一、前言我厂S195型柴油机生产批量较大,但铸工车间生产面积小,机械化程度较低,劳动强度大,工装数量有限。由于工装需用大量的金属材料和加工时间,加之型板、合箱两次定位,影响到铸件的质量,因此,铸件的供不应求,成了我厂完成任务的关键。为适应生产发展的需要,生产更多的优质铸件,必须采用新技术, First, the foreword Our factory S195 type diesel engine produces the batches to be large, but the casting workshop production area is small, the mechanization degree is lower, the labor intensity is big, the tooling quantity is limited. As the tooling requires a lot of metal materials and processing time, combined with the template, the box positioning twice, affecting the quality of the castings, therefore, the casting in short supply, became my plant to complete the task of the key. In order to meet the needs of production development, production of more high-quality castings, we must adopt new technologies,
