At present, conventional round bar cutting devices usually use a grinder with a single grinding wheel to cut a single long round bar in sections. The cutting efficiency is low, and it is difficult to control the uniformity of the cutting length. The control requirements for cutting accuracy are relatively high, which increases the cutting cost. Some cutting equipment that can cut multiple long round bars in multiple sections are usually large in size, complex in structure, and high in cost. Summary of the invention
