Furthermore, the frame strips are processed by the forming machine, the blanking specifications of the frame strips are consistent, each frame strip only needs to be bent once, the material required by the whole flange can be directly produced after the forming machine is debugged once, the blanking is simple, the preparation is simple, the procedures of cutting and the like are omitted in the production, the fingers are prevented from being scratched by the U-shaped grooves with the notches, and the production process is safer.
The utility model discloses a cabinet type centrifugal fan's flange structure's beneficial effect:
1. the utility model discloses a cabinet type centrifugal fan's flange structure has deducted in production processes such as tailorring, makes the production process safer.
2. The utility model discloses a cabinet type centrifugal fan's flange structure is when the unloading, and the material that whole flange needs is directly produced to the back of make-up machine debugging once, avoids twice to make production and processing more swift, and production efficiency is higher.
3. The utility model discloses a cabinet type centrifugal fan's flange structure reduces through the width with interior strip of pasting, and then reduces the area of contact with the fan wind gap, makes its area that shelters from to the fan wind gap reduce to the ventilation efficiency of fan has been increased.
