Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machine feeding, in particular to an automatic pipe bending machine and a feeding device thereof. Background Art

[0002] The pipe is bent using a complete set of bending equipment. The most frequently used bending process is cold bending. Cold bending refers to the use of machines such as cylinders and hydraulic cylinders to apply pressure to the round pipe, so that the round pipe rotates around a cylinder, and then the round pipe is bent into a certain shape by external force. When bending the round pipe, the thrust setting of the cylinder should be determined according to the material and hardness of the bent pipe to prevent the round pipe from breaking during the bending process.

[0003] The radius of the round tube that the pipe bending machine can bend is limited, but the degree of the pipe bending machine can be changed. At the same time, when taking out the round tube after bending, the user needs to rotate the round tube first so that the turning point of the round tube is in a vertical state, so that the round tube will not be stuck by the cylinder and cannot be taken out when it is taken out. The existing pipe bending machine does not use a corresponding mechanism to rotate the round tube, which makes it easy for the user to lose gravity and slip when rotating a longer round tube. At the same time, there is no corresponding object in the middle of the round tube to support it, which makes it easier for the round tube to shift its center of gravity when rotating. At the same time, a round tube can be bent multiple times. When it is bent multiple times, the user needs to rotate it manually multiple times due to the lack of a rotating mechanism. The steps are cumbersome and affect the processing speed of the round tube. In view of the above situation, we propose an automatic pipe bending machine and its feeding device. Utility Model Content

[0054] Working principle:

[0055] When using the automatic pipe bending machine and its feeding device, the user first places the round pipe on the top of the support plate 416, and then rotates the bidirectional screw rod 402 to drive the fixed pipe 401 to move, so that the round pipe can be simply supported but can move forward and backward. Then the user aligns the round pipe with the bottom plate 408, and at the same time allows the inside of the round pipe to wrap the support block 410, and then rotates the worm rod 414 to drive the turbine 413 to rotate, and the turbine 413 drives the bottom plate 408 to rotate, and the rotation of the bottom plate 408 drives the support block 410 to move, so that the outer wall of the support block 410 abuts against the inner wall of the round pipe, so that the position of the round pipe is limited, and then rotates the bidirectional screw rod 402 again, so that the fixed pipe 401 can firmly fix the round pipe, and then starts the machine, so that the driving mechanism 404 drives the round pipe forward. At the same time, the servo motor 206 drives the rotating plate 201 to rotate, and the first cylinder 203, the second cylinder 208 and the third cylinder 211 move in coordination to bend the round tube. After the bending is completed, the user rotates the bidirectional screw rod 402 to allow the round tube to rotate inside the fixed tube 401, and then starts the rotating cylinder 415 to drive the round tube to rotate 180 degrees, so that the bending part is parallel to the workbench 1, and then starts the lifting cylinder to drive the telescopic table 213 to move downward, so that the round tube moves to the bending movable plate 209, and starts the rotating cylinder 415 again to drive the round tube to rotate, so that the bending point of the round tube is in a vertical state, and then starts the driving mechanism 404 to drive the round tube to move, so that the bending part of the round tube moves to a position without obstructions, so that the user can directly take out the round tube;

[0056] When taking out the bent pipe, the user rotates the bidirectional screw rod 402 so that the round pipe can rotate inside the fixed pipe 401, and then starts the rotating cylinder 415 to drive the round pipe to rotate 180 degrees so that the bent pipe is parallel to the workbench 1, and then starts the lifting cylinder to drive the telescopic table 213 to move downward, so that the round pipe moves to the bending movable plate 209, and then starts the rotating cylinder 415 to drive the round pipe to rotate so that the bending point of the round pipe is in a vertical state, and then starts the driving mechanism 404 to drive the round pipe to move so that the bending point of the round pipe moves to a position without obstructions, so that the user can directly take out the round pipe;

[0057] When bending the round tube, the user first places the round tube on the top of the support plate 416, and then rotates the bidirectional screw 402 to drive the fixed tube 401 to move, so that the round tube can be simply supported, but can move forward and backward. Then the user aligns the round tube with the bottom plate 408, and at the same time allows the inside of the round tube to wrap the support block 410, and then rotates the worm 414 to drive the support block 410 to move, so that the outer wall of the support block 410 is against the inner wall of the round tube, so that the position of the round tube is limited, and then rotates the bidirectional screw 402 again, so that the fixed tube 401 can firmly fix the round tube, and then starts the machine, so that the driving mechanism 404 drives the round tube forward, while the servo motor 206 drives the rotating plate 201 to rotate, and the first cylinder 203, the second cylinder 208 and the third cylinder 211 move in coordination to bend the round tube.
