However, this transmission method is not stable, and it cannot ensure whether there is stacking of bars during the transmission process, nor can it ensure that the bars enter the chamfering mechanism one by one for processing, thus affecting the chamfering efficiency and quality of the bars. Therefore, a conveying device for chamfered bars is proposed. Content of the Utility Model
