Description
Technical field
The present invention relates to a kind of welding supporting mechanism, relate in particular to a kind of overarm formula horn that is used for suspending welder, lever welding machine, welding machine.
Background technology
At present, be used for exchanging/the intermediate frequency suspending welder, the overarm formula horn of welding equipments such as lever welding machine, welding machine generally uses copper material to make the horn body, and the cantilevered distal end of horn need be born bigger side force.When the machine of suspension throat depth was bigger, the intensity of horn and rigidity required bigger, and for satisfying requirement of strength and rigidity, necessary enlarging section is long-pending, thereby needs to strengthen the consumption of copper material, causes the material cost of horn higher.
For solving strength problem, can use aluminium to replace copper material, yet the electric conductivity of aluminium is bad, its conductive capability has only 1/3rd of copper, in order to satisfy the consumption that the conductive capability needs strengthen the cross-sectional area of horn and then strengthen aluminium, cause the increase of material cost, increase the weight of horn simultaneously.In addition, aluminium is easy to heating at conducting process, again owing to contain metal ingredient such as aluminium ion in the cooling water, and these metal ingredients produce easily the cooling water channel of bonding obstruction aluminium horn with aluminium alloy, and common aluminium to get rusty easily also be that the water hole is stopped up easily.
For gaining in strength, also can adopt copper and stainless steel composite material to make the horn body, perhaps strengthen improving the intensity of horn at the sheathed steel bushing in the copper material outside, simultaneously owing to need the copper material and the copper material of conductive exothermal all be needed to cool off, then above-mentioned these production method copper materials all should contact with steel, the Outside Dimensions that then needs to increase the horn body for the mechanical strength that improves horn, thereby increased the consumption of copper material, yet also just can't increase the size of horn significantly in order to save copper material, so horn can not bear very large side force.
Summary of the invention
At the prior art deficiency, the technical problem to be solved in the present invention provides a kind of overarm formula horn of not only having saved the conductive copper consumption but also can having guaranteed electric conductivity and intensity.
In order to overcome the prior art deficiency, the technical solution used in the present invention is: a kind of overarm formula horn, it comprises conductive copper, outer support member, root connector, outstanding end connection, the root of outer support member is fixedlyed connected with the conductive copper insulation by the root connector, fixedlys connected with described conductive copper insulation by outstanding end connection in the outstanding end of described outer support member.
As the improvement of such scheme, described outer support member is the rigidity taper shell, and described conductive copper is located at the internal cavities place of described outer support member.
As the improvement of such scheme, described outer support member is a Stainless Steel Shell.
