Abstract

The present invention provides what appears to be an ultrasonic impact forging device. It includes an ultrasonic vibration body and a forged body. The forged body includes an upper interface section, a middle cooling section, a side pressure control section, and a bottom pulse forging mechanism. The first side pressure control section is connected to the negative electrode conductor. The first side pressure control section includes The pressure control box, the resonance plate and the shock-absorbing plate, the pressure control box contains a counterweight mechanism, and the lower end of the counterweight mechanism is connected with the negative electrode conductor; the second side pressure control section is connected with the positive electrode conductor, and the second side pressure control The segment also includes a pressure control box and a shock absorber. The lower end of the counterweight mechanism of the pressure control box is connected to the positive electrode conductor. The negative electrode conductor, the positive electrode conductor, the forging head and the temperature sensor constitute the bottom pulse forging mechanism. As an auxiliary equipment for additive manufacturing, the present invention completes the forging of the additive structure in the low-strength state of the alloy, and realizes the optimization of the structure and performance of the additive and the regulation of the internal stress.

Description

technical field [0001] The invention relates to a forging device, in particular to a micro forging device used for post-processing of additive manufacturing. Background technique [0002] Additive manufacturing technology is the most potential advanced manufacturing method at present. It uses high-energy processing beam (arc, electron beam, laser beam, etc.) as the heat source, layering the digital data of the three-dimensional model, and then using "point-by-point scanning melting- The processing method of line-by-line scanning overlap and layer-by-layer solidification and accumulation realizes the direct forming of three-dimensional solid parts. In the additive manufacturing process, the interaction time between the high-energy beam and the material (powder or wire) is extremely short. During the layer-by-layer accumulation of the material, the material continues to undergo a violent alternating process of cold and heat, resulting in the molten pool and its adjacent parts....

AI Technical Summary

Problems solved by technology

When forming a multi-component material part with a large volume and complex shape, the intensity of ultrasonic vibration at the bottom of the substrate will gradually weaken, so effective ultrasonic intervention in the entire area of ​​the part cannot be achieved and the improvement effect on stress is limited, which directly affects the ultrasonic vibration-assisted additive at the bottom The effectiveness of the manufacturing method

As a miniaturized auxiliary forging device for additive manufacturing, the ultrasonic impact forging head has a small forging tonnage and is based on the heat-affected zone of a high-energy beam heat source. It is difficult to effectively process high-strength alloys such as nickel-based alloys and high-strength steels.
