我厂200公斤空气锤在使用中经常发生这样的毛病:在空运转提锤状态时锤头上提的高度不够。这个毛病一方面使锤头的行程减小而大大降低了打击能量;另一方面锤头位置较低,锤头和下砧块间的空间小,停锻时锤头下落速度快,生产不安全。这个毛病经几次修理都未能解决。为了保证正常进行生产,我组工人同志们通过对毛主席著作的学习,遵照毛主席关于“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”的教导,下定决心要把这台锤的“病”治好。通过分析研究,找出锤头上提高度不够的原因是旋阀系统中逆止阀的封闭作用不良,在提锤时锤杆活塞下端的压缩空
Our factory 200 kilograms of air hammer in the use of such problems often occur in the hammer when the status of hammer lift mention is not enough height. This problem on the one hand to reduce the stroke of the hammer and greatly reduce the impact energy; the other hand, the hammer position is lower, the space between the hammer and the lower anvil is small, when the stop forging hammer drop fast, unsafe production . This problem can not be solved by several repairs. In order to ensure the normal production, through the study of Chairman Mao’s works, the comrades in our group of comrades, in accordance with Chairman Mao’s teaching on “mankind always sums up experiences, finds out, finds inventions, creates them and advances them” Determined to put this hammer “disease” cured. Through the analysis and research to find out the improvement of the hammerhead is not enough because of the check valve system in the closed valve system is poor, the hammer at the bottom of the piston rod when the compressed air
