  • Device for feeding auxiliary tools into working zone of press
    Patent number: 4186588
    Abstract: The present invention relates to devices for feeding an auxiliary tool into the working zone of a press and can be used most efficiently in hydraulic free-forging presses. The device comprises a body in the form of a horizontally-movable platform located close to a supporting element and mounting a number of tool rods which are set with a provision for being moved relative to the platform by a discrete feed mechanism and for turning in a vertical plane around the supporting element. This layout of the device broadens considerably the technological capabilities of the press and reduces the manual labor and the time spent for feeding the tool.
