Weldment Modeling Method Based on 3D Software

Abstract

The invention provides a weldment modeling method based on three-dimensional software, which belongs to the field of welding modeling, including the first step: drawing the finished weldment into a part in the three-dimensional software; the second step: establishing a split surface, using the split method to The whole part is divided into spliced ​​parts of different sizes, and the joints of each cut spliced ​​part are chamfered; the third step: save the part completed in the second step as an editable general-purpose file that can be opened by various 3D software Format; Step 4: Use 3D software to re-open the file generated in the third step to generate multiple features, each feature corresponds to an independent spliced ​​part in the second step, and save each feature as a separate part picture. The invention saves design time, improves work efficiency, and can ensure that the correct size of each disassembled welding part is 100%.

Description

technical field [0001] The invention belongs to the field of weldment modeling and relates to a welding modeling method based on three-dimensional software. Background technique [0002] Most of the large-diameter slurry shield machines are now in the form of normal pressure tool change. According to the process requirements, the cutter body should be designed as a box-shaped beam with a hollow structure. The connection between the spoke and the base is mostly an intersecting structure. If you follow the traditional design method, use 3D software to model each part, and then assemble it, because each part has many intersecting lines, which are not on the same plane In fact, many 3D sketches or auxiliary datum planes need to be established during the drawing process, which requires relatively high modeling ability of the designer, and many spatial curves cannot be drawn accurately, which leads to very low work efficiency and very low It is difficult to ensure the correct siz...
