钢水包塞杆芯在生产中耗费极大,由于内孔M20螺纹不小心磕碰,还经常粘钢,使M20 螺纹扣损坏,致使长1300mm、外径36mm的塞杆芯经常报废,大大增加了维修加工量、材料浪费及资金消耗。据统计每年塞杆芯耗费圆钢3.2t,价值6千多元。为解决上述问题,对塞杆芯进行了如下图所示的改进。把塞杆芯分为两段,用螺纹联接。每天只要准备几件短杆,在工作前检查,发现短杆内孔M20螺纹及外径损坏不能使用立即换掉。短杆制造容易,
Due to the inadvertent bump M20 thread bump, but often stick steel, M20 threaded buckle damage, resulting in long 1300mm, 36mm diameter piston rod core often scrapped, greatly increased the maintenance Processing volume, material waste and capital consumption. According to the statistics, the rod core consumes round steel 3.2t, worth more than 6,000 yuan. In order to solve the above problem, the piston rod core as shown in the following improvements. The rod core is divided into two sections, with threaded connections. As long as the preparation of a few short pieces of a day, check before work and found that the short hole M20 thread diameter and diameter damage can not be replaced immediately replaced. Short rod easy to manufacture,
