The D51Y series vertical ring rolling machine (hole expanding machine) developed and produced by DORCO is an ideal equipment for the hot rolling and expanding process of circular rough blanks. This product is mainly used in the processing and production of non welded ring parts such as bearings, flat welding flanges, high diameter flanges, and small thin-walled barrel shaped components. After upsetting and punching, forging enterprises use this equipment to expand holes, which can perfectly connect the entire forging process.
Mature technology and advanced technology, every detail has been
carefully designed and rigorously inspected. During the production
process, the equipment runs smoothly, greatly improving production
efficiency and environmental quality.
The D51Y vertical ring rolling machine adopts a ring expansion
fixed rolling wheel system, which has high axial positioning
accuracy and simplifies the mechanical processing of the rolling
wheel;
There is a square hole behind the conical hole at the end of the
lower support shaft. The connection between the rolling and the
lower support shaft is reliable, easy to replace, reduces non
productive labor consumption, and improves labor productivity;
The main components of D51Y ring rolling machine are made of cast
steel and high-quality alloy steel, and have undergone reasonable
heat treatment. The bed, base and other large parts are welded with
steel plates, which have good rigidity, light weight, clear and
beautiful shape.
Before leaving the factory, each device undergoes operational
testing and precision inspection. Each device undergoes
comprehensive operation debugging and precision inspection before
leaving the factory. Only equipment that meets high standard
requirements in all indicators will be delivered to customers,
providing reliable quality assurance and reducing the risk of
equipment failure during use.

Widely used in the hot rolling of various annular blanks in the bearing forging, automotive gear, and flange manufacturing industries. In addition, the company has also developed an automated production line that is compatible with the ring rolling machine. The degree of automation has significantly increased, greatly improving the quality and production efficiency of the ring components, and reducing the human resource costs of the enterprise.
