Abstract

The invention discloses an acid-resisting anticorrosive hydraulic cylinder production process, which relates to the field of hydraulic cylinders. An anticorrosive ceramic coating easy to cool coats aninner wall of a hydraulic cylinder. The production process comprises the following steps: S1, preparing the ceramic coating; S2, coating the inner wall of the hydraulic cylinder with the ceramic coating; S3, drying the hydraulic cylinder coated with the ceramic coating; S4, sintering the hydraulic cylinder, wherein the ceramic coating is prepared from the following coating raw materials added inthe step S1 in parts by weight: 10 to 20 parts of inorganic adhesive, 10 to 15 parts of filler, 80 to 95 parts of ceramic powder, 15 to 20 parts of clay, 3 to 12 parts of pigment, 1 to 5 parts of nanometer oxide, and 1 to 5 parts of silicon carbide. The acid-resisting anticorrosive hydraulic cylinder production process provided by the invention solves the problems that the inner wall of the hydraulic cylinder is easy to corrode and fall off, and the service life of the hydraulic cylinder is affected.

Description

technical field [0001] The invention belongs to the field of hydraulic cylinders, and in particular relates to an acid-resistant and anti-corrosion hydraulic cylinder production process. 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 has resi...
