Rolling tool principle

Rolling technology (? Trundle？ Processing)?

Rolling principle and effect The main body of rolling technology is the rolling knife, and different processing surfaces and requirements require different rolling knives. It is a chip-free machining, which uses the plastic deformation of metal at room temperature to flatten the micro-roughness of the workpiece surface, thus achieving the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the purpose of dressing and strengthening at the same time, which is impossible for grinding.

No matter what processing method is adopted, there will always be tiny uneven knife marks on the surface of the parts, and there will be staggered peaks and valleys, which provides a prerequisite for the implementation of the rolling process.

Working principle of rolling technology: it is a kind of pressure finishing, which uses the cold plasticity of metal at room temperature and applies a certain pressure on the surface of workpiece by rolling tools to make the metal on the surface of workpiece flow plastically and fill it into the original residual low groove, thus reducing the roughness value of the surface of workpiece. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened, the grains are refined, a dense fibrous structure is formed, and a residual stress layer is formed, which improves the hardness and strength, thus improving the wear resistance, corrosion resistance and adhesion of the workpiece surface. Rolling is a plastic processing method without cutting. More technology can be consulted: Ningbo Jingheng Kaixiang Machinery Co., Ltd.?

The rolling technology is safe and convenient, and the precision can be accurately controlled. What are its advantages?

1, improve the surface roughness, and the roughness can basically reach Ra≤0.08um?

2. The roundness is correct, and the ellipticity can be ≤ 0.01mm.. ?

3, improve the surface hardness, eliminate stress and deformation, and improve the hardness by HV ≥ 40.

4. Residual stress layer exists after machining, and the fatigue strength is improved by 30%. ?

5, improve the quality of cooperation, reduce wear and prolong the service life of parts, but reduce the processing cost of parts.

□? Application advantages?

High efficiency-the surface can be machined to the required surface accuracy in a few seconds, and the efficiency is 5-20 times that of grinding and 10-50 times that of turning.

High-quality mirror accuracy of Ra0.05-0. 1um can be achieved by one feed; Surface extrusion hardening improves wear resistance and fatigue strength; The plastic deformation of the surface is eliminated, and the dimensional accuracy can remain stable for a relatively long time.

Economy-large equipment does not need capital, land occupation, power consumption, waste residue treatment and other inputs; Without the input of professional and technical personnel. ?

Convenient-it can be clamped on any rotating and feeding equipment, and the mirror surface accuracy can be machined without professional training.

Environmental protection-no chip (environmental protection) and low energy consumption. ?

Non-safety cutting hob has no blade.
