Abstract
The utility model discloses a kind of big specification drill pipe upsetting mold, it includes upper bolster and die shoe, the upper bolster is arranged at the surface of the die shoe, Upper Die-sleeve and lower die-sleeve are correspondingly installed on the upper bolster and die shoe, wherein, it is provided with the Upper Die-sleeve and clamps die cavity and upper thickening die cavity, lower clamping die cavity and lower thickening die cavity are correspondingly arranged in the lower die-sleeve, after Upper Die-sleeve and the lower die-sleeve matched moulds, the upper clamping die cavity and lower clamping die cavity form the clamping die cavity for clamping drilling rod, the upper thickening die cavity and lower thickening die cavity are formed for the thickening die cavity to drill pipe thickening.Above-mentioned big specification drill pipe upsetting mold eliminates original clamping mold and thickening mould, will clamp die cavity and thickening die cavity is fabricated directly on Upper Die-sleeve and lower die-sleeve.Mould structure is not only simplify, reduces processing cost；And on the premise of wall thickness intensity is met, it is more suitable for thickening big specification drilling rod.
Description
Technical field
The utility model belongs to drilling rod process technology, more particularly, to a kind of big specification drill pipe upsetting mold.
Background technology
Drilling rod maximum specification as defined in API is 6 5/8 ", in recent years, bigger specification drilling rod is in petroleum gas, particularly
Geology passes through aspect and obvious demand occurs, and big specification drilling rod is that following petroleum gas, geology pass through a development side of industry
To.
Thickening mould is the equipment commonly used in drilling rod process, and at present, existing thickening mould includes upper bolster mostly
And die shoe, Upper Die-sleeve and lower die-sleeve are correspondingly installed on the upper bolster and die shoe, be provided with the lower die-sleeve plus
Thick mould and upper clamping die, lower thickening model and lower clamping die are correspondingly installed in the lower die-sleeve.However as the increasing of drilling rod specification
Greatly, existing thickening mould can not meet the thickening process of big specification drilling rod.
Utility model content
The purpose of this utility model is to provide a kind of big specification drill pipe upsetting mold, and it has simple in construction and met big
The characteristics of specification drill pipe thickening, to solve above mentioned problem existing for drill pipe upsetting mold in the prior art.
To use following technical scheme up to this purpose, the utility model：
A kind of big specification drill pipe upsetting mold, it includes upper bolster and die shoe, and the upper bolster is arranged at the lower mould
The surface of seat, Upper Die-sleeve and lower die-sleeve are correspondingly installed on the upper bolster and die shoe, wherein, set in the Upper Die-sleeve
Have upper clamping die cavity and upper thickening die cavity, be correspondingly arranged on lower clamping die cavity and lower thickening die cavity in the lower die-sleeve, it is described on
After die sleeve and lower die-sleeve matched moulds, it is described it is upper clamp die cavity and the lower die cavity that clamps forms clamping die cavity for clamping drilling rod, it is described
Upper thickening die cavity and lower thickening die cavity are formed for the thickening die cavity to drill pipe thickening.
Especially, the upper bolster is fixed on hydraulic press moved cross beam, and it is flat that the die shoe is fixed on hydraulic press work
On platform.
Especially, the die shoe is fixed on the hydraulic press workbench by keyway and clamping screw.
Especially, the upper bolster is fixed on the hydraulic press moved cross beam by keyway and clamping screw.
Especially, the corner of the die shoe offers the open slot of U-typed, and the clamping screw is fixed on described open
In mouth groove.
The beneficial effects of the utility model are that the big specification drill pipe upsetting mold eliminates original compared with prior art
Clamping mold and thickening mould, by clamp die cavity and thicken die cavity be fabricated directly on Upper Die-sleeve and lower die-sleeve.Not only simplify
Mould structure, reduce processing cost；And on the premise of wall thickness intensity is met, it is more suitable for adding big specification drilling rod
It is thick.
Brief description of the drawings
Fig. 1 is the structural representation for the big specification drill pipe upsetting mold that the utility model embodiment 1 provides；
Fig. 2 is the top view of the lower die-sleeve for the big specification drill pipe upsetting mold that the utility model embodiment 1 provides.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of big specification drill pipe upsetting mold includes upper bolster 1 and lower mould
Seat 2, the upper bolster 1 is fixed on hydraulic press moved cross beam 3 by keyway and clamping screw, and the corner of the die shoe 2 is equal
The open slot 4 of U-typed is offered, the die shoe 2 is positioned by keyway on hydraulic press workbench 5, and passes through lock
Tight bolt is fixed on the hydraulic press workbench 5 through the open slot.
The upper bolster 1 is arranged at the surface of the die shoe 2, is correspondingly provided with the upper bolster 1 and die shoe 2
Upper Die-sleeve 6 and lower die-sleeve 7, it is provided with the Upper Die-sleeve 6 and clamps die cavity 8 and upper thickening die cavity 9, it is right in the lower die-sleeve 7
Lower clamping die cavity 10 and lower thickening die cavity 11 should be provided with, after Upper Die-sleeve 6 and lower die-sleeve 7 matched moulds, the upper clamping die cavity 8
The clamping die cavity for clamping drilling rod is formed with lower clamping die cavity 10, the upper thickening die cavity 9 and lower thickening die cavity 11 are formed and used
In the thickening die cavity to drill pipe thickening.
Above example simply elaborates general principle and characteristic of the present utility model, and the utility model is not by above-mentioned example
Limitation, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change and change, these changes
Change and change and both fall within claimed the scope of the utility model.The utility model requires protection scope will by appended right
Ask book and its equivalent thereof.
