DEVICE FOR CONTINUOUS AND NON-CUTTING SEPARATION OF DISC OR BOLT FROM ROUND BAR

摘要

PROBLEM TO BE SOLVED: To provide a device for continuous and non-cutting separation of a disc or a bolt from a round bar. SOLUTION: This device for continuous and non-cutting separation of the disc or the bolt from the round bar comprises a separating and rolling device and also comprises an inlet channel having a forward feeding device for clamping and rotating a workpiece to move it forward in the axial direction placed before the separating and rolling device. The separating and rolling device has at least two cutting rolls placed around the workpiece to be processed. Height, 10 of a helical member 2 of at least one cutting roll 1 is equall to or longer than a radius r of the round bar 5 to be separated in a separating part section TA, and the helical member 2 of the other roll or each of other two rolls n working together with the cutting roll 1 is formed so as not to collide with the helical member 2 of the first cutting roll 1 in the separating part section TA.
