Material bonding device and machining method of neodymium iron boron tile-shaped magnet

Abstract

The invention discloses a material bonding device and a machining method of a neodymium iron boron tile-shaped magnet. The material bonding device comprises a material bonding tool which is in a flat plate shape, wherein two parallel convex edge sliding rails are arranged on the upper surface of the material bonding tool, two vertical rods which are perpendicular to the material bonding tool and extend upwards are arranged on the two side walls of the material bonding tool, and the top ends of the two vertical rods are fixedly connected with a material bonding tool stop lever; and a material plate platform, wherein the longitudinal section of the material plate platform is in an L shape, grooves matched with the convex edge sliding rails are formed in the lower surface of the material plate platform, the grooves and the convex edge sliding rails are connected in an inserted mode, a material plate is detachably installed on the material plate platform, and the material bonding tool stop lever is higher than the material plate. According to the machining method of the neodymium-iron-boron tile-shaped magnet based on the material bonding device, secondary cutting is conducted on a neodymium-iron-boron magnet blank by means of a tile-shaped multi-wire cutting machine, and finally the neodymium-iron-boron tile-shaped magnet with the inner arc radius and the outer arc radius being different are obtained. According to the method, the machining qualification rate can be increased, and the machining efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of magnet processing. More specifically, the present invention relates to a material bonding device and a processing method for NdFeB tile magnets. Background technique [0002] Multi-wire cutting is a new type of cutting process that brings the abrasive into the blank processing area for grinding through the high-speed reciprocating motion of the metal wire, and cuts the blank into hundreds of thin slices at one time. It has high production efficiency, less loss, The surface damage layer of the product is small and the roughness is small. As a new cutting technology with a new concept, it has been applied to the batch cutting of magnetic steel products. Because of its excellent magnetic properties, NdFeB magnets are widely used in electronics, medical equipment, aerospace and other fields, such as tile-shaped magnets used in permanent magnet motors. However, NdFeB magnets contain precious rare earth eleme...

Problems solved by technology

However, with this processing method, due to the different radii of the inner and outer arcs, the total grinding amount of the arc surface is large, and the processing efficiency is low.

Although the application of multi-wire cutting technology in the NdFeB industry is currently in a stage of rapid development, many processes and tooling technologies still need to be optimized. Move the square to stick the blanks on the fabric board and arrange them in M ​​rows*N columns. The efficiency is low, and the horizontal and vertical spacing of the blanks is difficult to control, which will affect the precise processing of multi-wire cutting, eventually waste materials, and easily cause equipment disconnection
