Description

Technical Field

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

[0002] Ferrite core is a high-frequency magnetic material. Its principle is similar to that of silicon steel sheet, but it is mainly used in high-frequency environment. It is mainly composed of metal elements such as iron, manganese and zinc, and is usually called manganese-zinc ferrite. Ferrite core has the characteristics of good high-frequency magnetic properties, strong thermal stability, easy molding, dimensional stability, high magnetic permeability, corrosion resistance, etc., so it is widely used in high-frequency transformers (such as switching power supplies, line output transformers, etc.) and high-frequency magnetic rings (for anti-interference) and other fields.

[0003] In the existing production of small and medium-sized ferrite cores, after being pressed by a pressing machine, since the pressing machine presses the magnetic powder into a ring and then pushes it out for material feeding, excess magnetic powder will be brought out during the pressing and extrusion, resulting in the need to use a mesh plug to sieve the powder when unloading the material in the subsequent process. The operation is more troublesome and affects the production efficiency of the ferrite core.

[0004] Based on this, this device proposes an auxiliary discharging device that quickly cleans the ferrite core through vibration, so as to reduce the subsequent screening process and improve production efficiency. Utility Model Content

[0005] In order to overcome the disadvantage that excess magnetic powder is easily attached to ferrite cores after pressing and forming, resulting in the need for pre-screening to remove the magnetic powder during subsequent production and processing, which affects production efficiency, the utility model provides an auxiliary discharging device for ferrite core production with a vibration cleaning function.

[0006] An auxiliary discharging device for ferrite core production includes a pressing machine, a servo motor, a toggle block and a sieve plate. The sieve plate is rotatably connected to the material outlet end of the pressing machine through a hinge. A torsion spring is provided at the connection between the sieve plate and the pressing machine. The sieve plate is evenly provided with sieve holes. The servo motor is fixed in the pressing machine by bolts. The output shaft of the servo motor is connected to the toggle block. The toggle block can contact and push the sieve plate to form vibration. The ferrite core will be continuously vibrated when passing through the sieve plate, and the magnetic powder attached to the core will be discharged through the sieve holes of the sieve plate.

[0007] A more excellent solution is to further include a bracket and a collecting box, wherein the bracket is fixed to the blanking machine, and the collecting box is fixed in the bracket by sliding embedding, and the collecting box is located below the sieve plate.

[0008] A more excellent solution is to further include a discharge pipe valve, the bottom of the collecting box is in an inverted cone shape and is provided with a discharge port, and the discharge pipe valve is threadedly sleeved on the outside of the discharge port for sealing.

[0009] A more excellent solution is to further include a shock-absorbing pad, which is arranged on the end surface of the sieve plate.

[0010] A more excellent solution is to further include a buffer plate, which is rotatably connected to the lower end of the sieve plate.

[0011] A more excellent solution is to further include an auxiliary roller, which is rotatably arranged on the side of the shifting block and can contact and push the sieve plate.

[0012] A more excellent solution is to also include an observation window. The side of the collection box is provided with an observation window, and the observation window is made of a transparent acrylic plate material.

[0013] The utility model has the following advantages: the sieve plate is docked with the material outlet end of the blanking machine, and the servo motor is turned on to drive the toggle block to rotate continuously. The toggle block will continuously push the sieve plate to cause it to vibrate slightly, and the magnetic powder attached to the ferrite core will be detached under the continuous vibration. Compared with the existing production process, the device achieves the effect of pre-treating the attached magnetic powder, reduces the subsequent screening process, and helps to improve the production efficiency of the ferrite core.

It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0020] Embodiment: An auxiliary discharging device for producing ferrite cores, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a pressing machine 1, and also includes a servo motor 2, a toggle block 3 and a sieve plate 4. The sieve plate 4 is rotatably connected to the material outlet end of the pressing machine 1 through a hinge. Since the sieve plate 4 is inclined, the ferrite core will be transmitted through the sieve plate 4. A torsion spring 5 is provided at the connection between the sieve plate 4 and the pressing machine 1. Sieve holes 6 are evenly opened on the sieve plate 4. The servo motor 2 is fixed in the pressing machine 1 by bolts. The output shaft of the servo motor 2 is connected to the toggle block 3. The toggle block 3 can contact and push the sieve plate 4 to form vibration. The ferrite core will be continuously vibrated when passing through the sieve plate 4, and the magnetic powder attached to the core will be discharged through the sieve holes 6 of the sieve plate 4.

[0021] like Figure 1 and Figure 3 As shown, it also includes a bracket 7 and a collecting box 8. The bracket 7 is fixed to the blanking machine 1. The collecting box 8 is fixed in the bracket 7 by sliding embedding. The collecting box 8 can be slid out for internal cleaning. The collecting box 8 is located below the sieve plate 4.

[0022] like Figure 3 and Figure 4 As shown, a discharge pipe valve 9 is also included. The bottom of the collecting box 8 is inverted cone shape and is provided with a discharge port. The discharge pipe valve 9 is threadedly sleeved on the outside of the discharge port to seal it.

[0023] like Figure 1 and Figure 4 As shown, a shock-absorbing pad 10 is also included. The shock-absorbing pad 10 is arranged on the end surface of the sieve plate 4. The shock-absorbing pad 10 can effectively reduce the collision of the ferrite core in the sieve plate 4 and reduce the occurrence of scratches.

[0024] like Figure 1 and Figure 4 As shown, a buffer plate 11 is also included. The buffer plate 11 is rotatably connected to the lower end of the sieve plate 4. The buffer plate 11 can dock with the lower end of the sieve plate 4 to extend the transportation path of the ferrite cores, making it easier for staff to collect and process the ferrite cores.

[0025] like Figure 1 and Figure 4 As shown, an auxiliary roller 12 is also included. The auxiliary roller 12 is rotatably set on the side of the toggle block 3. The auxiliary roller 12 can contact and push the sieve plate 4. The auxiliary roller 12 can greatly reduce the friction coefficient between the toggle block 3 and the bottom of the sieve plate 4, so that the vibration frequency of the sieve plate 4 is smoother and more regular, thereby improving the magnetic powder removal efficiency.

[0026] like Figure 1 and Figure 4As shown, an observation window 13 is also included. The side of the collection box 8 is provided with an observation window 13. The observation window 13 is made of a transparent acrylic plate material and has high light transmittance. The staff can observe the amount of magnetic powder in the collection box 8 through the observation window 13 to clean it up in time.

[0027] Working principle: After the pressing machine 1 is turned on, the ferrite core is moved from the material outlet end of the pressing machine 1 to the sieve plate 4. Since the sieve plate 4 is inclined, the ferrite core will be transmitted through the sieve plate 4. During this period, the servo motor 2 is turned on to drive the toggle block 3 to rotate. The toggle block 3 continuously pushes the sieve plate 4 to make it vibrate slightly. The magnetic powder attached to the ferrite core will be detached under continuous vibration, and the magnetic powder will fall into the collection box 8 through the sieve hole 6 of the sieve plate 4. The ferrite core after the external magnetic powder is cleaned by vibration is discharged from the sieve plate 4 and the buffer plate 11, and the staff can collect them uniformly on the right side of the device.
