The D51Y vertical ring rolling machine is one of our company's main products, which can roll and shape circular parts such as bearing rings, gear blanks, pipe flanges, copper, aluminum, etc. in one go according to your desired shape.
D51Y ring rolling machine, with a novel and reasonable structure, draws on user experience, adopts the advantages of some imported equipment, and selects new supporting parts;
The guide surface of the slider is 5-6 times longer than the stroke, with a rectangular cross-section, reasonable force distribution, high guiding accuracy, and long service life;
The cylinder adopts the international standard cylinder with polyurethane YX sealing ring, which is reliable in sealing, wear-resistant, and has low motion resistance;
The precision rolling mechanism adopts synchronous belt transmission, which is easy to operate, stable in operation, and has a large adjustable range;
The selection and distribution of spindle bearings are relatively reasonable, and the rolling wheel has high rotational accuracy;
The lower support part is fixed in the rectangular frame with a wedge iron, making adjustment and maintenance very convenient;
The lower support bearing has good sealing to ensure normal operation in harsh environments;
We have selected a standard reducer and a Y-shaped motor, both of which are placed on the same seat, with a compact structure and easy installation and maintenance;
Compressed air is released through a muffler, eliminating noise pollution.
