Embodiment Construction

[0219] Hereinafter, a hemming processing method and a hemming processing apparatus according to exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0220]

[0221] As shown in FIG. 1 , the hemming processing apparatus 10 according to the present embodiment is provided at an intermediate step of a production line 14 for assembling and processing a vehicle (workpiece) 12 in a so-called body-in-white state. The flange 17 of the wheel arch is an equipment for roll hemming. The wheel arch portion 16 is configured in a substantially circular arc shape of 180°. In a state before being processed by the hemming apparatus 10 , the flange 17 is configured in a shape bent inwardly by 90° from the end portion 16 a (see FIG. 6 ) of the wheel arch portion 16 .

[0222] The hemming processing apparatus 10 includes a moving die 18, which is in contact with the wheel arch 16 of the vehicle 12 (which constitutes a workpiece), a robot...

Abstract

The invention discloses an hemming working method and a hemming working apparatus. A moving die 18 is held by a robot 22 and made to approach a vehicle 12, and a positioning pin 62 is inserted into a positioning hole 65 of the vehicle 12. The moving die 18 is brought into a floating state of being displaceable relative to the vehicle 12 by reducing a force of the robot 22 for maintaining an attitude thereof. In a state of holding the moving die 18 by the robot 22, a surface 49a of the moving die 18 is brought into contact with the vehicle 12 by an adsorbing mechanism 58 including an adsorbing portion 67a of an elastic member provided to the moving die 18. The moving die 18 and the robot 22 are cut to be separated.

Description

technical field [0001] The present invention relates to a hemming processing method and hemming processing apparatus for bending an edge portion of a workpiece by using a processing roller. Background technique [0002] The edge parts of the hood, trunk, door, and wheel house of an automobile are hemmed by bending the flange raised from the edge part of the board to the inner side of the board. As such a hemming process, a roll hemming process can be performed in which a plate can be held in position on a mold and the flanges can be bent while being rolled onto the flanges at the ends of the plate. In roll hemming processing, due to the large bending angle, considering the accuracy of the bending, multiple stages of pre-bending (or pre-bending) and finishing bending (or regular hemming) are required. to process. [0003] As an apparatus for roll hemming processing, there has been proposed an apparatus for fixing a mold to a workpiece by providing clamps at various portions...
