Abstract: A single action press for forming a shell used to make a can end includes a first tool and an opposed second tool. The first tool includes a die center insert that performs a forming operation on disc cut from a sheet of end material. The first tool is configured and arranged wherein force is supplied to the die center insert during the downstroke and force is removed from the die center insert at the bottom of the downstroke and at the start of the upstroke, to thereby enable the die center insert to disengage from the shell. One specific embodiment uses a die center piston and compressed air to apply force to the die center insert. Another embodiment uses a cam and cam follower arrangement to remove axial forces at the bottom of the downstroke and either springs or gas pressure to apply force to the die center insert during the downstroke.

Abstract: A monitoring and alarm system is disclosed for a rolling mill in which oil is pumped from a reservoir via feed piping and branch feed lines to oil film bearings and oil is returned from the bearings via branch drain lines and return piping to the reservoir. The system comprises sensors positioned in at least one of the branch feed lines, the branch return lines and the bearings. The sensors are operative to sense diverse parameters indicative of bearing operating conditions and to generate status signals representative thereof. A controller evaluates the status signals and triggers warning signals when the status signals indicate that the bearings are in danger of being damaged by continued operation. Alarms respond to the warning signals and alert mill operating personnel to such danger.

Abstract: A bottom tool/bending die for use in sheet metal forming. The bottom tool includes a pair of movable dies that provide substantially continuous support of a work piece as it is being deformed. Each die includes an upper surface configured to contact the work piece and having an inner and an outer edge. As the die moves in the tool, the inner edge of the upper surface is closer to a center of rotation of the die than the outer edge. In some embodiments, the upper surfaces of the dies are shaped so that a fixed separation is maintained between the inner edges of the dies as they rotate. In at least one embodiment, sector gears are used to control the motion of the dies.

Abstract: A spiral pipe machine includes a feeding assembly for continuously feeding a web of material, and a forming assembly for accepting the web. The forming assembly bends the web to form a first section of a spiral pipe having a first predetermined diameter. A controller is employed for selectively instructing the forming means to change its configuration so as to give a second section of the spiral pipe a second predetermined diameter. The controller is capable of controlling the forming station to transition from the first predetermined diameter to the second predetermined diameter during the continuous feeding of the web.
