Description
Technical field
The invention belongs to mining drilling tool processing technology field, more particularly to a kind of processing technology of monoblock type Three-edged drill stem.
Background technology
Drilling rod is one of main equipment of oilfield prospecting developing engineering and mining, and to the drilling mining of oil gas vital effect is played.With the intensification of drilling depth, the difficulty of probing is increasing, common API drilling rods can not deep oil well and ultra-deep oil well mining demand, petroleum industry and mining need high intensity, high torque, anti-thorn to leak the drilling rod of contour performance.At present the standard technology of common standard drilling rod is individually processed to be formed using drilling rod with joint, then by drilling rod and joint friction welding, then weld seam is carried out into subsequent treatment, such as austenitizing, high tempering etc..The processing technology of this kind of drilling rod is complicated, and process equipment has high demands.But cause material structure difference larger at the drilling rod and weld of this Split type welded, cause to be welded as overall most weak part, be so easy to accident in use.Also there are the processing technology of some stem formulas, such as a kind of processing technology of integral drill rod in the patent publication of Patent No. ZL200810025356.5 now；It is characterized in that：The tool joint of the integral drill rod and drill pipe body are carried out direct-connected using box and pin, and drill pipe body structure thicker, tool joint outer wall and inwall are monoblock type structure thicker, and its processing technology adopts the following steps：A) pin end heating in medium frequency, first time jumping-up thickeies；B) heating in medium frequency, second jumping-up thickeies；C) polish；D) heating in medium frequency, third time jumping-up thickeies；E) heating in medium frequency, the 4th time jumping-up thickeies；F) turn round workpiece；G) box end heating in medium frequency, first time jumping-up thickeies；H) heating in medium frequency, second jumping-up thickeies；I) polish；J) heating in medium frequency, third time jumping-up thickeies；K) reconditioning；L) screw thread is processed.Explanation simply very general in the file jumping-up processing method of simple stem is disclosed, this processing for belonging to more conventional is taken precautions against, and especially data parameters in process are not open.More problems to be measured can not be solved so during reality processing.Simultaneously.Secondary processing technology adopts three jumping-ups, but in actual use, we need not simultaneously increase so many wall thickness, and in addition three jumping-ups expend material very much.
The content of the invention
The problem to be solved in the present invention is that the standard technology of existing common standard drilling rod is adopted drilling rod and joint friction welding, is welded as overall most weak part；Monoblock type processing method is too simple, it is impossible to solve the problems, such as reality processing.
In order to solve above-mentioned technical problem, the present invention provides following scheme：The processing technology of monoblock type Three-edged drill stem, including step A：Inspection Rhizoma Sparganii steel pipe parameters；Step B：By Rhizoma Sparganii steel pipe blanking to the length for needing；Step C：Rhizoma Sparganii steel pipe after blanking is fixed using fixture, makes the Rhizoma Sparganii steel pipe after blanking keep the state opened；Step D：The pin end and box end of Rhizoma Sparganii steel pipe carries out first time heating with induction heating equipment of medium frequency respectively, is uniformly heated to 1100 DEG C -1200 DEG C；Step E：The Rhizoma Sparganii steel pipe for heating is put into rapidly in finish forge equipment, starting automatic finish forge equipment carries out first time finish forge；Step F：The pin end and box end of Rhizoma Sparganii steel pipe carries out second heating with induction heating equipment of medium frequency respectively, is uniformly heated to 1100 DEG C -1200 DEG C；Step G：The Rhizoma Sparganii steel pipe Jing finish forges equipment for heating carries out second finish forge；Step H：The steel pipe at the good two ends of finish forge is carried out into overall modifier treatment；Step I：The effective straightener of three-edged steel after quenched carries out alignment；Step J：Lathe in machining screw thread is used, is tested with screw thread checking device；Step K：Nitrizing Treatment is carried out to tool joint part；Step L：Anti-twisting property selective examination is carried out with moment of torsion test device, by drilling rod mark, surface antirust treatment.Using above-mentioned processing technology, orderly processing can be can be carried out from the inspection of Rhizoma Sparganii steel pipe to last detection, the tool joint of the Three-edged drill stem processed by above-mentioned processing technology and the body of rod are the integral forms of identical material, are welded or mechanical connection form without any, avoid the generation of various defects, drilling rod integral rigidity is good, torsional strength is high, and the split type Three-edged drill stem than welding improves more than 30 percent.Because drilling rod is processed by same drilling rod special steel pipe through two ends finish forge, tool joint part structure is more accurate, again butt joint part carries out the Nitrizing Treatment of special process to drilling rod Jing after integrally quenched, the intensity and wearability of the so body of rod and blank area is greatly improved, and greatlys save the drilling rod consumption of user.By same steel pipe, the Jing two ends finish forge under the parcel of same straight line fixture is formed drilling rod, and drilling rod linearity is good, and the life-span is good, and pore-forming size is good, and gas sealing of hole difficulty is low.The temperature range of heating is clearly given in this processing technology, main in the process of whole integral drill rod is also most important data, because what the two ends of Rhizoma Sparganii steel pipe required machining for, the technique such as preheating, the finish forge at two ends can affect the institutional framework of whole Rhizoma Sparganii steel pipe.
Further, in step D, the pin end and box end of Rhizoma Sparganii steel pipe carry out first time heating with induction heating equipment of medium frequency respectively, are preferably heated to 1150 DEG C, it is ensured that the stability of the crystalline phase tissue of Rhizoma Sparganii steel pipe, while Rhizoma Sparganii steel pipe now also allows for shaping.
Further, in step F, the pin end and box end of Rhizoma Sparganii steel pipe carry out second heating with induction heating equipment of medium frequency respectively, are preferably heated to 1050 DEG C, it is ensured that the stability of the crystalline phase tissue of Rhizoma Sparganii steel pipe, while Rhizoma Sparganii steel pipe now also allows for shaping.
Further, in step D and step F, the pin end and box end of Rhizoma Sparganii steel pipe length heating respectively away from termination 220mm in heating process.Because this segment distance is used for shaped joint, so this part must be heated uniformly, while needing to adjust its crystalline phase institutional framework, it is ensured that the stability of joint.
