摘要： A machine such as an injection moulding machine or a press for installing fasteners into workpieces has a ram (10) coupled to a hydraulic piston and cylinder (16) via a toggle linkage (22,24) which is movable by a pneumatically controlled piston and cylinder (14) between a folded condition and a substantially collinear condition. Such movement of the toggle (22,24) advances or retracts the ram (10) towards or away from an anvil (18). The toggle (22,24) can transmit force from the cylinder (16) to the ram (10) only when the toggle (22,24) is in the collinear condition and hence when the ram (10) is in close proximity or contact with the anvil (18). In this way, the operators hands are safeguarded without the need for the provision of a machine guard.
摘要翻译：一种诸如注射成型机或用于将紧固件安装到工件中的压力机的机器具有经由肘节联动器（22,24）联接到液压活塞和气缸（16）的压头（10），所述肘节连杆机构（22,24）可通过气动控制的活塞运动，气缸（14）处于折叠状态和基本共线状态之间。肘节（22,24）的这种移动朝向或远离砧座（18）前进或缩回。肘节（22,24）只有当肘节（22,24）处于共线状态时才能从气缸（16）向冲头（10）传递力，因此当冲头（10）接近或接触时与砧座（18）。以这种方式，操作者的手被保护，而不需要提供机器护罩。
