锻造液压机传动控制系统及元件试验研究是一项重点科研项目。它的目的是探求一种系统结构简单、性能良好、容易制造、便于标准化、使用维护方便,并易推广的新型传动控制系统。 1978年底对该项课题的试验室研究工作进行了鉴定,会议认为:所研制的内控锥式安全溢流伐、内控锥式方向伐、320kgf/cm~2乳化液介质的快速电磁伐(Ⅲ型),结构先进,性能优良,主要参数指标都达到了同类伐门部颁标准;由此而组成的系统大为简化,控制伐门集成化,动作配合协调,电控稳定,机组运转正常。这充分显示了上述成果的优越性,从而为实现锻液造压机传动系统的重大改革,提供了条件。该项试验室研究成果,已安排在一些工厂投入工业性生产考验,为满足大家需要,并在更大范围交流推广,本刊特组织发表以下三篇文章: 《锻造液压机传动控制系统试验研究》、《乳化液内控式锥伐设计试验》、《快速电磁伐的设计和试验》。本篇为第一篇,论述新研制的乳化液直接传动系统,特点是:采用高速轻型泵、电液内控式锥伐,尺寸精度和联动(与锻造操作机)自动控制装置;并介绍锻造液压机新的液压电气系统原理,系统调试,动态测试结果分析。
Forging hydraulic drive control systems and components of experimental research is a key research project. Its purpose is to seek a new type of transmission control system with simple system structure, good performance, easy manufacture, convenient standardization, convenient use and maintenance, and easy popularization. At the end of 1978, the laboratory research work of the subject was identified. The meeting concluded that: the developed internal control cone safety overflow logging, the internal control cone directional cutting, the rapid electromagnetic cutting of 320kgf / cm ~ 2 emulsion medium ), Advanced structure, excellent performance, the main parameters of the index have reached the same standards of cutting door Ministry; resulting system greatly simplified, control cutting door integration, coordinated action, electronic control and stability, the unit is operating normally. This fully shows the superiority of the above achievements, thus providing conditions for implementing major reforms in the hydraulic system of the forging press. The laboratory research results, has been scheduled in some factories into industrial production test, in order to meet everyone’s needs, and in a wider range of exchanges and promotion, the publication of the following three articles: “Forging hydraulic drive control system test research” , “Emulsion-controlled cone-cut design test”, “rapid electromagnetic cutting design and testing.” This article is the first one, discusses the newly developed emulsion direct drive system, characterized by: the use of high-speed light pump, electro-hydraulic internal control cone cutting, dimensional accuracy and linkage (with forging manipulator) automatic control device; and forging hydraulic press New hydraulic electrical system principle, system debugging, dynamic test results analysis.
