Problems solved by technology

[0002] In the past, large-scale seat rings used upper and lower double-ring plate structures. Although the process method of this structure is simple, the material cost is relatively high. Poor, welding deformation is difficult to control, and the foundation plate is processed after welding to close the through hole. Although this method has high precision, the equipment processing cost is high and the production cycle is long, which is not conducive to cost reduction and efficiency increase

Embodiment Construction

[0026] Such as figure 1 As shown, the present invention provides a reasonable and simple process flow, low cost, short production cycle, easy to control welding deformation and can be used for assembly and welding process of large split seat ring with single upper ring on the base plate. The specific implementation of the present invention The way is:

[0027] A method for assembling and welding a single upper ring type large-scale split seat ring with a base plate, comprising the following steps:

[0028] 1) The upper rib plate 1, the upper joint plate 4, and the base plate 8 are cut according to the requirements, the peripheral plate 2 and the inner wall plate 3 are cut according to the requirements, then flattened, and then rolled and formed, and the upper ring plate 5 is cut according to the requirements material, and then flattened, the flatness is 1mm ~ 3mm;

[0029] 2) Sub-assembly: draw the assembly line of the upper rib 1, peripheral panel 2, inner wall 3, and upper...

Abstract

The invention relates to an erecting welding technological method for a single-upper-ring type large segmented stand ring with sole plates. A sole plate positioning template and positioning pipes are used for precise positioning; and after splice welding of a lower guide plate, fixed guide vane mounting holes are perforated in a matched mode, and then fixed guide vanes are inserted. The key process problems of stand ring welding deformation, sole plate assembly positioning, sole plate combining through hole processing cost, the production cycle and the like are solved through an auxiliary lower ring, the sole plate positioning templates and the positioning pipes, and the production cost and the production cycle are reduced. According to the stand ring manufactured through the technological method, the problems of assembly positioning, the production cost, welding deformation and the like are effectively solved, and construction site installation requirements are met; the subsequent production cycle and processing cost are greatly reduced, economy and practicability are both considered, and the purposes of lowering cost and improving effects are achieved.
