Concave spherical surface structure is made by special grinding tool compression moulding, plasma cut blanking, then is welded in outside carbon steel spherical crown by molding
Convex surface.Easily there is hollowing phenomenon it is difficult to ensure that fitting closely for indent stainless steel and carbon steel spherical crown arcuate surface in the technology, causes to turn
It is dynamic dumb；In addition, the soldering opening of carbon steel and stainless steel is influenced by chemistry, electrochemical corrosion, lead to desoldering risk, so as to cause
Sliding surface rotates and anti-corrosion failure.
Utility model content
The purpose of this utility model is to provide a kind of combined type spherical crowns.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of combined type spherical crown, including curved surface stainless steel, anchor rib, casting metal；Wherein, the curved surface stainless steel is interior
Concave surface is welded with several anchor ribs, and the both ends of the curved surface stainless steel are equipped with the anchoring crotch for bending towards indent surface side；The song
Face stainless steel is located at anchor rib in casting metal.
The anchor rib in curved surface stainless steel inner concave, circumferentially arrange by array.
The combined type spherical crown has two kinds of single-curved surface, hyperboloid planforms；In single-curved surface spherical cap structure, curved surface is stainless
Steel is arranged along the single-curved surface of spherical crown；In hyperboloid spherical cap structure, two curved surface stainless steels are oppositely arranged along the hyperboloid of spherical crown.
The beneficial effects of the utility model：The interlayer of combined type spherical crown provided by the utility model is combined closely, and is avoided
The compound spherical crown of welded type has that hollowing phenomenon, soldering opening are influenced by chemistry, electrochemical corrosion, has good wear-resisting, resistance to
Corrosive nature.
