PROBLEM TO BE SOLVED: To provide a crank press in which the volume required for a driving source is suppressed, further, the area occupied in a factory is suppressed, and also, rigidity is highly maintained, and which can punch a product in a state of two lines to a long shape steel sheet by one crank press.SOLUTION: Crank shafts 2 are disposed on both the sides of a rotating part 14 rotating by torque by a driving source 12 mutually parallelly as a pair in a state where the shaft direction is turned to the feeding direction F of a long shape steel sheet 8. Sliders 4 each disposed with an upper die part 61 and tables 5 each disposed with a lower die part 62 are disposed as a pair correspondingly to a pair of the crank shafts 2. The crank shaft 2 disposed on the upstream side in the feeding direction F and the crank shaft 2 disposed on the downstream side in the feeding direction F are disposed in the horizontal directions in an offset state to each other. The respective sliders 4 are slide-supported by slide guides 3 provided at all the directions of the feeding direction F and the horizontal direction to the respective crank shafts 2. |
