Technical Field

The invention relates to the technical field of production and processing of amorphous strips, in particular to a three-dimensional winding and forming device for amorphous strips of an amorphous alloy three-dimensional wound core transformer.

Background

The amorphous alloy material has excellent physical properties such as high efficiency, low loss, high magnetic permeability and the like, promotes the development of electronic components in the directions of high frequency, high efficiency, energy conservation and miniaturization, and realizes partial replacement of materials such as traditional silicon steel, permalloy and the like. Particularly, the three-dimensional coiled iron core distribution transformer which is made by coiling the amorphous alloy strip in the power technology has the characteristics of high strength, three-phase balance, uniform temperature rise, short circuit resistance, low noise, material saving and small magnetic leakage, so that the seamless connection gas is obviously reduced, the magnetic resistance is greatly reduced, the no-load current is obviously weakened, and the transformer has become the main development direction of the transformer industry towards green environmental protection and energy saving.

The amorphous strip is required to be complete and not torn, broken and the tension of the wound strip is required to be constant as much as possible in the winding process of the iron core of the amorphous strip three-dimensional wound iron core transformer, so that the winding tightness of the amorphous strip three-dimensional wound iron core, no seam of the iron core after winding and small air gap loss are ensured, therefore, the winding quality of the strip must be controlled in the three-dimensional coil process of the amorphous strip, a general amorphous three-dimensional wound iron core needs three amorphous strips wound by independent rectangular inner tubes to be spliced into a three-dimensional structure, each rectangular inner tube is wound with more than ten thousand meters of amorphous strips, the amorphous strips are wound layer by clinging to the rectangular single-frame inner tube in the winding process, and the single-frame inner tube tool moves correspondingly in the axial direction along with the increasing number of the winding layers, so. The traditional winding method of the common strip can be finished by simply driving the strip by coil equipment because the processed material is high in strength, the stress condition of the strip does not need to be considered, but the amorphous alloy material is crisp in texture and very thin in thickness, the traditional winding method easily causes the phenomenon that the strip stress is uneven because the inner layer strip is tightly jointed and the joint tension of the outer layer strip is gradually reduced, particularly the strip is broken because the strip is slightly clamped in the layer-by-layer winding process on a single-frame inner tube to cause the steep increase of the tension, and the production efficiency and the final use performance of the three-dimensional wound core transformer are directly influenced by the uneven stress of the strip and the breakage of the strip in the winding process. At present, a high-precision, stable and quick amorphous strip constant-tension three-dimensional winding device aiming at the constant-tension three-dimensional winding processing of the amorphous strip is not developed.

Therefore, there is a need in the art for a new solution to solve the above problems.
