Description

Technical Field

[0001] This invention relates to an annealing apparatus, and more particularly to an annealing apparatus for processing molybdenum rods, belonging to the field of molybdenum rod processing technology. Background Technology

[0002] annealing of molybdenum bars is a process that involves heating molybdenum bars to a specific temperature (usually 1000-1200℃), holding them at that temperature, and then slowly cooling them. The main purpose is to eliminate internal stress generated by cold working (such as rolling and drawing), prevent the material from becoming brittle and cracking, restore the material's ductility and toughness, improve subsequent processing performance, refine the grain structure, optimize mechanical properties, stabilize dimensional accuracy, and avoid deformation caused by stress release during use. Annealed molybdenum bars are more suitable for precision machining and high-temperature service scenarios.

[0003] In the prior art, patent application number CN202322343492.1 discloses an annealing device for processing molybdenum rods. In order to solve the problem that during the use of molybdenum rod annealing equipment, the debris and impurities on the surface of the workpiece are easily detached due to the rapid change in surface temperature and thus remain inside the continuous annealing furnace, and the annealed material is not easy to process as a whole, thus affecting the processing efficiency of molybdenum rods, the device uses the movement of multiple conveying rollers to enable automatic conveying of molybdenum rods, thereby achieving automatic conveying of molybdenum rods. At the same time, with the setting of two sealing plates, the contact area between the annealing furnace and the outside air is reduced during use, improving the sealing of the annealing furnace, so as to better concentrate internal heat and thus accelerate the annealing efficiency of molybdenum rods.

[0004] The above-mentioned applications still have shortcomings: During the annealing process, the molybdenum rod can only pass through the coil in a straight line. It is impossible to control the rotation of the molybdenum rod during translation, which can easily cause uneven annealing. In addition, it is not possible to automatically feed and add molybdenum rods at the same time, which is inconvenient. Furthermore, it is not possible to automatically pre-treat the molybdenum rod with spray coating before annealing, resulting in low functionality. During heating, there will be a large heat radiation loss, which will affect the heating rate.

[0005] To address this issue, an annealing apparatus for processing molybdenum bars was designed. Summary of the Invention

[0020] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] like Figures 1-8 As shown, this embodiment provides an annealing device for processing molybdenum rods, including a base 1, an annealing box 2 fixed to the top of the base 1, an electromagnetic induction coil 3 installed inside the annealing box 2, a discharge pipe 4 horizontally fixed to one end of the annealing box 2, the discharge pipe 4 penetrating into the interior of the annealing box 2 and coaxial with the electromagnetic induction coil 3, an argon gas tank 5 installed on the top of the base 1 and below the annealing box 2, the argon gas tank 5 communicating with the interior of the annealing box 2 through a conduit, a feeding box 6 fixed to the end of the annealing box 2 away from the discharge pipe 4, a support ring 7 communicating with the interior of the feeding box 6 fixed to the end of the annealing box 2 near the feeding box 6, a storage box 8 vertically arranged on the top of the feeding box 6 near the end of the annealing box 2, a guide plate 9 provided inside the feeding box 6 and below the storage box 8, a rotating pushing mechanism 10 for continuous feeding of molybdenum rods provided inside the feeding box 6, and a spraying mechanism 11 for uniformly spraying the surface of the molybdenum rods provided below the feeding box 6.

[0022] General working principle: Before use, the molybdenum rods are neatly placed inside the storage box 8, with the bottommost rod falling onto the top of the guide plate 9. During use, the electromagnetic induction coil 3 is energized. The electromagnetic induction coil 3 is made of copper tubing with 15 turns, an inner diameter of φ50mm, and a distance of 5mm from the surface of the molybdenum rod. The operating current is 500A, and the frequency is 10-20kHz. This heats the molybdenum rod to 1100±50℃. The exhaust port of the argon gas cylinder 5 is then opened to inject a protective atmosphere into the annealing chamber 2. Then, the rotating... The pushing mechanism 10 applies a pushing force to the end of the molybdenum rod, moving the molybdenum rod toward the interior of the electromagnetic induction coil 3. At the same time, the rotation of the molybdenum rod is controlled during the pushing process. After the molybdenum rod enters the interior of the support ring 7, the spraying mechanism 11 coats the surface of the molybdenum rod with a silicon carbide high-temperature resistant coating. When the molybdenum rod passes through the support ring 7 and enters the interior of the electromagnetic induction coil 3, it is rotated and heated. The silicon carbide high-temperature resistant coating is used to reduce heat radiation loss and increase the heating rate. After annealing, the molybdenum rod is discharged from the discharge pipe 4.

[0023] In this embodiment, the top center of the guide plate 9 is arc-shaped, and both the top of the guide plate 9 and the inner bottom of the support ring 7 are rotatably mounted with ball bearings.

[0024] Local working principle: 36 φ3mm balls are evenly distributed on the inner bottom of the support ring 7. The balls are embedded in the hemispherical groove of the support ring 7. The groove depth is 1 / 2 of the ball diameter. The balls are coated with polytetrafluoroethylene and have a friction coefficient ≤0.05. The arc groove on the guide plate 9 can limit the molybdenum rod, and the use of balls can reduce the frictional resistance during movement and facilitate pushing.

[0025] In this embodiment, a feeding port 801 is provided on the top of the side of the storage box 8. A sealing plate 803 is hinged to the top of the feeding port 801. A support plate 802 is horizontally fixed on the side of the storage box 8 near the feeding port 801. The inner side of the support plate 802 is arc-shaped.

[0026] Local working principle: When storing molybdenum rods, the molybdenum rods are first placed on top of the support plate 802, and then pushed horizontally towards the inside of the storage box 8. The molybdenum rods push open the sealing plate 803 and finally fall into the inside of the storage box 8.

[0027] In this embodiment, the rotary pushing mechanism 10 includes a slide rod 1001, a fixing plate 1002, a mounting plate 1003, a return spring 1004, a rack 1005, a gear 1006, a partition 1007, an incomplete gear 1008, a rotary motor 1009, and a rotary assembly. The slide rod 1001 is horizontally fixed to the inner end face of the feeding box 6. Two sets of slide rods 1001 are provided, and the positions of the slide rods 1001 are symmetrical. A fixing plate 1002 is fixed between the ends of the slide rods 1001. The fixing plate 1002 is fixed to the inner top of the feeding box 6. Mounting plates are slidably mounted on each slide rod 1001. 1003, a return spring 1004 is provided between the inner end of the mounting plate 1003 and the feeding box 6. A rack 1005 is fixed on the side of the mounting plate 1003 away from the return spring 1004. A gear 1006 is installed on the end of the rack 1005 away from the mounting plate 1003. An incomplete gear 1008 is installed below the rack 1005. The incomplete gear 1008 meshes with the rack 1005. A rotary motor 1009 for driving the incomplete gear 1008 to rotate is installed on both sides of the feeding box 6. A rotary assembly for controlling the rotation of the molybdenum rod when it moves is provided inside the feeding box 6.

[0028] Local working principle: When conveying the molybdenum rod, the rotary motor 1009 is started to control two sets of incomplete gears 1008 to rotate simultaneously. The two sets of incomplete gears 1008 are symmetrically positioned. During the conveying process, only a single incomplete gear 1008 meshes with the rack 1005. When one set of racks 1005 moves horizontally, the gear 1006 at the end of the rack 1005 comes into contact with the end face of the molybdenum rod, transmitting the thrust to the molybdenum rod. When the rack 1005 translates, it stretches the return spring 1004. When the gear 1006 moves into the inside of the support ring 7, the pushing of the molybdenum rod is completed, and the incomplete gear 1008 will separate from the rack 1005. Under the action of the return spring 1004... After rapid reset, once rack 1005 resets, the molybdenum rod falls back down from the storage bin 8. Another incomplete gear 1008 meshes with another rack 1005, pushing the rod again. The two sets of racks 1005 alternately move, continuously conveying the molybdenum rod and improving the processing speed. In the rotary pushing mechanism, the incomplete gear 1008 has 12 teeth and a module of 2. The contact angle between its tooth surface and the tooth surface of rack 1005 is 90°. The reset spring 1004 is a cylindrical helical spring with an elastic coefficient of 50 N / mm and a pre-compression of 15 mm. Gear 1006 and collar 1015 adopt an transition fit (H7 / k6) to ensure that collar 1015 can rotate freely without radial wobble.

[0029] In this embodiment, a partition 1007 is fixed on one side of the mounting plate 1003 near the rack 1005. There is a gap between the two sets of partitions 1007. The top of the partition 1007 and the gear 1006 are on the same horizontal plane. The top of the partition 1007 is coated with a smooth and wear-resistant coating.

[0030] Local working principle: During the pushing process of the molybdenum rod, the partition 1007 blocks the molybdenum rod, which facilitates the reset of the rack 1005 and prevents friction between the gear 1006 and the molybdenum rod.

[0031] In this embodiment, the rotating assembly includes a worm 1010, a worm wheel 1011, a rack 1012, a fixing block 1013, a compression spring 1014, and a collar 1015. The worm 1010 is installed at the output end of the rotary motor 1009. An incomplete gear 1008 is located at the end of the worm 1010. The worm wheel 1011 is meshed with the top of the worm 1010. The rack 1012 is horizontally fixed to the side of the worm wheel 1011. The rack 1012 meshes with the gear 1006. The gear 1006 is rotatably connected to the rack 1005. The fixing block 1013 is fixed at the middle position of the side of the gear 1006. A collar 1015 is sleeved on the outside of the fixing block 1013. Compression springs 1014 are evenly arranged between the outside of the fixing block 1013 and the collar 1015.

[0032] Local working principle: After the molybdenum rod falls to the top of the guide plate 9, it will squeeze the collar 1015, which in turn will compress the compression spring 1014. The collar 1015 is tightly attached to the surface of the molybdenum rod. When the rotary motor 1009 starts to transport the molybdenum rod, it will control the rotation of the worm 1010. The rotation of the worm 1010 will drive the rotation of the worm wheel 1011. The worm wheel 1011 controls the rotation of the rack 1012. Since the rack 1012 is always meshed with the gear 1006, the gear 1006 will also rotate. The rotation of the gear 1006 controls the rotation of the collar 1015, which in turn drives the molybdenum rod to rotate.

[0033] In this embodiment, the outer side of the collar 1015 is uniformly provided with anti-slip textures, and the anti-slip textures are in the form of a grid.

[0034] Local working principle: The use of anti-slip texture increases the frictional resistance between the molybdenum rod and the collar 1015, ensuring that the molybdenum rod can rotate stably.

[0035] In this embodiment, the spraying mechanism 11 includes a paint tank 1101, a nozzle 1102, a spray pipe 1103, and an inflation assembly. The paint tank 1101 is installed at the bottom of the feeding box 6, the nozzle 1102 is installed at the inner top of the support ring 7, the spray pipe 1103 which communicates with the nozzle 1102 is installed inside the paint tank 1101, and the inflation assembly is provided on the side of the paint tank 1101.

[0036] Local working principle: When the molybdenum rod enters the support ring 7, the inflation component inflates the paint tank 1101, squeezing the silicon carbide paint out of the paint tank 1101 and spraying it out of the nozzle 1102. The molybdenum rod can rotate during transport, so the surface of the molybdenum rod is uniformly sprayed. The nozzle 1102 adopts a fan-shaped nozzle with a spray angle of 60° and a working pressure of 0.3-0.5MPa. The paint is made by mixing silicon carbide powder with an average particle size of 5μm and silica sol at a mass ratio of 3:1.

[0037] In this embodiment, a transparent window is provided on the outside of the paint tank 1101, and a liquid level line is provided on the transparent window.

[0038] Local working principle: The transparent window allows for easy observation of the liquid level inside the paint tank 1101, enabling timely addition of raw materials.

[0039] In this embodiment, the inflation assembly includes an air pipe 1104, a cylinder 1105, a one-way air inlet valve 1106, a piston 1107, a connecting rod 1108, a U-shaped rod 1109, and a sleeve 1110. The cylinder 1105 is fixed to the bottom of the feeding box 6. An air pipe 1104 is provided between the bottom end of the cylinder 1105 and the paint box 1101. A one-way valve is provided on the air pipe 1104. A one-way air inlet valve 1106 is provided at the bottom end of the cylinder 1105. A piston 1107 is vertically slidably arranged inside the cylinder 1105. A connecting rod 1108 is hinged to the top of the piston 1107. The U-shaped rod 1109 is fixed between two sets of incomplete gears 1008. A sleeve 1110 is sleeved on the U-shaped rod 1109. The sleeve 1110 is fixedly connected to the connecting rod 1108.

[0040] Local working principle: When conveying molybdenum rods, the rotation of the incomplete gear 1008 will drive the U-shaped rod 1109 to rotate. In the initial state, the U-shaped rod 1109 is located above the incomplete gear 1008. Therefore, when the incomplete gear 1008 rotates, it will control the U-shaped rod 1109 to move down. The U-shaped rod 1109, together with the connecting rod 1108, drives the piston 1107 to move down, injecting the gas inside the cylinder 1105 into the paint box 1101. After the gas inside the cylinder 1105 is completely injected into the paint box 1101, the spraying of the two sets of molybdenum rods can be completed.

[0041] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
