Description
Technical field
The invention belongs to electric technical field of processing equipment, relate to a kind of multi-functional system of processing of contact of breaker.
Background technology
The use amount of low-voltage electrical apparatus is large, the scope of application is wide, contact elements is as core component wherein, its quality of welding electrode system design used and processing directly has influence on the performance of formed product, intelligence or frame-type and large capcity breaker all adopt the one end (or two ends) that distributes of parallel slots on busbar parallel, multichannel in parallel be flexible coupling and the be flexible coupling moving contact of Multichannel Parallel parallel connection that end connects forms single supply (or duplicate supply) contact elements, wherein busbar is connected with soft strength moving contact component and all adopts fixing upper/lower electrode process equipment, manual, step by step, divide groove, manual portable operation is welded to connect, all cause the temperature rise directly having influence on product, the unsteadiness in dynamic thermal stability and useful life, cost is high, efficiency is low, consume energy high.There is following shortcoming in prior art:
1) clamping of existing fixture adopts direct press type, what conductive copper plate (busbar, bus) was subject to that powerful current flow heats causes expands with heat and contract with cold and self cannot produce release, the variant of conductive copper plate (busbar, bus) and electrode can only be made will to expand with heat and contract with cold release, electrode life shortens, after contact product welding, operation needs shaping, process distortion washed by car, and solder side is rough attractive in appearance; Clamp manual welding contact elements size is inconsistent, and a groove point slot welding connects needs and repeats repeatedly to unclamp-gripping-location-clamping everywhere, and efficiency is low, solder yield is low;

The electrode heat that simultaneously continuous welding is accumulative, makes product also non-firm welding, and electrode is through thermal softening, or hot tearing makes Product jointing interrupt making welding failure, and electrode welding output is few, electrode life short problem, production efficiency is low, and cost is high.
Conventionally descend the shortcoming 3 of direct press type welding electrode to be: this welding has restriction to the thickness of pressure two parts and height x length, exceed restriction welding effect and greatly weaken.
The single supply of the contact group system of current chip assembling or duplicate supply processing and forming, also do not ensure that form stable high-quality and craft desirable efficiently turn the equipment welding electrode system of automation, particularly structure is simple, easy to operate, efficiency is high, welding quality stable, can carry out single supply or duplicate supply contact group system continuously, and many specifications, multi items, multi-functional, multiple-grooved long welding line automatic welding receiving electrode system have no especially to be introduced or application.Therefore, being badly in need of at present can steady and continuous, and device that is efficient, automatic welding overlong welded seam overcomes the above problems.
