Description

Technical Field

[0001] The invention relates to the technical field of drill bits, in particular to a cobalt removal combined tooling for cutting teeth of a diamond composite drill bit. Background Art

[0002] Diamond composite sheets are used in PDC drill bit cutting teeth and cutting tools. After decobalting, diamond composite sheets have significantly improved heat resistance, wear resistance, and impact resistance. With the improved performance of diamond composite sheets, the service life of PDC drill bits and cutting tools will be greatly increased, bringing higher economic benefits. As the decobalt layer of the diamond composite sheet deepens, the life of the composite sheet will be correspondingly extended, but decobalting will take longer and be more expensive. Furthermore, as the synthesis pressure increases, the density of the diamond composite sheet increases, and the reaction conditions for decobalting become increasingly stringent. High temperature, high pressure, strong acid, and even strong stirring, gas stirring, or strong ultrasonic assistance are often required to achieve good results.

[0003] The existing combined tooling, due to its simple structure, can only clamp diamonds of a specific size. At the same time, during the diamond processing process (such as the decobalting process), the traditional tooling causes the diamond position to shift due to unstable clamping, affecting the processing effect.

[0041] Furthermore, the sealing structure 7 includes a sealing plate 71 rotatably connected to the rear end of the upper end face of the storage rack 21 through a bracket, the inner cavity side wall of the sealing plate 71 is rotatably connected to a transmission crank arm 72, the end of the transmission crank arm 72 away from the sealing plate 71 is rotatably connected to a transmission plate 73, the front end face of the transmission plate 73 is fixedly connected to a cover plate 74, the front end face of the cover plate 74 is evenly fixedly connected to a clamping structure 10, and the middle part of the rear end face of the sealing plate 71 is fixedly connected to a lifting structure 8.

[0042] Furthermore, the lifting structure 8 includes a lifting frame 81 fixedly connected to the middle part of the rear end surface of the sealing plate 71, the inner cavity of the lifting frame 81 is rotatably connected to the winding roller 82, and the outer surface of the winding roller 82 is symmetrically wound with a transmission cable 83, and the end of the transmission cable 83 away from the winding roller 82 is fixedly connected to the cover plate 74.

Through the lifting structure 8 on the sealing structure 7, the lifting and lowering of the cover plate 74 are adjusted by the lifting frame 81 and the winding roller 82 during use, and then the relative height of the cover plate 74 is adjusted by the winding of the transmission cable 83.

[0043] Furthermore, the driving structure 9 includes a driving worm gear 91 rotatably connected to the middle part of the upper end face of the lifting frame 81. The rear end face of the sealing plate 71 is located above the driving worm gear 91 and is rotatably connected to the driving worm 92 through the connecting frame. The driving worm gear 91 and the driving worm 92 are meshed with each other. The rear end face of the sealing plate 71 is located on the right side of the driving worm 92 and is fixedly connected to a driving motor 93. The right end face rotating shaft of the driving worm 92 is fixedly connected to the output end of the driving motor 93. The upper end face rotating shaft of the winding roller 82 is fixedly connected to the driving worm gear 91. The driving structure 9 on the lifting structure 8 provides power for the movement of the cover plate 74, so that the cover plate 74 can be accurately immersed in the composite acid, ensuring that the ultrasonic vibration wave and the composite acid act together on the diamond normally during the decobalting process.

[0044] Furthermore, the clamping structure 10 includes a clamping block 101 uniformly fixedly connected to the front end face of the cover plate 74, a connecting groove 102 is opened in the middle of the front end face of the clamping block 101, the front end face of the clamping block 101 is uniformly rotated and connected to the clamping claw 103 through the rotating frame with the connecting groove 102 as the center, and the rear end face of the inner cavity of the connecting groove 102 is fixedly connected to the adjusting structure 11. Through the clamping structure 10 on the sealing structure 7, diamonds of different sizes and sizes can be stably clamped to ensure that the position of the diamond is fixed during the decobalting process, which is conducive to the uniform action of ultrasonic vibration waves and composite acid on the diamond, thereby improving the effect and quality of decobalting.

[0045] Furthermore, the adjustment structure 11 includes an adjustment spring 111 fixedly connected to the rear end face of the connecting groove 102, and the front end face of the adjustment spring 111 is fixedly connected to the adjustment block 112, and the transmission rod 113 is rotatably connected between the side of the clamping jaw 103 close to the connecting groove 102 and the adjustment block 112 through a bracket, and the inner cavity of the adjustment spring 111 is movably sleeved with a telescopic rod, and the front and rear ends of the telescopic rod are respectively fixedly connected to the adjustment block 112 and the connecting groove 102. Through the adjustment structure 11 on the clamping structure 10, the distance between the clamping jaws 103 is adjusted by moving the adjustment block 112 and the transmission rod 113 during use, and then the diamond composite sheets of different sizes are firmly clamped by tightening the adjustment spring 111.

[0046] Working principle: When working, the sealing structure 7 is pulled, so that the sealing plate 71 rotates backward with the rotating frame connected to the storage rack 21 as the center of the circle, thereby opening the sealing plate 71.

[0047] Pull the jaws 103 toward each other, so that the two jaws 103 rotate toward each other. At this time, the transmission rod 113 rotates, and then the height of the adjustment block 112 rises through the transmission effect of the transmission rod 113, so the adjustment spring 111 extends. At this time, the person places the diamond between the jaws 103 and on the front end of the adjustment block 112. At this time, the person releases the jaws 103, so the adjustment spring 111 contracts, so that the adjustment block 112 slides backward. At this time, the jaws 103 are driven by the transmission rod 113 and move closer to each other. Therefore, the jaws 103 can stably clamp diamonds of different sizes.

[0048] When decobalting is required, the external pipe is threadedly connected to the connecting pipe 43 to transport the composite acid such as sulfuric acid and hypochlorous acid to the inner cavity of the conveying rack 41. Due to the liquid pressure, the flow block 533 slides to the left, so the spring 532 and the telescopic inner rod 531 contract, so that the composite acid liquid enters the inner cavity of the storage rack 21 through the conveying rack 41 and the liquid exchange port 22. At this time, the sealing plate 71 is pushed to rotate in the opposite direction, so that the sealing plate 71 and the storage rack 21 fit together, so that the cover plate 74 and the clamping structure 10 are located in the inner cavity of the storage rack 21. At this time, the driving structure 9 is started to rotate the output end of the driving motor 93, so the driving worm 92 rotates. Since the driving worm 92 and the driving worm wheel 91 are mutually engaged, the sealing plate 71 and the clamping structure 10 are located in the inner cavity of the storage rack 21. The worm gear 91 is meshed, so the worm gear 91 is driven to rotate. Furthermore, since the worm gear 91 is fixedly connected to the winding roller 82, the winding roller 82 rotates, causing the transmission cable 83 to unwind. At this time, the cover plate 74 moves downward due to gravity, and rotates through the transmission crank arm 72, so that the cover plate 74 is immersed in the composite acid such as sulfuric acid and hypochlorous acid. At this time, the ultrasonic vibration structure 3 is started, so that the ultrasonic vibration motor 33 starts to work, so that the vibration-type ultrasonic wave is transmitted to the composite acid through the vibration rod 31. Since the composite acid is a liquid, the ultrasonic vibration wave is transmitted to the diamond due to the liquid conductive property. At this time, the cobalt removal of the diamond composite sheet is achieved through the combined action of the ultrasonic vibration wave and the composite acid.

[0049] When the decobaltization is completed, the handle on the rotating shaft 51 is turned to rotate the rotating shaft 51, and then the telescopic structure 53 is rotated 180 degrees with the rotating shaft 51 as the center through the mounting frame 52, so that the flow blocking block 533 and the left limit ring 42 are engaged with each other. At this time, the personnel starts the external pump body to suck the gas in the inner cavity of the conveying frame 41. Due to the reduction of gas, the inner cavity of the connecting pipe 43 generates negative pressure. At this time, the telescopic structure 53 is caused by the negative pressure to make the flow blocking block 533 slide to the right, so the spring 532 and the telescopic inner rod 531 contract, thereby discharging the waste liquid generated after the reaction through the conveying frame 41.

[0050] At the same time, when the liquid flows back, the liquid pressure or the negative pressure in the pipeline decreases, so the spring 532 extends, so the telescopic inner rod 531 extends, so that the flow block 533 and the limiting ring 42 on the corresponding side engage with each other, thereby blocking the inner cavity of the conveying frame 41, thereby realizing one-way flow of the liquid.

[0051] When the mounting bracket 52 rotates, the gear 61 is fixedly connected to the mounting bracket 52, so the gear 61 rotates. At this time, the limiting column 623 engaged with the gear 61 shrinks toward the inner cavity of the limiting bracket 621, so the limiting spring 622 shrinks. When the rotation of the mounting bracket 52 is completed, the gear 61 stops rotating, so the limiting spring 622 extends, and then the limiting column 623 slides to the left, so that the limiting column 623 and the gear 61 are engaged with each other, thereby achieving the limiting fixation of the rotating mounting bracket 52.
