Rolling Machine The Principle Of Processing

  Rolling Machine Rod rolling machine (Rod rolling machine) refers to the processing of light rod machine. Pole (also known as the piston rod, etc.) generally in the motor, cylinder, cylinder, valves, linear bearings, pumping machines and other applications.

   Rolling Machine The basic characteristics of the rod is the slender shaft processing, the processing of difficult, coaxial degree, straightness, finish, abrasion resistance requirements, has been troubled by the processing staff problems.

The use of rolling processing, due to surface residual surface pressure on the surface, contribute to the surface of small cracks in the closed, hinder the erosion of the expansion. Thereby improving the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thereby increasing the fatigue strength of the cylinder rod. By rolling, the rolling surface forms a layer of cold hardened layer, reducing the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the polished rod surface, while avoiding the burn caused by grinding. After rolling, the surface roughness value decreases, can improve the compatibility properties. At the same time, reduce the light rod piston movement of the seal or seal on the friction damage, improve the overall service life of the parts. After rolling, the surface roughness of the rod is reduced from Ra0.2 ~ 6.3um to Ra0.1 ~ 0.8um, and the surface hardness of the rod is increased by about 30%, and the fatigue strength of the rod is increased by 25%. Cylinder life, increased by 2 to 3 times, rolling process than the grinding process efficiency increased by about 15 times.

   Rolling Machine Mirror Dr. Roller rolling effect Rolling technology: is a kind of pressure finishing, is the use of metal at room temperature in the cold plasticity characteristics, the use of rolling tools on the workpiece surface to exert a certain pressure, so that the workpiece surface metal plastic flow, fill Into the original residual low valleys, and to achieve the workpiece surface roughness decreased. Due to the rolling surface of the metal plastic deformation, so that the surface layer of cold and hardened grain and thinning to form a dense fibrous, and the formation of residual stress layer, hardness and strength, thereby improving the workpiece surface wear resistance, corrosion resistance Sexuality and coherence. Rolling is a non-cutting plastic processing method.
