Embodiment 1

[0073] Embodiment 1: Select and process the oil cylinder substrates to be processed and place them on one side of the rotary table in turn. The diameter of the rotary table is set to 180 cm to 220 cm, and the upper middle position bolt is equipped with a four-jaw single-action chuck. There are also screws installed with handles around the position, manually wipe the table surface of the rotary table with a sponge, install the supersonic spraying equipment and the dust recovery device on the outer side of the rotary table with bolts, and use the nozzle to spray the bonded bottom layer on the cylinder base, Carry out turning on the base body of the oil cylinder, and ensure that the thickness of the base body of the oil cylinder is uniform. A layer of roughening agent with a thickness of 0.1mm to 0.3mm. After the application is completed, wait for the oil cylinder base to be clamped at the upper middle of the rotary table, so that the rotary table can be manually rotated and insta...

Abstract

The invention provides a tungsten carbide wear-resistant coating spraying process for an oil cylinder, and belongs to the field of coating spraying. The tungsten carbide wear-resistant coating spraying process for the oil cylinder comprises the specific steps that 1, preparation is made; 2, the oil cylinder is sprayed with a bonding bottom layer; 3, a bottom layer pasted to the oil cylinder is removed; 4, an oil cylinder base is purified, and roughening treatment is carried out, wherein (1, the surface of the oil cylinder base is wiped completely, and (2, the outer side of the oil cylinder base is subjected to roughening treatment; 5, the oil cylinder base is subjected to rotary spraying dust removal, wherein (1, the oil cylinder is placed on a rotary table, (2, the rotary table is manually rotated, (3, a supersonic spraying device is used for spraying tungsten carbide powder, and (4, a dust recovery device is opened for dust removal in the spraying process; and 6, storage is completed. The tungsten carbide wear-resistant coating spraying process is mature in technology, can prevent dust from falling to the outside, improves the environmental protection effect, is high in work efficiency and can increase the hardness of an entire cylinder base.

Description

technical field [0001] The invention belongs to the technical field of coating spraying, in particular to a tungsten carbide wear-resistant coating spraying process for an oil 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). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Buffers and exhausts are application sp...
