Abstract
The present invention relates to a manufacturing method for a thin-walled stainless steel pipe fitting with a bending part, and is used for the production of the thin-walled stainless steel pipe fittings such as elbows and overhead pieces, etc. The pipe fitting is divided into a socket part (1) of two ends connected with a tube and a central bending part (2). The socket part (1) is produced by adopting the pressure-expansion forming of the thin-walled stainless steel pipe fitting. The bending part (2) is produced by adopting precision casting technique of stainless steel. The socket part (1) and the bending part (2) are combined and welded into a whole by welding, thereby reducing the dimensions of the pipe fittings and having low cost and beautiful appearance.
Description
(1) technical field:
The present invention relates to a kind of manufacture method that has curvature thin wall stainless steel pipe fittings, be used for the manufacturing of thin-walled stainless steel tube link.
(2) background technique:
Thin-walled stainless steel tube has become a big focus of domestic feedwater piping development.At present as its pipe fitting that has a curved section as: its manufacture methodes such as elbow, gap bridge have following two kinds:
1, press-working method
With the thin-wall stainless steel is raw material, makes by crooked and swelling pressure technology.Fold not taking place when guaranteeing the thin-wall stainless steel canal curvature, requires big bending curvature radius.Produced like this elbow and gap bridge size are very big, and profile is not attractive in appearance.
2, microcast process
Adopt the precision stainless steel casting process to make blank, adopt the machining manufacturing then.Though the elbow of this manufactured and gap bridge have solved the big problem of product size, product weight is bigger, and adopts machining cost higher.
(3) summary of the invention:
The objective of the invention is a kind of manufacture method that has curvature thin wall stainless steel pipe fittings that will provide new, it is little to make it size, and cost is low, and beautiful shape.
The object of the present invention is achieved like this: the stainless steel pipe that elbow and gap bridge etc. are had a curved section is divided into the socket joint part and the middle curved section at the two ends that are connected with pipe.Socket joint partly adopts thin-wall stainless steel as raw material, by the pressure processing manufactured.Curved section adopts the manufacturing of precision stainless steel casting process.Socket joint part and middle curved section assembly welding with two ends is integral at last.
The present invention is owing to adopted the middle curved section of precision casting manufactured, and radius of curvature can be very little.Adopt the socket joint part of press-working method again, save machining with thin-wall stainless steel pipe manufacturer two ends.Though many one welding processs owing to be circumferential weld, can adopt full-automatic argon arc welding machine to weld, and have both guaranteed welding quality, guarantee high productivity again.Therefore, owing to the manufacturing process that adopts precision casting, pressure processing and welding to combine, integrate the advantage of various manufacturing process, thereby it is little to obtain size, does not need the product of machining.Make product cost low, beautiful shape.
The invention will be further described below by drawings and Examples.
(4) description of drawings:
Accompanying drawing is the schematic representation of manufacture method of elbow.
Among the figure: 1, socket joint part 2, curved section
(5) embodiment:
Socket joint part (1) adopts thin-wall stainless steel as raw material, makes by swelling pressure shaping equal pressure processing technology.Curved section (2) adopts the manufacturing of precision stainless steel casting technique.Socket joint part (1) and middle curved section (2) with two ends adopts full-automatic argon arc welding machine integrally welded then.Because the curved section integral precision casting of passing a bridge is had any problem, and then it is divided into two sections from the centre and carries out precision casting respectively, assembly welding is integral again.
Claims (1)
1. a manufacture method that has curvature thin wall stainless steel pipe fittings is characterized in that: the socket joint part (1) and the middle curved section (2) that pipe fitting are divided into the two ends that are connected with pipe; Socket joint part (1) adopts thin-wall stainless steel as raw material, by the pressure processing manufactured; Curved section (2) adopts the manufacturing of precision stainless steel casting process, and socket joint part (1) and middle curved section (2) assembly welding with two ends is integral at last.
