    PATENTANSPRÜCHE :    
1. Verfahren zur Eignungsprüfung eines zur spanlosen Verformung, insbesondere zum Tiefziehen bestimmten Materials, dadurch gekennzeichnet, dass auf den Prüfling (14) ein mit einer ebenen Bezugsdruckfläche (11) versehener Prüfkörper (10) aufgesetzt, dieser mit steigender Last belastet und die Eindringtiefe in das Oberflächenprofil in Abhängigkeit von der Belastung gemessen wird.

 or (plain and roller bearings). In this case, the measurement of the penetration path is sufficient only under compressive forces.



    PATENT CLAIMS:
1. A method for the suitability test of a material intended for non-cutting deformation, in particular for deep drawing, characterized in that a test body (10) provided with a flat reference pressure surface (11) is placed on the test piece (14), this is loaded with increasing load and the penetration depth in the surface profile is measured as a function of the load.

Claims (1)

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass nach Herstellung des der Drucklast entsprechenden statischen Gleichgewichts und Messung des entsprechenden Eindringweges auf den Materialprüfling eine ansteigende, das Verschieben des Prüflings zwischen den Druckstempeln (10, 12) einleitende, senkrecht zum Druck stehende Kraft (H) ausgeübt und der weitere Eindringweg der in Wechselwirkung stehenden Oberflächen sowie auch die zur Einleitung der Verschiebung erforderliche Kraft gemessen wird. 2. The method according to claim 1, characterized in that after establishing the static equilibrium corresponding to the pressure load and measuring the corresponding penetration path on the material test specimen, an increasing displacement of the test specimen between the pressure rams (10, 12) introducing force perpendicular to the pressure ( H) and the further penetration path of the interacting surfaces as well as the force required to initiate the displacement are measured. 3. Vorrichtung zur Ausführung des Verfahrens nach Anspruch l, gekennzeichnet durch einen beweglichen, mit einstellbarem Druck belastbaren Druckstempel (10) mit einer ebenen Druckfläche (11) und einem feststehenden Auflagestempel (12) mit ebener Druckfläche (13) von gleicher Grösse wie die Druckfläche des Druckstempels, und eine Messeinrichtung (18-23) zur Messung der gegenseitigen Verschiebung beider Stempel bei zwischengelegtem Prüfling unter Belastung. 3. Apparatus for carrying out the method according to claim l, characterized by a movable, with adjustable pressure resilient pressure stamp (10) with a flat pressure surface (11) and a fixed support stamp (12) with a flat pressure surface (13) of the same size as the pressure surface of the pressure stamp, and a measuring device (18-23) for measuring the mutual displacement of the two stamps with the test object placed between them under load. 4. Vorrichtung nachAnspruch3, gekennzeichnet durch eineamPrüflingmittelseinesSpann- backens (27) angreifende, senkrecht zum Druck wirkende, mit ansteigenden Zugkräften, zweckmässig über eine Zugfeder (26) arbeitende Zugvorrichtung und eine Einrichtung (25,28) zum Messen der die Einleitung der Verschiebung des Prüflings bewirkenden Kraft. EMI5.1 (11 bzw. 13) in bezug auf Material und Bearbeitung der Oberfläche dem zur spanlosen Verformung dienenden Werkzeug entsprechen. 4. Device according to Claim 3, characterized by a pulling device (25, 28) for measuring the initiation of the displacement of the test specimen, acting perpendicularly to the pressure, acting perpendicular to the pressure, with increasing tensile forces, suitably via a tension spring (26) causing force.
