Definitions

  • a cylindrically formed product which is manufactured by performing cylinder forming in which a metal material is formed by performing bending forming is used for a food container, a medical device, a metal container, an equipment part and so forth.
  • cylinder forming a cylindrically formed product which is manufactured by performing cylinder forming in which a metal material is formed by performing bending forming
  • a three-piece can which consists of an end, a body and a bottom end a cylinder product formed by performing cylinder forming is used for the body.
  • spring back occurs due to elastic recovery when a metal material (a metal sheet) is subjected to cylinder forming and then unloaded, which results in a change in the shape of the cylinder. Therefore, when cylinder forming is performed, it is necessary to determine the conditions under which cylinder forming is performed in consideration of spring back in advance.
  • a thickness reduction causes an increase in a spring back angle, which makes it impossible to achieve a specified shape of a cylinder, that is, a specified lapping width.
  • a spring back angle is defined in terms of an amount of change in a bending angle from the loaded state to the unloaded state in bending forming.
  • a lapping width is, as illustrated in Fig.
  • a lapping width has a value of 0 in the case where both edges butt each other, a positive value in the case where both edges are separated by a gap and a negative value in the case where both edges overlap each other.
  • a metal material can be designed so that a specified shape of a cylinder (lapping width) can be obtained even if the thickness of the material is reduced, it is not necessary to readjust forming conditions or remodel a forming apparatus. That is to say, it is necessary to design a metal material with which a spring back angle equivalent to that of a metal material before the thickness is changed can be obtained even after the thickness has been changed.
  • Non Patent Literature 2 reports that, the theoretical equation (2) does not necessarily correctly replicate experimental findings. Moreover, although Non Patent Literature 2 proposes an empirical equation regarding a stainless steel sheet, since the target metal material is limited to a stainless steel sheet, it cannot be said that it is suitable for a wide variety of metal materials and there is a problem left from the viewpoint of versatility.
  • the present invention has been completed in view of the situation described above.
  • the inventors found a new method for calculating a spring back angle which occurs when metal materials having a wide variety of mechanical properties and thicknesses are formed by performing cylinder forming, and an object of the present invention is to provide a method for designing a metal material having a material quality (mechanical properties) with which a specified spring back angle can be achieved by using this calculating method and a formed product which is manufactured by performing cylinder forming from the metal material which is designed by using the designing method.
  • a metal material with which a spring back angle can be controlled to a specified value can be easily designed and there is a large contribution to the improvement of productivity and the reduction of cost of a cylinder forming process.
  • a formed product in the case where thickness is changed from t 1 to t 2 , a formed product can be obtained without change in lapping width after cylinder forming has been performed, if a metal material having mechanical properties with which a spring back angle equivalent to that of a metal material having a thickness of t 1 is achieved is used.
  • the present inventors conducted investigations regarding what kinds of factors among the various factors have an influence on the spring back angle, and, as a result, confirmed that such kinds of factors are a bending angle, a radius of curvature of bending, a thickness, a yield strength and a Young's modulus.
  • equation (7) is derived by substituting equation (6) into equation (5) described above.
  • n (work hardening coefficient) 0, equation (2) described above is derived from equation (7).
  • n 0 in an actual metal material and the value of n varies depending on the kind of metal material.
  • Non Patent Literature 2 it was found that there is a correlation between ⁇ / ⁇ and (YP ⁇ r)/(E ⁇ t), and equation (8) is derived.
  • the target metal material is limited to a stainless steel sheet, the range of a factor with which ⁇ / ⁇ is determined is narrow (0 ⁇ (YP ⁇ r)/(E ⁇ t) ⁇ 0.11), which results in a lack of versatility.
  • ⁇ / ⁇ 1.9 YP ⁇ r / E ⁇ t 0.62
  • the present inventors observed a spring back angle by actually performing bending forming with a wide variety of metal materials (an aluminum sheet, a copper sheet, a stainless steel sheet and a steel sheet) and thickness conditions, where the radius of curvature of bending was in the range of 5 mm or more, the bending angle was in the range of 90 degrees or more and 180 degrees or less and the thickness was in the range of 0.1 mm or more and 2.0 mm or less. This is because these ranges can sufficiently satisfy the requirements for practical use of these materials in the fields of a food container, a medical device, a metal container, an equipment part and so forth, which means that there is versatility.
  • ⁇ denotes the observed data in Non Patent Literature 2 and dotted lines denote equation (8) and theoretical equation (2).
  • a spring back angle ⁇ before a thickness is changed is observed.
  • a test piece having arbitrary dimensions is subjected to bending forming under the conditions of, for example, a radius of curvature of bending of 12.7 mm and a bending angle of 180 degrees.
  • a bending angle ⁇ ' of the test piece in the unloaded state is observed and a spring back angle ⁇ is calculated by using equation (3) described above. This procedure may be omitted in the case where a spring back angle ⁇ exists as stored data.
  • a metal material having the mechanical properties described above may be selected from a database of a metal material, or a new material may be designed in accordance with the YP and E as indexes in the case where the database cannot be found.
  • a metal material is subjected to bending forming and a spring back angle is observed before the mechanical properties of the metal material are changed.
  • a thickness t is calculated by using equation (1) using the spring back angle described above, a yield strength YP and a Young's modulus E which are specified in advance and the conditions of bending forming (a radius of curvature of bending and a bending angle).
  • the lapping width which is the same as that of the metal material before the mechanical properties of the metal material is changed can be achieved by forming the metal material having this thickness and these mechanical properties by performing cylinder forming.
  • a specified lapping width can be achieved after cylinder forming has been performed, firstly by making the spring back angle of the metal material clear before the change, and then, by determining the properties of the metal material one after another under conditions in which equation (1) is satisfied.
  • the mean value of the lapping width after cylinder forming had been performed on a steel sheet (No. 2) having YP 300 MPa was -10.5 mm, which means that a lapping width equivalent to that of the metal material before the thickness was reduced was achieved in consideration of the variability of lapping width.
  • the mean value of the lapping width after cylinder forming had been performed on a steel sheet (No. 3) having YP 362 MPa was +5.0 mm, which means that a lapping width equivalent to that of the metal material before the thickness was reduced was not achieved.
  • the mean value of the lapping width after cylinder forming had been performed on a steel sheet (No. 2) having E 231000 MPa was -10.5 mm, which means that the lapping width equivalent to that of the metal material before the thickness was reduced was achieved in consideration of the variability of lapping width.
  • the mean value of the lapping width after cylinder forming had been performed on a steel sheet (No. 3) having E 214000 MPa was -2.4 mm, which means that a lapping width equivalent to that of the metal material before the thickness was reduced was not achieved.
