Embodiment Construction

[0013] The AC demagnetization device for steel parts of the present invention will be further described in detail below through specific embodiments.

[0014] Such as figure 1 , figure 2 As shown, the AC demagnetization device for steel parts includes an outer frame 1 and an inner frame 2 arranged in the outer frame 1. The inner frame 2 divides the inner space of the outer frame 1 into a channel 3 with openings at both ends and an annular channel 4, The annular channel 4 is provided with a front end plate 5 and a rear end plate 6, and in the annular channel 4 between the front end plate 5 and the rear end plate 6, several layers of demagnetization coils 7 are wound in the circumferential direction. The front end plate 5 and the rear plate The end plate 6 is respectively provided with a ventilation window 8 and a spacer groove 9. The plurality of layers of demagnetization coils 7 are provided with spacers 10 at intervals, and a ventilation gap 11 is formed between the several laye...

Abstract

The invention relates to a steel part AC (alternating current) demagnetization device which comprises an outer frame and an inner frame arranged in the outer frame, wherein the inner frame divides the inner space of the outer frame into a channel with two end openings and an annular channel; the annular channel is internally provided with a front end plate and a rear end plate; the annular channel between the front end plate and the rear end plate is internally provided with a plurality of layers of degaussing coils in a winding manner along a circumferential direction; the front end plate and the rear end plate are respectively provided with a ventilating window and a spacing bar slot; and spacing bars are arranged at intervals among the layers of degaussing coils, and ventilating gaps are formed among the layers of degaussing coils. The steel part AC demagnetization device is suitable for demagnetizing steel parts.

Description

Technical field [0001] The invention relates to an AC demagnetization device for demagnetizing steel parts. Background technique [0002] Steel parts are magnetized during the production process from time to time. Magnetized workpieces are often not cleaned, which adversely affects the accuracy of subsequent processing. Therefore, demagnetization of steel parts before cleaning is a widely used process. [0003] The existing demagnetization devices include: single-phase AC demagnetizer with iron core, three-phase AC demagnetizer with iron core, DC demagnetizer with iron core, single-phase AC demagnetizer without iron core, DC demagnetization, AC Demagnetization device combined with demagnetization, rotating permanent magnet demagnetization device, etc. They can demagnetize most parts. They are insufficient for the demagnetization of parts requiring very low surface remanence. Summary of the invention [0004] The technical problem to be solved by the present invention is to prov...
