Investigation on the influence of mandrel on the forming quality of thin-walled tube during free bending process

Cheng Cheng et al.

Summary: This study analyzed the influence of inserting a mandrel inside the thin-walled tube during free bending process, including the mandrel position, number of core balls, and clearance between mandrel and tube. The numerical simulation method was used to verify the reliability and rationality of the mandrel parameters, advancing understanding on deformation behavior and improving forming quality in thin-walled tubes.

Granular media filler assisted push bending method of thin-walled tubes with small bending radius

Hong-wu Song et al.

Summary: This study presents a new push bending method using granular media filler for manufacturing thin-walled tubes with small relative bending radius. By investigating the pressure distribution of the granular system, the method strengthens the bending deformation of the tubes, effectively preventing the formation of defects such as wrinkles.
