Description

Technical Field

[0001] The present invention relates to the technical field of bending processing, and in particular to a bending processing device and method. Background Art

[0002] In the traditional folding process, the staff is required to manually feed the stainless steel plate into the folding machine. Since the stainless steel plate needs to be folded three times to form the hemming, it is equivalent to having three folds on each side of the stainless steel plate. However, since the traditional folding machine can only bend the stainless steel plate once each time, after completing the first bend, the staff needs to feed the stainless steel plate again so that the second fold of the stainless steel plate is located under the bending knife; after completing the second bend, the staff needs to feed the stainless steel plate again so that the third fold of the stainless steel plate is located under the bending knife; after completing the third bend, the staff needs to rotate the stainless steel plate 90 degrees and fold the hemming on the other side again. However, the above operation process is particularly cumbersome, not only with low production efficiency, but also high production cost.

[0003] The publication number is CN115502250B. The automatic bending device and method for stainless steel cabinet plates include a frame, a feeding device, an edge processing device, a discharging device and a conveying device. The edge processing device includes a first bending mechanism, a second bending mechanism and a third bending mechanism. When the side of the stainless steel plate enters the edge processing station, the first bending mechanism, the second bending mechanism and the third bending mechanism bend the stainless steel plate three times in sequence to form an edge. The conveying device includes a conveying assembly, a lifting conveying mechanism, a self-rotating conveying mechanism, a longitudinal conveying mechanism and a transverse conveying mechanism. The automatic bending device of the present invention can not only automatically realize multiple folding of the stainless steel plate to form an edge, but also automatically realize edge processing of multiple sides of the stainless steel plate, which makes the automatic bending device of the present invention more automated, effectively improves production efficiency, and further reduces production costs.

[0004] The above-mentioned technical components can effectively realize multiple folding of stainless steel plates, but the bending processing templates they can cope with are relatively single. When the template needs to be replaced, the equipment needs to be shut down and the template needs to be disassembled and replaced. The work efficiency is slow and it is not convenient to improve the bending function of the equipment, so it needs to be improved. Summary of the invention
