The invention discloses a manufacturing method of an advancing jack, which is characterized in that a liquid through hole is opened after a cylinder barrel is subjected to finish machining, so that scrap iron generated by the finish machining of the cylinder barrel is prevented from entering a liquid through pipe, the subsequent cleaning difficulty is reduced, and the possibility that the scrap iron is remained in a whole hydraulic system to cause the problems of scratching, blocking and the like is reduced. Compared with the prior art, the cylinder barrel cleaning time is shortened to 8 min from original 10 min, the cleaning efficiency is improved by 20%, the product unqualified repair rate caused by cleanliness is reduced to 3.8% from original 30%, and the effect is improved by 87.3% compared with that of an original technology.
本发明公开了一种推移千斤顶的制造方法,在缸筒精加工后打通通液孔,避免缸筒精加工产生的铁屑进入通液管内,降低后续的清洗难度,减少铁屑残留在整个液压系统内从而引起划伤、堵塞等问题的可能,使用本发明所述的加工工艺,缸筒清洗时间由原有的10min降低为8min,清洗效率提升20%,由清洁度引起的产品不合格返修率由原来的30%降低为3.8%,效果较原有工艺提升了87.3%。
