Problems solved by technology

The demagnetization work efficiency and demagnetization standards required in the manufacturing process and the regular maintenance process after use are getting higher and higher. Relying on simple equipment for demagnetization can no longer meet the needs of rapid development.
[0003] The current demagnetization equipment basically uses a single magnetic field, single power, fixed working intensity, fixed working height, and fixed transmission speed for demagnetization, which cannot guarantee fast and efficient demagnetization of existing workpieces. There is no reliable and effective equipment and method for one-time overall demagnetization of "ultra" workpieces, and poor demagnetization quality will directly affect the service life and safety of the workpiece
In addition, in the past, to demagnetize large workpieces, a hand-held demagnetizer was used to move the demagnetization along the surface. On the one hand, this kind of local demagnetization will greatly increase the labor intensity, waste manpower and reduce work efficiency; Demagnetization at one place, overflow at another place, re-magnetization phenomenon

Abstract

The invention relates to workpiece demagnetizing equipment, in particular to a tunnel scanning pass-type demagnetizer. The tunnel scanning pass-type demagnetizer comprises a bed body and a control cabinet; the bed body comprises a base and a material loading bridge frame, wherein the material loading bridge frame is positioned above the base and is connected with the base end to end; a sports car is arranged on the base; the base is movably connected with the sports car; the upper part of the sports car is connected with an executive coil by adopting a supporting screw; and the sports car is also provided with a variable frequency motor. By the adoption of the tunnel scanning pass-type demagnetizer, the labor intensity of workers is lightened; the running speed of the sports car, the demagnetizing intensity and the waveform can all be adjusted; safe and efficient demagnetization can be realized; the quality of a workpiece is improved; and therefore, the service life of the workpiece is prolonged.

Description

technical field [0001] The invention relates to a device for degaussing workpieces, in particular to a tunnel scanning and passing demagnetizing machine. Background technique [0002] Since the metal has a certain magnetic content after machining, the magnetic content of the workpiece varies according to the processing technology, which greatly affects the quality of the workpiece. Therefore, a large number of workpieces are applied to industries such as industry and transportation. need to be demagnetized. The demagnetization work efficiency and demagnetization standards required in the manufacturing process and the regular maintenance process after use are getting higher and higher. Relying on simple equipment for demagnetization can no longer meet the needs of rapid development. [0003] The current demagnetization equipment basically uses a single magnetic field, single power, fixed working intensity, fixed working height, and fixed transmission speed for demagnetizatio...
