Description

Technical Field

[0001] The utility model belongs to the technical field of bent pipe forming, and particularly relates to a bent pipe forming device with automatic cutting. Background Art

[0002] Pipe benders are roughly divided into numerical control pipe benders, hydraulic pipe benders, etc., and are applied to pipeline laying and repair in aspects such as electric power construction, highway and railway construction, bridges, ships, etc. At present, when in use, the pipe bender can perform bending operations on pipes, so that the pipes can be better put into use. The cutting device in the bent pipe forming device is a device used to cut pipes during or before / after the pipe bending process. Its main function is to cut the pipes into the required lengths, or perform precise cutting after the pipe bending is completed to ensure that the products meet the design requirements.

[0003] For example, a Chinese utility model patent with the publication number CN218926889U discloses a hydraulic pipe bender with automatic feeding and cutting. By arranging a cutting device between the feeding device and the bending device, when the feeding device conveys the straight pipe to a certain distance, the feeding is stopped, the cylinder is opened to lift the motor and the cutting disc to cut the straight pipe, then the motor and the cutting disc are lowered, and then the feeding continues, which can save the cutting link of the operator, save manpower and material resources for other work, and reduce the production cost.

[0004] However, when this device performs pipe bending work, it is necessary to stop the cutting work. After the cutting work is completed, the cutting assembly needs to be reset. At the same time, during the process of pipe bending work, it is necessary to remove the pipe after the pipe bending work and then restore the bending assembly to the initial state. The pipe bending work and the cutting work are carried out separately, making the operation steps of the device cumbersome and affecting the working efficiency of the device.
