The forced shearing method comprises the steps that: (1) the time of operation of a finished product line is measured by using a pulse counting method through an encoder; (2) the length of a reinforcing steel bar is calculated, wherein the calculation method is as follows: the length of the reinforcing steel bar=operation time*operation velocity; and (3) if the time scale shear shears while the reinforcing steel bar is 5m longer than a set length and when the time scale shear transmits a shearing signal, the steps (1) is executed repeatedly; and if the time scale shear does not shear while the reinforcing steel bar is 5m longer than the set length, a forced shearing signal is transmitted so as to force the time scale shear to shear; and after the time scale shear transmits the shearing signal, the step (1) is executed repeatedly. And meanwhile, the invention also discloses a forced shearing system of the time scale shear. With the adoption of the forced shearing method and the forced shearing system, an accident of material overflowing is avoided; and the human body security of operation staff is ensured.
