Description

Technical Field

[0001] This invention relates to the technical field of weld treatment, and in particular to a double-gate tempering ring for automated weld treatment. Background Technology

[0002] In the oil drilling and production field, friction-welded drill pipes are widely used due to their efficient and reliable connection performance. After welding, the weld and heat-affected zone will form a hard and brittle martensitic structure, which must be reduced in hardness and improved in toughness through tempering to meet the stringent requirements of downhole working conditions. Therefore, the tempering process is a key process that determines the service life and safety of the drill pipe. Currently, the industry commonly uses a single-gate integral tempering furnace for heat treatment of welded rods. This method has significant inherent drawbacks: excessive energy consumption, the need for uniform heating of the entire long area, with a large amount of energy being consumed in parts of the rod that do not require high-temperature treatment, large furnace heat dissipation area leading to low thermal efficiency, and the reliance on manual experience for weld alignment, making temperature uniformity control difficult and ensuring consistent product quality. In summary, there is a need to invent a double-gated tempering ring for automated weld processing. This equipment can clamp drill rods of different sizes, reducing the cost of purchasing different sizes. Furthermore, this equipment improves upon the traditional single-gated tempering ring by adding a double-gated tempering ring, resulting in significant improvements in power consumption and weld performance compared to the single-gated tempering method, achieving both cost reduction and quality enhancement. This equipment can also adjust the double-gated tempering ring to better handle weld widths, improving efficiency. Additionally, it can adjust the position of the drill rod, facilitating the concentration of the weld near the tempering ring. Summary of the Invention

The drill rod 4 is inserted into the clamping part 1, the adjusting tempering ring part 2, and the transmission part 3. Specifically, the drill rod 4 is inserted into the clamping part 1 and the transmission part 3, and then the clamping part 1 and the transmission part 3 are used to adjust the drill rod 4 so that the weld of the drill rod 4 is moved below the adjusting tempering ring part 2, which facilitates the treatment of the weld. The clamping part 1 includes: a first cylindrical gear 101, a large gear 102, a sleeve 103, a motor 104, and a limiting frame 105; The first cylindrical gear 101 is fixedly connected to the shaft of the motor fixedly mounted on the sleeve 103. The first cylindrical gear 101 meshes with the large gear 102. The large gear 102 is rotatably mounted on the sleeve 103. The sleeve 103 is slidably mounted in the grooves of two limit frames 105. There are two limit frames 105, which are fixedly mounted on the ground respectively. The motor 104 is fixedly mounted on the circular collar 106. Specifically, the motor on the sleeve 103 drives the first cylindrical gear 101 to rotate, which in turn drives the large gear 102 to rotate, thereby driving the cylindrical sleeve 109 to rotate.

[0028] In one optional embodiment of the present invention, such as Figure 3 , Figure 4 As shown, the clamping part 1 also includes: a circular collar 106, a lead screw moving mechanism 107, a limiting support plate 108, a cylindrical sleeve 109, and a fixing structure; A circular collar 106 is fixedly connected to a cylindrical sleeve 109. Two lead screw moving mechanisms 107 are fixedly installed on the circular collar 106. The lead screws of the two lead screw moving mechanisms 107 are connected to the shaft of the motor 104 via belts and pulleys. The sliders of the two lead screw moving mechanisms 107 are fixedly connected to the limiting support plate 108. The limiting support plate 108 is slidably installed on the cylindrical sleeve 109, and the cylindrical sleeve 109 is fixedly connected to the sleeve 103. There are four sets of fixing structures, which are respectively installed on the limiting support plate 108 and the cylindrical sleeve 109. Specifically, the motor 104 drives the belt and pulley to rotate, which in turn drives the lead screws of the two lead screw moving mechanisms 107 to rotate, which in turn drives the limiting support plate 108 to move, which further drives the rack 110 to move, which in turn drives the pinion 111 to rotate, which in turn drives the swing rod 112 to rotate, so that the pressing plate 113 presses against the drill rod 4, thereby providing support force to the drill rod 4.

[0029] In one optional embodiment of the present invention, such as Figure 3 , Figure 4As shown, the fixing structure includes: a rack 110, a pinion 111, a swing rod 112, and a pressing plate 113; The rack 110 is fixedly connected to the limiting support plate 108. The rack 110 meshes with the pinion 111. The pinion 111 is fixedly connected to the swing rod 112. The swing rod 112 is rotatably mounted on the cylindrical sleeve 109. One end of the swing rod 112 is fixedly connected to the extrusion plate 113.

[0030] In one optional embodiment of the present invention, such as Figure 5 , Figure 6 As shown, the adjusting tempering ring part 2 includes: a rectangular support plate 201, a connecting support plate 202, a cam 203, and an L-shaped support rod 206; There are two rectangular support plates 201, which are fixedly installed on the ground. The connecting support plate 202 is fixedly connected to the shaft of the motor fixedly installed on the cam 203, and the cam 203 is fixedly connected to the two rectangular support plates 201. There are four L-shaped support rods 206, two of which are slidably installed on the trapezoidal block 205, and four L-shaped support rods 206 are fixedly connected to four rectangular locking blocks 214. Specifically, the motor on the cam 203 drives the connecting support plate 202 to rotate, thereby causing the connecting support plate 202 to push the two trapezoidal blocks 205 to move in opposite directions. This causes the two trapezoidal blocks 205 to drive the four cylindrical support rods 204 to move in opposite directions, thereby driving the four rectangular locking blocks 214 to move in opposite directions. This causes the four rectangular locking blocks 214 to drive the two single flash rings 215 to move in opposite directions, thereby adjusting the distance between the two single flash rings 215.

[0031] In one optional embodiment of the present invention, such as Figure 5 , Figure 6 As shown, the tempering ring adjustment part 2 also includes: a cylindrical support rod 204 and a trapezoidal block 205; There are four cylindrical support rods 204. Every two cylindrical support rods 204 are fixedly installed on two trapezoidal blocks 205, and every two cylindrical support rods 204 are slidably installed on two rectangular support plates 201.

[0032] In one optional embodiment of the present invention, such as Figure 4 , Figure 5 As shown, the tempering ring adjustment part 2 also includes: a groove plate 207, a support plate 208, a second cylindrical gear 209, a swing support plate 210, and a limiting support rod 211; There are two grooved plates 207, which are slidably mounted on two limiting rods 211 respectively; there are two limiting rods 211, which are fixedly mounted on the ground respectively; there are two support plates 208, which are fixedly mounted on the ground respectively, and a motor is fixedly mounted on one of the support plates 208, with the motor shaft fixedly connected to one of the second cylindrical gears 209; there are two second cylindrical gears 209, which are rotatably mounted on the two support plates 208 respectively, and the two second cylindrical gears 209 mesh with each other; there are two swing support plates 210, each of which is provided with a sliding groove, and a grooved plate 207 is slidably mounted in each groove. 7. The side rod has two swing support plates 210 rotatably mounted on two support plates 208. Each swing support plate 210 is connected to a second cylindrical gear 209 via a belt and a pulley. Specifically, the motor on one of the support plates 208 drives one of the second cylindrical gears 209 to rotate, which in turn drives the other second cylindrical gear 209 to rotate, which in turn drives the two swing support plates 210 to rotate, further driving the two slotted plates 207 to move, thereby pushing the cylindrical support rod 204 to retract into the trapezoidal block 205, which in turn drives the rectangular block 213 and four rectangular locking blocks 214 to move, so that the four rectangular locking blocks 214 lock the two single tempering rings 215, which facilitates the adjustment of the single tempering rings 215.

[0033] In one optional embodiment of the present invention, such as Figure 5 , Figure 6 As shown, the tempering ring adjustment part 2 also includes: a rectangular bracket 212, a rectangular block 213, a rectangular locking block 214, and a single tempering ring 215; There are four rectangular brackets 212, which are fixedly installed on the ground. Each rectangular bracket 212 has a spring fixedly installed inside, and one end of each spring is fixedly connected to a rectangular block 213. There are four rectangular blocks 213, which are slidably installed in the four rectangular brackets 212. Each rectangular block 213 is slidably connected to a rod on the side of a rectangular locking block 214. There are four rectangular locking blocks 214, and their rear ends are slidably installed in the grooves of the channel plate 207. Each of the four rectangular locking blocks 214 has a spring fixedly installed on its side, which can increase the pushing force. The other end of the spring is fixedly connected to a rectangular block 213. Two single tempering rings 215 are connected to the external structure.

[0034] In one optional embodiment of the present invention, such as Figure 7 , Figure 8 As shown, the transmission section 3 includes: a rectangular frame 301 and a spray box 306; There are two rectangular frames 301, which are fixedly installed on the ground respectively; the spray box 306 is fixedly installed on the two rectangular frames 301.

[0035] In one optional embodiment of the present invention, such as Figure 7 , Figure 8 As shown, the transmission section 3 also includes: a circular plate 302, a rectangular support rod 303, a support frame 304, and an electric extrusion wheel 305; There are two circular plates 302, each with a rectangular support rod 303 slidably mounted on it. Each rectangular support rod 303 has a spring wrapped around its outer side. One end of the spring is fixedly connected to a support frame 304, and the other end is fixedly connected to the circular plate 302. There are two support frames 304, each with an electric extrusion wheel 305 mounted on it. A PLC module is mounted on each electric extrusion wheel 305. Specifically, a drill rod 4 is inserted between the two electric extrusion wheels 305. Then, due to the springs wrapped around the rectangular support rods 303, the electric extrusion wheels 305 and the support frames 302... The drill rod 4 descends, and a spring applies pressure to it. Two electric extrusion rollers 305 then move the drill rod 4, facilitating the placement of the weld seam. Simultaneously, the two electric extrusion rollers 305 check straightness. Using the PLC modules on the electric extrusion rollers 305, coaxiality values ​​can be input according to actual needs, and related tests can be completed. The equipment will automatically judge based on the relevant values, and for those that do not meet the requirements, it will automatically apply paint markings in conjunction with the spray painting box 306, making the results clearly visible on the material and preventing the misuse of defective products. This is a cost-reduction project.

[0036] Working principle: This equipment can clamp drill rods of different sizes, reducing the cost of procuring different sizes. Furthermore, it improves upon the traditional single-gate tempering ring by adding a double-gate tempering ring, significantly improving power consumption and weld performance compared to the single-gate tempering method, achieving both cost reduction and quality improvement. Additionally, it utilizes PLC modules to input coaxiality values ​​based on actual needs and complete related tests. The equipment automatically judges based on these values ​​and, in conjunction with the 306 spray painting box, automatically paints and marks any non-compliant parts, making the results clearly visible on the materials and preventing the misuse of defective products, thus contributing to cost reduction. Moreover, the equipment can adjust the double-gate tempering ring to better handle weld widths, improving efficiency. The drill rod 4 is inserted between two electric extrusion rollers 305. Then, due to the spring wrapped around the outside of the rectangular support rod 303, the electric extrusion rollers 305 and the support frame 304 are lowered, and the springs generate extrusion force on the drill rod 4. Subsequently, the two electric extrusion rollers 305 drive the drill rod 4 to move, so as to move the weld of the drill rod 4 to the appropriate position. At the same time, the straightness is detected by moving the drill rod 4 using the two electric extrusion rollers 305. Using the relevant PLC module on the electric extrusion roller 305, the coaxiality value can be input according to actual needs and the relevant tests can be completed. The equipment will make its own judgment based on the relevant values, and automatically spray paint markings for those that do not meet the requirements in conjunction with the spraying box 306. After the drill rod 4 is inserted into the cylindrical sleeve 109, the motor 104 drives the belt and pulley to rotate, which in turn drives the lead screws of the two lead screw moving mechanisms 107 to rotate, which in turn drives the limit support plate 108 to move, which further drives the rack 110 to move, which in turn drives the pinion 111 to rotate, which in turn drives the swing rod 112 to rotate, so that the pressing plate 113 presses the drill rod 4, thereby providing support force to the drill rod 4; In order to ensure uniform heat during the welding process of the double-gate tempering ring, the motor on the sleeve 103 drives the first cylindrical gear 101 to rotate, which in turn drives the large gear 102 to rotate, thereby driving the cylindrical sleeve 109 to rotate, and in turn driving the drill rod 4 to rotate. The motor on one of the support plates 208 drives one of the second cylindrical gears 209 to rotate, which in turn drives the other second cylindrical gear 209 to rotate, which in turn drives the two swing support plates 210 to rotate, which further drives the two slotted plates 207 to move, thereby pushing the cylindrical support rod 204 to retract into the trapezoidal block 205, which in turn drives the rectangular block 213 and four rectangular locking blocks 214 to move, so that the four rectangular locking blocks 214 lock the two single tempering rings 215, making it easy to adjust the single tempering rings 215; The motor on the cam 203 drives the connecting support plate 202 to rotate, which in turn pushes the two trapezoidal blocks 205 to move in opposite directions. This causes the two trapezoidal blocks 205 to move the four cylindrical support rods 204 in opposite directions, which in turn causes the four rectangular clamping blocks 214 to move in opposite directions. This, in turn, causes the four rectangular clamping blocks 214 to move the two single tempering rings 215 in opposite directions, thereby adjusting the distance between the two single tempering rings 215. This allows for centralized processing based on the width of the weld, improving processing efficiency.
