Description
Foil processing device Technical Field The invention relates to a foil processing device. Background Conventionally, a foil processing apparatus for processing a metal foil into a foil having a predetermined shape has been proposed. Here, when the metal foil is made of a nanocrystalline soft magnetic material, the metal foil is brittle, and thus it is difficult to process the foil into a desired shape. From this point of view, for example, patent document 1 proposes a processing apparatus in which a metal foil of an amorphous soft magnetic material is cut into a foil shape while leaving a part of a connection portion to be connected to the metal foil. After the processing by the processing device, the metal foil is heat-treated so that the amorphous soft magnetic material becomes a nanocrystalline soft magnetic material, and the connection portion is cut. Patent document 1 Japanese patent application laid-open No. 2020-120426 Disclosure of Invention However, in the processing device of patent document 1, a metal foil made of an amorphous soft magnetic material is cut into a foil having a predetermined shape while a connecting portion is left, and then, when the metal foil of the amorphous soft magnetic material is subjected to heat treatment so as to be a nanocrystalline soft magnetic material, the foil is easily deformed. In view of this, it is preferable to cut the foil from the metal foil of the nanocrystalline soft magnetic material, but since the nanocrystalline soft magnetic material is brittle, the metal foil is broken before the foil is cut into a desired shape. The present invention has been made in view of the above-described points, and an object of the present invention is to provide a foil processing apparatus capable of stably processing a foil from a metal foil of a nanocrystalline soft magnetic material. In view of the above problems, a foil processing apparatus according to the present invention is a foil processing apparatus for processing a metal foil made of a nanocrystalline soft magnetic material into a foil having a predetermined shape. The processing device comprises a mounting table having a mounting surface on which the metal foil is mounted, a pressing rod which is vertically movable relative to the mounting table and has a pressing surface corresponding to the predetermined shape, and which presses the metal foil mounted on the mounting table, and a support base on which a pair of 1st support columns and a pair of 2nd support columns are erected, the mounting table being supported by the pair of 1st support columns and the pair of 2nd support columns, the pair of 1st support columns being separated in the 1st direction, and the pair of 2nd support columns being separated in the 2nd direction orthogonal to the 1st direction. The mounting table includes a processing table that is erected on the support base and has a processing surface corresponding to the shape of the foil piece as a part of the mounting surface formed at a position facing the pressing surface of the pressing lever, a pair of 1 st pivot members that are pivoted to the pair of 1 st support posts with the processing surface interposed therebetween and that have a part of the mounting surface formed thereon, and a pair of 2 nd pivot members that are pivoted to the pair of 2 nd support posts with the processing surface interposed therebetween and that have a part of the mounting surface formed thereon. The pair of 1 st pivot members are pivotally connected to the pair of 1 st support posts across the working surface to pivot about a parallel pair of 1 st pivot axes, and the pair of 2 nd pivot members are pivotally connected to the pair of 2 nd support posts across the working surface to pivot about a pair of 2 nd pivot axes orthogonal to each of the 1 st pivot axes. More preferably, the working device further includes a working lever that pushes up the pair of 1 st pivot members from below to pivot the pair of 1 st pivot members about the pair of 1 st pivot shafts. Each of the 2 nd pivot members includes a pair of pivot portions pivotally connected to the pair of 2 nd support columns, an arm portion connected to the pivot portions so as to span the pair of pivot portions and pushed up from below by the pair of 1 st pivot members by pivoting of the pair of 1 st pivot members, and a pivot processing portion extending from the arm portion to the processing surface between the pair of 1 st pivot members so as to form a part of the mounting surface. Furthermore, the hold-down bar may be constituted by a permanent magnet. Effects of the invention According to the invention, the metal foil is clamped between the clamping bar and the processing table. Since the pressing surface of the pressing bar and the processing surface of the processing table have shapes corresponding to the shapes of the foils, the region of the metal foil corresponding to the foils is fixed (restrained) by the pressing bar and the processing table.
