Abstract

The invention provides a rectangular tube profile with a flange. The rectangular tube profile comprises a tube body in a rectangular tube shape. One side edge of the tube body extends upwards. The outward flange is arranged at the top end of the side edge. The angle between the upwards extending side edge of the tube body and the flange at the top end of the side edge is 80 degrees-150 degrees. The width of the tube body is 75 mm-100 mm. The height of the other side edge opposite to the upwards extending side edge is 140 mm-200 mm. The interior angle of the tube body is a circular-arc angle of which the radius is 8 mm-12 mm. By using the rectangular tube profile with the flange, production standardization is facilitated through refinement of the specifications of the rectangular tube, the utilization rate of the tube is increased, the production cost for a company is reduced, and installing is convenient and fast.

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...
