Abstract
The utility model relates to an electrode cap, electrode cap body (1) and connecting rod (2) including fixed connection, electrode cap body (1) be used for the welding treat the welding, connecting rod (2) go up the cover and be equipped with a protection section of thick bamboo (3) that can reciprocate. Compared with the prior art, the utility model discloses the difficult wearing and tearing of electrode cap, cooling effect are good, and welding quality is high, the welding of specially adapted door facings board etc..
Description
Technical field
This utility model relates to welding technology field, especially relates to a kind of electrode cap.
Background technology
Currently using is generally all flat tip electrode cap for welding the electrode cap of the weldments such as door trim, electrode cap is generally all relatively larger with the contact surface of weldment, thus especially easy cause weldment welding after welding trace edge flush with part trimming, it is easily generated spatter and burr, as being also easily generated viscous electrode cap phenomenon when soldered part has dislocation fluctuation.BOCK especially for door trim welds examination requirements: from part trimming to solder joint welding trace edge≤6.0mm, will be unable to be completely covered beyond 6.0mm door trim thus causing that welding trace exposes.
In addition, the material of existing electrode cap is generally all adopt chromium-zirconium-copper class material, and its quality is softer, and electrode cap is when being externally exposed environment for a long time, very easily cause because of factors such as collisions that surface produces the abrading sections such as concave point, thus leveraging the welding quality of electrode cap.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of not easy to wear, electrode cap that welding quality is high is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electrode cap, including the fixing electrode cap body connected and connecting rod, described electrode cap body is used for welding to-be-welded pieces, and described connecting rod is arranged with protection cylinder moving up and down；
During normal state, protection cylinder moves and covers electrode cap body；
During work, protection cylinder moves down and exposes electrode cap body.
Described connecting rod and protection cylinder are threaded.
Including the weld part being isosceles trapezoid body, and the connecting portion for being connected with connecting rod.
Weld part contacts and welds the width of end face of to-be-welded pieces less than 5mm.
Described electrode cap body and connecting rod clamping are tightly connected.
Circulating water cavity is also formed inside the joint face of electrode cap body and connecting rod, be additionally provided with inside described connecting rod axially through two through holes, and connecting composition with circulating water cavity for cooling down the circulating water channel of electrode cap body, two described through holes are also respectively connected with water inlet and the outlet of outside.
Described electrode cap body is made up of chromium-zirconium-copper.
Compared with prior art, this utility model is provided with protection set moving up and down, at the idle normal state of electrode cap body, by protection putting shifting thus entangling electrode cap body, namely can well not worn and not torn by external impact by shield electrode cap body；Being additionally provided with the circulating water channel for cooling down electrode cap body inside this outer tie rod, the heat produced in welding process can be taken away by recirculated water timely, such that it is able to well the physical property of shield electrode cap material is not changed.Simultaneously, the width of the end face of electrode cap body and to-be-welded pieces contact bonding, less than 5mm, welds especially for door trim, it is possible to welding trace edge and trimming leave the gap more than 1mm, such that it is able to get rid of when welding, the weld defect that power-on and power-off polar cap electric current exists conduction and causes.
