Rolling press device of column-shaped workpiece surface with non-circular section profile shape and rolling press method

Abstract

The invention relates to a rolling press device of column-shaped workpiece surface with a non-circular section profile silhouette and rolling press method. The rolling press device comprises a hydraulic system and at least two rolling press head mechanisms, wherein the hydraulic system comprises an oil tank, a hydraulic pump, a safety valve, a reversing valve, a speed regulating valve, an overflowvalve and at least two single-acting hydraulic cylinders, wherein at least two single-action hydraulic cylinders and the column-shaped workpiece with the non-circular section profile silhouette are arranged on special equipment, and at least two rolling press head mechanisms are arranged on at least two single-acting hydraulic cylinders; and the special equipment provides the movement of the single-action hydraulic cylinders and the rotation of the workpiece, and the hydraulic system provides rolling press pressure. According to the device, when rolling press is carried out on the column-shaped workpiece surface with the non-circular section profile silhouette by the rolling press device of column-shaped workpiece surface with the non-circular section profile silhouette, at least two single-acting hydraulic cylinders are moved together, so that each rolling press head mechanism is always rolled on the column-shaped workpiece surface with the non-circular section profile silhouette, and the rolling press pressure of the workpiece applied by each single-acting hydraulic cylinder is ensured to be equal.

Description

technical field [0001] The invention relates to a rolling device and a rolling method for the surface of a cylindrical workpiece with a non-circular cross-sectional profile, belonging to the technical field of rolling processing. Background technique [0002] Many parts often need to be strengthened by surface rolling to improve their comprehensive mechanical properties. At present, most rolling devices can realize the surface rolling strengthening of rotary parts with a circular cross-sectional profile, which is not suitable for non-circular cross-sectional profiles. Columnar workpieces cannot be strengthened by surface rolling, and at the same time, it is impossible to ensure that the rolling force applied to the surface of such parts is basically equal. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a rolling device and rolling method for the surface of a cylindrical workpiece with a non-circular cross-s...
