[0024] The utility model provides a device for adjusting the curvature of a pipe material for a vehicle frame.
[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including an operating table 1, a carrying plate 2 is fixedly connected to the top of the carrying plate 2, a connecting plate 3 is fixedly connected to the top of the connecting plate 3, a shell 4 is fixedly connected to the top of the connecting plate 3, a motor 5 is installed inside the shell 4, a threaded rod 6 is fixedly connected to the output end of the motor 5, the threaded rod 6 is rotatably connected to the top of the operating table 1, the threaded rod 6 is rotatably connected to the inside of the connecting plate 3, a slider 7 is threadedly connected to the outside of the threaded rod 6, a balancing block 8 is fixedly connected to both sides of the slider 7, a sliding rod 9 is slidably connected to the inside of the balancing block 8, and the bottom of the sliding rod 9 is fixedly connected to the top of the operating table 1, a sliding groove 10 is opened on the carrying plate 2, a telescopic rod 11 is fixedly connected to the bottom of the connecting plate 3, a connecting block 12 is fixedly connected to the bottom of the telescopic rod 11, a roller 13 is fixedly connected between the connecting block 12 and the slider 7, and the outside of the slider 7 is slidably connected to the inner wall of the sliding groove 10.
[0026] Working principle: when the curvature of the pipe material needs to be adjusted, first start the motor 5 to drive the threaded rod 6 to rotate forward. When the threaded rod 6 rotates forward, the slider 7 threadedly connected to the threaded rod 6 moves downward with the rotation of the threaded rod 6. The slider 7 passes through the bearing plate 2 and is connected to the roller 13. The roller 13 moves downward with the slider 7. When the roller 13 moves downward, it drives the connecting block 12 connected to the roller 13 to move downward. One end of the telescopic rod 11 is connected to the bottom of the connecting plate 3, and the other end of the telescopic rod 11 is connected to the top of the connecting block 12. When the connecting block 12 moves downward, the telescopic rod 11 will be stretched, which will not affect the movement of the roller 13 while keeping the roller 13 balanced.
[0027] The rotation of the threaded rod 6 drives the slider 7 downward, and at the same time drives the balancing blocks 8 connected to both sides of the shell 4 to move downward. The balancing blocks 8 are slidably connected to the outside of the slide rod 9, which facilitates the movement of the balancing blocks 8 and increases the stability of the slider 7 to prevent instability when the motor 5 drives the threaded rod 6 to rotate. When the roller 13 squeezes the pipe material downward, the lower the position of the roller 13, the greater the curvature of the pipe material.
[0028] The reverse start motor 5 drives the threaded rod 6 to rotate in the reverse direction. When the threaded rod 6 rotates in the reverse direction, the slider 7 connected to the threaded rod 6 moves upward. When the slider 7 moves upward, the roller 13 moves upward. When the roller 13 moves upward, the connecting block 12 connected to the roller 13 moves upward. When the connecting block 12 moves upward, the telescopic rod 11 is retracted to keep the movement of the roller 13 balanced. When the slider 7 moves upward, the balancing blocks 8 connected to both sides are moved. The balancing blocks 8 still slide outside the slide bar 9 to maintain stability. The higher the position of the roller 13, the smaller the curvature of the pipe material.
[0029] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4, both sides of the front end of the bearing plate 2 are rotatably connected with a rotating shaft 14, the outer part of the rotating shaft 14 is slidably connected with an arc-shaped baffle plate 15, and the outer part of the rotating shaft 14 is fixedly connected with an arc-shaped baffle plate 2 16. The rear end of the arc-shaped baffle plate 15 is fixedly connected with a fixing block 17, and the top of the fixing block 17 is threadedly connected with a bolt 18. The rotating shaft 14 is provided with a plurality of thread grooves 19, and the bolts 18 are threadedly connected with the thread grooves 19. The front end of the arc-shaped baffle plate 15 is fixedly connected with a plurality of limiting rods 20, and the arc-shaped baffle plate 2 16 is provided with a plurality of movable grooves 21. The front end of the rotating shaft 14 is fixedly connected with a limiting plate 22, and the outer part of the rotating shaft 14 is rotatably connected with a support plate 23, and the four corners of the bottom of the operating table 1 are fixedly connected with support columns 24. The limiting rod 20 is slidably connected to the inner wall of the movable groove 21, and the support plate 23 is fixedly connected to the top of the operating table 1.
[0030] When the equipment is required to adapt to pipes of the same thickness, firstly, the bolt 18 is rotated to make the bolt 18 leave the thread groove 19, and then the arc baffle 15 is pushed forward. When the arc baffle 15 is pushed, the fixed block 17 connected to the arc baffle 15 is driven to move forward. When the fixed block 17 moves forward, the bolt 18 connected to the fixed block 17 is driven forward. When the arc baffle 15 moves to the ideal position, the bolt 18 is aligned with the thread groove 19, and then the bolt 18 is rotated to make the bolt 18 enter the thread groove 19 to fix the arc baffle 15. When the arc baffle 15 is pushed forward, the limit rod 20 is driven to slide in the movable groove 21. The limit rod 20 is used to maintain the connection between the arc baffle 15 and the arc baffle 2 16 and maintain the stability of the arc baffle 15. A limit plate is arranged at the front end of the limit rod 20 to prevent the limit rod 20 from falling and affecting the connection between the arc baffle 15 and the arc baffle 2 16.
[0031] The rotating shaft 14 passes through the support plate 23 and is rotatably connected inside the support plate 23, which can increase the balance and stability of the rotating shaft 14. At the same time, a limit plate 22 is fixedly connected to the front end of the rotating shaft 14, and the limit plate 22 can limit the rotating shaft 14 to prevent the rotating shaft 14 from separating from the support plate 23. The four corners of the bottom of the operating table 1 are fixedly connected with support columns 24 to increase the stability of the entire device.
