  • Patent number: 8959771
    Abstract: A method of manufacturing a shell from sheet metal for a room air conditioner/heat pump is shown. The sheet metal is stamped and formed to a U-shaped rectangular shell with open ends and a shell brace. Flanges on the outer edge of the U-shaped rectangular shell overlap at corners with (a) adjacent flanges or (b) the shell brace. Both the U-shaped rectangular shell and shell brace are inserted into an assembly machine where the corners are clinched and punched. The outermost flange at each corner is punched to a fixed diameter, but the innermost flange or the shell brace is only punched to a conical shape. Screws are inserted at each corner that pass through the fixed diameter to threadably engage only the conical shape of the innermost flange or shell brace.

  • Patent number: 8322177
    Abstract: The present invention relates to a method and tooling suitable for handling closure blanks (5) having an external radius (6) at their cut edge at production speeds of about (1200) closures per minute. The external radius (6) limits formation of “angel hair” (a common problem in metal closure production). However, reversing the external radius causes a problem, when producing metal closures having a conventional inward curl at their peripheral edge. Accordingly, the invention proposes a modified curling rail (40) having a first portion (41) to uncurl the external curl (6) on the closure blank (5) and a second portion (45) to urge the straightened side wall of the closure blank (5) towards an inward curl.

  • Patent number: 8312753
    Abstract: A method of forming a hollow curled portion on a hollow body, the curled portion being oriented from one end to the other end of the hollow body. The method includes a bending step of curving an end of the hollow body toward another end of the hollow body, thereby forming a curled portion, an ironing step of ironing the curled portion with a die, and a recurving step of stopping the die from ironing the curled portion and allowing the curled portion to recurve under its own resiliency in a direction opposite to the direction in which the end of the hollow body has been curved. The ironing step and the recurving step are repeated.

  • Patent number: 8286459
    Abstract: In a method for producing a two-piece can, a circular disk of a laminated steel sheet having a thermoplastic resin coating layer is subjected to multistage forming to produce a final formed body having a height h, a maximum radius r, and a minimum radius d (the case where r is equal to d is also included). Forming is performed so that the height h, maximum radius r, and minimum radius d of the final formed body satisfy the relationships 0.1?d/R?0.25 and 1.5?h/(R?r)?4 with respect to a radius R of a circular disk before forming whose weight is equal to that the final formed body. At an intermediate stage of forming, a formed body is subjected to heat treatment at a temperature of not less than a melting point of a thermoplastic resin but not more than a temperature 30° C. higher than the melting point.

  • Patent number: 8245556
    Abstract: A thin walled body is deformed in a process in which the body is gripped securely in a holding station and, while gripped in the holding station, tooling engages to deform the peripheral wall of the body at a predetermined wall zone. The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station.

    Abstract: The water heater (2) or steam generator comprises a chamber (4) in two sections (5, 6) formed in particular by stamping. Inside this chamber a heating element (8) is arranged, which has a spiral-shaped main section (10) and two end sections (11, 12) passing through two circular openings of the chamber. The two end sections are welded to the chamber by a laser beam such that the weld obtained is continuous and ensures a good mechanical fixture of the heating element and an adequate tightness for the water heater or steam generator. For this purpose, a flange (18) is arranged at the periphery of each opening. Moreover, the two sections of the chamber have a widened edge (28) to allow them to be welded effectively.

    Abstract: A tooling assembly for scoring a can end is provided. First and second opposing tool members cooperate to create a depression in the can end, and to form a scoreline within the depression. A conversion press for converting a can end shell into a can end, and a method for scoring a can end are also provided. The method includes engaging a first side of the can end with a score knife, supporting at least a portion of a second side of the can end with a score anvil, depressing the can end into a cavity of the score anvil to form the depression, and forming the scoreline within the depression. The depression and scoreline are formed substantially simultaneous within the same tool station of the conversion press. A sealant, which is applied to the scoreline, forms a pool within the depression, thereby completely covering the scoreline.
