Description
Technical field
The invention belongs to the production processing technology field of copper strip and aluminum strip, especially relate to the welding procedure of a kind of novel copper strips and aluminium strip.
Background technology
On the production line that sheet metal strip is produced, made and handles, generally all need coupling together with certain intensity end to end with adjacent two sections metal to be treated bands, on production line, carry out the quantity-produced purpose to reach, all adopt welding method to connect usually mostly.But, copper, the aluminum strip of and thinner thickness lower for fusing point, traditional welding method can not satisfy its manufacturing technique requirent, in the actual process, can only take sewing process to connect, perhaps simply abandon connecting, thereby greatly reduce the production efficiency of this type of copper, aluminum strip.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency of the prior art, the welding procedure of a kind of novel copper strips and aluminium strip is provided, its technological design novelty, rationally and use easy and simple to handle, welding effect good, production efficiency is high, can effectively solve the continuous production problem of existing production line in existing copper, the aluminum strip production technology.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the welding procedure of a kind of novel copper strips and aluminium strip is characterized in that this technology may further comprise the steps:
The thickness of auxilliary material described in the thickness of base material and the step 2 all is not more than 5mm described in the above-mentioned steps one.
The thickness of described base material and auxilliary material is 0.01-5mm.
The present invention compared with prior art has the following advantages:
1, novel in design, rationally and use easy and simple to handle, only need copper that two need are connected, after the head and the tail junction of aluminum strip overlaps and places, the auxilliary material that is higher than the base material fusing point with two fusing points is clipped in the middle the coupling part that two plate substrates overlap mutually again, just adopt afterwards existing electric resistance welding equipment routinely the electric resistance welding production technology from both sides up and down the four laminate materials (comprising two plate substrates and two auxilliary materials) that are stacked together are welded simultaneously, until when two plate substrates molten solder together and two auxilliary materials stop welding when also not melting, just finish being welded to connect of two copper strips or two aluminum strip.
2, because the conductive force of auxilliary material makes that the Temperature Distribution when electric resistance welding equipment heats base material is more even, also enlarged the melting area of base material simultaneously, thereby improved bonding strength and process controllability between two plate substrates greatly.
3, low cost of manufacture, use existing electric resistance welding equipment can finish the welding of two copper, aluminum strip, further expanded the range of application of electric resistance welding, can utilize existing welding equipment reliably to connect such as sheet metal strips such as copper, aluminium, reach the quantity-produced purpose, thereby efficiently solve the tinuous production connectivity problem of copper, aluminum strip.
4, flexible operation mode, the alternative material of used auxilliary material is more, and the thickness of auxilliary material does not have strict qualification yet, usually select consistent or be slightly thinner than the sheet material of base material thickness with base material thickness, in the actual mechanical process, can select suitable auxilliary material to weld and get final product according to concrete needs, concrete application scenario and condition such as alternative material category at that time.
5, through evidence, after employing the present invention welded two plate substrates, its weld strength and manufacturability can satisfy the tinuous production requirement of copper, aluminum strip fully.
6, applied widely, the present invention can effectively expand and be suitable for to the welding procedure of other associated metal band.
In sum, modern design of the present invention, rationally, uses is easy and simple to handle, production efficiency is high, low cost of manufacture and welding effect is good, connect reliably, can effectively solve the continuous production problem of existing production line in existing copper, the aluminum strip production technology.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
