Abstract: A forming assembly includes, a rocker having an operating surface defining a cavity, the operating surface including a first cavity surface and a second cavity surface, a saddle defining a space in which the rocker rotates, and a pad extending into the cavity and defining (i) an abutment surface which faces toward the saddle and defines a first plane, and (ii) a workpiece contact surface which faces away from the saddle and defines a second plane, wherein relative movement between the saddle and the pad when the first cavity surface is positioned in contact with the abutment surface causes rotation of the rocker within the space, wherein rotation of the rocker within the space causes the second cavity surface to advance toward the workpiece contact surface, and wherein the first plane intersects the second plane so as to define an angle ?.

Abstract: A composite anti-friction bearing structure comprising a bearing substrate and an anti-friction layer. The bearing structure can be in the form of bushings, wear plates, wear rings, etc. The anti-friction layer includes particles of an alloy which combines lubricity of molybdenum with the wear resistance and corrosion resistance of elements such as cobalt and nickel. The invention is particularly related to anti-friction bushings for use in die sets, presses and other heavy duty machinery.

Abstract: An extended length rotary bending and forming device and method for manufacture thereof, the combination of materials and process steps used in the manufacture resulting in the production of the desired durable long length heavy duty rotary bender.

Abstract: The invention relates to a press driven work tool module comprising a power unit and a work unit. Each unit comprises a fluid filled cylinder, a piston for reciprocation therein, and a piston rod. Hydraulic fluid within the power stroke displacement space of the power cylinder is in communication with hydraulic fluid in the work displacement space of the work cylinder, and hydraulic fluid within the return displacement space of the power cylinder is in communication with hydraulic fluid within the return stroke displacement space of the work cylinder. The power cylinder is provided with a moving top plate connected to the power piston rod and a spring arrangement for urging the top plate and power piston rod to the return position, such that a drive force acting on the power piston rod moves the power piston and work piston to the power and work ends of the respective cylinders against the spring bias.
