ABSTRACT:
An apparatus used for measuring a holding force expected to be applied to a pressure member of a press, before the lower and upper dies and the pressure member are installed on the press. The apparatus includes a measuring member to be placed on cushion pins of the press associated with a fluid-actuated cylinder via a cushion pad. A sensing element is disposed on the measuring member or a main slide carrying the upper die, such that the holding force produced by force applying means which includes the cylinder acts on the sensing element, when the measuring member is lowered with the sensing element by the main slide in its downward movement towards a bolster on which the lower due is fixed. A load detecting device is disposed on the sensing element for detecting the holding force acting on the latter. The apparatus also includes a device for recording the holding force as detected by the load detecting device.
