Abstract
PURPOSE:To achieve high-precision hemming work through one operation by using a work pattern consisting of a prelminary bending pattern surface and a primary bending pattern surface in one body to hem a work composed of an inner panel and an outer panel. CONSTITUTION:To the lower pattern 1 of a hemming work device, a work 2 composed of an outer panel 2a and an inner panel 2b is fitted, and at its upper part, a work pattern 3 provided with a preliminary bending pattern surface 3a and a primary bending surface 3b successively is installed while energized by a spring 7 as shown by an arrow. The work pattern 3 is lowered to press the end part 2c of the outer panel 2a with the preliminary bending pattern surface 3a for preliminary bending work, and then the work pattern 3 is lowered to bring a slide cam 4 into slide contact with a driving cam 8. Consequently, the work pattern 3 is lowered while moving in the opposite direction to the arrow direction against a spring 7, and the primary bending pattern surface 3b performs the primary bending work of the end part 2c.
