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.
