Isothermal forging die for complex aviation thin-walled part

Abstract

An isothermal forging die for a complex aviation thin-walled part comprises an upper padding plate, an upper die seat, an upper die sleeve, an upper die, an L-shaped insulation barrel, a lower die seat, a lower die sleeve, a lower die, a lower insulation barrel, an upper heating bar and a lower heating bar. Due to the number of the heating bars and the designed layout, the constant temperature of the die and a forging stock can be guaranteed, and the temperature of the forging stock in the forging process can be always kept within the best forging temperature range. The L-shaped insulation barrel is adopted, heat loss can be reduced, and it is ensured that the temperature of the die and the temperature of the forging stock are the same. The isothermal forging die for the complex aviation thin-walled part is simple and strong in universality.

Description

Technical field: [0001] The invention relates to an isothermal forging die device for complex aviation die forgings, in particular to the isothermal forging of aviation thin-walled parts, and belongs to the technical field of thermal processing. Background technique: [0002] With the rapid development of the aviation industry, the components tend to be large and integrated, thin-walled, lightweight, and complex in shape, and must meet the requirements of high performance and low cost. As an important part of the space shuttle, large and complex parts with high-reinforcement and thin-wall are widely used in the aviation industry. At present, space shuttles are developing in the direction of high performance and long life, and their performance requirements for large and complex parts with high ribs and thin walls are also gradually increasing. However, due to the complex structure of high-reinforced thin-walled large and complex parts, defects such as incomplete filling and...

AI Technical Summary

Problems solved by technology

However, during the forging process, the upper and lower insulation barrels cannot be closed, so that the mold and the forging blank are in contact with the outside air, resulting in heat loss, and it is impossible to ensure that the mold and forging blank are at a constant temperature during the forging process

At the same time, due to the inevitable heat loss in the isothermal forging process, the temperature of the forging billet decreases, so that the temperature of the forging billet cannot always be within the optimum forging temperature range of the material, thereby deteriorating the forming ability of the material and making it impossible to form high-quality products. quality forgings
