Abstract

本发明涉及机械设备的工艺孔封口技术，尤其是用于汽车涡轮增压器的工艺孔封口技术。本发明的技术方案是：一种工艺孔封口技术，包括壳体和堵片，所述壳体和堵片均采用球墨铸铁，先将堵片准确放置于封口处，然后通过滚压式封口技术对封口缝隙进行360°全封闭。采用上述技术方案，产品在任何条件下都不会出现松动及漏气现象，有效的提高了增压器的使用可靠性。

Description

一种工艺孔封口技术
技术领域
本发明涉及机械设备的工艺孔封口技术，尤其是用于汽车涡轮增压器的工艺孔封口技术。
背景技术
现有技术中，涡轮增压器工艺孔封口采用的是点压式封口技术，由于压点与堵片接触面积很小，这样在热胀冷缩及剧烈震动的情况下，容易产生松动及漏气现象，给产品质量带来不良影响。
发明内容
本发明的目的是提供一种不会使产品产生松动和漏气的封口技术。
为实现上述目的，本发明的技术方案是：一种工艺孔封口技术，包括壳体和堵片，所述壳体和堵片均采用球墨铸铁，先将堵片准确放置于封口处，然后通过滚压式封口技术对封口缝隙进行360°全封闭。
采用上述技术方案，产品在任何条件下都不会出现松动及漏气现象，有效的提高了增压器的使用可靠性。
具体实施方式
 一种工艺孔封口技术，包括壳体和堵片，所述壳体和堵片均采用球墨铸铁，先将堵片准确放置于封口处，然后通过滚压式封口技术对封口缝隙进行360°全封闭。
