Abstract
The invention discloses a method for processing a biased barrel surface of a piston ring. The method comprises the following steps of: grinding a semicircular surface of an external circle, namely grinding the outer surface of the piston ring into the semicircular surface by using a forming grinder and a copying template, wherein the copying template has single section of circular surface adapted with the size of the piston ring to be ground; and fine honing the semicircular surface of the piston ring into the biased barrel surface by using an oblique pressing plate, wherein the vertical speed of a honing rod is 5 to 8 meters per minute, the rotational speed of a turntable is 30 to 40 revolutions per minute, and a honing sleeve is a single helix cylinder sleeve with 4 to 6 heads. The method obviously improves the collapse condition of the lower edge. The external circle outline curve of the improved biased barrel surface is smooth, the circular transition at the junction of the upper and lower barrel surfaces is good, and the junction area of the lower edge and the lower lateral surface basically has no edge defect so that the exertion of the downward oil scraping function of the piston ring of the biased barrel surface is favorable; meanwhile, the roughness of the external circle surface is obviously improved; and the scuffing resistance and the sealing performance of a loader are improved.
Description
Technical field
The present invention relates to a kind of processing method of piston ring, is a kind of piston ring processing method of bucket face partially specifically.
Background technology
The top compression ring excircle configuration of the engine of high load capacity, high explosion pressure generally adopts inclined to one side bucket face form, and existing processing mode is to utilize the pattern form grinder that crushing is become anti-barrel-shaped partially shape, utilize emery wheel that the excircle configuration of ring is machined directly to moulding bucket face partially then, there is following shortcoming in such process:
1, because there is error in the forming process of pattern pen, and the following seamed edge that causes piston ring particularly to inlay ring can't keep sharp-pointed corner angle, as shown in Figure 1, there is the profile depression, influenced its excellent frizing performance; Among Fig. 1, T: go up the bucket face and survey high; B: following barrel of face surveyed high; O: the theoretical high point of inclined to one side bucket face; M: encircle high mid point;
2, the roughness of periphery about Ra0.3～0.4, causes the scuffing of cylinder bore under the boundary condition substantially easily, and the sealing property of periphery is not good yet simultaneously;
3, periphery lustre lacking uniformity, color and luster is fuzzy, and outward appearance and feel are relatively poor;
4, the pattern pen of grinding machine and partially between bucket face die plate, crushing cutter and the emery wheel indirect profile duplication have error owing to the complexity (multi-section circular arc curve) of contour shape, influenced the accuracy of the moulding of inclined to one side barrel of face.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome problems of the prior art, solve and to inlay the ring seamed edge problem of subsiding under the bucket face partially, thereby improve the frizing performance of seamed edge under the bucket face ring partially.
Technical scheme: in order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of piston ring is the processing method of bucket face partially, and it comprises the steps:
(1) cylindrical grinding semicircle cambered surface: utilize moulding mill and pattern template that the semicircle cambered surface is worn in the outside of piston ring; Wherein, described pattern template is the single hop arc surface adaptive with piston ring size to be ground;
(2) utilize the semicircle cambered surface microhoning moulding inclined to one side bucket face of inclined plate with piston ring: top gem of a girdle-pendant bar is speed: 5～8m/min up and down; Rotary speed: 30～40r/min; Honing cover: 4～6 single conchoid cylinder sleeves.
Wherein, in the step (2), described top gem of a girdle-pendant bar speed up and down is 5m/min.
Described grinding fluid is mixed by grounds travel and machinery oil, and the volume ratio of described grounds travel and machinery oil is 1: 10; Described grounds travel is the 1200# grounds travel, and machinery oil is the 32# machinery oil.
Beneficial effect: 1, the present invention make down seamed edge subside situation be improved significantly.Improvement retrodeviates the excircle configuration line smoothing of barrel face, and bucket face junction arc transition is good up and down, and there are not marginal trough substantially in following seamed edge and downside cross-connecting area, help bringing into play the function of the descending frizing of inclined to one side bucket face ring piston ring like this.
2, the periphery roughness is obviously improved:
3, the periphery outward appearance is improved, and existing technology cylindrical is fuzzy to grow dim, and the top gem of a girdle-pendant is incomplete, appearance poor; Cylindrical color and luster uniformity of the present invention, appearance looks elegant.
4, improved installation tension cylinder and sealing property: the piston ring of new technology processing is with on domestic well-known main engine plants state III, the state IV types such as the Yuchai 66000, F3000, J6500 and the tin bavin A series that are widely used in my company and produce, B series, and result of use is good.
