  • Patent number: 7325437
    Abstract: The present invention is a long reach press comprising a low force actuator for operably urging first tooling into a working position. It further includes an opposed high force actuator for operably urging second tooling into engagement with the first tooling. The low force actuator includes a positive stop actuator including a slide block stop for operatively supporting and restraining movement of the first tooling when engaged with the second tooling. The slide block is moveable between a stop extended position and a stop retracted position.

  • Patent number: 6530313
    Abstract: A threaded member projecting from a press slide includes a projection on its upper end. A motor raises and lowers the threaded member in tandem with a slide adjustment mechanism. A plate disposed on a lower surface of a press crown is moved to slidably enclose the projection. The press slide is locked when the lower surface of the projection and the upper surface of the plate abut each other.

  • Patent number: 6089148
    Abstract: A fixed stroke power press safety stop block, manufactured of a light weight metal or plastic sufficient to withstand the dead weight of a ram and an attached upper die shoe preventing inadvertent downward movement of said ram. The stop block manufactured to be disposed on top of an existing die stop of a lower die shoe of said press and extending upwardly beneath the upper die shoe in the relative space between said die stop and said upper die platen when ram is in a upper most open position. Said block having a height equivalent to the fixed stroke of said ram less no greater than 0.250 of an inch permitting use of stop block in all die sets used relative to said press notwithstanding variances in shut heights. It is understood said shut height is determined by adjustment of ram crankshaft configuration causing contact by said upper die shoe with lower die stop at the lower most position of said ram.
