Description
Technical field
The utility model is specifically related to electrical contact material former field, and in particular to one kind is two-sided to cut ring triplex electricity
Contact Zhi Chengmo.
Background technology
Rivet type three-layer composite electric contact is the current product for replacing double contact integral rivet type electrical contacts, electrical contact work
Using the precious metal material based on silver alloy, center section is replaced using the cheap metal based on copper for ailhead and nail pin part, can be with
Save a large amount of Precious Metals Resources.The bond strength of noble metal coating and matrix material weld layer solder side depends primarily on surface pressure
Power, solder side surface state and deformation extent, it is appropriate to increase material radial-deformation, solder side clean level can be improved, is carried
High solder side bond strength.Rivet type three-layer composite electric contact product basic size head footpath D, head thickness T, pin footpath d, the long L of pin such as Fig. 1 institutes
Show, product is generally less than the 0.05mm-0.2mm of d sizes according to pin footpath d from silk material silk material diameter, better in order to provide
Head solder side bond strength, product head footpath D and pin footpath d ratios are generally 1.8 ~ 2.2 or so, ensure head silver alloy with this
Material and copper-based material deformation extent, ensure solder side bond strength.It is less than 1.8 for head footpath D and pin footpath d ratios, in addition it is small
In 1.5, the bond strength in Product jointing face can not meet to require.The processing consideration is harsh, therefore, is badly in need of one kind and is adapted to be somebody's turn to do
The particular manufacturing craft of processing technology.
The content of the invention
In order to solve the deficiencies in the prior art, one kind two-sided ring three-layer composite electric contact of cutting of the present utility model that provides supports
Mould.
The utility model use technical solution be：One kind is two-sided to cut ring three-layer composite electric contact Zhi Chengmo, including circle
The supporting mould body of cylindricality, the centre of described cylindrical supporting mould body are provided with through hole, described cylindrical Zhi Chengmo
The clout groove of horizontal insertion is additionally provided with body, described clout slot number amount is two, is be arranged in parallel between two clout grooves, institute
The clout groove stated is vertical with through hole.
Described through hole includes step macropore and through aperture, described step macropore and is connected between aperture.
Described clout groove is connected and is mutually perpendicular to between aperture.
The side of described cylindrical supporting mould body is provided with section, and one end of described clout groove is located on section.
It is also formed between described section and the supporting mould body of cylinder for the boss with firmly installation Zhi Chengmo.
The discharge end bore of described clout groove is more than the bore of entrance point.
The discharge end of described clout groove is located on section.
The beneficial effects of the utility model are：The utility model provides a kind of two-sided ring three-layer composite electric contact of cutting and supported
Mould, include the supporting mould body of cylinder, the centre of cylindrical supporting mould body is provided with through hole, cylindrical supporting mould body
On be additionally provided with the clout groove of horizontal insertion, clout slot number amount is two, is be arranged in parallel between two clout grooves, clout groove with it is logical
Hole is vertical, based on cold welding principle, under certain pressure effect, improves material solder side radial-deformation, obtains cleaner weldering
Junction, so as to improve rivet type three-layer composite electric contact solder side bond strength.

Embodiment
The utility model is further described in conjunction with Fig. 2, Fig. 3, a kind of two-sided ring three-layer composite electric contact of cutting supports
Mould, include the supporting mould body 1 of cylinder, the centre of described cylindrical supporting mould body 1 is provided with through hole 3, and described is logical
Hole 3 includes step macropore 31 and through aperture 32, described step macropore 31 and is connected between aperture 32.Described circle
The clout groove 2 of horizontal insertion is additionally provided with the supporting mould body 1 of cylindricality, the described quantity of clout groove 2 is two, two clout grooves
It is be arranged in parallel between 2, described clout groove 2 is vertical with through hole 3.Described clout groove 2 is connected between aperture 32 and phase
It is mutually vertical.It is also formed between described section 11 and the supporting mould body 1 of cylinder for convex with firmly installation Zhi Chengmo
Platform 12.The discharge end bore of described clout groove 2 is more than the bore of entrance point.The discharge end of described clout groove 2 is located at section
On 11.The utility model is based on cold welding principle, under certain pressure effect, improves material solder side radial-deformation, obtains
Cleaner solder side, so as to improve rivet type three-layer composite electric contact solder side bond strength.
Processing technology as shown in accompanying drawing 4,5,6,
1st, noble metal, matrix material are sent into by bed die by rivet type three-layer composite electric contact automatic riveter；
