Problems solved by technology
[0005] 1. Because the bearing force of a pair of cut-diameter rolls is much smaller than that of the rolling rolls of the main rolling mill, the structure of the cut-diameter rolls is too large, and there is a defect of high cost
[0006] 2. The gap adjustment of the diameter-cutting roller is small, and the motor transmission mechanism is used to drive the motor compression mechanism to adjust the gap, which has the disadvantages of complex structure and high cost
[0007] 3. Before the steel bar enters the reducing mill, the shape of the steel bar is irregular, and the steel bar is prone to movement after entering the reducing mill, causing the mill after cutting the diameter to seriously affect the quality of the finishing process in the subsequent process

The invention discloses a passive reducing rolling mill, which comprises a machine frame, a reducing adjustment mechanism arranged on the machine frame, a reducing roller sheet bearing pedestal mechanism comprising a pair of reducing roller sheets and a straightening mechanism, wherein the straightening mechanism is arranged on the machine frame at a steel bar inlet of the reducing adjustment mechanism; the reducing adjustment mechanism is a transmission mechanism formed by a worm gear and a worm; and the output end of the reducing adjustment mechanism is connected on the reducing roller sheet bearing pedestal mechanism by a lever mechanism. The passive reducing rolling mill has the advantages that the straightening mechanism is arranged additionally, so that the diameter cutting process is stable in operation, the excellent foundation is laid for finish rolling in the subsequent process after the diameter cutting process, and the rolling quality of steel bars is improved; and the reducing adjustment mechanism is operated manually, and is flexible, convenient and easy to operate, ensures the safety of operators to the maximum degree, and realizes the humanized operating mode. In addition, the passive reducing rolling mill also has the advantages of simple structure, safety, high production efficiency, stable operation, energy conservation and low machining cost, and it is simple, convenient and easy to operate the mill.
Description
technical field [0001] The invention relates to a numerically controlled production line for double-sided rib steel bars, in particular to a numerically controlled production line for double-side rib steel bars with a passive reducing rolling mill. Background technique [0002] The CNC double-sided rib steel bar production line is a processing equipment for steel bars with crescent ribs on both sides by descaling, reducing diameter, scoring, heating, straightening, cutting to length, and collecting materials from hot-rolled round wire rods. The CNC double-ribbed steel bar production line is equipped with a reducing mill, which is designed to roll the symmetrical sides of the steel bar into a flat shape. The reducing mill includes an active reducing mill and a passive reducing mill. The shearing rolls of the passive reducing mill are not driven by power, and the frictional force of the moving steel bar drives the shearing rolls to rotate to reduce the diameter of the steel ba...
