Description
Technical field
This patent is related to electric resistance welding, specifically, being a kind of electric resistance welding structure.
Background technique
Electric resistance welding has the characteristics that operating speed is fast, at low cost, high reliablity, and commonly used.But due to welding
The temperature of point is high, the surface for causing operation soldering tip (electrode) contact with welded part can rapid ablation aoxidize, cause electrode and
The contact resistance of workpiece increases and heat diffusion capabilities reduce, and welded part and soldering tip contact position is caused to generate high temperature, solder joint
Outer surface is coarse, and soldering tip and workpiece are easy adhesion, and quality of welding spot decline damages soldering tip, thus, it has to often clear up soldering tip
With the contact surface of workpiece, to avoid problems of welded quality caused by soldering tip ablation, this is not only unfavorable for quality assurance, but improve at
Originally, production efficiency is reduced.
Summary of the invention
The purpose of this patent is to provide a kind of electric resistance welding structure, it is with so that soldering tip and workpiece contact position have greatly
The structure of current flowing ability and heat-sinking capability at solder joint reduces the temperature of soldering tip and workpiece contact position, reaches protection weldering
The purpose of head.
Electric resistance welding structure described in this patent, the contact area passed through between two soldered workpiece for electric current
Less than the contact area between any one workpiece and soldering tip.
Above-mentioned electric resistance welding structure has between two soldered workpiece and protrudes the convex of at least one workpiece surface
It rises, is in contact between two workpiece by protrusion.
Above-mentioned electric resistance welding structure, protrusion are circle, rectangle, annular or other any geometries.
Above-mentioned electric resistance welding structure, protrusion and workpiece are integral structures, and protrusion is the protrusion on workpiece surface itself.
Above-mentioned electric resistance welding structure, protrusion are separate structures with workpiece independently of workpiece.
This patent the utility model has the advantages that from reduce tip wear and ensure welding quality principle, by configuring workpiece
Between contact area and soldering tip and workpiece between contact area difference, there is soldering tip and workpiece contact position and be greater than solder joint
The current flowing ability at place and the structure of heat-sinking capability reduce the temperature of soldering tip and workpiece contact position, reach the mesh of protection soldering tip
's.

Specific embodiment
Referring to shown in Fig. 1-8, soldered two workpiece 1,2 are contacted with soldering tip (electrode) 3,4 respectively.On 1 surface of workpiece
With the protrusion 11 protruded to 2 surface of workpiece, which can be Fig. 1, in 2 or Fig. 7, circle shown in 8, can also be with
It is Fig. 3, rectangle shown in 4, can also be Fig. 5, annular shown in 6.
In each figure, 13 area of contact area (or contact area area of soldering tip 4 and workpiece 2) of soldering tip 3 and workpiece 1 is equal
Greater than the contact area area of protrusion 11 and workpiece 2, the target between the two after welding also greater than workpiece 1 with workpiece 2 is contacted
Area 12.Protrusion 11 and workpiece 1 are integral structures, are the protrusions on the surface of workpiece 1 itself.Certainly, protrusion can also be independently of work
Part is separate structure with workpiece.
The core of this patent is that connecing for current flowing between workpiece can be made by being equipped between soldered workpiece
Contacting surface product is less than the structure of the contact area between soldering tip and workpiece.It from reduce tip wear and ensure welding quality principle
Set out, by configuring the difference of the contact range area between workpiece and the contact area between soldering tip and workpiece, make soldering tip with
Workpiece contact position has the structure of the current flowing ability and heat-sinking capability that are greater than at solder joint, reduces soldering tip and workpiece contact position
Temperature achievees the purpose that protect soldering tip.This patent is the high quality that ensure that solder joint, and improves the service life of soldering tip, and
Reduce the requirement of the heat resistance to soldering tip material, production cost is low, operational reliability is high, and due to without clear up soldering tip or
There is soldering tip very long cleaning cycle to be therefore very suitable for automated production application.
Between soldered workpiece, structure of the contact area less than soldering tip and work piece interface product, the knot are set
Structure either workpiece itself protrusion, be also possible to independent component, effect is to be less than the contact area between workpiece
Contact area between soldering tip and workpiece makes the contact resistance between workpiece be greater than the contact resistance between soldering tip and workpiece, weldering
When connecing, the heat of electric energy production can be concentrated mainly on the big place of resistance, and the position for keeping contact area small generates heat rapidly, Jin Errong
Change is joined into reliable solder joint, and the contact surface between soldering tip and workpiece generates heat small and thermally conductive then since contact area is big
It is good, thus temperature is low, has the very long operation service life.
Whether the claim of this patent is not influenced by following factor: being arranged between welded piece and help wlding material etc., weldering
Dot shape (such as: solder joint is round rectangular or special-shaped, plane or stereochemical structure type etc.), workpiece material, soldering tip material,
Workpiece shapes, soldering tip shape etc..The claim of this patent is not influenced by the concrete shape of the structure between the workpiece, should
Structure can be any shape, such as: it is round, rectangular, annular, special-shaped etc..The claim of this patent is not by the workpiece
Between structure and workpiece relative position influence.
