    Abstract: A method of manufacturing a diaphragm backing plate for use in a brake booster comprising the steps of moving a coil of metal having parallel first and second sides that define a first width to a first station. Applying a stamping force to remove a section from the coil of metal and create a first plate defined by equal and parallel sides that are connected to each other by an arcuate segments each having a radius that is approximately equal to one-half of the width of the coil plus a minimum width of a lip. Moving the plate to a second station and thereafter rolling a peripheral surface thereon to define a uniform diameter for the plate that is approximately equal to the first width of the roll less twice the minimum width for the lip.

  • Patent number: 7036348
    Abstract: A method and apparatus for forming a rolled reinforcing rib in an end shell of a container body in a single stroke and at a single station of a double action press prior to removal of the shell from the press. A blank disc is cut from sheet material by a punch core advanced by an outer ram. A chuckwall is then formed between a central panel and an outer flange. The central panel is clamped against a die core and a portion of the chuckwall is clamped against a die core ring. An unclamped portion of the chuckwall is located in a void formed between the punch core and die core ring and is rolled into the reinforcing rib upon continued advancement of inner and outer pressure sleeve while maintaining a tight clamping engagement of the central panel and outer flange of the blank disc. Simultaneous removal of the clamping force applied by the punch core and inner and outer pressure sleeves retain the rib in its rolled condition.

  • Patent number: 7007535
    Abstract: A method and apparatus for aligning opposed telescopically engageable cut ring and blank and draw die when mounted in a can body forming press to form non-round disc-shaped blanks which are subsequently formed into container bodies. A pair of opposed precision formed notches are formed in the peripheries of the spaced press components and a precision formed key is inserted into the notches. The key is then slidably removed from the notches. The notches are precisely located with respect to each other and to major and minor axes of the press components so that said major and minor axes align with each other when the key is seated in the notches.

  • Patent number: 6978532
    Abstract: A method of forming a durable mower bed blade is provided in which the grain of the metal is perpendicular to the longitudinal axis of the blade. The blade is formed in part by coining the blade on a hydraulic press which strengthens the cutting edge and other areas to prevent chipping and cracking. Additional steps in the process include shearing the blade to a proper width, heat treating and grinding the edge of the blade to sharpen it.

  • Patent number: 6658911
    Abstract: Method and apparatus for forming end shells for containers with a peripheral curl and an annular reinforcing rib in a single stroke cycle of a press which includes a punch core, a punch shell, and a pressure sleeve carried by an inner ram of the press. A cut edge is carried by an outer ram for forming a flat disc-shaped blank at a first level from a strip of sheet material. A die core is mounted on the base at a second level and is surrounded by concentric inner and outer die core rings. A cup-shaped blank is formed from the flat blank by movement of the punch core, pressure sleeve, and punch shell through a blank and draw die. The cup is clamped at the second level between the die core and punch core and formed into an end shell by movement of the punch core, pressure sleeve, and punch shell into clamping engagement with the die core, and inner and outer die core rings.

  • Patent number: 6539767
    Abstract: A method and apparatus for forming a container component has a fixed stock plate and cut edge mounted on a base at a first level for forming a disk-shaped blank from a strip of sheet material. A blank and draw die is mounted at a second level which forms the disk-shaped blank into a shallow cup upon advancement of a punch assembly through the die. A profile pad is mounted at a third level on the base and imparts a profile on the bottom wall of the shallow cup as the punch assembly continues a downward stroke. An air stream ejects the profiled container component from the press at the third level.

  • Patent number: 6408670
    Abstract: A carrierless progressive die system and method for improving part quality and reducing cost. A strip of sheet material advances between a plurality of die stations along a continuous planar surface of a die lifter and stripper pad combination formed or assembled as a single piece. The width of the sheet material is substantially the same as the width of a finished part and its outer edge portions are maintained structurally rigid during operations at the various die operations by providing centrally positioned lances between die stations and holes at the distal ends of the lances which prevent propagation of the lances during stretching and forming of the sheet material.

  • Patent number: 6389866
    Abstract: A mounting cup for an aerosol container having radially outward extending dimples on the body portion of the mounting cup and radially inward extending indents in the skirt portion of the mounting cup; both the dimples and the indents being aligned with the longitudinal axis of the mounting cup. In the preferred form of the mounting cup, three aligned dimples and indents are spaced equidistant about the circumference of the body portion and the skirt portion, respectively. Additionally, the method of this invention comprises forming a mounting cup having dimples and indents aligned with the longitudinal axis of the mounting cup, wherein the indents are formed in the last stage of a progressive die stamping operation through displacement of the metal of the mounting cup into a recess in the outer surface of the pilot tool during the formation of the skirt portion of the mounting cup.
