Abstract

The invention belongs to the field of additive manufacturing, and in particular relates to an arc additive device and method for controlling stress deformation by using vibration aging. Including welding torch, substrate, welding workbench, electromagnetic fixture and vibrator; electromagnetic fixture is used to fix the substrate on the welding workbench, and the vibrator is connected to the substrate for vibration during the arc additive process and after additive Vibration aging treatment of components. After each layer of additive manufacturing and after the overall additive manufacturing is completed, the components are subjected to vibration aging treatment to reduce the residual stress in the components and control stress deformation; at the same time, the vibration sensor is used to detect the vibration frequency in real time and feed back to the vibration control device to achieve real-time Control the vibration frequency; on this basis, use the electromagnetic clamp that can quickly control the switch to fix the substrate, which can greatly reduce the time for loading and unloading the clamp, and effectively improve the efficiency of vibration aging. The invention can effectively control the stress deformation in the arc additive material and improve the quality of the additive component.

Description

Technical field [0001] The present invention belongs to the field of addition, and specifically, a arc adding apparatus and method using vibration aging control stress deformation. Background technique [0002] The arc manufacturing is a heat source based on the welding arc. The CAD model established according to the part three-dimensional entity is subjected to a layered slice, and the advanced digital manufacturing technique of the required part is manufactured by a certain forming path. It has the advantages of high forming efficiency, low manufacturing cost, short production cycle, high material utilization, and wide materials available. [0003] However, in the arc additive process, there is a huge temperature gradient between the components during the arc additive, the substrate and the deposition layer, and the deposition layers, and the metal melt is not uniform, and the residual stress and deformation will inevitably produce residual stress and deformation. It has greatl...
