Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic block production equipment, in particular to a magnetic block processing and forming equipment and method. BACKGROUND

[0002] Magnetic blocks are widely used in various industries. The currently used magnetic blocks are divided into natural magnetic blocks and artificial magnetic blocks. The magnetic force of artificial magnetic blocks is controllable during production, and different types of products can be prepared, which are widely used. The manufacturing process is to select ferromagnetic metals, crush them, and then transfer them to a pressing and forming equipment for pressing and forming. The alloy block is sintered in a sintering equipment, and finally the magnetic block is formed after being magnetized by a magnetizing machine. The forming mainly relies on hydraulic forming. For example, a Chinese utility model patent with the publication number CN210523816U discloses a device for pressing and forming magnetic material, which comprises a device box. The device box is internally provided with a hydraulic device fixed on both sides of the bottom. The hydraulic device is provided with a hydraulic rod penetrating through the top surface of the device box. The four hydraulic rods are fixed with a fixed plate on the top. The fixed plate is provided with an upper pressing block on the bottom surface. The lower pressing block is arranged below the upper pressing block. A push motor is fixed on the inner bottom surface of the device box. The push motor is provided with an extension push rod. The extension push rod is fixed with a push platform above. However, the current artificial magnetic block has the following defects during forming:

[0003] The current artificial magnetic block production process needs to transfer the product multiple times, resulting in loss. The highest loss rate occurs in the forming process. After hydraulic forming, the alloy block needs to be taken out and sent to the sintering equipment for sintering and forming. The alloy block after hydraulic forming is very fragile and is prone to edge loss and fragmentation during transfer, resulting in loss and the need to return for reprocessing, which increases the production cost.
