Abstract

The invention discloses a production process of an anti-corrosion and easy-to-dissipate hydraulic cylinder, and relates to the field of hydraulic cylinders. The inner wall of the hydraulic cylinder is coated with an anti-corrosion and easy-to-dissipate ceramic coating. The steps include: S1. Configuring the ceramic coating, S2. Ceramic paint is applied on the inner wall of the hydraulic cylinder, S3. drying the hydraulic cylinder coated with ceramic paint, and S4 sintering the hydraulic cylinder; the ceramic paint components include: 15-30 parts of inorganic binder, 7-12 parts of filler 60-75 parts of ceramic powder, 3-12 parts of pigment, 1-5 parts of nano oxide, 5-12 parts of silicon dioxide. The invention solves the problem that the inner wall of the hydraulic cylinder is easily corroded and peeled off, which affects the service life of the hydraulic cylinder.

Description

technical field [0001] The invention belongs to the field of hydraulic cylinders, and in particular relates to a production process of an anti-corrosion and easy-to-radiate hydraulic cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). [0003] As the main components of hydraulic cylinders, mining single pillars, hydraulic supports, gun barrels and other products, the processing quality of cylinder barrels directly affects the life and reliability of the entire product. The processing requirements of the cylinder barrel are high, and the inner surface roughness requirement is Ra0.4~0.8&um, and the requirements for coaxiality and wear resistance are strict. The basic feature of the cylinder is deep hole processing, which has always troubled the processing personnel. [0004] Rolling processing is used, because the surface layer ha...
