A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

The present invention relates to a method and a device for manufacturing plate part blanks for a heat exchanger. A sheet material (2) in the form of continuous sheeting is worked between two rolls (5, 6) with opposite surface patterns (7, 7′, 8) to form profiled plate part blanks (3, 3′,3″) into the sheet material (2) so that the rolls (5, 6) are synchronized to rotate at substantially same rate by controlling the rotation of them in relation to each other with common synchronization gear (9), which gear is coupled to the rolls (5, 6) by means of shafts (10, 11) with disk pack or gear couplings.

A rotatable buffer turret apparatus on which plural pairs of punches and dies to be set on a turret of a turret punch press are set, includes an upper buffer turret on which punch attachment holes in which the punches can be set are arranged circularly, and a lower buffer turret on which die attachment holes that is associated with the punch attachment holes and in which the dies can be set are arranged circularly. The upper and lower buffer turrets are rotatably attached to a single rotary shaft. A diameter of the lower buffer turret is made larger than a diameter of the upper buffer turret. The die attachment holes are formed in a circular die attachment area having a diameter larger than the diameter of the upper buffer turret. According to the apparatus, a tool exchange manually operated by an operator can be done easily and efficiently.
