Description

Technical Field

[0001] The utility model relates to the technical field of iron core production, in particular to an annealing device for iron core production. Background Art

[0002] In the iron core production process, annealing is a crucial link, which can effectively eliminate the residual stress inside the material, improve the material's organizational structure, and thus enhance the iron core's mechanical properties and processing performance. However, when annealing the iron core through the annealing device, the traditional annealing device usually adopts a static heating method, that is, the raw material is placed inside the box, and the raw material is evenly heated by the heater. However, under the static heating method, the raw material cannot roll autonomously, resulting in a limited heating area, which may cause uneven annealing of the raw material, overheating of some areas and insufficient heating of some areas, thereby affecting the final quality and performance of the iron core. Therefore, we propose an annealing device for iron core production to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide an annealing device for iron core production, which solves the problem that traditional annealing devices usually adopt a static heating method, that is, the raw materials are placed inside a box and the raw materials are evenly heated by a heater. However, in the static heating method, the raw materials cannot roll independently, resulting in a limited heating area, which may cause uneven annealing of the raw materials, excessive heating in some areas and insufficient heating in some areas, thereby affecting the final quality and performance of the iron core.

The placing mechanism comprises a placing box, which is installed inside the box body, a movable block is movably installed at the upper end of the interior of the placing box, a plurality of placing cavities are provided at the upper end of the movable block, a rotating shaft is movably installed at the lower end of the interior of the movable block, and the rotating shaft is movably installed inside the placing box, a plurality of limit blocks are installed outside the rod body of the rotating shaft at the front end, the limit blocks are snap-fitted and connected with the movable blocks, a motor is installed at the rear side of the box body, and the output end of the motor is snap-fitted and connected with the rear end of the rotating shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) In the utility model, when the heater heats and anneals the raw material, the motor drives the movable block to swing on both sides through the rotating shaft, so that the raw material in the placement cavity can roll inside the placement cavity according to the swing of the movable block, so that the raw material can be evenly heated and the production quality of the raw material can be improved. After the raw material is annealed, when the fan blows into the interior of the box through the exhaust hole for cooling, the raw material will still roll with the swing of the movable block to assist the raw material in evenly dissipating heat and improve the heat dissipation efficiency of the raw material.

Then, the motor can drive the rotating shaft to rotate through the locking block. Then, the rotating shaft drives the movable block to rotate through the cooperation of the limit block and the No. 2 limit groove, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The user places several raw materials in the placement cavity 403 respectively, and then the user places the placement box 401 in the box body 1. After the placement of the placement box 401 is completed, the user pushes the rotating shaft 404 to allow the rotating shaft 404 to drive the limit block 409 to separate from the first limit groove 407. At the same time, the rotating shaft 404 also drives the locking block 410 to lock into the inside of the locking groove 411. After the position adjustment of the rotating shaft 404 is completed, the user can close the sealing door 2 and start the heater 3 to start heating and annealing the raw materials. At the same time, the motor 412 will drive the rotating shaft 404 to rotate left and right through the locking block 410, and then the rotating shaft 404 drives the movable block 402 to move forward through the cooperation of the limit block 409 and the second limit groove 408. The raw material is shaken left and right to make it roll inside the placement chamber 403, so that the raw material is evenly heated. After the raw material is annealed, the fan 5 blows air into the main pipe 7 through the air guide pipe 6, and then the air entering the main pipe 7 is blown into the box body 1 along the exhaust hole 8 to cooperate with the rolling raw material to perform heat dissipation. After the raw material is cooled, the user can open the sealing door 2, and then pull the rotating shaft 404, so that the rotating shaft 404 drives the limiting block 409 to insert into the first limiting groove 407, so as to realize the positioning of the rotating shaft 404 and the movable block 402, and at the same time, the locking block 410 is separated from the locking groove 411. Then the user can take out the placement box 401 to take out and replace the raw materials inside it, which is simpler and more convenient.

[0026] The cooperation between the limit block 409 and the first limit groove 407 makes it easy for the user to control the connection or separation of the rotating shaft 404 and the placement box 401.

Then, when the rotating shaft 404 is needed to drive the movable block 402 to shake, the rotating shaft 404 can be pushed to separate the limit block 409 and the first limit groove 407, which is more convenient.

[0027] The limit block 409 and the second limit slot 408 are used to cooperate with the rotating shaft 404 to drive the movable block 402 to rotate or position, so that the movable block 402 can remain stable when the placing box 401 is taken out or placed, and then when the movable block 402 needs to be shaken, the rotating shaft 404 can drive the movable block 402 to rotate left and right through the limit block 409 and the second limit slot 408;

[0028] By setting the engaging block 410 and the engaging slot 411 to be polygonal, the motor 412 can drive the rotating shaft 404 to rotate through the engaging block 410 and the engaging slot 411, thereby improving the overall stability.

[0030] When in use, the user first places several raw materials in the placement cavity 403 respectively, and then the user places the placement box 401 in the box body 1. After the placement of the placement box 401 is completed, the user pushes the rotating shaft 404 to allow the rotating shaft 404 to drive the limiting block 409 to separate from the first limiting groove 407, and at the same time, the rotating shaft 404 also drives the locking block 410 to lock into the inside of the locking groove 411. After the position adjustment of the rotating shaft 404 is completed, the user can close the sealing door 2 and start the heater 3 to start heating and annealing the raw materials. At the same time, the motor 412 will drive the rotating shaft 404 to rotate left and right through the locking block 410, and then the rotating shaft 404 drives the movable block 409 through the cooperation of the limiting block 409 and the second limiting groove 408. 02 is shaken left and right to make the raw material roll inside the placement chamber 403, so that the raw material is evenly heated. Then, after the raw material is annealed, the fan 5 blows air into the main pipe 7 through the air duct 6, and then the air entering the main pipe 7 is blown into the inside of the box body 1 along the exhaust hole 8, and the rolling raw material is used for heat dissipation. Then, after the raw material is cooled, the user can open the sealing door 2, and then pull the rotating shaft 404, so that the rotating shaft 404 drives the limiting block 409 to insert into the inside of the first limiting groove 407, so as to realize the positioning of the rotating shaft 404 and the movable block 402, and at the same time, the locking block 410 is disengaged from the inside of the locking groove 411, and then the user can take out the placement box 401 to take out and replace the raw materials inside it, which is simpler and more convenient.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
