A kind of cutting structure of ring-dropping machine

Technical field

The invention relates to the technical field of piston rings, and in particular to a ring dropping machine blanking structure.

Background technique

An internal combustion engine is a kind of power machine. It is a heat engine that burns fuel inside the machine and directly converts the heat energy released into power. Piston rings are one of the most critical components in internal combustion engines. Piston rings mainly include gas rings and oil rings according to their functions; gas rings are mainly used to prevent gas leakage and are generally composed of two to three rings. Gas rings can be divided into flat rings, tapered rings, twisted rings, etc. according to their cross-sectional shapes. ; The oil ring has an oil return hole or an equivalent structure, which can scrape engine oil from the cylinder wall. Generally, the oil ring uses one of ordinary oil rings, steel belt combined oil rings or spiral spring combined oil rings.

The quality of the piston ring depends on the quality of the piston ring blank. The existing piston ring blank is manufactured by stacked sand casting. The sand mold has a gate and a plurality of vertically arranged piston ring blank cavities inside. After pouring molten iron into the mouth, the primary product is obtained. The primary product includes a keel and a plurality of piston ring blanks arranged vertically and connected around the keel, as well as a radially protruding sprue head located at the upper end of the keel. After the piston ring blank is separated from the keel, the keel and piston ring blank need to be unloaded and collected separately to facilitate subsequent finishing of the piston ring blank.

In the existing technology, it is generally necessary to manually pick up and collect the keels and piston rings separately. The operation is intensive, inefficient, and highly dangerous.
