Description

An automatic pipe cutting machine Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to an automatic tube cutting machine for receiving materials. Background Technology

[0002] To improve cutting stability and facilitate the collection of cut pipes for easy handling and transport by operators, many laser pipe cutting machines are equipped with receiving racks for automatic material receiving. However, with advancements in laser pipe cutting technology, to reduce waste, the front chuck is designed for short-range movement, allowing it to be moved in front of or behind the laser cutting head as needed. But because the receiving plate of existing automatic receiving racks is fixed in position, a relatively large distance is maintained between the receiving plate and the front chuck to prevent interference during movement. This results in the receiving plate being unable to effectively catch the cut pipes when cutting short sections. This not only affects the overall efficiency of the equipment but may also lead to instability or damage to the pipes during the cutting process.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

The receiving plate is in a horizontal state or a downward tilting state under the drive of the tilting drive cylinder. A unloading platform for connecting with the receiving plate is provided on one side of the base frame.

[0007] As a further improvement to the above technical solution, the side bracket is provided with a Y-axis guide rail extending in the front-rear direction. The front chuck includes a first side slide plate, a front chuck body disposed on the first side slide plate, and a first displacement cylinder fixed on the side bracket. The first side slide plate is slidably connected to the Y-axis guide rail via a Y-axis slider. The displacement cylinder is drivenly connected to the first side slide plate, driving the front chuck body to be positioned in front of or behind the laser cutting assembly.

[0008] As a further improvement to the above technical solution, the rear chuck assembly includes a second side slide plate, a rear chuck body disposed on the second side slide plate, a Y-axis drive motor disposed on the second side slide plate, and a first gear disposed on the output end of the Y-axis drive motor.

[0009] As a further improvement to the above technical solution, the displacement driving mechanism is a second displacement cylinder that is laterally mounted on the base frame, and the piston rod end of the second displacement cylinder is connected to the slide via a transmission block.

[0010] As a further improvement to the above technical solution, the base frame is provided with two first guide rails extending in the front and rear directions, and the bottom of the carriage is provided with a first slider that is slidably connected to the first guide rails.

[0011] As a further improvement to the above technical solution, the lifting mechanism includes a receiving rack vertically mounted on a vertical frame, a reducer mounted on a bracket, a lifting drive motor connected to the input end of the reducer, a transmission shaft connected to the output end of the reducer via a coupling, and a second gear sleeved on the transmission shaft; the second gear meshes with the receiving rack.

[0012] As a further improvement to the above technical solution, the vertical frame is provided with a vertically extending second guide rail, and the bracket is provided with a second slider that is slidably connected to the second guide rail.

During normal cutting, the rear end of the receiving plate can be brought closer to the front chuck, shortening the distance between them and placing the receiving plate in a suitable working position. When the front chuck moves to the front of the laser cutting head, the slide and components can move forward synchronously to avoid interference, effectively solving the problem of motion interference. It can effectively receive long, short, and tail-end materials, improving the applicability of the equipment. Attached Figure Description

Detailed Implementation

[0025] This utility model provides an automatic material receiving pipe cutting machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 6. This utility model provides an automatic receiving pipe cutting machine, including a side hanger 11, a gantry frame 12 disposed near the tail of the side hanger 11, and multiple support frames 13 disposed beside the side hanger 11. The gantry frame 12 is located in front of all the support frames 13. A rear chuck assembly 2 and a front chuck assembly 6 movable along the Y-axis are hung on the side hanger 11. The front chuck assembly 6 is disposed adjacent to the gantry frame 12. A centering follower mechanism 3 is provided on the support frame 13. The centering follower mechanism 3 is used to clamp the pipe and center it. A laser cutting assembly 4 movable along the X-axis and Z-axis is provided on the gantry frame 12. An automatic receiving frame 5 is provided in front of the gantry frame 12. The automatic receiving rack 5 includes a base frame 51, a slide 52 slidably mounted on the base frame 51, a displacement drive mechanism for driving the slide 52 to move back and forth, a bracket 56 fixedly mounted on the slide 52, a vertical frame 55 slidably mounted on the bracket 56, a receiving plate 58 hinged to the top of the vertical frame 55, a tilting drive cylinder 57 mounted on the vertical frame 55 and driving the receiving plate 58 to tilt to the side, and a lifting mechanism mounted on the bracket 56 and driving the vertical frame 55, the receiving plate 58 and the tilting drive cylinder 57 to lift synchronously. The receiving plate 58 is in a horizontal state or a downward tilting state under the drive of the tilting drive cylinder 57. A unloading platform 59 for connecting with the receiving plate 58 is provided on one side of the base frame 51.

[0027] In normal cutting conditions, the front chuck assembly 6 is located behind the laser cutting head. At this time, the displacement drive mechanism, based on the length of the tube and the position of the front chuck, drives the carriage 52 and its components to move backward, bringing the rear end of the receiving plate 58 as close as possible to the front chuck assembly 6, shortening the distance between them, and placing the receiving plate 58 in a suitable working position. Then, the front chuck assembly 6 and the rear chuck assembly 2 together drive the tube forward and rotate it, causing the laser cutting assembly 4 to emit laser light downwards to cut the tube.

[0028] During the cutting process, the lifting mechanism can drive the vertical frame 55, the receiving plate 58, and the tilting drive mechanism to rise and fall synchronously. This adjusts the height of the receiving plate 58 according to the height of the pipe, ensuring effective follow-up support for the front section of the pipe and preventing it from sagging and affecting cutting accuracy. Whether the material is short or long, it can be supported by the receiving plate 58 during cutting, preventing deformation and ensuring cutting accuracy. After the pipe is cut, it is naturally received by the receiving plate 58. The tilting drive cylinder 57 then activates, driving the receiving plate 58 to tilt to the side, changing it from a horizontal to a downward tilted position. The cut pipe is then automatically discharged under gravity.

[0029] When only a section of the pipe remains, the front chuck assembly 6 moves forward to the front of the laser cutting assembly 4. At the same time, the displacement drive mechanism drives the carriage 52 and the components on the carriage 52 to move forward to avoid the obstruction. However, the rear end of the receiving plate 58 remains close to the front chuck assembly 6. The receiving plate 58 provides follow-up support for the front section of the pipe. The laser cutting assembly 4 cuts off the waste material at the rear end of the pipe. Then, the front chuck assembly releases the waste material and moves backward. The waste material is naturally received by the receiving plate 58. The flipping drive cylinder 57 starts to operate, driving the receiving plate 58 to flip to the side, so that the receiving plate 58 changes from a horizontal state to a downward tilting state. The waste material is automatically discharged under the action of gravity.

[0030] The automatic receiving pipe cutting machine provided by this utility model ingeniously designs the receiving plate 58 on the automatic receiving rack 5 to be flexibly movable. It can drive the slide 52 and related components to move back and forth according to the pipe length and the position of the front chuck assembly 6. During normal cutting, the rear end of the receiving plate 58 can be brought closer to the front chuck assembly 6, shortening the distance between them and placing the receiving plate 58 in a suitable working position. When the front chuck assembly 6 moves to the front of the laser cutting head, the slide 52 and its components can move forward synchronously to avoid interference, effectively solving the problem of motion interference. It can effectively receive long, short, and tail materials, improving the applicability of the equipment.

[0031] Specifically, the side bracket 11 is provided with a Y-axis guide rail extending in the front-to-back direction. The front chuck assembly 6 includes a first side slide plate 61, a front chuck body 62 disposed on the first side slide plate 61, and a first displacement cylinder 63 fixed on the side bracket 11. The first side slide plate 61 is slidably connected to the Y-axis guide rail through a Y-axis slider. The first displacement cylinder 63 is drivenly connected to the first side slide plate 61, driving the front chuck body 62 to be positioned in front of or behind the laser cutting assembly 4. Understandably, after the pipe fittings are slit to reduce their length, a relatively long tail material will still remain due to the constraint of the rear chuck assembly 2 and the front chuck assembly 6 clamping together, making further cutting difficult. Then, the front chuck body 62 releases the pipe material, the laser cutting assembly 4 rises, and the first displacement cylinder 63 drives the front chuck body 62 on the first side slide plate 61 to move in front of the laser cutting assembly 4, so that the rear chuck assembly 2 can continue to move forward and approach the laser cutting assembly 4 without being blocked by the front chuck assembly 6. At this time, the laser cutting assembly 4 is located between the front chuck assembly 6 and the rear chuck assembly 2, and the laser cutting assembly 4 further cuts the tail material, thereby achieving tail material cutting.

[0032] Furthermore, the rear chuck assembly 2 includes a second side slide plate 21, a rear chuck body 22 mounted on the second side slide plate 21, a Y-axis drive motor 24 mounted on the second side slide plate 21, and a first gear mounted on the output end of the Y-axis drive motor 24. The second side slide plate 21 is slidably connected to the Y-axis guide rail via a Y-axis slider. The side bracket 11 is provided with a Y-axis rack 23 extending in the front-rear direction, and the first gear meshes with the Y-axis rack 23 for transmission. Under the drive of the Y-axis drive motor 24, the rear chuck body 22 on the second side slide plate 21 can move smoothly laterally, stably clamping the tail of the tube to achieve movement.

[0033] In practice, since the front chuck body 62 only has two states—in front of the laser cutting head and behind the laser cutting head—the receiving plate 58 only needs to switch between the two positions, simplifying the control logic. Therefore, the displacement drive mechanism is a second displacement cylinder 531 horizontally mounted on the base frame 51. The piston rod end of the second displacement cylinder 531 is connected to the slide 52 via a transmission block. The second displacement cylinder 531 provides a stable and powerful driving force, quickly responding to changes in the position of the pipe and the body 62, rapidly driving the slide 52 to move back and forth, achieving timely adjustment of the receiving plate 58's position, meeting the needs of different cutting conditions, ensuring the efficient operation of the automatic receiving rack 5, and simplifying the overall structure of the device.

[0034] Furthermore, the base frame 51 is provided with two first guide rails 511 extending front and rear, and the bottom of the slide 52 is provided with a first slider 512 that is slidably connected to the first guide rails 511. The first guide rails 511 provide precise guidance for the front and rear movement of the slide 52, ensuring that the slide 52 moves smoothly in the predetermined front and rear direction under the action of the displacement drive mechanism, avoiding instability such as deviation or shaking of the slide 52, and ensuring that the receiving plate 58 can always accurately reach the required position and maintain a suitable distance from the front chuck body 62, thereby achieving efficient material receiving.

[0035] Specifically, the lifting mechanism includes a receiving rack 541 vertically mounted on the vertical frame 55, a reducer 542 mounted on the bracket 56, a lifting drive motor 543 connected to the input end of the reducer 542, a transmission shaft 544 connected to the output end of the reducer 542 via a coupling, and a second gear 545 sleeved on the transmission shaft 544; the second gear 545 meshes with the receiving rack 541. The rotation of the lifting drive motor 543 is reduced and amplified by the reducer 542 before being transmitted to the transmission shaft 544, driving the second gear 545 to rotate in the forward or reverse direction. Because the teeth of the second gear 545 and the receiving rack 541 are precisely matched, the receiving rack 541 will rise or fall a fixed distance for each rotation of a certain angle. This allows for precise control of the lifting height of the vertical frame 55, the receiving plate 58, and the tilting drive mechanism, enabling the receiving plate 58 to accurately adjust its position according to the actual height of the pipe, providing stable follow-up support for the pipe and ensuring cutting accuracy.

[0036] Furthermore, the vertical frame 55 is provided with a vertically extending second guide rail 546, and the bracket 56 is provided with a second slider 547 that is slidably connected to the second guide rail 546. The second guide rail 546 provides precise guidance for the lifting and lowering movement of the vertical frame 55. When the lifting mechanism drives the vertical frame 55, the receiving plate 58, and the tilting drive cylinder 57 to lift and lower synchronously, the second guide rail 546 ensures that the vertical frame 55 moves smoothly and strictly along the vertical direction, avoiding any forward or backward, left or right deviation or swaying of the vertical frame 55 during the lifting and lowering process. This allows the receiving plate 58 to stably reach the target height, providing reliable follow-up support for the pipe and ensuring the stability and cutting accuracy of the cutting process.

[0037] Preferably, the receiving plate 58 has multiple slots 581 arranged in the front-to-back direction, and a guide roller 583 is rotatably mounted at each slot 581, with the axis of the guide roller 583 extending in the left-to-right direction. When the cut pipe falls onto the receiving plate 58, the guide roller 583 can rotate with the rolling of the pipe. Compared to the pipe directly contacting and sliding on the plane of the receiving plate 58, the rolling of the guide roller 583 greatly reduces the friction between the pipe and the receiving plate 58. This makes the movement of the pipe on the receiving plate 58 smoother, reduces scratches or wear on the pipe surface caused by friction, and helps to ensure the surface quality of the pipe.

[0038] Please refer to Figure 7. The centering follow-up mechanism 3 includes a fixed vertical plate 31 fixed on the mounting side seat, a lifting slide plate 32 that can be moved up and down on the fixed vertical plate 31, a lifting drive mechanism 33 for driving the lifting slide plate 32 to move up and down, and a clamping positioning mechanism 34 disposed on the lifting slide plate 32. The clamping positioning mechanism 34 is used to clamp the pipe to a set position to achieve positioning. The top of the lifting slide plate 32 is provided with two supports 35, and the two supports 35 together support a horizontally extending and rotatable support roller 36.

[0039] After the pipe is transported to the support roller 36 by the loading rack or hoisting method, the support roller 36 supports the pipe. The clamping and positioning mechanism 34 first clamps the pipe to the middle of the support roller 36. Then, the lifting drive mechanism 33 lifts the pipe to the set height, so that the pipe is coaxial with the front chuck assembly 6 and the rear chuck assembly 2, so that the front chuck assembly 6 and the rear chuck assembly 2 can clamp the pipe. During the processing, the support roller 36 provides follow-up support for the pipe. When the pipe needs to rotate or interferes with the movement of the rear chuck structure, the lifting drive mechanism 33 controls the components on the lifting slide plate 32 to descend to avoid it.

[0040] It is understood that the clamp positioning mechanism 34, the clamping rod driving mechanism, and the lifting driving mechanism 33 are actually existing technologies, and their specific structures will not be described in detail here.

[0041] Specifically, the laser cutting assembly 4 includes an X-axis sliding mechanism mounted on the gantry 12, a transverse sliding bracket 56 mounted on the X-axis sliding mechanism, a Z-axis sliding mechanism mounted on the longitudinal sliding bracket 56, a vertical sliding bracket 56 mounted on the Z-axis sliding mechanism, and a laser cutting head mounted at the bottom of the vertical sliding bracket 56. The X-axis sliding mechanism includes an X-axis guide rail mounted on the top of the gantry 12, an X-axis rack and pinion, an X-axis drive motor, and a third gear mounted on the main shaft of the X-axis drive motor. The second gear 545 meshes with the X-axis rack for transmission. The longitudinal sliding bracket 56 is slidably connected to the X-axis guide rail via an X-axis slider.

[0042] During operation, the X-axis drive motor drives the third gear to rotate. Under the transmission meshing of the third gear and the X-axis rack, the lateral sliding bracket 56 moves along the X-axis direction, thereby driving the laser cutting head to move along the X-axis direction. When the laser cutting head needs to move along the Z-axis direction, the Z-axis sliding mechanism drives the vertical sliding bracket 56 and the laser cutting head mounted on the vertical sliding bracket 56 to move vertically. It should be noted that when the first displacement cylinder 63 drives the front chuck assembly 6 to move, the Z-axis sliding mechanism needs to drive the laser cutting head to rise to prevent the laser cutting head from colliding with the front chuck assembly 6.

[0043] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
