新型悬挂式管板焊机机头研制

Development of Hanging Tube-sheet Welder Head

悬挂式管板焊机在大直径换热器的制造和维修上具有很大优势,但目前国产悬挂式焊机技术与国外相比还有一定差距。为解决焊机机头悬挂使用条件下焊枪精确定位与调整、机头轻量化等技术难题,开发了一种新型悬挂式管板焊机。该焊机采用胀管器胀管定位方式以及新型的焊枪轴向、径向调整结构,具有结构紧凑、功能完善、工作可靠和焊接质量好等特点。该焊机机头已经产品化并规范应用。

The hanging tube-sheet welder has great advantages in fabrication and repair for big diameter heat exchangers. But there is a certain gap between domestic welders and abroad welders.To solve the problems of precise positioning and adjusting of welding torch under hanging conditions and head lightweight, developed a new type of hanging tube-sheet welder. The welder is located by hydrauhc pipe expander, and it has the new structure of axis and radial adjusting for welding torch. The welder is compact, perfect in functions and reliable, with good quality of welding. The welder head has already been industrialized and applied standardized.
