EDAG Roller hemming EDHS 180°
Our Roller hemming systems are a cost-efficient alternative to conventional pressing because of their lower investment and maintenance costs and their shorter developement and completion.

The EDHS 180° Rollerhemming tool is working with four pairs of rollers. One roller is doing the forming, the other one is absorbing the forces so as not to burden the robot. Contrary to common roller hemming, no hemming bed or die is necessary.

This roller hemming tool is used e.g. for hemming the flanges of a sun-roof in 4 steps for steel and 5 steps for aluminium.

Flying Roller hemming

A perfect application for EDHS 180° is the so called flying roller hemming. The part is handed over by a robot to the stationary EDHS 180°. The robot picks up the part, applies adhesive, loads the reinforcement, performs the hemming, and releases the assembly. For the above described process, a space of 25m² is sufficient. The cycle time for this process can be 120 sec.

Stationary Roller hemming

The sun-roof-flange can also be manufactured conventionally. The part is fixed to a stationary device and the flange is closed using a robot with the roller hemming tool EDHS 180°.

Flexibility

According to this the EDAG system offers the best possible flexibility. The stationary hemming tool EDHS 180° is rigidly mounted. The intelligent surface protection device either caters for the different part geometries or can be exchanged for new parts.

Advantages

When model changing only the surface protection device (hemming frame) and program needs changing. Due to flexibility many different models can be produced in one single cell.

Application areas

  • Roller hemming of (for e.g.) a sun-roof-flange in 
    – 4 Steps for Steel parts
    – 5 Steps for Aluminium parts 

Features

» Feed averages between 100 mm/sec to 450 mm/sec
» Availability together with robot >99,8%
» Standardized system
» Lowest maintenance
» Part quality can be influenced by adjusting the robot program
» The radius is established “just“ with the hemming tool and can be adjusted
» On the robot moving or stationary hemming tool
» Hemming of Aluminium parts is possible (e.g. Rolls Royce SHD)
» Revolutionary low investment costs, especially when applying multiple types
