Leading Tier One automotive pressings and components supplier Stadco has chosen a DV Automation robotic hemming cell for joining closure parts at its plant in Coventry. Stadco is using the cell to hem bonnets and tailgates for its UK customer base.

Halesowen-based DV Automation developed the cell using the latest 3D robot simulation software packages, which significantly reduced the programming and commissioning process.

The compact cell comprises a single hemming station positioned around a KUKA robot which is equipped with a roller hemming head. The robot guides the hemming head around the part to form the hem joint, ensuring the inner and outer panels of the component are not only closed to form a safety edge but are also finished to a high standard.

The versatile cell has also been specially designed to handle a variety of model variants and, in addition, it can be easily expanded at a later date to perform other tasks as the robot has been fitted with a tool changing system. Stadco is considering extending the cell’s capabilities in the future so it can operate dispensing equipment for sealants.

Minor changes and modifications to panel hemming conditions can be quickly accommodated while different hemming head and roller configurations for all common types of hemmed joint such as euro hem, soft hem and styling edge, are also possible.

“Although this particular cell is being used for spares production, robot hemming is being utilised more and more in mainstream automotive production. The trend for manufacturers to have several model variants all based on one chassis platform means this process is more attractive due to its high flexibility and cost-effectiveness,” commented Mark Schlanker, DV Automation’s business manager.

“Advances in technology mean today’s industrial robots are not only extremely efficient, reliable and more affordable, but they also deliver lower operating and maintenance costs. A single robot hem system, such as the one being used by Stadco, can be configured to produce a number of model variants and can be adapted at a later date for a range of other processes,” he added.
