我厂铸铁车间1983年购买一台Z1410A型顶箱震压造型机,用于东风四型内燃机车的缸套造型。生产实践证明,该机生产率高,铸型质量好,是目前国内生产大型铸件较理想的造型机。但另一方面,设备维修率高,噪声较大。该机震击司气阀和转台转臂油缓冲器以及立柱经常发生故障,如不加以改造,就不能正常使用。根据故障分析可知,解决司气阀掉螺栓头卡震和转臂不能精确定位的问题,是保证生产正常进行的关键。我们经过三年多的努力,圆满地完成了改造任务。
I plant cast iron workshop in 1983 to buy a Z1410A top box vibration molding machine for the Dongfeng four-cylinder diesel locomotive modeling. Production practice has proved that the aircraft high productivity, good quality castings, is currently the ideal production of large castings machine. But on the other hand, equipment maintenance rate, noise. The machine Shock Division gas valve and turret arm buffer and column often malfunction, if not to be modified, it can not be used normally. According to the analysis of the failure, we can see that the key problem of ensuring the normal production is to solve the problem that the valve of the gas valve is out of position with the bolt head and the boom can not be precisely positioned. After more than three years of hard work, we successfully completed the task of reconstruction.
