Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component...

The invention relates to a magnetic field forming press for a neodymium-iron-boron magnet and a using method of the magnetic field forming press. The magnetic field forming press comprises a first working panel, a lower pressing block, a working hydraulic cylinder, an upper pressing block and a telescopic base mechanism, wherein the first working panel is arranged on supporting legs, and a channelused for pressure forming is formed in the center of the first working panel; the lower pressing block is arranged below the first working panel and corresponds to the channel of the first working panel; a liquid channel penetrating through the upper surface and the lower surface is formed in the lower pressing block, and a first pushing block and a second pushing block are arranged at the two ends of the liquid channel correspondingly; the working hydraulic cylinder is arranged above the first working panel, and the other end of the working hydraulic cylinder is connected to a second workingpanel; the upper pressing block is arranged in the center of the lower surface of the second working panel, the upper pressing block shrinks in a stepped mode, and the front end of the upper pressingblock is matched with the channel of the first working panel; and the telescopic base mechanism is hinged to the lower pressing block. After die casting is completed, the die-cast magnet in a die canbe directly taken out, manual operation is avoided, the working efficiency is improved, and the labor cost is saved.
Description
technical field [0001] The invention relates to the field of NdFeB magnet production equipment, in particular to a magnetic field forming press for NdFeB magnets and a method for using the magnetic field forming press. Background technique [0002] NdFeB magnetic material is a tetragonal crystal formed by neodymium, iron and boron, and is widely used in the preparation of NdFeB magnets. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. [0003] Die-casting is often required after crushing. General die-casting devices often use molds. After the die-casting is completed, tools are required to remove the magnets in the mold, which affects production efficiency and has high labor costs. Contents of the invention [0004] Based on this, it is necessary to address the above problems and provide a magnetic field forming press for NdFeB magnets, which can perform die-casting of NdFeB magnets, and has th...
