The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
Consult Fig. 2,4, the utility model is applicable to that the forcing press 1 that a preferred embodiment of the double-toggle formula linkage of forcing press is suitable for comprises a support 11, and a slide block 12 and a driver element 13 of being arranged at this support 11, wherein, this driver element 13 comprises an alternating current motor 131, flywheel 132, belt that connects this alternating current motor 131 and this flywheel 132 133, a power transmission shaft 134 that is connected with this flywheel 132, and one is fixed in a bent axle 21 of this double-toggle formula linkage and the reduction gearing 135 that meshes with this power transmission shaft 134.
Consult Fig. 3~5, this double-toggle formula linkage comprises two gear units 2, described gear unit 2 along continuous straight runs are connected in this slide block 12 in regular turn, and respectively comprise the bent axle 21 of a driver element 13 that is operatively connected to this forcing press 1, toggle 22, crank that connects this bent axle 21 and this toggle 22 23, a guide pillar 24 that is connected this toggle 22 and this slide block 12, and synchromesh gear 25 affixed with this bent axle 21, wherein, described bent axle 21 distance to each other is less than described toggle 22 distance to each other.This toggle 22 has a top link 221 and a following swing arm 222, this top link 221 has a stiff end 223 that is rotationally connected with this support 11, and a link 224 that is rotationally connected with an end of this time swing arm 222, this time swing arm 222 has a drive end 225 that is rotationally connected with this guide pillar 24.This crank 23 has a pivot end 231.Described synchromesh gear 25 is to be meshing with each other and one of them synchromesh gear 25 is driven by this driver element 13.
