Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic core processing equipment, in particular to a powder forming press for magnetic cores. Background Art
[0002] A powder forming press for magnetic cores is a machine specifically designed for compacting magnetic material powders. It is primarily used to produce magnetic core components for electronic components such as inductors and transformers. This press automatically feeds magnetic powder material into a die through a hopper, feed tube, and shoe. A punch then applies pressure to the powder, shaping it into a magnetic core of the desired shape and size. Magnetic materials include manganese-zinc ferrite, nickel-zinc ferrite, neodymium-iron-boron, aluminum-iron-boron, iron-silicon, and sendust. These cores are widely used in a variety of fields, including electronics, power generation, communications, and automotive.
[0003] In the existing powder forming press for magnetic cores, loading and unloading of materials are usually performed manually on the model base below the upper mold of the press. During the manual loading and unloading process, the operator needs to have close contact with the upper mold of the press, which is prone to accidental injuries. In addition, the accuracy of manual loading and unloading is difficult to guarantee, which may lead to unstable size and shape of the product and affect product performance. In addition, the single stamping structure of this press wastes time through manual loading and unloading, resulting in reduced processing efficiency.
[0004] Therefore, it is necessary to invent a powder forming press for magnetic cores to solve the above problems. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] The utility model provides Figure 1-5 The shown magnetic core powder molding press includes a base 1, which serves as the supporting structure of the entire device. The base 1 is of a stable and sturdy design, which can ensure that the device remains stable during operation and avoid product quality problems caused by vibration or displacement. A mold base 2 is provided above the base 1. The mold base 2 is used to carry and fix the mold. Its design must be adapted to the position and size of the upper mold 32 to ensure that the mold remains stable during the pressing process. A hopper 5 is provided above both ends of the base 1. A powder box 7 is placed above the base 1 and below the mold base 2. The powder box 7 is used to collect excess magnetic powder material in the mold hole 22 of the mold base 2 to avoid material waste.
[0025] A discharge port 51 is provided at the bottom of the hopper 5, which is used to store and transport magnetic powder material. This ensures that the powder material flows smoothly into the female mold, while the design of the partition 53 helps control the flow of powder material to avoid excessive or insufficient powder material. The bottom of the discharge port 51 contacts the upper surface of the mold base 2. Both the bottom of the discharge port 51 and the upper surface of the mold base 2 are smooth surfaces. A slot 52 is provided on the front of the discharge port 51, extending through the interior of the discharge port 51. A partition 53 is inserted into the slot 52. The partition 53 has an L-shaped structure, and the tail end of the partition 53 contacts the lower end of the mold base 2.
[0026] Furthermore, in the above technical solution, slide grooves 11 are provided on both sides of the upper part of the base 1, and sliders 21 are fixedly installed on both ends of the bottom of the model base 2. The bottom of the model base 2 is slidably connected to the slide grooves 11 on both sides of the upper part of the base 1 through the sliders 21, which is convenient for the operator to adjust and move the model base 2.
[0027] Furthermore, in the above technical solution, limit bars 4 are provided at both ends of the upper side of the base 1, and both ends of the limit bars 4 are fixedly connected to the base 1 by bolts. The powder box 7 is located between the two limit bars 4, and the model base 2 is located between the two limit bars 4. The limit bars 4 are used to limit the up and down movement range of the model base 2 to ensure that during the back and forth movement of the model base 2, no matter which model hole 22 can be accurately located below the upper mold 32.
[0028] Furthermore, in the above technical solution, a press 3 is provided in the middle part of the base 1, a stamping mechanism 31 is provided on the top of the press 3, an upper mold 32 is fixedly installed at the bottom center of the stamping mechanism 31, and both sides of the press 3 are fixedly installed above the base 1 through stands. The model base 2 is located between the two stands. The stands are used to support and fix the model base 2 to ensure its stability during operation. The stamping mechanism 31 applies pressure to the powder material in the model hole 22 to form it into a magnetic core of the required shape and size.
[0029] Furthermore, in the above technical solution, model holes 22 are provided at both ends of the upper portion of the model base 2, and the positions of the model holes 22 are adapted to the position and size of the upper mold 32. Handles 23 are fixedly installed at both ends of the model base 2, and the handles 23 facilitate the operator to move and adjust the model base 2.
[0030] Furthermore, in the above technical solution, support rods 6 are vertically fixedly installed at both ends of the hopper 5. The support rods 6 on both sides of the same hopper 5 are respectively located on both sides of the base 1. The installation position of the support rods 6 is fixed. The support rods 6 are used to stably support the hopper 5 so that the hopper 5 is maintained at an appropriate position height.
[0031] The working process of the powder forming press for magnetic cores provided by the utility model is as follows:
[0032] Ensure that the power supply of the powder molding press for the magnetic core is turned on and that the power supply voltage meets the equipment requirements. Pour the magnetic powder material into the hopper 5. The type and quantity of the powder should be adjusted according to production requirements. Check whether the model hole 22 on the model base 2 matches the position and size of the upper mold 32. Confirm that the stamping mechanism 31 of the press 3 has been correctly installed on the upper mold 32.
[0033] Pull the handle 23 at one end of the model base 2, and then the model base 2 moves in the pulling direction. When the model base 2 moves to this direction, the end of the model base 2 touches the tail end of the partition 53, and then the partition 53 moves from the inside of the slot 52 to the outside. When the bottom of the end of the model base 2 contacts the limit bar 4 at this end, it stops moving, and the partition 53 at the bottom of the hopper 5 is fully opened. The magnetic powder material in the hopper 5 falls into the model hole 22 at this end of the model base 2. When the material in the model hole 22 at this end is filled, the model is pushed in the opposite direction by the handle 23. The base 2 is pushed upwards and the partition 53 at this end is pushed in the opposite direction to close the discharge port 51 at the bottom of the hopper 5, and the model hole 22 filled with material is pushed to the bottom of the upper mold 32 of the press 3. At this time, the other end of the model base 2 conflicts with the limit bar 4 at the other end of the base 1, and then the press 3 presses the model hole 22 filled with material to press the magnetic core. During the process of pressing the magnetic core, the staff moves to the other end, or the staff at the other end loads or unloads the model hole 22 at the other end of the model base 2, and repeats the above process to quickly realize the processing of the magnetic core.
[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
