Abstract
The invention discloses a trapezoidal piston ring processing method. The trapezoidal piston ring processing method includes steps of 1) casting; 2) shaping monomer mechanically; roughly grinding two end faces; 4) thermally treating; 5) finely grinding two end faces; 6) checking the semi-products; 7) turning the outer circle by molding; (8) milling and opening; 9) roughly turning the inner circle; 10) finely turning the outer circle; 11) finely turning the inner circle; 12) chrome plating; 13) turning the trapezoidal surface; 14) grinding the trapezoidal surface. The trapezoidal piston ring processing method is simple, many repetitive procedures are omitted, and work efficiency is improved.
Description
Technical field
The processing method that the present invention relates to a kind of keystone-type piston ring.
Background technology
Piston ring is the important consumable accessory in internal combustion engine, and production lot is very big, well imagines, it is necessary to highly-specialised, organizes straight-lined manufacturing production line.
Piston ring straight-lined manufacturing has features: 1 place of working is highly specialized.Each place of working has been fixed together or a few procedure, and every one procedure is all in fixing place of working processing.It is processed as piston ring corase grind both ends of the surface are unified in corase grind group；2 products are moved by unidirectional transit route on streamline, production process has good seriality, and piston ring one-way movement is moved route and is: roughly grind → deoil → heat treatment → fine grinding → deoil → semi-finished product inspection → cutting firing line → surface process → finished product inspection → combo warehouse-in.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide the processing method of a kind of keystone-type piston ring, and this processing method technique is simple, eliminates a lot of repeatability operation, improves work efficiency.
For achieving the above object, the processing method that the invention provides a kind of keystone-type piston ring, comprise the steps: 1) casting；2) machinery sizing monomer；3) corase grind both ends of the surface；4) heat treatment；5) fine grinding both ends of the surface；6) inspection of semifinished product；7) pattern turning；8) milling opening；9) rough turn inner circle；10) fine turning outer circle；11) thin boring；12) chromium plating；13) car tread；14) mill tread.
The invention has the beneficial effects as follows: the present invention improves working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
Detailed description of the invention
The processing method that the invention provides a kind of keystone-type piston ring, comprises the steps: 1) casting；2) machinery sizing monomer；3) corase grind both ends of the surface；4) heat treatment；5) fine grinding both ends of the surface；6) inspection of semifinished product；7) pattern turning；8) milling opening；9) rough turn inner circle；10) fine turning outer circle；11) thin boring；12) chromium plating；13) car tread；14) mill tread.
The present invention improves working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
