Description

Technical Field

[0001] The utility model relates to the technical field of pressure processing machinery, and in particular, to a multi-roller hemming tool. Background Art

[0002] The robot hemming process is that the robot moves the pressing wheel along the edge of the metal sheet at different angles to bend the sheet edge to reach the desired hemming angle. Its main types include flat hemming, pointed hemming, convex hemming, annular hemming, direct hemming and 180° hemming. The hemming process is divided into pre-hemming state, pre-packing state and final packing state.

[0003] The robot hemming system can adapt to different workpieces by making corresponding changes to the working program to adapt to different characteristics of the work. When facing different processing parts, it can smoothly move along the contour of the workpiece to perform rolling hemming motion. It overcomes the problems that it is difficult to achieve flexible production, high equipment maintenance cost and large working area with a set of flanging die process for hydraulic presses, and also solves the problem that the flanging force of the flanging machine is relatively small and the forming quality of the workpiece is not very good. It has a fast processing speed, high efficiency, and can ensure the consistency and accuracy of processing.

[0004] The existing Chinese patent with the patent number CN201010139014.3 and the patent name of a hemming wheel mechanism includes a bottom plate, a fixed seat fixed on the bottom plate, a rotating arm and a hemming wheel. One end of the rotating arm is hinged to the fixed seat, and the other end of the rotating arm is provided with the hemming wheel. An airbag with an air inlet is also installed on the bottom plate on the same side as the fixed seat, and the bottom of the airbag is connected to the other end of the rotating arm. This hemming wheel mechanism uses the airbag as a buffer and pressure regulating device, which can not only improve the buffering efficiency, but also achieve stepless controllability and reliable control of the pressure, and is suitable for various hemming occasions in the automotive industry.

[0005] Although the existing hemming mechanism can buffer the impact force, adjust the pressure and control it steplessly, its hemming wheel can only move along one angle. When performing flanging and hemming processing on workpieces with higher complexity, if the processing requirements need to be met, multiple groups need to be added to participate in the operation at the same time, resulting in poor flexibility in use, large occupied space and increased manufacturing cost. Therefore, the utility model provides a multi-roller hemming tool. Summary of the Utility Model
