一九七二年我们学习了兄弟单位型砂风力压送的先进生产技术,在党委领导下,经过半年多的日夜奋战,于一九七三年实现了型砂风力压送生产线。一九七六年又完成了铸件落箱、输送生产线。今年又实现了新砂气力输送线。这样,活塞环铸造砂处理和运输基本实现了机械化。工人从笨重的体力劳动中解放出来。一、概述铸型浇注后,用小车推至震动出箱机上,震动落箱,(如图3)砂箱由空车带回。活塞环、浇冒口、砂子用皮带运输机送入两层筛砂机。浇冒口、活塞环在筛上分开,旧砂落入提
In 1972, we studied the advanced production technology of the sand blowing unit of the brother unit, and under the leadership of the party committee, after more than six months of fighting day and night, we achieved the production line of sand pressure-fed sand production in 1973. In 1976, it completed the casting boxes, conveying production lines. This year has also achieved a new sand pneumatic transmission line. In this way, piston ring casting sand handling and transportation basically mechanized. Workers are relieved from bulky manual labor. First, an overview After pouring the mold, with a car pushed to shake out of the box machine, shake box, (as shown in Figure 3) sand box brought back by the empty car. Piston ring, Riser, sand belt conveyor into the two-screen sand machine. Riser, piston rings separated in the sieve, the old sand into the mention
