Description

Technical Field

[0001] This invention relates to a foil processing apparatus. Background Technology

[0002] Conventional processing apparatuses have been proposed for shaping metal foil into foil sheets of a specified shape. However, when the metal foil is made of a nanocrystalline soft magnetic material, it is difficult to process it into the desired shape due to its brittleness. From this perspective, for example, Patent Document 1 discloses a processing apparatus in which, for amorphous soft magnetic metal foil, the foil is cut into foil sheet shape while retaining a portion of the connecting portion to the metal foil. After processing by this apparatus, the metal foil is heat-treated to transform the amorphous soft magnetic material into a nanocrystalline soft magnetic material, and the connecting portion is then cut off.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2020-120426 Summary of the Invention

[0004] However, the processing apparatus in Patent Document 1 cuts a metal foil made of amorphous soft magnetic material into foil sheets of a predetermined shape while retaining the connecting portions. Then, if the amorphous soft magnetic material metal foil is heat-treated to become a nanocrystalline soft magnetic material, the foil sheets are easily deformed. In view of this, it is preferable to cut foil sheets from nanocrystalline soft magnetic material metal foil; however, since nanocrystalline soft magnetic materials are brittle, the metal foil may break before being cut into the desired shape.

[0005] The present invention was made in view of this purpose, and its object is to provide a foil processing apparatus capable of stably processing foil sheets from metal foils of nanocrystalline soft magnetic materials.

[0006] In view of the aforementioned issues, the foil processing apparatus of the present invention is a foil processing apparatus for processing a metal foil made of a nanocrystalline soft magnetic material into a foil sheet of a specified shape.

[0007] The processing apparatus comprises: a platform having a mounting surface for holding the metal foil; a clamping rod that can move freely up and down relative to the platform and has a clamping surface corresponding to the prescribed shape for clamping the metal foil placed on the platform; and a support base having a pair of first support columns and a pair of second support columns erected thereon, and the platform being supported by the pair of first support columns and the pair of second support columns, the pair of first support columns being separated in a first direction, and the pair of second support columns being separated in a second direction orthogonal to the first direction.

[0008] The mounting platform comprises: a processing table erected on the support base, and having a processing surface corresponding to the shape of the foil as part of the mounting surface at a position opposite to the pressing face of the pressing rod; a pair of first pivoting members pivotally connected to the pair of first support columns, clamping the processing surface, and having part of the mounting surface; and a pair of second pivoting members pivotally connected to the pair of second support columns, clamping the processing surface, and having part of the mounting surface.

[0009] The pair of first pivoting components, clamping the machined surface, are pivotally connected to the pair of first support columns to pivot about a pair of parallel first pivot axes. The pair of second pivoting components, clamping the machined surface, are pivotally connected to the pair of second support columns to pivot about a pair of second pivot axes orthogonal to each of the first pivot axes.

[0010] As a more preferred embodiment, the processing apparatus further includes a processing control lever that pushes up the pair of first pivoting members from below, causing the pair of first pivoting members to pivot about the pair of first pivoting axes.

[0011] Each of the second pivoting members includes: a pair of pivot portions pivotally connected to the pair of second support columns; an arm portion connected to the pivot portions across the pair of pivot portions and pushed up from below by the pair of first pivoting members through pivoting; and a pivoting processing portion extending from the arm portion to the processing surface between the pair of first pivoting members, forming part of the mounting surface. Furthermore, the clamping rod may be made of a permanent magnet.

[0012] Invention Effects

[0013] According to the present invention, a metal foil is clamped between a clamping rod and a processing table. The clamping surface of the clamping rod and the processing surface of the processing table are shaped to correspond to the shape of the foil, thus fixing (constraining) the area of ​​the metal foil corresponding to the foil sheet by the clamping rod and the processing table. In this state, by pivoting a pair of first pivoting members and a pair of second pivoting members, the portion of the metal foil except for the portion clamped by the clamping rod and the processing table breaks and fractures due to bending stress. As a result, foil sheets of the desired shape can be easily processed from the metal foil. Attached Figure Description

[0019] The following is for reference. Figures 1-5 The foil processing apparatus 1 according to the embodiments of the present invention will be described.

[0020] 1. Regarding metal foil F

[0021] The processing apparatus 1 according to this embodiment is an apparatus for processing a metal foil F made of a nanocrystalline soft magnetic material into a foil sheet Fb of a predetermined shape. Here, the metal foil F is made of a nanocrystalline soft magnetic material. As a nanocrystalline soft magnetic material, examples include materials made of at least one magnetic metal selected from the group consisting of Fe, Co, and Ni, and at least one non-magnetic metal selected from the group consisting of B, C, P, Al, Si, Ti, V, Cr, Mn, Cu, Y, Zr, Nb, Mo, Hf, Ta, and W. As representative materials of amorphous soft magnetic materials or nanocrystalline soft magnetic materials, examples include FeCo alloys, FeNi alloys, FeAl alloys, FeSi alloys, FeTa alloys, and FeZr alloys. In the case of Fe alloys, it is preferable that the Fe content is 80 at% or more.

[0022] The nanocrystalline soft magnetic materials described in this specification are soft materials with a nanocrystalline structure as their main structure. In a nanocrystalline structure, diffraction peaks are observed at positions corresponding to the lattice spacing of the crystal planes. In nanocrystalline soft magnetic materials, nanocrystals refer to grains with a full width at half maximum (FWHM) of the diffraction peaks obtained from X-ray diffraction and a grain size less than 1 μm, calculated using the Scherrer formula.

[0023] The thickness of the metal foil F is preferably in the range of 10 μm or more and 100 μm or less (e.g., 20 μm). The metal foil F is a foil that is crystallized from an amorphous soft magnetic material to a nanocrystalline soft magnetic material by heating. However, compared with nanocrystalline soft magnetic materials, amorphous soft magnetic materials are ductile, so sometimes after processing the metal foil of the amorphous soft magnetic material into a foil sheet of a specified shape, the foil sheet is heated to crystallize it. However, when the amorphous soft magnetic material is crystallized into a nanocrystalline soft magnetic material, the amorphous soft magnetic material foil itself heats up and shrinks through crystallization, so it is sometimes difficult to maintain the shape of the foil sheet during shrinkage. Therefore, it is also possible to consider using a metal foil F of nanocrystalline soft magnetic material (see reference). Figure 1 ) is processed into foil Fb (reference) Figure 5 However, since nanocrystalline soft magnetic materials are brittle, the metal foil F made of nanocrystalline soft magnetic materials is prone to breakage during processing. In view of this, in this embodiment, an apparatus is proposed to process a metal foil F made of nanocrystalline soft magnetic material into a foil sheet Fb of a specified shape using the following processing apparatus 1.

[0024] 2. Processing apparatus for foil Fb 1

[0025] like Figure 1 As shown, the processing apparatus 1 is an apparatus for processing a metal foil F made of a nanocrystalline soft magnetic material into a foil sheet Fb of a specified shape. The processing apparatus 1 includes a stage 10, a clamping mechanism 20, a support base 30, and a processing control lever 40.

[0026] 2-1. Regarding the support base 30

[0027] The processing apparatus 1 according to this embodiment has a mounting platform 10 and a clamping mechanism 20 mounted on a support base 30. Specifically, a pair of first support columns 31, 31 separated in a first direction D1 and a pair of second support columns 32, 32 separated in a second direction D2 orthogonal to the first direction D1 are erected on the support base 30. The support base 30 supports the mounting platform 10 by the pair of first support columns 31, 31 and the pair of second support columns 32, 32. Furthermore, a support column 24 is erected on the support base 30, and the support base 30 supports the clamping rod 21, etc., which will be described later, by the support column 24.

[0028] 2-2. Regarding the mounting platform 10

[0029] The mounting stage 10 has a mounting surface 10a for mounting the metal foil F. In this embodiment, the mounting stage 10 includes: a processing stage 13 for processing the metal foil F into a foil sheet Fb; and a pair of first pivoting members 11, 11 and a pair of second pivoting members 12, 12, which surround the processing stage 13 from four directions.

[0030] A processing table 13 is erected on a support base 30. On the processing table 13, a processing surface 13a corresponding to the shape of the foil Fb is formed on a portion of the placement surface 10a at a position opposite to the clamping surface 21a of the clamping rod 21. In this embodiment, the processing surface 13a has a surface shape consistent with the shape of the foil Fb to be processed. The processing surface 13a is rectangular, but it is not particularly limited as long as it is a shape that does not hinder the pivoting by the first pivoting member 11 and the second pivoting member 12 described later, such as a fan shape or a trapezoid. In this case, the first pivoting axis L1 and the second pivoting axis L2, which are the pivoting axes of the first pivoting member 11 and the second pivoting member 12 described later, are preferably tangents to the processing surface 13a having these shapes.

[0031] In this embodiment, a pair of first pivoting members 11, 11 are arranged to sandwich the machined surface 13a in the second direction D2. Each first pivoting member 11 is pivotally connected to a pair of first support columns 31, 31. Specifically, the pair of first pivoting members 11, 11, sandwiching the machined surface 13a, are pivotally connected to a pair of first support columns 31, 31 to pivot about a pair of first pivot axes L1, L1 parallel to the first direction D1.

[0032] That is, in this embodiment, a pair of first pivoting members 11, 11 respectively pivot around a corresponding first pivoting axis L1 of a pair of first pivoting axes L1, L1. A portion of a mounting surface 10a is formed on the first pivoting member 11. A portion of the mounting surface 10a of the first pivoting member 11 becomes the bending surface 16a of the metal foil F, which will be described later, and the first pivoting member 11 pivots in the bending direction of the metal foil F mounted on the mounting surface 10a. In this embodiment, each first pivoting axis L1 is set to pass through a portion of the periphery 13b of the processing surface 13a (the periphery 13b along the first direction D1), and the first pivoting axes L1 are axes parallel to each other in the horizontal direction.

[0033] In this embodiment, each first pivoting member 11 includes a pivoting machining section 16A that forms its main body. First pivoting members 14A, pivotally connected to the first support column 31, are mounted at both ends of the pivoting machining section 16A in the first direction D1. The first pivoting members 14A are pivotally connected to the first support column 31 via pivoting pins 19A. A method for... Figure 1 The bending surface 16a constitutes a portion of the mounting surface 10a of the planar metal foil F in the shown state. The bending surface 16a is formed on the same plane as the machining surface 13a of the machining table 13, and is formed at a position adjacent to the machining surface 13a. During the processing described later (see details...), Figure 3 and Figure 4Through the pivoting of the first pivoting member 11, the bending surface 16a is tilted relative to the processing surface 13a in such a way that the outer edge parallel to the first pivoting axis L1 rotates upward around the first pivoting axis L1.

[0034] In this embodiment, a pair of second pivoting members 12, 12 are arranged to sandwich the machined surface 13a in the first direction D1. Each second pivoting member 12 is pivotally connected to a pair of opposing second support columns 32, 32. Specifically, the pair of second pivoting members 12, 12, sandwiching the machined surface 13a, are pivotally connected to a pair of second support columns 32, 32 to pivot about a pair of second pivot axes L2, L2 parallel to the second direction D2. Each second pivot axis L2 is orthogonal to each first pivot axis L1.

[0035] That is, in this embodiment, a pair of second pivoting members 12, 12 respectively pivot around a corresponding second pivoting axis L2 of a pair of second pivoting axes L2, L2. A portion of a mounting surface 10a is formed on the second pivoting member 12. A portion of the mounting surface 10a of the second pivoting member 12 becomes the bending surface 16a of the metal foil F, which will be described later, and the second pivoting member 12 pivots in the bending direction of the metal foil F mounted on the mounting surface 10a. In this embodiment, each second pivoting axis L2 is set to pass through a portion of the periphery 13b of the processing surface 13a (the periphery 13b along the second direction D2), and the second pivoting axes L2 are axes parallel to each other in the horizontal direction.

[0036] Here, each of the second pivoting components 12 includes: a pair of pivot portions 14, 14, which are pivotally connected to a pair of second support columns 32, 32 respectively; an arm portion 15, which is connected (fixed) to the pivot portions 14, 14 in a manner spanning the pair of pivot portions 14, 14; and a pivoting machining portion 16B, which is fixed to the arm portion 15. Each pivot portion 14 is pivotally connected to the second support column 32 via a pivot pin 19B, extends from the pivot pin 19B in an inclined upward direction along the first direction D1, and is fixed to the arm portion 15 at its front end. The arm portion 15 is freely mounted on the pivoting machining portion 16A of the first pivoting component 11, and is pushed up from below by the pair of first pivoting components 11, 11 by the pivoting of the pair of first pivoting components 11, 11, corresponding to the pushing action performed by the machining control lever 40 described later. In the arm 15, a recess, namely a clearance portion 15a, is formed at the center along the second direction D2. The clearance portion 15a prevents the arm 15 from contacting the clamping rod 21, which will be described later, when the arm 15 is pushed up.

[0037] The pivoting machining section 16B extends to the machining surface 13a between a pair of first pivoting members 11, 11, in a manner that forms part of the mounting surface 10a. A [missing information - likely referring to a machining process] is formed on the pivoting machining section 16B. Figure 1The bending surface 16a constitutes a portion of the mounting surface 10a of the planar metal foil F in the shown state. The bending surface 16a is formed on the same plane as the machining surface 13a of the machining table 13, and is formed at a position adjacent to the machining surface 13a. During the processing described later (refer to...) Figure 3 and Figure 4 Through the pivoting of the first pivoting member 11, the bending surface 16a is tilted relative to the machining surface 13a in such a way that the arm 15 rotates upward around the second pivoting axis L2.

[0038] 2-3. Regarding the control lever 40 for machining

[0039] The processing apparatus 1 also includes a processing control lever 40, which pushes up a pair of first pivoting members 11, 11 from below, causing the pair of first pivoting members 11, 11 to pivot about a pair of first pivot axes L1, L1. The processing control lever 40 is pivotally connected to a first support column 31 by a fastening pin 43. The processing control lever 40 includes: a pressing button 41 for the operator to press the processing control lever 40; and a pair of pivoting arms 42, 42, which extend to the pair of first pivoting members 11, 11 respectively, by clamping a first support column 31 from both sides of the pressing button 41.

[0040] Each pivot arm 42 is pivotally connected to a first support post 31 by a fastening pin 43. At the front end of each pivot arm 42, a pusher 44 that pushes up the first pivot member 11 extends upward toward the first pivot member 11 from below.

[0041] Specifically, the front end portions (upper surface portions) of a pair of push-up portions 44 are positioned in the second direction D2, sandwiching the first pivot axes L1, L1, and are in free sliding contact with the bottom surface of the first pivot member 11. Thus, if an operator presses the button 41, each pivot arm 42 pivots around the fastening pin 43. As a result, each push-up portion 44 can push up the outer edge of the first pivot member 11, L1, parallel to the first pivot axis L1, causing the pair of first pivot members 11 to rotate (pivot) upwards simultaneously around the first pivot axis L1.

[0042] 2-4. Regarding the clamping mechanism 20

[0043] The clamping mechanism 20 includes a support column 24 erected on the support base 30. A clamping rod 21 is mounted on the support column 24 via a guide member 25 and a support body 26, allowing it to move freely up and down. Thus, the clamping rod 21 can move freely up and down relative to the mounting table 10. The clamping rod 21 has a clamping surface 21a as its front end face, corresponding to a predetermined shape of the foil Fb, and clamps the metal foil F placed on the mounting table 10. In this embodiment, the periphery 13b of the processing surface 13a coincides with the periphery of the clamping surface 21a.

[0044] As long as the metal foil F can be pressed firmly, the clamping rod 21 can be made of a metal material such as stainless steel or aluminum. In this embodiment, the clamping rod 21 is made of a permanent magnet. Therefore, when the clamping rod 21 is raised, the foil Fb adsorbed on the clamping rod 21 can be easily detached from the clamping rod 21.

[0045] Specifically, a connecting guide 22, which connects to a cylindrical base end rod 23, is installed at the base end of the clamping rod 21. A guide member 25 is installed near the center in the height direction of the support column 24. A guide frame 25a for sliding the connecting guide 22 in the vertical direction and a mounting arm 25b extending horizontally relative to the guide frame 25a are formed on the guide member 25. The mounting arm 25b is mounted to the support column 24 via a fastener 71. At the upper end of the support column 24, the top plate 26a of the support body 26 is fixed via a fastener 72, and a guide block 26b is fixed on the top plate 26a to freely guide the base end rod 23 in the vertical direction.

[0046] A pair of pivot joints 27b, 27b are pivotally mounted on the base end rod 23, and these pivot joints 27b, 27b are formed on the handle 27. A gripping part 27a for the operator to hold is provided on the handle 27. The pivot joint 27b is an L-shaped portion, its front end of which is mounted to the base end rod 23, and the center of the bent portion is mounted to the guide block 26b of the support body 26 via a connecting rod member 28. Thus, if from... Figure 1 In the state shown, while the operator holds the grip 27a, the grip 27a rotates to become Figure 2 In the state shown, the base rod 23 descends, and the clamping rod 21 can clamp the metal foil F placed on the mounting table 10 (processing table 13).

[0047] 3. Processing methods for foil Fb

[0048] The following is for reference. Figures 1-5 The processing method for processing a metal foil F made of nanocrystalline soft magnetic material into a foil sheet Fb of a specified shape is described.

[0049] First, such as Figure 1 As shown, a metal foil F is placed on the placement surface 10a of the placement stage 10. In this state, the clamping rod 21 (the clamping surface 21a) is in the raised position relative to the placement stage 10, and the pressing button 41 of the processing control lever 40 is also in the raised position.

[0050] Next, as Figure 2 As shown, the metal foil F placed on the mounting surface 10a of the mounting stage 10 is pressed by the clamping rod 21. Specifically, if from... Figure 1In the state shown, while the operator holds the gripping part 27a of the handle 27, the gripping part 27a is rotated 180° to become Figure 2 In the indicated state, the base rod 23 descends. At this time, the connecting guide 22, connected to the base rod 23, is guided downwards relative to the guide frame 25a of the guide member 25. Thus, the metal foil F placed on the mounting table 10 (processing table 13) can be precisely pressed by the clamping rod 21. At this time, it is equivalent to... Figure 5 The area of ​​the metal foil F of the foil Fb shown is clamped and fixed between the processing surface 13a of the processing table 13 and the clamping surface 21a of the clamping rod 21.

[0051] Next, if the workers from Figure 2 Starting from the state shown, according to Figure 3 and Figure 4 In the sequence shown, pressing down on the button 41 causes each pivot arm 42 to pivot around the fastening pin 43. As a result, the front end of each push-up portion 44 slides against the back of the first pivot members 11, 11 while pushing up the outer edge of the first pivot members 11, 11 that is parallel to the first pivot axis L1. Consequently, the pair of first pivot members 11, 11 can simultaneously rotate (pivot) upwards around the first pivot axis L1.

[0052] Here, each arm 15 of the pair of second pivot members 12 is mounted on the upper surface portion of both ends of the first pivot member 11, allowing free contact or separation. Through the pivoting of the pair of first pivot members 11, 11, corresponding to the pushing action performed by the pushing part 44 of the machining control lever 40, each arm 15 is pushed up from below while sliding against the pair of first pivot members 11, 11. As a result, the second pivot members 12, 12 can simultaneously rotate upwards (pivot) around the second pivot axis L2.

[0053] Through this series of actions, a portion of the mounting surfaces 10a of the pair of first pivoting members 11, 12 functions as a bending surface 16a for bending the metal foil F using the constrained portion of the metal foil F as a fulcrum. Simultaneously, a portion of the mounting surfaces 10a of the pair of second pivoting members 12, 12 functions as a bending surface 16a for bending the metal foil F using the constrained portion of the metal foil F as a fulcrum. The metal foil F is made of a brittle material, which is composed of a nanocrystalline soft magnetic material, therefore, when... Figure 3 stage to Figure 4 During this stage, it breaks due to the applied bending stress. On the other hand, the area of ​​the metal foil F corresponding to the foil Fb is clamped and fixed between the processing surface 13a of the processing table 13 and the clamping surface 21a of the clamping rod 21, so no cracks will occur in this area, such as Figure 5 As shown, a foil Fb without breakage can be obtained.

[0054] According to this embodiment, a metal foil F is clamped between a clamping rod 21 and a processing table 13. The clamping surface 21a of the clamping rod 21 and the processing surface 13a of the processing table 13 are shaped to correspond to the shape of the foil Fb. Therefore, in the metal foil F, a region corresponding to the foil Fb is fixed by the clamping rod 21 and the processing table 13. In this state, by simultaneously pivoting a pair of first pivoting members 11, 11 and a pair of second pivoting members 12, 12, the portion of the metal foil F, except for the portion clamped by the clamping rod 21 and the processing table 13, breaks and fractures due to bending stress. As a result, a foil Fb of the desired shape can be easily processed from the metal foil F.

[0055] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments, and various design changes can be made without departing from the spirit of the present invention as set forth in the claims.

[0056] In addition, in this embodiment, the foil is processed by pivoting a pair of first pivoting members and a pair of second pivoting members simultaneously in four directions of the processing surface using a processing control lever. However, for example, the first pivoting member and the second pivoting member can be pivoted individually without using the processing control lever.

[0057] Moreover, since the foil is rectangular, the processing surface of the processing table and the clamping surface of the clamping rod are also rectangular. However, as long as bending stress can be applied to the metal foil while it is clamped between the processing surface and the clamping surface, it is of course possible to process it into other shapes such as fan-shaped or trapezoidal foil to replace the rectangle.
