DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0022] Embodiment:
[0023] Please refer to Figures 1-4 , a pipe bending pliers for pipe processing, including a pliers body 1. A limiting body 2 is arranged on one side of the pliers body 1, and a moving body 3 is arranged on one side of the limiting body 2. The pipe to be bent is placed between the moving body 3 and the limiting body 2, and the pipe is bent by the mutual approach of the moving body 3 and the limiting body 2. A groove 201 is opened inside the limiting body 2, and an adjusting rod 7 is arranged in the groove 201. The adjusting rod 7 is rotatably connected to the limiting body 2. Two thread segments with opposite spiral directions are arranged on both sides of the adjusting rod 7. A stop rod 8 is threadedly connected to the thread segment, and the stop rod 8 is slidably matched with the groove 201. The two sides of the bend to be made are limited by the arrangement of the stop rod 8, preventing the pipe from shifting during the bending process; wherein the distance between the two stop rods 8 is adjusted by rotating the adjusting rod 7. Under the limiting action of the groove 201 on the stop rod 8 threadedly connected to the adjusting rod 7, when the adjusting rod 7 rotates, the two stop rods 8 will move relative to each other along the adjusting rod 7, so as to adjust the distance between the two stop rods 8 and limit the positions of the two sides of the pipe to be bent, preventing the pipe from shifting during bending.
[0024] Installation rods 4 are respectively arranged on both sides of the moving body 3. The installation rods 4 penetrate through the pliers body 1 and are slidably connected to the pliers body 1. Connecting plates 5 are arranged at the ends of the two installation rods 4. A threaded rod 6 penetrates through the middle of the connecting plate 5. The end of the threaded rod 6 is rotatably connected to the pliers body 1, and the threaded rod 6 is threadedly connected to the connecting plate 5. By rotating the threaded rod 6, the connecting plate 5 moves along the length direction of the threaded rod 6, thereby driving the two installation rods 4 to move relative to the pliers body 1, so that the moving body 3 moves towards the limiting body 2 side to bend the pipe vertically placed between the limiting body 2 and the moving body 3.
[0025] In this application, the moving body 3 is of a semi-circular arc structure, which is convenient for bending pipes. Limiting grooves 301 are opened at both ends of the moving body 3. Through the limiting grooves 301, the outer wall of the pipe to be bent can be further restricted to prevent the pipe from shifting during the bending process.
[0026] In this application, a cushion block 9 is arranged at the end of the stop rod 8 close to the moving body 3 side, and the cushion block 9 is slidably matched with the stop rod 8. The outer wall of the pipe is limited by the contact between the cushion block 9 and the pipe to be bent. The position of the cushion block 9 is adjusted by the sliding fit between the cushion block 9 and the stop rod 8, and corresponding adjustment is made according to the diameter of the pipe, so that the pipe to be processed is fixed more firmly. The inner surface of the cushion block 9 is of an arc structure, which is convenient for fitting the outer wall of the pipe and better for limiting.
[0027] In this application, a chute 801 is formed on the gear lever 8, a fixed rod 10 is connected to the cushion block 9, the fixed rod 10 is in sliding fit with the chute 801, a threaded portion is provided at the outer end of the fixed rod 10, and a nut 13 is sleeved on the threaded portion. The position of the cushion block 9 is adjusted by sliding the fixed rod 10 along the chute 801. After the position of the cushion block 9 is adjusted, the nut 13 is rotated to contact the outer wall of the gear lever 8, so as to fix the position of the cushion block 9.
[0028] In this application, fixing seats 202 are provided at both ends of the limiting body 2, the end of the adjusting rod 7 is rotatably connected to the fixing seat 202, an adjusting handle is provided outside the fixing seat 202 on one side, the adjusting handle is connected to the adjusting rod 7, and the adjusting rod 7 is driven to rotate by rotating the adjusting handle.
[0029] In this application, the non-threaded part of the adjusting rod 7 located outside the groove 201 is in rotational fit with the gear lever 8. When the gear lever 8 moves out of the groove 201, the gear lever 8 can be rotated vertically downward to facilitate the removal of the bent pipe. At the same time, the gear lever 8 can slide axially along the non-threaded part of the adjusting rod 7. A retaining ring 12 is sleeved on the side of the adjusting rod 7 close to the fixing seat 202. A spring 11 is provided between the retaining ring 12 and the fixing seat 202. Both ends of the spring 11 are connected to the retaining ring 12 and the fixing seat 202 respectively. The retaining ring 12 is in clearance fit with the adjusting rod 7. By providing the spring 11 and the retaining ring 12, a certain thrust is applied to the outside of the gear lever 8 to facilitate the limitation of the position of the gear lever 8. At the same time, when the gear lever 8 is adjusted to the horizontal position, the spring 10 is used to push the retaining ring 12, and the retaining ring 12 pushes the gear lever 8 to cooperate with the threaded section of the adjusting rod 7, and then the adjusting rod 7 is rotated to connect the gear lever 8 with the threaded section of the adjusting rod 7.
[0030] Working principle: When the pipe bender is in use, the pipe to be bent is placed between the moving body 3 and the limiting body 2. The pipe to be bent is perpendicular to the axis of the limiting body 2. Then the adjusting handle is rotated to drive the adjusting rod 7 to rotate. When the adjusting rod 7 rotates, the two gear levers 8 will move relative to each other along the adjusting rod 7, so as to adjust the distance between the two gear levers 8. Then the fixed rod 10 is slid along the chute 801 to adjust the position of the cushion block 9. The positions of both sides of the pipe to be bent are restricted by the gear lever 8 and the cushion block 9. Finally, the threaded rod 6 is rotated to make the connecting plate 5 move along the length direction of the threaded rod 6, so as to drive the two mounting rods 4 to move relative to the pliers body 1, and make the moving body 3 move towards the limiting body 2 side to bend the pipe placed between the limiting body 2 and the moving body 3.
