Title:
MANUFACTURE OF CAMSHAFT
Document Type and Number:
Japanese Patent JPH01148434
Kind Code:
A
Abstract:
PURPOSE: To form a cam shaft having large strength and moreover a high precise shape by shaping a semiprocessed goods by hammering and kneading by tool segments which enclose it at least partially and exert a pressing force in the radial direction on it. CONSTITUTION: When a hammer shaft 1 is rotated, a hammering tool 2 is moved outward by a centrifugal force via a hammer rod 4. Also, when the hammer shaft 1 is stopped or rotated at a low speed, outward movement is executed by a spring force. When the shaft 1 is rotated, relative movement, which is the same direction as that of the shaft 1 but far lower speedy than that of the shaft 1, is induced in a roller gage 6 via a pressing roller 7 on a rolling track 5 by the hammer rod 4. And whenever the rod 4 passes beneath the roller 7, a pressing shock which is oriented in the radial direction being the working power of the hammering tool 2 is generated and transmitted to a work 9.
