Abstract
The invention discloses a die for bending materials. The die comprises an upper die holder with a punch, and a lower die holder with a bending supporting point, wherein a base of the upper die holder is hinged to the tail part of the punch; a propping component is arranged on the lower die holder, and when the propping component is propped against the punch, the propping force applied on the punch can drive the punch to rotate towards the bending direction of a material. Because the punch can rotate, the punching point on the punch moves in the transverse direction, and further, the distance between the punching point propped against the bending edge of the material on the punch and the bending point of the material in the horizontal direction can be shortened, so that the material can form a larger bending angle. When the die is applied on a punching machine with an upper table plate and a lower table plate which have adjustable closing heights, springback compensation can be realized by the adjustment of the closing height of the upper table plate and the lower table plate. The die can effectively solve the problems that the limit to the bending angle of the material is large, and the springback is increased. The invention further discloses a punching machine which comprises the die.
