Product Description:
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.
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.
