During the operation of the hydraulic Chuck

During the operation of the hydraulic Chuck, after the metal workpiece is rolled on the surface, the surface layer will be reinforced with the ultimate strength and the yield point will be increased. The use performance, wear resistance, corrosion resistance and fatigue strength of the hydraulic Chuck are all increased. There is a clear improvement. After rolling, the hardness can be increased by 15 to 30%, while the wear resistance is increased by 15%.

When the hydraulic Chuck is manufactured, its rolling process can increase the surface roughness from Ra6.3 to Ra2.4 to Ra0.2. And it has high production efficiency, and some workpieces can be completed in minutes or seconds. Rolling process can solve the key problem that some current process methods are not easy to realize. For example, processing of a large Chuck. At the same time, it also applies to the finishing of special holes or the finishing of certain special materials.

The use of a wide range of hydraulic Chucks, such products can be used in all major and small and medium-sized work, regardless of the processing quality, production costs and production efficiency, roll processing is a superior processing method. In some respects, it can completely replace grinding, grinding, honing and other finishing.

Hydraulic Chuck exhaust device adjustment, in the process of operation can first reduce the Chuck working pressure to 0.5-1MPa or so, and then effectively make the piston rod reciprocating, so that you can open the exhaust plug to some extent exhaust . The method of opening is: When the piston reaches the end of the stroke, the vent plug opens at the moment the pressure rises, and closes immediately before starting to return. When the exhaust plug is exhausted, the squeaky sound of the squeaky air is heard, followed by the turbidity of the foamy oil. When the exhausted air is exhausted, the oil is clarified. You can use the naked eye to determine if the exhaust is complete.

Hydraulic Chuck cushion adjustment. In the case of an adjustable cushioning device with the piston in motion, the throttle valve should be placed in a relatively small flow rate, and then the size of the orifice should be gradually adjusted until the requirements are satisfied.
