Product Desciption
D51-250 Gear blank flange making hot roller ring rolling machine
D51high quality ring rolling machine/iron ring making machine is widely used in manufacturing bearing outer ring,gearingblank,pipeline flange,welding neck flange in the fields of machinery,auto,train,ship,petroleum and chemicals,aerospace,atomic
energy,wind generator.It has advantages of rolling and forming at one time,high production efficiency,improve blank precision,
reduce turning remainder,improve steel utilization,improve cutting performance,improve inner quality of forging, good economic benefit.
[Performance Characteristics]
Compared with open die forging, ring rolling close die forging has advantages as follow:
1.High efficiency.It is 3-4 times than open die forging,the yield is dozens of times.Large,middle,small scale circular forgings can be
machined.
2.High material utilization.high dimension precision,forging tolerance is 1/3-1/4 time than open die forging.If adopt coining, the
forging tolerance is down to 0.1-0.05 mini,save 30%-60% material,and machining time,reduce the cost,have good economic benefit.
3.The ring rolling forgings have smooth surface, using precision forging can replace machining.
4.Good product quality. Rolling of metal fiber ring continuously distributed in the circumferential direction , and the force and wear
parts used to adapt. In most cases, the internal ring rolling dense , fine grain size , mechanical properties significantly higher than
other methods for processing the ring
5.It can machine complicated shaped forgings.It is difficulty to realize in open die forging equipment.
6.Small equipment tonnage,large processing range.Ring Rolling partial pressure forming process is a continuous accumulation of
small deformation , small contact area between the work piece and the mold, so a small force needed to deform , small equipment tonnage.
[Working Principle]
Heat the ring blank to 950-1050ºC,and put it around the back-up roller,then make the rotating roller down to rolling work piece,the thickness
of work piece decreases,perimeter extends and the hole expands.The roller stabilize and full circle in the processing.The roller begin to rotate
when predefined dimension is finish,meanwhile the roller 1 up to original position,the processing is finished.
Ring rolling machines are precisely adapted to meet the customer's requirements and rolls both profiled and rectangular rings with a high degree
of precision as well as cost-effectively.The machine concept is particularly maintenance and user-friendly.
Ring rolling machines are suitable for producing rings for the following applications: Flanges, Bearings, Gears, Wheels, Sleeves, Rings in the
automobile, aerospace, oil & gas industry etc.
Advantages:
1. High material utilization
2. Good quality
3. Good working conditions, high productivity
4. Low production costs
Ring rolling machine are divided into the radial rolling and radial-axial rolling(D53K series,CNC controlled). The radial rolling are divided into
vertical type (D51 series) .
