Description
Technical field
The invention belongs to electric processing technique field, for the welding of dissimilar high-low pressure electric contacts
Processing, relates to a kind of multi-functional machined electrode system.
Background technology
The usage amount of low-voltage electrical apparatus is big, range is wide, electric contacts as core component therein,
Its electrode system design used by welding and the quality of processing directly influence the performance of formed product, intelligence
Or frame-type and large capcity breaker all to use parallel slots on busbar to be distributed one end (or two ends) parallel, and
The multichannel of connection be flexible coupling and be flexible coupling the in parallel moving contact of Multichannel Parallel that end connects constitute single supply (or
Dual power supply) electric contacts, wherein busbar be connected with soft strength moving contact component all use fixing upper and lower
Electrode machining equipment, manual, step by step, divide groove, manual portable operation is welded to connect, and all causes directly
Having influence on the unstability in the temperature rise of product, dynamic thermal stability and service life, cost is high, and efficiency is low,
Power consumption height.Prior art has the disadvantage in that
1) clamping of existing fixture is to use direct press type, and conductive copper plate (busbar, bus) is by powerful
Electric current adds thermally-induced expanding with heat and contract with cold self cannot produce release, can only make conductive copper plate (busbar, bus)
To expand with heat and contract with cold release with the variant of electrode, electrode life shortens, and after contact product welding, operation needs
Wanting shaping, car to wash process deformation, solder side is rough attractive in appearance；Clamp manual welding electric contacts size
Inconsistent, groove point slot welding connects needs and repeats repeatedly to unclamp-grip-position-clamp everywhere, and efficiency is low, welding
Yield rate is low；
2) improve constantly along with the multiplication of power industry demand, net capacity, thus cause short circuit accident to be sent out
Time raw, before short-circuit current ratio, there is the increase of at double with tens times.Super large supper-intelligent environmental protection frame-type
Breaker is badly in need of, and the contact product people of 12 grooves to 24 grooves that can carry short circuit current begin one's study,
But it is in addition to use the craft of the contact product of the intelligent frame pantograph disconnecting switch of existing 3 to 7 slot types to move point
Section Mobile welding, it is impossible to ensure the uniformity of contact, soft strength and the size of busbar three, qualification rate
The highest, more than the long weld seam accumulation machining deformation after 7 grooves, size is bad, bonding strength is bad etc. cannot
The problem solved restricts the development of jumbo electric contacts.
3) there is no guarantee that welding quality and high efficiency welding electrode system:
The shortcoming 1 conventionally descending direct press type welding electrode is: can not rationally have the carrying electric current of electrode
Effect is evenly distributed to required base, busbar groove both sides, and in each busbar groove；
The shortcoming 2 conventionally descending direct press type welding electrode is: generally use the Integral electric up and down such as tungsten, molybdenum
Pole, passes to long-time big electric current heating busbar and is flexible coupling, make the be flexible coupling termination variable color close with bus,
Harden, brittle failure, broken string bad, have a strong impact on the safety of the use of breaker and the problem of performance；
The electrode heat that welding is accumulative the most continuously, makes product the most unwelded firmly, and electrode is the most overheated soft
Change, or hot tearing make Product jointing interrupt make welding failure, electrode welding yield is few, electrode life short problem,
Production efficiency is low, and cost is high.
The shortcoming 3 conventionally descending direct press type welding electrode is: this welding to the thickness of two parts of pressure and
Height x length has restriction, exceedes restriction welding effect and significantly weakens.
The single supply of the contact group system that chip assembles at present or dual power supply processing and forming, also there is no guarantee that into
Shape stablizes high-quality and the most manual efficient equipment welding electrode system turning automation, particularly structure
Simply, easy to operate, efficiency height, welding quality stable, can be carried out continuously single supply or dual power supply contact
Group system, many specifications, multi items, multi-functional, many flute length welding line automatic welding receiving electrode system have no especially
Introduce or application.Therefore, be badly in need of at present can steady and continuous, efficiently, the dress of automatic welding overlong welded seam
Put solution problem above.
