Problems solved by technology

[0004] However, the chamfering machine in the above-mentioned patent uses cutting to chamfer, and a large amount of burrs and debris will be generated after chamfering, which not only wastes raw materials, but also increases the post-polishing process, and needs to be carried out many times for stepped corners. Chamfering, chamfering takes a long time, and the existing chamfering machine can only chamfer a single-shaped NdFeB magnet. For irregular-shaped NdFeB magnets, multiple chamfering machines are required. Corner, the required chamfering processing time is long, and the processing efficiency is low

Abstract

The invention discloses a multi-directional automatic chamfering machine for NdFeB magnet processing and its implementation method, which belongs to the technical field of chamfering machines, and includes a support frame, a rocker device, a chamfering device and a clamping device. The support frame Clamping devices and chamfering devices are respectively connected to the inner walls on both sides of the rocker device; the support frame includes a U-shaped frame body and a lifting assembly, and the side walls on both sides of the U-shaped frame body are fixed and connected by bolts. There is a lifting assembly; the rocker device includes a rotating motor and a rocker rod body, and the motor shaft of the rotating motor is connected to the rocker rod body through a coupling. Chamfering is performed by roller extrusion, which reduces the formation of burrs, saves raw materials, and improves the compactness of the chamfering; it can perform one-time chamfering on stepped corners, which improves processing efficiency and saves processing time; Tubular, plate and block NdFeB magnets are chamfered.

Description

technical field [0001] The invention relates to the technical field of chamfering machines, in particular to a multi-directional automatic chamfering machine for NdFeB magnet processing and its implementation method. Background technique [0002] NdFeB magnets can be divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonding is actually injection molding, while sintering is vacuum forming by high temperature heating. NdFeB magnets are the permanent magnets with the strongest magnetic force at room temperature so far (the magnetism is second only to holmium magnets at absolute zero, but the magnetism at room temperature is far stronger than all currently known permanent magnets). Material grades are N35-N52; various shapes can be processed according to specific requirements: round, square, perforated, magnetic tile, magnetic rod, convex, trapezoidal, etc.; mainly used in electronics, electrical appliances, packaging, motors, toys, leather goods , Automobile machi...
