[0024] The above-mentioned edge trimming device for sheet metal machining firstly places the sheet metal part to be processed on the base plate 1, ensures that the edges of the sheet metal part are aligned with the inner side of the machine shell 6, and the design of the base plate 1 keeps the sheet metal part stable during the trimming process and prevents the sheet metal part from moving or tilting, the sheet metal part can be pushed in the direction of the machine shell 6 by selecting a manual or mechanical arm mode, at this time, the edges of the sheet metal part will gradually approach the upper polishing assembly 7 and the lower polishing assembly 8;

[0025] When the edges of the sheet metal part contact the upper polishing assembly 7 and the lower polishing assembly 8, the polishing assembly will start to contact the edges of the sheet metal part and perform preliminary polishing, this process is suitable for straight-edged sheet metal parts, the rotation of the polishing assembly will provide the necessary grinding force, so that the edges of the sheet metal part are effectively trimmed, and in the polishing process of the straight-edged sheet metal part, the user only needs to keep the sheet metal part in contact with the vertical upper polishing assembly 7 and lower polishing assembly 8, so as to complete the edge trimming operation;

[0026] When the arc-shaped edge of the sheet metal part contacts the upper polishing assembly 7 and the lower polishing assembly 8, the user continues to push the sheet metal part, causing the upper polishing assembly 7 and the lower polishing assembly 8 to flip, and the flipping action is linked. In the flipped state, the upper polishing assembly 7 and the lower polishing assembly 8 will closely fit the arc-shaped edge of the sheet metal part, and through the movement of the polishing belt 708, effective grinding force is provided to quickly trim the edge. This process can adapt to various sizes and shapes of arc-shaped edges, ensuring uniform and required trimming effect.
