Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and more specifically, to a lifting-type pipe feeding device. Background Technology

[0002] Existing laser tube cutting machines require a feeding device during processing to transport the tube to be processed to a follow-up support device, which lifts it and then clamps it with a rear chuck before transporting it to the laser head for cutting. Existing chain-type feeding devices place the tube on the V-shaped feeding groove of the chain and feed it by moving the chain.

[0003] However, due to the limited load-bearing capacity of the chain, this type of feeding device is only suitable for pipes with smaller weight and diameter. When conveying large-diameter, heavy pipes, the chain of this feeding device cannot bear the weight of the pipe and cannot meet the feeding requirements. Therefore, there is an urgent need for a new type of feeding device that can overcome the problem of insufficient chain load-bearing capacity. Utility Model Content

[0004] To address the shortcomings of existing systems, this utility model provides a lifting-type pipe feeding device. By optimizing the mechanical structure and drive method, it solves the problem of insufficient support for large-diameter pipes in existing chain-type feeding devices, thereby achieving efficient and stable automated feeding.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lifting-type pipe feeding device includes several parallel feeding frames. The bottom of each feeding frame is supported by multiple sets of legs. Several material support seats are evenly arranged on the right side wall of each feeding frame. A transmission mechanism is provided at the front end of each feeding frame. Two sets of front bearing seats and rear bearing seats are respectively installed at the front and rear parts of each feeding frame. A front sprocket shaft is rotatably mounted on the front bearing seat, and a rear sprocket shaft is rotatably mounted on the rear bearing seat. A front sprocket is installed at the left end of the front sprocket shaft, and a rear sprocket is installed at the left end of the rear sprocket shaft. The front sprocket and the rear sprocket are connected by a first chain. A driven sprocket is installed at the right end of the front sprocket shaft. The transmission mechanism is connected to the driven sprocket via a second chain.

[0007] Two sets of horizontal guide rails are installed side by side on the left side wall of the feeding rack. A lifting mechanism is provided on the left side of the feeding rack, and the lifting mechanism on each feeding rack is in a corresponding position. The lifting mechanism is slidably connected to the slide rail through several sliders, and the lifting mechanism is fixedly installed on the first chain.

[0008] Furthermore, the rear support legs of two adjacent sets of feeding racks are fixedly connected by a connecting rod.

[0009] Furthermore, the lifting mechanism includes a lifting frame, a feeding seat, and cylinders. The feeding seat is fixedly installed on the first chain, and the slider is installed on the rear side of the feeding seat. Two cylinders are installed at the bottom of the feeding seat, and the lifting frame is fixedly connected to the upper end of the piston rod of the two cylinders.

[0010] Furthermore, two buffer seats are installed on the feeding seat, and the two buffer seats are located on both sides of the cylinder respectively. The buffer seats are provided with guide sleeves inside, and guide shafts are installed inside the guide sleeves. The guide shafts are fixedly connected to the lifting frame.

[0011] Furthermore, the lifting frame is provided with a V-shaped groove, and a nylon pad with a corresponding shape is provided on the upper surface of the V-shaped groove.

[0012] Furthermore, a protective cover is installed on the feeding seat, and the protective cover is located in front of the two cylinders;

[0013] The left side of the feeding rack is equipped with a cable chain groove, and a cable chain is provided inside the cable chain groove. One end of the cable chain is fixedly connected to the feeding seat through a cable chain frame.

[0014] Furthermore, the transmission mechanism includes a transmission shaft, a drive sprocket, a worm gear reducer, a reducer shaft, and a motor. A worm gear reducer is installed at the front of several of the feeding racks. The worm gear reducer is fixedly mounted to the body of the pipe cutter via a reducer mount. The worm gear reducer is connected to the motor. A reducer shaft is mounted on the worm gear reducer. Several transmission shafts are provided at both ends of the reducer shaft. The reducer shaft is connected to adjacent transmission shafts via flanges, and adjacent transmission shafts are connected to each other via flanges. A drive sprocket is mounted on the transmission shaft at a position corresponding to the driven sprocket. The drive sprocket is connected to the driven sprocket via a second chain. The transmission shaft also has several fixed bearing seats, which are fixedly mounted to the body of the pipe cutter.

[0015] Furthermore, the material support base is provided with an asymmetrical V-shaped material support groove, and a nylon pad with a corresponding shape is installed on the inner wall of the material support groove.

[0016] Furthermore, a shaft hole is provided at the rear end of the feeding frame. The shaft hole is elongated. The rear sprocket shaft is installed in the bearing hole. Tension adjustment seats are provided on both sides of the rear of the feeding frame. The rear bearing seat is installed on the tension adjustment seat. Adjustment holes are provided at the four corners of the tension adjustment seat. The adjustment holes are elongated. Threaded holes corresponding to the adjustment holes are provided on the side wall of the rear of the feeding frame. The tension adjustment seat is installed on the threaded holes of the feeding frame by bolts.

[0017] Furthermore, a support frame is provided on the right side of the rightmost feeding rack, and a positioning baffle is vertically installed on the right side of the support frame. The longitudinal length of the positioning baffle is greater than the total length of the plurality of material support seats.

[0018] In practical use, the large-diameter pipe to be processed is placed on the support base. The motor drives the first chain to rotate, causing the feeding base to move along the guide rail to the position of the nearest pipe. Then, the piston rod of the cylinder extends, causing the lifting frame to rise and lift the pipe, thus detaching it from the support base. The motor then drives the first chain to rotate in the opposite direction, causing the feeding base to lift the pipe and move it to the front position of the feeding frame. A follow-up support device is installed on the pipe cutting machine at the position corresponding to the feeding base. The follow-up support device lifts the pipe held by the feeding base and, after being clamped by the chuck, transports it to the laser head position for cutting. After the pipe cutting machine completes the cutting of the first pipe, the first chain drives the feeding base to move to the position of the second pipe, and the above operation is repeated to realize the feeding of pipes.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Improved load-bearing capacity: The feeding seat is driven by a chain, and the feeding seat is driven by a cylinder to lift the pipe and move along the guide rail. The weight of the pipe is distributed between the feeding seat and the guide rail, which can overcome the problem of insufficient support for large-diameter pipes when the chain directly bears the weight in the existing technology. It is suitable for large-diameter and heavy pipes.

[0021] 2. Strong positioning and stability: The asymmetrical V-shaped support seat provides good constraint on the position of the pipe, and the guide shaft ensures that the lifting frame is raised and lowered synchronously, avoiding deviation.

[0022] 3. High structural reliability: The tension adjustment device can adjust the chain tension in real time, the connecting rod connection improves the overall rigidity, and the nylon plate reduces wear and extends the service life of the device.

[0023] 4. High degree of automation: The motor drive, combined with the guide rail movement, realizes full automation of the pipe feeding process, improving production efficiency. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0036] Example:

[0037] like Figures 1 to 10As shown, a lifting-type pipe feeding device includes several parallel feeding racks 2. The bottom of the feeding racks 2 is supported by multiple sets of support legs 9. Several material support seats 10 are evenly arranged on the right side wall of the feeding racks 2 for supporting pipes. A transmission mechanism 5 is provided at the front end of the feeding racks 2. Two sets of front bearing seats 21 and rear bearing seats 16 are respectively installed at the front and rear parts of the feeding racks 2. A front sprocket shaft 22 is rotatably installed on the front bearing seat 21, and a rear sprocket shaft 14 is rotatably installed on the rear bearing seat 16. A front sprocket 23 is installed at the left end of the front sprocket shaft 22, and a rear sprocket 17 is installed at the left end of the rear sprocket shaft 14. The front sprocket 23 and the rear sprocket 17 are connected by a first chain 12. A driven sprocket 20 is installed at the right end of the front sprocket shaft 22. The transmission mechanism 5 is connected to the driven sprocket 20 through a second chain 19.

[0038] Two sets of horizontal guide rails 11 are installed side by side on the left side wall of the feeding rack 2. A lifting mechanism 6 is provided on the left side of the feeding rack 2, and the lifting mechanism 6 on each feeding rack 2 is in a corresponding position. The lifting mechanism 6 is slidably connected to the guide rail through several sliders 18, and the lifting mechanism 6 is fixedly installed on the first chain 12. When the first chain 12 rotates, it can drive the feeding seat 63 to move horizontally along the guide rail 11.

[0039] In this embodiment, the rear support legs 9 of two adjacent sets of feeding racks 2 are fixedly connected by a connecting rod 1, which can improve the integrity of the feeding device. When the feeding rack 2 is lifting the pipe, it may be subjected to lateral forces such as pipe eccentricity and inertial impact. The connecting rod 1 forms an integral frame with the adjacent support legs 9 through rigid connection, reducing lateral deformation and ensuring overall rigidity.

[0040] In this embodiment, the lifting mechanism 6 includes a lifting frame 61, a feeding seat 63, and a cylinder 66. The feeding seat 63 is fixedly installed on the first chain 12, and the slider 18 is installed on the rear side of the feeding seat 63. Two cylinders 66 are installed at the bottom of the feeding seat 63. The lifting frame 61 is fixedly connected to the upper end of the piston rod of the two cylinders 66. The lifting frame 61 is driven to rise and fall by the contraction of the piston rod on the cylinder 66 to lift the pipe.

[0041] In this embodiment, two buffer seats 64 are installed on the feeding seat 63. The two buffer seats 64 are located on both sides of the cylinder 66. The buffer seats 64 can absorb the impact energy when the lifting frame 61 is raised and lowered, reducing vibration and noise. The buffer seat 64 is provided with a guide sleeve, and a guide shaft 65 is installed in the guide sleeve. The guide shaft 65 is fixedly connected to the lifting frame 61. The guide shaft 65 keeps the lifting frame 61 stable during raising and lowering, restricts the lifting frame 61 to move only in the vertical direction, and avoids the lifting frame 61 from deviating during raising and lowering.

[0042] In this embodiment, the lifting frame 61 is provided with a V-shaped groove 67 for positioning the pipe during lifting, and a nylon pad 102 with a corresponding shape is provided on the upper surface of the V-shaped groove 67. The nylon pad 102 can prevent the pipe surface from directly contacting the lifting frame 61, thereby reducing the wear of the pipe outer wall by the lifting frame 61.

[0043] In this embodiment, a protective cover 62 is installed on the feeding seat 63. The protective cover 62 is located in front of the two cylinders 66 and can protect the cylinders 66.

[0044] A cable chain 7 slot is installed on the left side of the feeding rack 2. The cable chain 7 is installed inside the cable chain 7 slot. One end of the cable chain 7 is fixedly connected to the feeding seat 63 through the cable chain 7 frame. The cable chain 7 is used to install related pipelines, such as the pipeline of the drive cylinder 66. The cable chain 7 is placed in the cable chain 7 slot, which plays a role in storing the cable chain 7 and making it easy for the cable chain 7 to move together with the feeding rack 2.

[0045] In this embodiment, the transmission mechanism 5 includes a transmission shaft 51, a drive sprocket 53, a worm gear reducer 55, a reducer shaft 56, and a motor 57. A worm gear reducer 55 is provided at the front of several feeding racks 2. The worm gear reducer 55 is fixedly installed on the body of the pipe cutter through a reducer base. The worm gear reducer 55 is connected to the motor 57. A reducer shaft 56 is mounted on the worm gear reducer 55. Several transmission shafts 51 are provided at both ends of the reducer shaft 56. The reducer shaft 56 is connected to the adjacent transmission shaft 51 through a flange 54. Adjacent transmission shafts 51 are connected to each other through flanges 54, enabling multiple transmission shafts 51 to rotate synchronously. A drive sprocket 53 is mounted on the transmission shaft 51 at a position corresponding to the driven sprocket 20. The drive sprocket 53 is connected to the driven sprocket 20 through a second chain 19. The transmission shaft 51 is also provided with several fixed bearing seats 52. The fixed bearing seats 52 are fixedly installed on the body of the pipe cutter to support the transmission shaft 51. The motor 57 drives the reducer shaft 56 on the worm gear reducer 55 to rotate, which in turn drives the transmission shaft 51 to rotate, and further drives the drive sprocket 53, the second chain 19, and the driven sprocket 20 to rotate. The driven sprocket 20 drives the front sprocket 23, the first chain 12, and the rear sprocket 17 to rotate, which in turn drives the lifting mechanism 6 on the first chain 12 to move.

[0046] In this embodiment, the material support 10 has an asymmetrical V-shaped material support groove 101 for placing the pipe to be processed and for supporting and positioning the pipe. When the pipe is placed in the material support groove 101, the centerline of the pipe and the centerline of the V-shaped material support groove 101 are not on the same straight line. The long side of the material support groove 101 plays a role in bearing the weight of the pipe, while the short side plays a role in providing auxiliary support for the pipe. Compared with the symmetrical V-shaped structure, the asymmetrical V-shaped material support groove 101 of the material support 10 has better constraint on the position of the pipe. A nylon pad 102 with a corresponding shape is installed on the inner wall of the material support groove 101 to avoid direct contact between the surface of the pipe and the inner wall of the material support groove 101, thereby reducing the wear of the outer wall of the pipe by the material support 10.

[0047] In this embodiment, a shaft hole 13 is provided at the rear end of the feeding rack 2. The shaft hole 13 is elongated. The rear sprocket shaft 14 is installed in the bearing hole and can be adjusted horizontally along the shaft hole 13. Tension adjustment seats 15 are provided on both sides of the rear of the feeding rack 2. The rear bearing seat 16 is installed on the tension adjustment seat 15. Adjustment holes 151 are provided at the four corners of the tension adjustment seat 15. The adjustment holes 151 are elongated. Threaded holes corresponding to the adjustment holes 151 are provided on the side wall of the rear of the feeding rack 2. The tension adjustment seat 15 is installed on the threaded holes of the feeding rack 2 by bolts.

[0048] When the tension of the first chain 12 needs to be adjusted, the bolt can be turned to make the tension adjustment seat 15 move east and west. Then, the tension adjustment seat 15 can be adjusted horizontally along the adjustment hole 151. When the tension adjustment seat 15 moves, it can drive the rear sprocket 17 to move, thereby adjusting the distance between the rear sprocket 17 and the front sprocket 23, which plays the role of adjusting the tension of the first chain 12.

[0049] In this embodiment, a support frame 3 is provided on the right side of the rightmost feeding rack 2, and a positioning baffle 4 is vertically installed on the right side of the support frame 3. The longitudinal length of the positioning baffle 4 is greater than the total length of the plurality of material support seats 10. The positioning baffle 4 can restrict the end position of the pipe, maintain the consistency of the pipe, and prevent the pipe from slipping off the end position.

[0050] The working principle of this lifting-type pipe feeding device:

[0051] In actual use, the large-diameter pipe to be processed is placed on the support seat 10. The motor 57 drives the first chain 12 to rotate, causing the feeding seat 63 to move along the guide rail 11 to the position of the nearest pipe. Then, the piston rod of the cylinder 66 extends, causing the lifting frame 61 to rise and lift the pipe, thus separating it from the support seat 10. Then, the motor 57 drives the first chain 12 to rotate in the opposite direction, causing the feeding seat 63 to lift the pipe and move it to the frontmost position of the feeding frame 2. A follow-up support device is set at the position corresponding to the feeding seat 63 on the pipe cutting machine. The follow-up support device lifts the pipe held by the feeding seat 63 and is clamped by the chuck and transported to the position of the laser head for cutting. After the pipe cutting machine completes the cutting of the first pipe, the first chain 12 drives the feeding seat 63 to move to the position of the second pipe, and the above operation is repeated to realize the feeding of pipes.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
