Grinding Technology of Cast AlNiCo Magnetic Steel

Abstract

The invention relates to a grinding process technology for casting aluminum-nickel-cobalt magnetic steel, and belongs to the technical field of metal processing. According to the technology, raw materials are mixed and uniformly stirred, the magnetic steel is molded by melting and pouring by adopting an intermediate frequency furnace, the outer circumference of the magnetic steel is ground and processed by adopting an outer circumferential clamping claw assembly. The magnetic steel is placed on a feeding disc in a feeding disc feeding assembly after outer circumferential processing is completed, and grinding processing is conducted on the two end faces of the magnetic steel by grinding wheels arranged at the two ends of the feeding disc. A left grinding wheel telescopic oil cylinder and a right grinding wheel telescopic oil cylinder retract after grinding processing on the two end faces of the magnetic steel performed by a double-end-face grinding machine, a motor is driven by a material disc to drive the material disc to leave along a feeding track from a feeding base, the magnetic steel on which grinding processing is completed is taken out after the material disc is moved back a designated position, and new to-be-processed magnetic steel is replaced to perform cycling operation. The technology has the advantages that the product quality stability is good, the grinding amount is low, the processing efficiency is high, the operation is convenient and fast, the service life of the grinding wheel is long, the grinding processing technology of the magnetic steel is simplified, and the grinding efficiency and product dimension precision are improved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a casting AlNiCo magnetic steel grinding process. Background technique [0002] Magnetic steel generally refers to AlNiCo alloy. Magnetic steel is composed of several hard and strong metals, such as iron and aluminum, nickel, cobalt, etc., sometimes copper, niobium, and tantalum. It is used to make superhard permanent magnetic alloys. The composition of its metal components is different, its magnetic properties are different, and its uses are also different. It is mainly used in various sensors, instruments, electronics, electromechanical, medical, teaching, automotive, aviation, military technology and other fields. Alnico magnet is the oldest kind of magnet, known as natural magnet. Although it is the oldest, its excellent adaptability to high temperature makes it still one of the most important magnets. Alnico can work normally at a high temperature above 500°C, whic...
