我车间的一吨汽锤配上操作机后,锻工的劳动强度显著降低,生产效率不断提高。可是汽锤机的劳动强度却增加了。为了解决这个矛盾,我们试制了液压随动阀(图1),用它来代替原来汽锤上的手柄(图2)。把随动阀的缸 With one ton of hammer attached to the operating machine in my workshop, the work intensity of the forging worker is significantly reduced, and the production efficiency is continuously improved. However, Hammer machine labor intensity has increased. In order to solve this contradiction, we made a hydraulic follow-up valve (Figure 1), which used to replace the original handle on the hammer (Figure 2). The cylinder follow the valve
