Product Description:
One of the key advantages of our D51Y vertical ring rolling machine is its reliability and durability, which combines high precision and high production capacity with excellent cost-effectiveness, and is highly recognized by small and medium-sized enterprises. This product is widely used in the processing and production of seamless ring parts such as bearings, flat welding flanges, high diameter flanges, and small thin-walled barrel shaped components. It is an ideal equipment for the hot rolling and expansion process of circular rough blanks.
Features:
Good process compatibility:
Due to its ability to roll various metal materials, high-temperature alloy steel, bearing steel, ordinary carbon steel, copper aluminum, etc., and low requirements for hole making at the front end, this vertical ring rolling machine has outstanding benefits when used in conjunction with general forging equipment, replacing the original saddle hole expanding process. It can be expanded and formed in one go, with high production efficiency and refined blank accuracy. It has significant effects on reducing turning allowance, improving steel utilization, cutting performance, and internal quality of forgings.
Small size and light weight:
The compact and lightweight design of the equipment facilitates flexible layout in the workshop for enterprises, without occupying too much valuable production space, which is extremely advantageous for small and medium-sized enterprises with limited space.
Good rigidity:
Under long-term and high-intensity working conditions, it can still maintain stable operation, effectively avoiding the impact of equipment deformation on processing accuracy and ensuring consistent product quality.
Sensitive manipulation:
Operators can quickly and accurately adjust equipment parameters according to different processing requirements, achieving precise control over the processing process and ensuring that the product meets high-precision requirements.

Applications:
The D51Y series vertical ring rolling machine (hole expanding machine) developed and produced by our company 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.
