  • Tool-clamping device and method of setting up a pipe cutoff machine
    Patent number: 4082020
    Abstract: A tool-clamping device especially for a pipe cutoff machine, and a method of setting up a pipe cutoff machine. The clamping device includes a base and an overlying cap between which the tool is clamped. Spring means within the base and cap urge the cap to a tool-releasing position. Hydraulic means within the base pull the cap to a tool-clamping position against the action of the spring means. In setting up the machine, a tool is lightly clamped in the device, moved into contact with a pipe chucked in the machine to adjust the overhang, and firmly clamped for cutting.
