Emergency candle for use between fixed support surface and weight part surface in stamping press to support upper tool of press, has detecting member cooperating with visualization unit to allow visualization of correct contact position

摘要

The candle (1) has an upper surface (1b) comprising a detecting member (6) i.e. ball, that detects a correct contact position between the upper surface and a surface (3a) of a weight part (3). The detecting member cooperates with a visualization unit to allow visualization of the correct contact position on the candle. The detecting member is movable between a position and another position in which the detecting member is retracted under effect of contact between the detecting member and the surface of the weight part.
