T-shaped hollow elevator guide rail blank punching production line and working method thereof

The invention discloses a T-shaped hollow elevator guide rail blank punching production line and a working method thereof. Belongs to the technical field of elevator guide rail machining and comprises a feeding component, a first rolling feeding component, a cutting machine tool, a second rolling feeding component, a front-end punching machine tool, a third rolling feeding component, a rear-end punching machine tool and a measuring rolling feeding component which are linearly arranged. Full automation of the whole process of flattening, rolling, cutting and punching of the T-shaped hollow elevator guide rail blank is achieved; in the rolling and conveying process of the roller, unsmooth rolling and conveying of the roller caused by thickness errors of the coil steel or the situation that the roller crushes the coil steel until rolling and conveying cannot be achieved is avoided. In the process that the roller rolls and conveys the T-shaped hollow elevator guide rail blank, the two sets of guide wheel sets alw
