Description

Technical Field

[0001] This utility model relates to the field of cutting tool manufacturing technology, and in particular to a cemented carbide cutting tool coating machine. Background Technology

[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and binder metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at 500℃, and it still has very high hardness at 1000℃. Cemented carbide is widely used as a cutting tool material, such as turning tools, milling cutters, planing tools, drills, boring tools, etc.

[0003] In order to improve the utilization efficiency of coatings and avoid waste, multiple blades are usually sprayed simultaneously in the existing technology. During the spraying process, the blades need to be placed in a sealed box. After the spraying is completed, the blades are removed before the next set of blades can be fixed and installed. After the fixing is completed, the blades are sent back into the box. This will result in low spraying efficiency. Utility Model Content

[0035] An outer cover 101 is mounted on a frame 1. The upper end of the outer cover 101 has a first convex housing 51 and a second convex housing 52. Both the spraying mechanism and the drying mechanism are mounted on the outer cover 101. The spraying mechanism includes a first nozzle 81 and a pump 10. The first nozzle 81 is slidably mounted inside the first convex housing 51. The pump 10 is mounted on the first convex housing 51, and its output end is connected to the first nozzle 81 via a first flexible hose, connecting the input end of the pump 10 to the paint tank.

A vent pipe is provided on the outer cover 101, and a filter for gas filtration and purification can be installed on the vent pipe to achieve filtration of the gas inside the outer cover 101.

[0036] The fixed frame mechanism includes a U-shaped frame 6 and multiple rotating seats 7. The multiple rotating seats 7 are equidistantly arranged and rotatably mounted on the U-shaped frame 6. A drive assembly for driving the multiple rotating seats 7 to rotate synchronously is mounted on the U-shaped frame 6. The drive assembly includes a first rack 19, a bolt 22, a second elastic reset assembly, and multiple first toothed rings 21. The U-shaped frame 6 has a mounting groove 602. The first rack 19 is slidably disposed inside the mounting groove 602. The second elastic reset assembly includes a connecting slider 23, a first guide rod 24, and a first spring 25. The connecting slider 23 is connected to the end of the first rack 19, and the first guide rod 24 is connected to the inner wall of the mounting groove 602. The first guide rod 24 movably passes through the connecting slider 23. 3. The first spring 25 is sleeved and installed on the first guide rod 24.

One end of the mounting shaft 20 extends into the inner side of the mounting groove 602. Multiple first toothed rings 21 are respectively installed on multiple mounting shafts 20. Multiple first toothed rings 21 are meshed with the first rack 19. The bolt 22 is threadedly connected to the U-shaped frame 6. Driving the bolt 22 to rotate can push the first rack 19 to move. The movement of the first rack 19 drives the multiple first toothed rings 21 to rotate synchronously, thereby driving the multiple rotating seats 7 to rotate synchronously. The setting of the second elastic reset component allows the first rack 19 to automatically reset when the bolt 22 rotates back.

[0037] The rotating seat 7 has multiple circular grooves 701. A rotating ring 29 is rotatably mounted on the inner side of each of the multiple circular grooves 701.

A ring is provided on the rotating ring 29. The first elastic reset component includes a second guide rod 32 and two second springs 33. The second guide rod 32 is connected to the inner side of the ring. The two clamping blocks 31 are slidably mounted on the second guide rod 32. The two second springs 33 are respectively sleeved and mounted on both ends of the second guide rod 32.

[0038] The rotating seat 7 is equipped with a release mechanism for releasing the clamping state of multiple elastic clamping components. The rotating seat 7 is also equipped with a transmission component that enables multiple rotating rings 29 to rotate synchronously. The transmission component includes a second rack 27 and multiple second toothed rings 28. The rotating seat 7 has a movable groove 702. The second rack 27 is slidably disposed inside the movable groove 702. The push shaft 26 movably passes through the end of the rotating seat 7 and is connected to the second rack 27. The multiple second toothed rings 28 are respectively fixed on the outer periphery of the multiple rotating rings 29, and the multiple second toothed rings 28 are all meshed with the second rack 27. The end of the rotating seat 7 is movably connected to the push shaft 26, and the push shaft 26 is connected to the transmission component.

[0039] The second power assembly is mounted on the outer cover 101 to drive the push shaft 26 to move. The second power assembly includes an electric telescopic rod 16 and two first push plates 15. Two third protruding shells 14 are provided on the side of the outer cover 101. The two first push plates 15 are located inside the two third protruding shells 14 respectively. The electric telescopic rod 16 is mounted on the outer wall of the outer cover 101. Each of the two first push plates 15 is connected to a movable rod 17 that passes through the third protruding shell 14. The two movable rods 17 are connected by a connecting frame 18. The output shaft of the electric telescopic rod 16 is connected to the connecting frame 18. The electric telescopic rod 16 drives the first push plates 15 to move back and forth. The first push plates 15 then push the push shaft 26 to move. With the cooperation of the transmission assembly and the first elastic reset assembly, the reciprocating movement of the tool can be driven.

[0040] Multiple sets of limiting components are installed on the conveyor belt 2 to limit the fixed frame mechanism. Multiple sets of limiting components and multiple baffle plates 3 are arranged at intervals. The limiting components include a limiting plate 13 and multiple limiting pins 12. The multiple limiting pins 12 are arranged side by side on the conveyor belt 2. The limiting plate 13 is connected to the multiple limiting pins 12. The U-shaped frame 6 is provided with multiple limiting holes 601 for the insertion of the multiple limiting pins 12.

[0041] In this embodiment, multiple cutting tools are fixed before spraying. First, the drive assembly drives multiple rotating seats 7 to rotate synchronously, so that the circular groove 701 faces upward, and the two clamping blocks 31 are opened. Then, the tool handle is placed between the two clamping blocks 31. Under the elastic force of the third spring 33, the two clamping blocks 31 are driven to clamp the tool. Then, the other multiple cutting tools are fixed in the same way. After the tool fixing is completed, the limiting hole 601 on the U-shaped frame 6 is aligned with the limiting pin 12 and inserted to complete the limiting work of the fixing frame mechanism. When spraying the cutting tools, the first power assembly drives the conveyor belt 2 to move, that is, drives the fixing frame mechanism to move. When the fixing frame mechanism moves to the position below the first spray head 81, the drive of the conveyor belt 2 is stopped. In order to realize the automatic positioning of the fixing frame mechanism of the conveyor belt 2, an infrared sensor can be installed in a slot on the inner wall of the frame 1. When the conveyor belt 2 is blocked in front of the infrared sensor, the infrared sensor feeds back the signal to the controller. The controller stops the first power unit from driving the conveyor belt 2 until the spraying work is completed. During the spraying process, the electric telescopic rod 16 drives the two first push plates 15 to move. The first push plates 15 can push multiple push shafts 26 to move. The push shafts 26 drive the second rack 27 to move, which in turn drives multiple second toothed rings 28 to rotate. The second toothed rings 28 drive the rotating ring 29 to rotate, so that multiple cutters rotate synchronously to improve the spraying effect on the cutters. After the spraying work is completed, the sprayed cutters move to the position below the second nozzle 82. The drying fan 11 works to generate hot air, which is sprayed out through the second nozzle 82, thereby achieving rapid drying of the coating on the cutter surface. After the drying work is completed, when the fixing frame mechanism starts to move to the position below the conveyor belt 2, the fixing frame mechanism and multiple cutters automatically fall under the action of gravity. The operator can set up a conveyor belt device or a soft pad at the falling position of the fixing frame mechanism to receive it. Then, the cutters are removed from the fixing frame mechanism, and the fixing frame mechanism is recycled.

[0042] Example 2

[0043] like Figure 7 and Figure 8As shown, this embodiment of the carbide tool coating machine, compared with the first embodiment, in this embodiment, the release mechanism includes a pushing component and multiple conical blocks 30. The multiple conical blocks 30 are respectively disposed on the inner side of multiple rotating rings 29. The pushing component includes a second push plate 35 and multiple push rods 34. The multiple push rods 34 are respectively connected to the multiple conical blocks 30 and all move through the side of the rotating seat 7. The second push plate 35 is disposed on the outer side of the rotating seat 7. The multiple push rods 34 all move through the second push plate 35. Each of the multiple push rods 34 is connected to a push block 361 and a limiting block 362. The push block 361 and the limiting block 362 are respectively located on both sides of the second push plate 35. Pushing the push rods 34 to move will drive the conical blocks 30 to move. The conical blocks 30 squeeze the two clamping blocks 31, forcing the two clamping blocks 31 to move away from each other. Pushing the second push plate 35 to move can drive the multiple push rods 34 to move synchronously.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
