Product Description:
DORCO D51K CNC vertical ring rolling machine adopts servo motor drive (through reducer) to achieve rolling feed, significantly reducing temperature influence, improving feed accuracy and stability; As the processing center of the entire control system, PLC is responsible for monitoring the entire machining process according to the process parameters set by the touch screen. It completes real-time control of the electro-hydraulic proportional valve through the digital to analog conversion module, achieves control of the hydraulic cylinder stroke position, and obtains motion position feedback information through the encoder interface control.
Use a grating ruler to actively measure the real-time changes in the size of the ring during the rolling process. When the size reaches the preset value of the product, start rounding.
Features:
The CNC vertical ring rolling machine has been upgraded on the original basis, with higher precision and more powerful functions;A rolling process that can achieve a larger rolling ratio and roll more complex shaped products;The signal wheel is controlled by servo and actively participates in rolling and forming, which can greatly improve and compensate for the rounded corner defects caused by blank problems in the product;A newly designed human-machine interface with one click storage and one click switching of processing parameters;Without the need for manual mechanical adjustment of the ring rolling machine, different process products can be processed by inputting parameters, reducing the difficulty of manual adjustment. Even ordinary operators can easily operate with simple training.The loading and unloading space is larger, making it more suitable for combining with robotic arms to achieve forging automation.

Applications:
The D51K series vertical ring rolling machine is an ideal equipment for the hot rolling and expansion process of circular blanks. This equipment 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 the hole, which can perfectly connect the entire forging process.
