摘要： A fabrication method of a metal shell to be installed on a park plug is provided which is made up of a small-diameter portion, a large-diameter portion, and a wrapping portion. The wrapping portion is to be wrapped by staking about the spark plug to achieve installation of the metal shell on the spark plug. The method comprises pressing a workpiece with a punch to shape the wrapping portion of the metal shell in a first cold forging process and processing the workpiece to shape the small-diameter portion of the metal shell in a second cold forging process different from the first cold forging process. This produces the metal shell which is less susceptible to cracks when installed on the spark plug and has an increased service life.

摘要： Cathode cans for use in air depolarized cells, and cells made with such cans. The side wall is stronger than the bottom wall, and has a smoother outwardly-disposed surface than the respective bottom wall surface. Strength, and thus hardness, of the side wall relates to strength, and thus hardness, of the bottom wall, as hardness of 130-185 relates to hardness of 93-117, on the Vickers scale. Preferred hardness of the side wall is about 130 to 185; and of the bottom wall is about 93 to 117. The side wall is drawn, and an outwardly-disposed surface of the side wall is ironed. As ironed, the surface finish is related to surface finish of the bottom wall, at the same stage, as surface finish RA of less than 2, preferably about 0.5 to about 1.5, microinches, is related to surface finish RA of about 2 to about 5, preferably about 2.5 to about 4.5, microinches. Thickness of the side wall is generally up to about 85 percent as great as thickness of the bottom wall. In methods of forming cathode cans in a metal strip, a die has an initializing land, an inner side wall, a cavity inwardly of the inner side wall, and a lip between the initializing land and the inner side wall. Ratio of outer radius of the lip to inner radius of the lip is about 2/1 to about 8/1. Ratio of clearance between punch and die to thickness of the metal strip is about 0.5/1 to about 0.85/1, whereby moving the punch and metal strip into the cavity draws the metal, and irons the outer surface of the metal.

摘要： A process for the production of a can comprising a base and a tubular body from sheet metal which is coated on at least one side with a layer of plastic, in which process, firstly, a round disc is produced from the sheet metal, which disc is then deep-drawn into a cup which is coated at least on the outside with the layer of plastic, after which this cup is formed into a can by wall ironing, the wall ironing taking place in a single stroke by moving the cup successively through a plurality of wall-ironing rings, in which process an optionally metal-coated steel sheet is used as the sheet metal, and in which process the entry angle from each of the successive at lest three wall-ironing rings is smaller than that of the preceding ring.

摘要： A process for hydroforming sheet metal, in which a blank (1) is secured with the help of a blank holder (2′, 2″, 2′″) on a matrix (4′) provided with a cavity (3′) for stamping the blank (1) with the help of a die (5′, 5″, 5′″) entering the matrix, characterized in that during the stamping phase, the play between the die (5′, 5″, 5′″) and the blank holder (2′, 2″, 2′″) is confined within a range of values preventing, between the die and matrix, the formation of a fold, as a function of one and/or the other of the following parameters: pressure of fluid in the cavity (3′) of the matrix (4′), and position of the die (5′, 5″, 5′″) relative to the matrix.
