Heating oven for dynamo-electric machine component manufacture
First Claim
1. A heating oven for processing dynamo-electric machine components, comprising:
- a movable support structure;
a plurality of cradles disposed on said movable support structure, wherein each of said cradles has a cavity having an air-flow inlet opening and an air-flow outlet opening; and
means for directing heated air through each of said cradles'"'"' cavity from said inlet opening to said outlet opening along flow paths which pass over an in-process dynamo-electric machine component disposed in said cavity wherein said cavity has a tubular shape, wherein said outlet opening is disposed on the tubular side of said cavity, wherein substantial portions of said flow paths are substantially parallel to the longitudinal axis of said cavity, and wherein said flow paths exit said cavity through said outlet opening in directions which are substantially normal to said longitudinal axis.

Abstract
A heating oven for use in dynamo-electric machine component manufacture is provided. The oven uses forced air heating to raise the temperature of in-process component subassemblies to suitable process temperatures. The heating oven includes a rotating drum mounted in a cabinet. A number of open-ended tubular cradles are disposed in circular arrays between the drum faces. Batches of component subassemblies may be individually loaded into the cradles for heat treatment. Air flow channels are set up in the oven cabinet to evenly distribute heated air through individual cradles. Heated air after passing over the individual in-process subassemblies, exits the cradles through side slots in the cradle walls into the interior of the drum. The exiting air is reheated and recirculated through the heating oven.
