The invention discloses a bending machine of bending and spiraling a rebar. The bending machine of bending and spiraling the rebar comprises a rack and a main machine plate, and further comprises a material receiving frame. A traction straightening mechanism and a bending mechanism are installed on the main machine plate. The material receiving frame comprises a fixed material receiving frame and an auxiliary adjustable material receiving frame. The fixed material receiving frame is a cylinder rod which is fixed on the main machine plate in a protruding mode. The auxiliary adjustable material receiving frame is a cylinder rod which is arranged parallel to the fixed material receiving frame in the protruding mode, and is fixed on the main machine plate in an adjustable mode. The fixed material receiving frame and the auxiliary adjustable material receiving frame are supported on the inner side of an arc of the rebar which is bent to be spiral in a spaced mode. A material stop bar is arranged between the fixed material receiving frame and the auxiliary adjustable material receiving frame. The bending machine of bending and spiraling the rebar has the advantages of being simple and compact in structure, reducing whole weight, and reducing cost. Due to the fact that the material receiving frame comprises the fixed material receiving frame and the auxiliary adjustable material receiving frame, load bearing strength of supporting a spiral rebar is high, deformation of the spiral rebar is small, and quality of the spiral rebar is improved. The material receiving frame is simple in structure, and low in manufacturing cost.
Description
technical field [0001] The invention relates to processing equipment for bending steel bars into spiral steel bars, in particular to a round bending machine for bending spiral steel bars. Background technique [0002] The round bending machine of spiral steel bar is a spiral steel bar that continuously bends the steel bar into a disc with a specified diameter. The structure of the bending machine of the prior art spiral steel bar includes: a frame; a box body arranged on the frame; a main board is supported on the box body; a traction mechanism, a straightening mechanism, a rounding mechanism and Receiver. The power driving devices of the traction mechanism and the straightening mechanism are arranged in the box body. [0003] The operation process of the spiral steel bar bending machine in the prior art is as follows: firstly, the coiled steel bar is manually passed through the traction mechanism and then introduced into the straightening mechanism. Driven by the motor of...
