ROLLER HEMMING PROCESSING DEVICE AND ROLLER HEMMING PROCESSING METHOD

Title:

ROLLER HEMMING PROCESSING DEVICE AND ROLLER HEMMING PROCESSING METHOD

Document Type and Number:

WIPO Patent Application WO/2014/174874

Kind Code:

A1

Abstract:

A panel that forms a work object is inserted onto a die face (1a) of a hemming die (1) and pre-hemming (preliminary bending) and hemming (main bending) processes are carried out with a hemming roller held by a robot. A nesting mechanism (6) for positioning the panel is provided on a side wall part (1b) of the hemming die (1). The nesting mechanism (6) has a movable nesting block (8), which has a nesting claw part (8b) at the tip thereof, held by a holder (7), and the nesting block (8) is elastically supported retractably in the vertical direction (direction of arrow P1) and slidably (tiltably) displaceable in the direction of arrow P2. Thus, interference of the hemming roller and nesting mechanism (6) has no bad effects on hemming process quality.
