The vertical ring-tying machine has small tonnage and large processing range. The rolling ring forming process is the accumulation of continuous small deformations under local pressure. The contact area between the workpiece and the mold is small, so the required deformation force is small and the equipment tonnage is small.
The material utilization rate is high, the cross-sectional shape of the ring rolling is closer to the finished product, and the machining allowance is small.
The product quality is good. The metal fibers of the rolled ring are continuously distributed along the circumferential direction, which is suitable for the stress and wear of the parts during use. In most cases, the internal structure of rolled rings is dense, the grains are fine, and the comprehensive mechanical properties are significantly higher than those of rings processed by other methods.
Our vertical ring tying machine has good conditions, high productivity, ring rolling similar to static pressure rolling, low noise, easy to operate, high degree of mechanization and automation, greatly reducing the labor intensity of workers,
Our vertical ring tying machines have low production costs. It has low material consumption, low energy consumption, low overall production cost and good economic benefits.
In the vertical ring rolling machine, the ring blank whose temperature meets the requirements is placed on the rolling roller. The rotating rolling wheel moves downward under the force of the oil cylinder. After contacting the ring blank, the ring blank begins to deform. At this time, the ring blank and the rolling roller rotate under the action of friction, the ring blank is compressed, the wall thickness gradually becomes thinner, the metal extends along the tangential direction (there is also a small amount of broadening in the axial direction), and the extension deformation of the ring is in a free state. When the outer diameter of the ring comes into contact with the fixed thrust roller, the reaction force of the thrust roller increases the outer diameter of the ring and at the same time produces bending deformation, pushing the geometric center of the ring blank to the left of the center line of the machine, causing the rolling The expansion process proceeds smoothly. When the outer diameter of the ring blank increases to the pre-adjusted signal roller, the rolling wheel can return upward and the forging is unloaded, completing a working cycle.
