Background art
Background art
[0002] Before a wheel rim is formed, the steel plate is to be cut into strips, a rim blank ring is manufactured after rounding, butt welding and welding seam flattening. The blank rim ring is put into the rim spinning machine for spinning forming. Currently an external pressing type and an internal supporting type wheel rim forming process are available, and difference between them lies in fixing external molds or internal molds, and then rotating the internal molds or external molds to give plastic transformation to the blank rim ring. The present invention refers to an internal support type wheel rim rolling machine, wherein a blank ring is sleeved onto an upper part of a rotating drum of a rotating mechanism, and a self-locking positioning device is started to fix the blank ring;
the blank ring is pressed and attached on an internal wall of a positioning mold from inside to outside by internal molds provided on the rotation drum controlled by a control device according to operational sequence to have the blank rim ring expanding radially while rotary extruded. In this way, metal at both ends of the blank rim ring is pushed to plastically slide towards the middle section. Oil ducts in existing inner support type rim spinning press is assembled from an upper part and a lower part. Upon a long-term use, due to the fact that oil pressure is constantly changing during operation, leakage at the connection part tends to occur, so that the product is liable to damage when pressure is insufficient during a loss of pressure.
