Description

Technical Field

[0001] This utility model relates to the field of soft magnetic material processing technology, specifically to a sintering and curing device for soft magnetic materials. Background Technology

[0002] Soft magnetic materials are a class of materials with high permeability and low magnetic loss, and are widely used in power electronics, communications, automotive electronics and other fields. In the production process of soft magnetic materials, sintering and curing is a key step that directly affects the magnetic and mechanical properties of the product. Existing sintering and curing equipment still has some problems. Therefore, it is particularly important to develop a sintering and curing equipment for soft magnetic materials.

[0003] Referring to the CN222317706U publication number, a sintering and curing device for soft magnetic materials includes a furnace body with a furnace opening at the front and a furnace door at the opening. A heating element is installed inside the furnace, and a lock is installed between the furnace door and the furnace body. The lower end of the furnace body has multiple air inlets communicating with its interior, and the upper end of the furnace body has multiple air outlets communicating with its interior. Its simple structure allows protective gas to be introduced into the furnace body from the lower end through multiple air inlets, and the protective gas inside the furnace body is discharged through the air outlets at the top. This ensures a good protective atmosphere inside the furnace, and volatile components generated inside the furnace are promptly carried away by the protective gas, thus preventing oxidation of the heated material. As can be seen from the above, although this device can be widely used, it is generally not convenient to monitor the sintering and curing components comprehensively, which still presents certain inconveniences during use and often causes problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sintering and curing device for soft magnetic materials, comprising a curing chamber, a support frame installed at the bottom of the curing chamber, a servo motor installed at the top of the support frame, the bottom end of the servo motor extending to the inner side of the support frame and having a screw, the bottom end of the screw being rotatably connected to the bottom of the support frame, a guide rod fixed inside the support frame on one side of the screw, a nut seat threaded onto the outer wall of the screw, the nut seat being movably connected to the guide rod, a support frame installed on the outer wall of the nut seat, a portal frame installed at the top of the support frame, a geared motor installed at the top of the support frame inside the portal frame, the top of the geared motor extending to the outside of the portal frame and having a placement tray installed, a sintering tank installed at the top of the placement tray, a tank lid installed at the top of the sintering tank, a top frame provided on the top of the curing chamber above the support frame, a camera installed on the outer wall of the top frame, a control panel installed on the surface of the curing chamber, and the output terminal of the microcontroller inside the control panel being electrically connected to the camera and the input terminal of the servo motor respectively.

[0008] Preferably, each corner of the curing chamber is equipped with a support leg, and a door is installed on the outer wall of one side of the curing chamber via a hinge, so that the curing chamber can be opened and closed.

[0009] Preferably, a rectangular base frame is provided on the outer wall of the curing chamber away from the door, and a rectangular limiting frame is installed on the outer wall of the rectangular base frame.

[0010] Preferably, a baffle is movably installed inside the movable cavity, and the top end of the baffle extends to the outside of the movable cavity and is equipped with a pull handle, so that the baffle can be pulled up and down.

[0012] (1) The screw is driven to rotate by a servo motor, so that the nut seat slides on the outer wall of the screw and the guide rod, so that the nut seat drives the sintering tank to move up and down. Then, the sintering tank is driven to rotate by a geared motor through the placement plate. With the camera, the sintering tank can be monitored in all directions, thereby improving the convenience of using the sintering curing equipment.

[0013] (2) By pulling the handle upward, the baffle moves upward inside the movable cavity, which opens the outer wall of the curing chamber at the rectangular base frame position, thus making it easy to observe the sintering and curing status inside the curing chamber.
