Professional customization Vertical small pneumatic ring rolling machine
We have professional and mature technology. In the second half of 2024, we have successively sold dozens of vertical ring rolling machines. Our strength can be seen from our sales volume. The ring rolling machines produced by our company are non-standard customized equipment. It is necessary to produce a ring rolling machine suitable for the customer's products based on the detailed product values provided by the customer. Meet the production needs of different customers,
We are China ring rolling machine supplier, specializing in the production of ring rolling machines for decades,
Since there are many models of vertical ring rolling machines, we first introduce the vertical small pneumatic ring rolling machines.
D51 ring rolling machine is most widely used in the bearing forging and flange forging industries. Various types of bearing rings and flange rings, including outer and inner rings, can be roll-formed, and the raceways and ribs of the rings can also be rolled out accordingly.
BRIEFLY DESCRIBE THE STRUCTURE OF VERTICAL SMALL PNEUMATIC RING ROLLING MACHINE

Electrical system requirements
1. The electrical system has overcurrent and short-circuit protection devices.
2. The electrical components adopt the Delixi brand and are of reliable quality.
3. Equipped with an independent electrical cabinet equipped with air switches, relay contactors and other electrical appliances.
Hydraulic system requirements
1. The hydraulic system is stable and there must be no oil leakage.
2. The hydraulic station is equipped with a water cooler, and the water source must be prepared by the user.
3. The hydraulic oil replacement interval is 1 year, and the daily maintenance interval is 1 month.
4. The main hydraulic components adopt domestic famous brand products.
According to our market research, we found that the market competition among sellers of flange rings, bearing rings, etc. is very fierce.
In order to win customers, some sellers independently process and refine materials to achieve uniqueness, so some ring forgings of special materials appear on the market.
