Title:
METHOD FOR MANUFACTURING PRESS MOLDING
Document Type and Number:
Japanese Patent JP2023123186
Kind Code:
A
Abstract:
To efficiently alleviate a temperature drop of a heated workpiece while the heated workpiece is conveyed to a press molding position.SOLUTION: A method for manufacturing a press molding includes a heating step of simultaneously heating at least two plate-like workpieces W1 and W2 by a heating device 14, a conveyance step of conveying the two heated workpieces W1 and W2 to a press machine 20, and a press step of processing the two heated workpieces W1 and W2 by the press machine 20. The conveyance step holds the two heated workpieces W1 and W2 in a state of facing each other; in at least a part of the end of the first heated workpiece W1 out of the two heated workpieces, the end region including the end of the first heated workpiece has a shape bent toward the second heated workpiece W2; and a distance D in the opposite direction between the end of the first heated workpiece W1 and the second heated workpiece W2 is smaller than a maximum interval Dmax in the opposite direction of the two heated workpieces.SELECTED DRAWING: Figure 1
