Problems solved by technology

However, the pressing efficiency is not high when using this type of press to produce radiation-oriented magnetic rings, and products of different specifications need to be equipped with electromagnets of different specifications, which limits the ability of enterprises to use this type of press to produce radiation-oriented magnetic rings of different specifications
In addition, due to the high price of this type of press, it is impossible for small-scale magnetic material manufacturers to purchase a large number of special presses and electromagnets for radiation-oriented magnetic rings of different specifications to achieve large-scale production

Embodiment Construction

[0008] to combine figure 1 figure 2 , adopt common four-cylinder press as the molding production equipment of radiation orientation magnetic ring, but install magnetic guide plate 7,21 additionally between press frame 3, and the surrounding of the molding die of magnetic ring is made of magnetic guide material. During the specific operation, first remove the upper cover plate 15 of the mold, open the appropriate distance between the left and right press heads 16, 14 of the press, pour the weighed powder into the mold cavity 19, cover the upper cover plate 15, and put the entire mold Manually push to the fixed position of the press, controlled by the automatic control device (PLC machine) of the press, the lower cylinder 13 drives the lower pole 11 to go down to the end, the backing plate 9 restricts the mold from going down, under the action of the upper cylinder 1 and its own weight, the upper pole The column 4 goes down and is pressed against the upper cover plate of the m...

Abstract

This invention discloses one radiating magnetic ring shaping process, which adopts regular four cylinders as processing device and locates magnetic guide board between frames. The shaping mode four sides are made by magnetic conductive materials with direct different current with the process machine. The magnetic ring is put in static machine under certain pressure for a while and is opened and sent to the sintering furnace. The invention is free of special radiating magnetic ring machine and in regular machine for batch production. The shaping materials adopt mode voltage with high shaping intensity.

Description

technical field [0001] The invention relates to a manufacturing process of a magnetic material, in particular to a forming and manufacturing process of a radiation-oriented magnetic ring. Background technique [0002] At present, ordinary four-cylinder presses are generally used as pressing equipment for the forming and production of ordinary vertically oriented hard magnetic materials. During the specific operation, it is necessary to make a mold made of non-magnetic material around it according to the shape requirements of the magnetic material, so as to facilitate the consistency of magnetization and reduce magnetic loss. Then remove the upper cover plate of the mold, open the left and right pressure heads of the mold at an appropriate distance, pour the weighed powder into the cavity, cover the upper cover plate, and manually push the whole set of molds to the fixed position of the press. Controlled by the automatic control device of the press, under the action of the u...
