An apparatus for forming an inclined-blade blower wheel is provided. A plurality of blades are initially positioned between first and second end caps, and a first engagement member mates with the first end cap, while a second engagement member mates with the second end cap. First and second end motors are configured to independently rotate the first and second engagement members. A crimping roller coupled to a crimping motor contacts and compresses a circumference of the first and second end caps to a plurality of blades. A controller is configured to rotate the first engagement member a predetermined amount with respect to the second engagement member, a then circumferential speed of the first and second end caps and the crimping roller is synchronized, therein fixing a desired longitudinal pitch of the plurality of blades between the first and second end caps.

Apparatus for forming a blower wheel having longitudinally inclined blades

A method for forming an inclined-blade blower wheel is provided by arranging a plurality of blades about respective circumferences of first and second end caps. The plurality of blades extend longitudinally between the first and second end caps and parallel to an axis defined by respective centers of the first and second end caps. The first end cap is rotated with respect to the second end cap a predetermined amount, therein skewing the plurality of blades at a desired longitudinal pitch between the first end cap and second end cap. The first end cap and second end cap are then rotated in unison while crimping the circumferences of the first end cap and second end cap, therein securing the plurality of blades to the first and second end caps and fixing the desired longitudinal pitch of the plurality of blades from the first end cap to the second end cap.

Method for forming a blower wheel having longitudinally inclined blades

The present invention is directed to a machine and a method for assembling blower wheels. The machine comprises a drive motor rotatably coupled to a first die, whereon a plurality of blower wheel components reside. A second die is oppositely disposed from the first die, and is operable to engage one or more of the plurality of blower wheel components. A transfer gear assembly rotatably couples the first die and the second die, wherein a rotation of the first die generally transfers to the second die, and wherein the rotation of first die and the second die is generally synchronized. A two-stage press is coupled to the first die and the second die, and is operable to axially compress the blower wheel components between the first die and the second die. A deforming member is operable to deform the hub during the compression of the blower wheel components. One or more springs couple the second die to the press, wherein the second die is operable to axially translate with respect to the press.
