0 前言 我厂为第二汽车制造厂生产的康明斯B系列活塞销,产品标准规定:每只销子装机前的清洗度为2毫克。即销子的杂质含量小于等于2毫克。上述标准给活塞销的成品清洗提出了较严的要求。给我们提出了新的课题。目前国产活塞销对清洗度有要求者甚少,用一般的清洗方法即可满足成品技术要求。而要达到2毫克这样高的清洗度标准。采用传统的清洗方法已无法满足用户要求。我们曾用人工刷洗三次的办法,另加一次串洗,虽然可达到清洁度的标准,但工人劳动强度大。工作条件恶劣,劳动效率低下,而且清洗出合格品的稳定性较差,随机性大。
0 Foreword Our factory is the Cummins B series piston pin manufactured by the second automobile factory. The product standard stipulates that the cleaning degree before each machine is installed is 2 milligrams. That the pin impurity content of less than or equal to 2 mg. The above standards to the piston pin finished cleaning put forward more stringent requirements. Give us a new topic. At present, domestic-made piston pins have little requirement on the degree of cleaning, and the general cleaning method can meet the technical requirements of finished products. To achieve such a high level of 2 mg cleaning standards. The traditional cleaning method has been unable to meet user requirements. We have used manual brushing three times, plus a string wash, although the cleanliness standards can be achieved, but the workers labor-intensive. Poor working conditions, low labor efficiency, and the poor stability of cleaning qualified products, large randomness.
