[0002] In the field of magnetic material manufacturing, magnetic cores are a key component widely used in electronic components such as transformers and inductors. In the field of magnetic core production technology, magnetic cores can be formed through powder metallurgy stamping. Traditional magnetic core production processes generally use manual or semi-automated methods to feed magnetic powder. This method is unable to automatically feed a certain amount of magnetic powder after each pressing. Traditional methods require machine downtime during feeding, which is not only inefficient but also prone to unstable product quality due to manual errors.

[0003] In order to solve the above problems, we propose a forming and pressing device for magnetic core production. This forming and pressing device can automatically perform quantitative feeding after each pressing is completed, so as to carry out continuous processing and improve processing efficiency. Summary of the Invention

This forming and pressing device can automatically perform quantitative feeding after each pressing is completed, so as to carry out continuous processing and improve processing efficiency.

[0021] Example 1: A forming and pressing device for producing magnetic cores, such as Figure 1-Figure 7 As shown, it includes a frame 1, a collecting frame 2, a forming sleeve 3, a blanking plate 4, an electric push rod 5, a cylinder 6, an extrusion barrel 7, a quantitative component and a buffer component. The left part of the frame 1 is fixedly connected to the collecting frame 2, and the upper part of the frame 1 is fixedly connected to the forming sleeve 3. The left part of the collecting frame 2 is horizontally set, and the right part is inclined and located below the forming sleeve 3. The lower part of the forming sleeve 3 is slidably connected to the blanking plate 4, and the blanking plate 4 blocks the lower side of the forming sleeve 3. The upper part of the frame 1 is fixedly connected to the electric push rod 5, and the telescopic end of the electric push rod 5 is fixedly connected to the blanking plate 4. The upper side of the frame 1 is fixedly connected to the cylinder 6, and the telescopic end of the cylinder 6 is fixedly connected to the extrusion barrel 7 adapted to the forming sleeve 3. The extrusion barrel 7 is located directly above the forming sleeve 3. A quantitative component for automatically feeding quantitatively into the forming sleeve 3 is provided on the frame 1, and a buffer component for preventing the formed magnetic core from being impacted is provided on the left part of the collecting frame 2.

[0022] When using this device, a certain amount of magnetic powder is introduced into the molding sleeve 3 through the quantitative component, and the lower side of the molding sleeve 3 is blocked by the blanking plate 4, so that the magnetic powder stays in the molding sleeve 3, and then the extrusion cylinder 7 is controlled to move downward by the cylinder 6, and the extrusion cylinder 7 moves downward into the molding sleeve 3, and the magnetic core is pressed into shape by the cooperation of the extrusion cylinder 7 and the molding sleeve 3. After the pressing is completed, the extrusion cylinder 7 is controlled to move upward and reset by the cylinder 6. At the same time, the blanking plate 4 can be controlled to slide to the right and open by the electric push rod 5. The pressed magnetic core will fall from the lower side of the molding sleeve 3 into the collection frame 2, and under the action of the buffer component, the magnetic core sliding to the left along the inclined surface of the collection frame 2 will not directly collide with the side wall, avoiding damage to the magnetic core. After the magnetic core falls, the electric push rod 5 controls the blanking plate 4 to slide to the left and reset, and the quantitative component will automatically introduce a certain amount of magnetic powder into the molding sleeve 3, so as to carry out continuous processing and improve processing efficiency.

[0023] Example 2: Based on Example 1, Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the quantitative assembly includes a guide frame 8, a mounting frame 9, a first spring 10, a discharge barrel 11, a discharge pipe 12, a charging barrel 13, an electric guide rail 14, a fixed rod 15 and a top plate 16. The guide frame 8 is fixedly connected to the upper side of the frame 1, and the mounting frame 9 is slidably connected to the guide frame 8. A first spring 10 is connected between the mounting frame 9 and the guide frame 8 with a front-to-back symmetrical connection. The upper part of the mounting frame 9 is fixedly connected to the discharge barrel 11, and the lower part of the mounting frame 9 is fixedly connected to the discharge pipe 12. The upper right side of the discharge pipe 12 is connected to the lower part of the discharge barrel 11 through a branch pipe. The left side of the discharge pipe 12 is connected to the discharge barrel 11. The lower part is connected with a cover pipe, and the left end of the cover pipe is covered on the upper side of the forming sleeve 3. The branch pipe and the cover pipe are both inclined to facilitate the transportation of magnetic powder. A charging barrel 13 is slidably connected to the discharge pipe 12. Circular holes are provided on the upper right side and the lower left side of the charging barrel 13 for communication with the branch pipe and the cover pipe. An electric guide rail 14 is fixedly connected to the upper part of the discharge pipe 12, and the upper part of the charging barrel 13 is slidably connected to the electric guide rail 14. The left part of the mounting frame 9 is fixedly connected to a front-to-back symmetrical fixing rod 15, and the upper part of the extrusion cylinder 7 is fixedly connected to a front-to-back symmetrical top plate 16, which is squeezed and fitted with the adjacent fixing rod 15.

[0024] In the initial state, the top plate 16 presses against the fixed rod 15, the first spring 10 is in a deformed state, and the charging barrel 13 is in a state of communication with the cover tube. A certain amount of magnetic powder in the charging barrel 13 can enter the forming sleeve 3 through the cover tube. When the extrusion barrel 7 moves downward for pressing, the top plate 16 will also move downward with the extrusion barrel 7. After the top plate 16 moves downward, it no longer squeezes the fixed rod 15. At this time, under the action of the first spring 10 resetting, the mounting frame 9 slides to the right on the guide frame 8, and the mounting frame 9 slides to the right, driving the discharge barrel 11, the discharge pipe 12, the charging barrel 13, the electric guide rail 14 and the fixed rod 15 to move to the right. The charging barrel 13 moves to the right, driving the cover pipe to move to the right and misaligned with the forming sleeve 3, so that the extrusion barrel 7 enters the forming sleeve 3 for pressing. When the discharge pipe 12 moves to the right, the electric guide rail 14 can control the charging barrel 13 to slide upward, and the charging barrel 13 slides upward and is connected to the branch pipe. , the magnetic powder in the discharge barrel 11 can enter the charging barrel 13 through the branch pipe to fill the charging barrel 13. When the pressing is completed, the extrusion barrel 7 moves upward and resets. The extrusion barrel 7 moves upward and drives the top plate 16 to move upward. The top plate 16 moves upward and squeezes the fixed rod 15 to move to the left. The fixed rod 15 moves to the left and drives the mounting bracket 9 to slide to the left. The first spring 10 is deformed, and the mounting bracket 9 slides to the left, driving the discharge barrel 11, the discharge pipe 12, the charging barrel 13 and the electric guide rail 14 to move to the left. The charging barrel 13 moves to the right and drives the cover pipe to move to the left and cover the upper side of the molding sleeve 3 again. In the process of the discharge pipe 12 moving to the left, the electric guide rail 14 can control the charging barrel 13 to slide downward, so that the charging barrel 13 is connected to the cover pipe, and a certain amount of magnetic powder in the charging barrel 13 can enter the molding sleeve 3 through the cover pipe. In this way, a certain amount of magnetic powder can be automatically added to the molding sleeve 3 after completing one pressing.

[0025] like Figure 1 and Figure 7 As shown, the buffer assembly includes a buffer plate 17, a sliding rod 18 and a second spring 19. The left part of the collection frame 2 is slidingly connected with a front-to-back symmetrical sliding rod 18.

The buffer plate 17 is fixedly connected with the left side of the collection frame 2 with a front-to-back symmetrical second spring 19. The second spring 19 is sleeved on the adjacent sliding rod 18.

[0026] When using this device, the blanking plate 4 slides to the right and opens, and the pressed magnetic core will fall from the lower side of the forming sleeve 3 into the collection frame 2, and then slide to the left along the inclined surface of the collection frame 2. Under the action of the expansion and contraction of the second spring 19, the sliding rod 18 can drive the buffer plate 17 to move left and right, and the buffer plate 17 can buffer the magnetic core moving to the left, so as to avoid the magnetic core directly colliding with the side wall of the collection frame 2 and causing damage.
