DIMENSION DISPLAYING DEVICE FOR MOLDING OR SHEARING MACHINE OF METALLIC SHEET AND PRESS DEVICE USING SAID DEVICE

摘要

This dimension indicator for sheet-metal folding, bending or shearing machine tools comprises a measuring apparatus capable of displaying the distance from the adjustable stop member provided for positioning the workpiece to a reference plane. The device comprises structure for correcting the consequence of a displacement of the reference plane, in the form of a mechanical device coupled to the machine adjustment member and adapted to act directly or indirectly upon one of the component elements of a coupling or a data transmission disposed between the member controlling the stop member and the measuring apparatus, so as to actuate this apparatus.
