Problems solved by technology

However, after the bending machine bends the wall plate, the curvature of the wall plate will rebound. After the angle iron is welded, the additional stress brought by welding will make the deformation of the piece more serious.
The pre-bending of the bending machine and the orthopedics after welding are cumbersome and the accuracy is not easy to guarantee, which brings troubles to the processing of steel lining pieces

Embodiment 1

[0030] The segment 13 has been bent by a bending machine. At this time, the bent piece wallboard is hoisted to the collet 3, and the height of the hydraulic cylinder 7 is adjusted so that the collet 3 driven by the swing support frame 2 contacts with the fragment 13, and the collet on the split collet 4 The guide rod is inserted in cooperation with the guide holes on the main body support frame 1 and the movable chuck 3 . At this time, the positioning bolt 6 is tightened so that the rear side of the fragment is in close contact with the bottom of the movable chuck 3, and the front side of the fragment is in close contact with the positioning bolt 6, and then the fastening bolt 5 is tightened to complete the fragmentation in the fixture. on the positioning. At this time, the horizontal angle iron 9 with a thickness of 10mm and the longitudinal angle iron 10 with a thickness of 6mm are respectively positioned and spot-welded on the inner lining plate, and then all welds are wel...

Embodiment 2

[0033] Segment 13 is just a flat plate cut by the shearing machine, without bending by the bending machine. At this time, the plate is hoisted to the chuck part of the fixture, and the height of the hydraulic cylinder 7 is adjusted so that the movable chuck 3 driven by the swing support frame 2 is in contact with the sub-piece 13, and the guide rod on the split chuck 4 is connected to the movable bracket. Insert it into the guide hole on it. After the positioning of the slices on the fixture is completed, the hydraulic cylinder 7 is pressurized, and the hydraulic cylinder pushes the slider 8 to move down, driving the pointer 11 connected to the slider to move down, and the scale 12 records the downward movement, and then releases the hydraulic pressure cylinder pressure, so that the reading of scale 12 meets the requirements after the rebound, and the bending of the wall plate is completed. Then carry out the welding of the transverse angle iron 9 with a thickness of 10mm and...

Abstract

The invention discloses a containment steel lining fragment forming clamp which comprises a main body support frame and a clamping head structure for clamping a fragment and positioned on the main body support frame and is characterized in that at least one reciprocating sliding block connected with a driver is arranged on the main body support frame at different heights of the direction perpendicular to the main body support frame; a swinging support frame is connected onto the sliding block; the other end of the swinging support frame is connected with the clamping head structure. According to the invention, a bent wallboard is rapidly clamped, radian of the wallboard can be conveniently adjusted, spot welding positioning of angle iron on the outer side of the wallboard can be conveniently realized, and a hydraulic device can conveniently carry out correction after a steel lining fragment is welded, so that the clamping time and the correcting time after welding the angle iron are greatly shortened, the labor intensity is alleviated, and the correcting accuracy is improved.

Description

technical field [0001] The invention relates to a fast tooling for welding forming and an integrated post-welding orthopedic fixture for nuclear power plant containment shell steel lining slices. Background technique [0002] The steel lining fragments of nuclear power plants are an important part of the containment shell. The containment shell is welded by hundreds of pieces of steel lining slices, prefabricated in the workshop, and then hoisted to the corresponding parts of the containment shell for welding. It requires high dimensional accuracy. However, the area of ​​a single piece is large and the arc is small. The current processing method is to first bend the pieced panel structure with a bending machine, and then manually spot-weld the angle iron required on the outside of the panel, and then weld it again. All welds. After welding, the monolithic panels are mechanically and flame straightened. However, after the bending machine bends the wall plate, the curvature...
