J11-100型单柱固定台压力机是由营口锻压机床厂设计、我省制造的产品,该机在结构上存在一些缺陷。如:原机无过载保护装置,因而超负荷时连杆就弯曲卡死;前后衬套寿命短并容易松出,飞轮在工作中窜动;曲轴后端双键离合器油盒漏油等,严重地影响了生产。1977年我厂在大修此设备时,对该机进行了针对性的改造。改进后,机床经过五年多的生产考验,效果良好。一、加装过载保护装置针对超负荷就会发生曲轴和连杆等主要零件损坏的情况,我们加装了过载保护装置。根据压力机结构及该机用于切边工艺行程较短的情况,采用了薄板剪
J11-100-type single-column fixed press is designed by Yingkou Forging Machine Tool Plant, manufactured in our province, the aircraft there are some structural defects. Such as: the original machine without overload protection device, so overload when the connecting rod bent stuck; before and after the bushing short life and easy to loose, flywheel in the work of the movement; double-clutch crankshaft rear oil box oil spill, serious Affected the production. In 1977, when I plant overhaul this equipment, the aircraft was targeted transformation. Improvement, the machine after more than five years of production test, the effect is good. First, the installation of overload protection device For overload will occur crankshaft and connecting rod and other major parts of the damage, we installed an overload protection device. According to press structure and the machine used for trimming process shorter stroke, the use of sheet metal shears
