Description

Technical Field

[0001] The utility model belongs to the technical field of fan processing, and in particular relates to a fan tube panel spinning machine. Background Art

[0002] Axial flow fans generally require a panel to be spun out at one end of the air duct, and mounting holes to be opened on the panel to facilitate subsequent assembly.

[0003] In the prior art, the edges of air ducts are typically processed using a spinning machine to form panels. For example, patent CN112916705A discloses a sheet metal air guide ring edge processing spinning machine. This machine uses an expansion mechanism to expand and secure the inner ring of the air guide ring. A rotating assembly then rotates a turntable mechanism. A lifting and adjusting mechanism then drives the rotating assembly to lower the turntable mechanism, processing and shaping the edge of the air guide ring on the expansion mechanism.

[0004] However, the rotating assembly and turntable mechanism of the above-mentioned prior art are mounted on one side of the linear guide rail. After long-term reciprocating use, the end of the rotating assembly may lower or raise its head due to uneven force, resulting in poor surface consistency of the workpiece. Utility Model Content
