Claim:
1. A brake press, comprising: a movable frame comprising a first side support and a second side support, an upper frame assembly and a lower frame assembly, the upper frame assembly comprising an upper cross member connected to first ends of the first and second side supports, and the lower frame assembly comprising a lower cross member connected to second ends of the first and second side supports, the second ends opposite the first ends of the first and second side supports, the frame defining a vertical plane, the frame comprising a punch edge movable with said upper cross member, the punch edge extending towards the lower cross member and the upper cross member pivotable with respect to at least one of the first and second side supports; a stationary press assembly comprising a first press support, a second press support, and a die supported directly or indirectly by the first and second press supports and facing the punch edge, the first and second press supports connected to each other to define an elongated opening between them, a first end of the press assembly connected to a first guide and a second end of the press assembly opposite the first end connected to a second guide, the first guide configured such that the first side support travels vertically with respect to the first guide as the frame travels in the vertical plane, the second guide configured such that the second side support travels vertically with respect to the second guide as the frame travels in the vertical plane; and a power assembly comprising at least two hydraulic rams, a hydraulic power unit, and an input control assembly connected to the at least two hydraulic rams and the hydraulic power unit, the at least two hydraulic rams supported by the lower cross member and connected to the press assembly such that activation of the power assembly by the input control assembly controls the motion of the frame assembly in the vertical plane such that the punch edge moves towards and away from the press assembly.
