Technical Field

[0002] A pipe bending machine is an industrial device used to bend metal pipes into specific angles. It is widely used in automobile manufacturing, aerospace, construction and decoration and other fields. It applies precise pressure to the pipe through mechanical, hydraulic or CNC drive to achieve bending processing without wrinkles or deformation.

Then, the long cylinder 211 drives the connecting seat 212 to move vertically downwards. When the two clamping rods 214 are positioned on either side of the pipe to be processed, the two short cylinders 215 drive the two clamping rods 214 to move towards each other, thus clamping the pipe. Afterwards, the long cylinder 211 drives the connecting seat 212 to move vertically upwards to reset. At this time, the pipe to be processed will move along with the connecting seat 212. After the connecting seat 212 resets, the servo motor 26 drives the lead screw 27 to rotate counterclockwise. The counterclockwise rotating lead screw 27 will... The T-shaped nut seat 28 drives the lifting assembly, the clamping assembly, and the pipe to be processed to move towards the pipe bending machine pushing device. When the pipe to be processed is aligned with the vertical face of the clamp of the pipe bending machine pushing device, the long cylinder 211 will drive the pipe to be processed to move downward until it is aligned with the center of the clamp. After alignment, the pipe bending machine pushing device will drive the clamp to move forward and clamp the pipe. After the clamp clamps the pipe, the two short cylinders 215 will drive the two clamping rods 214 to move in opposite directions. Then the long cylinder 211 will drive the connecting seat 212 to reset, and the servo motor 26 will drive the lead screw 27 to rotate clockwise until all structures are reset. At this time, the automatic feeding is completed.
