Problems solved by technology

[0002] At present, the spherical plate cannot be processed directly, and it is usually processed after cutting. However, this method can neither guarantee good processing accuracy and good processing line shape, but also adds a lot of difficulties to the subsequent assembly and welding construction. Serious Affected the construction and schedule of production
Moreover, this method of processing requires a very high technical level of the operator, and the processing time is long and the labor intensity is high.
The processing technology is difficult, the spherical shape cannot be guaranteed, and the productivity is low. For parts with strict spherical shape requirements, the precision requirements cannot be met

Abstract

The invention discloses a machining tool for a spherical plate. The tool comprises an upper mold and a lower mold, wherein the lower mold comprises a lower columnar structure defined through welding connection of sides of at least three lower rib plates and a seat plate arranged at the bottom of the lower columnar structure; a machining concave end surface is arranged at the top of the lower columnar structure, and the curve of the machining concave end surface is consistent with the radian of a curved surface of the to-be-machined spherical plate; the upper mold comprises an upper columnar structure defined through welding connection of sides of at least three upper rib plates and a top plate arranged at the top of the upper columnar structure; and a machining convex end surface is arranged at the lower end of the upper columnar structure and is matched with the machining concave end surface in radian. The smooth degree of the appearance of the plate can be guaranteed with the tool, assembly, electric welding and polishing in following processes can be reduced, the manufacturing period of the spherical plate can be shortened, and the manufacturing cost of the spherical plate can be saved.

Description
