Abstract:In order to improve the rolling efficiency of the cylinder barrel, the rolling machine of the cylinder was designed. It was horizontal structure. And it was composed of frame, worktable, cylinder rolling device and automatic feeding device. Worktable and feeding device were mounted on the frame, the cylinder rolling device was arranged in the worktable. The cylinder barrel was supported by two V blocks on the sliding table. For cylinders with different diameter and length, different varieties production demands were met by replacing and adjusting the axial distance of 2 groups of V blocks. The device has certain flexibility, widely used in rolling in outer surface of cylinder parts; and the production process is automatic and production efficiency is improved.
