摘　　要：压力机在工作中因某些原因可能会出现过载现象。为防止过载现象出现,压力机一般都设有液压过载保护装置。在传统结构中,理论上可以控制过载,但在机加、装配以及压机工作中,传统结构存在诸多问题,所以需对液压过载装置进行结构优化。本文旨在对机械多点闭式压力机液压过载装置的机械结构进行改进设计,提出最为合理的设计结构,解决传统结构中的缺点,发挥优化结构的结构特点,节约成本。The press may be overloaded due to some reasons.In order to prevent the occurrence of overload,the press is generally equipped with a hydraulic overload protection device.In the traditional structure,the overload can be controlled theoretically,but during the machining,assembly and working process of the press,the traditional structure has many problems,so it is necessary to optimize the structure of the hydraulic overload device.It is aimed to improve the design of the mechanical structure of the hydraulic overload device of the mechanical multi-point closed press in the text.The most reasonable design structure has been put forward.The shortcomings in the traditional structure have been solved.The structural characteristics of the optimal structure has been used to reduce the cost.
