Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a bevel cutting mechanism. Background Art

[0002] With the maturity of laser cutting technology, due to its economic efficiency, laser cutting has been widely used in many fields of the manufacturing industry, which also brings great convenience to the cutting of pipe materials. With the improvement of processing requirements, in addition to being able to cut pipes directly, the laser cutting mechanism also needs to have the function of bevel cutting. The existing laser cutting mechanisms are mainly installed on the gantry beam on the bed of the laser pipe cutting machine. Since the front and rear positions of the laser cutting mechanism cannot be changed, the cutting flexibility is poor, resulting in longer tail materials of workpieces and more damage and waste. In addition, the structure of the gantry beam makes the overall height of the bed of the laser pipe cutting machine relatively large, which is not convenient for container loading and transportation.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

[0004] In view of the above deficiencies of the existing technology, the purpose of the utility model is to provide a bevel cutting mechanism to improve the cutting flexibility.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

Detailed implementation manners

[0020] The present utility model provides a bevel cutting mechanism. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0021] In this article, the X-axis direction is the left-right direction, the Y-axis direction is the front-back direction, and the Z-axis direction is the up-down direction.

[0022] Please refer to Figures 1-4 , the present utility model provides a bevel cutting mechanism, including a T-shaped frame 1, a Y-axis slide seat 2 slidably arranged on the flat plate 11 of the T-shaped frame 1 in the front-back direction, a Y-axis driving mechanism 3 for driving the Y-axis slide seat 2 to move, an X-axis slide seat 4 slidably arranged on the Y-axis slide seat 2 in the left-right direction, an X-axis driving mechanism 5 for driving the X-axis slide seat 4 to move, an A-axis turntable 6 arranged on one side surface of the X-axis slide seat 4, and a laser cutting head 71 arranged on the A-axis turntable 6 through a mounting bracket 72; a Z-axis driving mechanism 8 for driving the T-shaped frame 1 to move up and down is arranged on the vertical plate 12 of the T-shaped frame 1.

[0023] In practical applications, the bevel cutting mechanism is located behind the chuck. The chuck transports the pipe towards the bevel cutting mechanism and clamps the pipe during cutting. The A-axis turntable 6 controls the laser cutting head 71 to rotate within the range of ±45° to change the cutting angle, enabling the laser cutting head 71 to not only perform straight cutting but also bevel cutting of the pipe. Moreover, combined with the driving of the X-axis driving mechanism 5 and the Z-axis driving mechanism 8, precise positioning and cutting of the laser cutting head 71 in the three-dimensional space are achieved. When there is remaining tail material of the pipe, the A-axis turntable 6 controls the laser cutting head 71 to face vertically downward, and the Y-axis driving mechanism 3 drives the Y-axis slide 2 and the components on the Y-axis slide 2 to move closer to the chuck, and then directly cuts the remaining pipe, thereby reducing the amount of tail material.

[0024] Compared with the prior art, the bevel cutting mechanism provided by the present utility model enables the laser cutting head 71 on the Y-axis slide 2 to move back and forth through the Y-axis driving mechanism 3, breaking the limitation that the traditional laser cutting mechanism is fixed on the gantry beam, thereby increasing the freedom degree of the cutting path, enabling the cutting mechanism to more flexibly adapt to pipes of different lengths and shapes, reducing the generation of tail material, and reducing material waste. In addition, the bevel cutting mechanism replaces the traditional gantry beam type cutting mechanism, reducing the overall height of the laser pipe cutting machine, not only simplifying the transportation and installation process of the equipment, but also saving the space in the factory workshop, which is beneficial to optimizing the production layout and improving the space utilization rate.

[0025] In one embodiment, the vertical plate 12 of the T-shaped frame 1 is slidably arranged at the front end of the bed of the laser cutting machine through a Z-axis guide rail 13 and a Z-axis slider 14. Through the precise cooperation of the Z-axis guide rail 13 and the Z-axis slider 14, the movement of the components on the T-shaped frame 1 in the vertical direction is more stable and accurate. Since the bevel cutting mechanism is installed by means of the bed of the laser cutting machine, not only the manufacturing cost can be saved, but also the overall volume of the equipment is greatly reduced, and the space utilization efficiency is improved.

[0026] Furthermore, the Z-axis driving mechanism 8 includes a Z-axis driving motor 81 fixed on the vertical plate 12, a first gear 82 arranged at the output end of the Z-axis driving motor 81, and a Z-axis rack 83 vertically fixed on the bed of the laser cutting machine. The first gear 82 meshes with the Z-axis rack 83 for transmission. Compared with other transmission methods, the transmission of the grinding-level first gear 82 and the Z-axis rack 83 realizes the high-precision and rapid lifting movement of the T-shaped frame 1, which can ensure the cutting quality.

[0027] In another embodiment, the bevel cutting mechanism further includes a chassis fixed to the ground. The vertical plate 12 of the T-shaped frame 1 is slidably arranged on the chassis through a Z-axis guide rail 13 and a Z-axis slider 14. By such an arrangement, the bevel cutting mechanism forms an independent module with good stability. The chassis can be flexibly arranged according to the actual site conditions, without being restricted by the size and shape of the bed body, which is beneficial to the effective utilization of space and the reasonable planning of the production process.

[0028] Furthermore, the Z-axis driving mechanism 8 includes a Z-axis driving motor 81 fixed to the vertical plate 12, a first gear 82 arranged at the output end of the Z-axis driving motor 81, and a Z-axis rack 83 vertically fixed to the chassis. The first gear 82 meshes with the Z-axis rack 83 for transmission. Compared with other transmission methods, the transmission between the precision-ground first gear 82 and the Z-axis rack 83 realizes the high-precision and rapid lifting movement of the T-shaped frame 1, which can ensure the cutting quality.

[0029] Specifically, the Y-axis slide 2 is slidably arranged on the flat plate 11 through a Y-axis guide rail 15 and a Y-axis slider 16. The Y-axis driving mechanism 3 includes a cylinder bracket 31 fixed to the T-shaped frame 1, a cylinder 32 arranged on the cylinder bracket 31, and a transmission plate 33 arranged at the bottom of the Y-axis slide 2. The end of the piston rod of the cylinder 32 is drivingly connected to the transmission plate 33. The telescopic movement of the piston rod of the cylinder 32 can enable the laser cutting head 71 to quickly move and switch between the normal cutting station and the tailstock cutting station, with accurate positioning, which can significantly improve the working efficiency and processing accuracy.

[0030] Furthermore, the X-axis slide 4 is slidably arranged on the Y-axis slide 2 through an X-axis guide rail 17 and an X-axis slider 18. The X-axis driving mechanism 5 includes an X-axis driving motor fixed to the X-axis slide 4, a second gear (invisible in the figure) arranged at the output end of the X-axis driving motor, and an X-axis rack (invisible in the figure) extending left and right on the Y-axis slide 2. The second gear meshes with the X-axis rack for transmission. The transmission between the precision-ground second gear and the X-axis rack ensures that the movement of the laser cutting head 71 in the left-right direction has extremely high positioning accuracy, ensuring fine cutting and bevel cutting quality.

[0031] Preferably, dust-proof covers 91 for covering the Y-axis guide rail 15 are provided on the front and rear sides of the Y-axis slide 2. The dust-proof covers 91 can effectively block dust, chips and other impurities from entering between the Y-axis guide rail 15 and the slider, reduce the wear of these particles on the guide rail and the slider, and avoid movement blockage and accuracy decline caused by foreign object intrusion, thereby improving the reliability and cutting accuracy of the equipment.

[0032] Preferably, a side panel 92 for covering the X-axis guide rail 17 and the X-axis slider 18 is provided on the X-axis slider 4. The side panel 92 can effectively prevent external dust, chips and other impurities from invading the area of the X-axis guide rail 17 and the X-axis slider 18, reduce the wear and corrosion of these particles on the guide rail and the slider, maintain the smoothness of the guide rail and the normal operation of the slider, thereby improving the reliability and cutting accuracy of the equipment.

[0033] To improve the structural strength of the T-shaped frame 1, the connection between the flat plate 11 and the vertical plate 12 of the T-shaped frame 1 is reinforced by multiple gusset plates 93. By using multiple gusset plates 93 at the connection between the flat plate 11 and the vertical plate 12 of the T-shaped frame 1, the structural strength of the connection part is significantly improved, reducing structural deformation and fatigue damage caused by heavy load or high-frequency vibration, and enhancing the stability and durability of the entire frame. Vertical side plates 94 are provided on both sides of the vertical plate 12. The vertical side plates 94 not only increase the lateral rigidity of the T-shaped frame 1, but also provide additional support for the components installed on the vertical plate 12, reducing swing and vibration during equipment operation and improving the overall stability of the equipment.

[0034] To ensure continuous and sufficient lubrication of the rack and the gear, reduce the transmission resistance, and ensure the movement accuracy of the laser pipe cutting head, a first lubricating wheel 95 in lubricating contact with the Z-axis rack 83 is provided on the vertical plate 12, and a second lubricating wheel in lubricating contact with the X-axis rack is provided on the X-axis slider 4. The oil supply pump 97 pumps lubricating oil to the first lubricating wheel 95 and the second lubricating wheel through the lubricating oil pump.
