly 2 .

[0044] In this embodiment, the loading mechanism 4 is equipped with six feeding modules 41 to cope with the transportation problem of extra-long pipes 8. During actual loading, a 1500 mm long pipe 8 is transported in coordination with two feeding modules 41, a 3000 mm long pipe 8 is transported in coordination with three feeding modules 41, a 6000 mm long pipe 8 is transported in coordination with four feeding modules 41, a 9000 mm long pipe 8 is transported in coordination with five feeding modules 41, and a 12000 mm long pipe 8 is transported in coordination with six feeding modules 41.

[0045] In this embodiment, the reinforcement frame 72 includes a reinforcement upper crossbeam, a reinforcement lower crossbeam arranged below the reinforcement upper crossbeam, and a plurality of connecting vertical beams connecting the reinforcement upper crossbeam and the reinforcement lower crossbeam. The reinforcement frame 72 helps to improve the structural strength of the side-mounted bed 1.

[0046] In the above, the transverse tubes, the reinforced upper transverse beams, the reinforced lower transverse beams, and the connecting vertical beams on the transverse tube group 71 are all made of rectangular steel tubes or square steel tubes, which have sufficient structural strength and rigidity. The components in the first subframe 11, the second subframe 12, and the third subframe 13 are all fixed by welding, and the overall structural strength is good. Therefore, the top surface of the reinforced upper transverse beam can be used as the support surface of the Y-axis drag chain, and the reinforced upper transverse beam supports the movement of the Y-axis drag chain.

[0047] In this embodiment, the laser cutting assembly 2 includes an X-axis slide slidably disposed on the gantry 14, an X-axis drive mechanism for driving the X-axis slide to move along the X-axis direction, a Z-axis slide slidably disposed on the X-axis slide, a Z-axis drive mechanism for driving the Z-axis slide to move along the Z-axis direction, and a laser cutting head disposed on the Z-axis slide. The laser cutting head combines the drive of the X-axis drive mechanism and the Z-axis drive mechanism and a variety of chuck clamping methods to complete the cutting of various pipes 8 and complex graphics.

[0048] Preferably, an outer enclosure 10 is provided around the gantry 14 and the laser cutting assembly 2. An electrical system can be arranged on the outer enclosure 10 to facilitate the air supply and power supply wiring for the laser cutting assembly 2 and the second chuck assembly, with reasonable wiring and aesthetics. The outer enclosure 10 can also block the outward emission of laser light to avoid damage to the surrounding staff.

[0049] It should be understood that the side-mounted bed body 1 is provided with a Y-axis guide rail and a Y-axis rack extending in the front-rear direction. The first chuck structure 31, the second chuck structure 32, and the third chuck structure 33 cooperate with the Y-axis guide rail and the Y-axis rack to achieve front-rear sliding. The specific structures and working principles of the centering support mechanism 9, the first chuck structure 31, the second chuck structure 32, and the third chuck structure 33 are prior arts and will not be elaborated here.
