一、概况预应力短向圆孔板是我厂的主要产品,过去我车间采用机组流水作业线生产,虽然机械化程度并不低,生产效率也较高,但是,工艺上还存在不少问题。例如,脱模区几乎全靠手工操作,劳动强度大;支拆模板工序繁琐;模板维修量大;模板和构件的运送全靠桥式吊车,吊次频繁,等等。针对这些问题,我们遵照毛主席关于“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,在厂党委的领导下,组成了“三结合”工艺改革小组,决心改变这种落后面貌。我们首先进行了调查研究,听取具有生产实践经验的老工人的意
I. Overview Prestressed short-to-round hole plates are the main products of our factory. In the past, our workshops used the unit flow line to produce. Although the mechanization degree is not low and the production efficiency is high, there are still many problems in the process. For example, the demoulding zone is almost entirely manual operation, and the labor intensity is large; the demolding template process is cumbersome; the template maintenance volume is large; the transportation of the template and the components depends on the bridge crane, and the hoisting is frequent, and so on. In response to these problems, we followed the guidance of Chairman Mao on “Mankind has to constantly sum up experience, discover, invent, create, and advance.” Under the leadership of the factory party committee, we formed a “three-in-one” process. The reform team is determined to change this backwardness. We first conducted investigations and studies and listened to old workers with experience in production practices.
