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. The resulting cups have the advantage of having a base thickness that is thinner relative to the ingoing gauge of the metal sheet.

摘要： The invention relates to a method for controlling the flow of material when deep-drawing a workpiece. The aim of the invention is to devise a method which better utilizes the drawing capacity of a workpiece and produces a more accurate shape, particularly at the bottom of the drawn part. Said aim is achieved by a method in which the deep-drawing process is performed incrementally and in which at least one bead is incorporated into the flange zone of the workpiece prior to each increment of the deep-drawing process, thus allowing the bottom to be more accurately shaped while preventing material from accumulating in the flange zone. The invention further relates to a deep-drawing device (2).

摘要： A stretch-forming machine of the type wherein a pair of opposed curving jaws grips (24,25) opposing ends of a metal sheet to be stretch-formed in a curved configuration. Each of the jaws (24,25) 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： Il comprend au moins deux ensembles (6) comprenant chacun des moyens (18) de traction sur une extrémité (8) de la plaque (5) et des moyens (19) de rotation de l'extrémité autour d'un axe (A) perpendiculaire au plan de la plaque. Lorsque cet axe ne passe pas par le milieu de l'extrémité, on ajoute avantageusement à l'ensemble des moyens de translation transverse de l'extrémité. Les ensembles sont disposés de façon que la plaque soit en équilibre sous l'effet des tractions.

摘要： The invention relates to a method of manufacturing a heat and humidity exchange plate of an air-to-air counterflow enthalpy heat exchanger, which comprises a supporting member (101) and at least one polymeric vapour-permeable membrane (102), characterized in that it comprises the following successive steps:
a - continuous formation of a semi-finished product for the supporting member (101) in the form of an expanded metal structure (1010) from a strip of thin metal foil (1011), whereby the operations of slitting in the transverse direction, stretching in the longitudinal direction and rolling over the entire width of the strip are successively performed;
b - providing the expanded metal structure (1010) according to the preceding step with a thin vapour-permeable polymeric membrane (102);
c - on the expanded metal structure (1010) provided with the vapour-permeable polymeric membrane (102), formation of corrugated and embossed shape elements of the future heat and humidity exchange plate (10) of the counterflow enthalpy heat exchanger (1) by means of omnidirectional deformation;
d - creating a circumferential shape of the heat and humidity exchange plate of the counterflow enthalpy heat exchanger (1) by removing excess edges.
In addition, the invention relates to a heat and humidity exchange plate (10) of an air-to-air counterflow enthalpy heat exchanger and to an air-to-air counterflow enthalpy heat exchanger with this plate (10).

摘要： To suppress occurrence of stress corrosion cracking in a weld due to tensile residual stress generated in a web or a middle rib in case of bend forming of an aluminum alloy extrusion having the weld on the web or/and the middle rib. In bend forming of the aluminum alloy extrusion, a peak position of tensile residual stress generated in the middle rib exists in a region other than the vicinity of the weld. Since the peak position is away from the weld by a distance, tensile residual stress in the weld is reduced, making it possible to suppress occurrence of stress corrosion cracking.

摘要： On décrit un procédé de moulage par étirage d'une extrusion métallique allongée (10), lequel procédé consiste à appliquer une tension axiale à une extrusion métallique allongée (10) en quantité suffisante pour égaler ou dépasser la résistance à la déformation de l'extrusion. Une filière (60) externe est mise en contact avec une portion du périmètre de la surface externe de l'extrusion (10). La filière possède des surfaces de travail qui se conforment sensiblement à une forme en coupe transversale de l'extrusion (10) achevée. Tout en gardant une telle tension, la filière (60) avance sur une longueur de l'extrusion (10). On décrit également un appareil destiné à mouler par étirage une extrusion (10) métallique allongée.
