Description

Technical Field

[0001] The present invention relates to the technical field of rework processing, and particularly relates to an annealing device for iron-silicon-aluminum powder materials and a method for using the same. Background Art

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling. The material after annealing can reduce residual stress, stabilize dimensions, reduce deformation and crack tendency, refine grains, adjust the structure, eliminate structure defects, make the material structure and composition uniform, and improve the material properties.

[0003] Iron-silicon-aluminum powder is an important magnetic material. Through annealing processing, the crystal structure of iron-silicon-aluminum powder can be changed from an amorphous state with a ball-milled and broken irregular morphology to a partially ordered state with a flaky morphology. This transformation helps to optimize the arrangement and distribution of grains and improve the overall performance of the material. At the same time, annealing can also eliminate crystal defects and internal stress generated during the preparation process of the material, thereby improving its magnetic properties and physical properties.

[0004] Currently, the equipment commonly used for annealing iron-silicon-aluminum powder is an annealing furnace. The iron-silicon-aluminum powder material can be put into the annealing furnace. However, different from other integral materials, the iron-silicon-aluminum powder material is a powder accumulation body and can be dispersed, while integral materials cannot be separated and can only be annealed directly in the annealing furnace. Then, if the dispersible iron-silicon-aluminum powder material is also annealed directly, it may cause uneven annealing of the iron-silicon-aluminum powder inside the powder accumulation body, and the overall annealing effect of the iron-silicon-aluminum powder material is inconsistent. Therefore, we propose an annealing device for iron-silicon-aluminum powder materials and a method for using the same. Summary of the Invention

[0015] The present invention also provides a method for using an annealing device for iron-silicon-aluminum powder materials, including the following steps: Step 1: Place the iron-silicon-aluminum powder materials inside the inner furnace. Then, the servo motor operates to drive the lead screw to rotate. The outer wall of the lead screw meshes with the inner wall of the first threaded hole. At the same time, through the limitation of the wedge-shaped strip by the wedge-shaped groove, the first movable plate can be made to move into the inner furnace. Through the connection of the connecting strip, the second movable plate moves synchronously until the first movable plate abuts against the inner wall of the inner furnace. At this time, the second movable plate also seals the inner furnace. Turn off the servo motor. Then, turn the first bolt until it separates from the third threaded hole. Then, turn the second bolt until it is inserted into the positioning hole. At this time, due to the setting of the clamping block, the second movable plate cannot be removed from the inner furnace. Close the door of the annealing furnace body. Step 2: The servo motor continues to operate to drive the lead screw to rotate. At this time, since the first movable plate cannot move, the rotation of the lead screw can drive the first movable plate to rotate. The rotation of the first movable plate drives the connecting bar to rotate, which enables the stirring blade to rotate. Thus, the iron-silicon-aluminum powder inside the inner furnace is stirred through the rotation of the connecting bar and the stirring blade. Meanwhile, the rotation of the lead screw drives the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear to rotate, thereby causing the rotating rod to rotate. The rotation of the rotating rod drives the turntable to rotate. Through the limitation of the clamping shaft by the second annular groove, the rotation of the turntable can drive the connecting rod to reciprocate in the L-shaped pipe, so that the piston reciprocates in the L-shaped pipe. When the piston moves outward, at this time, a negative pressure state is formed inside the L-shaped pipe and the connecting cavity, which enables the second spring to be compressed, causing the plugging disc to separate from the first connecting ring. Thus, the hot air inside the annealing furnace body enters the L-shaped pipe through the air inlet pipe. Then, as the piston moves reversely, a positive pressure state is formed inside the L-shaped pipe and the connecting cavity, which enables the chuck to move upward. Therefore, the hot air entering the L-shaped pipe and the connecting cavity enters the bottom inside the inner furnace through the limiting ring, and the heat can be transferred. At the same time, the iron-silicon-aluminum powder at the bottom of the inner wall of the annealing furnace body is blown up. Step 3: After annealing is completed, turn off the servo motor, open the annealing furnace body, then turn the second bolt to separate the second bolt from the positioning hole, and turn the first bolt to screw the first bolt into the third threaded hole. Then turn on the switch of the servo motor to drive the lead screw to rotate. Under the meshing of the lead screw and the first threaded hole, the first movable plate moves inside the inner furnace, so that the first movable plate pushes out the iron-silicon-aluminum powder inside the inner furnace.

[0016] The technical effects and advantages of the present invention: With the setting of the stirring mechanism in the present invention, the rotation of the stirring blade is driven by the rotation of the first movable plate inside the inner furnace, thereby stirring the iron-silicon-aluminum powder inside the inner furnace, increasing the fluidity of the iron-silicon-aluminum powder. Meanwhile, with the cooperation of the air blowing mechanism, the fluidity of the iron-silicon-aluminum powder is further increased, so that the iron-silicon-aluminum powder is heated more evenly, improving the annealing effect of the iron-silicon-aluminum powder.

When the first bolt 307 is separated from the third threaded hole 308 and the second bolt 310 is inserted into the positioning hole 311, the rotation of the lead screw 301 can drive the first movable plate 201 to rotate.

[0029] Among them, the air blowing mechanism is arranged at the bottom of the inner furnace 102. The air blowing mechanism includes a connection cavity 403 opened inside the inner furnace 102. An air outlet mechanism is provided on the inner wall of the connection cavity 403. An L-shaped pipe 401 is fixedly inserted and connected to the inner wall of the annealing furnace body 101.

A second spring 505 is arranged between the blocking plate 504 and the second connecting ring 503. The piston 402 reciprocates in the L-shaped pipe 401. When the piston 402 moves outwards, at this time, a negative pressure state is formed inside the L-shaped pipe 401 and the connection cavity 403, so that the second spring 505 can be compressed, and the blocking plate 504 is separated from the first connecting ring 502, so that the hot air in the annealing furnace body 101 enters the L-shaped pipe 401 through the air inlet pipe 501. Then, as the piston 402 moves in the reverse direction, a positive pressure state is formed inside the L-shaped pipe 401 and the connection cavity 403, so that the chuck 406 moves upwards, so that the hot air entering the L-shaped pipe 401 and the connection cavity 403 enters the bottom inside the inner furnace 102 through the limiting ring 405, and the heat can be transmitted, and at the same time, the iron-silicon-aluminum powder at the bottom of the inner wall of the annealing furnace body 101 can be blown up.

The rotation of the lead screw 301 drives the first bevel gear 701 to rotate. The rotation of the first bevel gear 701 drives the second bevel gear 702 to rotate, so that the rotating rod 603 rotates. The rotation of the rotating rod 603 drives the turntable 602 to rotate. Through the limitation of the clamping shaft 605 by the second annular groove 606, the rotation of the turntable 602 can drive the connecting rod 601 to reciprocate in the L-shaped pipe 401, so that the piston 402 reciprocates in the L-shaped pipe 401, enabling the air blowing mechanism to work stably. The servo motor 704 is electrically connected to the external power supply through an external switch, facilitating the operator to control the servo motor 704 and improving the safety and convenience of operating the servo motor 704.

[0031] The present invention also provides a use method of an annealing device for iron-silicon-aluminum powder materials, including the following steps: Step 1: Place the iron-silicon-aluminum powder materials inside the inner furnace 102. Then, the servo motor 704 works to drive the lead screw 301 to rotate. The outer wall of the lead screw 301 meshes with the inner wall of the first threaded hole 302. At the same time, through the limitation of the wedge-shaped groove 303 on the wedge-shaped strip 304, the first movable plate 201 can be made to move towards the inside of the inner furnace 102. Through the connection of the connecting strip 203, the second movable plate 202 moves synchronously until the first movable plate 201 abuts against the inner wall of the inner furnace 102. At this time, the second movable plate 202 also seals the inner furnace 102. Turn off the servo motor 704. Then, turn the first bolt 307 until the first bolt 307 is separated from the third threaded hole 308. Then, turn the second bolt 310 until the second bolt 310 is inserted into the positioning hole 311. At this time, due to the setting of the clamping block 305, the second movable plate 202 cannot be removed from the inner furnace 102. Close the door of the annealing furnace body 101. Step 2: The servo motor 704 continues to operate to drive the lead screw 301 to rotate. At this time, since the first movable plate 201 cannot move, the rotation of the lead screw 301 can drive the first movable plate 201 to rotate. The rotation of the first movable plate 201 drives the connecting bar 203 to rotate, and then the stirring blade 204 can be driven to rotate. Thus, the iron-silicon-aluminum powder inside the inner furnace 102 is stirred through the rotation of the connecting bar 203 and the stirring blade 204. At the same time, the rotation of the lead screw 301 drives the first bevel gear 701 to rotate, and the rotation of the first bevel gear 701 drives the second bevel gear 702 to rotate, so that the rotating rod 603 rotates. The rotation of the rotating rod 603 drives the turntable 602 to rotate. Through the limitation of the clamping shaft 605 by the second annular groove 606, the rotation of the turntable 602 can drive the connecting rod 601 to reciprocate in the L-shaped pipe 401, so that the piston 402 reciprocates in the L-shaped pipe 401. When the piston 402 moves outwards, at this time, a negative pressure state is formed inside the L-shaped pipe 401 and the connecting cavity 403, so that the second spring 505 is compressed, and the blocking disc 504 is separated from the first connecting ring 502. Thus, the hot air inside the annealing furnace body 101 enters the L-shaped pipe 401 through the air inlet pipe 501. Then, as the piston 402 moves in the reverse direction, a positive pressure state is formed inside the L-shaped pipe 401 and the connecting cavity 403, so that the chuck 406 moves upwards. Thus, the hot air entering the L-shaped pipe 401 and the connecting cavity 403 enters the bottom inside the inner furnace 102 through the limiting ring 405, and the heat can be transferred. At the same time, the iron-silicon-aluminum powder at the bottom of the inner wall of the annealing furnace body 101 is blown up; Step 3: After annealing is completed, turn off the servo motor 704, open the annealing furnace body 101, then turn the second bolt 310 to separate the second bolt 310 from the positioning hole 311, and turn the first bolt 307 to screw the first bolt 307 into the third threaded hole 308. Then turn on the switch of the servo motor 704 to drive the lead screw 301 to rotate. Under the meshing of the lead screw 301 and the first threaded hole 302, the first movable plate 201 moves inside the inner furnace 102, so that the first movable plate 201 pushes out the iron-silicon-aluminum powder inside the inner furnace 102.

10. A method for using an annealing device for iron-silicon-aluminum powder materials according to any one of claims 1-9, characterized in that, It includes the following steps: Step 1: Place the iron-silicon-aluminum powder material inside the inner furnace (102). Then, the servo motor (704) operates to drive the lead screw (301) to rotate. The outer wall of the lead screw (301) meshes with the inner wall of the first threaded hole (302). At the same time, through the limitation of the wedge-shaped bar (304) by the wedge-shaped groove (303), the first movable plate (201) can be made to move towards the inside of the inner furnace (102). Through the connection of the connecting bar (203), the second movable plate (202) moves synchronously until the first movable plate (201) abuts against the inner wall of the inner furnace (102). At this time, the second movable plate (202) also seals the inner furnace (102). Turn off the servo motor (704). Then, turn the first bolt (307) until the first bolt (307) separates from the third threaded hole (308). Then, turn the second bolt (310) until the second bolt (310) is inserted into the positioning hole (311). At this time, due to the setting of the block (305), the second movable plate (202) cannot be removed from the inner furnace (102). Close the door of the annealing furnace body (101). Step 2: The servo motor (704) continues to operate to drive the lead screw (301) to rotate. At this time, since the first movable plate (201) cannot move, the rotation of the lead screw (301) can drive the first movable plate (201) to rotate. The rotation of the first movable plate (201) drives the connecting bar (203) to rotate, so that the stirring blade (204) can rotate. Thus, the iron-silicon-aluminum powder inside the inner furnace (102) is stirred through the rotation of the connecting bar (203) and the stirring blade (204). At the same time, the rotation of the lead screw (301) drives the first bevel gear (701) to rotate, and the rotation of the first bevel gear (701) drives the second bevel gear (702) to rotate, so that the rotating rod (603) rotates. The rotation of the rotating rod (603) drives the turntable (602) to rotate. Through the limitation of the second annular groove (606) on the clamping shaft (605), the rotation of the turntable (602) can drive the connecting rod (601) to reciprocate in the L-shaped pipe (401), so that the piston (402) reciprocates in the L-shaped pipe (401). When the piston (402) moves outwards, at this time, the inside of the L-shaped pipe (401) and the connecting cavity (403) is in a negative pressure state, so that the second spring (505) is compressed, and the blocking plate (504) is separated from the first connecting ring (502). Thus, the hot air in the annealing furnace body (101) enters the L-shaped pipe (401) through the air inlet pipe (501). Then, as the piston (402) moves in the reverse direction, the inside of the L-shaped pipe (401) and the connecting cavity (403) is in a positive pressure state, so that the chuck (406) moves upwards. Thus, the hot air entering the L-shaped pipe (401) and the connecting cavity (403) enters the bottom inside the inner furnace (102) through the limiting ring (405), so that the heat can be transferred, and at the same time, the iron-silicon-aluminum powder at the bottom of the inner wall of the annealing furnace body (101) is blown up. Step 3: After annealing is completed, turn off the servo motor (704), open the annealing furnace body (101), then turn the second bolt (310) to separate the second bolt (310) from the positioning hole (311), and turn the first bolt (307) so that the first bolt (307) is screwed into the third threaded hole (308). Then turn on the switch of the servo motor (704) to drive the lead screw (301) to rotate. Thus, under the engagement of the lead screw (301) and the first threaded hole (302), the first movable plate (201) moves inside the inner furnace (102), so that the first movable plate (201) pushes out the iron-silicon-aluminum powder inside the inner furnace (102).
