Abstract

The invention relates to the mechanical technology field of reinforcing bar processing, which is a reinforcing bar straightening cutter, comprising a frame, a drive mechanism, a drawing mechanism, a straightening mechanism, a shearing and cutting mechanism and a material-holding frame. One front end of a straightening die casing of the straightening cutter is provided with a guide fin with a front flaring, which is convenient for the reinforcing bar to penetrate. The shearing and cutting mechanism consists of a driving cutter, a driven cutter, a shearing double roller, a signal generator, a clutch mechanism, a basic reset mechanism of cutter and an accurate reset mechanism of cutter. When then signal generator gives a shearing signal, the clutch mechanism of the clutch receives the signal to conduct dynamic clutch. After the reinforcing bar is cut, the driving cutter and the driven cutter return to a starting position via the basic reset mechanism of the cutter. The interaction of a positioning pin and a spiral groove of the accurate reset mechanism of the cutter make the driving cutter and the driven cutter return back to the starting position, thereby realizing precision cutting of the reinforcing bar and improving automatization.

Description

technical field [0001] The invention relates to the technical field of steel bar processing machinery, in particular to a steel bar straightening and cutting machine. Background technique [0002] With the increasingly wide application of steel bar straightening and cutting machine, while realizing the straightening and cutting function, the requirements for the dimensional accuracy and work efficiency of its processed steel bar are also continuously improved. At present, although there are many types of steel bar straightening and cutting machines, which are reflected in the differences in straightening mechanisms, shearing mechanisms, and power transmission mechanisms, it is common that the length and size of steel bars during processing are not easy to control, the error of steel bar length is large, and there is material waste. , The problem of low utilization rate. Contents of the invention [0003] The object of the present invention is to provide a steel bar straig...
