Forming limit process of conical parts in dieless spinning based on spherical roller
摘要
Abstract
In order to study the influence law of main process parameters on forming limit of conical parts in dieless spinning based on spherical roller,the influence of four main process parameters,such as spinning part half-cone angle,feed rate of the spinning roller,initial diameter of the sheet metal and roller radius,on the forming limit of the spinning part was studied through the spinning forming experiment of the conical part with spherical roller.The results show that the decrease of the half-cone angle of the spinning part leads to the increase of the feed of the spinning roller in the axial direction of the sheet material and the increase of the contact area between the sheet material and the spinning part roller.The spinning part is prone to wrinkles or cracking.In addition,the decrease of the half-cone angle of the spinning part will increase the bending degree of the sheet material at the round corner of the mandrel,and the spinning part is prone to crack.The contact area between the sheet and the roller increases with increasing the feed rate of the roller.The spinning part is prone to appear wrinkle.When the feed rate of the roller decreases,the forming time of the roller to the sheet is prolonged,and the spinning part is prone to appear crack.The increase of the initial diameter of the sheet metal increases the time of the tensile stress on the radial direction of the sheet metal,which leads to the cracking of the spinning part at the top fillet.While the decrease of the half-cone angle of the spinning part leads to the increase of the deformation of the sheet metal and the risk of wrinkling of the part flange.The flange of the part is more likely to wrinkle.The radial tensile stress of the sheet metal with a smaller radius is longer in duration during forming,which leads to cracking of spinning parts more easily.The circumferential compressive stress of the sheet metal with a larger radius increases and lasts longer in duration at the end of spinning forming,resulting in the outer edges of the spinning parts being prone to wrinkles.关键词
