Punch press

The invention provides a punch press, which is used for machining two workpieces connected in series together through process bars. The punch press comprises a rack and two mounting parts which are mounted at two ends of the rack in the width direction respectively; clamping mechanisms are arranged at the mounting parts and used for clamping one ends, away from the process bars, of the two workpieces; the two mounting parts are configured to at least lift and fall synchronously in the height direction of the rack, the punch press further comprises a supporting mechanism, and the supporting mechanism is configured to follow synchronous lifting and falling of the two mounting parts; the supporting mechanism comprises a bracket and a bearing part which is connected to the bracket and extendsto the two workpieces clamped by the clamping mechanisms; the bearing part is in contact matching with the bottom of the workpieces close to one ends of the process bars, and therefore, bearing of thetwo workpieces is formed
