Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting equipment, and in particular to a feeding rack and an automatic feeding tube cutting machine. Background Technology

[0002] In modern industrial production, pipe cutting machines are widely used as efficient and precise processing equipment for cutting metal pipes. Pipe cutting machines usually need to be used in conjunction with a loading rack, which transports the pipes to the rear chuck, and then the front and rear chucks work together with a laser cutting device to complete the cutting of the pipes.

[0003] However, when the pipe to be cut is long, a considerable portion of the pipe will be suspended at the tail of the rear chuck. Existing feed racks lack effective support and radial restraint mechanisms for this suspended section of the pipe. This causes the pipe, suspended between the rear chuck and feed rack, to easily swing and vibrate during high-speed cutting, resulting in radial vibration. This vibration can lead to instability in the relative position of the cutting head and the pipe, causing deviations in the cut dimensions and severely affecting cutting accuracy.

[0004] It is clear that there is room for improvement in the existing technology. Utility Model Content

[0043] The following is combined with Figures 1 to 6 The embodiments of this utility model are described below.

[0044] A feeding rack in this embodiment includes:

[0045] A frame 1, on which an installation rail 2 extends along its length;

[0046] Multiple support wheels 21 are distributed on the mounting rail 2, and the support wheels 21 are used to support the pipe material;

[0047] A clamping cylinder 3 is slidably mounted on the mounting rail 2; the clamping cylinder 3 includes a fixed part and movable parts located at both ends of the fixed part; each of the two movable parts of the clamping cylinder 3 is provided with a clamping plate 31;

[0048] A conveying mechanism is provided on the mounting rail 2; the conveying mechanism is connected to the fixed part of the clamping cylinder 3 for transmission, and the conveying mechanism is used to drive the clamping cylinder 3 to slide along the mounting rail 2.

[0049] In this embodiment, the pipe is placed on a support surface composed of multiple support wheels 21. The support wheels 21 are distributed on the mounting track 2, which can accommodate pipes of different diameters and provide stable support, preventing the pipe from rolling or shifting on the mounting track 2, and ensuring the stability of the pipe's posture before entering subsequent processes. The clamping cylinder 3 is slidably mounted on the mounting track 2, and its fixed part is connected to the conveying mechanism. When it is necessary to clamp the pipe, the two movable parts of the clamping cylinder 3 retract, driving the clamping plate 31 to firmly clamp the pipe, so that it can move along the mounting track while clamping the pipe. The track 2 slides; the conveying mechanism transmits power to the fixed part of the clamping cylinder 3 through mechanical transmission, thereby driving the clamping cylinder 3 to move smoothly along the installation track 2 and finally feed it into the subsequent pipe cutting machine. During this process, the clamping cylinder 3 always maintains the clamping state of the pipe, ensuring that the pipe will not experience radial vibration or axial displacement. This utility model effectively solves the problem of insufficient cutting accuracy of the subsequent pipe cutting machine due to the lack of a radial vibration limiting mechanism in the cutting process of long pipes in the existing feeding rack, significantly improving the stability of pipe conveying and cutting accuracy, and meeting the needs of high-speed and high-precision pipe cutting operations.

[0050] Specifically, the feeding rack further includes a first slider 32, a first slide rail 33, and a connecting plate 34; the first slide rail 33 is disposed on the mounting rail 2, the first slider 32 is slidably connected to the first slide rail 33, and the first slider 32 is connected to the fixing part of the clamping cylinder 3 and the conveying mechanism through the connecting plate 34.

[0051] In this embodiment, the first slide rail 33 is set on the mounting rail 2, providing a stable sliding path for the first slider 32. The first slider 32 is slidably connected to the first slide rail 33, ensuring that the clamping cylinder 3 and its fixing part can move smoothly on the mounting rail 2, avoiding movement deviation caused by friction or vibration. The first slider 32 is connected to the fixing part of the clamping cylinder 3 and the conveying mechanism through the connecting plate 34, thereby transmitting the power of the conveying mechanism to the clamping cylinder 3. When the conveying mechanism is started, the power is transmitted to the first slider 32 through the transmission connection, causing the first slider 32 to slide along the first slide rail 33. Since the first slider 32 is connected to the fixing part of the clamping cylinder 3 through the connecting plate 34, the clamping cylinder 3 moves smoothly along the mounting rail 2. During this process, the clamping cylinder 3 always maintains the clamping state of the pipe, ensuring that the pipe will not experience radial vibration or axial displacement.

[0052] Specifically, the conveying mechanism includes a servo motor 4, two gears 41, a rack 42, and two bearing seats 43; the two gears 41 are respectively mounted on the mounting rail 2 via the two bearing seats 43, and are located at both ends of the first slide rail 33; the rack 42 meshes with the two gears 41, and the rack 42 is drivenly connected to the connecting plate 34; the servo motor 4 is mounted on the mounting rail 2, and the output end of the servo motor 4 is drivenly connected to one of the gears 41.

[0053] In this embodiment, two gears 41 are fixed to the mounting rail 2 via two bearing seats 43 and are located at both ends of the first slide rail 33. A rack 42 meshes with the two gears 41 and is connected to the first slider 32 via a connecting plate 34, thus indirectly connecting to the fixed part of the clamping cylinder 3. A servo motor 4 is mounted on the mounting rail 2, and its output end is connected to one of the gears 41. When the servo motor 4 starts, its output power is transmitted to the rack 42 via the gear 41, causing the rack 42 to move along the mounting rail 2. Because the rack 42 is connected to the connecting plate 34, the first slider 32 slides along the first slide rail 33, thereby causing the clamping cylinder 3 to move smoothly along the mounting rail 2. Throughout the conveying process, the speed of the rack 42 is adjusted by adjusting the output parameters of the servo motor 4, thus adapting to the conveying requirements of pipes of different specifications.

[0054] Specifically, the loading rack further includes multiple first lead screw drive mechanisms 24, a first synchronous drive shaft 23, and a first adjusting handle 22; the multiple first lead screw drive mechanisms 24 are distributed on the frame 1, and their output ends are connected to the bottom of the mounting track 2; the multiple first lead screw drive mechanisms 24 are coaxially connected through the first synchronous drive shaft 23, and the first synchronous drive shaft 23 is connected to the first adjusting handle 22; when the first adjusting handle 22 is rotated, the output ends of the multiple first lead screw drive mechanisms 24 extend or retract synchronously to adjust the height of the mounting track 2.

[0055] In this embodiment, the first lead screw transmission mechanism 24, the first synchronous drive shaft 23, and the first adjusting handle 22 constitute a lifting mechanism. When it is necessary to adjust the height of the mounting rail 2 to accommodate pipes of different diameters, the operator only needs to rotate the first adjusting handle 22. The rotation of the first adjusting handle 22 is transmitted to multiple first lead screw transmission mechanisms 24 through the first synchronous drive shaft 23, causing their output ends to extend or retract synchronously. Since the output ends of the first lead screw transmission mechanisms 24 are connected to the bottom of the mounting rail 2, the mounting rail 2 is raised or lowered accordingly.

[0056] In practical applications, the height adjustment of the mounting track 2 directly affects the position of the support wheel 21, thereby changing the axial height of the pipe. When pipes of different diameters are placed on the support wheel 21, their axial height will change. If the height of the mounting track 2 remains fixed, the axis of the pipe may not be collinear with the axis of the rear chuck 91 of the pipe cutter, thus affecting the cutting accuracy and processing quality. By introducing a lifting mechanism to precisely adjust the height of the mounting track 2, the height of the mounting track 2 can be flexibly adjusted according to the change of pipe diameter, ensuring that the axis of the pipe always remains collinear with the axis of the rear chuck 91, meeting the requirements of high-precision cutting.

[0057] Specifically, the feeding rack further includes a mounting plate 5, two second sliders 52, a second slide rail 51, a drive cylinder 54, and two pull rods 53; the mounting plate 5 is disposed on the mounting rail 2, the second slide rail 51 is disposed on the mounting plate 5, and the second slide rail 51 is orthogonal to the mounting rail 2 in the horizontal direction; the two second sliders 52 are slidably connected to the second slide rail 51 respectively, and each of the two second sliders 52 is vertically provided with a clamping post 55; the fixed part of the drive cylinder 54 is disposed on the mounting plate 5, and its movable part extends along the length direction of the mounting rail 2; the two second sliders 52 are respectively hinged to the movable part of the drive cylinder 54 through the two pull rods 53.

[0058] In this embodiment, to further ensure that the pipe can be stably clamped and fixed during the process of being conveyed to the chuck 91 of the pipe cutter, a second clamping mechanism is designed. The second clamping mechanism includes a mounting plate 5, two second sliders 52, a second slide rail 51, a drive cylinder 54, and two pull rods 53. The second clamping mechanism works in conjunction with the clamping cylinder 3. When the clamping cylinder 3 completes the conveying task and retracts, it continues to clamp and fix the pipe, thereby ensuring that the pipe will not shake or shift during the operation of the pipe cutter. Specifically, in the initial state, the movable part of the drive cylinder 54 is in the extended position. When the pipe is in the outgoing state, the two second sliders 52 are separated by the pull rod 53, which drives the clamping column 55 to separate, leaving space for the pipe to enter the clamping area. When the clamping cylinder 3 delivers the pipe to the outlet side of the mounting track 2, the movable part of the drive cylinder 54 retracts, and the pull rod 53 pulls the two second sliders 52 to move towards each other along the second slide rail 51. At this time, the two clamping columns 55 gradually approach and finally clamp the pipe, achieving further fixation of the pipe. During the process of the clamping cylinder 3 releasing the pipe and retracting to the middle section to prepare for the next clamping and delivery, the second clamping mechanism continues to maintain the clamping and fixing of the pipe.

[0059] The main function of the clamping cylinder 3 is to transport the pipe from back to front, so its position is set in the middle of the mounting track 2; while a second clamping mechanism is set on the conveying outlet side to make up for the lack of clamping capacity of the clamping cylinder 3 during the retraction, and to ensure the stability of the entire conveying and cutting process.

[0060] Specifically, the feeding rack further includes multiple conveying units; the multiple conveying units are spaced apart along the length of the frame 1; each conveying unit includes a fixed clamp 71, a pull belt 72, a fixed pulley 73, a take-up wheel 74, and a counterweight 75; the fixed clamp 71 and the take-up wheel 74 are respectively disposed at the top and bottom of the frame 1; the fixed pulley 73 is disposed on the frame 1; one end of the pull belt 72 is fixedly connected to the fixed clamp 71, and the other end of the pull belt 72 passes over the fixed pulley 73 and is wound around the take-up wheel 74; the pull belt 72 is also provided with a counterweight 75, which causes the pull belt 72 located between the fixed clamp 71 and the fixed pulley 73 to drop downward to form a suspended support surface, which is used to support the pipe; the take-up wheel 74 deforms the suspended support surface of the pull belt 72 into a flat conveying surface by winding the pull belt 72, so that the pipe placed on the pull belt 72 rolls along the flat conveying surface.

[0061] In this embodiment, in each conveying unit, one end of the pull belt 72 is fixedly connected to the fixing clamp 71 at the top of the frame 1, and the other end passes over the fixed pulley 73 set on the frame 1 and is wound around the take-up wheel 74 at the bottom of the frame 1. The pull belt 72 is provided with a counterweight 75, which causes the pull belt 72 located between the fixing clamp 71 and the fixed pulley 73 to drop downward, forming a natural hanging support surface. This hanging support surface is used to support the pipes, and the operator can place the pipes to be loaded on the hanging support surface. When the pipes need to be conveyed to the subsequent process, the take-up wheel 74 begins to wind the pull belt 72. As the pull belt 72 is gradually tightened by the take-up wheel 74, the originally suspended pull belt 72 gradually deforms into a straight conveying surface. At this time, the pipe placed on the pull belt 72 rolls along the straight conveying surface of the pull belt 72 due to gravity and enters the subsequent process, and finally falls on the support wheel 21 on the installation track 2. Since the pipe is usually long, a single pull belt 72 cannot meet the support requirements. Therefore, multiple conveying units work together to support and convey the pipe. The suspended support surface of each pull belt 72 and the subsequently formed straight conveying surface can effectively bear part of the weight of the pipe, ensuring that the entire conveying process is stable and reliable.

[0062] Specifically, the feeding rack also includes a second synchronous drive shaft 76 and a main motor 77; the main motor 77 is mounted on the frame 1, and its output end is connected to the second synchronous drive shaft 76; the winding wheels 74 of the plurality of conveying units are connected to each other via the second synchronous drive shaft 76.

[0063] In this embodiment, there are a large number of conveying units, and they need to support and convey long pipes simultaneously. If the actions of the winding wheels 74 are not synchronized, some of the pull belts 72 may straighten too early or too late, causing pipe deviation, jamming, or other instability. To address this, a second synchronous drive shaft 76 and a main motor 77 are introduced. When the main motor 77 starts, its output power is transmitted to the second synchronous drive shaft 76 through a transmission connection. The winding wheels 74 of multiple conveying units achieve precise synchronous action through the second synchronous drive shaft 76, ensuring that the straightening speed of each pull belt 72 is consistent. This avoids pipe deviation or jamming caused by asynchronous action of a single winding wheel 74, ensuring the stability of the entire conveying process.

[0064] Specifically, the feeding rack also includes multiple vertically arranged partition plates 8 on the frame 1; the multiple partition plates 8 are spaced apart along the length direction of the frame 1; each partition plate 8 is provided with an interconnected material distribution groove 81 and a feeding groove 82; the material distribution groove 81 extends along the straight conveying surface; the feeding groove 82 extends along the height direction of the partition plate 8 and is located in the vertical projection area of ​​the mounting track 2; the partition plate 8 is provided with a material blocking cylinder 83, the fixed part of the material blocking cylinder 83 is fixedly connected to the partition plate 8, and the movable part of the material blocking cylinder 83 extends and retracts toward the material distribution groove 81. The material distribution trough 81 is interrupted; the feeding rack also includes a third slider 84, a third slide rail 85, and a pipe diameter adjustment plate 86; the third slider 84 is disposed on the partition plate 8, the third slide rail 85 is slidably connected to the third slider 84, and the extension direction of the third slide rail 85 is the same as the width direction of the material distribution trough 81; the pipe diameter adjustment plate 86 is provided on the third slide rail 85, and the free end of the pipe diameter adjustment plate 86 extends toward the material distribution trough 81; when the third slide rail 85 slides along the third slider 84, it drives the pipe diameter adjustment plate 86 to move along the width direction of the material distribution trough 81, so as to adjust the effective passing width of the material distribution trough 81.

[0065] In this embodiment, the material distribution trough 81 extends along the straight conveying surface of the conveying unit. When the pipe rolls to the end along the straight conveying surface of the pull belt 72, it enters the material distribution trough 81. The material distribution trough 81 receives the pipe that slides off the pull belt 72 and guides it to the inlet of the feeding trough 82. The feeding trough 82 extends along the height direction of the partition plate 8, and because it is located in the vertical projection area of ​​the mounting track 2, the pipe can accurately fall above the mounting track 2 and be supported by the support wheel 21, preparing for subsequent clamping and conveying.

[0066] Each partition plate 8 is equipped with a material blocking cylinder 83, whose fixed part is fixedly connected to the partition plate 8, and whose movable part extends and retracts toward the material distribution trough 81; by controlling the extension or retraction of the movable part of the material blocking cylinder 83, the material distribution trough 81 can be blocked or opened, and the number of pipes entering the material distribution trough 81 each time can be precisely controlled to avoid jamming or confusion caused by multiple pipes entering at the same time.

[0067] When the third slider 84 slides along the third slide rail 85, it drives the pipe diameter adjustment plate 86 to move along the width direction of the material distribution groove 81, partially blocking the material distribution groove 81, thereby adjusting the effective passing width of the material distribution groove 81 so that the material distribution groove 81 can adapt to pipes of different diameters and ensure that the pipes can pass through smoothly.

[0068] Specifically, the feeding rack further includes a third synchronous drive shaft 87, a second adjusting handle 88, and a plurality of second lead screw transmission mechanisms 89; the output parts of the plurality of second lead screw transmission mechanisms 89 are respectively connected to the third slider 84; the plurality of second lead screw transmission mechanisms 89 are coaxially connected through the third synchronous drive shaft 87, and the third synchronous drive shaft 87 is connected to the second adjusting handle 88; when the second adjusting handle 88 rotates, the output ends of the plurality of second lead screw transmission mechanisms 89 extend or retract synchronously to drive the third slider 84 to slide along the third slide rail 85.

[0069] In this embodiment, since there are multiple partition plates 8 and corresponding pipe diameter adjustment plates 86, if the actions of each pipe diameter adjustment plate 86 are not synchronized, the width of each material distribution groove 81 may be different, making it impossible for the pipe to fall smoothly into the material distribution groove 81. To address this, a third synchronous drive shaft 87, a second adjustment handle 88, and a second lead screw transmission mechanism 89 are introduced. After rotating the second adjustment handle 88, the multiple second lead screw transmission mechanisms 89 achieve precise synchronous action through the third synchronous drive shaft 87, ensuring that the moving distance of all pipe diameter adjustment plates 86 is consistent, avoiding the problem of uneven width of the material distribution groove 81 caused by the asynchronous action of a single pipe diameter adjustment plate 86, and ensuring the stability of the entire adjustment process.

[0070] An automatic feeding and pipe cutting machine includes a frame 9, on which a rear chuck 91, a front chuck, and a laser cutting device are provided. The automatic feeding and pipe cutting machine also includes the feeding rack described in the above embodiment. The center line of the mounting track 2 coincides with the axis of the rear chuck 91, and the clamping center of the clamping plate 31 is collinear with the axis of the rear chuck 91.

[0071] In this embodiment, the automatic feeding and pipe cutting machine includes: a frame 9, with a front chuck and a rear chuck 91 respectively at both ends in the length direction; and a laser cutting device, which is mounted on the frame 9 and located at the end of the conveying of the front chuck, and the laser cutting device is used to cut pipes.

[0072] The center line of the mounting track 2 of the feeding rack coincides with the axis of the rear chuck 91 of the pipe cutter. This design ensures that the pipe can be accurately aligned with the position of the rear chuck 91 when it is conveyed along the mounting track 2. The clamping center of the clamping plate 31 on the clamping cylinder 3 is collinear with the axis of the rear chuck 91. This design ensures that the pipe can maintain a stable posture and smoothly enter the clamping range of the rear chuck 91 when it is conveyed to the vicinity of the rear chuck 91 by the clamping cylinder 3.

[0073] The overall workflow of the automatic feeding and pipe cutting machine is as follows: Pipes placed on the suspended support surface of the conveyor belt 72 are first conveyed to the distribution trough 81 by the conveying unit; then, the material distribution is controlled by the material blocking cylinder 83, and the pipe diameter is controlled by the pipe diameter adjustment plate 86, allowing qualified pipes to pass through the distribution trough 81 and be guided by the feeding trough 82 to the top of the installation track 2, where they are finally received by the support wheel 21 on the installation track 2; subsequently, the clamping cylinder 3 precisely conveys the pipes along the installation track 2 to the vicinity of the rear chuck 91 via the conveying mechanism; the clamping cylinder... 3. During the release and retraction process, the second clamping mechanism on the exit side of the mounting track 2 continues to clamp and fix the pipe, ensuring that the pipe will not shake or shift when the pipe cutter is working; finally, the pipe is transported to the rear chuck 91, and the pipe is cut through the cooperation of the rear chuck 91, the front chuck and the laser cutting device; in this embodiment, the automatic feeding pipe cutter, from feeding to transportation to cutting, achieves stable fixing of the pipe through the cooperation of the clamping cylinder 3 and the second clamping mechanism, avoiding the problem of reduced cutting accuracy caused by pipe shaking or shifting.
