Abstract
The utility model relates to a kind of resistance welded head, comprise top electrode clamp holder and bottom electrode clamp holder, described resistance welded head at least comprises three electrode bars, described at least two electrode bars are installed on described top electrode clamp holder, and described at least one electrode bar is installed on described bottom electrode clamp holder.The utility model has the advantage of at original electrode bar place and added again electrode bar, thereby increase welding current, meet certain Joint Strength.
Description
Technical field
The utility model relates to a kind of resistance welded head, particularly a kind of resistance welded head that comprises a plurality of electrode bars.
Background technology
In resistance welded field, resistance welded head generally includes two electrode bars at present, i.e. top electrode rod and bottom electrode rod.Yet, when welding, because electric current is larger on the impact of heat production, be below the factor of current affects welding effect: at 1) the welding initial stage, workpiece and electrode surface have the oxide of high resistivity, can make electric current suffer larger obstruction.Blocked up oxide even makes the electric current can not conducting; 2) increase along with electrode pressure in when welding, the increase amplitude of electric current is little, and the heat production causing will reduce.Joint Strength always reduces along with the increase of welding pressure; 3) for the higher welding current of the higher material requirements of fusing point.Thereby order the first two electrode bar can not meet higher welding requirements sometimes.
Utility model content
Thereby the purpose of this utility model is to provide and a kind ofly can increases the resistance welded head that welding current provides Joint Strength.
To achieve these goals, the resistance welded joint that the utility model provides, comprise top electrode clamp holder and bottom electrode clamp holder, also at least comprise three electrode bars, described at least two electrode bars are installed on described top electrode clamp holder, and described at least one electrode bar is installed on described bottom electrode clamp holder.
Preferably, described welding head comprises three electrode bars, the first top electrode rod and the second top electrode rod are installed on described top electrode clamp holder, on described bottom electrode clamp holder, are installed with bottom electrode rod, the caput of described the first top electrode rod contacts with the caput of described the second top electrode rod.
Advantageously, described the second top electrode rod is movably connected on described top electrode clamp holder.
Angle between described the first top electrode rod and described the second top electrode rod is 60 degree.
Described the first top electrode rod, described the second top electrode rod and described bottom electrode rod are made by chromium-copper.
The utility model is at original electrode bar place, to have added again the electrode bar of individual intersection, thereby increases welding current, meets certain Joint Strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment
Wherein,
1, top electrode clamp holder; 2, the first top electrode rod; 3, the second top electrode rod; 4, bottom electrode rod; 5, bottom electrode clamp holder.
The specific embodiment
With reference to Fig. 1, the resistance welded joint that the utility model provides, comprises top electrode clamp holder 1 and bottom electrode clamp holder 5, also at least comprises three electrode bars, described at least two click rods are installed on described top electrode clamp holder, and described at least one electrode bar is installed on described bottom electrode clamp holder.The quantity of electrode bar can increase as the case may be, for solder joint, have relatively high expectations, can increase electrode bar more, when having four electrode bars, top electrode clamp holder and bottom electrode clamp holder are separately installed with two electrode bars, if the total quantity of electrode bar is odd number, the electrode bar quantity on top electrode clamp holder and bottom electrode clamp holder can be distributed arbitrarily.
Preferably, as the utility model preferred embodiment, this welding head comprises three electrode bars, first top electrode rod the 2 and second top electrode rod 3 is installed on described top electrode clamp holder 1, on described bottom electrode clamp holder 5, be installed with bottom electrode rod 4, the caput of described the first top electrode rod 2 contacts with the caput of described the second top electrode rod 3.Preferably, described the second top electrode rod 3 is movably connected on described top electrode clamp holder 1.
Particularly, the relative position of first top electrode rod the 2 and second top electrode rod 3 is adjustable, thereby meet different requirements, first top electrode rod the 2 and second top electrode rod 3 relies on the threaded engagement between two electrode fixed blocks to fix, the second top electrode rod 3, by fixing with the Kong Zaiyong screw threads of horizontal direction inclination 60 degree, is 60 degree thereby make the angle between described the second top electrode rod 3 and described the first top electrode 2 rods.First top electrode rod the 2 and second top electrode rod 3 is to come adjustable by the relative position of mobile two screw threads.Thereby when welding, pass through electrode bar conductive electric current, transmission of pressure, the rapidly heat in Diffusion Welding district.
Advantageously, described the first top electrode rod 2, described the second top electrode rod 3 and described bottom electrode rod 4 are made by chromium-copper.Chromium-copper has good electric conductivity, thermal conductivity, higher hardness is wear-resisting and antiknock crack resistance.
The utility model has the advantage of the electrode bar that has added again individual intersection at original electrode bar place, thereby increase welding current, meet certain Joint Strength.
More than describe preferred specific embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design concept of the present utility model without creative work.Therefore; all technical staff in the art comply with design concept of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model and/or by the determined protection domain of claims.
