Description

Technical Field

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

[0002] In modern industrial production, pipe cutting machines are widely used as efficient and precise processing equipment for cutting materials such as metal pipes and irregularly shaped pipes. Traditional pipe cutting machines typically use a front chuck and a rear chuck in conjunction with a laser cutting device to clamp, transport, and cut the pipes.

[0003] However, in actual operation, especially when cutting long pipes into sections, the unloading process often faces some technical challenges: During the cutting process, the rear chuck is responsible for gradually feeding the pipe to the front chuck. When the pipe is cut into two sections, the rear chuck may still be holding the uncut end. If the rear chuck is released directly, the pipe may get stuck due to a shift in the center of gravity or uneven force, and will not be able to fall smoothly. In a high-speed production environment, the unloading time of each pipe section needs to be strictly controlled. If it is left to fall naturally, the randomness may affect subsequent processes. This unstable unloading phenomenon will directly affect the pipe production efficiency and the continuity of equipment operation.

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

[0037] The following is combined with Figures 1 to 3 The embodiments of this utility model are described below.

[0038] A pipe cutting machine in this embodiment includes:

[0039] The frame 1 has a front chuck 11 and a rear chuck 12 at its two ends along its length.

[0040] A first driving device and a second driving device are both mounted on the frame 1 and are respectively connected to the front chuck 11 and the rear chuck 12 in a transmission manner; the first driving device and the second driving device are used to drive the front chuck 11 and the rear chuck 12 to slide along the length direction of the frame 1.

[0041] A laser cutting device 2 is mounted on the frame 1 and located at the end of the conveying mechanism of the front chuck 11. The laser cutting device 2 is used to cut pipes.

[0042] The material feeding clamping device 3 is mounted on the frame 1 and located behind the cutting point of the laser cutting device 2. The material feeding clamping device 3 is used to clamp the pipe.

[0043] In this embodiment, the frame 1 is the basic support structure of the entire pipe cutting machine. A slide rail 13 is provided along its length. The slide rail 13 is used to guide the sliding of the front chuck 11 and the rear chuck 12, ensuring that the two can move smoothly along the length of the frame 1. The two ends of the frame 1 are respectively provided with a front chuck 11 and a rear chuck 12, which are positioned and moved by a drive device.

[0044] The front chuck 11 is located on the frame 1 near the laser cutting device 2, and is responsible for clamping one end of the tube. It rotates in coordination with the rear chuck 12 during the cutting process.

[0045] The rear chuck 12 is located at the end of the frame 1 away from the laser cutting device 2. It is responsible for gradually conveying the pipe from the feeding mechanism to the front chuck 11. The rear chuck 12 completes the gradual conveying of the pipe by clamping the pipe and gradually releasing and withdrawing it.

[0046] The laser cutting device 2 is mounted on the frame 1 and located at the end of the conveying end of the front chuck 11. After the pipe reaches the predetermined cutting length, the front chuck 11 clamps the pipe and rotates synchronously with the rear chuck 12, and completes the cutting in conjunction with the laser cutting head 26.

[0047] The unloading clamping device 3 is mounted on the frame 1 and located behind the cutting point of the laser cutting device 2. After cutting, the rear chuck 12 remains in a clamping state, and the unloading clamping device 3 is activated to clamp the pipe. At this time, because the unloading clamping device 3 is still clamping the pipe, the rear chuck 12 can release the pipe without jamming and exit smoothly. After the rear chuck 12 exits, the unloading clamping device 3 releases the pipe, allowing the pipe to fall naturally to complete the unloading process.

[0048] The pipe cutting machine of this utility model achieves a smooth transition of pipe dropping through the cooperation of the dropping clamping device 3 and the rear chuck 12, avoiding the problem of dropping failure caused by pipe jamming or unstable center of gravity, ensuring that each section of pipe can drop smoothly, and significantly improving the production efficiency and operational stability of the equipment.

[0049] Specifically, the pipe cutting machine also includes a slide rail 13, which extends along the length of the frame 1. The bottom of the front chuck 11 and the rear chuck 12 are both provided with sliders 14, which are slidably connected to the slide rail 13.

[0050] In this embodiment, the frame 1 is provided with two parallel slide rails 13 extending along its length. The bottom of the front chuck 11 and the rear chuck 12 are respectively provided with two sets of sliders 14 that match the slide rails 13. The sliders 14 are slidably connected to the slide rails 13, so that the front chuck 11 and the rear chuck 12 can slide along the slide rails 13. The two ends of the slide rails 13 correspond to the range of motion of the front chuck 11 and the rear chuck 12, respectively. The cooperation between the slide rails 13 and the sliders 14 provides a precise movement path for the front chuck 11 and the rear chuck 12, ensuring the stability of the pipe conveying process.

[0051] Specifically, the first driving device includes a motor 15, a gear 16, and a rack 17; the rack 17 extends along the length of the frame 1 and is parallel to the slide rail 13; the motor 15 is mounted on the rear chuck 12, and the output end of the motor 15 is connected to the gear 16 for transmission; the gear 16 meshes with the rack 17; when the motor 15 is working, the gear 16 meshes with the rack 17 to drive the rear chuck 12 to slide along the slide rail 13.

[0052] In this embodiment, the first driving device is selected as a motor 15 and a gear 16 and rack 17 transmission system; when the motor 15 is working, its output end drives the gear 16 to rotate; the gear 16 meshes with the rack 17 to transmit the rotational motion of the motor 15 into the linear motion of the rear chuck 12, so that the slider 14 at the bottom of the rear chuck 12 slides along the slide rail 13, thus completing the precise movement of the chuck 12.

[0053] The rear chuck 12 is responsible for gradually feeding the pipe to the front chuck 11. During this process, precise distance control is required, and the pipe needs to move within a large range. Therefore, the motor 15 is selected as the power source. The motor 15 has a stronger power output capability and can work with the gear 16 and rack 17 transmission system to achieve high-precision positioning, ensuring that the distance of each feeding is accurate and avoiding pipe shaking or jamming caused by sudden acceleration or deceleration. The parallel design of the rack 17 and the slide rail 13 ensures that the moving direction of the rear chuck 12 is completely consistent with that of the slide rail 13, avoiding movement deviation caused by the tilting or deviation of the rack 17.

[0054] Specifically, the first drive device further includes a felt wheel 18 and an oil pump; the felt wheel 18 is disposed on the rear chuck 12 and meshes with the rack 17; the oil pump is disposed on the frame 1 and is pipe-connected to the felt wheel 18 and the slide rail 13, and the oil pump is used to supply oil to the felt wheel 18 and the slide rail 13.

[0055] In this embodiment, the oil pump supplies oil to the felt wheel 18 through the oil supply pipeline; after the felt wheel 18 absorbs the lubricating oil, it spreads it evenly on the surface of the rack 17; at the same time, some of the lubricating oil flows to the slide rail 13 through the pipeline, reducing the friction between the slider 14 and the slide rail 13; the introduction of the lubrication system significantly reduces the friction between the gear 16 and the rack 17, and between the slider 14 and the slide rail 13, avoiding vibration or noise problems caused by dry friction while improving transmission efficiency; oil lubrication also reduces the risk of equipment wear, effectively extending the service life of the gear 16, rack 17, slide rail 13 and slider 14, making the equipment operation more stable.

[0056] Specifically, the second driving device includes a driving cylinder 19; the fixed part of the driving cylinder 19 is fixedly connected to the frame 1, and the movable part of the driving cylinder 19 is pulsatorically connected to the front chuck 11. The driving cylinder 19 is used to drive the front chuck 11 to slide along the slide rail 13.

[0057] In this embodiment, the second driving device is selected as a cylinder transmission system. When the driving cylinder 19 is activated, its movable part pushes or pulls the front chuck 11 to slide along the slide rail 13. The front chuck 11 has a small range of movement and is mainly responsible for accurately positioning the pipe before cutting. Compared with the motor 15 drive, the cylinder drive has a faster response speed, which is suitable for the short-distance rapid positioning requirements of the front chuck 11 before cutting.

[0058] Specifically, the frame 1 is provided with limiting baffles 5 at both ends along its length; limiting blocks 51 are provided below the front chuck 11 and the rear chuck 12; when the front chuck 11 or the rear chuck 12 moves along the slide rail 13 to the end of its stroke, the limiting block 51 abuts against the limiting baffles 5 to restrict the movement of the front chuck 11 or the rear chuck 12.

[0059] In this embodiment, the limiting baffles 5 are located at both ends of the frame 1 along its length. One baffle is located at the end of the rear chuck 12's retraction path to limit the maximum retraction distance of the rear chuck 12, and the other baffle is located at the end of the front chuck 11's forward path to limit the maximum forward distance of the front chuck 11. Limiting blocks 51 are provided below the front chuck 11 and the rear chuck 12. When the front chuck 11 or the rear chuck 12 moves along the slide rail 13 to the end of its stroke, the limiting blocks 51 and the limiting baffles 5 abut against each other, thereby limiting the front chuck 11 and the rear chuck 12 from continuing to move. The limiting baffles 5, as rigid limits, restrict the range of motion of the front chuck 11 and the rear chuck 12, effectively preventing the front chuck 11 and the rear chuck 12 from going out of bounds due to misoperation or abnormal conditions of the drive device, thereby ensuring the safety and stability of the equipment.

[0060] Specifically, the material unloading clamping device 3 includes a connector 31, a first cylinder 32, and two first clamping arms 33; the first cylinder 32 includes a fixed part located at the center and movable parts located at both ends; the fixed part of the first cylinder 32 is fixedly connected to the frame 1 through the connector 31; the two movable parts of the first cylinder 32 are respectively connected to the two first clamping arms 33 in a transmission connection; when the first cylinder 32 extends or retracts, its two movable parts drive the two first clamping arms 33 to complete the release or clamping action.

[0061] In this embodiment, the connector 31 is a common sheet metal component, which is used to firmly connect the first cylinder 32 to the frame 1 and fix it after the cutting point of the laser cutting device 2; the first cylinder 32 includes a fixed part located in the center and movable parts located at both ends of the fixed part. The fixed part is fixedly connected to the frame 1 through the connector 31 to ensure that the cylinder remains stable during operation. The movable parts are located at both ends of the cylinder and can move linearly when the cylinder extends or retracts; there are two first clamping arms 33, which are respectively connected to the two movable parts of the first cylinder 32.

[0062] When the material clamping device 3 is in its initial state, i.e., the unclamped state, the two movable parts of the first cylinder 32 are extended, causing the two first clamping arms 33 to move away from each other. After the laser cutting device 2 completes the cutting, the rear chuck 12 still clamps one end of the tube. At this time, the two movable parts of the first cylinder 32 retract, causing the two clamping arms to move closer to each other and finally clamp the cut tube. Subsequently, the rear chuck 12 releases the tube and retracts. After the rear chuck 12 retracts, the two movable parts of the first cylinder 32 extend, causing the two clamping arms to move away from each other, causing the clamping arms to release the tube, and the tube falls naturally under the action of gravity.

[0063] Compared to traditional chucks, the material feeding clamping device 3 has greater adaptability. It can reliably clamp the cut irregular-shaped pipes through the cooperation of the two clamping arms. The rapid response capability of the first cylinder 32 enables the clamping and releasing actions to be completed efficiently, improving the overall operating efficiency of the equipment.

[0064] The orderly cooperation between the material dropping clamping device 3 and the rear chuck 12 effectively solves the problem of material dropping failure caused by pipe jamming or unstable center of gravity in traditional pipe cutting machines, ensuring that each section of pipe can be dropped smoothly.

[0065] Specifically, the pipe cutting machine further includes a second cylinder 4 and a second clamping arm 41; the fixed part of the second cylinder 4 is fixedly connected to the front chuck 11, and the movable part of the second cylinder 4 is throttle connected to the second clamping arm 41; there are two sets of the second cylinder 4 and the second clamping arm 41, and the two sets of the second cylinder 4 and the second clamping arm 41 are arranged opposite to each other on both sides of the feed inlet of the front chuck 11; when the movable parts of the two second cylinders 4 extend, the two second clamping arms 41 move closer to each other to clamp the pipe; when the movable parts of the two second cylinders 4 retract, the two second clamping arms 41 move further apart to release the pipe.

[0066] In this embodiment, the second cylinder 4 and the second clamping arm 41 are used to cooperate with the front chuck 11 and the rear chuck 12 to complete the pipe conveying. The working principle is as follows: During the process of the rear chuck 12 conveying the pipe to the front chuck 11, when the pipe reaches the conveying inlet of the front chuck 11, the second cylinder 4 is activated and its movable part is extended. The movable parts of the two second cylinders 4 respectively drive the two second clamping arms 41 to move closer to each other until the two second clamping arms 41 cooperate to clamp the pipe. Then, the rear chuck 12 releases the pipe and moves back to the initial position to clamp the rear end of the pipe again. After the rear chuck 12 clamps again, the movable parts of the two second cylinders 4 retract, causing the two second clamping arms 41 to move away from each other and release the pipe. At this time, the rear chuck 12 clamps the pipe again and conveys it forward. The above process is repeated until the pipe reaches the required cutting length. When the pipe reaches the predetermined length, the front chuck 11 clamps the pipe, and the front and rear chucks 12 rotate synchronously to cooperate with the laser cutting device 2 to complete the cutting.

[0067] The design of the second cylinder 4 and the second clamping arm 41 enables the pipe to be clamped in time after the rear chuck 12 releases the pipe, ensuring that the pipe will not shake or fall off during the transportation process. Through the coordinated operation of the second cylinder 4, the second clamping arm 41, the rear chuck 12 and the front chuck 11, a complete pipe transportation and clamping process is formed, which improves the efficiency of pipe transportation.

[0068] Specifically, the laser cutting device 2 includes a Z-axis slide 21, a Z-axis drive device 22, an X-axis slide 23, an X-axis drive device 24, an A-axis turntable 25, and a laser cutting head 26. The Z-axis slide 21 is slidably connected to the frame 1 via the Z-axis drive device 22, and the Z-axis drive device 22 is used to drive the Z-axis slide 21 to move along the Z-axis direction. The X-axis slide 23 is slidably connected to the Z-axis slide 21 via the X-axis drive device 24, and the X-axis drive device 24 is used to drive the X-axis slide 23 to move along the X-axis direction. The A-axis turntable 25 is disposed on the X-axis slide 23, and the laser cutting head 26 is disposed on the A-axis turntable 25, and the A-axis turntable 25 is used to drive the laser cutting head 26 to rotate along the A-axis.

[0069] In this embodiment, under the control of the A-axis turntable 25, the laser cutting head 26 rotates within a range of ±50° to change the cutting angle, enabling the laser cutting head 26 to not only perform straight cutting of pipes but also bevel cutting of pipes. Furthermore, combined with the drive of the X-axis drive device 24 and the Z-axis drive device 22, the laser cutting head 26 achieves precise positioning and cutting in three-dimensional space.

[0070] Specifically, the pipe cutting machine also includes a receiving plate 6; the receiving plate 6 is disposed on the frame 1 and located at the end of the conveying of the front chuck 11; the receiving plate 6 is used to receive pipe materials.

[0071] In this embodiment, the receiving plate 6 is fixedly installed on the frame 1 and located at the end of the conveying of the front chuck 11, ensuring that the receiving plate 6 can accurately receive the pipes that fall naturally after being released from the dropping clamping device 3, avoiding scattering or damage caused by improper falling position; in addition, the receiving plate 6 is usually designed to be slightly inclined, with the inclined direction facing the pipe stacking area, so that the falling pipes can slide smoothly and be stacked neatly, which is convenient for subsequent collection or transfer operations.
