Description

Technical Field

[0001] The present application relates to the technical field of drill rod quenching, and in particular to a drill rod quenching device. Background Art

[0002] The drill pipe body is heated to austenite for insulation before quenching, and then cooled by internal spraying and external showering. When the pipe body is cooled, it is easy to produce large deformation due to the superposition of thermal stress and phase change stress. The existing quenching equipment limits the heat treatment deformation of the pipe body by setting several groups of rotating rollers under the pipe body and pressing rollers on the pipe body. When the thick-walled pipe body is processed, the heat treatment deformation stress is large, and the pressure of the pressing roller is difficult to control in the actual production and processing process. A small pressure of the pressing roller cannot limit the deformation of the pipe body, and a large pressure of the pressing roller can easily cause indentations on the pipe body, causing damage to the pipe body or even scrapping. Summary of the invention

[0003] The present application provides a drill rod quenching device, aiming to solve the problem that the pressure of the pressure roller of the existing quenching device is difficult to regulate.

[0004] The present application provides a drill rod quenching device, comprising a machine tool body, a support frame is provided on one side of the machine tool body, the machine tool body is provided with a plurality of rotating roller groups for carrying the drill rod, each of the rotating roller groups comprises two rotating rollers, a plurality of correction mechanisms are hinged on one side of the support frame close to the machine tool body, and the correction mechanisms correspond to the rotating roller groups one by one;

[0005] The correction mechanism comprises a roller cylinder and a roller arm, one end of the roller cylinder is hinged to the support frame, one end of the roller cylinder away from the support frame is hinged to the roller arm, one end of the roller arm is hinged to the support frame, and one end of the roller arm away from the support frame is equipped with a roller;

[0006] A plurality of limiting mechanisms corresponding to the pressure roller arms are arranged between the machine tool body and the support frame, and the limiting mechanisms are used to limit the pressure roller arms to target positions.

[0007] Optionally, the limiting mechanism includes a support base, a support rod and a receiving block, the support base is mounted on the machine tool body near the rotating roller group, the support rod is fixedly mounted on the support base, the receiving block is mounted on one end of the support rod away from the support base, and the receiving block is used to receive and limit the pressure roller arm to be located at the target position.

[0008] Optionally, the receiving block is rotatably disposed on the support rod.

[0009] Optionally, the support base is slidably assembled on the machine tool body along a first direction, and a displacement component connected to the support base is provided on the machine tool body, and the displacement component is used to adjust the position of the support base.

[0010] Optionally, the displacement assembly includes a base block and a displacement screw, the base block is fixedly mounted on the machine tool body, and the base block is located in the first direction of the support base, the displacement screw thread passes through the base block, and one end of the displacement screw is rotatably connected to the support base.

[0012] Optionally, each of the pressure roller arms is provided with at least two pressure rollers.

[0013] Optionally, the two rotating rollers of the rotating roller group are arranged to overlap each other.

[0014] Beneficial effects:

[0015] The present application provides a drill pipe quenching device, which can passively press the drill pipe body by setting a fixed-position pressure roller, that is, it will not be pressed when the drill pipe body is not deformed, so as to prevent the drill pipe body from being deformed by heat treatment and providing heavy load pressure to damage the pipe body, and solve the contradiction that the cantilever pressure roller has a small pressure that cannot limit the heat treatment deformation of the pipe body and the high pressure damages the hot pipe body. At the same time, the limit mechanism is easy to move and adjust, and the heat treatment adjustment of pipes of different specifications is flexible and accurate, and the operability is good.

[0016] By setting the roller to connect the roller arm, the free swing of the roller is changed to a relatively fixed position. When the drill pipe body rotates on the quenching machine, the roller does not swing, which strengthens the role of limiting deformation. The angle of the roller is adjusted according to different specifications, so that the roller can independently play the role of limiting the deformation of the pipe body.

[0017] By arranging a detachable and movable correction mechanism between each rotating roller group, the function of pressing the roller where the deformation and bending are large is realized, which solves the problem that the position of the rotating roller during the internal and external spray quenching of the drill pipe body cannot be flexibly adjusted according to the bending deformation position due to the limitation of the equipment structure.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Example

[0025] like Figure 1 and Figure 2 As shown, a drill rod quenching device includes a machine tool body 100, which is a machine tool for quenching a drill rod 101. The machine tool body 100 is provided with various mechanisms such as conveying, turning and spraying. This is the prior art and will not be described in detail here. The machine tool body 100 is provided with a plurality of rotating roller groups for carrying the drill rod 101. The rotating roller groups are arranged in a straight line and are used to carry the quenched drill rod 101 and drive the drill rod 101 to rotate during quenching.

[0026] Specifically, each rotating roller group includes two rotating rollers 200, and the two rotating rollers 200 of the rotating roller group are arranged to overlap each other, so that there will be no gap between the two rotating rollers 200 in the placement direction, and the drill rod 101 can be better supported. The drill rod 101 is placed between the two rotating rollers 200. The rotating rollers 200 are driven to rotate by a motor, thereby driving the drill rod 101 to rotate, so that the drill rod 101 is rotated and sprayed, ensuring that the drill rod 101 is sprayed and cooled evenly.

[0027] A support frame 102 is provided on one side of the machine tool body 100. A plurality of correction mechanisms are hinged on one side of the support frame 102 close to the machine tool body 100, and the correction mechanisms correspond to the rotating roller groups one by one, that is, a correction mechanism is provided on the support frame 102 corresponding to each rotating roller group, so that when the drill rod 101 is placed on the rotating roller group, there is also a correction mechanism above the drill rod 101, so that the drill rod 101 is clamped in the middle by the rotating roller group and the correction mechanism, so that when the drill rod 101 rotates, if the drill rod 101 is deformed, it will be clamped and corrected by the rotating roller group and the correction mechanism;

[0028] The distance between the correction mechanism and the rotating roller group is adjustable. When clamping drill rods 101 of different sizes, the distance between the correction mechanism and the rotating roller group can be set so that the distance between the correction mechanism and the rotating roller group can just fit the drill rod 101, ensuring that the drill rod 101 will not be clamped and pressed by the rotating roller group and the correction mechanism only when it is straight and not bent or deformed. If the drill rod 101 is bent or deformed, the gap occupied by the drill rod 101 will increase when the drill rod 101 rotates, so that it will be clamped and pressed by the rotating roller group and the correction mechanism, so that the drill rod 101 is corrected and straightened.

[0029] Specifically, the correction mechanism includes a roller cylinder 201 and a roller arm 202, one end of the roller cylinder 201 is hinged to the support frame 102, one end of the roller cylinder 201 away from the support frame 102 is hinged to the roller arm 202, and one end of the roller arm 202 is hinged to the support frame 102;

[0030] The roller cylinder 201 is used to push the roller arm 202 to move, and one end of the roller arm 202 is hinged to the support frame 102, so that the roller arm 202 rotates around the hinge point between the roller arm 202 and the support frame 102 when being pushed by the roller cylinder 201, and the roller cylinder 201 is also hinged to the support frame 102, so that the roller cylinder 201 can also adaptively follow the rotation and movement of the roller arm 202;

[0031] The end of the pressure roller arm 202 away from the support frame 102 is equipped with a pressure roller 203, and the position of the pressure roller 203 on the pressure roller arm 202 is fixed, but the pressure roller 203 itself can rotate, and each pressure roller arm 202 is provided with at least two pressure rollers 203, so that the drill rod 101 can be better clamped. When the pressure roller arm 202 rotates, the pressure roller 203 is driven to move, and the length and position of the pressure roller arm 202 correspond to the setting of the rotating roller group, so that the pressure roller 203 at the end of the pressure roller arm 202 can be moved just above the rotating roller group, and with the rotation of the pressure roller arm 202, the distance between the pressure roller 203 and the rotating roller group is changed, thereby realizing the distance control between the correction mechanism and the rotating roller group. When the distance between the pressure roller 203 and the rotating roller group reaches a distance that can just accommodate the drill rod 101 without deformation, it is the target position of the rotation of the pressure roller arm 202 corresponding to the drill rod 101 of this model;

[0032] During operation, the pressure roller arm 202 is adjusted to different target positions according to the size of the drill rod 101 to be quenched. For example, when the diameter of the drill rod 101 to be quenched is small, the pressure roller 203 needs to be close to the rotating roller group to adapt to the drill rod 101, so that the distance between the pressure roller 203 and the rotating roller group matches the drill rod 101 with a smaller diameter. When the diameter of the drill rod 101 to be quenched is large, the pressure roller 203 needs to be relatively far away from the rotating roller group to adapt to the drill rod 101 with a larger diameter. The target positions of the pressure roller arm 202 in these two states are different, and the pressure roller arm 202 needs to be adjusted differently.

[0033] Specifically, the roller cylinder 201 is controlled to push the roller arm 202 to rotate, so that the distance between the roller 203 at the end of the roller arm 202 and the rotating roller group can just accommodate the position of the drill rod 101 without deformation, that is, the target position of the roller arm 202, and then the rotating roller group is rotated to start the quenching operation. In this process, since the position of the roller 203 is fixed, if the drill rod 101 is bent, the space occupied by the rotation of the drill rod 101 will become larger, and the space reserved for the rotating roller group and the roller 203 The space in which the drill rod 101 rotates is fixed, and the rotating drill rod 101 will be pressed by the rotating roller group and the pressure roller 203, so that the drill rod 101 is slowly corrected during rotation, and the pressing is passive, that is, the drill rod 101 will not be pressed when it is straight and not bent, and it will be pressed and corrected all the time when the drill rod 101 is bent, thereby achieving effective correction of the drill rod 101 and avoiding active pressure on the drill rod 101 to cause damage to the drill rod 101, or insufficient pressure to cause the drill rod 101 to be unable to be corrected.

[0034] like Figure 2As shown, further, in order to ensure the stability of the pressure roller arm 202 at the target position and to ensure sufficient pressing force on the deformed drill rod 101, a plurality of limiting mechanisms corresponding to the pressure roller arm 202 are provided between the machine tool body 100 and the support frame 102. The limiting mechanisms are used to limit the pressure roller arm 202 at the target position, so that the pressure roller arm 202 is limited at the target position, and when the pressure roller cylinder 201 applies pressure and force, the pressure roller arm 202 will not rotate and move, ensuring that the distance between the pressure roller 203 and the rotating roller group is fixed, so that the pressure roller cylinder 201 can continue to apply pressure and force when the pressure roller arm 202 reaches the target position, ensuring that the pressure roller 203 has sufficient pressing force when it abuts against the bent drill rod 101, and will not be pushed by the reaction force, resulting in a poor correction effect;

[0035] Specifically, the limiting mechanism includes a support base 300, a support rod 301 and a receiving block 302. The support base 300 is assembled on the machine tool body 100 near the rotating roller group, the support rod 301 is fixedly assembled on the support base 300, and the receiving block 302 is assembled on the end of the support rod 301 away from the support base 300.

[0036] Among them, the support base 300 is used to carry the support rod 301, the support rod 301 is used to carry the receiving block 302, and the receiving block 302 is used to receive the roller arm 202 that is limited to the target position. Because the roller arm 202 is hingedly arranged on the support frame 102, when the roller arm 202 reaches the target position, the roller arm 202 is tilted toward the rotating roller group along the hinge point of the roller arm 202 on the support frame 102, and the support rod 301 is also tilted corresponding to the tilting direction of the roller arm 202, so that the angle between the tilted support rod 301 and the roller arm 202 at the target position is closer to vertical, so that the support rod 301 can better bear the force;

[0037] like Figure 1 and Figure 2 As shown, further, in order to make the limit mechanism adapt to different target positions

[0038] The roller arm 202 supports the base 300 along the first direction ( Figure 1 The supporting base 300 is slidably assembled on the machine tool body 100 in the middle X direction, so that the movable support base 300 can drive the support rod 301 and the receiving block 302 to move, change the position of the receiving block 302, and make the receiving block 302 just contact with the pressure roller arm 202 in different target positions of the pressure roller arm 202, thereby adapting to the pressure roller arm 202 at different target positions.

[0039] Furthermore, in order to facilitate the movement and fixation of the support base 300, a displacement assembly connected to the support base 300 is provided on the machine tool body 100 for adjusting the position of the support base 300;

[0040] Specifically, the displacement assembly includes a base block 400 and a displacement screw 401. The base block 400 is fixedly mounted on the machine tool body 100, and the base block 400 is located in the first direction of the support base 300. The displacement screw 401 is threadedly penetrated through the base block 400, and one end of the displacement screw 401 is rotatably connected to the support base 300.

[0041] The base block 400 is fixedly connected to the machine tool body 100 and is used to carry the displacement screw 401. When the displacement screw 401 rotates, it moves along the first direction, and the support base 300 rotatably connected to the end of the displacement screw 401 moves with the displacement screw 401. Because of the self-locking property of the thread of the displacement screw 401, when the displacement screw 401 is rotated to bring the support base 300 to a predetermined position (i.e., at this position, the receiving block 302 just receives the roller arm 202 at the target position), the support base 300 can be locked and fixed without using other components.

[0042] During operation, the displacement screw 401 is rotated, and the rotation of the displacement screw 401 drives the support base 300 to move, thereby driving the support rod 301 and the receiving block 302 to move. When the receiving block 302 moves to the point where it can just receive the pressure roller arm 202 at the target position, the rotation of the displacement screw 401 is stopped, and the self-locking property of the displacement screw 401 makes the limit mechanism fixed and locked, thereby completing the position adjustment of the limit mechanism.

[0043] Furthermore, in order to allow the receiving block 302 to better contact the pressure roller arm 202, the receiving block 302 is rotatably arranged on the support rod 301. The receiving block 302 can rotate to different angles according to the different inclination conditions of the pressure roller arm 202, so that the upper surface of the receiving block 302 can fit with the pressure roller arm 202, thereby adapting to the different inclination angles of the pressure roller arm 202 due to different target positions.

[0044] like Figure 3 As shown, further, since the machine tool body 100 is also provided with various mechanisms such as conveying and turning materials, which will occupy a certain space, the arrangement of the rotating roller group will be restricted and cannot be arranged in a coherent and dense manner. Therefore, the drill rod 101 will be suspended for a section between two adjacent rotating roller groups, and the drill rod 101 in the suspended position is not easy to be corrected. For this reason, the support frame 102 is also provided with a detachable correction mechanism between the two adjacent rotating roller groups. The detachable correction mechanism and the support frame 102 are detachably hinged. Since the drill rod 101 on both sides of the suspended position is supported by the rotating roller group, the rotating roller group and the detachable correction mechanism of the drill rod 101 in the suspended position form an offset clamping. Therefore, the detachable correction mechanism can also press and correct the drill rod 101 in the suspended position. At the same time, the detachable correction mechanism can be disassembled and assembled to different suspended positions according to different drill rod 101 models to better adapt to different processing conditions.

[0045] During operation, according to the size of the drill rod 101 that needs to be quenched, the displacement screw 401 is rotated to drive the support base 300 to move. When the support base 300 moves to a predetermined position where the receiving block 302 can just receive the pressure roller arm 202 at the target position, the displacement screw 401 is stopped, and then the drill rod 101 that needs to be quenched is placed on the rotating roller group, and the pressure roller cylinder 201 is started. The pressure roller cylinder 201 pushes the pressure roller arm 202 to the target position, so that the distance between the pressure roller 203 and the rotating roller group can just accommodate the drill rod 101. At this time, the receiving block 302 also just receives the pressure roller arm 202 to prevent the pressure roller arm 202 from continuing to press down, so that the pressure roller 203 damages the drill rod 101. Then the rotating roller group is rotated and the spray mechanism is determined, and the drill rod 101 can be quenched and corrected.

[0046] Through the solution of the present application, the straightness of the drill pipe 101 is significantly improved after heat treatment, especially the straightness of the thick-walled pipe is significantly improved. The statistical results are shown in Table 1.
