Description

Technical Field

[0001] This utility model relates to the technical field of pipe bending equipment, specifically a rapid bending equipment for copper pipes used in machine tool assembly. Background Technology

[0002] Machine tool cooling copper pipes, as a key component of the machine tool cooling system, play a crucial role in ensuring machining accuracy, extending tool life, and improving overall operational stability. Machine tool cooling copper pipes typically employ a thin-walled design to reduce weight and lower the load on the machine tool structure while maintaining sufficient strength. The pipe diameter is precisely matched to the machine tool's cooling requirements, ensuring that the coolant flow rate and velocity meet machining requirements. The pipe layout is optimized to minimize bends, reducing coolant flow resistance and ensuring uniform cooling. During installation, the straightness and verticality of the pipes must be ensured to prevent coolant flow obstruction due to installation deviations. Before installation, the copper pipes need to be bent according to the shape of the machine tool to ensure a close fit between the copper pipes and the machine tool surface.

[0003] Existing copper tube bending equipment cannot adjust the bending length of copper tubes in a timely manner during bending. When bending copper tubes at different installation positions on the machine tool, the bending length of the copper tubes needs to be measured, which is inefficient and affects the installation efficiency of the machine tool.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4The copper tube rapid bending equipment for machine tool assembly in this embodiment includes a frame 1. A through hole 3 is provided at the top of the frame 1. A motor 2 is installed at the bottom of the through hole 3. The shaft of the motor 2 extends to the top of the through hole 3. An outer sleeve 4 is fixedly connected to the middle of the shaft of the motor 2. A rotating frame 13 is horizontally fixedly connected to the bottom of the side wall of the outer sleeve 4. A length adjustment mechanism 14 is provided at the top of the rotating frame 13. The length adjustment mechanism 14 includes an adjusting rod 1401. A sliding groove 1402 is provided at the top of the adjusting rod 1401. A linear module 1403 is horizontally arranged inside the adjusting rod 1401. The movable platform is fixedly connected to a movable limiting block 1404, which is slidably connected to a slide groove 1402. A stop block 1405 is fixedly connected to the side of the movable limiting block 1404 away from the outer sleeve 4, and the stop block 1405 is set at a right angle. A semi-support wheel 8 is rotatably connected to the top of the shaft of the motor 2. A boss 5 is horizontally fixedly connected to the top of the side wall of the outer sleeve 4. A movable shaft 6 is vertically fixedly connected to the top of the end of the boss 5 away from the motor 2. A bending wheel 7 is rotatably connected to the top of the movable shaft 6. Bending grooves are opened on the side walls of both the bending wheel 7 and the semi-support wheel 8. The bending wheel 7 and the semi-support wheel 8 are horizontally set. Before bending, the initial position of the adjusting rod 1401 is tangent to the edge of the semi-support wheel 8. At this time, the position of the movable limiting block 1404 is first adjusted according to the required bending length of the copper tube. During adjustment, the movable limiting block 1404 is driven by the linear module 1403 to move along the slide groove 1402 at the top of the adjusting rod 1401 until the tangent distance between the movable limiting block 1404 and the semi-support wheel 8 matches the length of the copper tube to be bent. Then, the straight copper tube is inserted into the bending groove between the bending wheel 7 and the semi-support wheel 8 until the first end of the copper tube moves to the inside of the movable limiting block 1404 and abuts against the stop block 1405. At this time, the movable limiting block... 1404 can limit the radial direction of the copper tube bend and block the axial direction of the bend by the stop block 1405. Then, the motor 2 drives the outer tube 4 to rotate in the direction of the rack 17, so that the boss 5 on the side of the outer tube 4 and the movable shaft 6 start to rotate around the shaft of the motor 2. When the movable shaft 6 moves, it drives the bending wheel 7 to start to rotate around the half support wheel 8, applying radial pressure to the copper tube, so that the copper tube starts to bend around the half support wheel 8. When the outer tube 4 rotates, it drives the rotating frame 13 and the movable limit block 1404 to rotate accordingly, thereby applying pressure to the beginning of the copper tube bend at the same time and limiting it to prevent the copper tube from deviating during bending and improving the bending accuracy.

[0023] A second fixed frame 12 is fixedly connected to the middle of the frame 1, and a second fixed limiting block 18 is fixedly connected to the top of the second fixed frame 12. A first fixed frame 10 is fixedly connected to the top of the frame 1 away from the rotating frame 13, and a first fixed limiting block 11 is fixedly connected to the top of the first fixed frame 10. The first fixed limiting block 11 is located on the side of the bending wheel 7 away from the rotating frame 13. When the copper tube is bent, its rear fixed end is located inside the first fixed limiting block 11 and the second fixed limiting block 18, thereby limiting the fixed end of the copper tube during bending and preventing the fixed end of the copper tube from shaking under pressure during bending.

[0024] A mounting bracket 15 is provided on the side of the first fixed frame 10. A cylinder 16 is horizontally fixedly connected to the top of the mounting bracket 15, and a rack 17 is fixedly connected to the piston rod of the cylinder 16. A gear 9 is fixedly connected to the bottom of the semi-support wheel 8, and the gear 9 meshes with the rack 17. After bending, the motor 2 drives the rotating frame 13 to reset. At this time, the movable limit block 1404 disengages from the copper tube. Then, the rack 17 is driven by the cylinder 16 to move away from the cylinder 16. When the rack 17 moves, it drives the gear 9 that meshes with it to rotate. When the gear 9 rotates, it drives the semi-support wheel 8 to rotate until it disengages from the bending wheel 7. At this time, the copper tube between the semi-support wheel 8 and the bending wheel 7 can be quickly removed, thereby realizing the rapid unloading of the copper tube.

[0025] Working principle: Before bending, the initial position of the adjusting rod 1401 is tangent to the edge of the semi-support wheel 8. At this time, the position of the movable limiting block 1404 is first adjusted according to the required bending length of the copper tube. During adjustment, the movable limiting block 1404 is driven by the linear module 1403 to move along the slide groove 1402 at the top of the adjusting rod 1401 until the tangent distance between the movable limiting block 1404 and the semi-support wheel 8 matches the length of the copper tube to be bent. Then, the straight copper tube is inserted into the bending section. The bending groove between the bending wheel 7 and the semi-supporting wheel 8 extends until the first end of the copper tube moves to the inside of the movable limiting block 1404 and abuts against the stop block 1405. At this time, the movable limiting block 1404 can limit the radial direction of the bent part of the copper tube, and the stop block 1405 can limit and block its axial direction. At this time, the fixed end of the copper tube at the rear is located inside the first fixed limiting block 11 and the second fixed limiting block 18, respectively, thereby limiting the fixed end of the copper tube during bending and preventing the fixed end of the copper tube from being subjected to pressure during bending. The process begins with a shaking motion. Then, the motor 2 drives the outer sleeve 4 to rotate towards the rack 17, causing the boss 5 on the side of the outer sleeve 4 and the movable shaft 6 to rotate around the shaft of the motor 2. When the movable shaft 6 moves, it drives the bending wheel 7 to rotate around the semi-support wheel 8, applying radial pressure to the copper tube and causing the copper tube to bend around the semi-support wheel 8. When the outer sleeve 4 rotates, it drives the rotating frame 13 and the movable limit block 1404 to rotate accordingly, thereby applying pressure to the beginning of the bent part of the copper tube simultaneously and limiting it to prevent the copper tube from deviating during bending and improving bending accuracy. After bending, the motor 2 drives the rotating frame 13 to reset. At this time, the movable limit block 1404 disengages from the copper tube, and then the cylinder 16 drives the rack 17 to move away from the cylinder 16. When the rack 17 moves, it drives the gear 9 that meshes with it to rotate. When the gear 9 rotates, it drives the semi-support wheel 8 to rotate until it disengages from the bending wheel 7. At this time, the copper tube between the semi-support wheel 8 and the bending wheel 7 can be quickly removed, thereby achieving rapid unloading of the copper tube.
