两种新型高速锤匈牙利自1962年起开始发展高速锤,到目前为止,已经完成了两个系列的设计。第一个系列采用氮气作为工作介质,以液压系统进行再压缩。如图1所示,气缸充满了氮气,其压力为P_0=120大气压。活塞杆R为中空形。气缸固定在机架内。机架和砧座A连成一个整体,悬挂在橡胶弹簧S_1S_2上。打击后,在油缸C的活塞和拉杆R_1的作用下,工作缸的活塞回到其原始位置。图2所示为NEK-8型
Two new high-speed hammers Hungary has been developing high-speed hammers since 1962 and has so far completed two series of designs. The first series uses nitrogen as the working medium and is recompressed with a hydraulic system. As shown in Figure 1, the cylinder is filled with nitrogen at a pressure of P_0 = 120 atm. The piston rod R is hollow. Cylinder fixed in the rack. The frame is connected with the anvil A as a whole and is suspended on the rubber spring S_1S_2. After the blow, the piston of the cylinder C and the rod R_1 will return the piston of the working cylinder to its original position. Figure 2 shows the NEK-8 type
