The utility model design feature is also, the triangle pipe ring end face employing friction-welding structure form of the annular end face that described large step cylinder forms and the Rhizoma Sparganii body of rod.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the weld part of this practical tool joint is combined by small stair cylinder and large step cylinder, the diameter of large step cylinder is consistent with the triangular outline inscribed circle diameter of Rhizoma Sparganii circular arc ribbed drill pipe, and the diameter of small stair cylinder is consistent with the endoporus triangle inscribed circle diameter of Rhizoma Sparganii circular arc ribbed drill pipe; So neither affect in joint and body of rod friction welding process and relatively rotate, played again positioning action, in phase mutual friction, produce a large amount of heat makes rod end reach thermoplasticity state simultaneously, during rapid upset, because small stair circle is embraced in rod end crimp, increased the torsional property of joint and the body of rod.
2, the weld part of the utility model tool joint adopts small stair cylinder and large step cylinder combination, met on the one hand the cross section requirement of friction welding, guaranteed the uniformity of finished product tool joint and body of rod size, also guarantee on the other hand the straightness accuracy of the inside and outside joint screw threads in two ends, improved the crudy of drilling rod.
3, the connected mode of the utility model tool joint can meet the welding of unlike material and the body of rod, has saved welding material simultaneously.
4, the utility model tool joint has improved the welding quality of drilling rod, avoids welding the defects such as bubble, and welding reproducibility is high, and joint is stable, and thermal deformation is less, has higher dimensional accuracy.
5, the manufacturing procedure before the welding such as original triangle drilling rod finished edge, interlocking has been avoided in the utility model tool joint, has reduced manufacturing cost, can carry out dissimilar metal joint welding, consumed power and other welding methods be in a ratio of its 1/5～1/20.
4, novel Rhizoma Sparganii circular arc ribbed drill pipe structure has improved the manufacturability of the production of product, simple to operate, without skilled grasp, by automatic feeding clamping mechanism, can realize unmanned running.
