“…The rational matching relationships amongst the parameters in stagger spinning were analyzed and obtained by establishing the objective function and constraints on the basis of optimization design theory. Tests on aluminum LY12 showed a good agreement with the calculated values [2]. Some key problems such as calculated model dispersion, the treatment of boundary conditions and the definition of load pattern, a set of useful solutions in finite element method of tube spinning process had been advanced [3].…”

The stagger spinning process of 1Cr18Ni9 tube was investigated by using finite element method. The metal flow rule around the roller during the tube stagger spinning was analyzed. The influences of wall thickness of the billet on effective stress and spinning force were studied using software Deform. The simulated results indicate that the proper wall thickness of the billet should be 8~15 mm, for the billet with length of 100mm and inner diameter of 200mm.

“…It was found that multi rollers are bene cial to balance the ow forming force, but the change of roller number affects the size of the contact zone and material ow. Xue et al [4] and Shan et al [5] studied the effect of feed ratio and thinning rate on wall thickness deviation through multi-roller ow forming experiments. Lin et al [6] analyzed the effects of roller pro le radius, feed ratio and thinning rate on wall thickness accuracy and inner diameter deviation of cylinder through simulation and experiment.…”

Multi-roller ow forming has the characteristics of multi-directional loading, which can improve the quality and accuracy of spun products. Roller number and parameter arrangement in a roller set will affect the material ow and rib lling in multi-roller ow forming of cylinder with inner ribs. Therefore, in this paper, a nite element model of multi-roller ow forming was established to explore the effects of roller number and parameter arrangement on the material ow and saturation degree of inner ribs of aluminium cylinder with oblique cross ribs. The results show that increasing roller number can promote the material radial ow, leading to improve the saturation degree of inner rib; and that, in a roller set, applying large radius for the front roller and small radius for the subsequent roller is bene cial to rib lling, and the more radial offset amount of the rst roller has, the more su cient material ow into the inner ribs is under constant total thickness reduction. In addition, an aluminum cylinder with cross ribs had been spun successfully, which had good dimensional accuracy and mechanical properties. The approaches can provide process guidance for manufacturing on ow forming of aluminum cylinder with inner ribs.
