Embodiment Construction

[0006] A rapid forming method for alloy casting, using a CAD system to perform three-dimensional modeling of parts on a computer to establish a solid model; select a placement position and design a support; convert the format of the three-dimensional solid model and send it to the computer control system of the molding machine, Use layering software to select parameters, layer the model, and obtain the plane graphics and related data of each thin layer; the three-dimensional numerical control mechanism of the molding machine controls the laser beam to scan the photohardening resin liquid in the liquid pool according to the layering parameters; the laser is irradiated to The liquid surface immediately hardens and adheres to the solidified lower layer of resin layer; the lifting table descends to a layer thickness, and the resin liquid in the container evenly covers the cured layer; according to the track given by the plane shape data of the next layer, Control the laser beam to ...

Abstract

The invention provides a rapid forming method for use in alloy casting. Three-dimensional shaping of a part is performed on a computer via a CAD (computer aided design) system, and a physical model is established; a placement position is selected, and a support is designed; after format of the physical model is converted, the physical model is transmitted to a computer control system of a shaping machine, parameters are selected via layering software, the physical model is layered, and a plane figure of each layer and related data are obtained; a three-dimensional mechanism of the shaping machine controls a laser beam to scan photo-hardened resin liquid in a liquid bath according to layering parameters. The method has the advantages that product development takes less time, product manufacturing cost is low and is unrelated to batch and complexity, the whole parts manufacturing process is digitally controlled, the size of the parts is variable, and one-time forming of various assemblies can be achieved.

Description

technical field [0001] The invention relates to a rapid forming method of alloy casting, which belongs to the technical field of machinery. Background technique [0002] The existing casting technology, no matter ordinary sand casting or powder casting method, has high product manufacturing cost, long product development time, waste of manpower and material resources, and high scrap rate in the product manufacturing process. Contents of the invention [0003] The invention provides a rapid forming method of alloy casting, which shortens the product development time, lowers the product manufacturing cost, and can realize chip-free processing of parts. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a rapid forming method of alloy casting, which uses a CAD system to perform three-dimensional modeling of parts on a computer to establish a solid model; select a placement position and design a support; ...
