Abstract
The utility model discloses a tube mould for large-scale centrifugal nodular cast iron applied in industries of oil field, natural gas and steel. A left ring body (1), a right ring body (2) and a middle ring body (3) are integrally welded together by weld lines (4). The utility model adopts the manufacturing process that the metal materials of 21 CrMo10 are separately forged into cylinder type and then are welded for entirety, thereby reducing the difficulty on entire forging, decreasing manufacturing cost, saving raw material and meeting requirements of various quality technical descriptions.
Description
Technical field:
The utility model relates to a kind of large centrifugal ductile iron pipe pipe mold that is applied to oil field, natural gas and steel industry.
Background technology:
The production of large centrifugal ductile iron pipe pipe mold is a great problem of mold manufacturing industry always.Now mostly adopt the method for solid forging, the one, appearance and size φ 1500mm is bigger, and the 2nd, weight is heavier, adopts the also very difficult forging molding of forcing press more than large-scale ten thousand tons, main at present by from external import with by domestic indivedual business monopolies, restricting the development of this industry always.
The utility model content: the utility model has overcome the big drawback of former pipe mold solid forging difficulty, provides to reduce production costs, a kind of large centrifugal ductile iron pipe pipe mold that saves material.Its left ring body 1, right ring body 2 and middle ring body 3 are in the same place by weld seam 4 integral solder.Because the utility model adopted the 21CrMo10 metal material to forge cartridge type respectively, the production technology of integral solder has reduced the difficulty of solid forging, has reduced production cost, has saved raw material, has satisfied every quality and technical index requirement.
Description of drawings:
Fig. 1 is a main cutaway view of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment;
Shown in Figure 2 as Fig. 1, utilize domestic existing large press to forge left ring body 1, right ring body 2 and middle ring body 3 respectively, when forging, can forge the right-hand member of left ring body 1, the left end of right ring body 2 and the cut 5 at middle ring body 3 two ends respectively, and weld together with weld seam 4.In the axially levelling earlier of when welding, keep the glacing flatness of whole cylindrical shell, spot welding is then selected technical indicators such as rational environment temperature, speed of welding and welding material to weld again and is got final product.
Claims (2)
1. a large centrifugal ductile iron pipe pipe mold is characterized in that left ring body (1), right ring body (2) and middle ring body (3) are by weld seam (4) integral solder together.
2. a kind of large centrifugal ductile iron pipe pipe mold according to claim 1 is characterized in that the left end of the right-hand member of left ring body (1), right ring body (2) and middle ring body (3) two ends all are cut (5).
