Problems solved by technology

[0003] As far as the current technology is concerned, the products produced are not satisfactory in terms of coloring flaw detection of forgings, conventional tensile properties, fatigue resistance, high temperature creep properties, etc., especially when the low-fold structure of forgings is completely recrystallized uniform fine grain In terms of technological requirements, it is difficult to achieve the expected effect, resulting in the performance of forgings that cannot meet their application conditions

Abstract

The invention discloses a die forging production process. The die forging production process comprises the steps that the an ingot is heated in the temperature range of 390 DEG C to 410 DEG C for not less than 270min; a mold is heated in the temperature range of 350 DEG C to 450 DEG C for not less than 12h, and is drawn to an embryo by a hydraulic press; the embryo is heated in the temperature range of 390 DEG C to 410 DEG C for not less than 170min; the mold is heated in the temperature range of 350 DEG C to 450 DEG C for not less than 12h; the forging temperature is between 380 DEG C and 400 DEG C, and the final forging temperature is not less than 360 DEG C; and finally the hydraulic press is used to press the embryo mold into a forge piece which is molded once. According to the die forging production process provided by the invention, the temperature and time of each process link are strictly selected, so that the tissues of the forge piece are uniformly recrystallized tissues; the forge piece can meet the requirement of macrostructure fine grain; and problems in the existing technology are solved.

Description

technical field [0001] The invention relates to the field of die forging production, and more specifically, relates to a production process of die forgings. Background technique [0002] Die forgings are important parts inside the supercharger, such as 2618 alloy compressor impeller die forgings, which require high forging technology and comprehensive performance. [0003] As far as the current technology is concerned, the products produced are not satisfactory in terms of coloring flaw detection of forgings, conventional tensile properties, fatigue resistance, high temperature creep properties, etc., especially when the low-fold structure of forgings is completely recrystallized uniform fine grain In terms of technological requirements, it is difficult to achieve the expected effect, resulting in the performance of forgings that cannot meet their application conditions. [0004] Therefore, how to further improve the production process and make forgings meet the requirement...
