A kind of chrome-plating processing technology on the production surface of metal piston ring

Abstract

The invention relates to a chrome-plating process for the production surface of a metal piston ring. The chrome-plated process for the production surface of a metal piston ring adopts the following chrome-plated process device for the piston ring surface. , an electroplating hanger, a rotating mechanism, the liquid immersion device includes a rotating rod, a liquid immersion motor, a bearing seat, a rotating disc, and a fixed element, and the chrome plating process for the production of piston rings using a piston ring surface chrome plating processing device includes the following steps : S1, electroplating preparation; S2, hanger installation; S3, uniform electroplating; S4, cyclic electroplating. The present invention can complete the continuous surface chrome plating of metal piston ring production, solves the clamping and fixing of the piston ring by the existing clamping tool, so that the electroplating operation cannot be completed on the surface of the clamping part of the piston ring during electroplating, and there is a dead angle of electroplating, so that the piston The uneven distribution of electroplating layer on the ring surface affects the quality of piston ring products and other issues.

Description

technical field [0001] The invention relates to the technical field of chrome plating of piston rings, in particular to a chrome plating process for the production surface of metal piston rings. Background technique [0002] Piston rings are metal rings used to embed in piston grooves. Piston rings are divided into two types: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. [0003] The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove. The piston ring is the core component inside the fuel engine, and it completes the sealing of...

Problems solved by technology

[0005] 1. Clamping electroplating refers to manually clamping and fixing the metal piston ring with a clamp, and then immersing it in the electroplating solution. During the electroplating operation, due to the clamping and fixing of the piston ring by the clamping tool, the clamping position of the piston ring The electroplating operation cannot be completed on the surface during electroplating, and there are electroplating dead angles, which make the electroplating layer on the surface of the piston ring unevenly distributed, thus affecting the quality of the piston ring product;

[0006] 2. Immersion electroplating refers to manually putting the piston rings to be electroplated into the electroplating pool filled with electroplating solution, and then performing electroplating operations. In this way, the piston rings will sink and fall on the bottom of the electroplating pool. This stacking plating method makes The surface of the piston ring cannot be completely and evenly contacted with the electroplating solution, so that the thickness of the electroplating layer of the piston ring is uneven and prone to electroplating dead ends, the electroplating effect is poor, and it is not convenient for centralized collection after the electroplating is completed
