Title:
MULTI-STAGE FORCE AMPLIFYING DEVICE FOR PUNCHING, DRAWING, AND EXTRUDING PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2019/100460
Kind Code:
A1
Abstract:
A multi-stage force amplifying device for punching, drawing, and extruding production, relating to the technical field of press machine operation. The device comprises a force assisting mechanism (1) and a force applying mechanism (2). The force assisting mechanism (1) comprises a push rod (17), a base (11), a platen (12), a push block (13), and linkage groups (14); an arc-surfaced profile member (13-1) and an arc-shaped slide groove (13-2) are formed on the push block (13); each linkage group (14) comprises an upper linkage (14-1), a lower linkage (14-2), a back pulling rod (14-3), and a pin shaft (14-4); and a slide block (15) is provided between the push block (13) and one end of the upper linkage (14-1). The force applying mechanism (2) comprises a left linkage (21), a right linkage (22), an ejecting block (23), and a connecting shaft (24); one end of the left linkage (21) and one end of the right linkage (22) are both hingedly connected to the same connecting shaft (24); and the other end of one of the left and right linkages (21, 22) is hingedly connected to a rack, and the other end of the other one of the left and right links (21, 22) is hingedly connected to a movable plate (25). The device has the advantages that the structure is simple, a novel transmission mode is achieved, the transmission capability is amplified by a plurality of times or more, the energy consumption is effectively reduced, the structure is compact, the volume is small, impact vibration is reduced, and the impact noise is lowered.
