Abstract

FIELD: manufacture of piston rings for engines. SUBSTANCE: method comprises steps of flattening piston rings, then subjecting them to shot blasting at inner and outer sides for performing them and making stressed layer with microcraters. EFFECT: enhanced wear resistance and elasticity of piston rings. 5 dwg

Description

Изобретение относится к области изготовления поршневых колец двигателей. The invention relates to the manufacture of piston rings of engines.

Известен способ изготовления поршневых колец, в процессе которого производят плющение (пат. FR 2656560, B 23 P 15/06, 1991 г.). A known method of manufacturing piston rings, in the process of which they perform conditioning (US Pat. FR 2656560, B 23 P 15/06, 1991).

В предлагаемом изобретении предусмотрено повышение износостойкости колец. Способ предполагает повышение износостойкости после их плющения. Кольца дополнительно подвергают дробеструйной обработке с внутренней и наружной сторон с образованием на них наклепа и напряженного состояния с микролунками. In the present invention provides an increase in wear resistance of the rings. The method involves increasing wear resistance after conditioning. The rings are additionally subjected to bead-blasting from the inner and outer sides with the formation of hardening and stress state with microwells on them.

Изобретение поясняется чертежами, где на фиг. 1, 2 показаны процессы дробеструйной обработки колец, соответственно с наружной и внутренней сторон. Обработку предварительно подвергнутых плющению колец производят с помощью дроби 11, которая может подаваться как через сопло 6, установленное на патрубок 5, так и через полую обойму 7, по которой подают дробь в сопла 9, расположенные симметрично по внутреннему кольцу обоймы, чем создается дробефакельный кольцевой инструмент, обеспечивающий обработку поверхности колец 10 (фиг. 1). The invention is illustrated by drawings, where in FIG. 1, 2 shows the processes of shot peening of rings, respectively, from the outer and inner sides. The pre-rolled rings are processed using a shot 11, which can be supplied both through a nozzle 6 mounted on the nozzle 5, and through a hollow holder 7, through which the shot is fed into nozzles 9 located symmetrically along the inner ring of the holder, which creates a shot-ring ring a tool that provides surface treatment of the rings 10 (Fig. 1).

Дробеструйная суспензия подается в один или несколько патрубков 8, подсоединенных к обойме. Для обработки наружных поверхностей колец их собирают в пакет с помощью устройства, состоящего из корпуса 1 (фиг. 2), шайбы 1', колец 2, насаженных на корпус, нижней шайбы 3 и скрепляющей кольца в один пакет гайки 4. Shot blasting suspension is fed into one or more nozzles 8 connected to the cage. To process the outer surfaces of the rings, they are collected in a package using a device consisting of a housing 1 (Fig. 2), a washer 1 ', rings 2, mounted on the housing, a lower washer 3 and a fastening ring into one nut package 4.

Корпус в верхней части имеет крышку 13, которая закреплена с помощью шестигранника 14. В нижней части устройства предусмотрены отверстия 12 для выпуска воздушно-газовой среды. The housing in the upper part has a cover 13, which is fixed using a hexagon 14. In the lower part of the device, openings 12 are provided for discharging the air-gas medium.

Обработку колец с внутренней стороны (фиг. 1) производят обоймой 7, насаженной на сопло 6 или сопло 5. The processing of the rings from the inside (Fig. 1) produce a clip 7, mounted on the nozzle 6 or nozzle 5.

В качестве дроби могут использоваться гранулы дроби пиромидальной формы, в виде кубиков или шариков, при этом использование дроби в виде шариков обеспечивает получение более высоких показателей. As a fraction, granules of a pyramidal shape can be used, in the form of cubes or balls, while using a fraction in the form of balls provides higher performance.

На фиг. 3, 4, 5 показаны примеры образуемых на обрабатываемой поверхности лунок различной глубины. In FIG. 3, 4, 5 show examples of holes formed on the treated surface of different depths.

В результате такой обработки повышается износостойкость поршневых колец и их упругость. As a result of this treatment, the wear resistance of the piston rings and their elasticity are increased.
