Abstract: A full-electric servo vertical three-counter driving power spinning device includes a rack, and the rack includes a baseplate. A workpiece active rotating mechanism and an inner roller feeding mechanism are provided on the baseplate, an outer roller feeding mechanism is provided on the rack; the outer roller feeding mechanism is provided with an outer roller active rotating mechanism; the outer roller active rotating mechanism includes an outer roller active rotating motor and an outer roller, and the inner roller feeding mechanism includes an inner roller. A stress state of a cylinder material by adopting a combined method of an active rotation of a roller and an active rotation of a workpiece turntable is significantly different from that by a passive spinning of a counter-roller, thus improving a thinning rate of a wall thickness of a cylindrical member and a hardening properties of materials.

Abstract: An inner roller feeding device for a baseplate of a counter-roller driving power spinning equipment includes an inner roller column, an inner roller top plate, an inner roller upper plate, an inner roller lower plate, a cam, a cam mounting cylinder, inner rollers, inner roller shafts, a feed screw, a servo motor and a baseplate. According to the inner roller feeding device, a brake motor serves as a power source, the inner roller is driven by the cam through a worm gear drive to feed along a radial direction of a workpiece, such that an inner roller mechanism is small in size, large in adjustment range and high in positioning precision.
