[0019] The utility model is described in detail according to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, the oil drill pipe joint strengthening treatment device includes a base 1, a quenching treatment unit and a cooling treatment unit.

[0021] The upper surface of the base 1 is provided with an X-axis horizontal drive mechanism, above which a processing box 6 is provided. The processing box 6 is provided with a suspended support plate 9, and the upper surface of the suspended support plate 9 is provided with a plurality of stepped positioning slots 11 distributed in a matrix.

[0022] The quenching unit comprises a first lifting base 5 and a heating element assembly disposed on the lower surface of the first lifting base 1 and configured to correspond one-to-one with the stepped positioning slots 11. In this embodiment, the outer edge of the lower surface of the first lifting base 1 is larger than the upper edge of the treatment box 6. The heating element assembly comprises a heating base, a central heating rod 12 connected to the heating base, and a spiral heating element 8 arranged concentrically with the central heating rod 12. The centerlines of the central heating rod 12 and the spiral heating element 8 respectively coincide with the centerlines of the stepped positioning slots 11. The diameter of the central heating rod 12 is smaller than the inner diameter of the oil drill pipe joint 10, while the inner diameter of the spiral heating element 8 is larger than the inner diameter of the oil drill pipe joint 10.

[0023] The cooling unit comprises a hollow second lift base 7 and a spray assembly 14 mounted on its lower surface, corresponding one-to-one with the stepped positioning slots 11. Below the treatment box 6, multiple legs 4 are connected to the X-axis horizontal drive mechanism. One leg 4 communicates with the interior of the treatment box 6 and has a water inlet 3 on its sidewall. Another leg 4 also communicates with the interior of the treatment box 6 and has a water outlet 18 on its sidewall. The top surface of the second lift base 7 is equipped with a water inlet 13 connected to a water supply line. The nozzles of each spray assembly 14 communicate with the interior of the second lift base 7.

[0024] The X-axis horizontal drive mechanism includes a horizontal screw 17 supported on the base 1, a sliding sleeve 2 provided on the horizontal screw 17, a horizontal guide bar 16 supported on the base 1 and parallel to the horizontal screw 17, and a guide cylinder 15 provided on the horizontal guide bar 16. The support legs 4 at the bottom of the processing box 6 are connected and fixed to the sliding sleeve 2 and the guide cylinder 15.

[0025] Working principle:

[0026] 1. Fix each oil drill pipe joint 10 in the stepped positioning groove 11 of the suspended support plate 9.

[0027] 2. The horizontal drive mechanism drives the processing box 6 to the bottom of the quenching treatment unit. The first lifting seat 5 descends and is buckled onto the top of the processing box 6. The central heating rod 12 of each heating element assembly is inserted into the corresponding oil drill pipe joint 10, and the spiral heating body 8 of the heating element assembly is wrapped around the outer circumference of the oil drill pipe joint 10. Under the dual action of the central heating rod 12 and the spiral heating body 8, the inside and outside of the oil drill pipe joint 10 are quickly heated, accelerating the heating speed.

[0028] 3. After heating is completed, the quenching treatment unit is reset, and the horizontal drive mechanism drives the treatment box 6 to the bottom of the cooling treatment unit. The second lifting seat 7 descends and is buckled on the top of the treatment box 6. The oil drill pipe joints 10 are sprayed point-to-point for cooling through each spray assembly 14. At the same time, water is quickly injected into the treatment box 6 through the water inlet 3 of the support leg 4 until the oil drill pipe joint 10 is submerged. The spray cooling stops, and the water outlet 18 of the other support leg 4 drains water outward. During the continuous operation of the water inlet 3 and the water outlet 18, the water level is kept unchanged and the water temperature is within the cooling temperature range.

[0029] 4. After cooling, drain the cooling water in the processing box 6 through the water outlet 18 and take out the workpiece.

[0030] The above detailed description of the embodiments of the present invention is intended to be a preferred embodiment of the present invention and should not be construed as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the present invention shall still fall within the scope of this patent.
