Embodiment Construction

[0038] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] as attached figure 1 As shown, the present invention based on Autodesk inventor software three-dimensional modeling expands and generates the operating method of lofting coordinates, comprises the steps:

[0040] S01: Create a 2D sketch; open the Autodesk inventor software, create the first file SheetMetal.ipt and enter the sheet metal mode, import the part design drawing and generate a 2D sketch of the part, save the 2D sketch as a basic sketch after completing the 2D sketch, and close the first file documents; the design drawings of the parts are attached figure 2 As shown, it is a single section of crescent-ribbed steel bifurcation pipe with three sides chamfered.

[0041] S02: establish a three-dimensional surface; such as image 3 As shown, create a second file Sheet Metal.ipt, enter the two-dimensional sketch state...

Abstract

The invention relates to an operation method of three-dimensional modeling expansion and lofting coordinate generation based on Autodesk inventor software. The method at least comprises the following steps that S01, a two-dimensional rough draft is built; S02, a three-dimensional curved surface is built; S03, trimming is performed; S04, thickening is performed; S05, expansion is performed; S06, lofting coordinates are extracted. The method has the advantages that the expanded view repeated drawing and lofting procedures are reduced after the operation method is adopted, automation of the discharging process of a numerically controlled cutting machine is achieved, the manufacturing precision is high, product performance is stable, the cost is reduced, economic benefits are improved, and the labor cost is reduced by 3% based on manual lofting time cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an operation method for forming steel branch pipes, volutes and elbow pipes based on Autodesk inventor software three-dimensional modeling, unfolding and generating lofting coordinates. Background technique [0002] The volute, elbow pipe, and steel bifurcation pipe of the penstock system of the traditional water turbine mostly adopt the manufacturing method of steel plate rolling and welding; the common points are: many sections, cross-section changes, complex structure, and the development required for production. The graphs are numerous and cumbersome. [0003] Since the above-mentioned steel bifurcation pipes, volutes and elbow pipes are all sheet metal roll-bending parts, they are formed into metal structural parts of overall shape through blanking, rolling, assembly and welding; the process flow is as follows: [0004] First, open the sample: a...
