近几年,东风朝柴公司进行了技术改造,通过对铸造、装配、试车生产线进行了技术改造,使生产能力、制造水平大为提高,达到了国内一流水平,但随之产生了一个新的矛盾,即柴油机生产的中间环节机械加工部分的设备日益老化,精度丧失,成为生产线上的“肠梗阻”。购置新设备或请原生产厂家大修都需要大量的资金,朝柴的决策者们决定聘请有关厂家和经验丰富的工程技术人员,对这些设备实施大修改造。首先在柴油机机体生产线上对三台6102机体缸孔镗床“动手术”,经过专家和工程技术人员的精心设计及维修人员的努力,这三台老设备均改造成功。他们在总结经验的基础上,又改造了4102机体线缸孔镗两台专机、上下钻孔四台专机和6102机体线前四台粗铣设备,均获圆满成功。
In recent years, Dongfeng Chaochai has carried out technological transformation. Through technological transformation of the casting, assembly and commissioning production lines, the production capacity and manufacturing level have been greatly improved, reaching the domestic first-class level, but a new one has emerged. Contradictions, that is, the middle part of the diesel engine production machinery processing parts of the equipment is increasingly aging, loss of precision, become the production line of “intestinal obstruction.” Purchasing new equipment or asking the original manufacturer to overhaul will require a lot of money. The decision makers of Zhachai decided to hire relevant manufacturers and experienced engineers and technicians to implement major modifications to these equipment. Firstly, in the diesel engine body production line, three sets of 6102 machine body boreholes were “operated”. After careful design of experts and engineers and the efforts of maintenance personnel, these three old equipments were successfully transformed. On the basis of summing up their experiences, they also reconstructed 4102 body line cylinder bores, two special planes, four special planes for drilling up and down, and four rough milling machines for the 6102 body line, all of which were successfully completed.
