铸钢车间接到厂部下达的生产浇铸机链板的任务,要求在一个月内生产出5000个链板毛坯(如图1所示)。每个链板毛坯重约4kg。合计约20t。从重量上来说,完成这一任务对一个20多人的铸钢车间不成问题,但根据车间现有条件,接常规生产方法(两箱造型),仅砂箱和生产场地不足这两项的限制就无法完成生产任务。因为考虑成品率,平均每天应至 Casting shop received the factory issued the production of casting machine chain plate task, requiring production within a month 5000 chain blank (Figure 1). Each chain blank weighs about 4kg. Total about 20t. In terms of weight, this task is not a problem for a cast steel plant of more than 20 persons. However, according to the existing conditions of the workshop, the conventional production methods (two-box modeling), the restriction of only the sand box and the shortage of production sites Can not complete the production task. Because of the yield, the average daily should be
