Embodiment Construction

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

[0022] refer to figure 1 , the gripping and moving method of the low-density magnet blank of press molding of the present invention comprises the following steps:

[0023] S10: Low-density magnet blank pressing

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

Abstract

A method and device for grabbing and moving low-density magnet blanks formed by pressing, the method comprising: a. molding a low-density magnet blank by a press; Jacket, the vacuum jacket is moved from the outside of the press to the top of the magnet blank on the press; c, the manipulator clamps the magnet blank through the vacuum jacket; d, the manipulator moves the clamped vacuum jacket and the magnet blank to The magnet blank is placed on the table, the pressure is relieved and released, and the magnet blank is grasped once. The device includes a manipulator and a vacuum jacket. The manipulator is equipped with or connected with a negative pressure device. The vacuum jacket is a sleeve-like body with the same shape as the magnet blank and a diameter larger than the upper and lower openings of the magnet blank. The invention can grasp and move the low-density magnet blank, without collision and extrusion to the magnet blank during the grasping and moving process, and can ensure that the magnet blank is moved from one point to another intact.

Description

【Technical field】 [0001] The invention relates to a press-formed magnet, in particular to a grasping and moving method and device for a press-formed loose and fragile low-density magnet blank that is easily reduced to magnetic powder. 【Background technique】 [0002] In the compression molding process of magnets, in order to ensure that the weight of the added magnetic powder is accurate during the compression molding of the magnet, 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 the absence of a magnetic field. Under certain conditions, 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, the density of the magnet must be reduced as much as possible on the basis of molding. , can be broken instantly, reduced to magnetic powde...
