Title:

PLATE-LIKE WORK FORMING DEVICE, AND PLATE-LIKE WORK FORMING METHOD

Document Type and Number:

Japanese Patent JP2003025025

Kind Code:

A

Abstract:

To form a plate-like work into a compound curved surface of high accuracy with a simple structure.

When forming the plate-like work 63t into a compound-curved surface of an arbitrary shape by performing the shot-peening, the plat-like work 63t is supported in a rotatable manner around the Y-axis which is the shot direction, in a positionally adjustable manner in the Z-axis direction orthogonal to the Y-axis, and in a movable manner at an arbitrary speed in the X-axis direction orthogonal to the Y-axis and the Z-axis. The plate-like work 63t is divided into a plurality of working areas TP1-TP6, the shot-peening is performed while moving the plate-like work 63t in the X-axis direction at the predetermined speed so that the center line CL1-CL6 of the respective working areas TP1-TP6 are coincident with the center of projection of shot materials. When the moving speed of the plate-like work 63t is low, the peening strength is increased, and a large curvature is given. When the moving speed is high, the peening strength is decreased, and a small curvature is given, and the plate- like work 63t can be formed in a compound-curved surface.
