The D51K CNC vertical ring rolling mill is an advanced equipment for efficient and precise ring rolling. Its main transmission adopts hydraulic or pneumatic mode, which flexibly adapts to diverse production needs.
One of the core advantages of this device is its powerful radial rolling capacity (50-800 KN), which enables it to easily handle ring rolling tasks of different materials and sizes. Whether it's small workpieces or large-scale industrial production, they can handle it with ease.
In terms of processing range, the equipment provides a ring height adaptability of 40 to 300 millimeters, providing sufficient flexibility to meet various design specifications and requirements. This wide range of processing heights makes it an ideal choice for manufacturers to meet diverse product demands.
Safety is always the top priority in design. D51K is equipped with an emergency stop button, which can immediately shut down in case of sudden situations; Comprehensive safety protection devices effectively prevent accidental injuries during operation; The overload protection function ensures the stability and service life of the equipment during long-term operation.
High quality product performance: Through special rolling process optimization, the internal structure of the ring is made uniform, significantly improving the strength, hardness, and fatigue resistance of the ring. It can be applied to work scenarios with extremely high requirements for ring performance.
The ring rolling machine mainly consists of the following parts:
The main transmission box, body, main roller slider, centering mechanism, measuring device, hydraulic system, hydraulic pipeline, control system, lubrication system, cooling system, foundation, etc.
