Embodiment Construction

[0021] The following examples are further explanations and descriptions of the present invention, and do not constitute any limitation to the present invention.

[0022] Refer to figure 1 , The method for grabbing and moving the compacted low-density magnet blank of the present invention includes the following steps:

[0023] S10: Low-density magnet blank pressing

[0024] Such as figure 1 As shown, a low-density magnet blank 20 is molded by a press 10. In this step, the press 10 may be a suitable known magnet pressing equipment, which presses a magnet device such as a magnetic ring through a mold. The low-density magnet is a magnet that is loose and fragile and easy to be reduced to magnetic powder in the subsequent magnetic field orientation compression molding, and has the same weight and the same size as the magnet that is magnetic field orientation compression molding. In this embodiment, the press 10 molds the low-density magnet blank 20 under a relatively small pressure. Afte...

Abstract

The invention provides a pressed low-density magnet blank grabbing and moving method and device. The method comprises the steps that a, mould pressing is conducted by a pressing machine to obtain a low-density magnet blank; b, a vacuum clamping sleeve for fixing the magnet blank is clamped by a mechanical arm with a negative pressure device, and the vacuum clamping sleeve is moved to the upper side of the magnet blank on the pressing machine from the exterior of the pressing machine; c, the magnet blank is clamped by the mechanical arm through the vacuum clamping sleeve; d, the mechanical armmakes the clamped vacuum clamping sleeve and the magnet blank move to a magnet blank placement table, pressure is released, and the magnet blank is released, so that the process of grabbing the magnetblank one time is completed. The device comprises the mechanical arm and the vacuum clamping sleeve, the mechanical arm is provided with or connected with the negative pressure device, the vacuum clamping sleeve is a sleeve body in a shape identical to that of the magnet blank, and the diameter of the vacuum clamping sleeve is larger than the diameters of upper and lower openings of the magnet blank. By means of the device, the low-density magnet blank can be grabbed and moved, in the grabbing and moving processes, the magnet blank cannot be collided or squeezed, and it can be ensured that the magnet blank is moved to another point from one point without damage.

Description

【Technical Field】 [0001] The invention relates to a press-formed magnet, in particular to a method and device for grabbing and moving a press-formed low-density magnet blank that is loose, fragile and easy to reduce to magnetic powder. 【Background technique】 [0002] In the magnet compression molding process, in order to ensure that the weight of the added magnetic powder is accurate when the magnet is pressed, and to overcome the problem that the powder cannot be added uniformly and accurately due to other process conditions, it is necessary to place the magnetic powder in a non-magnetic field. Under the conditions, the magnet blanks of equal weight and size are first pressed in the mold. In order to ensure that the magnetic powder can be fully oriented under the action of the orientation magnetic field, it is necessary to make the magnet on the basis of molding, try to reduce the density, make the magnet loose and fragile, so that the magnet can be placed in a mold with a curvi...
