Title:
MANUFACTURING METHOD FOR METAL PLATE OF DIFFERENT THICKNESS AND PRESSED COMPONENT MANUFACTURING METHOD AND PROCESSING MACHINE
Document Type and Number:
Japanese Patent JP2018099699
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a degree in freedom in setting a change in plate thickness of a metal plate of different thickness such as steel plate of different thickness.SOLUTION: According to a manufacturing method of a metal plate of different thickness, according to the present invention, in a cutting process, a steel plate (metal plate) of constant plate-thickness is cut into a predetermined shape and a blank material B (a sheet to be rolled) is manufactured. Subsequently, in the rolling process, the blank material B is rolled by a rolling machine 10 with a pair of work rolls 12 and a steel plate TB1 (metal plate of different thickness) is thereby manufactured. Here, the pair of work rolls 12 are changed in radius in a circular direction and in an axial direction. Thus, a steel plate TB1 of different thickness, manufactured by rolling the blank material B by means of the rolling machine 10, is changed in plate thickness in two different directions orthogonal to a plate thickness direction.SELECTED DRAWING: Figure 1
