Abstract
The utility model discloses a kind of four-way junction of casing forging blank, comprise body, and the flange plate to be wholely set with body, described body is hollow cylinder, described flange plate is two and is separately positioned on the two ends of body, one of them flange plate is provided with annular projection, another flange plate is provided with the annular recess matched with annular projection, like this when stacking, adjacent annular projection matches with annular recess, owing to being provided with annular recess and annular projection, because flange plate end face is not smooth, like this when piling up, annular projection can snap in annular recess, can prevent flange plate end face from can not slide, convenient transport, improve Security during transport.
Description
Technical field
The utility model relates to a kind of forging, and more particularly, it relates to a kind of four-way junction of casing forging blank.
Background technique
Forging is that metal is applied in pressure, moulds the shape of requirement or the object of suitable compressive force by plastic deformation.This strength realizes typically by use iron hammer or pressure, and forging process has built exquisite granular structure, and improves the physical attribute of metal.
In oil exploration equipment, usually need to use four-way junction of casing body and some connections are carried out to petroleum pipeline, and when producing this four-way junction of casing head body, often need first to carry out that preliminary working is shaping becomes four-way junction of casing forging blank, and then carry out being finish-machined to into finished product, four-way junction of casing forging blank comprises middle body and is arranged on the flange plate for being processed into flange at body two ends, but in actual production process, place and the accurately machined place of preliminary working are not set together, the generation of preliminary working needs to be transported to finishing factory by manpower and materials and manufactures further after production completes, in order to convenient transportation, often four-way junction of casing forging is piled up and transport together, existing flange plate is owing to being just stacked, the end face of adjacent flange plate is all smooth, owing to not arranging any stop member between two flange plate of such contact, when flange plate is stacked, easily slide between adjacent flanges dish, and then cause four-way junction of casing forging blank generation landing, reduce reliability during transport.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of face abutted due to adjacent flanges dish that prevents to be smooth and cause flange plate that the four-way junction of casing forging blank slided occurs when transporting.
For achieving the above object, the utility model adopts following technological scheme, a kind of four-way junction of casing forging blank, comprise body, and the flange plate to be wholely set with body, described body is hollow cylinder, and described flange plate is two and is separately positioned on the two ends of body, one of them flange plate is provided with annular projection, and another flange plate is provided with the annular recess matched with annular projection.
Preferably, described annular projection shape of cross section is trapezoidal.
Preferably, the circumferential surface of described flange plate caves inward and forms the locating slot of ring-type.
Preferably, described flange plate and body joint are provided with chamfering.
Preferably, be provided with pipeline in described body, described annular projection is two, and two annular projections are separately positioned on flange plate near the position of pipeline and the position away from pipeline.
The utility model hinge structure is compared to be had: by flange plate at one end arranges ring-type projection, the flange plate of the other end arranges annular recess, like this when stacking, adjacent annular projection matches with annular recess, owing to being provided with annular recess and annular projection, because flange plate end face is not smooth, like this when piling up, annular projection can snap in annular recess, can prevent flange plate end face from can not slide, convenient transport, improves Security during transport.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model four-way junction of casing forging blank embodiment.
In figure: 1, body; 2, flange plate; 3, annular projection; 4, chamfering; 5, annular recess; 6, locating slot; 7, pipeline.
Embodiment
Below in conjunction with accompanying drawing, the utility model four-way junction of casing forging blank embodiment is described further.
A kind of four-way junction of casing forging blank, comprise body 1, and the flange plate 2 to be wholely set with body 1, body 1 is hollow cylinder, is provided with pipeline 7 in body 1, and flange plate 2 is two and is separately positioned on the two ends of body 1, in order to the stress reduced between flange plate 2 and body 1 is concentrated, be provided with chamfering 4 in flange plate 2 and body 1 joint, add man-hour, then the size turning having more needs go out different holes and other features.
A flange plate 2 is provided with annular projection 3 wherein, another flange plate 2 is provided with the annular recess 5 for inserting for annular projection 3, when piling up like this, annular projection 3/ annular recess 5 on a upper flange plate 2 snaps in annular projection 3/ annular recess 5 on next flange plate 2, by coordinating of annular projection 3 and annular recess 5, when piling up, can prevent adjacent flange plate 2 from sliding, the four-way junction of casing forging blank piled up is caused to slide, and then generation four-way junction of casing forging slides when transporting, when causing transport, four-way junction of casing forging slides, and then cause four-way junction of casing forging to be toppled over, cause production accident, when carrying out fine finishing, annular projection 3 turning can be fallen, as for annular recess 5, can turning fall, or, blocked with the seal ring of same size, such annular recess 5 not only can play the effect of location.
In order to make the structure of annular projection 3 more stable, be trapezoidal at annular projection 3 shape of cross section, annular projection 3 is arranged to trapezoidal, can prevent annular projection 3 from fractureing from root, and then cause locate failure, in order to make the locating effect of annular projection 3 better, annular projection 3 is two, be separately positioned on flange plate 2 near the position of pipeline 7 and the position away from pipeline 7, annular projection 3 near pipeline 7 is 10 ~ 20mm apart from pipeline 7, same, away from the annular projection 3 of pipeline 7, edge 10 ~ the 20mm of distance flange plate 2, annular projection 3 pairs of annular recess 5 can be facilitated like this to position, and can conveniently seal ring be arranged in annular recess 5, increase the sealing effect of flange plate 2.
Conveniently from laterally packing to flange plate 2, cave inward at the circumferential surface of flange plate 2 and form the locating slot 6 of ring-type, the height of locating slot 6 is 1/1 to two/3rd of flange plate 2 height, the degree of depth of locating slot 6 is 1 ~ 2mm, when packing to four-way junction of casing forging blank, strap can be placed in locating slot 6, prevent strap from sliding, improve the reliability of four-way junction of casing forging when transporting, locating slot 6 is when fine finishing, also its turning can be fallen, not affect follow-up use.
The above is only preferred implementation of the present utility model; protection domain of the present utility model is also not only confined to above-described embodiment; all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model; should be understood that; for those skilled in the art; do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
