Description

Technical Field

[0001] The utility model relates to the technical field of pipe bender, in particular to a pipe bending device for bending a threading pipe. Background Art

[0002] Pipes are widely used in industrial production. According to the design and layout requirements, many pipes are prepared into curved shapes. Pipe bending is a process in which the pipe is plastically deformed by external force to form a certain angle. Pipe bending can achieve various complex shapes and structures to meet different design and functional requirements. There are many ways to bend pipes. Pipes of different materials have different mechanical properties, such as strength and plasticity. These factors will affect the bending effect and difficulty. Pipe bending is a highly technical process. It is necessary to select appropriate bending methods and equipment according to specific materials, sizes and requirements, and continuously optimize process parameters in actual operation to ensure bending quality and efficiency.

[0003] In the prior art, pipe benders are commonly used to bend straight pipes. Pipe benders include manual pipe benders and automatic pipe benders. Among them, manual pipe benders can generally only bend to form fixed angles and cannot meet the needs of multi-angle bending, resulting in a reduced scope of application of the pipe bender. If multiple pipe benders with different angles are used, processing costs will be wasted and work efficiency will be greatly reduced. Automatic pipe benders are usually equipped with electrical components such as a main controller and a detection module. At the same time, the design of control methods and circuits is involved, resulting in a complex structure and increased costs. Utility Model Content
