JPS5596214A SHEARING MACHINE 失效
公开(公告)号：JPS5596214A
公开(公告)日：1980-07-22
申请号：JP30579

发明人： KIKUCHI YUUJI , OOTAKE YUKIO
IPC分类号： B23D15/04
摘要： PURPOSE:To decrease the moving distance of a shearing machine remarkably, and to miniaturize the size, by a mechanism wherein blance members, such as a balance cylinder, a spring, etc. are mounted so as to function between the center of revolution and an an axial core of a rotary support portion, in order to balance weight of each rotary member. CONSTITUTION:Balance cylinders 15, 19 are installed which are used for balancing weight of connecting rods 2 and an upper tool rest 5, a working end of the cylinder 15 is connected to a stay 16, and a shaft support 18 of a crank-shaft 1 is pushed up by means of a functioning end of the cylinder 19. The weight of the connecting rods 2 and the upper tool rest 5 balance by push-up of the stay 16. Weight applied to bearings of housings 3 from the crank-shaft 1, the connecting rods 2, the upper tool rest 5, etc. balances by push-up of the shaft support 18.
