The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.
Referring to fig. 1-5, the embodiment of the utility model provides a high strength commercial car longeron reinforcing plate, including being used for installing vertical reinforcing plate 1 in longeron 3 side, horizontal reinforcing plate 2 is connected to the upper end of vertical reinforcing plate 1, and is specific, vertical reinforcing plate 1 and horizontal reinforcing plate 2 are by DL590 steel sheet integrated into one piece.
The vertical reinforcing plate 1 comprises a first plate body 11 positioned in the middle and second plate bodies 12 positioned on two sides; specifically, an arc-shaped transition portion is formed between the first plate body 11 and the second plate body 12. The width of the first plate body 11 is greater than that of the second plate body 12, and at least one first positioning process hole 13 is formed in the first plate body 11; a plurality of plug welding holes 14 are formed in the first plate body 11 and the second plate body 12, and each plug welding hole 14 avoids a reserved hole 34 of the longitudinal beam 3; specifically, each plug welding hole 14 is arranged in a wave shape. In this embodiment, the first positioning process hole 13 has a diameter of
The diameter of the plug welding hole 14 is
The longitudinal beam 3 is provided with a plurality of second positioning process holes 33 which correspond to the first positioning process holes 13 one by one. Specifically, an upper flanging 31 is arranged on the upper side of the longitudinal beam 3, and a lower flanging 32 is arranged on the lower side of the longitudinal beam 3; the horizontal reinforcing plate 2 abuts against the upper flange 31.
The middle part of the outer side edge of the horizontal reinforcing plate 2 is a straight line section 21, and two sides of the outer side edge of the horizontal reinforcing plate 2 are inclined sections 22.
Because the original process adopts the steps of firstly processing the hole position of the reinforcing plate and then carrying out matched riveting with the longitudinal beam, the processing precision and the material deformation cannot be effectively controlled to cause difficult assembly, and the reinforcing plate passes through the added plug welding hole
After the positioning hole is positioned, the plug welding hole is welded with the longitudinal beam into a whole, and then the longitudinal beam and the reinforcing plate are matched with the drill process for improving the process, so that the problems that the hole positions of the longitudinal beam and the reinforcing plate are not coincident and the longitudinal beam cannot be riveted are solvedAnd (5) problems are solved.
The smaller R during bending and forming of the plate is, the higher the requirement on the elongation of the material is, and when R is smaller than the plate thickness (hereinafter denoted by t) or the forming angle is larger than 90 degrees during forming of the medium plate, bending cracks are easy to occur; meanwhile, tensile experiments show that the transverse plasticity and toughness of the steel plate are lower than those of the longitudinal steel plate, so that the bending direction is vertical to the fiber direction of the plate by increasing the bending internal angle, and the high-quality high-strength DL590 steel plate is used, so that cracks generated in the bending forming process of the material can be effectively reduced, and the fatigue life of the reinforcing plate under high load and long period is prolonged.
