  • Patent number: 7112049
    Abstract: The invention is concerned with a compression molding device (1) with a tool (3) generating at least a part of the work-piece geometry. At least one pressure measuring means (5) and/or at least one pressure space (4) is located directly below the work-piece associated surface (3.3) of the tool (3). Besides this, the work piece (3) selectively exhibits at least one first part (3.1) which is a tool template generating the shape of the work piece and a second part (3.2) forming the base body, wherein a measuring strip (6) is provided between the tool template (3.1) and the base body (3.2). As an optional refinement, the measuring strip (6) is an elastic intermediate layer with a smaller modulus of elasticity than the base body (3.2).

  • Publication number: 20050279152
    Abstract: Deforming tool and process for manufacturing thereof in the deformation of work pieces the outer force acts on the deforming tool and/or the work piece, which causes a flow of the work piece material and its plastic deformation into a shape determined by the tool shape. Therein the tool is subjected to high friction wear forces. In the framework of the ever shorter production cycles it is also necessary that deforming tools must be produced ever more rapidly, wherein their friction wear resistance must be maintained to the greatest extent possible. The inventive deforming tool includes a lower and an upper tool, wherein lower and/or upper tool include a shape determining shell and a backfill for supporting thereof, wherein lower and/or upper tool are comprised at least in part of laminated material layers or powder particles joined to each other, wherein the deforming tool includes an elastic intermediate layer between lower and/or upper tool (backfill) and the shape determining shell.

  • Patent number: 6439764
    Abstract: The thermographic examination of functional surfaces of forming tools in the forming process is important for the selection of an optimal tool material or an optimal coating material for a particular forming process and for a particular workpiece composition, and also for the optimization of process parameters of the forming process. The task of the present invention is comprised therein, to develop a device and a process, which enables the rapid and simple thermographic examination of functional surfaces of forming tools during the forming process. This task is solved by a process and a device, in which the sought after temperature distribution of the functional surfaces during the forming process are conducted, from point of origin, through a channel, in the direction of a temperature measuring device, via thermal radiation or, in certain cases, thermal conductivity.
