Abstract
The invention discloses a piston ring of a diesel engine, which is made of steel work and manufactured by adopting the following steps: 1, circularly winding the steel work on a special dense winding forming machine to form a shape; 2, processing the circularly-wound and formed steel work with an inner circle and an outer circle on a special machine tool, removing burrs on chamfer angles and manufacturing a semi-finished product; 3, modifying and quenching the semi-finished product, and then carrying out abrasion-resistant treatment such as chromium plating, nitriding, vapor deposition and the like; and 4, milling and then leveling a product with a polished outer circle by adopting a special milling machine or a precision cutting machine, and finally, precisely grinding two ends of the product by adopting a grinding machine with double end faces, removing the burrs and cleaning the product. Therefore, the piston ring of the diesel engine has the advantages of low cost, good abrasion resistance and long service life, thoroughly solves the phenomenon of ring breakage during use, and is applicable to the diesel engine.
Description
Technical field:
The present invention relates to a kind of piston ring of diesel engine component, particularly a kind of diesel engine.
Background technique:
At present, the diesel engine compression ring of China adopts cast iron quality, the abscission ring phenomenon in use very easily occurs, and working life is short.
Summary of the invention:
Purpose of the present invention will provide a kind of increasing the service life exactly, and reduces the piston ring of diesel engine of manufacture cost.
The object of the present invention is achieved like this: a kind of piston ring of diesel engine is characterized in that piston ring is that steel part is made.
An optimum implementation of the present invention is: steel part is a kind of in section wire and the steel band, and section wire is a kind of in trapezoidal, rectangle, the wedge-section wire.
The present invention is realized by following steps:
1), with steel part special use close on molding machine around the circle moulding;
2), will around the circle moulding steel part on special purpose machine tool, cut inside and outside circle, semi-finished product are made in the chamfering deburring;
3), semi-finished product are carried out carry out Wear-resistant Treatment such as chromium plating, nitrogenize, spraying, vapor deposition after modified setting is handled;
4), the product that the cylindrical polishing treatment is good adopts special use to mill mouthful machine or precision gas cutting machine mills a mouthful back smoothing, adopts double-ended grinding machine or form grinding machine correct grinding both ends of the surface at last, deburring, cleaning.
The present invention compares with modern technologies and has the following advantages:
1, because the mechanical strength height of steel, good thermal stability, high elasticity and high impact properties, especially the abscission ring phenomenon that cast-iron piston ring is in use occurred is used from material and is solved.Adopt steel to make the diesel engine compression ring, its supporting plane must carry out surface treatment methods such as chromium plating, nitrogenize, spraying, vapor deposition to improve sliding.
2, adopt steel to make the diesel engine compression ring, saved the casting process of cast iron ring, reduced manufacture cost.The simplest employing profile wire or steel band through moulding, mill mouthful, the machine-tooled method of face grinding, can produce steel diesel engine compression ring, so low cost of manufacture.
Embodiment:
Embodiment 1: be example with the section wire
Round wire is drawn into trapezoidal steel wire, again steel wire is shaped around circle on molding machine in that special use is close, car mill inside and outside circle, chamfering is made semi-finished product, semi-finished product is carried out carrying out in the wear-resisting places such as chromium plating, nitrogenize, spraying, vapor deposition after modified setting is handled, and cylindrical is polished, mouthful machine is milled in the employing special use or precision gas cutting machine mills a mouthful back smoothing, adopt double-ended grinding machine or form grinding machine correct grinding both ends of the surface at last, deburring, cleaning can manufacture the steel piston ring of diesel engine.
During use, piston ring is packed in the diesel engine according to conventional assembly technology, can use.
Embodiment 2: be example with the steel band
With steel band special use close on molding machine around the circle moulding, car mill inside and outside circle, chamfering, semi-finished product are carried out carrying out Wear-resistant Treatment such as chromium plating, nitrogenize, spraying, vapor deposition after modified setting is handled, and with the cylindrical polishing treatment, mouthful machine is milled in the employing special use or precision gas cutting machine mills a mouthful back smoothing.Adopt double-ended grinding machine or moulding mill correct grinding both ends of the surface at last, deburring, cleaning can produce the steel piston ring of diesel engine.
During use, piston ring is packed in the diesel engine according to conventional assembly technology, can use.
