Abstract (en)
[origin: EP0206235A2] The invention relates to a method for upsetting bar-shaped material, such as steel rods, the bar-shaped material being upset against a movable upsetting track, and to a device for upsetting bar-shaped material with at least one movable upsetting punch, one upsetting track and a holding device between the upsetting punch and the upsetting track and, if required, a device for heating the material, in which the upsetting track can be moved with adjustable speed. By virtue of the invention, it is possible, in one upsetting operation, for example in the case of steel rods, to upset a length of material similar to that in electroupsetting. <IMAGE>
