我厂生产大型柴油机球铁曲轴,大断面曲轴冒口过去采用气焊切除。在切除冒口处的曲轴端部位置经加工后,常发现内孔边缘有内裂纹,影响曲轴内在质量。为迅速解决此弊病,在厂党委领导下组织三结合人员,发扬“独立自主、自力更生”的革命精神,在几个月努力下,自行制出一台圆锯床。经过几年来的生产实践,效果良好,解决了大断面球铁曲轴冒口切割的质量问题。
I plant a large diesel engine ductile iron crankshaft, large cross-section crankshaft riser used in the past gas welding cut. In the removal of riser at the end of the crankshaft after processing, often found within the inner edge of the inner crack, affecting the internal quality of the crankshaft. In order to solve this problem promptly, under the leadership of the factory party committees, the three combined personnel were employed to carry forward the revolutionary spirit of “independence and self-reliance” and, within a few months of hard work, formulated a circular sawing machine. After several years of production practice, the effect is good, to solve the large-section nodular iron riser cutting quality problems.
