Abstract

The invention relates to a spinning and forming device of a cylindrical part with inner strengthening and outer thinning. The spinning and forming device of the cylindrical part with inner strengthening and outer thinning is suitable for manufacturing a cylindrical part with especially big diameter to enable uniformity of wall thickness of a workpiece to be thinned, the manufacturing cost is reduced, and the purpose of efficient forming of cylindrical parts with different diameters is achieved. The spinning and forming device of the cylindrical part with inner strengthening and outer thinning comprises an actuating device, a holding device, a feeding device and working rolls. The working rolls are formed by a main roll, a plurality of auxiliary supporting rolls and a rotating roll. The main roll is supported by a drive variable speed reversing mechanism which is arranged on a tool body and a tail portion supporting seat body and driven to rotate by an actuating device I through the drive variable speed reversing mechanism. A guide rail and a drive shaft are arranged on the tool body, a sliding rail machine is arranged on the drive shaft, and the drive shaft is driven to rotate by an actuating device II to enable the sliding rail machine to move along the guide rail in a right and left mode. A radial feed device is arranged on the sliding rail machine, and the rotating roll is arranged at the top of the radial feed device. The holding device which is used for holding the cylindrical workpiece is arranged on the main roll. Clamping nuts are arranged at two ends of the holding device. The inner wall of the cylindrical workpiece is attached to the main roll, and the cylindrical workpiece rotates as the main roll rotates.

Description

technical field [0001] The invention relates to a spinning forming equipment for internally reinforced and externally thinned cylindrical parts, which is used for spinning and forming cylindrical workpieces to realize uniform forming of thin-walled shells, and belongs to the field of mechanical engineering. Background technique [0002] The current spinning forming technology includes ordinary spinning and powerful spinning technology, and regardless of the spinning forming method, it is generally necessary to manufacture a core mold. Process a core mold with the same diameter as required, and carry out profile thinning and forming. For the thinning treatment of cylindrical workpieces with extra-large diameters, it is very difficult to make extra-large mandrels at first. Even if it can be processed, its efficiency is particularly low, especially for the demand of those special industries. Spinning technology is costly and technically limited. In order to change the disadvan...
