Magnetostatic field magnetizing device and method at normal temperature

Abstract

The invention belongs to the technical field of magnetizing, and aims to provide a magnetostatic field magnetizing device and method at a normal temperature. The device is compact in structure, stable in performance, safe and reliable, capable of saving energy and high in magnetizing efficiency. The device comprises an upper magnetizing source device and a lower magnetizing source device. The upper magnetizing source device comprises an upper supporting plate, yoke iron bodies and magnetizing magnetic steel bodies. Each yoke iron body is in the shape of a cuboid, and the four side faces of each yoke iron body are each provided with one magnetizing magnetic steel body in a pasting mode. The lower ends of the yoke iron bodies protrude out of the magnetizing magnetic steel bodies, and magnetizing heads are pasted in the central positions of the yoke iron bodies. The bottoms of the magnetizing magnetic steel bodies are fixedly attached to the upper supporting plate. A through groove is formed in the central position of the upper supporting plate, and the magnetizing heads of the yoke iron bodies are located in the through groove of the upper supporting plate. The structure of the lower magnetizing source device is the same as the structure of the upper magnetizing source device, and the lower magnetizing source device and the upper magnetizing source device are symmetrically arranged. A material guide plate is arranged between a lower supporting plate of the lower magnetizing source device and the upper supporting plate of the upper magnetizing source device, material guide through grooves are formed in the material guide plate, and the positions of the material guide through grooves correspond to those of the magnetizing heads. The lower supporting plate is fixedly connected with the upper supporting plate.

Problems solved by technology

This type of equipment mainly has the following disadvantages: 1. The traditional magnetization equipment has large energy consumption and low efficiency; 2. The traditional magnetization equipment mainly uses pulse magnetization, the control system is simple, there is no protection device, and most of them are manually controlled. ; 3. The traditional magnetizing equipment uses hollow coils. The high current passing through the magnetizing process will generate high heat, which is not suitable for long-term and frequent use. If cooling equipment is added, more energy consumption will be increased; 4. Traditional magnetizing equipment Occupying a large area and high instantaneous current present potential safety hazards

[0004] Patent No. 201310535597.5 discloses a static magnetic field magnetization device and magnetization method. Its disadvantages are high temperature magnetization, high energy consumption, long magnetization time and low efficiency, which affects its promotion.
