PROBLEM TO BE SOLVED: To provide a manufacturing device of a heat exchanger capable of manufacturing a plurality of kinds (at least two kinds) of heat exchangers by one manufacturing device, without requiring a preparatory plan change such as metal mold replacement.SOLUTION: A manufacturing device manufactures a plurality of kinds of heat exchangers of a different size from one long size corrugate fin 41, and comprises a carrying device 42 for carrying the long size corrugate fin in the carrying direction at a predetermined pitch, a plurality of trim punches 66 and 72 provided in a plurality in the width direction, a plurality of cutting devices 68 and 74 provided in a plurality in the width direction on the downstream side in the carrying direction of the respective trim punches and provided in the same position and a control part 64 for controlling so that the press timing of the mutual trim punches and the press timing of the mutual cutting devices become the mutually different timing and controlling so that the feed pitch of the carrying device 42 is set as integral multiplication of the greatest common divisor of mutual blank sizes of the respective heat exchangers.SELECTED DRAWING: Figure 3 |
