本精压机是济南第二机床厂于1965年12月试制成功的新产品(见图)。它是一种通用型的压印精压压力机。主要是使用在要求小的工作行程、大的冲压力的各种工艺过程中。其主要特点是:力量大,刚性好,精度高与速度快。因此广泛用于冷精压,压印、波形冲压及冲压后的校平等工序。本精压机采用上传动的精构型式,床身是篇跌粗合式精构,速杆采用受拉型式,滑块在下死点位置时有一段保压时简。各摩擦部位根
The press is the second Jinan Machine Tool Plant in December 1965 successful trial of new products (see photo). It is a universal stamping press. Mainly used in a small work schedule, a large stamping force of the various processes. Its main features are: power, rigidity, high precision and speed. Therefore widely used in cold coining, stamping, stamping and stamping after the school level and so on. The press machine uses the fine structure of the transmission type, the body is a chapter down article rough fine structure, the lever with tension type, when the slider at the bottom dead center for a period of dwell time. The friction parts of the root
