(4) And (5) repeating the step (3) until the four side edges of the stainless steel plate are all subjected to edge covering processing, and then carrying the processed stainless steel plate to a discharging device by the carrying device.
10. The automatic bending method of stainless steel cabinet board according to claim 9, wherein in step (2), the bending step is:
(2-1) moving the first pressing block, the second pressing block and the third pressing block downwards so as to tightly press the stainless steel plate on the first bending knife, the second bending knife and the third bending knife;
(2-2) the first bending knife moves upwards, the first bending part on the first bending knife enables the side edge of the stainless steel plate to be bent upwards, when the first bending part is matched with the right-angle groove in the first pressing block, the first bending of the side edge of the stainless steel plate is completed, and a first folded edge is formed on the stainless steel plate; then, the first pressing block and the first bending knife reset respectively;
(2-3) moving the second bending knife upwards, wherein a second bending part on the second bending knife enables the side edge of the stainless steel plate to be bent upwards, and the side edge comprises the first folded edge; after the first folded edge is contacted with the side face of the second pressing block, a second folded edge is formed on the stainless steel plate; then, the second pressing block and the second bending knife reset respectively;
(2-4) moving the third bending knife upwards, wherein a third bending part on the third bending knife promotes the upward folding of the side edge of the stainless steel plate, which comprises the first folding edge and the second folding edge; when the side edge of the stainless steel plate is turned over by 90 degrees, a third folded edge is formed on the stainless steel plate; then, the third bending knife resets respectively;
(2-5) the second pressing block moves downwards, and a bending groove in the second pressing block is in contact with a second folded edge on the stainless steel plate and enables the second folded edge to be folded downwards until the second folded edge and the third folded edge form an included angle of 90 degrees;
(2-6) the third pressing block moves upwards, and a fourth bending part on the third pressing block is matched with the bending groove in the second pressing block, so that one side, far away from the second folded edge, in the first folded edge is bent towards the third folded edge.
