Detailed Description of the Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0024] As shown in the attached Figures 1 to 3A high-precision automatic pipe bender shown in the figure includes a workbench 1. On one side of the upper surface of the workbench 1, a movable plate 2 is embedded. On one side of the movable plate 2, a driving member 201 is provided. The output end of the driving member 201 is connected to the movable plate 2. On both sides of the top of the movable plate 2, limiting rings 3 are provided. In the middle of the two groups of limiting rings 3, a feeding pipe 4 is provided. Along the outer wall of the middle part of the feeding pipe 4, connecting rods 5 are arranged in an embedded manner. One end of the connecting rod 5 is connected to an arc-shaped clamping plate 6. The end of the connecting rod 5 far from the arc-shaped clamping plate 6 passes through the feeding pipe 4 and is movably connected to a pressing rod 7 through a rotating shaft. The end of the pressing rod 7 far from the connecting rod 5 is movably connected to the outer wall of the feeding pipe 4 through a rotating shaft. A first spring 8 is arranged between the pressing rod 7 and the middle of the feeding pipe 4. On the side of the pressing rod 7 far from the connecting rod 5, a moving ring 9 is provided. On the outer wall of one side of the feeding pipe 4, an electric telescopic rod 10 is provided. The telescopic end of the electric telescopic rod 10 is connected to the moving ring 9. On the outer wall of one end of one side of the feeding pipe 4, a driven gear 11 is key-connected. On one side of the top of the movable plate 2, a servo motor 12 is connected. The output end of the servo motor 12 is connected to a driving gear 13. The driving gear 13 meshes with the driven gear 11.

[0025] Among them: Insert the pipe into the feeding pipe 4. The electric telescopic rod 10 can be used to push the moving ring 9 to perform a translational movement. The moving ring 9 moves translationally and thus sleeves outside the pressing rod 7 to squeeze one end of the pressing rod 7. The pressed pressing rod 7 rotates to push the connecting rod 5 to translate towards the inner wall of the feeding pipe 4. The connecting rod 5 pushes the arc-shaped clamping plate 6 to clamp and fix the pipe. The arc-shaped clamping plate 6 can clamp and fix pipes with different diameters. After clamping, the feeding pipe 4 and the pipe can be pushed by the driving member 201 to translate to realize the pipe feeding work for pipe bending. When the pipe bending angle needs to be adjusted, the servo motor 12 can be used to drive the driving gear 13 to rotate. The driving gear 13 drives the driven gear 11 to rotate, so that the feeding pipe rotates along the limiting ring 3 to facilitate the adjustment of the pipe bending angle, thereby replacing manual rotation of the angle to improve the pipe bending accuracy. Embodiment

[0026] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, see the following description for details:

[0027] As a preferred implementation method, a fixed seat 14 is connected to one side of the workbench 1. The middle of the fixed seat 14 is connected to a central shaft 15 through a bearing. A pipe bending die 16 is sleeved in the middle of the central shaft 15; further, the central shaft 15 can be driven by a motor to rotate, and the pipe bending die 16 is arc-shaped to facilitate the bending treatment of the pipe.

[0028] As a preferred embodiment, a connecting frame 17 is key-connected to the outer wall of the middle part of the central shaft 15, and telescopic cylinders 18 are arranged on the side of the connecting frame 17 close to the workbench 1; further, the connecting frame 17 plays a connecting role, and the central shaft 15 can be driven by a motor to rotate, thereby driving the connecting frame 17 to rotate, so as to bend the clamped pipe.

[0029] As a preferred embodiment, the telescopic end of the telescopic cylinder 18 is connected with a connecting seat 19, and a limiting groove 20 is arranged on one side of the connecting seat 19; further, the connecting seat 19 plays a connecting role, and the telescopic cylinder 18 can push the connecting seat 19 to move horizontally, thereby driving the clamping block 21 to cooperate with the pipe bending die 16 for pipe bending.

[0030] As a preferred embodiment, a clamping block 21 is arranged on one side of the connecting seat 19, the two clamping blocks 21 correspond to the pipe bending die 16, one end of the clamping block 21 is connected with a limiting block 22, and the limiting block 22 is embedded in the limiting groove 20; further, the clamping block 21 plays a role in clamping and fixing, and the limiting block 22 plays a role in limiting.

[0031] As a preferred embodiment, a clamping groove 23 is arranged on the top of the limiting block 22, a clamping block 24 is embedded at the top of the limiting groove 20, and the bottom end of the clamping block 24 is embedded in the clamping groove 23; further, the clamping block 24 and the clamping groove 23 play a role in fixing and limiting.

[0032] As a preferred embodiment, a connecting rod 26 is arranged on the top of the clamping block 24, and a second spring 25 is sleeved on the outer wall of the connecting rod 26; further, the connecting rod 26 plays a connecting role, and the second spring 25 is compressed, contracted and rebounds.

[0033] As a preferred embodiment, the end of the connecting rod 26 far away from the clamping block 24 passes through the connecting seat 19 and is connected with a pulling block 27; further, pulling the pulling block 27 can drive the connecting rod 26 to move upward horizontally, and the horizontal movement of the connecting rod 26 drives the clamping block 24 to move upward horizontally, so as to move out of the clamping groove 23, so as to facilitate taking out the clamping block 21 for replacement of different calibers, so as to be able to carry out pipe bending work for pipes of different diameters.

[0034] The working process of the present utility model is as follows: When it is necessary to bend the pipe, the pipe can be inserted into the feeding pipe 4. The electric telescopic rod 10 can be used to push the moving ring 9 to perform a translational movement. The translational movement of the moving ring 9 causes it to sleeved outside the pressure rod 7, thereby squeezing one end of the pressure rod 7. The pressure rod 7 rotates under pressure and pushes the connecting rod 5 to translate towards the inner wall of the feeding pipe 4. The connecting rod 5 pushes the arc-shaped clamping plate 6 to clamp and fix the pipe. The arc-shaped clamping plate 6 can clamp and fix pipes with different diameters. After clamping, the driving member 201 can be used to push the feeding pipe 4 and the pipe to translate, thereby realizing the feeding work for pipe bending. When it is necessary to adjust the pipe bending angle, the servo motor 12 can be used to drive the driving gear 13 to rotate. The driving gear 13 drives the driven gear 11 to rotate, so that the feeding pipe rotates along the limiting ring 3 to facilitate the adjustment of the pipe bending angle. The telescopic cylinder 18 can be used to push the connecting seat 19 to translate, thereby driving the clamping block 21 to cooperate with the pipe bending die 16 to perform the pipe bending process. Pulling the pulling block 27 can drive the connecting rod 26 to translate upward. The translational movement of the connecting rod 26 drives the clamping block 24 to translate upward and thus move out of the clamping groove 23, so as to facilitate the removal of the clamping block 21 for replacement of different calibers, so as to be able to perform the pipe bending work for pipes with different diameters. The above is the working principle of this high-precision automatic pipe bender.

[0035] Finally, the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
