我厂生产的机油滤清器滤网(见图1)数量较大。过去一直用模钻的办法加工孔,劳动强度大,易断钻头,工效低。在学习兄弟单位先进经验的基础上,经过“三结合”小组的反复试验、改进,将模钻改成自动冲孔,每次冲两排,共15孔,带料(或条料)自动送进,实践效果良好。 I plant the oil filter screen (see Figure 1) a larger number. In the past, the hole has been drilled with a diamond, which is labor-intensive, easily broken, and low work efficiency. On the basis of learning advanced experience of brother unit, after repeated experiments by the “triple combination” group, the mold was changed into automatic punching, punched two rows at a time for a total of 15 holes, and the material (or strip) was automatically sent Progressive, practical effect is good.
