s4: the steel bottle flows and is stored, the turnover plate rotary pressing mechanism returns to the original position, the main machine is rotated and closed, the thick cutter is drawn out, the clamping jaw on the main shaft is loosened, and the bottle blank is taken out and sent to the next bottom pressing procedure.
9. The steel cylinder bottom thickening process of claim 8,
the thickness of the thin cutter is 9-11mm smaller than that of the thick cutter, and preferably, in the invention, the thickness of the thin cutter is 10mm smaller than that of the thick cutter.
10. The steel cylinder bottom thickening process of claim 8,
the rotation speed of the steel pipe in the S1 is 650-.
