Description
Technical field
The utility model relates to dumper technical field, in particulars relate to a kind of dumper and rise type back door structure.
Background technique
Self-discharging vehicle backdoor is the indispensable component of dumper, and back door plays the role of stopping material and dumps material.By
Back door is caused to open frequently, so self-discharging vehicle backdoor can be patted when being doomed discharging in the behaviour in service of dumper.
Current existing back door is tower structure, is welded on back plate panel by frame, vertical and horizontal beam etc. and is formed.By
It is welding structure in current back door, welding capacity is big, is easy to snap, and higher cost, and production is complicated, and efficiency is lower.
Therefore, how to design a kind of dumper that can solve above-mentioned technical problem rise type back door structure be the present inventor with great concentration
The project of research.
Utility model content
Rise type back door structure the purpose of the utility model is to provide a kind of dumper, structure design, production are simple, welding
Small, one-pass molding is measured, it is at low cost, light-weight, it is high-efficient.
In order to realize above scheme, the utility model provides a kind of dumper and rises type back door structure, including the rear shop front
Plate, the rear door face board are the spheric plate to central concave, and the outer rim of the rear door face board connects the frame that has a back door connection.
The utility model dumper rises type back door structure, wherein the cross section of the back door frame is ring-type.
The utility model dumper rises type back door structure, wherein the cross section of the back door frame is rectangular ring, it is described
Door face board is rectangle afterwards.
The utility model dumper rises type back door structure, wherein the back door frame is made of four back door lateral frame boards.
The utility model dumper rises type back door structure, wherein the back door panel and rear doorjamb pass through welding manner company
It connects.
The utility model dumper rises type back door structure, wherein the back door panel is made up of expanding die.
After adopting the above scheme, the utility model dumper rises by type back door structure by the way that rear door face board is used expanding die
Dome shape is made, increases the intensity of back door entirety with this, while reducing the welding capacity when production of back door, can effectively reduce
The risk and welding deformation snapped, improve the producing efficiency at back door, simultaneously because this back door structure canceled it is existing after
Crossbeam, vertical beam in door, it is possible to reduce the production of part improves whole producing efficiency, light-weight, while have compared with
Strong versatility.
Detailed description of the invention
Fig. 1 is that the utility model dumper rises the structural schematic diagram of type back door structure；
Fig. 2 is the A-A of Fig. 1 to schematic cross-sectional view；
Fig. 3 is the B-B direction schematic cross-sectional view of Fig. 1.
Specific embodiment
As shown in Figure 1 to Figure 3, the utility model dumper rise type back door structure include outer profile be rectangle rear door face board
1, rear door face board 1 is the spheric plate to central concave, after the outer rim of rear door face board 1 is connected with rectangular ring by welding manner
Doorjamb 2.Doorjamb 2 is made of four back door lateral frame boards 3 afterwards, and four back door lateral frame boards 3 are respectively welded in rear door face board 1
Four end faces.Door face board 1 is processed by expanding die afterwards.
The utility model dumper rises by type back door structure by the way that rear door face board 1 is processed into spherical surface using expanding die
Shape, increases the intensity of back door entirety with this, while reducing the welding capacity when production of back door, can effectively reduce the wind snapped
Danger and welding deformation, improve the producing efficiency at back door, simultaneously because this back door structure has been canceled in existing back door structure
Crossbeam, vertical beam, it is possible to reduce the production of part improves whole producing efficiency, light-weight, while having relatively strong general
Property.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical new to this
The range of type is defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel pair
The various changes and improvements that the technical solution of the utility model is made should all fall into claims determination of the utility model
In protection scope.
