One aspect of this disclosure provides an expansion rod holder for the assembly of fin and tube heat exchangers. The expansion rod holder includes a first plate having a first aperture therethrough and a ring located in the first aperture and that has a second aperture therethrough. The first and second apertures are configured to receive a tapered end of an expansion rod having an annular groove proximate the tapered end. A biasing member is located in the first aperture between the ring and a wall of the first aperture. The biasing member is configured to bias the ring in a first direction toward an opposite wall of the first aperture and into the annular groove. A method of manufacturing the expansion rod holder is also disclosed, as well as a tube expander system used to manufacture heat exchangers. |
