DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0022] Specifically, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、and Figure 5 As shown in, a pipe bending device for processing adjustable tubular metal materials includes a bottom plate 14. A fixed wheel 1 is vertically installed at the center of the upper surface of the bottom plate 14. A moving wheel 2 is installed in parallel on the side of the fixed wheel 1. An adjusting member 5 is sleeved at the upper end between the fixed wheel 1 and the moving wheel 2, and a limiting frame 16 is sleeved at the lower end. A "C"-shaped fixing frame 3 is fixedly installed on the shaft of the moving wheel 2. A handle 4 is welded on the outer side of the fixing frame 3. A circular ring groove 15 is opened on the outer circumference of the bottom plate 14. A blocking rod 11 is movably installed inside the circular ring groove 15. A fixing device is provided near the sides of the fixed wheel 1 and the moving wheel 2. The fixing device includes a fixed blocking block 6. The fixed blocking block 6 is fixedly installed on the top surface of a sliding block 9. A slider locking rod 10 is provided on the side of the sliding block 9. The sliding block 9 is slidably installed on a slide rail 8. Both ends of the slide rail 8 are fixedly connected to slide rail fixing members 7. The slide rail fixing members 7 are fixedly installed on the bottom plate 14. When in use, the pipe to be bent passes through between the fixed wheel 1 and the moving wheel 2. Since the sliding block 9 is slidably installed on the slide rail 8, the fixed blocking block 6 fixedly installed on the top surface of the sliding block 9 can be driven to move by sliding the sliding block 9, so that it abuts against the pipe wall of the pipe to be bent. When the pipe diameter is different, the pipe can be fixed as a blocking block by sliding adjustment, so that the pipe can be stably bent. After determining the position of the sliding block 9, the slider locking rod 10 can be rotated to fix the sliding block 9. After the pipe is placed, the handle 4 is pushed towards the fixed wheel 1. Since the handle 4 is fixedly connected to the fixing frame 3 and the fixing frame 3 is fixed on the shaft of the moving wheel 2, and the fixed wheel 1 is fixedly installed on the bottom plate 14, during the pushing process, the fixing frame 3 fixedly connected to the handle 4 drives the moving wheel 2 to rotate around the fixed wheel 1, and a pressure can be applied to the pipe fixed between the fixed wheel 1 and the moving wheel 2, and the pipe will be bent around the fixed wheel 1.

[0023] Specifically, please refer to Figure 5As shown, the lower end of the shaft of the moving wheel 2 is fixedly connected to the adjusting slider 18, and the adjusting slider 18 is slidably sleeved on the limiting frame 16. The limiting frame 16 has a sliding groove 17 inside, and the adjusting slider 18 slides in the sliding groove 17. The limiting frame 16 is a shaft with one end suspended and the other end fixedly connected to the fixed wheel 1. The outer side of the adjusting slider 18 is provided with a threaded hole, which is through, and the threaded hole is threadedly connected to the locking screw 19. When in use, when the distance between the fixed wheel 1 and the moving wheel 2 is adjusted, since the limiting frame 16 has a sliding groove 17 inside and the adjusting slider 18 is slidably installed on the limiting frame 16, the moving wheel 2 fixedly connected to the top surface of the adjusting slider 18 will move in the sliding groove 17 of the limiting frame 16 along the adjustment direction, and the parallel movement of the moving wheel 2 can be limited.

[0024] For details, please refer to Figure 3 As shown, the adjusting member 5 includes a fixed rack 51, one end of which is sleeved on the top of the shaft of the fixed wheel 1, the fixed rack 51 is opposite to the rack surface of the movable rack 54, one end of the movable rack 54 is fixed to the top of the shaft of the moving wheel 2, and a positioning slider 55 is slidably sleeved on the fixed rack 51 and the movable rack 54. A tightening screw 56 is threadedly installed on the side of the positioning slider 55 close to the movable rack 54, and an adjusting gear 53 is fixedly installed inside the positioning slider 55. The adjusting gear 53 is meshed with the fixed rack 51 and the adjusting gear 53. The upper surface of the adjusting gear 53 is fixedly connected to the adjusting rod 52. When in use, the adjusting rod 52 is fixedly connected to the adjusting rod 52. At the top of the gear 53, the adjusting gear 53 is meshed with the fixed rack 51 and the movable rack 54, so rotating the adjusting rod 52 can drive the 53 fixedly connected thereto to rotate, and the rotating adjusting gear 53 will drive the movable rack 54 meshed therewith to move laterally outward. Since one end of the movable rack 54 is fixedly connected to the top of the moving wheel 2, when the movable rack 54 moves, the moving wheel 2 moves accordingly, thereby changing the spacing between the fixed wheel 1 and the moving wheel 2. After determining the spacing to be adjusted, the tightening screw 56 is rotated. Since the tightening screw 56 is threadedly connected to the through hole on the side of the positioning adjustment slider 55, the tightening screw 56 is rotated to move it toward the adjusting gear 53, thereby clamping the adjusting gear 53 for fixation.

[0025] Please refer to Figure 4As shown, the bottom plate 14 is provided with an annular groove 15 on the outer circumference and has angular scales engraved on the surface, and the angular scales take the axis of the fixed wheel 1 as the center of the circle, and a baffle rod 11 is movably installed inside the annular groove 15, and the bottom of the baffle rod 11 is fixedly connected to a baffle rod base 13, and the baffle rod base 13 is located below the annular groove 15, and the baffle rod 11 is threadedly connected to a tightening block 12 near the annular groove 15, and the tightening block 12 is located above the annular groove 15. During use, since the annular groove 15 is provided on the surface of the bottom plate 14, the baffle rod 11 installed in the annular groove 15 can move in the annular groove 15, and a tightening block 12 is spirally installed near the bottom plate 14 of the baffle rod 11. After determining the bending angle, the block 12 is tightened to move it toward the bottom plate 14, and the bottom plate 14 is clamped in cooperation with the baffle rod base 13 to fix the position of the baffle rod 11, and the surface of the bottom plate 14 is engraved with an angle for accurately locating the angle required for bending.

[0026] Working principle: During use, the pipe to be bent passes between the fixed wheel 1 and the moving wheel 2, and the adjusting rod 52 can drive the adjusting gear 53 fixedly connected thereto to rotate. The rotating adjusting gear 53 will drive the moving rack 54 meshing therewith to transmit horizontally, and the fixed wheel 1 and the moving wheel 2 fixedly connected to one end of the moving rack 54 will move accordingly to change the spacing. After the spacing between the fixed wheel 1 and the moving wheel 2 is the same as the pipe diameter, since the sliding block 9 is slidably installed on the slide rail 8, the fixed stopper 6 fixedly installed on the top surface of the sliding block 9 can be driven by the sliding sliding block 9 to move so that it is close to the pipe wall of the pipe to be bent. After determining the fixed position, the slider lock rod 10 is rotated to lock and fix it, which can be used as a stopper to fix the pipe. After the pipe is fixed, it is moved and installed The baffle rod 11 in the annular groove 15 determines the bending angle of the pipe fitting. Since the tightening block 12 is spirally installed at the bottom of the baffle rod 11, the tightening block 12 is rotated to move it closer to the bottom plate 14, and the bottom plate 14 is clamped in cooperation with the baffle rod base 13 to fix the position of the baffle rod 11. After determining the bending angle, hold the handle 4 and push it in the direction of the fixed wheel 1. Since the handle 4 is fixedly connected to the fixing frame 3 and the fixing frame 3 is fixedly installed on the axis of the moving wheel 2, and the fixed wheel 1 is fixedly installed on the bottom plate 14, during the pushing process, the handle 4 fixedly connected to the fixing frame 3 drives the moving wheel 2 to rotate around the fixed wheel 1, which can apply pressure to the pipe fitting fixed between the fixed wheel 1 and the moving wheel 2. The pipe fitting bends around the fixed wheel 1 and is clamped at the baffle rod 11 to limit the bending angle.

[0027] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
