Description

Steel pipe bending device

Technical Field

The utility model belongs to the technical field of steel pipe processing equipment and relates to a steel pipe bending device.

Background Art

With the rapid development of modern science and technology, pipe bending technology has been widely used in various production industries, especially in the fields of boilers, pressure vessels, petroleum and petrochemical engineering. With the widespread use of various bent pipes in industry, agriculture and other aspects, the development of the pipe bending machine industry has been continuously promoted. The emergence of a variety of pipe bending technologies has made it possible to meet today's multi-demand, high-precision pipe products, especially in boiler manufacturing, automobiles, aerospace, petroleum and petrochemical engineering and other industries, and is widely used.

When bending steel pipes, most hydraulic pipe bending machines on the market currently have poor fixing effects and are not convenient for moving round pipes. They can only bend the workpiece at a fixed angle, and are prone to problems such as severe flattening of the arc, cracking on the outside of the arc, wrinkling on the inside of the arc, and bending rebound. At the same time, the bending accuracy of the steel pipe is not high, and the bending angle cannot be accurately located, making it difficult to process parts with high precision requirements.

Therefore, we designed a device that is convenient for moving the position of the steel pipe, saving time and effort, and convenient for bending the pipe into different arcs. It can improve the speed and effect of steel pipe bending, while avoiding deformation of the inner side of the steel pipe due to excessive force. At the same time, it can improve the bending accuracy of the round pipe and is suitable for steel pipes of different diameters.
