Embodiment 1
[0055] figure 1 It is an explanatory diagram showing the basic steps of the shearing method of the present invention.
[0056] exist figure 1 In the embodiment, the processed plate 1 is an electrode plate of a lithium ion battery in which an active material (non-metallic layer) 1b is laminated on both sides of a metal layer 1a made of copper or aluminum. The total plate thickness is 180 μm, among which the metal layer 1a is 20 μm, and the non-metal layer 1b is 80 μm.
[0057] Such as figure 1 As shown in (a), this workpiece 1 is mounted and fixed on a die 2 having a hole 2 a for shearing. Then, if figure 1 As shown in (b), the workpiece plate 1 is sheared by lowering the punch 3 disposed above the shearing hole 2 a.
[0058] In the embodiment, after the punch 3 touches the surface of the workpiece 1 , the punch 3 is stopped when the punch 3 is lowered to a position of 30 μm, that is, 17% of the thickness of the workpiece 1 . As a result, it was confirmed that the process...
Embodiment 2
[0063] figure 2 shows other embodiments of the present invention. This embodiment is an example of overlapping and cutting a plurality of sheets to be processed.
[0064] The plate to be processed 1 is an electrode plate of a lithium ion battery having a plate thickness of 180 μm, as in the previous embodiment, and eight sheets are stacked. That is, the overall thickness of the workpiece 1 is 1.44 mm.
[0065] In the embodiment, with respect to the eight overlapping processed plates 1, after the punch 3 touches the surface of the processed plate 1, the punch 3 is lowered to the position of 200 μm, that is, the eight overlapping processed plates 1 The stage at the position of 14% of the overall thickness makes the punch 3 stop. As a result, it was confirmed that all the eight processed sheet materials 1 were completely cut.
Embodiment 3
[0067] image 3 shows another embodiment of the present invention. This embodiment is an example of cutting a metal thin plate using a punch and a die.
[0068] First, if image 3 As shown in (a), a metal thin plate is placed on the die 2 as the workpiece 7 , and an intermediate plate 8 having at least one non-metal layer is placed on the workpiece 7 . In the embodiment, the processed plate 7 is a titanium plate with a plate thickness of 20 μm, and a polypropylene plate with a thickness of 150 μm is used as the intermediate plate 8 . As the material of the intermediate plate 8, in addition to polypropylene, acrylic resin, PET, polycarbonate, phenolic resin, plastic, fluorinated resin, epoxy resin, polyurethane, polyvinyl chloride, polyamide, polyethylene, chlorine Non-metallic layers such as vinyl, hard rubber, paper, glass plates, asphalt, and synthetic fibers, and laminates of these non-metallic layers or laminates of these non-metallic layers and metal layers can also be...
