Description

Technical field:

[0001] The utility model relates to the technical field of fan processing equipment, and more specifically to a forming and grinding mechanism for a motor bracket of an axial flow fan. Background technology:

[0002] Axial flow fans are fans whose airflow direction is in the same direction as the axis of the fan blades, such as electric fans and air conditioner outdoor fans. They are called "axial flow" because the air flows parallel to the fan axis.

[0003] A motor bracket needs to be installed between the motor and the wind tube in the existing axial flow fan. The existing motor bracket has a single integral part and a split part, which is V-shaped, such as the connecting support frame disclosed in an axial flow fan with an integrated impeller having Chinese patent application number 202320335578.7. The connecting support frame is generally formed by first cutting the steel plate into a block shape, and then using a steel plate bending machine to be bent multiple times. Since the steel plate is cut first, there will be more burrs on the wall surface at the cutting point, and the surface is not smooth enough, which affects the later installation and operation. Therefore, after bending, it is necessary to grind and remove burrs on both sides. The existing operations are all manual grinding, which is inefficient and requires a lot of manual labor.
