Abstract
The utility model relates to a copper-aluminum press connecting negative electrode steel bar in the electrolysing cell with aluminum generatrix in the field of electrolytic aluminum and nonferrous metal. Said device is welded from a red copper foil and an aluminum block with the method of high temperature molecular diffusion welding and fusion welding. The red copper foils are soft connected multi-layered foils, the press end and the red copper foils are integrated with the method of high temperature molecular diffusion welding; the press end is provided with 2 to 4 bolt holes. The utility model solves the problem of welding in large magnetic field and the pulling force of equipment in thermal expansion during operation, ensuring the pressrue drop between the negative electrode steel bar and the aluminum generatrix within 5MV. The device can stably work at very high temperatures as mush as 400 Celsius system , with a tensile strength of 240MPa and a shear strength of 100MPa, reducing errors from other equipment and lowering power consumption and maintenance cost.
Description
Technical field
The utility model relates to electrolytic aluminium and non-ferrous metal industry and is used for jockey between electric tank cathode rod iron and the aluminium busbar.
Background technology
Traditional connector that is used for the sector all is hard connection, adopts the mode of explosion or molten casting, and its shortcoming is need cut when maintenance, can't play and move and flexible effect, can't solve the error that causes because of installation.And maintenance and install inconveniently, when electrolytic cell currents reaches 240KA when above, powerful magnetic field can't be carried out all welding methods, can cause serious loss to production and have a power failure.The patent No. is the jockey that 200420030010.1 Chinese utility model patent discloses a kind of aluminum cell cathode steel bar and cathode aluminium busbar, it is provided with and connects soft band, connect soft band and be connected with the electric tank cathode rod iron, also be connected by the soft band of transition plate and aluminium by brace.Though this utility model patent has used the mode that is flexible coupling,, make the complex structure of device owing to be provided with brace and transition plate at the two ends that connect soft band.
Summary of the invention
The purpose of this utility model provides a kind of copper aluminium connector presser that solves the simple in structure, easy to operate of prior art problem and telescopic action is arranged.
Copper aluminium connector presser, it is characterized in that: this device is to be welded through weldering of high temperature molecular diffusion and founding by red copper foil and aluminium block, the form that is flexible coupling that red copper foil constitutes for the multiple layer of copper paillon foil, pressure connection terminal and red copper foil integrative-structure for making through the weldering of high temperature molecular diffusion; Be provided with bolt hole 2-4 at pressure connection terminal.
Described copper aluminium connector presser is characterized in that: adopt macromolecule diffusion welding (DW) to weld two copper bars in the both sides of the welding position of red copper foil and aluminium block red copper foil.
Described copper aluminium connector presser is characterized in that: the surface soldered at the pressure connection terminal of red copper foil has copper coin.
Aforesaid copper aluminium connector presser is characterized in that: adopt macromolecule diffusion welding (DW) to weld two copper bars in the both sides of the welding position of red copper foil and aluminium block red copper foil.
The advantage that compared with prior art the utlity model has is: solved the problem that can't weld greatly because of magnetic field; Solved the flexible pulling force that expands with heat and contract with cold in the equipment running process; Guaranteed that pressure drop between cathode steel bar and the aluminium busbar is in 5MV.This device working environment can stable operation in 400 ℃ hot environment, and tensile strength is 240Mpa, and shearing strength is 100Mpa, can remedy the error that miscellaneous equipment causes, and reduces the power consumption and the maintenance cost of enterprise.
