The appearance and process characteristics of pipe bender ar

The appearance and process characteristics of pipe bender are introduced  

The bending machine produced by our company can bend the pipe as well as the sheet.  In the case of pure bending, when the pipe with outer diameter D and wall thickness 3-120mm is bent under the action of external moment M, the outer pipe wall of the neutral layer is subjected to tensile stress and the pipe wall becomes thinner.  The tube wall inside the neutral layer becomes thicker under tensile stress.  Moreover, the shape of the cross section changes from round to approximately oval due to the resultant force and action. When the deformation is too large, the outer wall of the pipe will crack, and the inner wall of the pipe will wrinkle.  

The degree of deformation depends on the relative bending radius R/D and the relative thickness t/D.  The smaller R/D and T/D values are, the larger the deformation degree is.  In order to ensure the forming quality of pipe fittings, it is necessary to control the deformation degree within the permitted range. The bending forming of pipe fittings is restricted by the mechanical properties of the material and the bending method, and the use requirements of pipe fittings are also considered.  The forming limit of pipe fittings should include the following contents:  

The large elongation deformation in the outer tensile deformation zone of the neutral layer does not exceed the plastic allowable value of the material and cause rupture.  

In the compression deformation zone inside the neutral layer, the thin-walled structure under the action of tangential compressive stress does not wrinkle due to instability.  

If the pipe has the requirement of ellipticity, control its section distortion;  

Limits on forming that control wall thinning if the pipe has a strength requirement to withstand internal pressure.  

The company mainly produces various types and materials of pipe bending machine, bending machine, tee machine, pipe expanding machine, press, beveling machine, straight seam welding pipe production line and other pipe fitting equipment.  Welcome the customer consultation order!
