Description

Technical Field

[0001] The invention belongs to the technical field of magnetic core processing, and in particular relates to a magnetic powder automatic forming press for magnetic core processing and a forming method. Background Art

[0002] In modern science and technology and industry, magnetic cores, as an important component of electronic components, are widely used in electronic devices such as transformers, inductors, filters, etc. The main function of magnetic cores is to guide the magnetic field, enhance the electromagnetic induction effect, and improve the performance and efficiency of electronic equipment. Therefore, the processing quality and precision of the magnetic core have a crucial impact on the overall performance of the electronic device. Traditionally, the processing process of the magnetic core usually involves forming the magnetic powder into the desired shape and size through process steps such as pressing and sintering. When the existing equipment processes the magnetic powder into the magnetic core, the magnetic powder is loaded into the template through the cloth pushing structure, and the magnetic powder is compressed by the die head to form the magnetic core, and then the magnetic core is pushed out of the template by the blanking head, and then the magnetic core is pushed from the device to the blanking structure through the cloth backing result to complete the processing. In the above processing project, although the magnetic core can be processed, the template and the die head have a service life, and as the use time increases, the template and the die head will gradually wear out. Therefore, since the device has only one workstation, when the personnel need to replace the template, it is necessary to stop the machine, which will result in a long processing window period, reducing the processing efficiency of the device. In addition, the device collects the magnetic cores in a centralized manner and then manually collects the magnetic cores and places them on the sintering tray, which also increases the processing steps.

[0047] The compression part 3 includes a bottom mold part and a pressing mold part for extruding the bottom mold part, and, in the present invention, with respect to the above-mentioned bottom mold part, the bottom mold part includes a rotatable connecting frame 34, a base plate 37 is fixedly connected to the top of the connecting frame 34, the top of the base plate 37 is recessed in a circular array to form a plurality of slots 38, a pluggable template 313 is installed inside the slot 38, the template 313 is recessed to form a mold cavity 314, and limiting grooves 312 are formed on both sides of the base plate 37 near each slot 38, the limiting grooves 312 are connected to the slots 38, and the bottom plate of the template 313 is symmetrically fixedly connected with two limiting heads 311 matching the limiting grooves 312.

[0048] Through the above technical solution, when personnel need to process magnetic powder to form a magnetic core, the template 313 is placed in the slot 38 on the substrate 37, and the template 313 is rotated so that the template 313 drives the limit head 311 to rotate, so that the limit head 311 is engaged with the limit groove 312 on the substrate 37, thereby fixing the template 313, and then adding magnetic powder to the storage part of the feeding part 2, and conveying the magnetic powder to the mold cavity 314 on the template 313 through the conveying channel on the storage part, and the compression part 3 works, thereby driving the die part to move, and the die cavity 314 is squeezed by the die part. The magnetic powder in the mold is formed into a magnetic core, and the processing of the magnetic core is completed. When the personnel needs to replace the template 313, the template 313 is reversed so that the template 313 drives the limit head 311 to rotate, thereby separating the limit head 311 from the limit groove 312 on the substrate 37, and the template 313 can be taken out. Then, the unused template 313 is placed in the slot 38 on the substrate 37, and the template 313 is rotated so that the template 313 drives the limit head 311 to rotate, thereby engaging the limit head 311 with the limit groove 312 on the substrate 37, thereby completing the replacement of the template 313.

[0049] In addition, in the present invention, although the template 313 can be replaced, it still needs to be replaced manually. In order to improve the replacement efficiency of the template 313 and reduce the work risk of personnel when replacing the template 313, the molding press also includes a mold changing part 5, and the mold changing part 5 includes a storage unit 55 for storing the template 313.

The bottom of the fourth electric push rod 53 is fixedly connected to the suction cup 51, and the top of the suction cup 51 is fixedly connected to the vacuum pump 54.

[0050] In this embodiment, a plurality of templates 313 are placed on the storage unit 55 for storage, so that personnel do not need to directly contact the compression area on the device. After the template 313 is placed, the fourth electric push rod 53 drives the suction cup 51 to move downward, so that the suction cup 51 contacts the template 313 on the storage unit 55, and the vacuum pump 54 works to make the suction cup 51 absorb the template 313. The third motor 52 works to drive the fourth electric push rod 53 to rotate, so that the suction cup 51 rotates to the top of the slot 38 on the substrate 37, and the fourth electric push rod 54 drives the suction cup 51 to move downward, so that the suction cup 51 contacts the template 313 on the storage unit 55. 3 works, thereby driving the suction cup 51 to move downward, and the template 313 is driven downward by the suction cup 51 until the template 313 is inserted into the slot 38 on the base plate 37, and the third motor 52 works, thereby driving the suction cup 51 and the template 313 to rotate, so that the limiting head 311 on the template 313 is engaged with the limiting groove 312 on the base plate 37, the vacuum pump 54 stops working, and the fourth electric push rod 53 moves back to separate the suction cup 51 from the template 313, so that personnel do not need to manually replace the template 313, thereby improving the replacement efficiency of the template 313.

[0051] Furthermore, in the present invention, in order to allow the device to automatically replenish the template 313 and store it, it is convenient to replace the template 313 later, such as Figure 11-13 As shown, the following implementation modes are provided:

[0052] Implementation Method 1

[0053] The material storage unit 55 includes two symmetrically arranged base frames 551, and the opposite sides of the two base frames 551 are rotatably connected to multiple connecting rods 557, and the opposite sides of the two base frames 551 are fixedly connected to multiple limiting rods 554, the limiting rods 554 are matched one by one with the limiting plates 556, and the limiting rods 554 are above the limiting plates 556, and each connecting rod 557 is sleeved with a limiting plate 556.

[0054] In this embodiment, when personnel need to store the template 313 in the two base frames 551, the template 313 to be stored is placed above the loading plate 56, and the loading plate 56 is driven to move by the fifth electric push rod 57, and the template 313 is driven to move upward by the loading plate 56. When the template 313 contacts the limit plate 556, the limit plate 556 is pushed by the template 313 to rotate upward, and then the limit plate 556 is tilted until the template 313 moves to the previous limit plate 556. According to the above steps, the template 313 is pressed onto each limit plate 556, thereby completing the replenishment of the template 313.

[0055] Implementation Method 2

[0056] The material storage unit 55 includes two symmetrically arranged base frames 551, and a first card slot 552 and a second card slot 553 are provided on symmetrical sides of the two base frames 551.

A limiting plate 556 is sleeved on each connecting rod 557, and both ends of the connecting rods 557 are screwed together with a second screw ring 558 for resisting the base frame 551.

[0057] In this embodiment, when the personnel need to store the template 313 in front of the two base frames 551, they take the number of limit plates 556 required by the personnel, place the limit plates 556 on the base frames 551, engage the connecting rod 557 on the limit plates 556 with the first slot 552 on the base frames 551, and then engage the limit rod 554 with the second slot 553 on the base frames 551, and screw the second screw ring 558 with the connecting rod 557, so that the two adjacent limit plates 556 are adjusted to the distance required by the personnel, and screw the first screw ring 555 with the limit rod 554 to make the adjacent The limiting rod 554 is adjusted to the distance required by the personnel, and the template 313 to be stored is placed above the loading plate 56. The loading plate 56 is driven to move by the fifth electric push rod 57, and the loading plate 56 is used to drive the template 313 to move upward. When the template 313 contacts the limiting plate 556, the limiting plate 556 is pushed by the template 313 to rotate upward, and then the limiting plate 556 is tilted until the template 313 moves to the previous limiting plate 556. According to the above steps, the template 313 is pressed onto each limiting plate 556, thereby completing the replenishment of the template 313.

[0058] Furthermore, when the base frame 551 receives the template 313, in order to allow the template 313 to be received by the base frame 551 more quickly, in the present invention, Fig.11 As shown, the mold changing component 5 also includes a second support frame 58, which is located on one side of the material storage unit 55, and the top of the second support frame 58 is symmetrically rotatably connected to two second transmission rollers 510, and a second conveyor belt 511 is rotatably connected between the two second transmission rollers 510, and a fourth motor 59 is fixedly connected to the second support frame 58, and the output end of the fourth motor 59 is connected to the second transmission roller 510.

[0059] In this embodiment, when personnel need to store the templates 313 between the two base frames 551, multiple templates 313 are placed on the second conveyor belt 511, and the fourth motor 59 is operated to drive the second transmission roller 510 to rotate, and the second transmission roller 510 drives the second conveyor belt 511 to rotate, and the second conveyor belt 511 drives the templates 313 to move one by one to the loading plate 56, so that the templates 313 can be easily loaded between the two base frames 551.

[0061] In this embodiment, when the template 313 needs to be replaced, the first motor 35 is operated, so that the first motor 35 drives the connecting frame 34 to rotate, and then drives the base plate 37 to rotate, so that the position of the template 313 is easy to rotate, and the template 313 is easy to replace. When the magnetic powder is processed into a magnetic core, the third electric push rod 36 is operated to drive the base frame 310 to move, and the base frame 310 drives the push head 39 to move, and the push head 39 pushes the magnetic core in the mold cavity 314, so that the magnetic core moves to the outside of the mold cavity 314, so that the magnetic core is easy to collect.
