Abstract
Description
technical field
[0001] The invention relates to a profile, especially a rectangular tube profile with flanging. Background technique
[0002] At present, in the field of dump trucks, the subframe longitudinal beams are basically made of rectangular tubes. The rectangular tube is formed by welding. Although the manufacturing process of this rectangular tube is simple and the strength is good, but because the cross-sectional size is generally large, it is used on the sub-frame to cause a high center of gravity of the vehicle, and the stability of the vehicle is poor when the road is bumpy. In the middle of the vehicle, the swing is relatively large, which will have an adverse effect on prolonging the service life of the vehicle.
[0003] Our company applied for the invention patent of rectangular tube profiles in 2011, the authorized announcement number is: CN202024069U, and the authorized announcement date is November 2, 2011. The rectangular tube profiles only announced the...
Examples
Embodiment Construction
[0015] Such as figure 1 The shown rectangular pipe profile with flanging includes a pipe body 1, the pipe body 1 is in the shape of a rectangular pipe, the side 2 of the pipe body 1 extends upward, and the top of the side 2 is provided with an outward The flange 3, the angle C between the side edge 2 extending upward of the pipe body 1 and the top flange 3 is 90° or 135°, the width A of the pipe body 1 is 80 mm or 85 mm or 90 mm, and the upward extending The height B of the other side opposite to the side 2 is 140mm or 150mm or 160mm or 170mm or 180mm or 200mm, the inner angle of the pipe body 1 is an arc angle R, and the radius of the arc angle R is 8mm or 10mm or 12mm.
[0016] Such as figure 2 , image 3 As shown, the two side walls 2 in the height direction of the pipe body 1 are symmetrically welded with lifting lugs 4, and the lifting lugs 4 are provided with U-shaped bolts 5, and the pipe body 1 is installed in cooperation with the chassis girder 6 through the U-shap...
