Abstract

The invention belongs to the technical field of automobile metal plate connecting tools, and particularly relates to a door opening edge rolling tool. Connection between an outer plate and an inner plate of an automobile side wall is achieved through an edge rolling tool, and the whole tool is installed on an automatic mechanical arm, and is provided with an edge rolling module, a force applying module, a constant force module, a force direction balancing module and the like, and the stress application requirement, the gravity center keeping requirement, the edge rolling effect uniformity requirement and the fluctuation edge rolling effect requirement when the innovative edge rolling technology is applied to automobile side wall door opening metal plate connection can be completely met. Compared with a traditional welding and riveting process, welding spots and rivets do not need to be additionally arranged on an A column, the size of the A column is reduced, the visual field of a driver is extended, safe driving is facilitated, meanwhile, the material consumption is reduced, the equipment input cost is reduced, and the cost input of a side wall door opening edge rolling process is reduced; and compared with an existing edge covering process, the edge rolling tool has the technical advantages of being small in occupied area, low in cost and high in metal plate connecting strength.

Description

technical field [0001] The invention belongs to the technical field of connecting tools for automobile sheet parts, and in particular relates to a hemming head tool for door openings. Background technique [0002] The connection process between door openings and sheet metal parts in traditional automobile manufacturing is as follows: In traditional automobile manufacturing, the door opening area is mainly completed by welding and riveting. Since welding and riveting will increase solder joints and rivets on the A-pillar, it will increase A. The volume of the column brings the disadvantages of large blind area and large volume of the A-pillar. [0003] At the same time, with the advancement of automobile processing technology, automobile production has been developing in the direction of automation and efficiency. In the automatic production workshop of automobiles, corresponding automatic processing tools need to be added for the welding process and rivet process, and the u...
