Problems solved by technology

In addition, since the main bending is performed using a large-diameter main bending roller, if there is an obstacle on the flange side, for example, an inner panel or the like protrudes above the peripheral edge of the workpiece to be hemmed. In some cases, the main bending rollers and obstacles tend to interfere, and there are cases where the main bending cannot be performed satisfactorily.

Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016] figure 1 It is a figure which shows the schematic structure of the roll hemming apparatus of a typical embodiment, and the roll hemming apparatus 1 to which the roll hemming method is applied. The roller hemming device 1 has a processing table 30 , a processing roller mechanism 10 , and a robot arm 40 .

[0017] The table 30 for processing has the support base 31 provided on the ground, and the table part 32 supported by the support base 31. As shown in FIG. A workpiece W is placed on the table portion 32 . The workpiece W is, for example, an automobile door panel or the like, and is composed of an outer panel W1 and an inner panel W2. The outer panel W1 has a flange WF bent at approximately 90° at the remaining peripheral portion of the portion (main body) where the inner panel W2 is disposed at the center. The inner panel W2 has a protruding portion W21 ove...

Abstract

A roller hemming device includes a large diameter roller having a large tapered surface and a small diameter roller having a small cylindrical surface. The small diameter roller is coaxially disposed with the large diameter roller. The small diameter roller and the large diameter roller enable to relatively move in an axial direction. The outer diameter of the small cylindrical surface is smaller than the minimum outer diameter of the large tapered surface.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201380024168.X, the application date is May 8, 2013, and the invention title is "roller hemming device and roller hemming method". technical field [0002] The invention relates to a roller hemming device and a roller hemming method. Background technique [0003] Patent Document 1 discloses an apparatus including: a roller for pre-bending having a tapered surface; and a cylindrical main-bending roller spline-fitted to the outer periphery of the roller for pre-bending. The rollers for main bending move relatively coaxially with respect to the rollers for preliminary bending. The preliminary bending of the peripheral portion of the workpiece is performed by bringing the tapered surface of the preliminary bending roller into contact with the flange in a state where the preliminary bending roller protrudes from the main bending roller. Then, in the state where the...
