Claims

[Scope of utility model registration request]

Cooling water holes for inflow and outflow are provided on the roll shaft fixed to the yoke, and the roll body is connected to the roll shaft via two bearings arranged at both ends of the roll body in the direction of the rotation axis. The roll main body is rotatably supported, and an annular cooling water reservoir hole is formed inside the pressure surface of the roll main body by keeping the opening on the pressure surface side of the roll main body watertight and closing it with a lid body. A cooling water hole is provided in a water-tight manner between the outer peripheral surface of the roll shaft and the inner peripheral surface of the roll body between the bearings, and cooling water holes for inflow are provided in the roll shaft and the roll body, respectively. and the outflow cooling water holes are communicated with each other through the communication portion, and
1. A cooling device for a squeeze head roll in a pipe-making machine, characterized in that each cooling water hole for inflow and outflow provided in the roll body is communicated with the cooling water reservoir hole.
