This machine adopts a fully automatic hydraulic drive system, which is driven by an electric motor to produce stable rotational motion, ensuring a smooth spinning process with almost no impact and vibration. Therefore, the spun parts have high surface finish and uniform deformation, completely avoiding quality problems such as tearing. Its stability and ease of operation make it favored by manufacturers of air conditioners, heat pumps, centrifugal fans, radiators, etc. In addition, this machine shows obvious advantages in processing the expansion and valgus or closing inversion of various types of thin-walled hollow parts. The automatic internal spinning machine is specially designed for the internal spin forming of the air inlet reinforcement plate of air conditioning ventilators. Its unique feature is that the plate is fixed and the spinning wheel performs spinning operation inside the plate, which can spin multiple holes in a single plate. The equipment adopts automatic control and can handle straight edge, arc edge and other spinning needs.
