Description

A steel bar straightening and cutting machine for concrete pole production Technical Field

[0001] This utility model relates to the technical field of rebar straightening and cutting machines, specifically a rebar straightening and cutting machine for concrete pole production. Background Technology

[0002] The steel bars used in the production of concrete utility poles are mainly hot-rolled steel bars. These steel bars play a crucial role in the pole manufacturing process, enhancing the structural strength and durability of the pole. Specifically, the steel bars are firmly bonded to the concrete, sharing the load and preventing corrosion. The addition of steel bars significantly improves the pole's load-bearing capacity and bending resistance, ensuring stability under various environmental conditions. The concrete encapsulates the steel bars, effectively preventing them from being directly exposed to the air, thus preventing corrosion and extending the pole's service life.

[0003] As disclosed in the patent announcement number CN212191019U, a steel bar straightening and cutting machine includes a frame. From left to right, a first conveying pressure roller, a bearing seat, a straightening cylinder, a second conveying pressure roller, and a cutting blade are arranged on the top of the frame. A hollow shaft is provided at each end of the straightening cylinder. The hollow shaft is rotatably mounted on the bearing seat through bearings. A sprocket is also installed on the left hollow shaft. The sprocket is connected to a reduction motor through a chain. The straightening cylinder includes a rotating cylinder, end caps installed on both sides of the rotating cylinder, and several sets of straightening devices. The straightening devices include horizontal straightening devices and vertical straightening devices, which are installed alternately.

[0004] Although it allows adjustment of the distance between the upper and lower straightening rollers, and between the right and left straightening rollers, by rotating handles A and B, controlling the gap of the reinforcing bar to pass through on the same horizontal straight line, ensuring a high degree of straightness of the reinforcing bar, and ensuring that the upper and lower straightening rollers, and the right and left straightening rollers move in the same or opposite directions without deviation, making adjustment convenient and ensuring a high degree of coaxiality, by adjusting the distance between the upper and lower straightening rollers, and the distance between the right and left straightening rollers, the width of the reinforcing bar passing through can be gradually tightened, which can avoid the phenomenon of the reinforcing bar getting stuck at the beginning due to the large curvature of the reinforcing bar;

[0005] However, this does not solve the problem that existing rebar straightening and cutting machines are generally not conducive to the convenient integrated conveying, straightening, and cutting of rebars, making it difficult to straighten or cut the rebars, thus affecting the efficiency of the rebar straightening and cutting machine.
