The sintered diamond tool is formed by mixing and sintering metal powder with diamonds, and the interface between the embedded diamond and the metal powder is not infiltrated, and the bonding strength is also relatively low.

[0003] The new generation of diamond tools is mainly single-layer diamond tools using brazing process. The high-temperature filler metal makes the filler metal diffuse and metallurgically react between the diamond particles and the matrix metal, thereby obtaining an overlayer rich in carbides, improving the holding force of the matrix on the diamond particles, and improving the bonding strength between the abrasive particles and the filler metal and the matrix.

[0068] Specifically, the limiting block 211 is carved with a groove, which is convenient for the engagement of the fixed rack 210 and the drive gear 215, so that the sliding of the limiting block 211 will not be affected by the fixed rack 210, and then the sliding of the first sealing plate 202 and the second sealing plate 203 is facilitated.

[0069] As shown in Figure 15 a pair of fixed support frame 212 is fixed on the side of the first sealing plate 202 away from the second sealing plate 203, which is used to protect and support the fixed support frame 212, so that the fixed support frame 212 will not fall off or shake, and the stability of the fixed support frame 212 is improved.

The other end of the transmission support rod 214 is fixedly connected with the drive gear 215 which is engaged with the fixed rack 210, which is used to drive the movement of the fixed support frame 212 after rotation, and then drive the sliding of the first sealing plate 202. The transmission support rod 214 and the fixed support frame 212 are connected with the fixed bearing 216, so that the rotation of the transmission support rod 214 will not be affected by the fixed support frame 212, and then the mutual engagement of the drive gear 215 and the fixed rack 210 will not be affected.

[0071] As shown in Figures 2 to 7As shown, the cooling frame 201 is provided with a water channel 217 for conveying cooling water, the water conveying pipe 304 is inserted into the water channel 217, and a pair of nozzles 218 are installed on the side wall of the water channel 217 for spraying cooling water, thereby facilitating rapid cooling of the diamond drill bit and shortening the cooling time and improving the efficiency.

[0072] As shown in the figure, Figures 2 to 9 The water conveying mechanism 3 is arranged below the cooling frame 201, and the water conveying mechanism 3 includes a storage tank 301 for storing cooling water, facilitating timely extraction and use, and facilitating the use of workers. The water pump 302 is installed on the storage tank 301 for pumping cooling water to provide power for spraying cooling water, and the water pump 302 is connected with the water suction pipe 303 and the water conveying pipe 304, which are used for conveying cooling water, and the other end of the water suction pipe 303 is inserted into the storage tank 301.

[0077] Working principle: the worker will need to put the material brazing in the fixed base 204, and then turn the jackscrew 208, through the jackscrew 208 to fix it, so that it will not be in the case of shaking, and then through the control box 4 to start the motor 213;

[0078] After the motor 213 starts to drive the drive gear 215 through the transmission support rod 214, the rotation of the drive gear 215 will be fixed due to the fixed rack 210, so that the drive gear 215 drives the fixed support frame 212 to move, and then drives the first sealing plate 202 and the second sealing plate 203 to move towards the brazing equipment furnace 1, and then heats the brazing equipment furnace 1 to the material to be processed. The heat in the brazing equipment furnace 1 will not be dissipated through the cooling frame 201;

[0079] After brazing, the worker starts the motor 213 again, and reverses the motor 213 to drive the fixed support frame 212 to move, and then makes the first sealing plate 202 and the second sealing plate 203 slide into the cooling frame 201, realizing the function of moving the blank out of the brazing equipment furnace 1, facilitating cooling. And at this time, due to the sealing of the second sealing plate 203, the heat in the brazing equipment furnace 1 will not leak. At this time, the worker first fixes the workpiece to be processed in the other fixed base 204, and then starts the corresponding fixed support frame 212, so that the other workpiece can enter the brazing equipment furnace 1, and then the processing and cooling will not affect each other, improving the production efficiency;

[0080] The blank removed from the brazing equipment furnace 1, the worker starts the water pump 302 through the control box 4, and then makes the water pump 302 able to pump out the water flow through the water pump 303, and then enters the water tank 217 through the conveying water pipe 304, and then is sprayed out through the nozzle 218. The sprayed water flow can quickly cool the blank, improving the cooling efficiency of the blank. The water flow can flow downward through the communication pipe 308, and finally is filtered back into the brazing equipment furnace 1 through the filter 309, facilitating the use of the worker, and also facilitating the reuse, reducing the waste of resources.
