Abstract
In a manufacturing method of a thickness-varied metal plate, first, a cut plate is manufactured by cutting a metal plate having a constant plate thickness into a predetermined shape. Next, the thickness-varied metal plate is manufactured by rolling the cut plate using a processing machine including a pair of work rolls. Here, a radius of one of the pair of work rolls is varied in a circumferential direction and an axial direction. Accordingly, the thickness-varied metal plate manufactured by rolling the cut plate using the processing machine has a plate thickness varied in two different directions orthogonal to a plate thickness direction.

A manufacturing method of a thickness-varied metal plate, the manufacturing method comprising:
- manufacturing a cut plate by cutting a metal plate into a predetermined shape;
- and
- manufacturing a thickness-varied metal plate of which a plate thickness is varied in two different directions orthogonal to a plate thickness direction by processing the cut plate through at least one of rolling and forging, using a processing machine including a first work roll and a second work roll of which a radius is varied in a circumferential direction and an axial direction of a rotational axis.
A manufacturing method of a thickness-varied metal plate, the manufacturing method comprising:
- manufacturing a cut plate by cutting a metal plate into a predetermined shape;
- and
- manufacturing a thickness-varied metal plate of which a plate thickness is varied in two different directions orthogonal to a plate thickness direction by sequentially processing the cut plate through at least one of rolling and forging, using a first processing machine including a first work roll and a second work roll of which a radius is varied in a circumferential direction or an axial direction of a rotational axis, and a second processing machine including a pair of work rolls that are different in shape from the first work roll and the second work roll of the first processing machine.
