What are the basic conditions for discussing the forming requirements of pipe fittings for pipe bending machines? We are a professional manufacturer of fully bent pipe machines with years of rich experience. To ensure the quality of pipe forming, it is necessary to control the degree of deformation within the allowable range, and the bending forming limit of the pipe depends not only on the mechanical properties and bending methods of the data, but also on the usage requirements of the pipe. The degree of deformation of the pipe during the use of the pipe bending machine depends on the relative bending radius R/D and the relative thickness t/D values. The smaller the R/D and t/D values, the greater the degree of deformation.
The forming limit of pipe fittings for pipe bending machines should include the following contents:
1、 If there is a requirement for ovality in the pipe fittings, manipulating their cross-section may cause distortion;
2、 In the compression deformation zone inside the neutral layer, the thin-walled structure affected by tangential compressive stress will not exceed instability and wrinkle.
3、 If the pipe fittings have strength requirements for accepting internal pressure, control the forming limit of their wall thickness reduction.
4、 The maximum elongation deformation in the tensile deformation zone outside the neutral layer does not exceed the allowable plastic deformation value of the data and breaks;
