Auxiliary guide mechanism for reinforcing steel bar machining and reinforcing steel bar straightening device

The utility model discloses an auxiliary guide mechanism for reinforcing steel bar processing and a reinforcing steel bar straightening device, which are used for enabling a reinforcing steel bar to pass through and limiting the swing range of the reinforcing steel bar when the reinforcing steel bar is processed, and comprise a support frame, a guide frame and a dust blocking component, the radial size of the guide frame is gradually reduced in the direction from an inlet to an outlet of a steel bar, the dust blocking assembly comprises a plurality of dust blocking plates, the dust blocking plates are sequentially spliced in the circumferential direction of the guide frame and fixedly connected to form a dust blocking frame arranged on the periphery of the guide frame in a surrounding mode, and the periphery of the guide frame is separated from the outside through the dust blocking frame. And the dust blocking frame body is used for blocking rust powder generated in the guide frame and enabling the rust powde
