近年来,我们对使用国产中小型机械压力机最多的仪表、照相机、电影放映机、复印机、电表及电器开关等行业一些骨干企业进行了调查,结合河南、甘肃、上海、西安等省市一些工厂对中小型机械压力机进行技术改造设计所遇到的一些问题,颇值得深思。现仅就其存在的问题及技术改造对策谈一些意见。 存在的问题 In recent years, we have conducted surveys on some key enterprises in industries such as meters, cameras, movie projectors, photocopiers, electric meters and electrical switches that use the largest number of domestic small and medium mechanical presses. Combined with some factories in Henan, Gansu, Shanghai and Xi’an, Small and medium-sized mechanical presses for technical transformation of the design of some of the problems encountered, it is worth pondering. Now only talk about some of its existing problems and technical transformation measures. Problems
