A Parallel Transmission Single Ring Roller Rolling Mechanism

Abstract

The invention discloses a single-ring rolling mechanism with parallel transmission, which comprises a ring-roll assembly, a frame, a floor seat and a transmission assembly; the ring-roll assembly is installed in the frame; the frame is arranged above the floor seat, and Rotational connection; the transmission assembly is fixedly arranged on the frame; the transmission assembly runs through the frame and meshes with the driven cylindrical gear of the ring roller assembly. The invention realizes the adjustment of the three process parameters of the contact rolling between the inner surface of the ring roller and the outer surface of the tubular workpiece; utilizes the coupling to drive the active cylindrical gear, and solves the problem that the sleeves on the left and right sides of the ring roller support revolve around their own center of rotation The problem of power transmission when adjusting the feeding angle due to the rotation of the line; the axial translation of the sleeves on the left and right sides of the ring roller bracket solves the problem of pressing adjustment; the rotation of the cylindrical boss on the lower surface of the frame bottom plate solves the deviation of the ring roller Ask questions.

Description

technical field [0001] The invention relates to the technical field of spinning and rolling forming, in particular to a parallel-driven single-ring rolling rolling mechanism. Background technique [0002] Spinning and rolling are currently the main processing methods for high-end tubular workpieces. Spinning is widely used due to its good surface quality and small deformation force; the skew rolling process can achieve large rolling and provide large force parameters, but the surface quality is poor, and the additional deformation of the workpiece is more obvious. In the traditional wheel spinning machine and cross rolling, the outer surface of the deformed die is in contact with the outer surface of the workpiece, and the contact wrapping angle between the wheel or roller and the blank of the tubular workpiece is small, and longitudinal cracks and cracks are likely to occur. Defects such as obvious ripples appear on the surface. Combining spinning and cross rolling, when ...
