我厂是生产东风—12型手扶拖拉机的地方工厂,在毛主席关于理论问题的重要指示指引下,厂党委决定试制一批东风—30型四轮拖拉机,赶在春耕大忙季节之前下田试耕。在时间短、任务急的形势面前,模具生产便成了试制中的关键。针对上述情况,我们在研究推广低熔点合金薄板拉伸、弯曲模具的同时,又把低熔点合金模具应用到精密铸造上去。
I plant is the production of Dongfeng -12 walking tractor factory place, Chairman Mao on the theoretical issues under the guidance of an important guideline, the plant party decided to trial a group of Dongfeng -30 four-wheel tractor, catch the busy season in the spring before the trial of Shimoda . In a short time, the task of urgent situation, the mold has become the trial production of the key. In response to the above situation, we study the promotion of low melting point alloy sheet drawing, bending the mold at the same time, the low melting point alloy mold applied to the precision casting up.
