Laser welding head for welding device has sheet pressing rollers mounted on common eccentric bearing shaft joined to pressing device so as to be rotatable about central axis

摘要

The device has a contact pressure device with at least two pressing rollers that are each pressed onto one side of the weld joint and rolled along a sheet by a pressing device. The rollers are mounted on a common eccentric bearing shaft joined to the pressing device so as to be rotatable about a central axis. The rollers are mounted on mutually offset eccentric shaft sections (11,12).
