Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment, and in particular to a follow-up support structure and a pipe cutting machine. Background Technology

[0002] Pipe cutting machines are widely used in the cutting and processing of metal pipes. For pipes that are long or heavy, sagging and swaying are prone to occur during feeding, rotation, and cutting. Therefore, a follow-up support structure is usually required to support the pipe and ensure the stability and cutting accuracy during the pipe processing.

[0003] Existing follow-up support structures generally include a support mechanism and a clamping mechanism. To support and clamp pipes of different specifications, the support and clamping mechanisms are usually installed on separate mounting frames or platforms, occupying a large space and involving numerous components. Some follow-up support structures combine the support and clamping mechanisms, but this results in numerous connecting structures, with support rollers and clamping components mounted at different heights or on different support frames. When the pipe is subjected to clamping and support forces, the load transmission path is long, easily leading to structural deformation or vibration, thus affecting the pipe support effect and processing accuracy. These problems are particularly pronounced during the processing of long, heavy pipes. Summary of the Invention

The push plate is connected to the side of the two second fixed blocks away from the second slider. The fixed end of the cylinder is mounted on the second fixed plate, and the movable end of the cylinder is drivenly connected to the push plate. The cylinder drives the push plate to move vertically, and the two clamping members move closer or further apart through the two connecting rods.

[0007] As a further improvement to the above technical solution, the clamping mechanism also includes a pin, the push plate is provided with a notch, the two connecting rods are hinged to the second slider through the pin, and the notch corresponds to the position of the pin.

[0008] As a further improvement to the above technical solution, two stops are installed at the two vertical ends of the side of the first fixed plate near the first slider, and two first buffer blocks are installed on the side of the first slider near the first fixed plate. The positions of the two first buffer blocks and the two stops correspond to each other and are used to limit the movement of the first slider.

[0009] A second aspect of the present invention provides a pipe cutting machine, the pipe cutting machine comprising a base frame, a fourth slide rail, a pushing assembly, a chuck assembly, a pipe cutting assembly, multiple side seats and several of the above-mentioned follow-up support structures; The fourth slide rail and the pipe cutting assembly are respectively mounted on the base frame. The side seat is connected to one side of the base frame. The fourth slide rail extends along the length of the pipe. The pusher assembly and the chuck assembly are slidably connected to the fourth slide rail. The pipe cutting assembly is used to cut the pipe. The chuck assembly is used to clamp the pipe. The first fixing plate of each follow-up support structure is mounted on a corresponding side seat.

[0010] As a further improvement to the above technical solution, the pipe cutting machine also includes a fifth slide rail, which extends along the length of the pipe. The fourth slide rail is installed on the top surface of the base frame, and the fifth slide rail is installed on one side of the base frame. The pushing assembly and the chuck assembly are slidably connected to the fifth slide rail.

[0011] As a further improvement to the above technical solution, the base frame includes a first sub-frame, a second sub-frame, a first connecting plate, and a second connecting plate. One end of the first sub-frame is connected to one side of the first connecting plate, and one end of the second sub-frame is connected to one side of the second connecting plate.

Detailed Implementation

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The following is combined Figures 1 to 7 Embodiments of the present invention will be described.

[0019] Reference Figures 1 to 3 This embodiment relates to a follow-up support structure 77, including: a first fixed plate 1, a support mechanism and a clamping mechanism; The support mechanism includes a first slide rail 21, a first slider 22, a rack 23, a gear 24, a drive motor 25, a first fixing block 26, and a support roller 27. The first slide rail 21 and the rack 23 are respectively vertically mounted on the first fixing plate 1. The first slider 22 is slidably connected to the first slide rail 21. The gear 24 is meshed with the rack 23. The fixed end of the drive motor 25 is mounted on the first slider 22. The output shaft of the drive motor 25 is coaxially rotatably connected to the gear 24. The drive motor 25 drives the gear 24 to rotate, so that the first slider 22 moves vertically along the first slide rail 21. There are two first fixing blocks 26. The lower ends of the two first fixing blocks 26 are respectively mounted on two adjacent sides of the first slider 22 near the first fixing plate 1. The support roller 27 is rotatably connected to the upper ends of the two first fixing blocks 26. The support roller 27 is located above the first slider 22 and is used to support the pipe 8. The clamping mechanism is mounted on the first slider 22 and is used to clamp the pipe 8 laterally.

[0020] In this embodiment, the follow-up support structure 77, through the cooperation of the support mechanism and the clamping mechanism, simultaneously supports and clamps the tube 8 to be processed. The drive motor 25 drives the gear 24 to move along the rack 23, enabling the first slider 22 and the support roller 27 to be vertically adjusted to accommodate tubes 8 of different heights. The support roller 27 provides support for the tube 8, reducing sagging deformation during the processing of long tubes 8. The clamping mechanism provides lateral restraint for the tube 8, reducing rotation or vibration of the tube 8 and improving stability and processing accuracy during the cutting process. The overall structure enables follow-up support for the tube 8, which is beneficial for improving the processing quality of long and heavy tubes 8 by the tube cutting machine. By installing the support roller 27 of the support mechanism above the first slider 22 in the structural design, the support roller 27, the fixed block, and the first slider 22 form a vertical structural support. The clamping mechanism is directly installed on the first slider 22 of the support mechanism, simplifying the structure of the follow-up support structure 77, reducing the volume of the support mechanism, and enhancing structural stability.

[0021] Specifically, the first slide rail 21 and rack 23 are vertically fixed to the surface of the first fixed plate 1. The first slider 22 slides in cooperation with the first slide rail 21, and the drive motor 25 is fixed on the first slider 22, with its output shaft connected to the gear 24. During operation, the control system issues an adjustment command according to the height of the pipe 8, and the drive motor 25 drives the gear 24 to rotate. Since the gear 24 meshes with the rack 23, the first slider 22 moves up and down along the first slide rail 21. The two first fixed blocks 26 move synchronously with the first slider 22 and drive the support roller 27 to rise and fall. When the pipe 8 is conveyed to the support position, the support roller 27 contacts the lower surface of the pipe 8, supporting the pipe 8. Since the support roller 27 can rotate freely, no large frictional resistance is generated during the axial movement or rotation of the pipe 8. The clamping mechanism is installed on the first slider 22 and adjusts its height synchronously with the first slider 22, so that the clamping center always corresponds to the support center, thereby achieving stable support and clamping of pipes 8 of different specifications.

[0022] Reference Figure 1 In some embodiments, the clamping mechanism includes a second fixed plate 31, a second slide rail 321, a second slider 322, a third slide rail 331, a push plate 34, a cylinder 35, two clamping members 36, two third sliders 332, two connecting rods 37, and two second fixed blocks 38. The second fixed plate 31 is connected to the side of the two first fixed blocks 26 away from the first fixed plate 1. The second slide rail 321 is vertically mounted on the second fixed plate 31, and the third slide rail 331 is horizontally mounted on the second fixed plate 31. The second slider 322 is slidably connected to the second slide rail 321, and the two third sliders 332 are slidably connected to the third slide rail 331 respectively. The lower ends of the two clamping members 36 are... Two third sliders 332 are respectively installed on the side of one of the two third sliders 332 near the other third slider 332. One end of each of the two connecting rods 37 is hinged to the two third sliders 332 respectively, and the other end is hinged to the second slider 322 respectively. Two second fixing blocks 38 are installed on the side of the second slider 322 away from the first slider 22. The push plate 34 is connected to the side of the two second fixing blocks 38 away from the second slider 322. The fixed end of the cylinder 35 is installed on the second fixing plate 31, and the movable end of the cylinder 35 is connected to the push plate 34 for transmission. The cylinder 35 drives the push plate 34 to move vertically. The two clamping members 36 are brought closer or further apart by the two connecting rods 37.

[0023] In this embodiment, a linkage clamping mechanism is formed by the second slide rail 321, the third slide rail 331, the connecting rod 37, and the cylinder 35. A single cylinder 35 can synchronously drive the two clamping members 36 to move in opposite directions, thereby achieving automatic centering clamping of the pipe 8. The structure is simple, the operation is reliable, and it can adapt to the clamping requirements of pipes 8 of different diameters, improving clamping efficiency and clamping stability.

[0024] Specifically, the second fixing plate 31 is fixed to the two first fixing blocks 26. The second slide rail 321 is vertically installed in the middle of the second fixing plate 31, and the second slider 322 is installed on the second slide rail 321. The third slide rail 331 is horizontally arranged on the second fixing plate 31, and the third slider 332 is installed thereon. The two clamping members 36 are respectively fixed to the corresponding third sliders 332. One end of the two connecting rods 37 is hinged to the corresponding third sliders 332, and the other end is hinged to the second slider 322 together. Through the connection of the two second fixing blocks 38, a hinge space is formed between the two connecting rods 37 on the second slider 322. The cylinder 35 is installed on the second fixing plate 31, and its piston rod is connected to the push plate 34. When the cylinder 35 retracts, the second slider 322 moves downward, the connecting rods 37 swing in the opposite direction, and the third sliders 332 on both sides move towards the middle along the third slide rail 331, so that the two clamping members 36 approach and clamp the tube 8 simultaneously. When the cylinder 35 extends, the push plate 34 drives the second slider 322 to move upward, the connecting rod 37 swings and pushes the third sliders 332 on both sides to move outward, and the clamping member 36 releases the pipe 8.

[0025] Reference Figure 1 In some embodiments, the clamping mechanism further includes a pin 371, the push plate 34 is provided with a notch 341, the two connecting rods 37 are hinged to the second slider 322 through the pin 371, and the notch 341 corresponds to the position of the pin 371.

[0026] In this embodiment, a notch 341 is provided on the push plate 34, and the position of the notch 341 corresponds to the position of the pin 371, which facilitates assembly and maintenance.

[0027] Specifically, a notch 341 is provided in the middle of the push plate 34, corresponding to the location of the pin 371. The pin 371 passes through the two connecting rods 37 and the second slider 322 to form a rotating pair. During assembly and maintenance, it is not necessary to remove the push plate 34; the pin 371 can be operated through the notch 341.

[0028] Reference Figure 3In some embodiments, two stops 41 are installed at the two vertical ends of the side of the first fixed plate 1 near the first slider 22, and two first buffer blocks 42 are installed on the side of the first slider 22 near the first fixed plate 1. The positions of the two first buffer blocks 42 and the two stops 41 are corresponding to each other and are used to limit the movement of the first slider 22.

[0029] In this embodiment, the stop block 41 and the first buffer block 42 cooperate to form a stroke limiting structure, which can prevent the first slider 22 from exceeding the designed stroke range. At the same time, the buffer block absorbs collision energy, reduces impact force, reduces equipment wear, and improves the service life of the mechanism.

[0030] Specifically, two stops 41 are respectively installed at the upper and lower ends of the first fixed plate 1. Two first buffer blocks 42 are fixed to the back of the first slider 22 and correspond to the upper and lower stops 41 respectively. When the drive motor 25 drives the first slider 22 to rise to the highest position, the upper first buffer block 42 contacts the upper stop 41; when the first slider 22 descends to the lowest position, the lower first buffer block 42 contacts the lower stop 41. The buffer blocks can be made of rubber, polyurethane, or elastic composite materials, which absorb impact loads during contact, thereby preventing direct collision between metal parts.

[0031] Reference Figure 4 This embodiment relates to a pipe cutting machine, which includes a base frame 5, a fourth slide rail 61, a pusher assembly 71, a chuck assembly 72, a pipe cutting assembly 73, multiple side seats 74, and several of the above-mentioned follow-up support structures 77. The fourth slide rail 61 and the pipe cutting assembly 73 are respectively mounted on the base frame 5. The side seat 74 is connected to one side of the base frame 5. The fourth slide rail 61 extends along the length of the pipe 8. The pusher assembly 71 and the chuck assembly 72 are slidably connected to the fourth slide rail 61. The pipe cutting assembly 73 is used to cut the pipe 8. The chuck assembly 72 is used to clamp the pipe 8. The first fixing plate 1 of each follower support structure 77 is mounted on a corresponding side seat 74.

[0032] In this embodiment, multiple follow-up support structures 77 are set on the pipe cutting machine, which can support and clamp the pipe 8 at multiple positions according to the length of the pipe 8, effectively preventing the long pipe 8 from sagging, swinging and vibrating, improving cutting accuracy and cutting quality, and expanding the applicability of the equipment.

[0033] Specifically, multiple side seats 74 are installed at intervals on the side of the base frame 5 along the conveying direction of the pipe 8, and follower support structures 77 are installed on the side seats 74 as needed. During processing, the pusher assembly 71 feeds the pipe 8 into the chuck assembly 72, which clamps the pipe 8 and drives it to rotate. The multiple follower support structures 77 adjust their height according to the diameter of the pipe 8 and support the pipe 8 at the corresponding positions. As the cutting position changes, each support structure continuously provides support to the pipe 8, keeping the pipe 8 stable throughout the processing. The pipe cutting assembly 73 completes the cutting according to the set program.

[0034] Reference Figure 4 and Figure 5 In some embodiments, the pipe cutting machine further includes a fifth slide rail 62, which extends along the length of the pipe 8. The fourth slide rail 61 is mounted on the top surface of the base frame 5, and the fifth slide rail 62 is mounted on one side of the base frame 5. The pusher assembly 71 and the chuck assembly 72 are slidably connected to the fifth slide rail 62.

[0035] In this embodiment, the fifth slide rail 62 and the fourth slide rail 61 together form a dual guide structure, with one flat mounting and one side mounting. Compared with the method of using only flat mounting or side mounting, the load is more balanced, which is conducive to ensuring cutting accuracy and efficiency. It can also improve the guiding accuracy and anti-tipping ability of the pusher assembly 71 and the chuck assembly 72 during the movement process, reduce running vibration, and improve feeding and clamping stability.

[0036] Specifically, the fourth slide rail 61 is installed on the top of the base frame 5, and the fifth slide rail 62 is installed on the side of the base frame 5. The two slide rails are arranged parallel to each other along the conveying direction of the pipe 8. The pusher assembly 71 and the chuck assembly 72 are connected to the fourth slide rail 61 and the fifth slide rail 62, respectively. During movement, the two slide rails work together to guide the material, keeping the pusher assembly 71 and the chuck assembly 72 in a stable position and preventing tilting due to uneven load. Furthermore, the side-mounted fifth slide rail 62 can be lubricated by side oiling, which is more beneficial to the service life of the fifth slide rail 62 and the slider mounted on it, and keeps the chuck stable during operation.

[0037] In some embodiments, the base frame 5 includes a first sub-frame 51, a second sub-frame 52, a first connecting plate 53, and a second connecting plate 54. One end of the first sub-frame 51 is connected to one side of the first connecting plate 53, and one end of the second sub-frame 52 is connected to one side of the second connecting plate 54. The side of the first connecting plate 53 away from the first sub-frame 51 is connected to the side of the second connecting plate 54 away from the second sub-frame 52.

[0038] In this embodiment, the base frame 5 adopts a split structure design, which is combined and connected by the first connecting plate 53 and the second connecting plate 54. This facilitates transportation and installation, ensures the structural strength of the whole machine, and improves the assembly flexibility of the equipment.

[0039] Specifically, the first sub-frame 51 and the second sub-frame 52 respectively constitute the main structures on both sides of the base frame 5. A first connecting plate 53 is installed at the end of the first sub-frame 51, and a second connecting plate 54 is installed at the end of the second sub-frame 52. During installation, the two connecting plates are attached to each other and connected using bolts or other connection structures, or welded to fix them, so that the first sub-frame 51 and the second sub-frame 52 form an integral frame structure. This structure can meet the manufacturing and transportation requirements of long-size pipe cutting machines.

[0040] Reference Figure 6 In some embodiments, the pipe cutting machine further includes a variable diameter wheel assembly 75, which is mounted on the base frame 5 and is located between the follower support structure 77 and the chuck assembly 72, which is closest to the chuck assembly 72.

[0041] In this embodiment, after setting the variable diameter wheel assembly 75, the pipe 8 before entering the chuck assembly 72 can be guided and its position adjusted, so that pipes 8 of different specifications can smoothly enter the clamping area, improve the equipment's adaptability to pipes 8 of various diameters, and facilitate the stable rotation of the pipe 8 near the cutting position, thereby improving the cutting speed and accuracy.

[0042] Specifically, the reducing wheel assembly 75 is installed between the follower support structure 77 and the chuck assembly 72. When the pipe 8 is conveyed towards the chuck, the pipe 8 first passes through the reducing wheel assembly 75. The reducing wheels provide rolling guidance to the outer wall of the pipe 8, correcting the position of the pipe 8 and gradually aligning its axis with the center of the chuck, thereby improving the subsequent clamping accuracy.

[0043] Reference Figure 7 In some embodiments, the pusher assembly 71 is slidably connected to the fourth slide rail 61 via a fourth slider 711. The fourth slider 711 is provided with a limiting member on the side near the chuck assembly 72. The limiting member includes a bracket 712 and a second buffer block 713. One end of the bracket 712 is connected to the fourth slider 711, and the second buffer block 713 is installed at the other end of the bracket 712.

[0044] In this embodiment, by setting a limiting member and a second buffer block 713, the end point of the pusher assembly 71's movement can be buffered and protected, avoiding rigid collisions between the pusher assembly 71 and other mechanisms, thereby improving the safety and service life of the equipment.

[0045] Specifically, the bracket 712 is fixed to the front end of the fourth slider 711, and the second buffer block 713 is installed at the front end of the bracket 712. When the pushing assembly 71 moves to its limit position, the second buffer block 713 first contacts the corresponding limit part. The second buffer block 713 undergoes elastic deformation to absorb the impact energy, causing the pushing assembly 71 to gradually stop moving, thereby reducing collision damage.

[0046] Reference Figure 1 In some embodiments, the pipe cutting machine further includes a slag baffle 76, which is installed on the fixed end of the chuck assembly 72 and is located between the pipe 8 and the fourth slide rail 61. The slag baffle 76 is used to block impurities from entering the fourth slide rail 61.

[0047] In this embodiment, by setting a baffle plate 76, metal chips, dust and oxide slag generated during the cutting process can be blocked from entering the area of ​​the fourth slide rail 61, thereby avoiding slide rail wear and jamming, improving the reliability of the guiding mechanism and reducing the maintenance frequency.

[0048] Specifically, the baffle plate 76 is fixed to the fixed end of the chuck assembly 72 and moves together with the chuck assembly 72, located between the pipe 8 and the fourth slide rail 61. When the pipe cutting assembly 73 operates, the cutting debris generated splashes downwards. The baffle plate 76 is positioned in the debris's path, blocking and isolating the debris. Impurities fall into the collection area and do not directly enter the fourth slide rail 61 or the interior of the slider, thus keeping the guiding mechanism clean and ensuring long-term stable operation of the equipment.
