Description
Technical field
It the utility model is related to a kind of resistance welder horn, more particularly to a kind of conductive radiator for connecting copper strips and aluminium arm
Structure.
Background technology
At present, in resistance welder, in order to mitigate the weight of weldering arm, cost is reduced, can usually use aluminium as horn
Material, so being conductively connected in the secondary loop of resistance welder usually using soft copper band and aluminium arm.Resistance Welding is taken over
Cheng Zhong, the all-in resistance of secondary loop is excessive, then welding current can be too small, so as to not reach welding effect or welding consumption increase.
So the all-in resistance in secondary loop should be the smaller the better, i.e. connection between part and part should be that fit-state or gap are got over
It is small better.
In the course of work of resistance welder, caloric value maximum is soft copper band, so the both ends of soft copper band preferably should
Logical cooling water, and the connected mode that traditional soft copper band and aluminium arm is directly connected to represents the junction between soft copper band and aluminium arm
Can not cooling water all（Aluminium water flowing can be corroded）；That is the radiating effect of which is bad.
Transition piece is set in connected mode shown in Fig. 1 between soft copper band 11 and aluminium arm 12, i.e., by copper strips cooling block 13 and aluminium
Arm 12 is connected and fixed using lock-screw, and the contact surface of two kinds of materials of copper aluminium can have gap, and aluminium and copper material are all
It is oxidizable material, under power on condition, internal extremely easy oxidizing blackening is so as to weakening its electric conductivity, or even due to resistance
It is excessive spark phenomenon occur.
Connection in connected mode shown in Fig. 2 between copper strips cooling block 13 and aluminium arm 12 is also to be connected using lock-screw
It is fixed together, but has used copper-aluminum composite board 15 to do transition connection between it, realizes aluminium to the connection of aluminium and copper to copper, subtract
The difference of the material of few contact surface and caused by aoxidize difference.But because the contact surface between 3 parts can have a gap, and aluminium
Material and copper material are all oxidizable materials, under power on condition, internal also extremely easy oxidizing blackening so as to weaken its electric conductivity,
Even there is spark phenomenon because resistance is excessive.Typically in order to lead to cooling water, using material of the copper material as copper strips cooling block（Aluminium
Material water flowing can be corroded）.Copper strips cooling block 13 is connected and fixed with aluminium electrode arm 12 using lock-screw, can not be solved all the time
Certainly copper aluminium material material galvanization be oxidized and the problem of weaken conductive effect.
