Abstract
The utility model relates to a metal connector, concretely an aluminum-titanium-steel lapping structure transit joint, which comprises three composite layers: an aluminum composite layer, a titanium composite layer and a steel composite layer. The utility model is characterized in that the aluminum layer is partially lapped and compounded integrally with the steel layer. The titanium layer is clamped between the aluminum layer and the steel layer. A lead angle alpha at both ends of a composite surface is more than or equal to 0 DEG and less than or equal to 90 DEG. The utility model has the advantages of reasonable structure and low weight within a unit length. The utility model can be adapted to the stress direction of materials and the joint, withstand and transfer equal load with a connector and avoid the phenomenon of stress concentration. The welding condition is easy to control. Quality of the composite surface after being welded can be guaranteed.
Description
Technical field
The utility model relates to a kind of metal connecting elements, specifically a kind of aluminium-titanium-steel bridging type structural transition joint.
Background technology
In the manufacturing processing of big machinery such as boats and ships and transporting equipment, often need constructed of aluminium part and steel construction are partly coupled together, the type of attachment of aluminum current steel construction mainly contains two kinds: riveted joint and welding.Riveted joint because of make complexity, easily loosening, perishable and compactness difference is progressively replaced by a kind of structural transition joint.The transit joint that the general now aluminum steel that adopts connects mainly is to be made up of alloy aluminum+fine aluminium (titanium)+steel successively, as depicted in figs. 1 and 2.This transit joint is simple in structure, though it has solved the problem of easily loosening, perishable and compactness difference, and many defectives below this transit joint exists at aluminium, when steel welds:
1, to welding conditional request harshness, when aluminium+aluminium (titanium)+steel welds, pad only is the thickness of aluminium or steel apart from the distance of composite surface, if there is not the welding procedure of tight temperature monitoring and science strictness that interface temperature is controlled under the critical-temperature, will bring destruction to compound interface, thereby influence boundary strength and corrosion resistance.
2, when the joint composite surface is subjected to vertical tension, crackle is opened in generation.
3, transit joint is subjected to force direction and connector inconsistent.Sheet material direction intensity is vertically＞laterally＞and thickness direction, and aluminium, the steel capital of existing transit joint are that thickness direction is stressed, particularly under Fig. 2 condition, obviously belong to and do not wait strong the connection.
The utility model content
Technical problem to be solved in the utility model is the defective that exists at the said goods, provides a kind of aluminium-titanium-steel bridging type structural transition joint, to remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises aluminium, titanium, three layers of composite bed of steel, it is characterized in that: aluminium lamination and the steel layer segment is overlapping is combined with each other, accompany one deck titanium layer in the middle of aluminium lamination and the steel layer, the lead angle α at composite surface two ends is 0 °≤α≤90 °.The length b of composite surface lap can be 10mm＜b≤150mm; The total length L of described transit joint is L＞50mm; The thickness T of steel layer and aluminium lamination

2Be 0.5mm-20mm.
The utlity model has following advantage:
1, during the welding of it and alloy aluminum and steel structure, the interface critical-temperature is controlled easily, and the joint composite surface is not easy to destroy, and temperature control, welding procedure, execution conditions is required loose relatively, and welding back composite surface quality guarantees easily.
2, it has complied with the force direction that is subjected to of material and joint, can bear and transmit and be connected the load that member equates, has reached the unification of design and construction.
3, the utility model is rational in infrastructure, has avoided the stress concentration phenomenon, and the weight of unit length is low.
