Effect), the pressing plate lower surface is detachably provided with the second limiting device, described after retainer ring described in step C completes fitting
Pressing plate is matched at the top of core, and the top of the convex portion and non-convex portion is matched by second limiting device and core
It closes and fixes, locating effect is more preferable, while in the welding process, preferably reduces the deformation of workpiece.
As a preferred solution of the present invention, first limiting device and the second limiting device are ring structure, annular
Ground carries out the positioning to convex portion and non-convex portion, and locating effect is more preferable, while in the welding process, preferably reducing
The deformation of workpiece.
As a preferred solution of the present invention, in step A, the convex portion and the mating rear progress repair of non-convex portion,
It is further ensured that the locating effect of convex portion and non-convex portion, while being compared to the mode of single high request, repair is more
Save the cost.
As a preferred solution of the present invention, in step C, the convex portion and non-convex portion are completed after installing, in institute
It states the gap between convex portion and non-convex portion and carries out tack welding and the first limiting device and the cooperation of the second limiting device, make
General orientation effect is more preferable, promotes the effect of welding.
As a preferred solution of the present invention, in step D, after being welded, de-stress is gone to the annular metal plate shell of formation,
The quality of toroidal shell finally after processing is completed is promoted, the possibility that deformation occurs is reduced.
As a preferred solution of the present invention, in step D, X-ray detection is carried out to annular metal plate shell after destressing, and right
Poor weld carries out repair welding, is further ensured that the quality of toroidal shell finally after processing is completed.
As a preferred solution of the present invention, it in step D, when being welded, alternately welds with the weld seam of core formed symmetrical,
In the welding process, the deformation of workpiece is preferably reduced.
Compared with prior art, beneficial effects of the present invention:
It is save the cost, high in machining efficiency and the convex portion of several monomers and non-convex portion can be welded into ring junction
It is configured to the annular metal plate shell needed.
