本発明は、変圧器、リアクトル等の鉄心に用いる非晶質
磁性薄帯の切断方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for cutting an amorphous magnetic ribbon used for iron cores of transformers, reactors, etc.

薄帯を多数切断できる加工方法の開発が望まれている。Amorphous magnetic ribbon, which is produced by rapidly cooling an alloy containing iron and boron as its main components and semimetallic elements such as silicon and carbon, has excellent properties such as extremely low iron loss. Because of its magnetic properties, it is expected to save energy when used in transformer cores, etc., and many prototype studies are underway. However, this amorphous magnetic ribbon has a thickness of about 3
0 μm, which is about 1/10 of the silicon steel strip used conventionally, and therefore, using this material, a laminated iron core of 417 mm
If this is the case, the number of punched sheets will be very large. Moreover, the amorphous magnetic ribbon is extremely hard, with a Vickers hardness of 1000.
If the amorphous magnetic ribbon is cut many times with a punching die, the die will be severely damaged by wear. For this reason, it is necessary to polish the punching die every time several hundred pieces of amorphous magnetic ribbon are cut, which is a major problem that hinders the practical application of the laminated iron core. Therefore, the application of amorphous magnetic ribbons to transformers, etc. is limited to single-wound core structures, and laminated cores are difficult, so it is difficult to develop processing methods that can cut large numbers of amorphous magnetic ribbons. desired.
本発明はこのような状況にかんがみてなされたものであ

題を起さない切断方法を提供することを目的としている
。The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a cutting method that does not cause damage to the punching die even when a large number of amorphous magnetic ribbons are cut.

る。The cutting method of the present invention is characterized by heating the portion of the amorphous magnetic ribbon to be cut to make the material of this portion brittle, and applying an external force to this brittle portion to cause it to break.

In the figure, an amorphous magnetic ribbon l wound into a coil is
A roller 4 provided at the tip of the roller 2 and 3
．． Focus on number 5 and move it from left to right in the diagram. Here, as shown in FIG. 2, a thin wire-shaped heater 6 is embedded in the outer peripheral surface of the roller 2 along the axial direction of the roller 2. This area is heated by touching it. As a result, the cut portion 1a of the amorphous magnetic ribbon 1 becomes locally brittle as shown by diagonal lines due to an increase in temperature. It is desirable that the temperature at this time be raised to the crystallization temperature of the amorphous magnetic ribbon, but if the temperature is lower than that, problems will occur.

断させることができる。The amorphous magnetic ribbon l, which is thus heated by the thin wire heater 6 attached to the roller 2 and has nine linear portions, passes through the roller 4.5 and then has a smaller diameter. The curve imparts deformation through the roller 7 and the guide 8 disposed outside of it. In this song, the amorphous magnetic ribbon 1 is broken by deformation to form a punched plate for the laminated core, which is successively laminated into the stopper 11 through rollers 9 and 10. . By setting the diameter of the roller 7 to about 10 mm, which is smaller than the diameters of the other rollers, the amorphous magnetic ribbon 1 can be bent and broken.

切断部を破断させることができる。Note that the portion of the amorphous magnetic ribbon to be cut can also be heated with laser light. FIG. 3 shows an example of this case, in which the laser beam emitted from the laser light source 12 is directed by a mirror 13, converged by a lens 14, and applied to the part to be cut of the amorphous magnetic ribbon 1 that is running. Furthermore, by changing the angle of the mirror 13, the amorphous magnetic ribbon 1 can be locally heated in a linear manner. Moreover, not only bending deformation but also tensile force can cause amorphous magnetic ribbon 1. The part to be cut that has been heated at t7 can be broken.

Since the amorphous magnetic thin ribbon is cut by breaking the H portion, it is possible to cut the amorphous magnetic ribbon many times very easily without worrying about damage to the punching die or the like.
