摘要： Provided is a method for producing a fuel cell separator, capable of easily roughening the surface of a sheet-like metal substrate to become a fuel cell separator and thus reducing the contact resistance of the resulting fuel cell separator. Specifically, the method is a method for producing a fuel cell separator from a sheet-like metal substrate, including pulling the metal substrate at least in one direction to plastically deform the metal substrate, thereby increasing the arithmetic average roughness Ra of the surface of the metal substrate after being pulled compared to that before being pulled.

摘要： A method and apparatus are disclosed which are suitable for use in the manufacture of two-piece metal containers. In particular, a way of making cups from metal sheet is disclosed using a combination of stretching and drawing operations.

摘要： A drawing support for a metal sheet drawing machine. In one implementation the drawing support is constructed of a plurality of plates positioned in series one after the other and coupled together so that at least a portion of the plurality of plates are compressed one against the other. In one implementation each of the plurality of plates has a window through which metal sheet to be drawn may pass, and a holder for holding the metal sheet when it is drawn.

摘要： A stretch-forming machine of the type wherein a pair of opposed curving jaws grips opposing ends of a metal sheet to be stretch-formed in a curved configuration. Each of the jaws are formed of an array of adjacent grippers movable relative to each other by respective hydraulic cylinders to define a part of the curve of the jaw. The improvement to the stretch-forming machine which is the subject of this application comprises a closed-loop servo-control means for moving each one of the grippers into a predetermined position relative to each other. Each of the servo-control means comprises a hydraulic cylinder position controller carried by the hydraulic cylinder of the one gripper for controlling hydraulic fluid flow to the hydraulic cylinder responsive to stored data representing the desired predetermined position of one of the grippers. A motor is provided for actuating the position controller in response to the data received by the position controller to move the hydraulic cylinder. Hydraulic cylinder position feedback means is positioned on the hydraulic cylinder for sensing the position of the hydraulic cylinder and communicating a signal representing the position of the hydraulic cylinder to the position controller.

摘要： A method for stretch shaping an elongated metallic extrusion is disclosed comprising the steps of applying axial tension to an elongated metallic extrusion in an amount sufficient to equal or exceed the yield strength of the extrusion. An external shaping die is applied against a perimetric portion of the outside surface of the extrusion. The die has working faces conforming substantially to a finished cross-sectional shape for the extrusion. While maintaining such tension the die is advanced along a length of the extrusion. An apparatus for stretch shaping an elongated metallic extrusion is also disclosed.

摘要： A sheet (4) to be stretched is gripped in gripping heads (1, 2) interconnected by pressure members 3, the gripping heads being moved apart by hydraulic cylinder units. Owing to the different lengths of sheet to be stretched, one of the gripping heads--the counter gripping head (2)--is movable and may be locked to the pressure members (3) in different positions. In order to facilitate better adjustment between the pressure members and the gripping head (2) opposite sides of the pressure members (3) are provided with teeth (12, 13) removably engageable by toothed locking members (14, 15). Engagement is carried out by hydraulic cylinders operating axially-displaceable wedges (16, 17) connected to the locking members (14, 15).
