Abstract:
In a linear power module for actuating a tool ram of an industrial tool, said power module having a power ram arranged to undergo motion along a power axis,a power enhancing unit disposed between said power unit and said industrial tool comprising: (1) a frame; (2) an input member coupled to said power ram arranged to undergo movement in a first direction within said frame from a first position to a second position, wherein said power ram is operable to exert a primary force on said input member to effect said movement in said first direction; (3) an output member coupled to said tool ram; (4) a power enhancing mechanism coupled to both said input member and said output member, said power enhancing mechanism comprising a plurality of interleaved toggle links, wherein a first toggle link is coupled to the output member at a first pivot point, and a second toggle link is coupled to the output member at a second pivot point distinct from the first pivot point; and said power enhancing mechanism arranged so that upon said movement in said first direction of said input member said output member undergoes movement in said first direction and exerts a secondary force on said tool ram that is greater than said primary force for a portion of said movement of said output member, wherein said tool ram has a tool axis coaxial with said power axis.
