Abstract
The present invention relates to a kind of electrode cap; including the electrode cap body (1) being fixedly connected and connecting rod (2); described electrode cap body (1), which is used to weld, is arranged with protection cylinder (3) moving up and down in to-be-welded pieces, described connecting rod (2).Compared with prior art, electrode cap of the present invention is easy to wear, good cooling results, and welding quality is high, is particularly suitable for use in welding of door trim etc..
Description
Technical field
The present invention relates to welding technology field, more particularly, to a kind of electrode cap.
Background technology
The electrode cap for being used to weld the weldments such as door trim used now is generally all flat tip electrode cap, electrode cap
Contact surface with weldment is generally all than larger, so as to be particularly easy to cause the welding trace edge and zero after weldment welding
Part trimming is flushed, and is also easy to produce spatter and burr, and such as soldered part has dislocation also is also easy to produce viscous electrode when fluctuating
Cap phenomenon.Examination requirements is welded especially for the BOCK of door trim：From part trimming to solder joint welding trace edge
≤ 6.0mm, will be unable to be completely covered to cause welding trace exposed beyond 6.0mm door trims.
In addition, the material of existing electrode cap is generally all to use chromium-zirconium-copper class material, its quality is softer, and
Electrode cap easily causes surface to produce concave point etc. when being externally exposed environment for a long time because of the factor such as collision
Abrading section, so as to leverage the welding quality of electrode cap.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide it is a kind of it is not easy to wear,
The high electrode cap of welding quality.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of electrode cap, including the electrode cap body and connecting rod being fixedly connected, described electrode cap body are used to weld
Receive and be arranged with protection cylinder moving up and down in weldment, described connecting rod；
During normal state, protection cylinder moves up and covers electrode cap body；
During work, protection cylinder moves down and exposes electrode cap body.
Described connecting rod and protection cylinder threaded connection.
Including the weld part in isosceles trapezoid body, and the connecting portion for being connected with connecting rod.
The width that the top surface of to-be-welded pieces is contacted and welded on weld part is no more than 5mm.
Described electrode cap body is tightly connected with connecting rod clamping.
Also formed and also set inside circulating water cavity, described connecting rod inside electrode cap body and the joint face of connecting rod
Have axially through two through holes, and connect with circulating water cavity composition and be used to cool down the recirculated water of electrode cap body and lead to
Road, two described through holes are also respectively connected with the water inlet and delivery port of outside.
Described electrode cap body is made up of chromium-zirconium-copper.
Compared with prior art, the present invention is provided with protective case moving up and down, is not worked in electrode cap body
Normal state, by the way that protective case is moved up so as to entangling electrode cap body, you can with good guard electrode cap sheet
Body is not worn and torn by external impact；The circulating water channel for cooling down electrode cap body is additionally provided with inside this outer tie rod,
The heat produced in welding process timely can be taken away by recirculated water, so as to good guard electrode cap material
Physical property be not changed.Meanwhile, the width of electrode cap body and the top surface of to-be-welded pieces contact weld is no more than
5mm, for being welded especially for door trim, can welding trace edge and trimming leave gap more than 1mm, from
And can exclude in welding, there is weld defect caused by conduction in power-on and power-off polar cap electric current.
