Abstract

The invention relates to the field of steel structure building, in particular to a steel truss manufacture process which includes the following steps: shearing a steel pipe according to preset length to obtain a plurality of main pipes and a plurality of branch pipes; manufacturing a three-dimensional model through a preset steel truss structure; manufacturing CAD three-dimensional graphs through intersection lines of all the main pipe and all the branch pipes in the three-dimensional model; generating a numerical control file through each CAD three-dimensional graph; inputting each numerical control file into a numerical control relevant line cutting machine, conducting insertion line cutting on the corresponding main pipes and the corresponding branch pipes and labeling the main pipes and the branch pipes; welding the main pipes and the branch pipes according to labeled numbers to obtain the steel truss of the preset structure. By means of the steel truss manufacture process, connection accuracy and welding quality are improved, welding deformation is reduced, welding seams are continuous and smooth, labor intensity is reduced, manufacturing efficiency is improved, and the accuracy of the steel truss is further ensured.

Description

technical field

[0001] The invention relates to the field of steel structure buildings, in particular to a steel truss manufacturing process. Background technique

[0002] With the economic construction and social development, steel truss forms are widely used in comprehensive civil buildings such as large hotels and gymnasiums. As a new construction project, the production of steel truss is different from the production of industrial plant components. The most important process of this structure is the intersecting line blanking, production and welding process. The processing of pipe and section steel assembly under the traditional process conditions requires complex manual steps such as lofting, scribing, cutting, repairing and grinding after cutting, which is not only labor-intensive and inefficient, but also difficult to guarantee accuracy.

Embodiment Construction

[0035] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, the present embodiment provides a steel truss manufacturing process, including the following steps:

[0037] Step 101: cutting the steel pipe according to the preset length to obtain several main pipes and several branch pipes;

[0038] Step 102: Making the preset steel truss structure into a three-dimensional model;

[0039] Step 103: making the intersection line of each main pipe and each branch pipe in the three-dimensional model to obtain a CAD three-dimensional figure;

[0040] Step 104: generating a numerical control file for each CAD three-dimensional figure;

[0041] Step 105: Input each NC file into the NC-related wire cutting machine, and perform intersecting wire cutting on the corresponding main pipe and branch pipe, and label them;

[0042] Step 106: Weld the main ...
