Embodiment 1

[0014] 1) Bonding step: first use 502 glue to bond the cut glass backing plate to the clean and dry material plate, and at the same time use glue to bond the strips together on the bonding tooling, and then glue the bonded glass The material board is placed on the positioning tool, and finally the bonded strips are bonded on the material board according to the reference positioning.

[0015] 2) Loading step: After the bonding is completed, use a forklift to transfer the bonded whole sheet to the storage rack, and then use a forklift to send the entire sheet to the workbench of the multi-wire cutting equipment. Cut according to the corresponding scheme of the material specification.

[0016] 3) Cutting steps: confirm the cutting zero point, set the cutting parameters, start the cutting program, and then perform arc cutting, line withdrawal and unloading in sequence after the cutting is completed. The cutting parameters are set as:

[0017] Pay-off tension: 10N; take-up tension...

Abstract

The invention discloses a NdFeB permanent magnetic material processing method which includes the step of material binding and the step of cutting. In the step of material binding, a material plate is attached to a smooth and flat cushion plate in an adhesive mode through an adhesive, bar-shaped materials to be processed are attached together through the adhesive, the attached bar-shaped materials to be processed are positioned and attached to the material plate for processing, and the adhesive can not permeate the cushion plate; in the step of cutting, a cutting zero point is determined, cutting parameters are set, arc cutting, wire retracting and unloading are sequentially finished after cutting through a multi-wire sawing machine, and the cutting parameters are set in the mode that unwinding tension is 10-40 N, winding tension is 10-40 N, cutting speed is 10-500 mm / s, reciprocating time is 10-60 S, arc suppression time is 500-2000 S, and new wire feeding speed is 20-40 m / min.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a processing method of NdFeB permanent magnet materials and special equipment thereof. The method can achieve the effects of improving cutting efficiency and ensuring cutting precision. Background technique [0002] Multi-wire cutting machine is widely used in the cutting and processing fields of monocrystalline silicon and sapphire, and is a processing equipment with high cutting precision. It is the first time that our company has introduced it to the processing field of NdFeB permanent magnet materials on a large scale. [0003] The working principle of the multi-wire cutting machine is to grind and cut monocrystalline silicon, sapphire and other materials on the high-speed reciprocating thin steel wire by pouring emery or silicon carbide mortar. [0004] The currently known NdFeB processing method is to use a fully automatic internal circle slicer or a single-wire EDM cutt...
