Device for adjusting large thick-wall deformed end socket

The utility model discloses a device for adjusting a large thick-wall deformed end socket, which is characterized in that firstly, the diameter of the end socket is mechanically adjusted by a hydraulic jack and an extension bar, so that the boundary dimension of the end socket meets the drawing requirement, then a cross-shaped process tie bar is additionally welded, and the end socket is subjected to in-furnace stress relief heat treatment to eliminate internal stress generated by mechanical adjustment; the shape and size stability of the end socket is ensured. After the deformed end socket is adjusted through the end socket adjusting device, the shape and the size of the end socket all meet the requirements of drawings, meanwhile, the mechanical performance of the end socket is not affected, and the manufacturing quality of the end socket is guaranteed. 本实用新型公开一种调整大型厚壁变形封头的装置，首先用液压千斤顶和加长杆对封头直径进行机械调整，使封头外形尺寸符合图纸要求，然后加焊十字工艺拉筋，并对封头进行炉内消应力热处理，消除机械调整产生的内应力，保证封头形状尺寸稳定。采用本实用新型对变形的封头进行调整后，封头形状尺寸全部符合图纸要求，同时封头机械性能不受影响
