Embodiment Construction

[0040] The present invention will be described in further detail below by means of specific embodiments:

[0041] The processing technology of the hyperbolic bending and torsion member includes the following steps:

[0042] (1) Cutting of bending and torsion parts: making steel plates and profiles into individual parts for processing and manufacturing double bending and torsion components. When the wing web of the twisted member is bent and twisted, the numerical control programming is used for one-to-one comparison and material cutting to ensure the geometric dimension accuracy of the unfolded wing web.

[0043] Quality control and precautions in the blanking process of twisted parts:

[0044] A. When programming, according to the model, the size of the spare parts after expansion is one-to-one in the width direction, and the length direction is based on the 0.7mm allowance of each rib plate inside the box, and the welding correction shrinkage allowance of 4 main welds not l...

Abstract

The invention belongs to the technical field of steel structural components, and in particular, discloses a double-curve bent component machining process. The double-curve bent component machining process comprises the following steps: (1) bent part blanking: steel plates and profiles are manufactured as single part plates for manufacturing double-curve bent components; (2) grooves are machined; (3) no-mold formation: wing webs are warped before box assembly through the following steps: (A) the part plates are bent by adopting a three-center circle bending machine according to drawing requirements; (B) the qualified bent part plates are warped by using a hydropress according to drawing warping requirements; and (C) self-inspection is performed on machined parts; and the inspection mode isto use foetal membranes or sample plates for warping amplitude detection; (4) sample mold frames of components are warped; and the mold frames are manufactured; (5) assembly of warped components: webs, baseplates and side plates are assembled by using the mold frames; and (6) the warped components are welded. The process can effectively solve the problems of high machining difficulty and low machining size precision of the double-curve bent components.

Description

technical field [0001] The invention belongs to the technical field of steel structural components, and in particular relates to a processing technology for a hyperbolic bending and torsion component. Background technique [0002] With the rapid development of construction engineering, many super-long-span structures and many new architectural shapes have appeared. These structures and shapes are very complicated. In order to make the structure meet the requirements of architectural shapes, some components in the structure need to change with the curvature of the structure. And changes, these changes include bending, torsion and abnormal shape of components. Due to its own weight and later bearing capacity, the concrete structure can no longer realize these shapes alone. The podium of Hengqin International Financial Center Building is a steel structure construction project. In the ground podium project of the Hengqin International Finance Center Building, the secondary membe...
