Description
Technical field
Utility model device is a kind of welder for electric resistance welding, especially a kind of rolling for high-frequency resistance welding (HFRW)
Dynamic formula welding electrode.
Background technique
Electric resistance welding is passed through high-frequency current by means of two contact heads (electrode), is utilized high-frequency current using conduction feed
Kelvin effect and neighbour's effect make electric current be highly concentrated in pipe edge to be welded, and rapidly by heating of pipe blank to welding temperature, so
Pressure welding is carried out under the action of compression roller afterwards.Electric resistance welding has the advantages of thermal efficiency is high, and low energy consumption, but traditional welding electricity
Pole and welded tube friction are larger, under the conditions of high temperature and long term wear, easily leave scratch on pipe surface, influence the matter of welded tube
Amount reduces electrode life.It is of great significance so studying the novel Resistance Welding receiving electrode of one kind.
Summary of the invention
Against the above deficiency, utility model device provides a kind of roller welding electrode for high-frequency resistance welding (HFRW).
Utility model device the technical solution adopted is that: mainly include electrode rolling element, anode connection terminal, cathode connection
End, gusset piece, transmission shaft.Electrode rolling element is the revolving body with certain radian, and both ends diameter is greater than mid diameter, shape
Similar to compression roller, electrode rolling element center has through-hole, is fixedly mounted on gusset piece by transmission shaft, roller welding electricity
It is uniformly placed with three volumes on the gusset piece of pole to be gradually reduced, the similar electrode rolling element of shape and structure, two gusset pieces point
Not Lian Jie anode connection terminal and cathode connecting pin, electrode rolling element is symmetrical along V-arrangement angle two sides, close to angular aperture apex
Electrode rolling element is bigger, and is gradually reduced with electrode rolling element volume is increased with opening angular vertex spacing.Further, electrode
The curvature of rolling element is consistent with pipe curvature.
The advantages of technical solution provided by utility model device is brought and good effect:
1, the device uses roller welding electrode, and friction is small for roller welding electrode and welded tube, substantially reduces
The damage of surface of welded pipe and electrode, improves the quality of welded tube and the service life of electrode.
2, the use of the electrode rolling element of size variation makes heating focus more on the apex at V-arrangement angle, makes the heating of welded tube
It is more efficient, improve welding efficiency.
3, electrode rolling element is the revolving body with certain radian, the curvature one of curvature and welded tube corresponding position on curved surface
It causes, increases the contact area of welded tube and electrode, improve heating efficiency.
