Embodiment Construction

[0027] In the present embodiment, the processing method of the H-shaped curved and twisted beam operates as follows:

[0028] 1. According to the CAD model built by the detailed drawing deepening personnel, that is, the deepening model, respectively obtain the elevation tire frame diagram 1 of the H-shaped curved torsion beam and the plane marking figure 2 ( Figure 1a , Figure 1b and Figure 1c shown);

[0029] 2. According to Figure 1a and Figure 1b The elevation tire frame shown in Figure 1 and the plane dash figure 2 On the steel platform 3, draw the upper flange contour line 4, the lower wing contour line 5 and the port line 6 of the H-shaped curved torsion beam respectively; figure 2 shown), to ensure that the height difference of each tire frame plane, that is, the height difference at both ends of the tire frame meets the size requirements in the elevation drawing, for example, figure 2 The height difference A3 of the tire frame plane of the middle gear sho...

Abstract

The invention discloses a method for processing an H-shaped crankle beam, which is characterized by comprising the following steps of: firstly, respectively obtaining a vertical face jig frame chart and a plane drawing chart of the H-shaped crankle beam according to a deepening model; drawing a top flange contour line and a bottom flange contour line of the H-shaped crankle beam on a steel platform; building each grade of jig frame on the steel platform; marking a bottom flange center line and a flame distortion correction position line on a spread bottom flange subjected to digital control cutting, baking by flame according to the flame distortion correction position; pot-welding firmly the qualified bottom flange with each grade of jig frame, installing a triangle support on the bottom flange, and processing a top flange by using the same method; rigidly fixing a web plate with the triangle support and the bottom flange by using auxiliary outside force, and pot-welding firmly; positioning and assembling the top flange on the web plate and pot-welding and fixing the top flange and the web plate; and integrally asymmetrically welding and forming on the jig frame. The invention has the advantages of simple and rapid method and high processing quality.

Description

technical field [0001] The invention relates to a processing method of a steel component, more specifically to a forming method of an H-shaped bent and twisted beam. technical background [0002] In the steel structure, there are more and more spatial bending and torsion components, and the traditional steel platform cannot meet the production and precision requirements. [0003] The H-shaped twisted beam is composed of the lower flange, the upper flange and the web. The H-shaped bent and twisted beam is a kind of irregular space bending and twisting member. ; Its production accuracy must meet all the dimensional requirements in the elevation tire frame diagram and the plane dashed line diagram; the traditional steel platform single-level tire frame surface has no height, and the projection of the upper and lower flanges coincides, so it can only be used to make regular planar components, such as H shaped beams, box columns, etc. [0004] According to the current existing ...
