Stamp for manufacturing annular parts made of round billets

摘要

The invention relates to equipment for processing metal alloys and pressure, it can be used in aircraft and power engineering in the production mainly of heat-resistant steels and alloys preforms disks and rings of the rotors and compressors and turbines of gas-turbine engine (GTE).;Stamp comprises a matrix and a punch with a hole, on which two shaping surfaces are made, one of which is designed for pre-forming the preform through its distribution, and the second - to its final shaping into the annular part. The punch is made conical surface intended for pre-shaping the preform, made in the form of generatrix of the cone and the surface for the final shaping of preparation - in the form of its base, the punch is equipped with two coaxial shanks, provided on the base of the cone and at its top, and are capable of alternately placing in the hole of the matrix in the preliminary and final shaping parts.;The technical result of the present utility model is to increase the accuracy of the geometrical parameters of manufactured items by ensuring accurate relative position of the punch and die during the whole cycle of forming parts. 4 ZP f ly-1-yl.
