Abstract

PURPOSE:To automate a tube enlarging work by progressively holding heat exchangers to be enlarged, transferring them to a specific enlarging device from one direction, positioning them at the enlarging device, taking out the heat exchanger after enlarging is completed, and again transferring them to one direction. CONSTITUTION:A mandrel for enlarging is forcibly pressed inside a tube of a heat exchanger 6. A transferring device 1 holds the heat exchanger 6 and transfers it from one direction crossing to a reciprocating direction of a reciprocation acting body 11. A tube enlarging device 10 having the reciprocation acting body 11 to reciprocate the mandrel opposing to the tube is installed. The heat exchanger 6 carried nearby this enlarging device 10 is moved to an enlarging possible range of the enlarging device 10 with a heat exchanger positioning transferring body 3 installed in freely attacnablly and detacnablly to this enlarging device 10, then enlarging is executed. Then, after the heat exchanger 6 after enlarged is detacled from the enlarging possible range of the enlarging device 10 through the heat exchanger positioning transferring body 3 and it is reversely moved, again the heat exchanger is returned to one direction and transferred.

By means of the heat exchanger positioning and transfer means provided so as to come into contact with and separate from the tube expanding device 10
Of the pipe expander, and after the positioning, the heat exchanger 6 is expanded, and then the heat exchanger 6 after the pipe expansion is moved backward to the transfer device 1 away from the pipe expandable region of the pipe expander 10 via the heat exchanger positioning transfer means. After that, the point is that the paper is conveyed back by returning to one direction again.

[0010]

In the method of transporting the heat exchanger having the above-mentioned structure, the reciprocating body which reciprocates with the mandrel facing the pipe so that the mandrel for expanding the pipe can be press-fitted into the pipe of the heat exchanger 6. The heat exchanger 6 is held and conveyed from one direction intersecting with the reciprocating motion direction of the reciprocating body 11 by the conveying device 1 arranged near the pipe expanding device 10 including the pipe expanding device 10. The heat exchanger 6 conveyed to the vicinity is moved to a pipe expandable region of the pipe expanding device 10 by the heat exchanger positioning transfer means provided to the pipe expanding device 10 so as to be separable from the pipe expanding device 10, and after positioning, pipe expansion is performed.
