Description

Technical Field

[0001] The present invention relates to the technical field of strong acid cobalt removal for diamond composite sheets, and specifically relates to a production device and a production method for strong acid cobalt removal of diamond composite sheets. Background Art

[0002] Currently, the main method for cobalt removal of diamond composite sheets is to place the diamond composite sheets into a mold, inject cobalt removal liquid into the mold, and then subject the mold to high temperature to accelerate the cobalt removal reaction. However, in some existing technologies, the diamond composite sheets are fixed above a solution tank by a fixture, and the composite layer of the diamond composite sheets is immersed in the cobalt removal liquid in the solution tank, and the cobalt removal process is completed in a static state. During this process, there may be a gap between the diamond composite sheets and the fixture, which may allow strong acid to enter and corrode the cemented carbide (the part of the diamond composite sheet fixed by the fixture is the basic part of the cemented carbide, and the composite layer to be cobalt-removed will be exposed outside the fixture). Although some use sealing rings installed in the gap to block the entry of strong acid, when the sealing ring is made of alloy, it will cause hard friction between the sealing ring and the diamond composite sheet when installing the sealing ring, damaging the diamond composite sheet. Moreover, the sealing ring needs to be installed after clamping the diamond composite sheet and removed before unloading the diamond composite sheet. The repeated disassembly and installation of the sealing ring will make the clamping process and disassembly process of the diamond composite sheet cumbersome. If a rubber-made sealing ring is used, although the diamond composite sheet can be forcibly disassembled without prior removal of the sealing ring, and the diamond composite sheet can also be directly inserted into the fixture with the sealing ring already installed, without repeated disassembly and installation of the sealing ring for clamping and unloading the diamond composite sheet, but it will not provide a protective effect due to being easily corroded and damaged by strong acid. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, meet the actual needs, and provide a production device and a production method for strong acid cobalt removal of diamond composite sheets that can block the gap to prevent strong acid from entering and is also convenient for clamping and disassembly, so as to solve the above technical problems.

[0005] (2) Technical Solutions

[0006] In order to achieve the purpose of the present invention, the technical solutions adopted by the present invention are as follows:

[0007] A production device for strong acid decobalt of diamond composite sheets, including a working box body. A heater is fixedly arranged at the bottom of the working box body. A feed inlet is arranged on the side of the working box body, and an electric control door is arranged on the feed inlet. A first hydraulic cylinder is fixedly arranged at the inner bottom of the working box body, and a blanking plate capable of reciprocatingly moving in the working box body is fixedly arranged on the piston rod of the first hydraulic cylinder. A plurality of object clamping components are uniformly distributed along the length direction of the bottom of the blanking plate. A first blocking component is arranged on one side part of the blanking plate, and a second blocking component is arranged on the other side part of the blanking plate.

[0008] The first blocking component includes two second hydraulic cylinders fixedly arranged on one side part of the blanking plate. A first blocking block capable of reciprocatingly moving is arranged on the piston rods of the two second hydraulic cylinders. The second blocking component includes two third hydraulic cylinders fixedly arranged on the other side part of the blanking plate. A second blocking block capable of reciprocatingly moving is fixedly arranged on the piston rods of the two third hydraulic cylinders. A first semi-circular groove is arranged on the side of the first blocking block close to the object clamping component, and a second semi-circular groove is arranged on the side of the second blocking block close to the object clamping component. When the first blocking block and the second blocking block are in contact, the inner walls of the first semi-circular groove and the second semi-circular groove are in contact to form a complete circular groove.

[0009] A transmission cavity is arranged in the first blocking block. A movable block capable of reciprocatingly moving is arranged in the transmission cavity. The second hydraulic cylinder is fixedly connected with the movable block. A tension spring is fixedly arranged between the movable block and the inner wall of the side of the transmission cavity close to the second hydraulic cylinder. The object clamping component includes a mounting shaft rotatably connected to the bottom of the blanking plate. A positioning tube is fixedly arranged at the end of the mounting shaft far from the blanking plate. A magnet is fixedly arranged at the bottom of the positioning tube. A rotating gear is fixedly arranged on the mounting shaft. A first torsion spring is sleeved on the mounting shaft. One end of the first torsion spring is fixedly arranged on the mounting shaft, and the other end is fixedly arranged on the blanking plate.

[0010] The object clamping component further includes a matching block fixedly arranged on the movable block. The matching block can reciprocatingly penetrate out of the transmission cavity. A plurality of tooth components are uniformly distributed along the length direction of the matching block.

[0011] The tooth component includes a mounting plate fixedly arranged on the side surface of the matching block. A rotating shaft is rotatably arranged on the mounting plate. A meshing tooth is fixedly arranged on the rotating shaft. A second torsion spring is sleeved on the rotating shaft. One end of the second torsion spring is fixedly arranged on the rotating shaft, and the other end is fixedly arranged on the mounting plate. A resisting rod is fixedly arranged on the matching block. When the matching block moves in a direction away from the second hydraulic cylinder, the resisting rod will resist the meshing tooth to prevent the meshing tooth from rotating.

[0012] The inner wall of the first semi-circular groove is provided with a first semi-circular annular groove, the inner wall of the second semi-circular groove is provided with a second semi-circular annular groove, a first clamping block capable of reciprocating in the first semi-circular annular groove is arranged in the first semi-circular annular groove, and a second clamping block capable of reciprocating in the second semi-circular annular groove is arranged in the second semi-circular annular groove.

[0013] On both sides of the outer surface of the positioning tube, a first positioning block and a second positioning block are respectively and fixedly arranged. On one side surface of the first clamping block close to the positioning tube, a first clamping groove matched with the first positioning block is arranged, and on one side surface of the second clamping block close to the positioning tube, a second clamping groove matched with the second positioning block is arranged.

[0014] Lubricating oil is coated in the first semi-circular annular groove and the second semi-circular annular groove.

[0015] The inner diameter of the positioning tube is set to be 1-2 mm larger than the maximum outer diameter of the diamond composite sheet to be processed.

[0016] A production method for strong acid cobalt removal of diamond composite sheets, using the above-mentioned production device for strong acid cobalt removal of diamond composite sheets, includes the following steps:

[0017] S1. First, put strong acid into the working box body, and put diamond composite sheets into each clamping component.

[0018] S2. Start the heater to heat the strong acid to 90 °C, and then start the first hydraulic cylinder to immerse the diamond composite sheets into the strong acid for cobalt removal.

[0019] S3. Protect the diamond composite sheets through the first gear component and the second gear component.

[0020] Beneficial effects: A. By making the second stop block and the first stop block closely adhere to the diamond composite sheet in advance, it can be avoided that when the diamond composite sheet enters the strong acid solution, the liquid level will splash out the strong acid solution through the gap between the positioning tube and the composite sheet and contact the cemented carbide layer, causing damage to the cemented carbide. It can also be avoided that the strong acid solution carried out when the diamond composite sheet leaves the liquid level enters the gap between the positioning tube and the diamond composite sheet to corrode the cemented carbide. Moreover, since the diamond composite sheet can be attracted by a magnet, a 1-2 mm gap can be left between the diamond composite sheet and the inside of the positioning tube, which is convenient for putting in and taking out the diamond composite sheet.

[0021] After the decobaltization is completed, the first hydraulic cylinder is started to drive the diamond composite sheet away from the liquid surface. Then, the two second hydraulic cylinders are started continuously to push the meshing teeth to move away from the two second hydraulic cylinders against the resistance of the tension spring until the meshing teeth are separated from the rotating gear. At this time, the rotating gear will rotate and reset under the action of the first torsion spring. At the same time of resetting, the rotating gear will drive the diamond composite sheet to rotate together, so that the redundant strong acid liquid remaining on the diamond composite sheet can be thrown out as much as possible by centrifugal force, avoiding the loss caused by the remaining strong acid liquid dropping onto the external equipment or the operator when the diamond composite sheet is taken out.

[0022] C. Through the setting that the second stopper and the first stopper first adhere to the diamond composite sheet, and then the two second hydraulic cylinders are started continuously to push the meshing teeth to move away from the two second hydraulic cylinders against the resistance of the tension spring until the meshing teeth are separated from the rotating gear. At this time, the rotating gear will rotate and reset under the action of the first torsion spring, which can ensure that when the strong acid is thrown out by centrifugal force, the second stopper and the first stopper are in a state of closely adhering to the diamond composite sheet, so as to ensure that the thrown strong acid liquid will not be thrown into the gap between the positioning tube and the composite sheet to corrode the cemented carbide.

[0032] The following combines the attached Figures 1 - 9 and embodiments to further illustrate the present invention:

[0033] A production device for strong acid decobalt of diamond composite sheets includes a working box body 1. A heater 2 is fixedly arranged at the bottom of the working box body 1. A feed inlet 3 is arranged on the side of the working box body 1. An electric control door 4 is arranged on the feed inlet 3. A first hydraulic cylinder 5 is fixedly arranged at the bottom inside the working box body 1. A blanking plate 6 that can reciprocate inside the working box body 1 is fixedly arranged on the piston rod of the first hydraulic cylinder 5. A plurality of object clamping components 7 are evenly distributed along the length direction of the bottom of the blanking plate 6. A first blocking component 8 is arranged on one side of the blanking plate 6, and a second blocking component 9 is arranged on the other side of the blanking plate 6.

[0034] The first blocking component 8 includes two second hydraulic cylinders 80 fixedly arranged on one side of the blanking plate 6. A first blocking block 81 that can reciprocate is arranged on the piston rods of the two second hydraulic cylinders 80. The second blocking component 9 includes two third hydraulic cylinders 91 fixedly arranged on the other side of the blanking plate 6. A second blocking block 92 that can reciprocate is fixedly arranged on the piston rods of the two third hydraulic cylinders 91. A first semi-circular groove 93 is arranged on the side of the first blocking block 81 close to the object clamping component, and a second semi-circular groove 94 is arranged on the side of the second blocking block 92 close to the object clamping component. When the first blocking block 81 and the second blocking block 92 are in contact, the inner walls of the first semi-circular groove 93 and the second semi-circular groove 94 are in contact to form a complete circular groove.

[0035] A transmission cavity 500 is arranged inside the first blocking block 81. A movable block 501 that can reciprocate is arranged inside the transmission cavity 500. The second hydraulic cylinder 80 is fixedly connected to the movable block 501. A tension spring is fixedly arranged between the movable block 501 and the inner wall of the transmission cavity 500 close to the second hydraulic cylinder 80. The object clamping component 7 includes a mounting shaft 71 rotatably connected to the bottom of the blanking plate 6. A positioning tube 72 is fixedly arranged at the end of the mounting shaft 71 away from the blanking plate 6. A magnet 73 is fixedly arranged at the bottom of the positioning tube 72. A rotating gear 74 is fixedly arranged on the mounting shaft 71. The mounting shaft 71 is sleeved with a first torsion spring. One end of the first torsion spring is fixedly arranged on the mounting shaft 71, and the other end is fixedly arranged on the blanking plate 6.

[0036] The object clamping component 7 further includes a matching block 75 fixedly arranged on the movable block 501. The matching block 75 can reciprocate through the transmission cavity 500. A plurality of tooth components are evenly distributed along the length direction of the matching block 75.

[0037] The tooth assembly includes a mounting plate 76 fixedly arranged on the side surface of the mating block 75. A rotating shaft 77 is rotatably arranged on the mounting plate 76. A meshing tooth 377 is fixedly arranged on the rotating shaft 77. A second torsion spring is sleeved on the rotating shaft 77. One end of the second torsion spring is fixedly arranged on the rotating shaft 77, and the other end is fixedly arranged on the mounting plate 76. The mating block 75 is fixedly provided with a resisting rod 801. When the mating block 75 moves away from the second hydraulic cylinder 80, the resisting rod 801 will resist the meshing tooth 377 to prevent the meshing tooth 377 from rotating. By arranging the tooth assembly, only before the cobalt removal by immersing in acid, when the first stop block and the second stop block approach the diamond composite sheet, the meshing tooth drives the rotating gear to rotate. And after the cobalt removal is completed, when it is necessary to remove the diamond composite sheet, when the meshing tooth 377 moves towards the second hydraulic cylinder, when encountering the rotating gear, the meshing tooth will fall down by itself under the obstruction of the rotating gear and cannot drive the rotating gear to rotate, so as to avoid the first stop block and the second stop block driving the diamond composite sheet to rotate when separating from the diamond composite sheet, resulting in a small part of the residual liquid droplets that may not have been completely thrown out by centrifugal force before being thrown into the gap between the adjacent diamond composite sheet and the positioning tube to corrode the cemented carbide.

[0038] The inner wall of the first semi-circular groove 93 is provided with a first semi-circular annular groove 600, and the inner wall of the second semi-circular groove 94 is provided with a second semi-circular annular groove 601. A first clamping block 602 that can reciprocate in the first semi-circular annular groove 600 is arranged in the first semi-circular annular groove 600, and a second clamping block 603 that can reciprocate in the second semi-circular annular groove 601 is arranged in the second semi-circular annular groove 601.

[0039] On both sides of the outer surface of the positioning tube 72, a first positioning block 604 and a second positioning block 605 are respectively fixedly arranged. On the side surface of the first clamping block 602 close to the positioning tube 72, a first clamping groove 608 that cooperates with the first positioning block 604 is arranged. On the side surface of the second clamping block 603 close to the positioning tube 72, a second clamping groove 609 that cooperates with the second positioning block 605 is arranged; through the arrangement of the first positioning block, the second positioning block, the first clamping groove, and the second clamping groove, when the first clamping block and the second clamping block are in close contact with the diamond composite sheet, the first positioning block will enter the first clamping groove, and the second positioning block will enter the second clamping groove. Thus, when the positioning tube drives the diamond composite sheet to rotate, it will also drive the first clamping block 602 and the second clamping block 603 to rotate synchronously, so as to avoid large friction between the diamond composite sheet and the first clamping block and the second clamping block when the diamond composite sheet rotates, causing damage to the diamond composite sheet. The inner diameter of the positioning tube is set to be 1 - 2 mm larger than the maximum outer diameter of the diamond composite sheet to be processed, so as to facilitate clamping and disassembly.

[0040] Lubricating oil is coated in the first semi-circular annular groove 600 and the second semi-circular annular groove 601.

[0041] A production method for strong acid cobalt removal of diamond composite sheets, using the above-mentioned production device for strong acid cobalt removal of diamond composite sheets, includes the following steps:

[0042] S1. First, put strong acid into the working box body 1, and put diamond composite sheets into each clamping component 7;

[0043] S2. Start the heater 2 to heat the strong acid to 90 °C, and then start the first hydraulic cylinder 5 to immerse the diamond composite sheets into the strong acid for cobalt removal;

[0044] S3. Protect the diamond composite sheets through the first gear component and the second gear component.

[0045] The working principle of the present invention includes the following process:

[0046] Open the electric control door 4, put the diamond composite sheet into the positioning tube 72, and suck the diamond composite sheet by the magnet 73 to prevent the diamond composite sheet from falling out of the positioning tube 72. At the same time, start the heater 2 to heat the strong acid solution, and then start the first gear component 8 and the second gear component 99 to drive the second block 92 and the first block 81 to approach the diamond composite sheet. The second block 92 and the first block 81 are closely attached to the upper side area of the composite layer of the diamond composite sheet required, and then drive the clamped diamond composite sheet to move downward, so that the composite layer to be cobalt-removed is immersed in the strong acid. By making the second block 92 and the first block 81 closely attached to the diamond composite sheet in advance, it can be avoided that when the diamond composite sheet enters the strong acid solution, the liquid level will splash out the strong acid solution through the gap between the positioning tube 72 and the composite sheet and contact the cemented carbide layer to cause damage to the cemented carbide, and it can also be avoided that the strong acid solution brought out when the diamond composite sheet leaves the liquid level enters the gap between the positioning tube 72 and the diamond composite sheet to corrode the cemented carbide;

[0047] After the cobalt removal is completed, start the first hydraulic cylinder 5 to drive the diamond composite sheet to leave the liquid level, and then continue to start the two second hydraulic cylinders 80 to push the meshing teeth 377 to overcome the resistance of the tension spring (the state at this time is as Figure 7 shown, Figure 7 for continuing to push against the resistance of the tension spring, that is, the state diagram after the tension spring is stretched) to move in a direction away from the two second hydraulic cylinders 80 until when the meshing teeth 377 are separated from the rotating gear 74, the rotating gear 74 will rotate and reset under the action of the first torsion spring. At the same time of resetting, the rotating gear 74 will drive the diamond composite sheet to rotate together, so that the excess strong acid solution remaining on the diamond composite sheet can be thrown out as much as possible by centrifugal force, avoiding that when the diamond composite sheet is taken out, the remaining strong acid solution drips onto the external equipment or the operator to cause losses.

[0048] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
