Description

A kind of amorphous soft magnetic alloy magnetic core up-coiler
1, technical field
The present invention relates to a kind of winding apparatus, particularly relate to the winding apparatus that can be used for the used magnetic core of high pressure, burst pulse high power devices (as: ion accelerator, magnetic switch, straight line transformer drive source, pulse transformer etc.) with the amorphous soft magnetic ribbon wound core.In particular, the present invention relates to a kind of with low cost, easy and simple to handle reliable, the coiling effect is satisfied integrates and apply and the winding apparatus of the amorphous alloy ribbon wound core of winding function, is suitable for very much the amorphous state magnetic core of high pressure, burst pulse high power devices required tape thickness 0.01～0.05mm, bandwidth 10～150mm and the coiling of nanocrystalline magnet core.
2, background technology
The used magnetic core component of high voltage narrow pulse power source adopts ceramic ferrite or silicon steel thin belt to make in the past, because the limitation of these two kinds of material properties and technology, their uses have been limited in many burst pulse high power occasions, domestic and international at present all the amorphous soft magnetic ribbon material wound core of serviceability excellence, for example iron-based non-crystalline alloy band Fe 78Si 9B 13, its Bs 〉=1.56T, resistivity 〉=130 μ Ω/cm, coercive force≤5A/m, Curie temperature 〉=370 ℃, preparation technology is simple, and cost is cheap relatively, ample supply of commodities on the market, thereby obtained extensive use.But amorphous soft magnetic alloy and nano-crystal soft magnetic alloy strip material are more crisp, and the counter stress sensitivity brings difficulty for the magnet ring coiling.
The coating winding apparatus of the known annular amorphous soft magnetic ribbon wound core that is used for high pressure, burst pulse high power devices generally is made up of parts such as coiled strip discharging frame, coating liquid bath, drying tunnel, winders, and structural representation is seen Fig. 1.Its discharging frame is unpowered, and by the pulling of coiling main shaft, band is broken easily, and the magnetic core density degree of being reeled is inhomogeneous; Amorphous alloy strip steel rolled stock face coat varied in thickness is big and be difficult for controlled (coating layer thickness is between 3～15 μ m), the back magnet ring duty ratio of reeling lower (the highest only 70%); It applies tape running speed below 200mm/s, because the whole winding speed of the influence of coating efficiency can't improve, maximum winding diameter is below 300mm.The coating winding apparatus that also has is made split, applies to separate with coiling, is wound into magnet ring again after applying into rouleau, the bigger specification magnet ring of can reeling like this, but its operation is cumbersome, inefficiency, and spillage of material is many, and winding quality is poor.
3, summary of the invention
The objective of the invention is problem at above-mentioned prior art existence, a kind of winding apparatus of amorphous alloy band magnet core is provided, solved because amorphous alloy ribbon fragility is very big and applied the problem that winding process brings, comprised that band is easily broken to cause that coiling work can't be carried out continuously, bad, the problems such as coating speed is low, the coiling duty ratio is low, coiling consistency difference of coating thickness control to magnetic core.
Amorphous soft magnetic alloy magnetic core up-coiler of the present invention comprises following part: the discharge mechanism that has drive unit; Prevent the material-storing box of band tension variations; The front end tension control mechanism of scalable thrust and rear end tension control mechanism; The constant temperature that temperature is adjustable applies liquid bath; Two kinds of mechanical type coating layer thickness control device; Electric heating constant temperature coated and dried device; Coating dielectric strength checkout gear; Coiling main shaft and rewinding dish; The magnet ring hold-down mechanism; Support and electric control system etc.
