Description

Существующий способ индивидуальной отливки поршневых колец дл  автотракторных, авиационных и танковых двигателей обладает тем недостатком, что область замка, будучи св зана со всей литниковой системой, остывает медленнее, чем остальна  часть кольца, что приводит к ухудшению качества кольца.The existing method of individual casting of piston rings for autotractor, aviation and tank engines has the disadvantage that the lock area, being associated with the entire sprue system, cools more slowly than the rest of the ring, which leads to a deterioration in the quality of the ring.

Кроме того, при отламывании кольца остаютс  заусенцы, что требует дополнительной механической обработки каждого кольца. И, наконец, при вырезке замка значительна  часть металла уходит в стружку.In addition, burrs remain when the ring is broken off, which requires additional machining of each ring. And, finally, when cutting the lock, a significant part of the metal goes into the chips.

В предлагаемом способе отливки поршневых колец эти недостатки устранены посредством уменьшени  сечени  кольца в месте соединени  его с питателем, что создает равномерное ускоренное охлаждение всего кольца и устранение заусенцев при отламывании питател .In the proposed method of casting piston rings, these disadvantages are eliminated by reducing the cross section of the ring at the point of its connection with the feeder, which creates a uniform accelerated cooling of the entire ring and eliminating burrs when breaking the feeder.

Дл  уменьшени  сечени  кольца в месте соединени  его с питателем (в месте вырезки замка) делаетс  выемка, идуиаа  от середины торцовой части кольца до уровн  питател , шириной, равной ширине питател , не превышающей размеров замка.To reduce the cross section of the ring at the point of its connection with the feeder (at the point of the lock cutting), a recess is made, going from the middle of the ring end to the level of the feeder, the width equal to the width of the feeder not exceeding the dimensions of the lock.

Предмет изобретени Subject invention

Способ отливки поршневых колец при 1шдивидуальной их формовке , отличающийс  тем, что питатель литниковой системы кольца входит в тело кольца в месте выреза замка кольца и образует уступ, с целью сокращени  расхода металла, обеспечени  чистого отлома кольца от питател  и сокращени  объема обнаждачиванн .The method of casting piston rings when they are individually molded, characterized in that the feeder of the gating system of the ring enters the ring body at the site of the notch of the ring lock and forms a ledge, in order to reduce metal consumption, ensure clean breakage of the ring from the feeder and reduce the volume of the exposed.
