摘要
The machine for pipe bending is esp. for bending thin walled pipes with circular cross sections. The pipe is placed on a rotating die with a radius corresp. to the pipe bend radius. The pipe is pressed against the die by a transporter with semielliptical grooves. The pipe is bent and deformed so that a circular pipe cross section is generated at the bend. The pipe transporter has a replaceable transition piece. The groove cross section varies in the transition piece steplessly from semielliptical shape to semicircular shape corresp. to the circular pipe section. The transition occurs within a region displaced from the initial clamping point corresp. to the required bend length.
