Abstract: A peening device is provided with: peening impact pins that impact on a surface to be worked; a device main body that uses vibration to move the peening impact pins back and forth with respect to the surface to be worked; servo motors (22x, 22y) that adjust the inclination of the device main body with respect to the surface to be worked; laser displacement gauges (20A, 20B, 20C, 20D) that detect the device angle; and a vibration sensor (18) that detects the vibration state of the device main body. Furthermore, a control device (40) for the peening device controls the servo motors (22x, 22y) such that the vibration state detected by the vibration sensor (18) is a predetermined vibration state. Thus, the peening device carries out excellent peening by conforming to the surface to be worked, the shape of which changes from moment to moment because of the peening.

Abstract: A hot press-forming method includes a forming step that clamps a steel sheet heated to a temperature not less than an austenite transformation temperature and press-forms the steel sheet into a desired shape by causing a forming concave of a die and a convex of a punch to be close to each other. A formed portion has side and top portions that merge. The side portion rises up from an inner circumferential edge of a flange portion having been clamped by the die and the blank holder. A cooling step cools a region of the steel sheet after the heating step has been completed and before the forming step is completed. The particular region is along an inter-edge area formed between an opening circumferential edge of the forming concave and a top circumferential edge of the forming convex before the forming step is completed.

Abstract: A forming tool stamps sheet metal blanks into a desired shape. A contoured surface is defined for the forming tool so that respective portions of the metal blank flow over the contoured surface during forming. An intrinsic material flow pattern resulting from the contoured surface is compared to a desired flow in order to identify regions of the contoured surface having an insufficient flow that creates areas in the formed metal blank receiving less than a desired amount of metal. A surface microtexture is applied onto the contoured surface in a pattern selected to increase metal flow along the identified regions by providing a coefficient of friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.
