Description

Technical Field

[0001] The invention relates to the technical field of diamond cutting blade processing, in particular to a precision processing device for a diamond dicing knife. Background Art

[0002] Diamond scribers are diamond cutting blades, which are cutting tools widely used in the processing of hard and brittle materials such as stone, concrete, prefabricated panels, new and old roads, and ceramics. Diamond cutting blades are mainly composed of two parts: the base and the blade head. The base is the main supporting part of the bonded blade head, while the blade head is the cutting part during use. The blade head will be continuously consumed during use, while the base will not. The reason why the blade head can play a cutting role is that it contains diamond. Diamond is the hardest substance at present. It rubs and cuts the object to be processed in the blade head, and the diamond particles are wrapped in metal inside the blade head. In the processing of diamond cutting blades, the diamond particles are mixed with metal powder and need to be pressed into shape with the base by a molding machine. The pressed diamond cutting blade can be processed after sintering.

[0003] However, there are still some problems with the existing molding machines: when the existing molding machines are in use, the metal powder is prone to uneven distribution, resulting in poor bonding between the matrix and the metal powder, causing the quality of the diamond cutting blade to fail to meet the standards. At the same time, when pressing the diamond cutting blade, the matrix and the metal powder need to be fed in sequence. This process is relatively complicated, time-consuming and labor-intensive, resulting in reduced processing efficiency. Summary of the invention

[0022] Working principle: When using the processing device, in the powder feeding mechanism 7, a person adds metal powder and diamond particles of corresponding proportion into the mixing barrel 704, and the first stepper motor 706 on the horizontal plate 705 drives the mixing shaft 707 to rotate, thereby uniformly mixing the metal powder and diamond particles; In the substrate conveying mechanism 3, personnel open the top cover 307, put the substrates into the substrate placing cylinder 306 in turn, then cover the top cover 307, insert the center column connected to the top cover 307 into the center of the substrate, and the substrate conveying box 304 has a thickness that can only hold a single substrate. The electric slide rail 301 connected to the support plate 302 drives the support frame 303 to move, thereby driving the movement of the substrate conveying box 304. At this time, the third electric cylinder 305 drives the substrate push plate 312 to push the substrate to move, and the substrate moves to the bottom of the electromagnet 310 and is adsorbed. At this time, the fourth electric cylinder 309 drives the electromagnet 310 to move downward, thereby adsorbing the substrate and moving it downward to the top of the substrate placing column 213 for placement; At this time, the fifth electric cylinder 6 on the fixed platform 5 drives the powder feeding mechanism 7 to move onto the base 202. At this time, the bottom end of the lower hopper 714 is aligned with the U-shaped mounting seat 211, and the solenoid valve 715 is opened, thereby introducing the mixed powder in the mixing cylinder 704 into the metering machine 716. The metering machine 716 discharges the quantitative mixed powder into the lower hopper 714. At this time, the second stepper motor 709 works, and the cone 717 is driven to rotate through the connecting shaft 710, and the powder spreading plate 718 can spread the mixed powder. At the end of the flattening, the scraper rod 724 can scrape off the residual mixed powder on the surface of the lower hopper 714 to avoid material residue. When the powder paving plate 718 spreads the mixed powder, a movable column 720 is inserted into the movable hole opened by the support rod 719. The movable column 720 is rotatably connected to a clamping wheel 721 to compress and compact the mixed powder. The movable column 720 is connected to a stopper 722, and the stopper 722 cooperates with the return spring 723 to ensure the compaction operation of the clamping wheel 721 on the mixed powder. After the powder feeding mechanism 7 is reset, in the pressing mechanism 2, the hydraulic pump station 8 supplies pressure to the hydraulic cylinder 206, and the hydraulic cylinder 206 on the top plate 205 drives the movable plate 208 to move downward, and the sliding sleeve 207 slides along the guide column 204, and the forming pressing column 217 connected to the connecting seat 216 can move downward. At the same time, the forming pressing column 217 acts on the substrate on the substrate placement column 213 while pressing the mixed powder. The second electric cylinder 215 drives the U-shaped forming seat 212 to move upward, and then presses the mixed powder to ensure that the substrate and the mixed powder are fully combined. After the diamond cutting blade is pressed and formed, the first electric cylinder 214 drives the substrate placement column 213 to move upward to lift the diamond cutting blade, thereby completing the processing of the diamond cutting blade.
