TUBE BLANK CORRECTING MEMBER FOR USE IN TEMPORARILY ASSEMBLING HEAT EXCHANGER, AND APPARATUS FOR AND METHOD OF TEMPORARILY ASSEMBLING HEAT EXCHANGER

摘要

A temporarily assembling apparatus comprises a support member 2 for supporting thereon heat exchange tube blanks P having their lengthwise direction positioned laterally, with their widthwise direction positioned vertically, and arranged from front rearward in parallel with opposite left and right ends thereof aligned respectively, and the fins F arranged between the respective pairs of adjacent tube blanks. Two header supports 3 are arranged respectively at the left and right sides of the support member 2 and movable leftward or rightward. A pair of left and right tube blank correcting members 19 are each in the form of a plate extending from the front rearward and having a plurality of blank fitting slits 23 formed in a side edge thereof and arranged from the front rearward at the same spacing as the heat exchange tubes to be produced of the heat exchanger. Each of the blank correcting members is movable between a correcting position wherein the corresponding ends of all the tube blanks P as supported on the support member 2 are fitted into the respective slits 23 and a noncorrecting position wherein the tube blanks P are not fitted into the slits 23. In temporarily assembling components, the opposie ends of the heat exchange blanks P can be reliably placed into insertion holes of respective headers.
