Embodiment Construction

[0020] The inventive device such as figure 1 As shown, it includes a clamping device 1 , a plasma arc generating device 2 , and a filamentous metal material 3 . The plasma arc generating device includes an anode head 4 , a cathode head 5 , a plasma torch 6 , a transfer arc 7 and an anode nozzle 8 . The clamping device includes a sleeve head 9 , a mechanical arm 10 and a rotating shaft 11 .

[0021] The working principle of the plasma arc generator 2 is to use the transfer arc 7 as a heat source to obtain a high-energy-density plasma arc. The internal anode nozzle 8 and the cathode plasma torch 6 are respectively connected to the positive and negative electrodes. When working, the gas passes through the plasma torch 6. At this time, the gas It is heated to a higher temperature, and then through the effect of compression, a jet of extremely high temperature and extremely fast plasma is ejected from the anode nozzle 8 to form a plasma arc.

[0022] The clamping device 1 is set ...

Abstract

The invention discloses an efficient dissimilar material plasma arc fused deposition device which comprises a plasma arc generating device and a clamping device. The plasma arc generating device generates a plasma beam through the action of the cathode and the anode, and the plasma beam is sprayed out in the high-speed state to form a plasma arc. Different filamentous metal materials enter a heatsource generated by the plasma arc through the clamping device, and the fused deposition of dissimilar metal is achieved. The fused deposition of dissimilar materials has the advantages of conveniently supporting the materials and conveniently forming the materials, alloying of the materials is achieved advantageously, the strength and the hardness of the surfaces of the materials are improved, and the purpose of improving the poor performance of a single material is achieved.

Description
