The use of the push plate can effectively push the sheet metal smoothly to avoid production delays and damage caused by the workpiece being stuck. The push plate can evenly apply force and push the sheet metal to avoid additional stress concentration on the sheet metal during the pushing process, thereby protecting the surface quality and shape integrity of the sheet metal.
