Description

Technical Field

[0001] The utility model relates to the technical field of presses, in particular to a press for ferrite cores. Background Art

[0002] Ferrite cores are made of dense and homogeneous ceramic-structured non-metallic magnetic materials, with low coercivity, also known as soft ferrite cores. They are composed of iron oxide (Fe2O3) and oxides or carbonate compounds of one or several other metals (such as manganese, zinc, nickel, magnesium). Ferrite raw materials are pressed, then sintered at a high temperature of 1300 °C, and finally machined by a machine to make finished cores that meet application requirements.

[0003] Compared with other types of magnetic materials, the advantages of ferrite are high magnetic permeability, and high resistance and low eddy current loss in a wide frequency range. These material properties make ferrite an ideal material for manufacturing high-frequency transformers, broadband transformers, adjustable inductors, and other applications in high-frequency circuits from 10 kHz to 50 MHz.

[0004] In the prior art, ferrite cores have poor support during pressing, are prone to loosening, and the pressing process is relatively complex, with poor practicability; during the pressing process, raw materials are easily adhered to the inner wall of the mold, which is inconvenient to clean, time-consuming and laborious, and reduces work efficiency. For this reason, we propose a press for ferrite cores. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a press for ferrite cores, which can prevent raw materials from adhering to the inner wall, is convenient to clean, saves time and effort, improves the pressing efficiency, can also ensure a sealed state during the pressing process, avoid raw materials from being pressed and flying, and affect the pressing efficiency; has better support, a simple pressing process, and high practicability, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A press for ferrite cores includes a base and a top plate;

[0007] In the middle of the upper side of the base, a buffer pad is fixedly connected. In the middle of the upper side of the buffer pad, a support block is fixedly connected. Buffer components are arranged at the four corners of the upper side of the buffer pad. On the upper side of the support block, a first pressing plate is fixedly connected. Uniformly distributed pressing grooves are opened on the upper side of the first pressing plate. A limiting sleeve is fixedly connected inside the pressing groove. A column is fixedly connected in the middle of the limiting sleeve. In the middle of the lower side of the top plate, a connecting plate is fixedly connected. A pressing component is arranged in the middle of the upper side of the connecting plate. Two symmetrically distributed connecting rods are fixedly connected to the left and right sides of the connecting plate. Two symmetrically distributed adjusting mechanisms are arranged on the upper side of the base. Guide components are arranged at the four corners between the base and the top plate;

[0008] The adjusting mechanism includes a fixed frame, a T-shaped groove, a T-shaped slider, a cylinder, an auxiliary frame and a U-shaped connecting frame. Two symmetrically distributed fixed frames are fixedly installed on the upper side of the base. A T-shaped groove is formed inside the fixed frame 31.

The inner side of the U-shaped connecting frame is fixedly connected to the T-shaped slider. The outer side of the U-shaped connecting frame is fixedly connected to the connecting rod.

[0009] Starting the cylinder can drive the T-shaped slider to slide up and down in the T-shaped groove, thereby driving the U-shaped connecting frame to slide up and down outside the fixed frame, and then driving the connecting plate and the top plate to move up and down through the connecting rod, realizing the height adjustment of the pressing assembly. The auxiliary frame is used to fix the cylinder and improve the stability of the machine.

[0010] Furthermore, the adjusting mechanism further includes a rectangular chute and a moving slider. Rectangular chutes are formed on the front and rear sides of the fixed frame. A moving slider is slidably connected inside the rectangular chute. The outer side of the moving slider is fixedly connected to the inner side of the U-shaped connecting frame.

[0011] When the U-shaped connecting frame moves up and down, the moving slider can move up and down inside the rectangular chute, playing a role in auxiliary connection and sliding, which is beneficial to improving stability.

[0012] Furthermore, the pressing assembly includes a second pressing plate and a pressing die. The second pressing plate is arranged at the bottom of the connecting plate.

A circular groove for cooperating with the pressing groove is formed at the bottom of the second pressing plate. A vibration motor is fixedly installed on the inner wall of the top of the circular groove. The bottom of the vibration motor is fixedly connected to the pressing die.

[0013] Starting the pressing cylinder can push the second pressing plate downward to make the second pressing plate in close contact with the first pressing plate. At the same time, the pressing die presses the object inside the pressing groove.

[0014] Furthermore, a sealing strip is fixedly connected to the bottom of the second pressing plate. A sealing groove is formed on the upper side of the first pressing plate. The sealing strip is inserted into the sealing groove.

[0015] By moving the connecting plate downward through the adjusting mechanism until the sealing strip is inserted into the sealing groove, it can ensure a sealed state during the pressing process, avoiding the raw material from being pressed and flying, which affects the pressing efficiency.

[0016] Furthermore, the guiding assembly includes guiding rods and guiding sleeves. Guiding rods are fixedly connected to the four corners on the upper side of the base. Guiding sleeves are fixedly connected to the four corners at the bottom of the top plate. The guiding sleeves are used in cooperation with the guiding rods.

The top of the limiting plate is fixedly connected to the damping rod, and the top of the damping rod passes through the buffer cylinder and is fixedly connected to the first pressing plate.

[0019] The arrangements of the buffer cylinder, the limiting plate, the cylindrical compression spring, and the damping rod can reduce the pressure on the first pressing plate during the pressing process. The cylindrical compression spring and the damping rod will play a buffering role, which can improve the service life of the press.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The press for ferrite cores of the present utility model has the following advantages:

[0021] 1. By starting the air cylinder, the T-shaped slider can be driven to slide up and down in the T-shaped groove, thereby driving the U-shaped connecting frame to slide up and down outside the fixed frame. Then, through the connecting rod, the connecting plate and the top plate are driven to move up and down, realizing the height adjustment of the pressing assembly. The auxiliary frame is used to fix the air cylinder to improve the stability of the machine.

[0022] 2. By starting the pressing air cylinder, the second pressing plate can be pushed to move downward, making the second pressing plate in close contact with the first pressing plate.
