Abstract
The technical field of metal plastic forming processes and equipment, and provides a device and method for forming shaft part by two-roller flexible skew rolling. The device comprises two skew rollers, a guiding plate, two guiding cylinders and an axial pushing device; the skew rollers can do same-direction rotation motion, radial feeding motion and tilt angle adjustment motion; the guiding plate is arranged between the two skew rollers and is used for limiting the radial movement of a blank; the two guiding cylinders are arranged on the two sides of the two skew rollers to limit swing of the blank; and the axial pushing device is arranged at one end of the blank and is used for applying axial pushing force to the blank, and the blank is rolled into a shaft part in a space defined by the skew rollers and the guiding plate. The method of the invention includes a radial compression forming process, a roller tilting forming process, a skew rolling diameter reduction forming process and a roller leveling forming process. The device and method for forming shaft part by two-roller flexible skew rolling have the advantages that forming equipment is simple, the tonnage is small, flexible p…
