Abstract
The utility model discloses a kind of connection structures of automobile tube beam, and including several varying cross-section ducts being connected according to design requirement, straight tube or special-shaped cast tube, wherein varying cross-section duct is used for variable cross-section section, and special-shaped cast tube is casting pipe, for special-shaped section.The utility model forms a beam coupled hardness with softness by varying cross-section duct, straight tube or special-shaped cast tube Combination Welding, the shape of varying cross-section duct, straight tube or special-shaped cast tube can accordingly be changed according to different design requirements, since varying cross-section duct and straight tube and special pipe being separated, so that processing becomes flexible, while cannot bend variable cross-section in solving the problems, such as the processing of pipe beam, the requirement of rigidity and intensity can be met again, different designs demand can be rapidly adapted to.
Description
Technical field
The utility model is related to a kind of connection structures of automobile tube beam, belong to technical field of automobile manufacture.
Background technology
Automobile tube beam is usually needed according to variable cross-section is designed and produced, due to the items such as process equipment and pipe beam material self character
The restriction of part, the trend for making variable cross-section and pipe beam deflection are all very limited, and which results in the processing of existing pipe beam
It can not achieve by the bending machining of single quarter bend, the demand in some designs can not be completed.
The content of the invention
The utility model aim is to solve the above problem of the prior art, provides one kind and exist for solving existing Guan Liang
Irrealizable bending, which becomes, in processing cuts, and pipe beam is made to meet enough rigidity and intensity, and the flexibility and changeability in manufacture, quick suitable
Answer the connection structure of the automobile tube beam of different design requirements.
In order to achieve the above objectives, used technological means is the utility model：A kind of connection structure of automobile tube beam, bag
Several varying cross-section ducts being connected according to design requirement, straight tube or special-shaped cast tube are included, wherein varying cross-section duct is used for variable cross-section section,
Special-shaped cast tube is casting pipe, for special-shaped section.
Further, the varying cross-section duct includes variable cross-section straight tube and elbow tube with varying section.
Further, the varying cross-section duct and straight tube use rectangular hollow tube.
Further, welding consent is set on the special-shaped cast tube, and varying cross-section duct, straight tube or special-shaped cast tube are according to pipe
It is welded after the mutually interspersed connection of girder construction.
The utility model advantageous effect is：One has been formed by varying cross-section duct, straight tube or special-shaped cast tube Combination Welding just
Beam that is soft and helping, the shape of varying cross-section duct, straight tube or special-shaped cast tube can accordingly be changed according to different design requirements,
Since varying cross-section duct and straight tube and special pipe being separated so that processing becomes flexible, cannot in solving the processing of pipe beam
While bending variable cross-section problem, and the requirement of rigidity and intensity can be met, different designs demand can be rapidly adapted to.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the front view of the utility model embodiment；
Fig. 2 is the top view of the utility model embodiment.
In figure：1st, the curved square tube of variable cross-section rectangle, 2, preceding special-shaped cast-steel pipe, 3, middle rectangle straight square tube, 4, rear special-shaped cast-steel pipe,
5th, rear rectangle straight square tube.
Specific embodiment
A kind of longeron as shown in Figure 1, 2, including the curved square tube 1 of sequentially connected variable cross-section rectangle, preceding special-shaped cast-steel pipe 2,
Middle rectangle straight square tube 3, rear special-shaped cast-steel pipe 4, rear rectangle straight square tube 5.Wherein, the curved square tube 1 of variable cross-section rectangle is by rectangular square tube
By being machined the rectangular bend with variable cross-section being fabricated to.
By the curved square tube 1 of variable cross-section rectangle, preceding special-shaped cast-steel pipe 2, middle rectangle straight square tube 3, rear special-shaped cast-steel pipe 4, rear rectangle
Straight square tube 5 is placed on welding fixture platform successively, and interspersed between each other after size adjusting is good, fixture steps up together, utilizes
The welding consent that front and rear abnormity cast-steel pipe 2,4 is set, is welded with rectangular square tube.
A kind of Guan Liang in the present embodiment is formed by rectangular square tube, elbow tube with varying section and special-shaped cast-steel pipe Combination Welding,
Being integrally formed one has rigidity and intensity, the longeron coupled hardness with softness.
Rectangular square tube and the shape of special-shaped cast-steel pipe can accordingly be changed according to different design requirements, special-shaped cast steel
Pipe has the design flexibility of bigger, easily molded, malleable shape, and quickly can go out finished product according to drawing making, can provide
Quick response meets the needs of different designs project.
The above is only specific embodiment of the present utility model, it is not limited to this, it is any to be familiar with the art
The technical scope that is disclosed in the utility model of technical staff in, change or replacement can be readily occurred in, should all be covered in this practicality
Within new protection domain.
