For industries needs to process large ring parts, CNC ring rolling machines have become indispensable equipment. In the field of ring rolling, vertical CNC ring rolling machines are more efficient and precise. At present, there are many domestic CNC ring rolling machine manufacturers, but selecting a high-quality vertical CNC ring rolling machine manufacturer often requires […]
The ring rolling machine is mainly used to process high-quality large seamless rings. Compared with traditional casting, it has excellent process characteristics such as energy saving, high efficiency and higher material utilization rate. The strength, wear resistance and service life of workpiece are greatly improved. Most small and medium-sized ring rolling machines are adopted a […]
Ring rolling is a specialized type of metal forming operation, which reduces the thickness (cross section) and enlarges the diameter (circumference) of the work piece by a squeezing action as it passes between two rotating rollers. Rolling (metal working), In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of […]
We want to produce small bearing ring by ourselves, what equipments do we need? Can you suggest machines for us? Customers usually asked this for us. This is the Ring Rolling Progress Diagram We suggest the following machines: 350KW Induction Furnace, 2500KN Power Press, 1600KN Power Press, 160E Ring Rolling Machine 350KW Induction Furnace […]
Problems of ring rolling machine should be comprehensively analyzed: The ring rolling temperature does not reach the forging temperature of material. The ring rolling ratio is too large, which exceeds the deformation capacity of material. The supplier’s steel may have problems.
How to choose tonnage of forging press The calculation method is as follows: 1) P=p/q=(64 ～ 73) F/q, where P — tonnage of screw press (KN); P – deformation force required for free forging (KN); F – developed area of steel casting connected with burrs (cm2); (64 ～ 73) – complex steel casting index is […]
Ring rolling (also known as ring expanding, drilling, ring rolled) is a plastic manufacturing process that relies on ring rolling machine (also known as ring mill, hot continuous ring rolling, hole expanding machine) to cause continuous plastic deformation of ring, so as to complete wall thickness reduction, diameter expansion, and cross section contour forming. This […]
Code Meaning (Q, Y, D, E ,F ) in Ring Rolling Machine Type and Advantages Q means pneumatic type ring rolling machine Y means hydraulic type ring rolling machine D means common narrow-middle type ring rolling machine E means large width type ring rolling machine F means super large width type ring rolling machine […]
The following points are main common troubles during using Ring Rolling Machine, and Solving Way for them: No action of main oil cylinder, No pressure of hydraulic parameter If the hydraulic oil is not filled out, check the oil pump If the adjusting pressure is no action, clean the adjusting valve If there is […]
Overview Bearing rings are important part of rolling bearing, its weight is about 60%-70% of the total bearing. Bearing races have forging, cold extrusion, warm extrusion, pipe and bar, etc., types, forged bearing rings are occupied 85% of the total number of blank rings. It has the following types of bearings: Deep groove ball bearings, […]
