Abstract
PURPOSE: To provide an expanding-contracting apparatus by which the diameter of a mandrel can be arbitrarily selected and the mandrel can be expanded or contracted to a predetermined diameter when there is trouble in the piston rod position controller for an oil-hydraulic cylinder for driving.
CONSTITUTION: The strip winding mandrel consists of a shaft (a), a mandrel expanding-contracting cylinder (b), a piston (c) secured to one end of the shaft (a), a segment (d) secured to the other end of the shaft (a) and a wedge (e) which expands or contracts said segment (d). In this case, the expanding-contracting cylinder (b) is provided with the first and second pistons 4 and 5 and a cylinder 3 having a stopper 3a on the central inner surface. When a piston rod 2 is in the neutral state by applying the same pressures to the back sides of the first and second pistons 4 and 5 from the second and third ports 8 and 9, the mandrel is in the expanded state, and when either one of the ports 8 and 9 is opened to the atmosphere, the mandrel is in the over-expanded or contracted state.
