Abstract

The invention discloses a progressive orientation mold for multi-pole magnetic rings and an orientation method thereof, which solves the technical problems that the products prepared by the orientation mold and the orientation method in the prior art have large upper and lower extreme differences and differences in surface magnetism. It includes a mold core (1) and a mold sleeve (2) arranged outside the mold core (1), and there is an annular gap between the mold core (1) and the mold sleeve (2); the mold core (1) and the mold At least one of the sleeves (2) is provided with a cavity inside, and a movable orienter (5) is provided in the cavity, and the orienter (5) is connected to the controller; the upper end of the annular gap is provided with a size The matching upper pressing head (3), the lower end of the annular gap is provided with the matching lower pressing head (4). The invention is used in the preparation of the multi-pole magnetic ring, can effectively reduce the upper and lower pole difference of the multi-pole magnetic ring, and improve the working performance of the multi-pole magnetic ring.

Description

Technical field [0001] The present invention relates to an orientation mold of a multipolar magnetic ring and an orientation method thereof, specifically to a multipolar magnetic ring progressive orientation mold and an orientation method thereof. Background [0002] Multi-pole magnetic ring is widely used in stepper motors, instrumentation, sensors, timers and other new generation products, especially multi-pole magnetic ring permanent magnet motors, under the same torque, power and other performance indicators, compared with other similar motors (such as electroexcitation motors, bonded permanent magnet multi-pole rotor motors) more simple structure, small size, good stability and other advantages. [0003] Orientation molding process is the core process of producing anisotropic multipolar magnetic ring, the current general steps are: mold sleeve and lower indenter downward, the mold core remains unchanged, the three form a preset cavity volume, the packing box is moved back a...
