  • Patent number: 9555458
    Abstract: An ironing ring for use in a press for ironing pressing or drawing of a workpiece. The ironing ring has a work surface which, upon deforming the workpiece, contacts the workpiece, and causes flowing of the workpiece material. In order to prevent friction deposits in the region of the work surface of the ironing ring, a microstructure, differing from the roughness of the work surface, is introduced into the work surface, which forms elevations and/or recesses in the work surface. Material particles remaining on the work surface after the deforming of a workpiece thus adhere less strongly to the work surface and can be stripped off during the next deforming process.

  • Publication number: 20110174045
    Abstract: For the manufacture of can bodies as they are needed for the manufacture of aerosol cans or beverage cans, a special tool 2 is provided which combines the manufacture of the cup as well as the transformation of the cup into a can body into a single tool 3. The process is based on preferably round metal sheets which are first drawn in a first draw-stretching step of the tool 2 into cups and then are draw-stretched in a second draw-stretch process, the further draw- and slide-down-stretch to form can bodies. The drawing arrangements are the same in both operating steps. The tools required therefore are simple sturdy tools providing for a simple sturdy manufacturing process.

  • Publication number: 20100192659
    Abstract: An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece.
