Description

Technical Field

[0001] This utility model relates to the field of ceramic tool processing technology, specifically a coating device for high-hardness coated metal-ceramic tools. Background Technology

[0002] Ceramic knives are tools manufactured using precision ceramics under high pressure, hence the name. They are made using high-tech nanotechnology, with zirconium oxide as the primary raw material, sometimes supplemented with materials such as alumina. The manufacturing process involves pressing zirconium oxide powder at 2000 degrees Celsius under 300 tons of pressure using a mold to form a blade blank, which is then polished with diamond and fitted with a handle to create the finished product. Ceramic knives typically require a coating during processing. This coating usually possesses high hardness and excellent wear resistance, enabling it to withstand greater friction and wear during cutting, reducing the wear rate of the cutting edge, and thus extending the tool's lifespan.

[0003] Currently, the coating of ceramic cutting tools mostly relies on manual spraying with handheld spray guns. This method is inefficient, and the coating materials are often harmful to the human body, requiring operators to wear protective clothing, which makes the entire process time-consuming. Furthermore, manual spraying greatly increases the labor intensity of operators, hindering large-scale, high-efficiency production operations.

[0004] Therefore, this utility model provides a coating device for high-hardness coated metal-ceramic cutting tools to solve the above problems. Utility Model Content

[0017] Beneficial effects

[0018] This invention provides a coating device for high-hardness coated cermet cutting tools. Compared with the prior art, it has the following advantages:

[0019] 1. This coating equipment for high-hardness coated metal-ceramic cutting tools first inserts one end of the ceramic cutting tool into the tool tip slot. Then, the cylinder is activated, which pushes the slide bar forward to move the insert block to the designated position. Simultaneously, the cylinder on the other side pushes another insert block to move, inserting one end of the ceramic cutting tool's handle into the tool handle slot. At this point, the first and second CNC spray guns are activated to spray both sides of the cutting tool simultaneously. Afterward, the cylinder on one side is activated again to reset the insert block, at which point the ceramic cutting tool is inserted into either the tool tip slot or the tool handle slot. The unpainted area at one end will be exposed. As the cylinder on the other side moves continuously, it brings the tip or handle of the blade into the nozzle of the first and second CNC spray guns, allowing for complete coverage spraying. This method requires less manual operation and is more efficient. By starting the servo motor, the worm gear rotates, which in turn drives the worm wheel to rotate. The worm wheel then drives the cylinder and its slide rod to rotate, which in turn drives the insert block to rotate, making the blade rotate and ensuring more even spraying. The slide rod then drives the rotating ring to rotate through the limit strip, which effectively reduces wear during slide rod rotation.

[0020] 2. This coating equipment for high-hardness coated metal-ceramic cutting tools can move a rubber pressure block downwards by activating a small electric actuator, which presses down on the tip and handle of the ceramic cutting tool to fix it in place, preventing the tool from falling off. The rubber pressure block is elastic and will not damage or scratch the tool. Attached Figure Description

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 7 This application provides a coating device for high-hardness coated metal-ceramic cutting tools, including a base 1, a coating component 2 on one side of the base 1, and an auxiliary component 3 inside the coating component 2; the coating component 2 includes a mounting base 21, a worm gear 22 rotatably connected to one side of the mounting base 21, a cylinder 23 fixedly mounted on one side of the worm gear 22, a slide rod 211 fixedly connected to the movable end of the cylinder 23, a limit strip 212 fixedly connected to the outer wall of the slide rod 211, and an insert block 215 fixedly connected to one end of the slide rod 211, one insert block 215 having a blade tip slot 216 inside, and the other insert block 215 having a blade handle slot 217 inside.

[0033] An auxiliary block 24 is fixedly connected to one side of the mounting base 21, and a worm gear 25 is rotatably connected to one side of the auxiliary block 24. The worm gear 25 meshes with a worm wheel 22. A servo motor 26 is fixedly mounted to one side of the mounting base 21, and the output shaft of the servo motor 26 is fixedly connected to one end of the worm gear 25. An assembly plate 213 is fixedly connected to the top of the base 1, and a rotating ring 214 is rotatably connected inside the assembly plate 213. A sliding rod 211 and a limiting strip 212 pass through the rotating ring 214 and are slidably connected to its inner wall. Uprights 27 are fixedly connected to both sides of the base 1, and a horizontal plate 28 is fixedly connected between the two uprights 27. A first CNC spray gun 29 is fixedly mounted at the bottom of the horizontal plate 28, and a second CNC spray gun 210 is fixedly mounted at the top of the base 1.

[0034] In practice: First, insert one end of the ceramic cutting tool into the tip slot 216. Then, activate cylinder 23, which pushes slide rod 211 forward, moving insert block 215 to the designated position. Simultaneously, cylinder 23 on the other side pushes another insert block 215, inserting the handle end of the ceramic cutting tool into handle slot 217. Then, activate the first CNC spray gun 29 and the second CNC spray gun 210 to spray both sides of the tool. Afterward, activate cylinder 23 on one side again to reset insert block 215. At this point, the unsprayed area of ​​the end of the ceramic cutting tool inserted into the tip slot 216 or handle slot 217 will be removed. The blade will be exposed, and as the cylinder 23 on the other side moves continuously, it brings the tip or handle of the blade into the nozzle of the first CNC spray gun 29 and the second CNC spray gun 210, so that the spraying can be carried out to achieve complete coverage spraying. It is more efficient and does not require much manual operation. By starting the servo motor 26, the worm 25 is driven to rotate, the worm 25 drives the worm wheel 22 to rotate, the worm wheel 22 drives the cylinder 23 and its slide rod 211 to rotate, which in turn drives the insert block 215 to rotate, so that the blade rotates and the spraying is more uniform. The slide rod 211 then drives the rotating ring 214 to rotate through the limit bar 212. The rotating ring 214 can effectively reduce the wear of the slide rod 211 when it rotates.

[0035] Reference Figures 1 to 7 In one aspect of this embodiment, the auxiliary component 3 includes a small electric actuator 31, which is fixedly installed inside two insert blocks 215, and a rubber pressure block 32 is fixedly connected to the movable end of the small electric actuator 31.

[0036] In practice: by activating the small electric actuator 31, the rubber pressure block 32 can be moved downward, so that it can press down on the tip and handle of the ceramic knife and fix them tightly, which can prevent the knife from falling off. Moreover, the rubber pressure block 32 is elastic and will not damage or scratch the knife.

[0037] All electrical devices in this plan are powered by an external power source.

[0038] Working principle: When coating the ceramic knife, first insert one end of the ceramic knife into the tip slot 216. Then, activate cylinder 23, which pushes slide rod 211 forward, sending insert block 215 to the designated position. At the same time, cylinder 23 on the other side also pushes another insert block 215 to move, inserting the handle end of the ceramic knife into the handle slot 217.

[0039] At this point, the first CNC spray gun 29 and the second CNC spray gun 210 are activated, simultaneously spraying both sides of the tool. Then, one of the cylinders 23 is activated again, causing the insert block 215 to reset. This exposes the unsprayed portion of the ceramic tool inserted into the tip slot 216 or handle slot 217. As the other cylinder 23 continues to move, it brings the tool tip or handle to the nozzles of the first CNC spray gun 29 and the second CNC spray gun 210, completing the spraying and achieving full coverage of the tool. The entire process requires minimal manual operation, greatly improving work efficiency.

[0040] To achieve a more uniform coating, the servo motor 26 can be activated. The servo motor 26 drives the worm gear 25 to rotate, which in turn drives the worm wheel 22 to rotate, which in turn drives the cylinder 23 and its slide bar 211 to rotate, ultimately causing the insert block 215 to rotate the cutting tool. During this process, the slide bar 211 drives the rotating ring 214 to rotate via the limiting strip 212. The rotating ring 214 effectively reduces the wear generated during the rotation of the slide bar 211.

[0041] To prevent the blade from detaching during the spraying process, a small electric actuator 31 can be activated. This actuator moves the rubber clamp 32 downwards, pressing and securing the tip and handle of the ceramic blade. Because the rubber clamp 32 is elastic, it will not damage the blade or leave scratches.
