Problems solved by technology

Because the counter pressure is omitted here, the hemming quality is not always satisfactory
In addition, this relatively involves a device dedicated to only one type of airframe in each case, which makes it problematic to use this device in a production facility where different types of airframes are produced

Embodiment Construction

[0036] FIG. 1 shows a protective strip 1 within a frame 2 . As will be appreciated, the protective strip 1 follows the trajectory of the wheel section. Its inner side 1i, visible in the figure, exhibits a contour that is a negative replication of the desired body contour on the wheel arches. The outer profile is usually not smooth, but is often provided with different facets and vertical structures in order to obtain a certain aesthetic effect and / or a smooth transition to adjacent body parts. The profile must not be destroyed.

[0037] The frame 2 comprises a number of markers in the form of positioning pins 4 which engage with corresponding holes in the body so as to positively fix the protective strip 1 relative to the body. Mechanical clamps 5 hold the frame 2 so that the protective strip 1 is clamped to the body.

[0038] The outer side of the protective strip 1 is smooth and forms the rolling surface 1a for the counter-pressure roller of the hemming head (FIG. 3).

Abstract

The present invention provides a rolling apparatus for the rolling and press of the edge of the parts (20, 25), the apparatus includes: a rolling heads (11,12,13); b, the first roller (14a, 14b, 14c), is mounted by the rolling heads (11, 12, 13) and rolled on the edge during the rolling and pressing time; c, the second roller (15a, 15b, 15c) is mounted by the roller heads (11, 12, 13) and forming counterpressure roller used for the first roller (14a, 14b, 14c); characterized in that the rolling device includes a stable protection structure (1, 3), it is fastening or fasten on the parts (20, 25), and forming a rolling surface or a supporting rolling surface used for one of the roller (15a, 15b, 15c).

Description

technical field [0001] The present invention relates to a flanging device for rolling and flanging the edge of a component or other workpiece along the flanging edge, and to a flanging method. The hemming device is preferably made as a hemming device for producing a hem connection. The parts are preferably raw or already assembled body parts. The invention is particularly advantageous if the body part forms a visible area in a subsequent finished product, preferably a vehicle, such as an outer part of the body. [0002] The invention preferably relates to an apparatus for flanging the edge of a first body part, preferably forming the outside of the body, wherein the edge of a second body part (for example forming the inside of the body) is located at the first body part. In the hemming groove of a body part. The device comprises a crimping head having at least one counter pressure roller and preferably at least two pressure rollers for continuously turning the edge of the f...
