高铁铆工李学忠的“传奇匠心”

2018-04-30 17:01:11    新华网

37年铆工生涯的“高光时刻”发生在2009年夏天:工人们第一次组装CRH380BL列车,由于缺乏经验导致多处误差,最大误差约30毫米。来自德国西门子的技术主管盖特纳现场勘验认为,这次组装成型失败,材料报废。“报废就意味着200多万元打了水漂。”李学忠不信这个邪,带着周晶辉等徒弟硬是废寝忘食地攻坚了近72小时,反复加温、试制、冷却,最后硬是“变废为宝”,盖特纳惊讶地竖起了大拇指。

轨道列车生产的“江湖”上,高速动车车体侧墙和车顶对接是公认的难题,两个大型部件组装时必须保证零误差,不少“高手”在这里犯了难。老办法费时费力效率低,李学忠领着团队仅用2个月就设计制作出车顶串动装置,原来4个人10分钟的工作,现在1个人2分钟就能搞定。

李学忠有一些有趣的绰号,如“生产百度”“攻关旺铺”。为啥用搜索引擎命名?铝车体车间里与生产相关的任何细微工艺细节他无所不晓,有谁犯难了,到李学忠这里“搜索”一下准没错。为啥叫“旺铺”?几年来,他带领车间班组开展各类技术攻关千余项,节约生产成本六七百万元,是大家眼里的攻关点子旺铺,开张以来从没得过“差评”。

人过花甲,本是颐养天年的开始,但李学忠依然炙手可热。他透露,曾有外省企业给出5倍于返聘工资的高薪,但他还是选择留在自己干了大半辈子的工厂和车间,“我是长客的工人,企业培养了我,我要继续在长客发挥余热”。
