Abstract

The utility model aims at providing an one shot forming's stem comprises a steel pipe one shot forming, and screw thread, board mouth and the middle limbers at all both ends only need one shot forming, no longer do the structure of secondary operation or hot upset post -treatment both ends screw thread. The drilling rod comprises a steel pipe, can satisfy the production requirement of the drilling rod within the 15 -800mm, comparatively simple of structure, easily manufacturing only needs to confirm the length of required drilling rod, one shot forming can, light in weight, good, the simple structure of concentricity.

Description

One-time formed integral type drilling rod
Technical field
The utility model relates to the drill pipe art that the multiple rig such as electric rock drill, down-the-hole drill, hydraulic drill rig, geological drilling rig, digging-free rig uses, and is specially one-time formed integral type drilling rod.
Background technology
Existing drilling rod application widely, as rock mining, geological drilling rig etc., along with the reinforcement of exploitation difficulty, also progressively promotes the technical requirements of drilling rod.
Existing drilling rod is by the round steel at two ends, through holes drilled through, milling side, car clamping, cutting thread, then is welded on middle steel pipe.
Existing drilling rod is comparatively heavy from first aspect in sum, and because two ends round steel is processed into water hole, screw thread, Fang Bankou, the some residual material after processing is too heavy, and after being welded into drilling rod, overall weight is too heavy; Second aspect materials are many, and the weight of two ends steel substantially exceeds the weight of interlude tubing, and machining period is longer, complex process; The third aspect, owing to being welded by three joints, concentricity is low, easily wave, easily broken and use life short.
Summary of the invention
The purpose of this utility model is to provide a kind of one-time formed stem, be made up of a steel pipe one-shot forming, the limbers of the screw thread at all two ends, plate mouth and centre, only needs one-shot forming, no longer does the structure of secondary operations or hot upsetting aft-loaded airfoil two ends screw thread.
To achieve these goals, the present invention takes following technical scheme
One-time formed integral type drilling rod, it comprises: internal thread 1, external screw thread 2, stripper mouth 3, outlet pass 4, drill pipe body 5.
One end of described drill pipe body 5 inside is provided with internal thread 1, and the described other end arranges external screw thread 2, and described middle limbers 4 is arranged on the inside of drill pipe body 5 to top by end, and described stripper mouth 3 is arranged on the nearly two ends in drill pipe body 5.
The screw thread that described drill pipe body 5 adopts is canine tooth, square tooth, wave mode screw thread and taper thread.
Drill pipe body 5 in sum can be round, triangular form, square and six squares.
Beneficial effect of the present invention
1, drilling rod is made up of a steel tube place, can meet the production requirement of the drilling rod within 15-800mm;
2, structure comparatively simple, is easy to processing and manufacturing, only the length of required drilling rod need be determined, one-shot forming;
3, good economy performance, the life-span is long, lightweight, good concentricity, structure are simple.
Accompanying drawing explanation
1, Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The purpose of this utility model is to provide a kind of one-time formed stem, be made up of a steel pipe one-shot forming, the limbers of the screw thread at all two ends, plate mouth and centre, only needs one-shot forming, no longer does the structure of secondary operations or hot upsetting aft-loaded airfoil two ends screw thread.
To achieve these goals, the present invention takes following technical scheme
One-time formed integral type drilling rod, it comprises: internal thread 1, external screw thread 2, stripper mouth 3, outlet pass 4, drill pipe body 5.
One end of described drill pipe body 5 inside is provided with internal thread 1, and the described other end arranges external screw thread 2, and described middle limbers 4 is arranged on the inside of drill pipe body 5 to top by end, and described stripper mouth 3 is arranged on the nearly two ends in drill pipe body 5.
The screw thread that drill pipe body 5 adopts in sum is canine tooth, square tooth, wave mode screw thread and taper thread.
Drill pipe body 5 in sum can be round, triangular form, square and six squares.
Below in conjunction with accompanying drawing, the utility model is further illustrated
Shown in Fig. 1,1-internal thread, 2-external screw thread, 3-stripper mouth, 4-outlet pass, 5-drill pipe body.
One end of described drill pipe body 5 inside is provided with internal thread 1, and the described other end arranges external screw thread 2, and described middle limbers 4 is arranged on the inside of drill pipe body 5 to top by end, and described stripper mouth 3 is arranged on the nearly two ends in drill pipe body 5.
The screw thread that described drill pipe body 5 adopts is canine tooth, square tooth, wave mode screw thread and taper thread.
Drill pipe body 5 in sum can be round, triangular form, square and six squares.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
