近年来,山东省一些县农机修造厂广大职工全心全意为贫下中农服务,为普及大寨县贡献力量,认真贯彻“平战结合、又修又造、目前以修为主”的方针,在开展增产节约,修旧利废工作中,对铸铁冷焊、断裂曲轴焊接等方面作了大量工作,积累了不少经验。它不但能使内燃动力机械复活,有力地支援农业生产,同时也解决了配件供应不足的问题,并且为国家节省了钢铁,为社队节省了资金,为早日实现农业机械化加快了进程。黄县农机修造厂在复新断裂曲轴的实践中,摸出了曲轴的断裂规律:曲轴往往是在曲柄、轴颈(连杆轴颈上从油孔处斜断)或曲柄与轴颈相接处断裂;制订了合理的焊接工艺,
In recent years, a large number of employees in some county-level agricultural machinery repair factories in Shandong Province wholeheartedly served the poor and under-aged peasants, made contributions to the popularization of Dazhai County, conscientiously implemented the principle of “combining peace with war, building with repair, and taking cultivation as the mainstay” , Repair and old Lee waste work, a lot of work on cast iron cold welding, fracture crankshaft welding, has accumulated a lot of experience. It can not only revitalize the internal combustion engine, effectively support agricultural production, but also solve the problem of insufficient supply of spare parts. It also saves the country the steel, saves funds for the communes and brigades, and accelerates the process of agricultural mechanization at an early date. Huang County Agricultural Machinery Repair Factory in the practice of the Fuso broken crankshaft, out of the crankshaft rupture of the law: the crankshaft is often in the crank, journal (connecting rod journal oblique from the hole) or crank and journal phase Department rupture; developed a reasonable welding process,
