Description

Technical Field

[0001] This invention relates to the field of magnetic core forming technology, and in particular to a magnetic core forming apparatus and a forming method thereof. Background Technology

[0002] Ferrite cores are sintered magnetic metal oxides composed of mixtures of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical examples of core materials. Manganese-zinc ferrite is known for its high permeability and high flux density, while exhibiting low loss characteristics. In contrast, nickel-zinc ferrite is characterized by extremely high impedance and low permeability (typically below several hundred). Ferrite cores are widely used in coils and transformers in various electronic devices.

[0003] Current magnetic core forming equipment can typically only press one magnetic core at a time during operation, resulting in low forming efficiency. In addition, the magnetic core needs to be manually removed after molding, which poses a safety hazard. Therefore, a magnetic core forming device and its forming method are proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that most magnetic core forming equipment can only press and form one core at a time during use, resulting in low efficiency in magnetic core forming. Furthermore, the cores need to be manually removed after molding, which can easily lead to danger.

[0005] To solve the above-mentioned technical problems, the present invention provides a magnetic core forming device, including a base plate, a frame fixedly connected to the top of the base plate, a horizontal plate arranged inside the frame, a plurality of stamping rods slidably connected through the interior of the horizontal plate, a connecting frame fixedly connected to the top of the plurality of stamping rods, a plurality of stamping holes for magnetic core molding being formed through the surface of the base plate, the plurality of stamping holes corresponding to the plurality of stamping rods, a sealing block slidably connected inside each of the plurality of stamping holes, a vertical rod fixedly connected to the bottom of each of the plurality of sealing blocks, and a fixing plate connected to the bottom of the plurality of vertical rods.

[0006] A support frame is fixedly connected to the bottom of the base plate, a drive assembly is provided above the support frame, a drive block is provided above the drive assembly, a connecting block is fixedly connected to the bottom of the fixed plate, a transverse groove is provided on the surface of the base plate, a moving assembly is provided inside the transverse groove, and a pusher frame is provided above the moving assembly.

[0007] Preferably, the driving assembly includes a screw, with both ends of the screw rotatably connected to the inner sidewall of the support frame. The driving block is threadedly connected to the outside of the screw. A first motor is fixedly connected to the surface of the support frame. The output end of the first motor passes through the support frame and is fixedly connected to one end of the screw. The first motor can drive the screw to rotate, which facilitates the lateral movement of the driving block and is very convenient.

[0008] Preferably, the inner sidewall of the frame is fixedly connected to two reinforcing plates, one end of which is fixedly connected to the surface of the horizontal plate, which can increase the connection strength between the horizontal plate and the frame and improve the stability of use.

[0009] Preferably, a first inclined surface is formed on one side of the surface of the driving block, and a second inclined surface is formed on the surface of the connecting block, and the first inclined surface and the second inclined surface are slidably connected.

[0010] Preferably, a cylinder is fixedly connected to the top of the frame, and the output end of the cylinder passes through one end of the frame and is fixedly connected to the top of the connecting frame. The connecting frame can be driven by the cylinder, making it more convenient to use.

[0011] Preferably, the moving component includes a second motor, which is fixedly connected to the inner wall of the transverse groove. A stud is fixedly connected to the output end of the second motor. One end of the stud is rotatably connected to the inner wall of the transverse groove. A moving block is threadedly connected to the outside of the stud. The top of the moving block is fixedly connected to the bottom of the pusher frame. The second motor drives the stud to rotate, which facilitates driving the moving block and helps to remove the formed magnetic core after the pusher frame moves.

[0012] The molding method of this magnetic core specifically includes the following steps:

[0013] S1. Place the magnetic core material to be stamped into the stamping hole, start the cylinder, and the cylinder drives the stamping rod through the movement of the connecting frame, thereby applying pressure to the material and stamping it into a magnetic core block.

[0014] S2. After stamping is completed, turn on the first motor. The first motor drives the screw to rotate. After the screw rotates, it can drive the drive block to move. After the drive block moves, it can squeeze the connecting block to move. After the connecting block moves, it pushes the fixing plate to move. After the fixing plate moves, it drives the vertical rod to move. After the vertical rod moves, it can push the sealing block to move and eject the formed magnetic core block.

[0015] S3. Turn on the second motor. The second motor drives the stud to rotate. After the stud rotates, it can drive the moving block to move, so that the pusher frame can be moved to push out the stamped magnetic core.

[0016] The beneficial effects of this invention are as follows:

[0017] By configuring the above-mentioned structure, the present invention can drive multiple stamping rods to move under the drive of a cylinder, thereby facilitating the simultaneous stamping of multiple magnetic core bodies. In addition, under the drive of the first motor, the stud can push out the stamped magnetic core, which effectively avoids the dangers that may be encountered when manually removing the magnetic core, ensures the safety of installation, and enhances its practical application value.
