Definitions

  • the present invention relates to a method of shearing a thin plate, and more specifically to a method for forming a product by shearing a thin plate with a thickness of about 0.5 mm or less, which is made of a metal or prepared by laminating one or more non-metal layers on one or respective ones of opposite surfaces of a metal layer.
  • the workpiece plate is subjected to shearing by placing a workpiece plate on a die having a punch hole, and moving a punch disposed just above the punch hole downwardly to allow a distal end of the punch to be fitted into the punch hole.
  • the punch and the die are disposed upside down, i.e., the punch is disposed just below the die, and the die is moved instead of the punch.
  • Non-Patent Document 1 discloses an adequate relationship between a thickness of a workpiece plate, and a gap between a punch and a die (punch hole) for punching the workpiece plate (the gap will hereinafter be referred to simply as "clearance").
  • an adequate clearance is described as about 5 to 10% of the thickness of the workpiece plate.
  • the clearance when the workpiece plate has a thickness of 1 mm, the clearance is in the range of about 50 to 100 ⁇ m. As long as the clearance is such a value, it is easy to fabricate a forming tool, etc. However, when the workpiece plate has a smaller thickness, e.g., a thickness of 20 ⁇ m, the adequate clearance is reduced to 1 to 2 ⁇ m, so that a high level of fabrication technique, such as precision machining, is required for a forming tool, which leads to a problem of an increase in cost.
  • a punching operation using a forming tool fabricated to have a narrowed clearance involves other problems.
  • One problem is a reduction in usable life of the forming tool due to wear of the punch and the die.
  • a narrower clearance leads to a higher frequency of contact between the punch and the die in elastic deformation ranges thereof, which accelerates wear thereof.
  • the punch and the die are deformed beyond the elastic deformation ranges during the contact therebetween, a problem of chipping will also occur.
  • Another major problem is a problem with debris to be generated from a workpiece plate during punching. This problem becomes prominent when the workpiece plate is a laminated plate comprised of a metal layer and a non-metal layer. Debris generated from a workpiece plate is trapped between the punch and the die, which causes various problems, such as a problem of an increase in force required for punching, and a problem of an increase in frequency of cleaning required for the punch and the die. Moreover, the debris is likely to cause breakage of the forming tool.
  • the conventional punching method has another problem. Specifically, along with punching of a workpiece plate, particularly a metal plate, depending on its compatibility with a forming tool, adhesion of the workpiece plate is likely to occur in a punch. It is possible to prevent the adhesion problem to some extent by coating a punch and a die with ceramics, DLC (Diamond-Like Carbon) or the like. However, in a forming tool having a narrow clearance, only a temporary effect can be obtained because large wear occurs in a punch and a die due to a sliding movement therebetween.
  • DLC Diamond-Like Carbon
  • Still another problem is deterioration in quality of an outer edge of a punched-out portion of the workpiece plate (product portion). This is because, after punching the workpiece plate, the punched-out portion is moved to a dead center position of the punch while rubbing against an inner surface of the die, i.e., placed in a rubbing state through until it is separated from the die.
  • Non-Patent Document 1 A. Hashimoto, "Press Operations & Die Machining Methods New Edition", 7th Edition, Nikkan Kogyo Shimbun, Ltd., April 30, 1975, p 35
  • the inventor found that, in a thin plate prepared by laminating one or more non-metal layers on one or respective ones of opposite surfaces of a metal layer, the thin plate is fully sheared before a punch penetrates through the thin plate and becomes fitted into a shearing hole of a die.
  • the present invention has been made based on the above finding. Specifically, the present invention provides a method of shearing a thin plate prepared by laminating one or more non-metal layers on one or respective ones of opposite surfaces of a metal layer. The method comprises: placing the thin plate between a punch and a die having a shearing hole; and relatively moving the punch toward and with respect to the shearing hole to thereby shear the thin plate, wherein the relative movement of the punch is stopped to complete the shearing, before the punch penetrates through the thin plate and becomes fitted into the shearing hole.
  • the punch is not fitted into the die, so that it is not necessary to severely adjust a clearance as in the conventional punching method designed to allow the punch to be fitted into the die.
  • the clearance may be set to a zero clearance, or a minus clearance in which an outer diameter of the punch is set to be greater than an inner diameter of the die, as well as an usual plus clearance.
  • it is not necessary to severely adjust a clearance based on precision machining of a forming tool (punch and die), so that it becomes possible to easily fabricate the forming tool and reduce a fabrication cost of the forming tool.
  • each of the punch and the die becomes less likely to be worn, which provides extended usable life of the forming tool. Further, a displacement of a sheared portion of a workpiece plate is reduced, and thereby an amount of debris to be generated is reduced.
  • the conventional method also has a problem that, along with a vertical movement of the punch, a metal portion of a workpiece plate in contact with the punch adheres to the punch. It is difficult to remove the adhered metal component. If it is tried to remove the adhered metal component by rubbing or scraping, or using chemicals, a surface of the punch will have scars, or higher roughness, or alteration due to corrosion.
  • the adhesion phenomenon occurs after 100 shots at the latest, or after only 5 to 10 shots at the earliest.
  • the shearing can be performed without bringing the punch into direct contact with a metal portion of a workpiece plate, so that it becomes possible to prevent the workpiece plate from adhering to the punch.
  • a shearing state can be excellently maintained, and the thin plate can be sheared with high quality.
  • a forming tool there is no need to fabricate a forming tool with a maximally narrowed clearance which causes difficulty in fabrication and leads to a high cost, and therefore there is no need to take a high cost for fabrication of a forming tool.
  • the shearing method of the present invention is essentially different from the conventional half blanking/reversed blanking technique, in that the shearing method is designed to fully shear a workpiece plate by a single shearing operation.
  • the punch is stopped at a position corresponding to a depth in the thin plate which is equal to or greater than a thickness of the metal layer and equal to or less than a total thickness of the one or more non-metal layers. If the depth corresponding to the stop position of the punch is less than the thickness of the metal layer, a possibility to fail to complete the shearing of the thin plate will be increased. Further, if the depth is greater than the total thickness of the one or more non-metal layers, chipping in the punch and the die, an increase in amount of debris and/or adhesion of a metal component of the thin plate to the punch will occur, which is likely to cause difficulty in sufficiently obtain the effects of the present invention.
  • the shearing method of the present invention can also be applied to a thin plate stack formed by stacking a plurality of the thin plates on each other.
  • the thin plate stack is placed between the punch and the die, and the relative movement of the punch is stopped to complete the shearing, before the punch penetrates through the thin plate stack and becomes fitted into the shearing hole.
  • the plurality of thin plates can be simultaneously sheared to provide enhanced productivity.
  • a step of laminating respective sheared portions of the thin plates can be omitted by simultaneously shearing the laminated thin plates.
  • the number of the thin plates capable of being simultaneously sheared is about 10 at a maximum, in view of quality of a cut (sheared) surface of a workpiece plate. If the number is excessively increased, the cut surface will be gradually roughened, so that it becomes difficult to use resulting products in the field requiring high quality.
  • the punch is stopped at a position corresponding a depth in the thin plate stack which is equal to or greater than a total thickness of the metal layers of the thin plate stack (a sum of respective thicknesses of the metal layers in the plurality of staked thin plates) and equal to or less than a total thickness of the non-metal layers of the thin plate stack (a sum of respective thicknesses of the non-metal layers in the plurality of staked thin plates).
  • the shearing method of the present invention can also be applied to shearing using a die cutter and an anvil roll.
  • the present invention provides a method of shearing a thin plate prepared by laminating one or more non-metal layers on one or respective ones of opposite surfaces of a metal layer.
  • the method comprises: inserting the thin plate between a die cutter provided with a convex push-cutting blade on a surface thereof, and an anvil roll provided with a shearing recess at a position corresponding to the convex push-cutting blade; and rotating and pressing the convex push-cutting blade of the die cutter toward the shearing recess of the anvil roll to thereby shear the thin plate, wherein the thin plate is sheared without causing the convex push-cutting blade of the die cutter to penetrate through the thin plate and become fitted into the shearing recess of the anvil roll.
  • This shearing method also provides the same effects as those of the shearing using the punch and the die. In other words, the thin plate is fully sheared before the convex push-cutting blade of the die cutter penetrates through the thin plate and become fitted into the shearing recess of the anvil roll.
  • the convex push-cutting blade of the die cutter is thrust to a position corresponding to a depth in the thin plate which is equal to or greater than the thickness of the metal layer and equal to or less than the total thickness of the one or more non-metal layers.
  • an intermediate plate having at least one non-metal layer may be inserted between the die cutter and the thin plate. Based on using the intermediate plate in the above manner, the thin plate can be more reliably sheared by a pressing effect arising from plastic flow of the intermediate plate.
  • the convex push-cutting blade of the die cutter is thrust to a position corresponding to a depth in a combination of the intermediate plate and the thin plate which is equal to or greater than a total thickness of the metal layers of the thin plate and equal to or less than a total thickness of the one or more non-metal layers of the thin plate and the intermediate plate.
  • a press roll devoid of the convex push-cutting blade may be used.
  • the present invention provides a method of shearing a thin plate prepared by laminating one or more non-metal layers on one or respective ones of opposite surfaces of a metal layer.
