Abstract

1338940 Press brakes; shearing F J DEJAGER 27 Oct 1971 [30 Get 1970] 49913/71 Headings B3E and B3W A press or guillotine comprises thrust means, e.g. hydraulic rams 12À1, 12À2, and at least one pair of toggle struts, the or each pair of struts having an anchor strut, e.g. 16À1, 18À1, and a working strut e.g. 16À2, 18À2 whose inner ends are pivotally connected together and whose outer ends are pivotally connected to an anchor part 30 and a working head 20À5 respectively, the working strut constituting the working arm of a second order lever, e.g. 16À6 18À6 to whose effort arm e.g. 16À4, 18À4 the thrust means are pivotally connected. At the end of a working stroke the included angle defined by the struts exceeds 150 degrees.
