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.
