Abstract：

For one kind of bend forming of continuing short beeline-part tube,the double layers form bending die was designed.The bending die had a forming model-cavity,and the model-cavity was designed through the tube bending trace and by Pro/E tri-dimension software.The tube form's clamp,abdication and exchanging layers were presented.The universal sphere-head mandril was designed at the same time to guarantee the tube's bending parts to be fully formed and the easy clamp of the tube.Additionally,the guiding die and the defending-crape board were designed synchronously.Noncockling and rip were assured and the forming was steady.The shape was full and there was no drape,nip-injure on the formed tube.
