摘要:
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 with the following steps: a reference die and at least one reference punch are made, the reference die is attached to the die plate, by an optical measuring device usefully arranged on a base plate and/or die plate, the position of the upper edge of the reference die is measured and the position value stored, the reference die is removed, the adaptor plate with the reference punch previously attached therein, is moved 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, the sum of the reference die measurement and the reference punch measurement is obtained as the distance of the adaptor plate from the die plate and stored.
摘要:
Press for producing pressed parts from powdered material with a die which may be clamped to a die table arranged in a press frame, in which a mould cavity is configured with a recess, and at least one upper and lower punch which cooperate with the mould cavity, the mould cavity being defined by at least one slider, transverse press punch or a movable part of the die, which may be displaced transversely to the vertical axis of the upper and lower punch (main pressing axis), and adjusting drives for the upper and lower punch and the slider and/or the displaceable die part attached in the press frame, characterised in that a sensor measures actual conditions of the adjusting drive for the slider, transverse press punch or the displaceable die part, the actual conditions being compared in a control device with a desired value and the control device actuating the adjusting drive for a slider, the transverse press punch or the displaceable die part via the energy supply to the adjusting drive according to the difference between the actual and desired condition.
