我厂铸件系单件小批生产,形状复杂,大小不一,大者重达十几吨,小者一公斤左右,工艺要求复杂。因此,长期以来,既没有实现机械化流水作业,也没有采用高效能的机械设备,处于繁重的手工劳动状态。为了解放笨重工序的繁重体力劳动,我们自行设计制造了由圆盘给料机和电动滚筒回转皮带机组成的送砂机,直接将型砂送入砂箱之内,收到较好的效果,深受工人欢迎。这套给砂机构的组成如图1所示。
I plant a small batch of small pieces of casting production, complex shapes, sizes, the heavier than a dozen tons, the smaller one kilogram, the process requires complex. Therefore, for a long time, neither mechanized assembly line operation nor high-performance mechanical equipment has been put into operation, which is in a state of heavy manual labor. In order to relieve heavy manual labor, we designed and manufactured a sand feeder consisting of a disc feeder and a motor-driven rotary belt conveyor to directly send the molding sand into the flask to achieve good results. The depth Welcome by workers. This set of sand bodies as shown in Figure 1.
