Product Details

Pipe bender refers to a machine used to bend steel pipes, and can also be used to bend a jack, which can be roughly divided into CNC bending, hydraulic bending and so on. It is suitable for the laying and construction of pipelines such as electric power construction, railway construction, bridges and ships.


Pipe bending machines can be roughly divided into CNC bending machine tools, hydraulic bending machine tools and so on. It is suitable for pipeline laying and maintenance in power engineering, railway construction, boilers, bridges, ships, furniture, decoration and other industries. It has the characteristics of multiple functions, reasonable structure, and simple operation. This machine tool not only has the function of elbow, but also can use the cylinder as a hydraulic jack. Compared with CNC elbow equipment, it has the characteristics of low price and convenient use. It occupies the leading product position in the domestic elbow market.

The pipe bending machine is the same as the sheet bending machine. When a pipe with an outer diameter d and a wall thickness t is bent under the action of an external moment m under pure bending conditions, the outer pipe wall of the neutral layer is subjected to the tensile stress σ1, and the inner side of the neutral layer where the pipe wall becomes thin The pipe wall is thickened by the tensile stress σ1. In addition, the cross-sectional shape changes from a circle of force F1 and F2 to an elliptical shape. When the deformation is too large, cracks appear on the outer tube wall and wrinkles on the inner tube wall.


The degree of pipeline deformation depends on the relative bending radius and relative thickness of R/D and t/D. The smaller the value of R/D and t/D, the greater the degree of pipeline deformation. In order to ensure the quality of pipe forming, the degree of deformation must be controlled within the allowable range. The limit of pipe bending depends not only on the mechanical properties and bending methods of the material, but also on the requirements of use. The forming limits of piping parts should include the following:


In the tensile deformation zone outside the neutral layer, the tensile deformation does not exceed the allowable value of plasticity of the material, resulting in cracking;


In the compression deformation zone inside the neutral layer, the part of the thin-walled structure that is subjected to tangential compressive stress will not wrinkle due to instability;


If the ellipticity of the pipe fitting is required, control the deformation of the section;


If pipe fittings need to withstand internal pressure strength, control the limit of wall thickness reduction.
