The invention provides a double-coil shearing and bending machine. The double-coil shearing and bending machine comprises a rack and a shearing and bending mechanism. The shearing and bending mechanism comprises an air cylinder, a slide rail and a knife holder which are fixed to the rack. A piston rod of the air cylinder is connected with a push rod. The front end of the push rod is provided with a shearing knife and a bending knife. The slide rail is sleeved with a movable block. The movable block drives a locating block to do front-back reciprocating motion. A compression spring is arranged between the movable block and the rack; and in a free state, the locating block is pressed on the knife holder, a stop lever is arranged on the push rod, and the stop lever drives the locating block to retreat when the piston rod retracts. The double-coil shearing and bending machine is reasonable in shearing and bending structure design, stable and reliable in structure and low in failure rate. The double-coil shearing and bending machine conducts shearing and bending synchronously and is high in speed, and the bending quality of coils is stable. The double-coil shearing and bending machine can be connected with an automatic binding machine to realize shearing, bending and binding integrated mechanized production.
