Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 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 shall fall within the protection scope of the present utility model.

[0026] As Figures 1-4 shown, a technical solution provided by the present utility model:

[0027] A pipe bender includes a body 1. A platform 2 is provided at the top of the body 1. On one side of the platform 2, transmission cases 3 are symmetrically arranged. A driving mechanism is provided inside the transmission cases 3. The driving mechanism includes a driving roller assembly 5. The driving roller assembly 5 is arranged inside the transmission case 3. A number of push rod motors 6 are arranged side by side outside the transmission case 3. The output shaft of the push rod motor 6 is connected to the driving roller assembly 5. A sliding table 4 is movably installed on the side of the platform 2 away from the transmission case 3. A fixed roller 11 is provided at the top of the sliding table 4. A translation mechanism is provided between the sliding table 4 and the platform 2. The translation mechanism includes a first motor 7. The first motor 7 is arranged on the side of the platform 2 close to the sliding table 4. A lead screw 8 is provided below the platform 2 close to the sliding table 4. The output shaft of the first motor 7 is fixedly connected to the lead screw 8. A movable block 9 threadedly connected to the lead screw 8 is provided in the middle of the bottom end of the sliding table 4. A protection mechanism is provided at the top of the left transmission case 3. The protection mechanism includes a bracket 10. The bracket 10 is arranged on the side of the left transmission case 3 close to the fixed roller 11. Below the other side of the bracket 10, a hanger 12 is provided. Stop bars 13 are provided on both sides below the hanger 12. A second motor 18 is provided inside the left transmission case 3 close to the lower part of the bracket 10. The output shaft of the second motor 18 is fixedly connected to the bracket 10;

[0028] In this embodiment, during protection, the motor 2 18 is started. After the motor 2 18 is started, the bracket 10 is controlled to flip. After the bracket 10 flips, it drives the two blocking rods 13 to abut against the two sides of the pipe end. When the pipe is bent again, the motor 2 18 drives the bracket 10 to rotate synchronously, and then the blocking rod 13 and the pipe can be controlled to move simultaneously. At this time, the first part of the pipe that is bent remains parallel to the transmission housing 3. In this way, when bending, this part of the pipe is blocked by the blocking rod 13 and will not pop out to the outside to hurt people.

[0029] like Figure 3 As shown, the inner ends of the hanger 12 are further provided with a shock absorbing mechanism, which includes a spring damper 14, which is symmetrically arranged at the inner ends of the hanger 12, and the output end of the spring damper 14 is fixedly connected with a mounting seat 15, and the blocking rod 13 is fixedly connected to the bottom end of the mounting seat 15. A guide rod 16 is transversely arranged at the inner upper end of the hanger 12, and a movable sleeve 17 movably connected to the guide rod 16 is arranged at the top end of the mounting seat 15;

[0030] In this embodiment, since a mounting seat 15 is installed inside the hanger 12 through a spring damper 14, and the mounting seat 15 is connected to the baffle rod 13 at the bottom, when the baffle rod 13 flips over to clamp the pipe, the baffle rod 13 and the spring damper 14 can cooperate to open to both sides, so that it is convenient for the baffle rod 13 to move to the outside of the pipe. At the same time, since the spring damper 14 is provided, the vibration generated when the pipe breaks can also be reduced by the spring damper 14.

[0031] Working principle: when bending, the pipe is pushed in from the left side of the transmission housing 3, and the driving roller assembly 5 is controlled by the push rod motor 6 to clamp the pipe, and then the driving roller assembly 5 is used to push the pipe to one side of the fixed roller 11. When the end of the pipe passes a part from the outside of the fixed roller 11, the motor 1 7 is started. After the motor 1 7 is started, the screw rod 8 is driven to rotate, and the screw rod 8 drives the slide 4 to move forward through the movable block 9. When the slide 4 moves, the protruding part of the pipe is bent through the fixed roller 11, and then the motor 2 18 is started. After the motor 2 18 is started, the bracket 10 is controlled to flip. After the bracket 10 flips, it drives the two baffles 13 to abut on both sides of the end of the pipe. When the pipe is bent again, the motor 2 18 drives the bracket 10 to rotate synchronously, and then the baffle 13 can be controlled to move simultaneously with the pipe. At this time, the first part of the pipe that is bent remains parallel to the transmission housing 3, so that when bending, this part of the pipe is blocked by the baffle 13 and will not pop out to the outside to hurt people.

[0032] The above has shown and described the basic principles, main features and advantages of the present utility model.
