Patent ID: 10046379

Abstract:
What is disclosed is a fin forming machine for making fins for heat exchanger cores, or the like, in which the fin forming machine has three major drives and separate controls; the top and bottom drives control the vertical opening and closing of fin forming dies under programmable control in accordance with CNC technology; and a center drive under the control of a separate programmable system which controls horizontal movement of the feedstock into intersection with the top and bottom forming dies to incrementally halt the movement of the feedstock as it intersects with the forming dies upon convergence during fin formation and then advances it a controllable distance for the next fin forming action. These three drive systems being seamlessly variable and controllable during operation, maintain a high degree of calibration of the formation of each fin to maintain fin height and spacing within very close tolerances, which calibrations are achieved without shutting down machine operation. Positive control of all drive systems minimizes overtravel of the forming dies.
