DETAILED DESCRIPTION

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model proposes a pipe bending mechanism in a pipe bending machine, including an operating base 1, the upper part of the operating base 1 is rotatably provided with two groups of guide wheels 2 arranged in a mirror image, the upper part of the operating base 1 is fixedly connected to a pipe bending device, and the pipe bending device includes an equipment frame 3 fixedly connected to one side of the upper part of the operating base 1, the upper part of the equipment frame 3 is penetrated by a motor 4, a bending roller 5 is fixedly connected to the output end of the motor 4, and a bending limit frame 6 is fixedly connected to the side wall of the bending roller 5, the bending limit frame 6 is arranged in a U-shaped frame structure that is flipped ninety degrees counterclockwise, and also includes a sliding groove 7 opened on the operating base 1, and a positioning device seat 8 is slidably provided on the sliding groove 7. The processing requirements of different bending pipe lengths can be adapted by adjusting the indentation amount of the positioning device seat 8 on the sliding groove 7.

[0025] like Figure 4 、 5 As shown, a telescopic slot 20 is provided on the positioning device seat 8, and a positioning plate 9 is slidably provided on the telescopic slot 20. The telescopic slot 20 provides corresponding activity space due to angle changes during the pipe bending process; an equipment mounting frame 10 is fixedly connected to one side of the positioning plate 9, and a contact sensing module 11 is fixedly connected to the upper part of the equipment mounting frame 10.

[0026] The positioning plate 9 is provided with a trigger rod 12 that cooperates with the contact sensing module 11. The end of the trigger rod 12 is fixedly connected to a top plate 13 arranged on the other side of the positioning plate 9. The top plate 13 contacts the pipeline, and the pressure pushes the trigger rod 12, and the control signal is generated after contacting the contact sensing module 11; the trigger rod 12 is sleeved with a return spring 14 arranged between the top plate 13 and the positioning plate 9. The return spring 14 serves to avoid erroneous operation caused by contact between the trigger rod 12 and the contact sensing module 11 in a non-pressure state. A tightening spring 15 is fixed to the telescopic slot 20. The tightening spring 15 is arranged perpendicular to the positioning plate 9. If there is insufficient space when the pipeline is bent, the telescopic slot 20 provides a retraction amount, and the tightening spring 15 provides a means of tightening and resetting the positioning plate 9.

[0027] like Figure 2 、 3 As shown, a controller 16 is fixedly connected to the upper part of the equipment frame 3, the contact sensing module 11 is in communication connection with the controller 16, and the controller 16 is electrically connected to the motor 4. When a control signal is generated, the controller 16 controls the motor 4 to work after receiving the signal, driving the bending roller 5 and the bending limit frame 6 to bend.

[0028] like Figure 6As shown, a push rod fixing frame 17 is fixedly connected to the lower part of the operating base 1, and an electric push rod 18 passes through the push rod fixing frame 17. The output end of the electric push rod 18 is fixedly connected to a connecting block 19 fixed to the lower part of the positioning device seat 8; the push rod fixing frame 17 is arranged in a U-shaped frame structure.

[0029] When in use, the user passes the pipe between the two sets of guide wheels 2, and then passes it through the bending limit frame 6 on one side of the bending roller 5. The motor 4 drives the bending roller 5 and the bending limit frame 6 to rotate and bend;

[0030] By controlling the operation of the electric push rod 18, the expansion and contraction of the output end drives the connection block 19 to move, thereby adjusting the sliding position of the positioning device seat 8 on the sliding groove 7. After setting, when the pipe is extended to the specified length and reaches the bending position, the extended position of the pipe will contact the top plate 13, and push the trigger rod 12 forward to contact the contact sensing module 11, generating a control signal, and automatically controlling the motor 4 to work and bend;

[0031] After the angle of the pipe can be adjusted by contacting external equipment, the bending operation can be continued. The positioning equipment seat 8 needs to be adjusted before use. As the angle changes during bending, the position angle of the pipe and the top plate 13 changes. The expansion slot 20 provides a contraction space to avoid the generation of limit affecting the processing and use.

[0032] The above is the entire process of using the bending mechanism in a pipe bending machine.

[0033] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
