Description

Technical Field

[0001] This utility model relates to the field of magnetic core pressing machine technology, specifically a pressing machine for magnetic core production. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. Ferrite cores are used in coils and transformers of various electronic devices. Magnetic cores are widely used in power electronic devices. Magnetic cores are the basic components of electronic devices and have various shapes and structures. Magnetic cores are generally formed by pressing with molds.

[0003] For example, application number CN202321681004.1 relates to the technical field of ferrite core pressing machines and discloses a ferrite core pressing machine, including a base. A support is fixedly connected to the bottom of the base around its perimeter, and a balance seat is installed on the upper surface of the base. A forming component is installed on the upper surface of the balance seat. A load-bearing frame is fixedly connected to the outer wall of the top of the base, and a fixed seat is fixedly connected to the top of the load-bearing frame. A power distribution box is installed on the top of the fixed seat. Through the setting of a limiting sleeve, forming mold, column, clamp, and locking handwheel, the ferrite core raw material is placed on the inner wall of the forming mold. The limiting sleeve supports the outer wall of the forming mold, preventing deformation under high pressure. The clamp fixes the opening of the forming mold. During the ferrite core pressing process, the locking handwheel is loosened to remove the clamp, opening the forming mold for easy material unloading. The ferrite core has strong support during pressing, preventing loosening and making unloading more convenient and practical.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can address the following shortcomings of existing patents: During use, the ferrite core exhibits poor support during pressing, making it prone to loosening, and the feeding process is complex, resulting in poor practicality. Furthermore, raw materials tend to adhere to the inner wall of the mold during pressing, making cleaning inconvenient, time-consuming, and labor-intensive, thus reducing work efficiency. Although the device uses a vibration motor to separate the adhering raw materials from the inner wall of the mold, it lacks a collection component. This results in poorly pressed raw materials remaining inside the mold, requiring manual collection, which has limitations and affects the efficiency of core pressing. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model provides a pressing machine for producing magnetic cores, including a base 1, a mounting frame 2, a hydraulic transmission device 3, a pressing block 4, and a forming groove 5.

The pressing block 4 is movably connected to the forming groove 5. A mounting plate 6 is provided on the left side of the top of the base 1, and the front and rear sides of the mounting plate 6 are connected to the forming groove 5. Mounting rings 7 are fixedly connected to both sides. A collection cylinder 8 is provided at the bottom of the mounting ring 7.

An inverted conical cylinder 10 is fixedly connected to the bottom of the inner wall of the collection cylinder 8. A hydraulic rod 11 is fixedly connected to the right side of the top of the mounting plate 6. An air extraction pipe 12 is fixedly connected to the top of the mounting ring 7. The left side of the air extraction pipe 12 is connected to an external air extraction pump. A mounting cylinder frame 13 is fixedly connected to the surface of the hydraulic rod 11. A transmission assembly 14 is fixedly connected to the rear side of the bottom of the mounting cylinder frame 13.

[0023] refer to Figure 1 The transmission assembly 14 includes a screw sleeve 141, which is fixedly connected to the rear side of the bottom of the mounting bracket 13. The screw sleeve 141 is internally threaded with a screw rod 142, and the left end of the screw rod 142 is fixedly connected to a motor 143. The left side of the motor 143 is fixedly connected to the mounting bracket 2.

[0024] As a technical optimization of this utility model, by setting a transmission component 14, the motor 143 can drive the screw 142 to rotate after starting, and the screw 142 can drive the screw sleeve 141 to move to the right after rotating, so that the screw sleeve 141 can drive the mounting cylinder 13 to move to the right, and the mounting cylinder 13 can drive the mounting plate 6 to move to the right through the hydraulic rod 11, so that the mounting plate 6 can drive the collecting cylinder 8 to move to the right.

[0025] refer to Figure 3 The top surface of the collecting cylinder 8 is provided with a threaded groove 15, and the inner wall of the mounting ring 7 is fixedly connected with a threaded tooth 16, which is threadedly connected to the threaded groove 15.

[0026] As a technical optimization of this utility model, by setting the threaded groove 15 and the threaded tooth 16, the use of the threaded groove 15 and the threaded tooth 16 makes it convenient for the user to install the collection cylinder 8 at the bottom of the mounting ring 7, and at the same time, it is convenient for the user to disassemble the collection cylinder 8 to collect and process the raw materials collected inside.

[0027] refer to Figure 3 A sealing strip 17 is fixedly connected to the surface of the filter ring 9. There are two sealing strips 17, which are movably connected to the inner wall of the collection cylinder 8 and fit tightly.

[0028] As a technical optimization of this utility model, by setting a sealing strip 17, the use of the sealing strip 17 can reduce the friction between the filter ring 9 and the inner wall of the collection cylinder 8, thereby increasing the airtightness between the filter ring 9 and the collection cylinder 8 and preventing raw materials from entering the exhaust pipe 12 through the installation gap between the filter ring 9 and the collection cylinder 8.

[0029] refer to Figure 3 A cone rod 18 is fixedly connected to the bottom of the filter ring 9, and the cone rod 18 is located at the top of the inverted cone-shaped cylinder 10.

[0030] As a technical optimization of this utility model, by setting a cone rod 18, the cone rod 18 can guide the raw material entering the collection cylinder 8, so that the raw material entering the collection cylinder 8 can fall outward and be blocked by the inverted cone cylinder 10, thus preventing the raw material from falling into the forming groove 5 through the inverted cone cylinder 10.

[0031] refer to Figure 1 A movable sleeve 19 is fixedly connected to the front side of the bottom of the mounting frame 13. A movable frame 20 is movably connected inside the movable sleeve 19. The bottom of the movable frame 20 is fixedly connected to the top of the base 1.

[0032] As a technical optimization of this utility model, by setting up the movable sleeve 19 and the movable frame 20, the cooperation of the movable sleeve 19 and the movable frame 20 can limit the installation cylinder 13, thereby making the installation cylinder 13 more stable and preventing it from shaking when moving.

[0033] refer to Figure 2 The bottom of the surface of the collecting cylinder 8 is provided with anti-slip grooves 21, and there are several anti-slip grooves 21 distributed in a ring at equal intervals.

[0034] As a technical optimization of this utility model, by setting the anti-slip groove 21, the use of the anti-slip groove 21 can increase the friction between the user's hand and the collection tube 8, thereby preventing the user from slipping when rotating the collection tube 8.

[0035] The working principle and usage process of this utility model are as follows: First, connect the suction pipe 12 to the input end of an external suction pump. When it is necessary to clean and collect the raw materials inside the forming tank 5, start the motor 143. The motor 143 will then drive the screw 142 to rotate, causing the screw sleeve 141 to move to the right. This movement of the screw sleeve 141 to the right will then drive the mounting cylinder 13 to move to the right. The mounting cylinder 13, through the hydraulic rod 11, will drive the mounting plate 6 to move to the right, causing the mounting plate 6 to move the collecting cylinder 8 to the right. When the collecting cylinder 8 reaches the top of the forming tank 5, start the hydraulic rod 11, which will then drive the mounting plate 6 downwards. The mounting plate 6 moves downward, causing the collecting cylinder 8 to move downward into the molding tank 5. This allows the air pump to draw air out of the collecting cylinder 8 and the mounting ring 7 through the air extraction pipe 12. The air carries the raw material from the molding tank 5 into the collecting cylinder 8. When the air carrying the raw material enters the collecting cylinder 8, it contacts the cone rod 18 and moves outward. It is then filtered by the filter ring 9 and falls downward, where it is collected by the inverted cone-shaped cylinder 10. This completes the collection of the raw material and achieves the effect of auxiliary collection. At the same time, the user can rotate the collecting cylinder 8, which can then separate from the mounting ring 7 through the threaded groove 15 and threaded teeth 16. This allows the collecting cylinder 8 to be disassembled and the raw material inside to be centrally processed.

[0036] In summary, this magnetic core production pressing machine, by setting up a collection cylinder 8, can collect residual raw materials. This solves the problem that during use, the vibrating motor is used to separate the raw materials adhering to the inner wall of the mold. However, this device does not have a collection component, which causes the raw materials with poor pressing quality to remain inside the mold. The raw materials inside the inner wall still need to be collected manually, which has certain limitations and affects the pressing efficiency of magnetic cores.
