Abstract
Description

[0002] Most of the coal mines in East China are old mines, and they are all looking for resources deep underground. The deep coal resources have poor conditions and many undulating trends. The working faces and machine lanes formed are mostly irregular, showing large inclination angles and many undulations. The belt conveyor body has large undulations, and the traditional straight intermediate frame cannot meet the transition requirements of the body. According to the changes in the inclination angle of the tunnel, it is necessary to manufacture concave and convex arc intermediate frames for slope change point transition. Taking the concave arc intermediate frame as an example, the traditional bending method uses a press to bend the channel steel in sections. Only the local curvature is formed after pressing, and the bending point size is not accurately grasped. The curvature can only be determined by the height difference from the top of the arc to the horizontal plane after bending. In order to be able to evenly bend the curvature of the intermediate frame, the design and manufacture of the intermediate frame bending device came into being.

[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] like Figure 1-Figure 3 As shown, a new type of profile bending machine provided in this embodiment includes a support plate 1, and a working box 2 is fixedly connected to the upper surface of the support plate 1. A transmission shaft 3 and a plurality of rollers 4 are rotatably connected inside the working box 2. There are two rollers 4, and the transmission shaft 3 is located between the two rollers 4. Both ends of the transmission shaft 3 and the plurality of rollers 4 extend to both sides of the working box 2. The outer walls of both ends of the transmission shaft 3 are sleeved with gears 1 9, and the outer walls of both ends of the plurality of rollers 4 are sleeved with gears 2 10. Both sides of the working box 2 are rotatably connected with a plurality of gears 3 11 meshing with the gears 2 10. There are two gears 3 11, and the gears 3 11 correspond to the gears 2 10 one by one. The two gears 3 11 are located between the gears 1 9 and the gears 2 10, and the plurality of gears 3 11 are meshed with the gears 1 9. The gears 2 10 can be driven to rotate by rotating the gear 1 9, thereby driving the gears 3 11 to rotate, and the two gears 3 11 can keep the two gears 2 10 rotating in the same direction.
[0022] Among them, Figure 1-Figure 3 As shown, both ends of the working box 2 near the multiple rollers 4 are provided with slide grooves 5, and the opposite slide grooves 5 are slidably connected with rollers 6 corresponding to the rollers 4. The same roller 6 is slidably installed in the two opposite slide grooves 5, and the roller 6 is located above the roller 4. The roller 6 can be made to slide up and down in the slide groove 5 to adjust the distance between the roller 6 and the roller 4, so as to adapt to channel steels of different thicknesses. At the same time, the roller 6 and the roller 4 can be used to clamp the two ends of the channel steel, so as to facilitate the processing of the channel steel. The working box 2 is located on both sides of the middle of the multiple rollers 4. The two slide grooves 7 are slidably connected with driven wheels 8, and the driven wheel 8 is located between the two rollers 4. By sliding the driven wheel 8 up and down, the pressure of the driven wheel 8 on the channel steel can be continuously adjusted, and the channel steel can be continuously bent by the driven wheel 8.
[0023] Further, such as Figure 1-Figure 3As shown, both ends of the multiple rollers 6 extend to the outside of the working box 2 respectively, and both ends of the multiple rollers 6 are commonly fixedly connected with a U-shaped plate 12. By directly adjusting the position of the U-shaped plate 12, the position of the two rollers 6 can be adjusted, and the two rollers 6 can be kept moving synchronously.
[0024] Among them, Figure 1-Figure 3 As shown, the two slide grooves 7 are internally connected with a U-shaped slide plate 13 for sliding movement. Both ends of the U-shaped slide plate 13 extend to the outside of the working box 2. Both ends of the U-shaped slide plate 13 are fixedly connected with a fixed plate 14 rotatably connected to the driven wheel 8. The driven wheel 8 can be driven to move up and down through the U-shaped slide plate 13 without affecting the normal rotation of the driven wheel 8. One side of the driven wheel 8 is always located on the outside of the U-shaped slide plate 13, so that the driven wheel 8 can better apply pressure to the channel steel. The internal thread of the working box 2 is connected with a screw rod 15, one end of the screw rod 15 is fixedly connected to the upper surface of the U-shaped slide plate 13, and the other end of the screw rod 15 extends to the outside of the U-shaped plate 12. Rotating the screw rod 15 facilitates the U-shaped slide plate 13 to move up and down, and the U-shaped plate 12 moves up and down at the same time. The screw rod 15 extends to the outside of the U-shaped plate 12, so as not to affect the up and down movement of the U-shaped plate 12.
[0025] Among them, Figure 1-Figure 3 As shown, a plurality of telescopic cylinders 16 are fixedly connected to the upper surface of the working box 2, the number of the plurality of telescopic cylinders 16 is two, and the two telescopic cylinders 16 are respectively located on both sides of the screw rod 15, and the output ends of the plurality of telescopic cylinders 16 are fixedly connected to the U-shaped plate 12, so that the U-shaped plate 12 can be pushed up and down by the telescopic cylinders 16, and the two telescopic cylinders 16 always maintain synchronous movement, so that both sides of the U-shaped plate 12 always remain in a stable state.
[0026] Further, such as Figure 1-Figure 3 As shown, the lower bottom surface of the support plate 1 is fixedly connected with an operating table 17, and the upper surface of the operating table 17 is fixedly connected with a stepper motor 18 and a plurality of fixed blocks 19. The plurality of fixed blocks 19 are internally connected with a screw rod 20 that meshes with a gear 9 and rotates together. One end of the screw rod 20 is connected to the output end of the stepper motor 18. The screw rod 20 is driven by the stepper motor 18, and the gear 9 is driven to rotate by the screw rod 20. The stepper motor 18 is adopted to immediately lock the motor when the motor stops, thereby playing a buffering role.
[0027] like Figure 1-Figure 3As shown, the principle of a new type of profile bending machine provided by this embodiment is as follows: start the stepper motor 18 to drive the screw 20 to rotate, so that the gear 1 9 drives the transmission shaft 3 to rotate, drives the gears 3 11 on both sides to rotate, and then drives the two gears 2 10 to rotate in the same direction, so that the two rollers 4 keep rotating in the same direction, start the two telescopic cylinders 16 to drive the U-shaped plate 12 to move up and down, so that the two rollers 6 slide synchronously inside the slide groove 1 5, adjust the distance between the roller 6 and the roller 4, place the channel steel between the roller 6 and the roller 4, drive the channel steel to move through the roller 4, and then drive the U-shaped slide plate 13 to slide in the slide groove 2 7 by rotating the screw rod 15, and continuously apply pressure to the channel steel through the driven wheel 8.
