Abstract
A kind of concave dumping car header board, by interior notch board and be connected to the first backboard of the interior notch board left and right sides, the second backboard forms, in the cavity of described interior notch board, turning is oblique angle, the interior notch board left and right sides have coupling end along limit respectively to outer bending forming; The utility model uses number of parts few, and technique is simple, and productive costs is low, is convenient to promote the use of.
Description
Technical field
The utility model relates to tipper carriage part, particularly relates to a kind of concave dumping car header board.
Background technology
Dumping car header board is a component part of railway carriage, and for the side plate of loading space, base plate are connected into an entirety, front lifting-up dump truck header board also plays installs the effect of elevating ram, and concave dumping car header board can the installation of solution oil cylinder when never affecting car load overall length.
Existing concave dumping car header board, the body type structure that in many employings one piece, notch board and two pieces of backboards and reinforced rib are welded, as depicted in figs. 1 and 2, for indent dumping car header board in prior art, be made up of interior notch board 1 and the first backboard 2, second backboard 3 of being connected to interior notch board 1 left and right sides, then on two backboards and in interior notch board 1 cavity, add vertical strengthening ribs 4 and cross reinforcing 5; This structure exists: number of parts is many, and waste of material is large, and car weight increases; Weld shape changeable amount is large, and the many impacts of outside weld seam are attractive in appearance; Complex process, the defects such as production efficiency is low, and manufacturing cost is high.
Summary of the invention
In order to overcome existing indent dumping car header board, to have number of parts many, and complex process, the technological deficiency that manufacturing cost is high, the utility model proposes a kind of concave dumping car header board.
For this reason, the technical solution of the utility model is: a kind of concave dumping car header board, by interior notch board and be connected to the first backboard of the interior notch board left and right sides, the second backboard forms, it is characterized in that: in the cavity of described interior notch board, turning is oblique angle, the interior notch board left and right sides have coupling end along limit respectively to outer bending forming.
Further limit technique scheme, the cross section of described coupling end inner chamber is rectangle.
Further limit technique scheme, described interior notch board passes through roll-in or the one-shot forming of punch forming mode by steel plate.
Further improve technique scheme, be provided with 2 ~ 4 cross reinforcings in the cavity of described interior notch board, cross reinforcing is horizontal brace panel.
Beneficial effect: the utility model, changes oblique angle into by being provided with turning in coupling end and cavity along limit in the both sides of interior notch board, this enhances intensity and add railway carriage volume, and has and decrease welding process, saves material, alleviates the advantage of car weight; The utility model uses number of parts few, and technique is simple, and productive costs is low, is convenient to promote the use of.

Number in the figure is: 1 is interior notch board, and 2 is first backboards, and 3 is second backboards, and 4 is vertical strengthening ribs, and 5 is cross reinforcings, and 6 is oblique angles, and 7 is coupling ends, and 8 is brace panels, and 9 is elevating ram seats.
Detailed description of the invention
As shown in Fig. 3, Fig. 4 and Fig. 5, a kind of concave dumping car header board, comprises interior notch board, is cavity in the middle part of interior notch board 1, and in cavity, turning is oblique angle 6, and cavity can hold elevating ram; Interior notch board 1 left and right sides have coupling end 7 along limit respectively to outer bending forming, the coupling end 7 of interior notch board 1 both sides is connected with the first backboard 2, second backboard 3 respectively by welding manner; Such structure adds the intensity of header board, adds the volume of railway carriage simultaneously.
As shown in Figure 3, described interior notch board by roll-in or the one-shot forming of punch forming mode by steel plate, is which increased the intensity of header board and the volume of railway carriage, decreases materials and processing step.
As shown in Figure 3, the cross section of described coupling end inner chamber is rectangle, which increases the intensity of header board and the volume of railway carriage, and the coupling end size of interior notch board both sides and shape can adjust arbitrarily.
As shown in Figure 6, be provided with 3 cross reinforcings in the cavity of described interior notch board, cross reinforcing is horizontal brace panel, and brace panel thickness can adjust according to vehicle demand, which increases intensity and the volume of header board, decreases materials and processing step.
In described in the utility model, the both sides coupling end of notch board can carry out the adjustment of size and shape according to the actual requirements; Oblique angle shape in described interior notch board cavity and size can adjust according to the actual requirements.
