Problems solved by technology

[0004] The object of the invention is to adopt laser stereo modeling (SLA), layered solid manufacturing (LOM), selective laser sintering (SLS), fused deposition manufacturing (FDM), selective laser melting in the manufacture of existing complex parts (SLM) technology has the problem of huge investment in equipment and the inability to directly prepare complex shapes, precise and dense metal parts. However, the existing electrodeposition technology can only deposit two-dimensional templates or fine three-dimensional templates and cannot obtain large-scale and complex metal parts. In order to solve the problem, invent a method and device for directly manufacturing metal parts using electrodeposition technology that can directly manufacture metal parts with arbitrary complex shapes and good mechanical properties such as high density, high strength and high precision.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as Figure 4 shown.

[0020] A method for directly manufacturing metal parts using stacked template electrodeposition technology, comprising the following steps:

[0021] First, use CAD modeling software to design the solid shape of the metal parts;

[0022] Then the CAD file in solid modeling (i.e. STL) format is processed by slicing software and saved as n layer-slicing numerical control files, and the single-layer path information is input into the cutting machine and then cut to obtain n layer-slicing templates;

[0023] Third, install the first layer template on the base electrode of the cathode tray of the electrodeposition forming system with the cathode tray and the anode tray for metal electrodeposition. After the deposition of the first layer template is completed, the anode The tray is moved out to the anode tray working platfo...

Description

technical field [0001] The present invention relates to a special processing technology and its equipment, especially a method and device for manufacturing metal parts by stacked template electrodeposition, specifically a method and device for directly manufacturing metal parts by using stacked template electrodeposition technology . Background technique [0002] In the field of mechanical manufacturing, some precision metal parts with complex structures cannot be produced by traditional methods such as turning, milling, planing, and grinding. At present, the methods that can be used to directly manufacture complex structural metal parts mainly focus on some rapid prototyping methods, that is, the use of layer-by-layer stacking manufacturing methods to achieve complex structures. For example: Laser Stereo Modeling (SLA), Layered Solid Manufacturing (LOM), Selective Laser Sintering (SLS), Fused Deposition Manufacturing (FDM), Selective Laser Melting (SLM), etc. SLA and LOM ...
