Double-nozzle-scanning inclined spray type cylinder blank injection moulding device

Abstract

The invention relates to manufacturing equipment of metal materials, in particular to a double-nozzle-scanning inclined spray type cylinder blank injection moulding device. The double-nozzle-scanning inclined spray type cylinder blank injection moulding device comprises a deposition chamber, wherein a ladle used for storing molten metal and atomizing nozzles connected to the bottom of the ladle are arranged at the top of the deposition chamber, and the deposition chamber is internally provided with a rotatable deposition substrate; the deposition substrate is arranged in the center of the deposition chamber and a rotating shaft of the deposition substrate is arranged in a vertical direction, and the atomizing nozzles are arranged above the deposition substrate; and the distances between the two atomizing nozzles and the axial lead of the deposition substrate are different. The injection moulding device provided by the invention has the advantages: the operating stability and the moulding quality of the whole system are improved, and the requirement on the bonding strength of the deposition substrate and a cylinder blank is lower, thus ingot blanks in a larger scale can be conveniently manufactured; the two atomizing nozzles are adopted, and thus a large-diameter ingot blank product can be formed; waste of material and exhaust pollution can be reduced; and optimal moulding technological conditions can be conveniently formed.

Description

technical field [0001] The invention relates to metal material manufacturing equipment, in particular to a double-nozzle scanning oblique-spray cylindrical billet spray forming device. Background technique [0002] Spray forming technology is an advanced manufacturing technique for preparing rapidly setting materials, which can produce near-net shape and composite products in one process. In the production process of the known spray forming equipment, a deposition base is continuously rotated, and the atomizer and the nozzle perform reciprocating scanning motion within the radius range from the center to the edge of the billet surface, so that the metal material is continuously deposited to form a cylindrical billet. In the current research and practice results, the main axis of the atomization cone of the spraying device used is mostly in the vertical direction, while the main axis of the deposition substrate is set obliquely. For equipment with this structure, due to the ...

Problems solved by technology

For equipment with this structure, due to the continuous increase in the weight of the blank during the forming process of the cylindrical blank, the rotating shaft of the deposition base and the joint between the base and the blank are subjected to a large bending moment, which is not conducive to the smooth operation of the equipment and affects product quality. , and due to the high requirements on the bonding force between the deposition substrate and the cylindrical billet, it is difficult to meet the manufacturing requirements of large-scale, heavy-weight cylindrical billets

In addition, during the forming process of existing equipment, part of the sprayed material that is not deposited on the billet will form metal powder that is not discharged together with the exhaust gas, which not only causes waste of materials, but also has an impact on the environment
