Patent number: 6523445Abstract: In a method and apparatus for rotating loose laminations in a loose lamination die, a strip is fed through the die to a rotatable blanking chamber of a blanking station. There, a punch engages with a die ring to punch a lamination free from the strip. The rotatable blanking chamber is biased in an upwardly direction. When the punch is not engaging with the die ring, the rotatable chamber is in an upward position wherein a gap develops between laminations retained at a bottom of the rotatable chamber, and those laminations lying directly below the rotatable chamber. The rotatable chamber can then be rotated without damage to the laminations at the gap because of the presence of the gap. A finger joint having an upper and lower portion is provided below the rotatable chamber which permits the gap to develop when the rotatable chamber is biased in the upward direction.Type: GrantFiled: May 1, 2002Date of Patent: February 25, 2003Assignee: Tempel Steel Company, Inc.Inventor: Mark Bender

Patent number: 4934230Abstract: A die stamping system includes opposed die members which clamp a metal workpiece to be shaped, cut or pierced after which the die members are moved away from one another and a part is subsequently ejected wherein the ejector is controlled for a selected delay time by a plurality of cylinder assemblies mounted in a manifold so that they are connected to a source of inert gas such as nitrogen under high pressure and to a source of hydraulic pressure. Each cylinder assembly includes a piston associated with and exposed to the nitrogen in the manifold. The cylinder assemblies are connected to a single hydraulic valve which has associated therewith an accumulator and which is operated simultaneously to actuate the cylinders. The hydraulic lines to the cylinders are provided in the manifold.Type: GrantFiled: August 24, 1988Date of Patent: June 19, 1990Inventor: Bernard J. Wallis

Patent number: 4892019Abstract: A cutter for punching a sheet of material having a fixed block disposed so as to face one side of the sheet, a moving blade disposed at the opposite side of the sheet relative to the fixed block, and a transporting roller disposed inside the moving blade. A punched-out portion is thereby transported along with a punched-remainder portion.Type: GrantFiled: August 14, 1987Date of Patent: January 9, 1990Assignee: Fuji Photo Film Co., Ltd.Inventors: Mikio Kogane, Mizuho Nishimura, Tsutomu Kimura

Patent number: 4862779Abstract: A cutter of the present invention comprises a punching member having a punching edge and a receiving member for receiving the punching force of the punching member, the receiving member having a sandwich structure comprising two plate materials and an elastic body held therebetween. Therefore, the receiving member is capable of elastically holding the punching edge during punching.Type: GrantFiled: May 18, 1988Date of Patent: September 5, 1989Assignee: Fuji Photo Film Co., Ltd.Inventors: Mizuho Nishimura, Nobuo Watase, Yasunobu Sakaguchi, Mikio Kogane

Patent number: 4846029Abstract: A heated aluminum log which is to be sheared is inserted through a stationary die and a movable die. A clamp of the stationary die is then moved towards an axis of that die to clamp the log against a diametrically opposite portion of the internal surface of the stationary die. Opposite members of the stationary die are then moved towards each other in a direction perpendicular to the direction of movement of the clamp, to limit expansion of the sheared log. The movable die is then moved to shear the log.Type: GrantFiled: February 19, 1988Date of Patent: July 11, 1989Assignee: Mechatherm Engineering LimitedInventor: John A. Gardner

Patent number: 4823660Abstract: A device and method for cutting labels from a strip of heat meltable material comprises a frame, a die plate mounted for resilient movement on the frame and a punch mounted for movement toward and away from the die plate. The punch carries a cutting edge which cooperates with a die surface of the die plate to cut a label. A reciprocating device includes a spring loaded plunger which moves the die plate with its cutting edge into contact with the die surface of the die plate. The die plate is spring mounted to the frame so that excess movement of the punch toward the die plate is absorbed by the springs of the die plate. Any additional excess movement is absorbed by the spring loaded plunger. The die plate may also be provided with a hole conforming substantially to the outer contour of the label. The edge follows the contour of the hole but it is dimensioned slightly larger than the hole so that a margin of die surface remains around the hole against which the cutting edge operates.Type: GrantFiled: February 20, 1986Date of Patent: April 25, 1989Inventor: Frederick Forthmann

Patent number: 4774865Abstract: A die stamping system for use in a fine blanking apparatus that includes opposed die members which clamp a metal workpiece to be cut and pierced after which the die members are moved away from one another and the slugs pierced from the blank and the cut blanks are subsequently ejected wherein the ejector is controlled for a selected delay time by a plurality of cylinder assemblies mounted in a manifold so that they are connected to a source of inert gas such as nitrogen under high pressure. Each cylinder assembly includes a first piston associated with and exposed to the nitrogen in the manifold and a second piston engaged by the first piston and urged outwardly into engagement with a punch base.Type: GrantFiled: September 22, 1987Date of Patent: October 4, 1988Inventor: Bernard J. Wallis

Patent number: 4750393Abstract: A method of punching cylindrical tubes with openings from the inside to the outside. In accordance with the method, the punching apparatus includes a mandrel that slidably supports the dies and a backup die that includes a slug ejecting punch which serves the dual function of ejecting the slugs from the backup die and also retracting the punches.Type: GrantFiled: June 15, 1987Date of Patent: June 14, 1988Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Hiroshi Yamagata

Patent number: 4730528Abstract: Button cover cutting press apparatus includes a frame and a cutter secured to a movable cutting head, and the cutter head and cutter are moved relative to the frame on a central guide rod by means of a lever. The guide rod also acts as an ejector to remove the material cut by the apparatus.Type: GrantFiled: July 25, 1986Date of Patent: March 15, 1988Inventor: Bradley T. Haskins

Patent number: 4728239Abstract: A cap lining machine constructed with a minimal number of mechanical parts includes a spring-biased shuttle feed for moving the caps into the punching and insert position. A cam pulls the shuttle back against the bias of the spring; so that upon release by the cam, the shuttle pushes the caps to the insert position. If a cap becomes jammed, the spring-biased shuttle simply is held back against the spring bias to prevent breaking of caps or parts of the machine. A tamper also is concentrically mounted within a hollow punch and is controlled by a rocker arm assembly to press punched inserts out of the lower end of the punch and seat them into the caps. The tamper may be cleaned by removing it completely from the top of the punch.Type: GrantFiled: October 17, 1986Date of Patent: March 1, 1988Assignee: Top Seal CorporationInventors: Thomas G. Kieran, Newton Rickenbach

Patent number: 4708042Abstract: With a punching machine with at least one punching carriage, which can be moved transverse to the advance direction of a material belt, with a piston cylinder unit arranged in the punching carriage, which effects the punching stroke of a tool stamp and, with an abutment for receiving a tool die-plate, it should be guaranteed that, a female die is always realized absolutely exactly below the punching material opposite the male die. This is achieved in that, the abutment is firmly arranged in a defined position to the piston cylinder unit in the punching carriage carrying the piston cylinder unit.Type: GrantFiled: April 28, 1986Date of Patent: November 24, 1987Assignee: Schon & Cei, GmbHInventor: Klaus Jung
