Hemming method using complex roll hemming device for small quantity batch production

The present invention relates to a hemming method using a complex roll hemming device for multi-quantity small quantity production, and more particularly, to a simple structure to support the outer panel firmly, and to press the inner panel laminated on the upper side at the same time The present invention relates to a technology for suppressing a defective rate during a hemming operation by clamping along both circumferences.

In Korea, the press market hemming method is mainly used since it maintains the automotive market centered on mass production system of props, and it is not suitable to apply roll hemming method.

Since the start of automobiles has also been converted to a multi-product small-scale production system, mixed-flow production for various product groups has become very important, and researches using roll hemming methods have been conducted to cope with the multi-product small-scale production system and secure the efficiency of mixed production. Since the reliability is not secured, it is not directly applied to the field of business and is applied to only a few parts.

On the other hand, in the overseas market, the hemming method using the press method was mainly used. However, at the time of introduction of the small quantity batch production system mentioned above, many automobile related industries are shifting to the roll hemming system. In Japan and Germany, most of the transitions to the roll hemming system have been made, and technology is accumulated.

Overseas roll hemming equipment is still adopting clamping method using clamping, and instead, the process conditions are optimized based on existing know-how. However, although the process reliability of the roll hemming method is secured, the productivity and production efficiency are still somewhat lower than that of the press method, and in the case of overseas related markets, as in the domestic market, a direct study to cope with the productivity and mixed production of roll hemming Development is not ongoing.
