Embodiment Construction

[0035] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0036] see Figure 2 to Figure 10 , the present invention provides a manufacturing process of a rectangular box tube, which is suitable for light and thin ultra-small rectangular box tube structure, the plate material used in this type of components is Q235B, generally by 6mm+6mm, 16mm+20mm, 12mm The +16mm plate is welded, and the main weld is full fusion level II. Due to the thinness of the plate, welding deformation and internal quality control are more difficult. In order to successfully meet the requirements of the process, the following is a detailed description of each step in the manufacturing process combined with the attached drawings. The breakdown is as follows:

[0037] Step S10: Prepare webs, side panels, lining strips and pr...

Abstract

The invention discloses a process for manufacturing a rectangular box pipe. The process comprises the following steps of: 10, preparing a web, side plates, liners and process separating plates; 20, assembling the web and the liners in a superposed mode; 30, arranging the side plates and the process separating plates; 40, arranging a cover plate; 50, fixing the side plates, the cover plate and a bottom plate; and 60, grinding a main weld joint. By the process for manufacturing the rectangular box pipe, the side plates and the web are welded by the liners, so that welding current is reduced, the welding sequence of the side plates, the web and the process separating plates is reasonable, the whole body is divided into a plurality of parts, the complicated process is changed into the simple process, the accuracy of a single body is improved, and the accuracy of the whole rectangular box pipe is ensured. In addition, a plurality of process separating plates are arranged in the rectangular box pipe along the length direction, so that strength is enhanced, the rectangular box pipe cannot be subjected to twist deformation, and the requirement on straightness is met.

Description

technical field [0001] The invention relates to the production of steel structural components, in particular to a production process of a rectangular box pipe. Background technique [0002] Light and thin rectangular box tubes are used in a relatively small proportion in building steel structures. Such components are often used in mechanical equipment caps and are very commonly used in the mechanical equipment industry. The requirements for straightness and flatness of the frictional contact surface Higher than conventional components (at least 90% fit), and the level of welds must reach full melting level II and the welds must be ground flat, see figure 1 , in the existing rectangular box pipe with seams, the welding between the side plate and the cover plate is often made by opening a single V-shaped groove and then welding, such as figure 1 As shown in , it is to open a bevel on the side plate, so that there will be blunt edges on the side plate, and the weld grade canno...
