Abstract: A method is disclosed for forming a curved portion with a small curvature radius in an original tube while suppressing wrinkles and buckling. The method includes placing the original tube between a first die and a second die, and pressing one or more times on the original tube by bringing the first die and the second die closer together and pressing the first die and second die against the original tube, wherein the original tube has a circular cross-sectional shape in at least a portion thereof, the first die has a first curved surface, the second die has a second curved surface, in one of the pressing, cross-sectioning and bending are simultaneously performed on at least the portion of the original tube by pressing the first die and second die against at least the portion of the original tube; in the cross-sectioning, the circular cross-sectional shape of the original tube is reduced in diameter, and a diameter reduction rate in one time of the pressing is more than 0% and less than 10%.

Abstract: A cutoff apparatus is adapted to be positioned adjacent a roll-forming machine, and is particularly adapted for adjustably receiving and cutting bumper-length segments from a swept elongated shape made of high strength steel being extended from the roll-forming machine. The cutoff apparatus includes a carriage with rollers for rollingly engaging the elongated shape to align the carriage with the elongated shape, the carriage being adapted to periodically move with the roll-formed shape for a short distance as the roll-formed shape is being formed. The cutoff apparatus further includes a blade operably mounted to the carriage for cutting segments from the roll-formed shape on the fly. An overhead supporting device supports the carriage in a counterbalanced condition so that the carriage can pivot and/or translate as necessary to minimize undesirable stress on the roll-formed shape as the roll-formed shape extends through the carriage, thus providing a reduced need to critically align and maintain the alignment of the cutoff apparatus with the roll-formed shape.

Abstract: Method for forming a tubular metal member of a shape and length having an opened end and a closed end into an element which is formed of a different shape and length by forcing and thereby flowing the metal of the tubular member from one mold cavity to another. The method utilizes a form mold having an entrance cavity of a shape and length generally corresponding to the tubular member and in which the entire tubular member is initially located and an exit cavity of a different shape and length in which the flowing metal of the tubular metal member is forced to form the element having the shape and length of the exit cavity. The form mold has an entrance opening in a side wall thereof which is connected to the entrance cavity. The tubular metal is initially located entirely within the entrance cavity of the form mold, with the closed end thereof located adjacent the exit cavity and the opened end of the tubular metal member being located at the entrance opening to the entrance cavity. Means are provided for simultaneously applying a mechanical force and a hydraulic force in a first direction to the tubular metal member to thereby flow the metal of the tubular member from the entrance cavity into the exit cavity to form the formed element. The form mold has a passage leading from the exit cavity to a source of hydraulic fluid which reacts against the closed end of the tubular metal member in a second direction in opposition to the hydraulic and mechanical forces applied in the first direction to the tubular metal member in order to control the speed of the formation of the formed element. Further, a method is disclosed for initially setting up the mold to ensure that the tube will be formed as quickly as possible and yet will have no bends.

Abstract: A spin flanging machine for flanging the open end of container bodies, such as metal cans. The machine includes a drive shaft mounted for rotation on a supporting structure and a rotary turret is secured to the shaft and carries a series of flanging heads. Each head is provided with a plurality of flanging rollers which are adapted to engage the open end of the can. As the turret rotates, each head is rotated about its axis by the driving engagement of a pinion connected to the head shaft with a large fixed gear mounted on the supporting structure. The flanging heads are moved in a reciprocating manner towards and away from the can by a cam mechanism including a cam follower that is secured to the end of each head and engages a cam groove on the fixed supporting structure.
