为了解决叶轮和轮毂的拉孔精度问题,我们用土办法设计制造了图示的简易半自动多用双面拉床。实践证明,这种设备结构简单,容易制造,操作方便,安全可靠。保证了加工质量,可提高效率两倍,现介绍如下。一、结构(见图示) 该拉床具有一般液压机床的特点。它是由床身支撑架1、齿轮泵33、主油缸13、两个副油缸6和21、活塞杆39、活塞环14、活塞15、三位四通电磁阀27、溢流阀28、分配阀29、密封件11和12以及辅助设施油箱30、管道25和
In order to solve the impeller and hub of the hole accuracy problem, we use the soil design and manufacture of a simple schematic semi-automatic double-sided broaching machine. Practice has proved that this device is simple in structure, easy to manufacture, easy to operate, safe and reliable. To ensure the quality of processing, can improve the efficiency of double, are presented below. First, the structure (see illustration) The broaching machine has the characteristics of a general hydraulic machine. It consists of a bed support 1, a gear pump 33, a master cylinder 13, two slave cylinders 6 and 21, a piston rod 39, a piston ring 14, a piston 15, a three-position solenoid valve 27, a relief valve 28, Valve 29, seals 11 and 12 and auxiliary facility tank 30, pipe 25 and
