The invention provides a rolling former which can quickly produce regular and orderly rhombus, circular arcs and other different patterns by rolling forming on the surfaces of a series of thinner sheet metal parts such as iron sheets, stainless steel sheets, aluminum sheets and copper sheets, without removing materials. The rolling former comprises a rack, a transmission mechanism, an upper left roller, an upper right roller, left and right rubber rollers and an upper and lower roller distance adjusting device, wherein, the lower part of the upper and lower roller distance adjusting device isinstalled on the lower rack; the upper left and right rollers are installed on the upper and lower roller distance adjusting device; sheet metal battens are wound on the external surfaces of the upper left and right rollers respectively; the upper and lower roller distance adjusting device comprises a support bar group; the lower part of the support bar group is installed on the rack; both ends of the left and right rubber rollers are respectively installed on support bars; upper support pipe sleeves are sleeved on the support bars; both ends of the upper left and right rollers are respectively installed on the upper support pipe sleeves. The rolling former can improve the anti-bending strength and exterior effects of the processed sheet metal parts.
