Description
Technical Field
The invention belongs to the technical field of amorphous alloy, relates to a manufacturing method of an adhesive tape, and particularly relates to an amorphous adhesive tape, and a manufacturing method and application thereof.
Background
The amorphous alloy material has excellent electromagnetic properties, has the characteristics of high magnetic permeability and low iron loss, and is widely applied to the fields of transformers, mutual inductors and the like. In these fields of application, when amorphous alloy materials are used for iron cores, they are usually ring-shaped or ring-like and are often shaped by winding. A core that cannot be formed by winding, such as a motor stator, a motor rotor, and a sensor, needs to be manufactured by a sheet-punching method.
The difficulty in stamping amorphous alloy materials is mainly due to the thickness of the amorphous ribbon. The amorphous alloy material is formed by throwing high-temperature molten alloy through a single-roller cooling method, the thickness of the amorphous alloy is generally 10-50 mu m due to the characteristics of material characteristics and manufacturing process, and the thickness of a common silicon steel sheet is about 0.2-0.5mm, so that laminated iron cores with the same thickness are manufactured, the number of amorphous punching sheets is 4-20 times that of the silicon steel sheet, the production efficiency is greatly reduced, and the production cost is increased.
In addition, the thinner thickness of the amorphous alloy also affects the stamping cost. For example, the clearance between the male film and the female film of the stamping die is generally about 10% of the thickness of the plate, and for amorphous materials with thin thickness, the die clearance needs to be 1-5 μm, and if the clearance is small, the die machining precision and the punching precision are required to be high, which leads to the increase of the stamping cost; on the other hand, the abrasion of the punch is also aggravated, the service life of the punch is reduced, and the cost of the punching sheet is increased.
Moreover, the amorphous alloy has thinner thickness and lower rigidity, and cannot be fed in a silicon steel feeding mode, so that the stamping difficulty and cost are increased. Because the amorphous alloy strip is thin and low in rigidity, the strip is easy to be adsorbed on a die, and the feeding and blanking procedures are affected. Therefore, in order to reduce the cost of punching the amorphous alloy, it is necessary to increase the thickness of the amorphous alloy punched plate.
The method for laminating the strips into the plate with larger overall thickness comprises riveting, welding and bonding, and the amorphous alloy is a brittle material with poor ductility, so that the riveting cannot be performed; the welding mode is that adjacent strips are connected through welding spots, the strip layers near the welding spots are firmly connected, the interlayer connection cannot be realized in the area without the welding spots, and when the area without the welding spots is punched, the phenomena of dislocation and material jumping are easy to occur, so that the quality of a punched sheet is influenced. Bonding is one of the effective methods of laminating amorphous alloy strips into thick sheets.
In general, the manufacturing process of the multi-layer adhesive tape is online linear adhesion, equipment required by the process occupies large area, production efficiency is low, and manufacturing cost of the multi-layer adhesive tape is high. Meanwhile, the online adhesive tape is straight and has no curvature, after the online adhesive tape is wound, the deformation of each layer is different due to the bending effect, interlayer adhesive is easily damaged due to the stress effect, and the coil is easily cracked in the storage and transportation processes.
Therefore, the amorphous multi-layer adhesive tape based on adhesion and convenient for long-term storage and transportation, and the preparation method and application thereof are provided, and have important significance for reducing the cost of stamping amorphous alloy and improving the stamping precision and efficiency of amorphous alloy.
