The D51 Type Vertical Ring Rolling Machine is advanced forging automation equipment featuring a Hydraulic Machine Main Drive for efficient, precise operations. It offers multiple specifications for flexible customization to diverse production needs. With excellent rigidity ensuring stable operation and durability, its key process advantage is One Round Rolling Forming, enabling seamless material shaping in a single cycle. This machine delivers high performance, precision, and consistent output quality across automotive, aerospace, construction, and other industrial applications.
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.

The DRC-D51Y vertical ring rolling machine is suitable for the hot rolling and expansion process of ring hair, and is widely used in the processing and production of non welded ring parts such as bearings, flat welding flanges, large diameter flanges, and small thin-walled barrel parts. It can roll various metal materials, including high-temperature alloy steel, bearing steel, ordinary carbon steel, copper, and aluminum, and has low requirements for front-end drilling, which can improve production efficiency and product accuracy.
