在装焊锅炉锅筒、筒形化工容器时,大多采用自动焊接。但在装焊最后一个管板(封头)时,由于自动焊机头伸不进筒身内,因此终接内环缝多用手工焊接。采用终接内环缝自动焊装置,便可实现了自动焊接,能提高产品质量和生产效率。现将该装置的结构介绍如下: 底板11靠三个压板10定位,用螺栓夹紧,压在锅筒管板上,使其中心与锅筒中心一致。轴4焊在底板上。滚筒2套在滚动轴承5上,可以在轴4上自由转动。套筒下面焊有夹板,自动焊机头装在夹板上。采用自动焊焊接终接内环缝时,锅筒转动,
In the welding boiler drum, cylindrical chemical containers, most of the automatic welding. However, when welding the last tube plate (head), the welding of the inner ring seam is mostly done by manual welding because the head of the automatic welding machine does not enter the barrel body. With the termination of the inner seam automatic welding device, we can achieve automatic welding, can improve product quality and production efficiency. Now the structure of the device are introduced as follows: The bottom plate 11 is positioned by three pressure plates 10, which are clamped with bolts and pressed onto the drum tube plate so that the center thereof coincides with the center of the drum. Shaft 4 welded on the floor. Roller 2 sets in the rolling bearing 5, can be freely rotated on the shaft 4. Welded plywood below the sleeve, automatic welding head mounted on the splint. The use of automatic welding to terminate the seam seam, the drum rotation,
