Description

Technical Field

[0001] This utility model relates to the field of soft magnetic forming mold technology, specifically a high-precision pressing mold for the production of iron-silicon-aluminum soft magnetic materials. Background Technology

[0002] Soft magnetic materials refer to materials whose magnetization occurs when the coercivity is no greater than 1000 A / m. Typical soft magnetic materials can achieve maximum magnetization with minimal external magnetic field. They possess low coercivity and high permeability. Soft magnetic materials are easily magnetized and demagnetized, and are widely used in electrical and electronic equipment. The most commonly used soft magnetic materials are iron-silicon alloys (silicon steel sheets) and various soft magnetic ferrites.

[0003] However, existing high-precision pressing dies for the production of iron-silicon-aluminum soft magnets have the following problems during use: Since the forming blocks of the pressing dies are mostly of a single integrated structure, when pressing magnetic cores of different structures and sizes is required, a custom-made integral forming block structure is necessary, resulting in high pressing costs. Therefore, corresponding technical solutions need to be designed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision pressing mold for the production of iron-silicon-aluminum soft magnets. It solves the technical problem that the pressing cost of the pressing mold is high because most of the forming blocks of the pressing mold are integrated structures. When it is necessary to press magnetic cores of different structures and sizes, it is necessary to customize an integral forming block structure. This invention meets the actual use requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a supporting cabinet and a fixed top frame. A hydraulic tank is installed on the top of the fixed top frame. A hydraulic assembly is installed inside the hydraulic tank.

A lifting column two is rotatably connected to the bottom of the connecting pipe. A lifting cylinder is arranged between the bottom of the lifting column two and the support cabinet.

[0007] In a preferred embodiment of this utility model, a support leg is installed on the bottom of the support cabinet, a cabinet door is installed on one side of the support cabinet, the fixed top frame is fixed to the top of the support cabinet, and the drive end of the hydraulic component is located at the bottom center of the fixed top frame.

[0008] In a preferred embodiment of this utility model, the pressing plate and the forming mold are on the same vertical line, the cross-section of the first connecting column is a "T" shaped structure, the size of the first connecting column is smaller than the driving end of the hydraulic component, and the rotating tube is movably connected to the first connecting column.

[0009] In a preferred embodiment of this utility model, the inner wall of the rotating tube is threadedly connected to the second connecting column, the rotating ring is rotatably connected to the second connecting column, the connecting side plate is bolted to the outer side of the rotating tube, and the positioning pin is inserted into the inside of the first connecting column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using the mounting plate and connecting column and other components, the forming mold and pressing plate can be easily replaced. When it is necessary to press and form soft magnets of different sizes, it is not necessary to replace the entire forming mold; only the mounting plate needs to be replaced. Furthermore, after forming, the soft magnet can be easily removed from the mold by using the lifting cylinder for easy handling. This improves the convenience of the pressing and forming operation and reduces the cost of using the mold, thereby solving the problem of high pressing costs for pressing molds.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a high-precision pressing mold for the production of iron-silicon-aluminum soft magnets, comprising: a support cabinet 1 and a fixed top frame 6, a hydraulic tank 7 is provided on the top of the fixed top frame 6, a hydraulic component 13 is provided inside the hydraulic tank 7, a connecting column 9 is connected to the drive end of the hydraulic component 13, a rotating tube 12 is provided on the connecting column 9, a connecting column 11 is connected to the bottom of the rotating tube 12, a rotating ring 10 is provided on the outer side of the connecting column 11, two connecting side plates 14 are symmetrically arranged on the top of the rotating ring 10, a plurality of positioning pins 15 are provided on the top of the connecting column 11, and a pressing plate 5 is provided on the bottom of the connecting column 11.

[0020] An operating groove 2 is provided in the middle of the top of the support cabinet 1. Specifically, the function of the operating groove 2 is to facilitate the operation of the connecting pipe 21 and to facilitate the connection between the lifting column 19 and the lifting column 22. Two fixed side blocks 4 are symmetrically arranged on the top of the support cabinet 1. A mold mounting block 3 is arranged between the fixed side blocks 4. A forming mold 20 is arranged in the middle of the mold mounting block 3. An mounting plate 17 is arranged on the outer edge of the top of the forming mold 20. A lifting plate 18 is arranged inside the forming mold 20. A lifting column 19 is arranged on the bottom of the lifting plate 18. A connecting pipe 21 is arranged on the bottom of the lifting column 19. A lifting column 22 is rotatably connected to the bottom of the connecting pipe 21. A lifting cylinder 23 is arranged between the bottom of the lifting column 22 and the support cabinet 1.

[0021] Further improvements include the installation of support legs on the bottom of the support cabinet 1, the installation of a cabinet door on one side of the support cabinet 1, the fixing top frame 6 being fixed to the top of the support cabinet 1, and the drive end of the hydraulic assembly 13 being located at the bottom center of the fixing top frame 6.

[0022] Further improvements include placing the pressing plate 5 and the forming mold 20 on the same vertical line, making the cross-section of the connecting column 9 into a "T" shape, making the size of the connecting column 9 smaller than the drive end of the hydraulic assembly 13, and making the rotating tube 12 and the connecting column 9 a movable connection.

[0023] In a further improvement, the inner wall of the rotating tube 12 is threadedly connected to the connecting post 11, and the rotating ring 10 is rotatably connected to the connecting post 11. Specifically, as shown in... Figure 2 and Figure 3 As shown, the rotating ring 10 can rotate laterally on the connecting post 11, but cannot move longitudinally. Therefore, when the connecting side plate 14 is connected to the rotating tube 12, the rotating tube 12 cannot move longitudinally, thus ensuring the fixation of the rotating tube 12 and ensuring the stable connection between the connecting post 9 and the connecting post 11. The connecting side plate 14 and the outer edge of the rotating tube 12 are connected by bolts, and the positioning pin 15 is inserted into the inside of the connecting post 9.

The bottom structure of the sweeping plate fits the mounting plate 17 and the mold mounting block 3 to sweep the raw material. The center of the mold mounting block 3 is provided with a through hole for use with the forming mold 20. The mounting plate 17 and the top of the mold mounting block 3 are fixedly connected by bolts. Specifically, the ends of the bolts on the mounting plate 17 are all embedded in the mounting plate 17, that is, the top height of the bolts is not higher than the mounting plate 17. The lifting column 19 is movably connected to the bottom of the forming mold 20. The lifting cylinder 23 is installed inside the support cabinet 1. The connecting pipe 21 is threadedly connected to the lifting column 19.

[0025] In use: First, based on the production needs of soft magnets, the pressing plate 5 and forming mold of corresponding size and structure are determined. Then, the pressing plate 5 is placed at the bottom of the connecting post 1 9, and the rotating tube 12 on the connecting post 1 9 is rotated to connect with the connecting post 2 11 by thread. The positioning pin 15 is inserted into the connecting post 1 9 simultaneously, maintaining the position of the connecting post 2 11 until the top of the connecting post 2 11 contacts the connecting post 1 9. After completion, the rotating ring 10 is rotated to adjust the position of the connecting side plate 14, aligning it with the threaded hole. The connecting side plate 14 is then connected to the rotating tube 12 by bolts, keeping the rotating tube 12 fixed. Then, the forming mold 20 is placed on the mold mounting block 3. Simultaneously, the mounting plate 17 moves to the top of the mold mounting block 3 and is fixed to the mold mounting block 3 with bolts. Then, the lifting column 19 and the lifting column 22 are connected by the connecting pipe 21. When pressing, the iron-silicon-aluminum raw material is put into the forming mold 20. The raw material scattered on the mounting plate 17 and the mold mounting block 3 is swept away by the push sweeping component 8. Then, the hydraulic box 7 drives the pressing plate 5 to move down and press the raw material in the forming mold 20 to achieve forming. The lifting cylinder 23 pushes the lifting plate 18 and drives the soft magnet to move out.

[0026] The components of this utility model, including the support cabinet-1, operating groove-2, mold mounting block-3, fixed side block-4, pressing plate-5, fixed top frame-6, hydraulic tank-7, push-sweep assembly-8, connecting column one-9, rotating ring-10, connecting column two-11, rotating tube-12, hydraulic assembly-13, connecting side plate-14, positioning insert-15, mounting plate-17, lifting plate-18, lifting column one-19, forming mold-20, connecting tube-21, lifting column two-22, and lifting cylinder-23, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that most pressing molds have an integrated structure, which leads to high pressing costs when pressing magnetic cores of different structures and sizes. This utility model solves the problem by combining the above-mentioned components, using connecting column one and connecting column two, along with a rotating tube and connecting side plate, to facilitate the loading and unloading of the pressing plate. The mounting plate allows for easy fixing of the molding mold to the mold mounting block, making it convenient to replace molding molds of different sizes and to press soft magnets of different sizes without replacing the entire molding mold.
