Method and measuring system for obtaining a reference for a powder press

Method for determining a reference for a powder press, which comprises a die plate for attaching a die and an upper adaptor plate which may be actuated by a drive which is hydraulic, mechanical, electric or the like for attaching an upper punch, a lower adaptor plate which may be actuated by a hydraulic drive for attaching a lower punch or the die plate and at least one distance measuring system for the upper and lower punch and/or the die plate comprising the following steps:

• providing a reference die and at least one reference punch with known reference punch measurements,
• attaching the reference die to the die plate,
• measuring the position of the upper edge of the reference die by an optical measuring device usefully arranged on a base plate and/or die plate,
• storing the position value,
• removing the reference die,
• moving the adaptor plate with the reference punch previously attached therein in the direction of the die until the lower edge of the reference punch has reached the stored position of the upper edge of the reference die,
• determining the sum of the reference die measurement and the known references punch measurement as the distance of the adaptor plate from the die plate,
• storing the sum, and
• removing the reference punch, so that both the reference die and reference punch are removed prior to application of normal tools for pressing purposes.
