た。As described above, the tube expanding device according to the present invention is
Since the control device is integrally or separately provided with heat exchange recognition means for detecting the entire length of each heat exchanger to be sandwiched, different types of heat exchangers are transferred by the heat exchanger transfer means. Also, the expansion / contraction dimension of the pressing plate is automatically adjusted according to the total height of the heat exchanger. Therefore, unlike the conventional case, it is not necessary to input the heat exchanger type into the control device at any time, and it is possible to randomly expand different types of heat exchangers.
