Comprehensive Introduction to Ring Rolling Machine

Ring rolling machine, also known as a ring rolling mill, ring forging machine, or expanding machine, is a piece of equipment used for plastic deformation of ring-shaped parts. Through the ring rolling machine, continuous local plastic deformation can be generated in the ring, thereby reducing the wall thickness, increasing the diameter, and forming the cross-sectional contour.

Working Principle:

The working principle of the ring rolling machine is to apply pressure to the ring-shaped blank with two or more rolls to cause plastic deformation of the blank. By controlling the shape, gap, and movement mode of the rolls, accurate forming of the ring can be realized.

Main Features:

• High production efficiency: The ring rolling machine can be processed continuously, with much higher production efficiency than traditional processing methods.
• Good product quality: The ring parts processed by the ring rolling machine have high dimensional accuracy and good surface quality, which can reduce subsequent processing processes.
• High material utilization rate: The ring rolling machine can make full use of the material and reduce material waste.
• Wide range of applications: Ring rolling machines are widely used in bearing, automotive, machinery, chemical and other industries to produce ring-shaped parts of various shapes and sizes.

Application Fields:

• Bearing industry: Production of bearing rings, rolling balls, etc.
• Automotive industry: Production of gears, flanges, etc.
• Machinery industry: Production of various types of flanges, hubs, etc.
• Chemical industry: Production of pipeline flanges, etc.

Classification:

According to different structures and functions, ring rolling machines can be divided into various types, such as vertical ring rolling machines, horizontal ring rolling machines, and closed ring rolling machines.

Development Trend:

With the development of manufacturing industry, the requirements for the accuracy and efficiency of ring-shaped parts are getting higher and higher. The ring rolling machine is also constantly developing towards automation, intelligence, and high precision.
