Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a pipe bending machine capable of preventing pipe fittings from deflecting. Background Art

[0002] A pipe bender is a mechanical device specially used for bending metal pipes. By using specific dies and mechanical force, the pipe bender can bend metal pipes into the angles and curvatures required by users to meet the needs of various industrial and daily applications. The pipe bender can precisely control the angle, curvature and length of the bend to ensure that the results of each bend are highly consistent, which is especially important for projects that require a large number of identical or similar pipes.

[0003] For example, Chinese patent CN209736387U discloses an automatic pipe bending machine, including an operating platform, a hydraulic pump and a pipe bending mechanism; the hydraulic pump is driven by a driving motor to move, the output power of the hydraulic pump drives the oil cylinder to move, and the oil cylinder drives the pipe bending mechanism to bend; the pipe to be processed is placed between the first pipe clamp and the second pipe clamp, and the steering seat is used to drive the connecting shaft to flip for bending; the pressure sensor detects the pressure information received by the second pipe clamp during the bending process, and according to the detection result, the control system controls the working efficiency of the driving motor to prevent excessive pressure from causing excessive bending and damaging the pipe.
