The invention discloses a die for bending a workpiece and a control method thereof, the die comprises an upper die plate and a lower die plate which are oppositely arranged, a workpiece to be machined is clamped between the upper die plate and the lower die plate, and the die further comprises a bending assembly which is arranged on the side of the upper die plate and is provided iwth a bending block that can rotate towards the side of the lower die plate and is used for bending the workpiece. According to the die, the bending assembly is arranged, the bending block of the bending assembly rotates towards the side of the lower die plate to bend the workpiece, in the bending process, due to the fact that the bending block rotates, the vertical impact force generated between the bending block and the workpiece and rolling contact between the bending block and the workpiece are avoided, and the workpiece is rotationally bent according to the track of a formed round corner; the workpiece bulging, film breaking, p
