Additive manufacturing technology is a revolutionary manufacturing technology that overturns traditional subtractive manufacturing methods. In particular, metal additive manufacturing, as a revolutionary and advanced manufacturing technology, is widely applied in fields such as aerospace, biomedical, industrial molds, and power energy. At present, the metal additive technology is mainly divided into laser additive and arc additive. Laser additive has the advantages of good molding effect and high precision and the like, but it produces smaller workpieces and has slower molding speed, making it suitable primarily for manufacturing more precise workpieces. The arc additive manufacturing technology is a process in which the wire is melted by an arc, and the molten metal is stacked layer by layer according to the three-dimensional model of the product, and solidified to form the metal part. The arc additive manufacturing technology can realize the manufacturing of large-sized workpieces, and its manufacturing speed is much faster than that of laser additive manufacturing. However, the manufacturing apparatus used in arc additive manufacturing technology has low precision, resulting in large surface roughness of the parts. Additionally, the heat input in the manufacturing process is high, leading to significant processing stress in the products and making them prone to cracking and other defects.
On this basis, embodiments of the present disclosure provide an arc additive apparatus and method, and a storage medium. The arc additive apparatus provided in the embodiments of the present disclosure adds a corresponding ultrasonic field to the additive process through an additional ultrasonic generating device, thereby achieving improvements in the additive process.
The embodiments of the present disclosure will be further described below with reference to the drawings.
Referring to
It should be noted that the molten pool refers to the part that is melted into a pool shape due to the heat of the welding arc generated by the additive welding gun 110. The liquid metal part with a certain geometric shape formed on the weldment during welding is called the molten pool.
It should be noted that under the heat of the arc generated by the additive welding gun 110, the droplet-like liquid metal formed by melting the end of the wire is called a droplet, and the process of the droplet transferred to the molten pool through the arc space is called droplet transfer.
It could be understood that, referring to
It should be noted that the ultrasonic generator can convert an electric supply into a high-frequency alternating current signal that matches the ultrasonic transducer, and drive the ultrasonic transducer to work. The bypass ultrasonic generator 121 can control the operation of the first ultrasonic transducer 122 and the second ultrasonic transducer, and the first ultrasonic transducer 122 and the second ultrasonic transducer 123 are connected in parallel. The first ultrasonic transducer 122 and the second ultrasonic transducer 123 have the same working state.
It should be noted that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 are arranged on opposite sides of the additive welding gun 110. Compared with the arrangement of a single ultrasonic transducer, according to the arrangement of two opposite ultrasonic transducers, the ultrasonic waves emitted thereby can reach the melting point of the wire from multiple directions or angles, and the ultrasonic energy is stronger, which is beneficial to the regulation of droplet transfer of the wire.
It should be noted that in order to more accurately regulate the droplet transfer of the wire, the first ultrasonic transducer 122 and the second ultrasonic transducer 123 are symmetrically arranged on both sides of the additive welding gun 110, and the distances, angles, etc. between the ultrasonic transducers and the additive welding gun 110 are the same.
It should be noted that the bypass ultrasonic device 120 drives the first ultrasonic transducer 122 and the second ultrasonic transducer 123 to work through the bypass ultrasonic generator 121, so that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 emits ultrasonic waves to the melting point of the wire to form the ultrasonic field, allowing them to regulate the droplet transfer of the wire, further enhancing the stability in the additive welding process and improving the additive efficiency and additive quality. Moreover, part of the ultrasonic waves emitted by the first ultrasonic transducer 122 and the second ultrasonic transducer 123 will enter the molten pool, and the ultrasonic transducers can cooperate with the bottom ultrasonic device 130 to optimize the workpiece 150 in the additive process. Compared with a single bottom ultrasonic device 130, the bypass ultrasonic device 120 and the bottom ultrasonic device 130 cooperate to expedite elimination of bubbles in the molten pool, which reduces the time of additive welding, and further improves the additive efficiency.
It can be understood that, referring to
It should be noted that the arrangement of the amplitude transformers is conducive to the gathering and emission of ultrasonic energy of the ultrasonic waves emitted by the ultrasonic transducers, and the transmitting ends of the amplitude transformers are concave arc surfaces, which is more conducive to the gathering and emission of ultrasonic energy.
It should be noted that the ultrasonic waves emitted by the first ultrasonic transducer 122 are gathered by the first amplitude transformer 124 and emitted to the melting point of the wire, and the ultrasonic waves emitted by the second ultrasonic transducer are gathered by the second amplitude transformers 125 and emitted to the melting point of the wire, so that the ultrasonic field formed thereby is further enhanced, allowing them to regulate the droplet transfer of the wire, further enhancing the stability in the additive welding process, and improving the additive efficiency and additive quality.
It could be understood that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 are both fixedly connected to the additive welding gun 110 for the workpiece 150.
It should be noted that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 are both fixedly connected to the additive welding gun 110 for the workpiece 150, so that relative positions between the first ultrasonic transducer 122 and the second ultrasonic transducer 123 and the additive welding gun 110 remain unchanged.
It should be noted that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 for the workpiece 150 are both fixedly connected to the additive welding gun 110 for the workpiece 150, so that parameters of the ultrasonic waves emitted by the bypass ultrasonic device 120 at the melting position of the wire remain unchanged, ensuring the stability of the additive welding process, which is conducive to improving the quality of the workpiece 150.
It could be understood that, referring to
It should be noted that at least one third ultrasonic transducer 132 is provided. In practical applications, the workpiece 150 is usually placed on a substrate 154, and the additive welding process is also performed on the substrate 154. The number of the third ultrasonic transducers 132 may be set according to the length of the substrate 154, which is not limited in the embodiments of the present disclosure.
It should be noted that many products require the welding gun to move back and forth to meet their required heights, so that the entire workpiece 150 is located within the ultrasonic field generated by the third ultrasonic transducer, but in case of a plurality of third ultrasonic transducers 132, only the third transducer 132 corresponding to the current melting point of the workpiece 150 may be turned on.
It should be noted that the bottom ultrasonic device 130 drives, through the bottom ultrasonic generator 131, the third ultrasonic transducer 132 to work, so that the third ultrasonic transducer 132 emits ultrasonic waves to perform ultrasonic impact on the workpiece 150. The impact of ultrasounds will stir the molten pool to eliminate bubbles in the molten pool. Moreover, large grains in the solidification process of the molten pool are broken and the weld grains are continuously refined, thereby improving the mechanical properties of the weld, and enhancing the quality of the workpiece 150. Compared with the single bypass ultrasonic device 120, the bottom ultrasonic device 130 has an enhanced stirring effect on the molten pool, making it easier to eliminate the bubbles in the molten pool and break the large grains in the solidification process of the molten pool, further enhancing the quality of the workpiece 150.
It could be understood that, referring to
It should be noted that the wire feeder 152 and the additive welding gun 110 can be connected through the pipeline, and the wire fed by the wire feeder 152 can be accurately transferred below the additive welding gun 110 through the pipeline, so as to facilitate later additive welding. The welding machine 151 mainly controls the waveform of the arc current generated by the additive welding gun 110, and can adjust the peak value of the arc current (the current when the arc current is at its maximum), pulse frequency, peak time, and base current. In addition, the welding machine 151 is further connected to the wire feeder 152, so that the speed at which the wire feeder 152 transmits the wire can be adjusted.
It could be understood that, referring to
It should be noted that the containing device 153 and the additive welding gun 110 may be connected through a gas pipeline. Before the additive welding gun 110 is operated, the containing device 153 is opened and the inert gas in the containing device 153 is transferred to the additive welding gun 110, making the inert gas coat the wire, melted liquid droplets and the molten pool. The continuous delivery of shielding gas from the beginning of welding can reduce the probability of oxidation when the molten pool is cooled, and reduce the probability of structural deterioration and mechanical property degradation.
It should be noted that the containing device 153 may be a gas cylinder.
It could be understood that a frequency range of the ultrasonic waves emitted by the bypass ultrasonic device 120 is 20 kilohertz to 50 kilohertz, and a frequency range of ultrasonic waves emitted by the bottom ultrasonic device 130 is 18 kilohertz to 23 kilohertz.
The arc additive apparatus 100 provided in the embodiments of the present disclosure includes an additive welding gun 110, a bypass ultrasonic device 120, a bottom ultrasonic device, and a control device 140. Before the additive welding gun 110 is operated, the containing device 153 is opened, so that the inert gas in the containing device 153 is transferred to the additive welding gun 110, and the welding machine 151 controls the wire feeder 152 to transfer the wire below the additive welding gun 110. The additive welding gun 110 works to melt the wire to add material to the workpiece 150 to be machined. In the additive process, the bottom ultrasonic device 130 drives the third ultrasonic transducer 132 to work through the bottom ultrasonic generator 131, so that the third ultrasonic transducer 132 emits ultrasonic waves to perform ultrasonic impact on the molten wire on the workpiece 150. The impact of ultrasounds will stir the molten pool, thereby eliminating bubbles in the molten pool. Moreover, large grains in the solidification process of the molten pool will be broken and the weld grains are continuously refined, thereby improving the mechanical properties of the weld, and enhancing the quality of the workpiece 150. The bypass ultrasonic device 120 drives the first ultrasonic transducer 122 and the second ultrasonic transducer 123 to work through the bypass ultrasonic generator 121, so that the first ultrasonic transducer 122 and the second ultrasonic transducer 123 emit ultrasonic waves below the material welding gun 110 to form an ultrasonic field, that is, at the melting point of the wire, so that it can regulate the droplet transfer of the wire, thereby further enhancing the stability in the additive welding process and improving the additive efficiency and additive quality. Furthermore, part of the ultrasonic waves emitted by the first ultrasonic transducer 122 and the second ultrasonic transducer 123 will enter the molten pool and the ultrasonic transducers can cooperate with the bottom ultrasonic device 130 to optimize the workpiece 150 in the additive process, thereby improving the mechanical properties of the weld, and enhancing the quality of the workpiece 150.

A signal transmitting end of the bypass ultrasonic generator 121 is connected to the first ultrasonic transducer 122 and the second ultrasonic transducer 123.
