Abstract

The invention relates to a forging and pressing thermal treatment integration device for additive manufacturing. The device comprises a heating component for heating a sedimentary layer, a forging andpressing component for forging the heating region, and a temperature measuring component for detecting the temperature of the heating region; the device further comprises a control component electrically linked to the heating component, the forging and pressing component and the temperature measuring component separately. The compactness of the additive manufacturing metal material can be greatlyimproved, the internal stress is eliminated, defects are reduced, the internal grain structure is controlled and improved, and therefore the mechanical performance of the material is improved; in addition, the technology has the high operability, the forging time and temperature can be controlled according to the technological requirement, and the device is applicable to more 3D printing modes.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, in particular to a forging heat treatment integrated device for additive manufacturing, in particular to a forging heat treatment device used in the metal additive manufacturing process. Background technique [0002] Modern industrial high-end equipment such as aviation, aerospace, ships, electric power and petrochemicals is rapidly developing towards large-scale, high-parameter, high-reliability under extremely harsh conditions, and long-life service. The size of metal components is getting bigger and bigger, the structure is getting more and more complex, and the performance requirements are getting higher and higher. The corresponding manufacturing technology requirements are getting higher and higher, and the challenges are becoming more and more serious. Using traditional manufacturing technologies such as casting, forging and machining to produce the above-mentioned large-sca...
