Description
Technical field
The utility model relates to drill pipe thickening field, specifically a kind of thickening monoblock type no-dig technique drilling rod is used to be added from cooling
Thick formed punch.
Background technique
Thickening is one of important procedure of drilling rod production.Make outer diameter of steel pipes increase or internal diameter reduce or outer diameter increase it is same
When internal diameter reduce, be that the wall thickness of steel pipe increases in a word, such process just named thickening.Thickening usually carries out at high temperature, is one
A hot forging production process.Thickening formed punch is the important tool for thickening production process, it is in axial high pressure, axial high stretching, impact
It works under the environment such as load, a small amount of radial load, high abrasion, lubricant burn into high temperature, rapid cooling, by biggish cold and hot
Alternate load effect.Therefore, thickening formed punch is also a kind of consumables.Common formed punch ontology failure mode has: in biggish friendship
It under varying load, tensile load, Radial Loads, is attenuated or breaks, generate bending deformation or fracture；When cooling down not in time,
Formed punch ontology is annealed, and the decline of load ability to function is resisted, and is easy to produce abrasion, deformation, the even failure such as cracking.Reasonably
Formed punch ontology is cooling, is the important measures for improving formed punch ontology service life.Monoblock type small dimension no-dig technique drilling rod is thickeied, is thickeied
Shaping length is long, and formed punch ontology and high-temperature steel tube time of contact are long, and reasonable cooling is particularly important.
In the prior art, by the way of mainly being sprayed using external longitudinal spray or circumferentially to the cooling for thickening formed punch.To non-
For the formed punch ontology for excavating small dimension Integral upset formula drilling rod, thickening punch diameter is small, and this type of cooling cooling is insufficient,
Often there is high annealing in formed punch ontology, and bearing capacity decline situations such as deformation, even fracture failure often occurs, uses the longevity
It orders shorter.
Utility model content
Problem to be solved in the utility model is to provide a kind of certainly cooling thickening formed punch of thickening monoblock type no-dig technique drilling rod,
The thickening formed punch has internal cooling structure, uses simultaneously with outside cooling, but the cooling of formed punch ontology is more abundant, improves punching
The service life of head ontology.
To solve the above problems, taking following technical scheme:
The thickening monoblock type no-dig technique drilling rod of the utility model includes formed punch ontology with formed punch is thickeied from cooling, the formed punch sheet
Body is formed by path section and the concentric integrally connected of major diameter section.Its main feature is that the axial location of the formed punch ontology has through its overall length
Through-hole, the corresponding through-hole one end of path section is connected with atomizer.
Further improvement of the utility model scheme be further include extension bar, the extension bar and the outer end of formed punch ontology major diameter section are in
Threaded sealing fit.There is centre bore in one end that the extension bar corresponds to formed punch ontology, which is connected with the through-hole of formed punch ontology
It is logical.There is radial hole on the extension bar, which is connected with centre bore, and the outer end of radial hole is connected with water filling spray head.
Above scheme is taken, is had the advantage that
The thickening monoblock type no-dig technique drilling rod of the utility model, which is used from cooling, thickeies formed punch, including formed punch ontology, the formed punch
Ontology is formed by path section and the concentric integrally connected of major diameter section；The axial location of the formed punch ontology has through the logical of its overall length
Hole, the corresponding through-hole one end of path section are connected with atomizer.In use, cooling water is corresponding logical from formed punch ontology major diameter section
The injection of hole one end, cooling water reach atomizer by formed punch body through-holes, and atomizer exists cooling water atomization, the water of atomization
In steel pipe under high temperature action, become vapor row Xiang great Qi.The longitudinally or circumferentially constant situation of spraying cooling mode outside original
Under, which increases internal cooling, keeps the cooling of formed punch ontology more abundant, improves formed punch ontology service life.
Further, it is directed to the structure of formed punch ontology and extension bar combination, utilizes centre bore and the formed punch ontology of extension bar
Through-hole connection, and imported cooling water in formed punch body through-holes by radial hole and water filling spray head, it is formed internal cooling.With it is original
External spraying cooling combine, can be improved the composite structure thickening formed punch service life.
Detailed description of the invention
Fig. 1 is that the thickening monoblock type no-dig technique drilling rod of the utility model is used from the cooling structural schematic diagram for thickening formed punch (in fact
Apply example one)；
Fig. 2 is that the thickening monoblock type no-dig technique drilling rod of the utility model is used from the cooling structural schematic diagram for thickening formed punch (in fact
Apply example two)；
Fig. 3 be in Fig. 2 A-A to view profile.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
Embodiment one
As shown in Figure 1, the thickening monoblock type no-dig technique drilling rod of the utility model includes formed punch sheet with from the cooling formed punch that thickeies
Body 1, the formed punch ontology 1 are formed by path section and the concentric integrally connected of major diameter section.The axial location of the formed punch ontology 1, which has, to be run through
The through-hole 2 of its overall length, corresponding 2 one end of through-hole of path section are connected with atomizer 3.
In use, cooling water is injected from corresponding 2 one end of through-hole of 1 major diameter section of formed punch ontology, cooling water passes through formed punch sheet
1 through-hole 2 of body reaches atomizer 3, and cooling water atomization, the water of atomization under high temperature action, are become water in steel pipe by atomizer 3
Steam arranges Xiang great Qi.In the case that longitudinally or circumferentially spraying cooling mode is constant outside original, which increases inside
