Description

Technical Field

[0001] The invention specifically relates to the technical field of pipeline bending, and in particular to a combined processing device for a gas metal pipeline. Background Art

[0002] Gas generator pipelines are important channels that connect the gas supply source and the gas generator, and transport gas to the gas generator to achieve power generation. In general, the pipelines of gas generators are made of seamless steel pipes and stainless steel pipes. The pipeline direction should be reasonably planned according to factors such as the installation location of the gas generator, the gas supply source, and the surrounding environment. In order to reduce pressure loss and leakage risks, the use of elbows is generally reduced; therefore, the pipeline needs to be bent; and considering the installation location of the gas generator, the gas supply source, and the surrounding environment, a steel pipe needs to be bent continuously to meet the installation and use requirements of the pipeline under the premise of reducing the use of elbows.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 to 15 , in the embodiments of the present invention, a gas metal pipe combined processing device includes a speed reduction unit 1 capable of driving the rotary table 2 to rotate. The speed reduction unit 1 is composed of a servo motor and a speed reducer; a fixed seat 3 is fixed at the upper end of the rotary table 2, and an arc-shaped frame 4 is slidably connected inside the fixed seat 3; there is a gap in the middle of the arc-shaped frame 4, and a fixed block 11 is arranged in the gap. The fixed block 11 is convexly arranged, with its inner side fixedly connected to the rotary table 2 and its outer side extending to the outer edge of the arc-shaped frame 4; when the speed reduction unit 1 drives the rotary table 2 to rotate, the fixed seat 3 and the arc-shaped frame 4 will follow the rotation; above the fixed block 11, a profile frame 14 is fixed; the profile frame 14 is used to adjust the fixation of the cylinder 8; then the end of the adjustment cylinder 8 is connected to a bending part 7;

[0047] When the profile frame 14 rotates following the arc-shaped frame 4, the bending part 7 will also rotate. Since the bending die head 6 installed in cooperation with the inner side of the bending part 7 is welded with a fixed pipe 37 at its bottom, the fixed pipe 37 passes through the gap in the middle of the arc-shaped frame 4 and is fixedly connected to the upper surface of the machine box body 36; thus, when the bending part 7 rotates, the extrusion metal pipe is bent along the outer edge of the bending die head 6, thereby realizing the primary bending of the metal pipe.

[0048] If multiple bends at the same angle are required, the bent part of the metal pipe is pulled outwards, and then the above operations are performed at the position of the straight pipe, so as to realize multiple bends at the same angle; or the pipe is flipped 180 degrees to perform reverse bending in the same plane; it is possible to produce bent pipes in the shape of "冂" or "Z".

[0049] Furthermore, a semicircular gear ring 5 is fixed to the outer edge of the arc frame 4; the semicircular gear ring 5 is meshed and connected with the driving gear 13; the driving gear 13 is mounted on the output shaft of the driving motor 12; the driving motor 12 is fixed to the fixing block 11;

[0050] The outer side of the arc frame 4 is also provided with a convex shaft, through which a driving rod 15 is movably connected, and the other end of the driving rod 15 is movably connected to a deflection frame 16 equipped with a bending wheel 17; a top wheel 18 is installed under the bending wheel 17; one side of the chassis 36 is also provided with a cutting assembly 38 for cutting the metal pipe of the gas pipe.

[0051] Refer to the attached Fig. 9 When the metal tube needs to be bent in different planes, one end of the L-shaped metal tube is inserted between the bending wheel 17 and the top wheel 18; the driving motor 12 drives the driving gear 13 to rotate clockwise, and the semicircular gear ring 5 drives the arc frame 4 to rotate counterclockwise along the fixed seat 3. While rotating, the deflection frame 16 is driven to deflect through the driving rod 15. The bending wheel 17 installed in the deflection frame 16 presses the metal tube downward, and with the cooperation of the top wheel 18, the metal tube is bent. In this way, a pipeline with different plane bends can be obtained, which can be bent according to the installation requirements and space requirements of the gas engine.

[0052] Please refer to the attached Fig.11 In this embodiment, one end of the adjusting cylinder 8 away from the bending member 7 is fixed to the connecting plate 9, and the lower end of the connecting plate 9 is fixed to the cylinder rod of the secondary cylinder 10; the secondary cylinder 10 is fixed below the profile frame 14.

[0053] By adopting the above technical solution, when the cylinder rod of the adjusting cylinder 8 is extended, the bending part 7 can be pushed to move outward, so that the distance between the bending die head 6 and the bending part 7 is increased. On the one hand, metal pipes with different diameters can be bent; on the other hand, the bent metal pipe can be easily removed.

[0054] The secondary cylinder 10 is connected to the adjustment cylinder 8 via the connecting plate 9, thereby increasing the range of adjustment of the distance between the bending die head 6 and the bending part 7.

[0055] Please refer to the attached Fig. 9 In this embodiment, the deflection frame 16 is sleeved on the outer side of the top wheel 18 and deflects around the axis of the top wheel 18.

[0056] By adopting the above technical solution, when the deflection frame 16 is deflected, the axis of the top wheel 18 is taken as the center, so that the smooth bending process of the metal tube can be ensured.

[0057] Please refer to the attached Figure 7 and13 In this embodiment, the other end of the central axis for mounting the top wheel 18 is connected to the adjustment frame 19 through a bearing; two slide posts 21 are welded to the side where the adjustment frame 19 and the sliding frame 20 are in contact; the slide posts 21 are slidably connected in the sliding groove on the sliding frame 20, and a sliding plate 22 is provided between the two slide posts 21; the sliding plate 22 is arranged in a T-shape, passes through the sliding groove on the sliding frame 20 and is fixed to the adjustment frame 19; the upper end of the sliding plate 22 is fixed to the cylinder rod of the lifting cylinder 23, and the lifting cylinder 23 is fixed to the upper surface of the sliding frame 20.

[0058] By adopting the above technical solution, since some pipes need to have a certain tilt posture during processing, after the pipes are bent by the bending wheel 17 and the top wheel 18, the cylinder rod of the lifting cylinder 23 is extended, and the sliding plate 22 drives the sliding frame 20 to slide downward. At this time, the sliding column 21 slides downward along the sliding groove on the sliding frame 20 to ensure the stability of its movement; in this way, under the pull of the adjustment frame 19, the bending wheel 17 and the top wheel 18 clamp the pipe and tilt it downward, and finally the two bends of the processed pipe have a certain tilt effect; thereby meeting the space requirements of the gas engine during installation.

[0059] Please refer to the attached Fig.11 and 13 In this embodiment, one end of the sliding frame 20 is fixed between the rotating table 2 and the fixed seat 3 by bolts; the end of the sliding frame 20 close to the rotating table 2 is also penetrated by a U-shaped groove for the fixing pipe 37 to pass through.

[0060] By adopting the above technical solution, when the bending die 6 and the bending part 7 cooperate to bend the pipe, the sliding frame 20 needs to rotate as a whole. In order to prevent interference with the fixed pipe 37, a U-shaped groove is opened to ensure the coordinated movement of various components.

[0061] To be more specific, in this embodiment, the bending member 7 includes a fan-shaped member 71, which is hollow and has multiple auxiliary wheels 73 installed inside; the shafts at both ends of the auxiliary wheels 73 are slidably connected in the slide groove 72; there are multiple slide grooves 72, which are respectively opened on the top and bottom surfaces of the fan-shaped member 71; the fan-shaped member 71 is also fixedly connected to the U-shaped fixing head 74 by bolts; the U-shaped fixing head 74 is fixed to the cylinder rod end of the adjusting cylinder 8.

[0062] By adopting the above technical solution, the auxiliary wheel 73 can assist the smoothness of the pipe when bending. The auxiliary wheel 73 can not only bend the pipe, but also prevent the pipe from being broken due to hard contact with the outer surface of the pipe.

[0063] Please refer to the attached Fig.12In this embodiment, a clamping mechanism for pipe clamping is also included, the clamping mechanism has two mechanical grippers 34, the lower end of each mechanical gripper 34 is mounted on the cylinder rod of the lifting cylinder 33; the two lifting cylinders 33 are fixed on the sliding seat 32, the two sliding seats 32 are slidably connected to the transverse slide 28, and are fixed on both sides of the transverse slide 30;

[0064] A second motor 31 is fixed on the top of the transverse slide 30 ; the output shaft of the second motor 31 passes through the bottom of the transverse slide 30 and is matched with a gear meshing with the transverse rack 29 ; the transverse rack 29 is fixed on the inner side of the transverse slide 28 .

[0065] By adopting the above technical solution, the mechanical gripper 34 can clamp the pipe to ensure that unilateral warping does not occur when the bending wheel 17 and the top wheel 18 bend the pipe or tilt the pipe.

[0066] The second motor 31 drives the gear to rotate, and under the meshing of the gear and the transverse rack 29, the sliding seat 32 drives the lifting cylinder 33 and the mechanical clamp 34 to move laterally, so that the clamping position can be adjusted according to the extended length of the pipe.

[0067] Please refer to the attached Fig.12 In this embodiment, the transverse slide 28 is slidably connected to the longitudinal slide 24, and a longitudinal slide 25 is also fixed on one side of the transverse slide 28; a first motor 27 is fixed to the top of the longitudinal slide 25, and the output shaft of the first motor 27 passes through the bottom of the longitudinal slide 25, and is matched with a gear meshing with the longitudinal rack 26; the longitudinal rack 26 is fixed on the inner side of the longitudinal slide 24.

[0068] When the pipe is bent, especially after the bending die 6 and the bending member 7 perform a primary bending on the pipe, and a secondary bending is performed using the bending wheel 17 and the top wheel 18, the distance between the two bends needs to be adjusted according to the layout requirements of the site.

[0069] By adopting the above technical solution, after the bending die 6 and the bending part 7 bend the pipe once, we use the adjustment cylinder 8 and the secondary cylinder 10 to increase the distance between the bending die 6 and the bending part 7. At this time, the pipe can move freely between the bending die 6 and the bending part 7; that is to say, the position of the secondary bending can be adjusted at will; after adjusting to the appropriate position; the first motor 27 drives the gear to rotate, and after meshing and transmitting with the longitudinal rack 26, the longitudinal slide 25 and the transverse slide 28 will adjust their positions along the longitudinal slide 24 until the mechanical clamp 34 can clamp and fix the pipe after being bent by the bending die 6 and the bending part 7; in this way, after the mechanical clamp 34 clamps and fixes the pipe, it can ensure that the bending wheel 17 and the top wheel 18 perform secondary bending of the pipe or tilting of the pipe.

[0070] In this embodiment, the bottoms of both sides of the longitudinal slide 25 are also movably connected with balance wheels 35 via rotating shafts; the two balance wheels 35 are respectively located on both sides of the longitudinal slide 24 and are slidably connected to the longitudinal slide 24 .

[0071] By adopting the above technical solution, the balance wheel 35 slides along both sides of the longitudinal slide 24, which can ensure its stability during operation.

[0072] See also Fig.14 and Fig.15 In this embodiment, the cutting assembly 38 includes a saw blade 381, which is arranged in a saw blade groove 39 provided on the upper part of the chassis 36 and is mounted on the output shaft of a cutting motor 382; the cutting motor 382 is arranged outside the chassis 36, wherein the rotating shaft of the cutting motor 382 is slidably connected in a strip groove 387 provided on the outer side of the chassis 36; the cutting motor 382 is fixed to a motor bracket 383, and C-shaped slides 384 are fixed at both ends of the motor bracket 383, and the two C-shaped slides 384 are slidably connected to a slide column 385, and both ends of the slide column 385 are fixed to the outer side of the chassis 36 through fixed end blocks 386;

[0073] A driving bracket 388 is also fixed to the outside of the motor bracket 383, and the lower end of the driving bracket 388 is fixed to the cylinder rod of the lifting cylinder 389; the lower end of the lifting cylinder 389 is movably connected to the cylinder bracket 390 through a rotating shaft; the cylinder bracket 390 is fixed to the outside of the chassis 36.

[0074] By adopting the above technical solution, before or after bending, when the length of the pipe needs to be controlled, the cutting assembly 38 can be used to cut the pipe;

[0075] During cutting, the rod of the lifting cylinder 389 extends, driving the motor bracket 383 with the cutting motor 382 upward through the driving bracket 388. During the sliding process, the C-shaped carriage 384 slides along the sliding column 385 to ensure the linearity of the movement of the cutting motor 382. At this time, the saw blade 381 extends to the upper end of the saw blade slot 39, and the cutting motor 382 drives the saw blade 381 to operate, thereby realizing the cutting of the pipeline.

[0076] After cutting, the rod of the lifting cylinder 389 contracts, driving the motor bracket 383 with the cutting motor 382 downward through the driving bracket 388, so that the saw blade 381 contracts below the saw blade slot 39, thus avoiding interference during the bending process.

[0077] The working principle is as follows:

[0078] When in use, first insert the pipeline to be bent between the bending die head 6 and the bending part 7, and then adjust the rod of the cylinder 8 to contract, so that the bending die head 6 and the bending part 7 tightly fit the pipeline. When the speed reduction unit 1 drives the rotating table 2 to rotate, the fixed seat 3 and the arc-shaped frame 4 will rotate accordingly. When the profile frame 14 rotates with the arc-shaped frame 4, the bending part 7 will also rotate, and the bending of the pipeline is realized under the huge torque. If multiple bends at the same angle are required, pull out the bent part of the metal pipe outward, and then perform the above operations at the straight pipe position to achieve multiple bends at the same angle. Or turn the pipeline 180 degrees to perform reverse bending on the same plane. It can produce bent pipelines in the shape of "冂" or "Z".

[0079] When the metal pipe needs to be bent in different planes, insert one end of the metal pipe bent in an L shape between the bending wheel 17 and the top wheel 18. The driving motor 12 drives the driving gear 13 to rotate clockwise. At this time, the semi-circular tooth ring 5 drives the arc-shaped frame 4 to rotate counterclockwise along the fixed seat 3. During the rotation, the deflection frame 16 is driven to deflect through the driving rod 15. The bending wheel 17 installed in the deflection frame 16 presses the metal pipe downward, and with the cooperation of the top wheel 18, the bending of the metal pipe is realized, and a bent pipeline in different planes can be obtained, which can be bent according to the installation requirements and space requirements of the gas engine.

[0080] After the bending die 6 and the bending part 7 have bent the pipe once, we use the adjustment cylinder 8 and the secondary cylinder 10 to increase the distance between the bending die 6 and the bending part 7. At this time, the pipe can move freely between the bending die 6 and the bending part 7; that is, the position of the secondary bending can be adjusted at will; after adjusting to the appropriate position; the first motor 27 drives the gear to rotate, and after meshing and transmitting with the longitudinal rack 26, the longitudinal slide 25 and the transverse slide 28 will adjust their positions along the longitudinal slide 24 until the mechanical gripper 34 can clamp and fix the pipe after being bent by the bending die 6 and the bending part 7; in this way, after the mechanical gripper 34 clamps and fixes the pipe, it can ensure that the bending wheel 17 and the top wheel 18 can perform secondary bending or tilting of the pipe.

[0081] Before or after bending, when the length of the pipe needs to be controlled, the cutting assembly 38 can be used to cut the pipe;

[0082] When cutting, the cylinder rod of the lifting cylinder 389 extends out, and the motor bracket 383 equipped with the cutting motor 382 slides upward through the driving bracket 388. During the sliding process, the C-shaped slide 384 slides along the slide column 385, thereby ensuring the linearity of the movement of the cutting motor 382. At this time, the saw blade 381 reaches the upper end of the saw blade groove 39, and the saw blade 381 is driven by the cutting motor 382 to move, thereby realizing the cutting of the pipe.

[0083] After cutting is completed, the cylinder rod of the lifting cylinder 389 retracts, and drives the bracket 388 to slide downward with the motor bracket 383 equipped with the cutting motor 382, ​​so that the saw blade 381 retracts to the bottom of the saw blade groove 39, thereby avoiding interference in movement during the bending process.

[0084] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
