Abstract
The invention provides a welding method of an overlapped flexibly-connected sheet and a contact block, which comprises the following two steps of: firstly, selecting 8-30 clean and intact flexibly-connected sheets, making into two insert electrode tips with tungsten copper, spot welding the two ends of the flexibly-connected sheets with an inverter DC power supply spot-welding machine more than 90KVA, and forming by means of spot welding for once to form into the overlapped flexibly-connected sheet; and secondly, selecting 1 clean and intact contact block, making into two insert electrode tips with the tungsten copper, welding the contact block and the two ends of the formed overlapped flexibly-connected sheet with the inverter DC power supply spot-welding machine more than 90KVA by means of spot brazing, wherein welding material is silver copper, and the welding and fusing places are quadrate. The welding technique can reduce the contact drop among parts and reduce the heat energy at the connecting places, thereby improving the use performance of the product, prolonging the service life of the product, and promoting the high-end development of the product.
Description
Technical field
The present invention relates to a kind of welding method, relate in particular to a kind of welding method of overlapping be flexible coupling thin slice and contact block.
Technical background
At present, in the high-power contactor of sealing is produced, usually need carry out being connected of overlapping be flexible coupling thin slice and contact block, thereby reach the effect of drainage or shunting.Yet the overlapping thin slice that is flexible coupling, its two ends and contact block or with the structure of the junction of other part be very important, can directly have influence on the serviceability and the useful life of product.
In production in the past, the moulding at its thin slice two ends that are flexible coupling all is to adopt the riveted joint mode basically, and then be still the riveted joint mode that adopts being connected of contact block.Thereby cause the serviceability of product not reach requirement, or the shortening in useful life.Also this just former thereby done one's utmost to restrict the high-end development of a large amount of contactors.
Summary of the invention
Technical problem to be solved of the present invention is the contact voltage drop that reduces between the part, reduces the caloric value of junction, thereby improves the serviceability and the useful life of product, promotes the high-end development of product.
For solving the problems of the technologies described above the technical scheme that the present invention adopts be:
The welding method of overlapping be flexible coupling thin slice and contact block, this method comprises following two steps:
The first step is selected the clean complete thin slice that is flexible coupling of 8-30 piece, processes two cube electrode heads with tungsten copper earlier, carries out spot welding at the thin slice two ends that are flexible coupling with the inversion direct current power supply point welding machine more than the 90KVA then, and disposable spot welding moulding is the overlapping thin slice that is flexible coupling.
Second step; Select 1 clean complete contact block, earlier process two cube electrode heads, adopt with the inversion direct current power supply point welding machine more than the 90KVA with the overlapping thin slice two ends that are flexible coupling at contact block then and put the method for brazing welding with tungsten copper; In this step, scolder is selected HIAgCu80-5 for use.
In above-mentioned steps, the welding fusion is a rectangle.
The said thin slice that is flexible coupling is copper or copper alloy.
Said contact block is a brass.
Said scolder is a sheet.
Adopt the beneficial effect of technique scheme to be:
Reduce the contact voltage drop between the part, reduce the caloric value of junction, thereby improve the serviceability and the useful life of product, promote the high-end development of product.
