Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a double-clamp laser tube cutting machine. Background Technology

[0002] With the increasing demands for processing precision and efficiency in modern manufacturing, laser cutting technology has been widely applied in the pipe processing field due to its advantages such as high precision, non-contact processing, and high flexibility. Currently, existing laser pipe cutting equipment is mainly used for complex processing tasks such as cutting, engraving, trimming, and drilling of stainless steel, aluminum, and other metal building material pipes. In related technologies, the pipe is typically fixed by clamping at both ends, and a rotating device drives the pipe to rotate, while a moving laser cutting head is used for localized processing.

[0003] When processing long tubes or continuously along their entire length, this structural design is prone to vibration and displacement of the tube during transport and rotation due to limited support points and uneven clamping force distribution. This leads to instability in the laser focus position, affecting processing accuracy and surface quality. Furthermore, when the tube is nearing its end, the existing clamping mechanism is unable to effectively hold the remaining portion due to structural limitations, resulting in inaccurate laser cutting head positioning and problems such as cut offset and hole misalignment. Since the clamping mechanism cannot cover the last part of the tube, the end area cannot be properly engraved or cut, requiring secondary manual processing, which not only reduces overall processing efficiency but also increases labor intensity and production costs. Utility Model Content

[0004] This utility model provides a dual-clamp laser tube cutting machine, which aims to solve the problems of poor clamping stability and unsatisfactory positioning accuracy in laser tube cutting equipment when continuously processing long tubes, thus affecting the processing accuracy and surface quality of the tubes.

[0005] This utility model discloses a dual-clamp laser tube cutting machine, comprising a machine body, a laser cutting system mounted on the machine body, and a clamping system for conveying and rotating tubes. The clamping system includes a clamp on the machine body and two sets of clamping mechanisms. The two sets of clamping mechanisms are slidably mounted on the machine body. One set of clamping mechanisms is used to clamp, move, and rotate the tube, while the other set of clamping mechanisms is close to the unloading end of the machine body and is used to guide and rotate the tube in coordination with the actions of the clamping mechanism away from the unloading end of the machine body. The clamp is located at one end of the machine body and is used to clamp the tube.

[0006] Preferably, the clamping mechanism includes a connecting seat and a clamping assembly, a rotary drive assembly, and a moving assembly mounted on the connecting seat. The clamping assembly is used to clamp the pipe, the rotary drive assembly is used to drive the clamping assembly to rotate, and the moving assembly is used to drive the connecting seat to slide along the machine body.

[0007] Preferably, a guide rail is fixed on the machine body, and a slider that slides with the guide rail is provided on the connecting seat.

[0008] Preferably, the clamping assembly includes a driving member and a plurality of clamping members, each of the clamping members being slidably connected to the connecting seat, and the driving member driving each of the clamping members to synchronously move closer to or away from the axis of the pipe.

[0009] Preferably, the clamping mechanism near the unloading end of the machine body is further provided with a plurality of guide rollers, each guide roller being rotatably connected to the clamping member, and each guide roller rolling and adhering to the tube.

[0010] Preferably, there are four clamping members, each clamping member is evenly arranged around the circumference of the pipe, and at least two guide rollers are provided on the same clamping member. The guide rollers on two adjacent clamping members are staggered along the axis of the pipe, and the guide rollers on the two clamping members correspond one-to-one and remain flush.

[0011] Preferably, the machine body is further provided with a guide assembly, which includes a lifting cylinder and a rolling support table. The lifting cylinder is connected to a clamping mechanism away from the unloading end of the machine body, and the extended end of the lifting cylinder is rotatably connected to the rolling support table. The rolling support table makes rolling contact with the pipe.

[0012] Preferably, the unloading end of the machine body is provided with a guide plate for guiding the processed pipe material to be unloaded.

[0013] Preferably, the clamp includes a double-headed cylinder and two clamping heads. The double-headed cylinder is mounted on the machine body, and the two protruding ends of the double-headed cylinder are respectively connected to the two clamping heads.

[0014] Preferably, the two clamping heads have gaskets on their opposite end faces.

[0015] The beneficial effects of this utility model are as follows:

[0016] (2) Improved cutting accuracy of pipes. The two sets of clamping mechanisms of the clamping system work together. During the pipe cutting process, one set of clamping components clamps, transports and rotates the pipe, while the other set of clamping components guides the transport and rotation of the pipe, ensuring the stability of the pipe during transport and rotation. This effectively reduces the shaking and deviation of the pipe during the cutting process. In addition, the rolling support on the machine body rolls in contact with the pipe, providing stable support for the pipe. The setting of the rolling support effectively reduces the shaking during the pipe processing, enabling the pipe to maintain a stable state during cutting, thus improving the cutting accuracy and cutting quality of the pipe.

[0017] (2) The entire cutting process is automated, which improves the efficiency of pipe cutting. From pipe clamping, conveying, cutting to unloading, each link is completed automatically by the equipment, reducing manual intervention, improving processing efficiency, and reducing the intensity of manual labor. The dual-clamp design of the dual-clamp laser pipe cutting machine allows clamping mechanism one to continuously convey the pipe to the laser processing area when processing long pipes, while clamping mechanism two plays the role of sliding positioning, so that the pipe can be cut continuously, reducing the time required for pipe clamping and positioning, and improving processing efficiency. Clamping mechanism one and clamping mechanism two can flexibly adjust the clamping method according to the length and shape of the pipe. When processing the tail section of the pipe, clamping mechanism two can move to a suitable position to clamp both ends of the pipe to the maximum extent, so that the middle part of the pipe can be processed, avoiding the situation that some areas cannot be processed due to the short tail section of the pipe. This improves the utilization rate and processing efficiency of the pipe. Attached Figure Description

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 5 As shown, the dual-clamp laser tube cutting machine of this utility model includes a machine body 1, a laser cutting system mounted on the machine body 1, and a clamping system for conveying and rotating the tube 6. The laser cutting system includes a bracket 2 slidably mounted on the machine body 1, and a laser generator 21 and a cutting head 22 mounted on the bracket 2. The laser generator 21 is used to generate a high-energy-density laser beam, and the emitted laser beam serves as the cutting source. The cutting head 22 is used to precisely apply the focused laser beam to the surface of the tube 6 to cut the tube 6.

[0027] The clamping system includes a clamping device and two sets of clamping mechanisms on the machine body 1. For ease of description, the clamping mechanism away from the unloading end of the machine body 1 is referred to as clamping mechanism one, and the clamping mechanism closer to the unloading end of the machine body 1 is referred to as clamping mechanism two. The unloading end of the machine body 1 is provided with an inclined guide plate 12. Clamping mechanism one is used to clamp, move and rotate the pipe 6. Clamping mechanism two cooperates with the action of clamping mechanism one to rotate and move the pipe 6 for guidance. The clamping device is set at the unloading end of the machine body 1 to clamp the pipe 6.

[0028] The clamping mechanism includes a connecting seat 3 and a clamping assembly, a rotary drive assembly 32, and a moving assembly 33 mounted on the connecting seat 3. A guide rail 11 is fixed on the machine body 1. The connecting seat 3 is provided with a slider that slides with the guide rail 11. The connecting seat 3 is slidably assembled with the machine body 1 through the slider and the guide rail 11. The clamping assembly is used to clamp the pipe 6. The clamping assembly includes a drive component and multiple clamping components 31. In this embodiment, there are four clamping components 31, which are evenly arranged around the circumference of the pipe 6. Each clamping component 31 is slidably connected to the connecting seat 3. The drive component drives each clamping component 31 to move synchronously closer to or away from the axis of the pipe 6. When each clamping component 31 moves synchronously closer, it clamps the pipe 6. When each clamping component 31 moves synchronously away, it releases the pipe 6. The rotary drive assembly 32 is used to drive the clamping assembly to rotate, and the moving assembly 33 is used to drive the connecting seat 3 to slide along the machine body 1.

[0029] To ensure the guiding effect of the clamping mechanism 2 on the pipe 6, the clamping mechanism 2 is also equipped with multiple guide rollers 311. Each guide roller 311 is rotatably connected to the clamping member 31, and each guide roller 311 rolls and adheres to the pipe 6. To further increase the stability of the clamping mechanism 2 in guiding the pipe 6, it is preferable to provide two guide rollers 311 on the same clamping member 31 of the clamping mechanism 2. The guide rollers 311 on the two clamping members 31 correspond one-to-one and remain flush, and the guide rollers 311 on adjacent clamping members 31 are staggered. The staggered arrangement of the guide rollers 311 on adjacent clamping members 31 ensures the guidance of the clamping mechanism 2 on the pipe 6, while further ensuring the clamping effect of the clamping mechanism 2 on the pipe 6.

[0030] The clamping device includes a double-headed cylinder 41 and two clamping heads 42. The double-headed cylinder 41 is mounted on the machine body 1 via a mounting bracket 4. The two extended ends of the double-headed cylinder 41 are respectively connected to the two clamping heads 42. The double-headed cylinder 41 drives the two clamping heads 42 to move closer or further away synchronously. When the two clamping heads 42 move closer synchronously, they clamp the pipe 6; when the two clamping heads 42 move further away synchronously, they release the pipe 6. The opposite end faces of the two clamping heads 42 are provided with gaskets. The gaskets can be made of rubber and may also have anti-slip textures. The gaskets increase the friction between the clamping heads 42 and the pipe 6, thereby reducing relative sliding between the pipe 6 and the clamping heads 42, improving the stability of the pipe 6 during processing, and ensuring the cutting quality of the pipe 6.

[0031] The machine body 1 is also equipped with a guide assembly, which includes a lifting cylinder 5 and a rolling support 51. The lifting cylinder 5 is fixed to the connecting seat 3 of the clamping mechanism 1 through a connecting frame. The extended end of the lifting cylinder 5 is rotatably connected to the rolling support 51. The rolling support 51 rolls with the pipe 6. The setting of the rolling support 51 further improves the positioning accuracy of the pipe 6, effectively reduces the shaking of the pipe 6 during the processing, and improves the accuracy of the laser cutting processing of the pipe 6.

[0032] The complete working process of the dual-clamp laser tube cutting machine provided by this utility model is as follows:

[0033] After the tube 6 is fed, the clamping mechanism 1 slides along the machine body 1 and clamps the tube 6. Then, the moving component 33 of the clamping mechanism 1 starts to work, driving the connecting seat 3 to slide along the machine body 1 and move the tube 6 towards the laser processing area. As the clamping mechanism 1 conveys, the tube 6 gradually passes through the clamping component of the clamping mechanism. At this time, the clamping component of the clamping mechanism 2 is in an unclamped state, but its guide roller 311 rolls and adheres to the tube 6, playing a sliding positioning role, so that the tube 6 can move smoothly with the action of the clamping mechanism 1.

[0034] When the tube 6 moves to the appropriate position in the laser processing area, the laser cutting system begins operation. The laser generator 21 produces a high-energy-density laser beam, which, after being focused by the cutting head 22, precisely acts on the surface of the tube 6 to cut it. Simultaneously, the rotation drive component 32 and the moving component 33 of the clamping mechanism one drive the clamping assembly to rotate according to the processing requirements of the tube 6, enabling the tube 6 to undergo circumferential cutting and achieving complex shape cutting. During the cutting process, the clamping mechanism one continuously adjusts the position of the tube 6 according to the cutting program settings, and the moving component 33 moves the tube 6 axially, coordinating with the movement of the laser cutting head 22 to complete the continuous cutting of the tube 6. The clamping mechanism two continuously slides and positions the tube 6 to ensure its stability during the cutting process.

[0035] When the tube 6 is processed to its end, the remaining tube 6 is too short for clamping mechanism one to hold effectively. At this time, clamping mechanism two moves on the machine body 1, positioning the laser working area between clamping mechanism one and clamping mechanism two. Clamping mechanism one and clamping mechanism two work together to clamp both ends of the tube 6 to the maximum extent. At the same time, the double-headed cylinder 41 of the clamping device drives the two clamping heads 42 to move closer synchronously and clamp one end of the tube 6. The clamping device assists in clamping one end of the tube 6, further ensuring the stability of both ends of the tube 6 and facilitating the smooth unloading of the tail section of the tube 6 after the tail end is cut.

[0036] After clamping mechanism one and clamping mechanism two jointly clamp the tube 6, the laser cutting system continues to work, cutting the tail section of the tube 6. The rotary drive assembly 32 of clamping mechanism one and clamping mechanism two work together to enable the tube 6 to be rotated for cutting. The effective cooperation between clamping mechanism one and clamping mechanism two ensures the stability of the tube 6 during the cutting process and guarantees the cutting quality of the tail section of the tube 6. The clamp is used to clamp and fix one end of the tube 6 during the cutting process, and after the tube 6 is processed, it is released so that the tube 6 is fed along the guide plate 12.

[0037] The dual-clamp laser pipe cutting machine provided by this utility model achieves stable clamping, precise conveying, efficient cutting, and smooth unloading of pipes through the coordinated work of various components such as the clamping system, laser cutting system, and guiding components, thus ensuring the quality and efficiency of pipe cutting processing.
