Abstract
Description
Technical Field
[0001] The present invention relates to the field of laser tube cutting equipment, and in particular to a feeding rack and an automatic feeding tube cutting machine. Background Art
[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 coordinated with a loading rack, which transports the pipe to the rear chuck. The front and rear chucks then work with the laser cutting device to complete the pipe cutting. However, when the pipe to be cut is long, a long section of the pipe will be left hanging at the rear chuck. The existing feeder lacks effective support and radial restraint for the hanging section of the pipe. As a result, when the pipe cutter is cutting at high speed, the pipe hanging between the rear chuck and the feeder is prone to swinging, causing radial vibration. This vibration can easily cause the relative position of the pipe cutter head and the pipe to become unstable, resulting in deviations in the cut pipe size and seriously affecting cutting accuracy.

DETAILED DESCRIPTION
[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0020] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0021] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, and "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" is solely for the purpose of distinguishing technical features and should not be understood to indicate or imply relative importance, or to implicitly indicate the number or order of the technical features indicated. "And / or" throughout the text represents three parallel solutions. For example, "A and / or B" means a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0024] The following combination Figures 1 to 6 Embodiments of the present invention are described.
[0025] A loading rack in this embodiment includes: A frame 1 is provided with a mounting rail 2 extending along its length; A plurality of support wheels 21 are distributed on the mounting rail 2, and the support wheels 21 are used to receive pipes; A clamping cylinder 3 is slidably disposed on the mounting rail 2; the clamping cylinder 3 comprises a fixed portion and movable portions located at both ends of the fixed portion; clamping plates 31 are provided on both movable portions of the clamping cylinder 3; A conveying mechanism is provided on the mounting track 2 ; the conveying mechanism is in driving connection with a fixed portion of the clamping cylinder 3 , and the conveying mechanism is used to drive the clamping cylinder 3 to slide along the mounting track 2 .
[0026] In this embodiment, the pipe is placed on a supporting surface composed of a plurality of support wheels 21; the support wheels 21 are distributed on the mounting rail 2, which can adapt to pipes of different diameters and provide stable support to prevent the pipe from rolling or deflecting on the mounting rail 2, thereby ensuring the posture stability of the pipe before entering the subsequent process; the clamping cylinder 3 is slidably arranged on the mounting rail 2, and its fixed part is connected to the conveying mechanism by transmission; when the pipe needs to be clamped, the two movable parts of the clamping cylinder 3 contract, driving the clamping plate 31 to clamp the pipe firmly, so that it can clamp the pipe while moving along the mounting rail 2. The mounting 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 mounting track 2 and finally feeding it into the subsequent pipe cutting machine. During this process, the clamping cylinder 3 always maintains a clamping state on the pipe to ensure that the pipe does not vibrate radially or deviate axially. The present invention effectively solves the problem of insufficient cutting accuracy of the subsequent pipe cutting machine due to the lack of a radial jitter limiting mechanism in the existing feeding rack during the long pipe cutting process, significantly improves the stability and cutting accuracy of pipe transportation, and meets the needs of high-speed and high-precision pipe cutting operations.
[0027] Specifically, the loading rack also includes a first slider 32, a first slide rail 33 and a connecting plate 34; the first slide rail 33 is arranged on the mounting rail 2, the first slider 32 is slidingly connected to the first slide rail 33, and the first slider 32 is connected to the fixed part of the clamping cylinder 3 and the conveying mechanism through the connecting plate 34.
[0028] In this embodiment, the first slide rail 33 is arranged on the mounting rail 2, providing a stable sliding path for the first slider 32; the first slider 32 ensures that the clamping cylinder 3 and its fixed part can move smoothly on the mounting rail 2 through a sliding connection with the first slide rail 33, avoiding movement deviation caused by friction or vibration; the first slider 32 is transmission-connected to the fixed 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, driving the first slider 32 to slide along the first slide rail 33; since the first slider 32 is connected to the fixed 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 a clamping state on the pipe, ensuring that the pipe does not experience radial jitter or axial displacement.
[0029] 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 arranged on the mounting track 2 through the two bearing seats 43, and are respectively located at the two ends of the first slide rail 33; the rack 42 is engaged with the two gears 41, and the rack 42 is transmission connected to the connecting plate 34; the servo motor 4 is arranged on the mounting track 2, and the output end of the servo motor 4 is transmission connected to one of the gears 41.
[0030] 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, thereby indirectly connecting to the fixed portion of the clamping cylinder 3. A servo motor 4 is disposed on the mounting rail 2, with its output end connected to one of the gears 41. When the servo motor 4 is started, its output power is transmitted to the rack 42 via the gear 41, driving the rack 42 to move along the mounting rail 2. Due to the transmission connection between the rack 42 and the connecting plate 34, the first slider 32 slides along the first slide rail 33, thereby driving the clamping cylinder 3 to move smoothly along the mounting rail 2. During the entire conveying process, the movement speed of the rack 42 is adjusted by adjusting the output parameters of the servo motor 4, thereby adapting to the conveying requirements of pipes of different specifications.
[0031] Specifically, the loading rack also includes multiple first screw transmission mechanisms 24, first synchronous drive shafts 23 and first adjustment handles 22; multiple first screw transmission mechanisms 24 are distributed on the frame 1, and their output ends are transmission connected to the bottom of the mounting rail 2; multiple first screw transmission mechanisms 24 are coaxially connected through the first synchronous drive shaft 23, and the first synchronous drive shaft 23 is transmission connected to the first adjustment handle 22; when the first adjustment handle 22 rotates, the output ends of multiple first screw transmission mechanisms 24 are synchronously extended or retracted to adjust the height of the mounting rail 2.
[0032] In this embodiment, the first screw transmission mechanism 24, the first synchronous drive shaft 23, and the first adjustment handle 22 constitute a lifting mechanism. When the height of the mounting rail 2 needs to be adjusted to accommodate pipes of different diameters, the operator only needs to rotate the first adjustment handle 22. The rotation of the first adjustment handle 22 is transmitted to the multiple first screw transmission mechanisms 24 via the first synchronous drive shaft 23, causing their output ends to extend or retract synchronously. Since the output ends of the first screw transmission mechanisms 24 are in transmission connection with the bottom of the mounting rail 2, the mounting rail 2 is raised or lowered accordingly. In actual application, the height adjustment of the mounting rail 2 directly affects the position of the support wheel 21, thereby changing the axial center height of the pipe. When pipes of different diameters are placed on the support wheel 21, their axial center heights will change; if the height of the mounting rail 2 is fixed, the axis of the pipe may not be collinear with the axis of the rear chuck 91 of the pipe cutting machine, thereby affecting the cutting accuracy and processing quality; by introducing a lifting mechanism to accurately adjust the height of the mounting rail 2, the height of the mounting rail 2 can be flexibly adjusted according to changes in the diameter of the pipe, ensuring that the axis of the pipe always remains collinear with the axis of the rear chuck 91, meeting the needs of high-precision cutting.
[0033] Specifically, the loading rack also includes a mounting plate 5, two second sliders 52, a second slide rail 51, a driving cylinder 54 and two pull rods 53; the mounting plate 5 is arranged on the mounting rail 2, the second slide rail 51 is arranged 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 respectively slidably connected to the second slide rail 51, and the two second sliders 52 are vertically provided with a clamping column 55; the fixed part of the driving cylinder 54 is arranged 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 driving cylinder 54 through the two pull rods 53.
[0034] In this embodiment, in order to further ensure that the pipe can be stably clamped and fixed during the process of being conveyed to the rear chuck 91 of the pipe cutting machine, 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 driving 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 retreats, it continues to clamp and fix the pipe, thereby ensuring that the pipe will not shake or deflect when the pipe cutting machine is working; specifically, in the initial state, the movable part of the driving cylinder 54 is in the extended position. In the out state, the two second sliders 52 drive the clamping columns 55 to separate through the pull rod 53, leaving space for the pipe to enter the clamping area; when the clamping cylinder 3 conveys the pipe to the exit side of the mounting rail 2, the movable part of the driving cylinder 54 contracts, and the two second sliders 52 are pulled toward each other along the second slide rail 51 through the pull rod 53; at this time, the two clamping columns 55 gradually approach and finally clamp the pipe, thereby further fixing the pipe; while the clamping cylinder 3 releases the pipe and retreats to the middle section to prepare for the next clamping and conveying, the second clamping mechanism continues to clamp and fix the pipe; 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 section of the mounting track 2; and a second clamping mechanism is set on the conveying outlet side to make up for the lack of clamping ability of the clamping cylinder 3 during the retreat period of the pipe, ensuring the stability of the entire conveying and cutting process.
[0035] Specifically, the loading rack also includes a plurality of conveying units; the plurality of conveying units are spaced apart along the length direction of the frame 1; the conveying unit includes a fixing clamp 71, a pull belt 72, a fixed pulley 73, a winding wheel 74 and a counterweight block 75; the fixing clamp 71 and the winding wheel 74 are respectively arranged at the top and bottom of the frame 1; the fixed pulley 73 is arranged on the frame 1; one end of the pull belt 72 is fixedly connected to the fixing clamp 71, and the other end of the pull belt 72 is wound around the fixed pulley 73 and then wound around the winding wheel 74; a counterweight block 75 is also provided on the pull belt 72, and the counterweight block 75 causes the pull belt 72 located between the fixing clamp 71 and the fixed pulley 73 to fall and form a hanging supporting surface, and the hanging supporting surface is used to support the pipe; the winding wheel 74 deforms the hanging supporting 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.
[0036] In this embodiment, in each conveying unit, one end of the pull belt 72 is fixedly connected to the fixed clamp 71 on the top of the frame 1, and the other end passes around the fixed pulley 73 set on the frame 1 and is wound around the reel 74 at the bottom of the frame 1; a counterweight block 75 is provided on the pull belt 72, which causes the pull belt 72 located between the fixed clamp 71 and the fixed pulley 73 to fall down, forming a natural hanging support surface; the hanging support surface is used to support the pipes, and the operator can place the pipes that need to be loaded on the hanging support surface; when the pipes need to be conveyed to the subsequent process, the reel 74 starts to wind up the pull belt 72, As the pull belt 72 is gradually tightened by the wind-up wheel 74, the originally suspended pull belt 72 gradually deforms into a flat conveying surface; at this time, the pipe placed on the pull belt 72 rolls along the flat conveying surface of the pull belt 72 due to the action of gravity, enters the subsequent process, and finally falls on the support wheel 21 on the installation track 2; because the pipe is usually long, a single pull belt 72 cannot meet the supporting requirements, so multiple conveying units work together to support and convey the pipe. The suspended supporting surface of each pull belt 72 and the subsequently formed flat conveying surface can effectively bear part of the weight of the pipe, ensuring that the entire conveying process is smooth and reliable.
[0037] Specifically, the loading rack also includes a second synchronous drive shaft 76 and a main motor 77; the main motor 77 is arranged on the frame 1, and its output end is transmission-connected to the second synchronous drive shaft 76; the winding wheels 74 of the multiple conveying units are transmission-connected through the second synchronous drive shaft 76.
[0038] In this embodiment, there are a large number of conveying units, and long pipes need to be supported and conveyed at the same time. If the movements of the reel wheels 74 are not synchronized, some of the pull belts 72 may be straightened too early or too late, thereby causing pipe deviation, jamming or other instability. For this reason, a second synchronous drive shaft 76 and a main motor 77 are introduced. When the main motor 77 is started, the power it outputs is transmitted to the second synchronous drive shaft 76 through a transmission connection. The reel wheels 74 of multiple conveying units achieve precise synchronous movement through the second synchronous drive shaft 76, ensuring that the straightening speed of each pull belt 72 is consistent, avoiding pipe deviation or jamming caused by the asynchronous movement of a single reel wheel 74, and ensuring the smoothness of the entire conveying process.
[0039] Specifically, the loading rack also includes a plurality of partition plates 8 vertically arranged on the frame 1; the plurality of partition plates 8 are spaced apart along the length direction of the frame 1; each of the partition plates 8 is provided with a material dividing trough 81 and a material feeding trough 82 that are connected to each other; the material dividing trough 81 is extended along the flat conveying surface; the material feeding trough 82 extends along the height direction of the partition plate 8 and is located in the vertical projection area of the mounting track 2; a material blocking cylinder 83 is provided on the partition plate 8, the fixed part of the material blocking cylinder 83 is fixedly connected to the partition plate 8, the movable part of the material blocking cylinder 83 is extended toward the material dividing trough 81, and the movable part of the material blocking cylinder 83 extends The material distribution trough 81 is separated from the material distribution trough 81; the loading rack also includes a third slider 84, a third slide rail 85 and a tube diameter adjustment plate 86; the third slider 84 is arranged on the partition plate 8, and 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 third slide rail 85 is provided with a tube diameter adjustment plate 86, and the free end of the tube 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 tube diameter adjustment plate 86 to move along the width direction of the material distribution trough 81 to adjust the effective passing width of the material distribution trough 81.
[0040] In this embodiment, the material distribution trough 81 is extended along the flat conveying surface of the conveying unit. When the pipe rolls along the flat conveying surface of the pull belt 72 to the end, it enters the material distribution trough 81, which receives the pipe sliding down from the pull belt 72 and guides it to the entrance 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 rail 2, the pipe can accurately fall onto the mounting rail 2 and be supported by the support wheel 21, ready for subsequent clamping and conveying. Each partition plate 8 is provided with a material blocking cylinder 83, the fixed portion of which is fixedly connected to the partition plate 8, and the movable portion is extended and retracted toward the material distribution trough 81; by controlling the movable portion of the material blocking cylinder 83 to extend or retract, the material distribution trough 81 can be isolated or opened, and the number of pipes entering the material distribution trough 81 each time can be accurately controlled to avoid jamming or confusion caused by multiple pipes entering at the same time; 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 trough 81, partially blocking the material distribution trough 81, thereby adjusting the effective passing width of the material distribution trough 81, so that the material distribution trough 81 can adapt to pipes of different diameters, ensuring that the pipes can pass smoothly.
[0041] Specifically, the loading rack also includes a third synchronous drive shaft 87, a second adjustment handle 88 and multiple second screw transmission mechanisms 89; the output parts of the multiple second screw transmission mechanisms 89 are respectively connected to the third slider 84; multiple second 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 adjustment handle 88; when the second adjustment handle 88 rotates, the output ends of the multiple second screw transmission mechanisms 89 are synchronously extended or retracted to drive the third slider 84 to slide along the third slide rail 85.
[0042] In this embodiment, since there are multiple partition plates 8 and corresponding pipe diameter adjustment plates 86; if the movements of each pipe diameter adjustment plate 86 are not synchronized, the widths of each distribution trough 81 may be different, so that the pipe cannot fall smoothly into the distribution trough 81; for this reason, a third synchronous drive shaft 87, a second adjustment handle 88 and a second screw transmission mechanism 89 are introduced; after rotating the second adjustment handle 88, multiple second screw transmission mechanisms 89 achieve precise synchronous movement through the third synchronous drive shaft 87, ensuring that the moving distances of all pipe diameter adjustment plates 86 are consistent, avoiding the problem of uneven width of the distribution trough 81 caused by the asynchronous movement of a single pipe diameter adjustment plate 86, and ensuring the smoothness of the entire adjustment process.
[0043] An automatic loading 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 loading and pipe cutting machine also includes the loading frame 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.
[0044] In this embodiment, the automatic feeding and pipe cutting machine includes: a frame 9, with a front chuck and a rear chuck 91 respectively provided at both ends in the longitudinal direction; a laser cutting device, which is arranged on the frame 9 and located at the conveying end side of the front chuck, and is used to cut the pipe; The center line of the mounting track 2 of the loading rack coincides with the axis of the rear chuck 91 of the pipe cutting machine. This design ensures that the pipe can be accurately aligned with the position of the rear chuck 91 when it is transported 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 when the pipe is transported to the vicinity of the rear chuck 91 by the clamping cylinder 3, it can maintain a stable posture and smoothly enter the clamping range of the rear chuck 91. The overall working process of the automatic feeding and pipe cutting machine is as follows: the pipe placed on the hanging support surface of the pull belt 72 is first transported to the material 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, so that qualified pipes can pass through the material distribution trough 81, and are guided by the feeding trough 82 to the top of the installation track 2, and finally are received by the support wheel 21 on the installation track 2; then, the clamping cylinder 3 accurately transports the pipe along the installation track 2 to the vicinity of the rear chuck 91 through the conveying mechanism; in the clamping cylinder During the loosening and retraction process, the second clamping mechanism at the outlet side of the mounting track 2 continues to clamp and fix the pipe, ensuring that the pipe does not shake or deflect when the pipe cutting machine is working; finally, the pipe is transported to the rear chuck 91, and the pipe cutting is completed through the cooperation of the rear chuck 91, the front chuck and the laser cutting device; the automatic loading and pipe cutting machine of this embodiment, from loading to transportation to cutting, all achieves stable fixation 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 deviation.
