Document Type and Number:
WIPO Patent Application WO/1989/000899
Kind Code:
A1
Abstract:
A method of making workpieces, for example springs with few leaves, consists in placing a heated workpiece (1) on a calibration die (2) and feeding it into a deformation zone to form an article of a desired profile, the deformation being effected starting from the middle area (3) of the workpiece simultaneously in the direction of its ends (4 and 5), both arms being formed by means of drawing or rolling. In a device for implementation of the method, the deformation unit is provided with a calibre (6) of a constant size, both arms of the workpiece being formed simultaneously during their passage through the latter, or the deformation unit comprises two carriages provided with idle rollers and moving in opposite directions.
