Abstract:
A pressing machine, particularly a fast operating pressing machine equipped with a pressing head forced into longitudinal jigging motion by an eccentric disk, having an eccentric shaft, through a crank arm, said pressing head (12) having a lower pressing block (13) removable from the work range above the bench (46) and an upper pressing block (14) arranged slideably in relation to the lower pressing block (13) and forced into jigging motion by the crank arm (9) and there is a connecting element (15) releasably connecting said lower pressing block (13) to the upper pressing block (14); said lower pressing block (13) having at least one of a suspension point (17) and a lifting point (23); a suspending element (18) is connected to said suspension point (17), suspending element (18) is cast through reels (19 and 20) and strained by a counterweight (21) and a stop (26) impacting onto the upper dead point position of the jigging motion of the upper pressing block (14); said lifting point (23) being elevated by a cylindrical spring (22) and a backstop (25) impacting onto the upper dead point position of the jigging motion of the upper pressing block (14), characterised by having an electromagnet (16) for operating said connecting element between a connecting position, wherein the lower pressing block (13) is fastened to the upper pressing block (14), and a released position, wherein said lower pressing block (13) can freely slide in relation to said upper pressing block (14).
