Claims

[Scope of utility model registration request]

A roll shaft having a tapered surface on the outer periphery and an elongated hole formed in the shaft center from the end, a roll sleeve having a tapered surface matching the tapered surface and fitting onto the roll shaft, and this roll sleeve. a straightening roll that is fitted onto the outside and fixed via a spacer; a pull rod that is disposed within the elongated hole of the roll shaft and has one end locked to the roll shaft and the other end protruding from the end of the roll shaft;
a ring-shaped cylinder member having a cylinder portion at a position facing the outer periphery of the elongated hole of the roll shaft and fixed to a portion protruding from the elongated hole of the pull rod; and a ring-shaped cylinder member fitted into the cylinder portion of the cylinder member. a piston that urges the cylinder member away from the roll axis to generate a tensile force on the pull rod, and a piston that engages with the roll sleeve and is fixed to the cylinder member to generate a tensile force on the pull rod. A clamping device for a straightening roll in a roll straightener, comprising a tightening member that transmits a signal to the roll sleeve through the cylinder member and presses the roll sleeve to the roll shaft via a tapered surface.
