Abstract
Disclosed is a connecting head of a sucker rod applied in a pumping well, comprising a screwed head and a square rib arranged on the screwed head. The utility model is characterized in that the position of the square rib on the clamping spanner is designed to be cylindrical; four platforms are projected on four corresponding tangency points of the circular section; the plane of the platform is in parallel with the tangent of the tangency point and arc is arranged between the platform and the cylinder for transition; the structure of the is integrated with the sucker rod. The connecting head of the sucker rod is easy to be forged with even and continuous quenching so that the fatigue resistance intensity of the sucker rod is enhanced and the service life is improved.
Description
One, technical field
This use is novel to relate to the rod connector that a kind of pumpingh well is used.
Two, background technology
The rod connector that present pumpingh well is used, the cross section of beating the spanner place is a square, the process of forging its shape be one by circle to square process, distortion is violent, the fiber of metal cuts off, cause often fracture herein in application, serious accident takes place, increase workover cost, rate when influencing oil well production causes very big economic loss.
Three, summary of the invention
The purpose of this utility model is the defective that overcomes former rod connector, newly designs a kind of rod connector.Technical solutions of the utility model are to realize in the following manner:
Newly-designed rod connector is made up of screw thread head and the card spanner side rib of establishing thereon, it is characterized in that rib place, card spanner side is made as cylindrical, 4 platforms are protruded at the place at 4 point of contacts of circular section symmetry, the plane of platform is parallel with the tangent line at point of contact, be arc transition between platform and the cylinder, its structure and sucker rod are made as one.
The utility model adds convex surface reinforcing rib shape at card spanner position by the original square cylinder that is made as, and has increased cross-sectional area, is square 1.4 times, has overcome the defective that stress is concentrated, and has strengthened the intensity of antifatigue, improves endurance life more than 2 times.This exterior cylindrical surfaces is quenched and can be easy to accomplish evenly continuously, overcome fully square in quenching process the arris place reach hardening heat earlier and its place does not reach hardening heat and makes the inconsistent shortcoming of quenching intensity.
Four, description of drawings
Fig. 1 is the structural front view of rod connector.
Fig. 2 be among Fig. 1 A-A to sectional view
Five, embodiment
The utility model is made up of screw thread head and the card spanner side rib of establishing thereon, it is characterized in that rib place, card spanner side is made as cylindrical, 4 platforms are protruded at the place at 4 point of contacts of circular section symmetry, the plane of platform is parallel with the tangent line at point of contact, be arc transition between platform and the cylinder, its structure and sucker rod are made as one.This rod connector is forged easily, and uniform quenching is continuous, has strengthened the rod connector fatigue resistance, has improved application life.
