D51
Vertical ring rolling machine producing bearing outer rings, gear blanks and flanges in a single rolling operation, improving blank precision and material efficiency compared with free forging.
Overview
The D51 series vertical type ring rolling machine is widely used in manufacturing bearing outer rings, gearing blanks, pipeline flanges and welding neck flanges.
It delivers rolling and forming at one time, high production efficiency, improved blank precision, reduced turning remainder, improved steel utilization, improved cutting performance, improved inner quality of the forging and good economic benefit.
Key data
Full technical parameters are confirmed together with our engineers, based on your part and production volume.
Features
The vertical ring rolling machine adopts the rolling gear system of the fixed expansion ring, which has high axial positioning accuracy, reliable connection and convenient replacement, reducing the consumption of non-productive hours and improving labour productivity.
The main parts are made of cast steel and alloy steel and are reasonably heat treated. The bed, base and other large parts are of steel plate welded structure, which ensures the stability and durability of the equipment.
The vertical ring rolling machine is widely used in the processing and production of non-welded ring parts such as bearings, flat welding flanges, large diameter flanges and small thin-walled barrel parts.
It has a high degree of automation, small size, light weight, good rigidity and sensitive operation, which suits small and medium-sized enterprises.
