Description

Technical Field

[0001] This utility model relates to the field of mechanical automation, and in particular to an adjustable automatic flanging machine. Background Technology

[0002] Currently, the workpiece fixing fixtures of flanging machines are generally customized according to the size and shape of the workpiece, and can only fix workpieces of a specified size and shape. When it is necessary to fix workpieces of other sizes and shapes, other fixing fixtures need to be customized, which is costly and not very flexible in use. In addition, after the workpiece is fixed by the workpiece fixing fixture, two rollers that move in opposite directions are set on the inner and outer sides of the workpiece side wall. Flanging is completed by the relative movement of the two rollers and the customized shape of the rollers. The two rollers only move in opposite directions, and the relative motion trajectory is relatively simple, so there are few flanging shapes that can be processed. Utility Model Content
