Manufacturing apparatus for flattened tube fins

摘要

A manufacturing apparatus that manufactures flattened tube fins, in which cutaway portions for inserting flattened tubes for heat exchanging are formed, includes: a press apparatus provided with a mold apparatus that forms the cutaway portions in an unmachined metal thin plate to produce a metal strip; an inter-row slit apparatus cutting the metal strip into predetermined widths to form a plurality of metal strips of a product width; a cutoff apparatus cutting each metal strip of the product width into predetermined lengths; a holding apparatus that holds a plurality of metal strips of the product width that protrude from a downstream side in the conveying direction of the cutoff apparatus; and a stacker apparatus for stacking the flattened tube fins that have been cut into predetermined lengths by the cutoff apparatus.

主权项

1. A manufacturing apparatus that manufactures flattened tube fins wherein flattened tubes for heat exchanging are inserted into cutaway portions formed from one side toward another side in a width direction, the manufacturing apparatus comprising:
a press apparatus equipped with a mold apparatus that forms the cutaway portions in an unmachined thin plate of metal to produce a metal strip; an inter-row slit apparatus which cuts the metal strip, in which the cutaway portions have been formed, into predetermined widths to form a plurality of metal strips of a product width that are arranged in the width direction; a cutoff apparatus that cuts each of the plurality of metal strips of the product width into predetermined lengths; a holding apparatus that holds the plurality of metal strips of the product width that have been formed by the inter-row slit apparatus, have been fed in the conveying direction, have passed the cutoff apparatus, and protrude out from a downstream side in the conveying direction of the cutoff apparatus, guides a conveying direction of the metal strips of the product width, and maintains a held state even after cutting into the predetermined lengths by the cutoff apparatus to form the flattened tube fins; and a stacker apparatus for stacking the flattened tube fins cut into the predetermined lengths by the cutoff apparatus, wherein the holding apparatus includes pairs of supports that are provided so as to be capable of moving toward and away from one another between a position to the side of the metal strips of the product width fed from the inter-row slit apparatus and a holding position for the metal strips of the product width, and the stacker apparatus includes: a plurality of stacking pins that are inserted through the cutaway portion of the flattened tube fins and are aligned in a length direction of the flattened tube fins in order to stack the flattened tube fins held by the holding apparatus; and a raising/lowering means for raising and lowering the stacking pins in a direction of the holding apparatus.
