A Double Ring Roller Rolling Mechanism Driven by Spur Gears

Abstract

The invention discloses a double-ring roller rolling mechanism driven by spur gears, which comprises a ring roller assembly, a frame, a floor seat and a transmission assembly; the ring roller assembly is provided with two groups, which are symmetrically installed in the frame; the frame is arranged on the floor seat above, and is rotatably connected with the bottom plate seat; the transmission assembly is provided with two groups and 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 adopts double-ring roller structure to effectively offset the lateral force and additional moment of the ring roller on the workpiece; it utilizes the coupling to drive the active cylindrical gear, which solves the problem of adjusting the feed rate when the sleeves on the left and right sides of the ring roller bracket rotate around their own rotation center line. The problem of power transmission when entering the angle; through the axial translation of the left and right sleeves of the ring roller bracket, the problem of pressing adjustment is solved; through the rotation of the cylindrical boss on the lower surface of the frame bottom plate, the problem of the deflection of the ring roller is solved.

Description

technical field [0001] The invention relates to the technical field of spinning and rolling forming, in particular to a double-ring roller spinning mechanism driven by a spur gear. 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,...

However, the attitude adjustment function of the traditional spinning method is limited. The skew rolling method can adjust the attitude of the roll, but the structure is complicated.
