[0017] Beneficial effects

[0018] This invention provides a sintering apparatus for metal-ceramic cutting tools. Compared with the prior art, it has the following advantages:

[0019] 1. The sintering equipment for cutting metal-ceramic cutting tools places the ceramic cutting tools to be sintered in a tool placement slot. The tool placement slot is machined and opened according to the shape of the cutting tool. Then, two hoop rings are fitted over the tool placement slot and connected together with reinforcing bolts. Next, the cross-shaped insert at one end of the center rod is inserted into the first docking shaft at one end of the furnace tube. The support ring contacts the inner wall of the furnace tube to provide support. Then, the sealing cap is fixed to one end of the furnace tube by screws and a buckle is added for auxiliary fixation. The cross-shaped insert at the other end of the center rod also needs to be inserted into the second docking shaft inside the side wall of the sealing cap. Then, the first servo motor is started to drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the first docking shaft to rotate. The first docking shaft then drives the center rod and the sleeve to rotate. In this way, it can be ensured that each cutting tool is heated evenly during sintering. Due to the frictional resistance between the support ring and the inner wall of the furnace tube, plus its own gravity, the center rod will not rotate when it rotates. The diameter of the sleeve is smaller than that of the support ring to ensure that it will not come into contact with or scrape the inner wall of the furnace tube.

[0020] 2. The sintering equipment for the metal-ceramic cutting tool starts by activating the second servo motor, which drives the lead screw to rotate. Under the restriction of the limit rod, the lead screw causes the nut block to move linearly along the lead screw. The nut block then drives the heating furnace and casters to move. In this way, the heating furnace can uniformly calcine each part of the furnace tube in turn. The casters and limit rods provide support for the heating furnace, thereby reducing the load pressure on the lead screw. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 6 This application provides a sintering apparatus for a metal-ceramic cutting tool, including an assembly plate 1. A rotating calcining assembly 2 is disposed inside the assembly plate 1. A movable adjustment assembly 3 is disposed on one side of the assembly plate 1. The rotating calcining assembly 2 includes a furnace tube 21, which is fixedly connected inside two assembly plates 1. The rotating calcining assembly 2 also includes a central rod 22, with a support ring 23 rotatably connected to the outer wall of the central rod 22. A sleeve column 24 is fixedly connected to the outer wall of the central rod 22. A rotating connection is made inside the side wall of one end of the furnace tube 21. A first docking shaft 26 is connected to the furnace tube 21. Cross-shaped inserts 213 are fixedly connected to both ends of the central rod 22. The first docking shaft 26 is rotatably connected to the inner side wall of one end of the furnace tube 21. A sealing cap 212 is threadedly connected to one end of the furnace tube 21. A second docking shaft 214 is rotatably connected to the inner side wall of the sealing cap 212. Two cross-shaped inserts 213 are correspondingly inserted into the first docking shaft 26 and the second docking shaft 214. A support ring 23 is movably connected to the inner wall of the furnace tube 21. A worm gear 27 is fixedly connected to one end of the first docking shaft 26. A tool placement groove 25 is provided inside the sleeve column 24. A hoop ring 215 is movably connected to the outer wall of the sleeve column 24. Reinforcing bolts 216 are threadedly connected to the inner sides of the two hoop rings 215. A first auxiliary block 28 and a second auxiliary block 211 are fixedly connected to one side of the furnace tube 21. A worm gear 29 is rotatably connected to one side of the first auxiliary block 28. The worm gear 29 meshes with a worm wheel 27. A first servo motor 210 is fixedly installed inside the second auxiliary block 211. The output shaft of the first servo motor 210 is fixedly connected to one end of the worm gear 29.

[0032] In practice: The ceramic cutting tool to be sintered is placed in the tool placement groove 25, which is machined and opened according to the shape of the tool. Then, two hoop rings 215 are fitted over the tool placement groove 25 and connected together with reinforcing bolts 216. Next, the cross-shaped insert 213 at one end of the center rod 22 is inserted into the first connecting shaft 26 at one end of the furnace tube 21. The support ring 23 contacts the inner wall of the furnace tube 21 to provide support. Then, the sealing cap 212 is fixed to one end of the furnace tube 21 by screwing and a buckle is added for auxiliary fixation. The cross-shaped insert 213 at the other end of the center rod 22 should also be inserted into the sealing cap 212. Inside the second docking shaft 214 inside the side wall of 12, the first servo motor 210 is then started, which drives the worm gear 29 to rotate. The worm gear 29 then drives the worm wheel 27 to rotate, which in turn drives the first docking shaft 26 to rotate. The first docking shaft 26 then drives the center rod 22 and the sleeve column 24 to rotate. This ensures that each tool is heated evenly during sintering. Because the support ring 23 itself has frictional resistance when it contacts the inner wall of the furnace tube 21, and due to its own gravity, the center rod 22 will not rotate when it rotates. The diameter of the sleeve column 24 is smaller than that of the support ring 23 to ensure that it will not come into contact with or scrape the inner wall of the furnace tube 21.

[0033] Reference Figures 1 to 6 In one aspect of this embodiment, the movable adjustment assembly 3 includes a heating furnace chamber 31 that encloses the furnace tube 21. A nut block 32 is fixedly connected to the bottom of the heating furnace chamber 31, and casters 33 are rotatably connected between the inner walls of the nut block 32. A lead screw 34 is rotatably connected between two assembly plates 1, and the lead screw 34 is threadedly connected to the inside of the nut block 32. A limit rod 35 is also fixedly connected between the two assembly plates 1, passing through the nut block 32 and movably connected thereto. The movable adjustment assembly 3 also includes a second servo motor 36, the output shaft of which is fixedly connected to one end of the lead screw 34.

[0034] In practice: by starting the second servo motor 36, the lead screw 34 is driven to rotate. Under the restriction of the limit rod 35, the nut block 32 moves linearly along the lead screw 34. The nut block 32 then drives the heating furnace 31 and the casters 33 to move. In this way, the heating furnace 31 can uniformly calcine each part of the furnace tube 21 in turn. The casters 33 and the limit rod 35 both provide support for the heating furnace 31, thereby reducing the load pressure on the lead screw 34.

[0035] All electrical devices in this plan are powered by an external power source.

[0036] Working principle: During the sintering of ceramic cutting tools, the ceramic cutting tool to be sintered is first placed in the cutting tool placement groove 25. This cutting tool placement groove 25 is specially machined and opened according to the specific shape of the cutting tool, and can fit the cutting tool well.

[0037] Next, two clamping rings 215 are fitted onto the outside of the tool placement slot 25 and secured with reinforcing bolts 216. This ensures the tool is stable within the placement slot, preventing wobbling or displacement during subsequent operations.

[0038] Subsequently, the cross-shaped insert 213 at one end of the center rod 22 is inserted into the first mating shaft 26 at one end of the furnace tube 21. At this time, the support ring 23 is in close contact with the inner wall of the furnace tube 21, providing good support and ensuring the stability of the center rod 22 inside the furnace tube. Afterwards, the sealing cap 212 is fixed to one end of the furnace tube 21 by screwing, and a clip is added for auxiliary fixing to further enhance the stability of the connection. Simultaneously, the cross-shaped insert 213 at the other end of the center rod 22 is accurately inserted into the second mating shaft 214 inside the side wall of the sealing cap 212.

[0039] After completing the above installation steps, start the first servo motor 210, which will drive the worm gear 29 to rotate. The rotation of the worm gear 29 will drive the worm wheel 27 to rotate, which in turn will drive the first docking shaft 26 to rotate. The rotation of the first docking shaft 26 will then drive the center rod 22 and the sleeve 24 to rotate together. During the sintering process, this rotation method ensures that each tool is heated evenly, avoiding local overheating or uneven heating. Due to the frictional resistance between the support ring 23 and the inner wall of the furnace tube 21, coupled with its own weight, the support ring 23 will not rotate when the center rod 22 rotates. Furthermore, the diameter of the sleeve 24 is smaller than that of the support ring 23, which ensures that the sleeve 24 will not come into contact with or scrape against the inner wall of the furnace tube 21 during rotation, thus avoiding damage to the furnace tube and the tools.

[0040] During the heating process, the second servo motor 36 is activated, which drives the lead screw 34 to rotate. Under the constraint of the limit rod 35, the rotation of the lead screw 34 causes the nut block 32 to move linearly along the lead screw 34. The movement of the nut block 32 causes the heating furnace 31 and the casters 33 to move together. In this way, the heating furnace 31 can adjust its heating position for uniform calcination. Both the casters 33 and the limit rod 35 provide support for the heating furnace 31, thereby reducing the load on the lead screw 34 and ensuring stable operation of the equipment.
