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： This invention concerns an active reconfigurable stretch forming tool, and in another aspect the invention is a method of stretch forming. The tool comprises an array of extensible shape forming elements which are driven in extension to produce the same force per unit area across a workpiece during shape forming. An array of limit switches are located in front of the array of shape forming elements, such that each shape forming element is driven in extension towards a respective limit switch during shape forming. In use, each limit switch is activated by the workpiece as it is shaped and each switch, upon activation, prevents further extension of the respective driven element. The tool and method are useful in the forming of three dimensional shapes in solid sheet metal or mesh, to produce panels for reflector antennas.

摘要： A stretch-forming press (10) for stamping continuously fed sheet metal (32) includes a ram (14), a base member (44), and a feed mechanism (20) configured to advance a strip of sheet metal through the stretch-forming press. A forming station (58) has a die (59) configured to form a desired pattern in the strip of sheet metal. A leveling station (86) has a pair of opposed jaws (88, 90) slidably received in corresponding recesses (92, 102) of the stretch-forming press, with the jaws oriented at an angle with respect to a direction of travel for the strip of sheet metal as it passes through the leveling station (86).

摘要： A cut-to-length steel coil processing line has an un-coiling reel, a temper mill, a stretcher leveler, a shearer, and a stacking apparatus arranged to sequentially process a continuous length of sheet metal. The line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the temper mill to the stacking apparatus without processing through the stretcher leveler when a determined thickness of the continuous length of sheet metal is at or below a selected measurement criteria. In the alternative, the line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the stretcher leveler to the stacking apparatus without processing through the temper mill when the determined thickness of the continuous length of sheet metal is greater than the selected measurement criteria. A method to be carried out on such a cut-to-length steel coil processing line is also disclosed.
