Problems solved by technology

Furthermore, the drives of the prior art have the problem that the workpiece is generally not prevented from performing an undesired movement or an undesired continuous movement in the opposite direction (to the feed movement) without increasing complexity
Therefore, positioning accuracy during shifting is disadvantageously compromised

Abstract

The invention relates to a drive device for driving a tool slide in a hemming system, the drive device comprising a slide plate connected directly or indirectly to the tool slide and a drive shaft rotating about an axis of rotation. The rotational movement of the drive shaft can be converted by means of the cam into a linear movement of the slide, which travels in the forward direction.

Description

Drives for driving tool slides in hemming systems technical field The invention relates to a drive device for driving a tool slide in a feed direction in a hemming installation and to a method for driving the tool slide. Background technique Such drives are used, for example, in industrial production plants to form semi-finished products or components. Such drives of the type in question are found in particular in hemming devices in which metal sheets are usually hemmed and a driven tool slide deforms the workpiece. In this type of bending, the precision with which the tool slide is driven is often a determining factor for the quality of the hemming operation. The part being hemmed is usually the part that has an outer cladding or sheath. Its appearance, which is influenced by the quality of the flanging operation, is therefore often the reason for demanding the highest possible criteria with respect to the positioning accuracy or positioning reliability of the tool slid...
