缫丝机上的小(竹或),是轴对称零件,其材料为ZL102铸造合金。这类零件,表面质量要求高,批量大。图l是其中之一种,这个零件净重0.29公斤,毛坯重量0.45公斤,轮廊尺寸φ180×70,形状复杂,厚薄不均,最薄处仅1.5mm,除中间的孔处及端面,其余均不机加工,外面八条筋要求抛光后绕蚕丝无挂丝现象。所以要求表面光滑,无缺陷。零件的工作环境潮湿并有弱碱水蒸气,要求有较好的抗蚀性能。
Reeling machines on the small (bamboo or), is the axis of symmetry, the material is ZL102 casting alloy. Such parts, surface quality requirements, large quantities. Figure l is one of them, the parts net weight 0.29 kg, rough weight 0.45 kg, wheel size φ180 × 70, the shape of complex, uneven thickness, the thinnest at only 1.5mm, except for the middle of the hole and the end, the rest were Not machined, outside the eight bars after polishing no silk hanging around the silk phenomenon. So require a smooth surface, no defects. Parts of the working environment moist and weak alkali water vapor, require good corrosion resistance.
