D51Y Multi-function Ring Rolling Machine

For greater reaming ratio ring, due to the thrust roller is fixed during shaping, when it expanded to a certain extent, adjust the position of the thrust rollers , heat second time or more times. For more complex shape and smaller expansion ratio forgings (especially ring with deep grooves, such as bilateral flange, double gear and bilateral supporting wheels, all kinds of ball valve linker, etc.) ordinary ring rolling machine can’t do it. Multi-point radial ring rolling machine is developed to meet the requirement of this demand. When the ring inner diameter is expanded to touch three ring rolling wheel, continue to put pressure, which will limit the expansion of the inner diameter of the ring, at the same time, on the ring outer periphery of the metal will be rotated and squeezed, so that it fills the mold cavities to form smaller rolling ratio and complex shape ring . To facilitate the loading and unloading work, smaller rolling wheels on both side need to rely on that small rolling wheel cylinder push a lever pivoted and leave the work place. Multi-point radial ring rolling machine can produce this special kind of rings and enlarge the ordinary ring rolling machine function to finish the work that ordinary grind ring ring machine can not be done, but there are some problems: it is not convenient to adjust ring rolling machine when replace ring types when the species is not very convenient to adjust the device. To this end, multi-function ring rolling machine is developed.
