[0037] Start the No. 1 hydraulic cylinder 10 to push the support plate 8 upward, so that the top surface of the support plate 8 is close to or flush with the top surface of the differential chain line 2. When the circular saw blade is transported to the hole opening position, it will be intercepted and positioned by the rear positioning plate 12. Then the No. 1 hydraulic cylinder 10 pushes the support plate 8 to continue to move upward, lifting the circular saw blade blank. At this time, the front positioning plate 11 extends to intercept the subsequent circular saw blade blank;

[0040] After the processing is completed, the No. 1 hydraulic cylinder 10 is started to pull the support plate 8 downward, so that the circular saw blade moves downward, and the differential chain line 2 is started. When the circular saw blade moves downward to the position of the differential chain line 2, it will be supported by the differential chain line 2, and the support plate 8 continues to move downward to separate the rear positioning plate 12 from the circular saw blade. The differential chain line 2 automatically transports and unloads the circular saw blade, and at the same time, the circular saw blade blank on the front side moves to the hole opening position. This cycle can be repeated to achieve continuous circular saw blade blank hole opening processing;
