The Chinese patent of CN106298321A discloses a kind of printing method processed of three layers of composite rivet type electrical contact, and this method passes through will not
It is combined with the mutually compound realization cold welding of raw material, ailhead and nail pin pre- upset bull welding simultaneously connect, whole upsetting molding, punching and blanking.
Existing rivet type electrical contact by bond strength due to being required to restrict, and the ratio of ailhead diameter and nail pin diameter is about
Beam is 2:1；It is produced by using the silk material of line footpath smaller than nail pin diameter, so that by expanding silk during cold-heading molding
The transversely deforming amount of material guarantees the binding force between silver, copper product to increase silver-bearing copper bonded area.According to than nail pin diameter
The silk material of bigger line footpath produces, and when so that the ratio of ailhead diameter and nail pin diameter being less than 2:1, the bond strength of product is under
Drop.When ailhead diameter and excessive nail pin diameter proportion, being easy to get an electric shock in rivet after staking generates gap between reed, because
This part electric appliance producer demand nail pin diameter and the close product of ailhead diameter, to reduce the risk of riveting process.
Therefore, one kind is developed when guaranteeing bond strength between silver, copper product, is existed with reducing rivet type electrical contact
The mold of riveting process risk, is necessary.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As shown in Figure 1, a kind of rivet type electrical contact forms thick nail pin mold, including slubbing mould 1, slubbing mould needle 2, primary bottom
The side of 3, bed die needles 4 of mould and final upsetting die 5, slubbing mould 1 and final upsetting die 5 is installed with the same dynamic model frame 6, dynamic model
Frame 6 is that activity is arranged and horizontally and vertically moves back and forth.Slubbing mould needle 2 is built in slubbing mould 1
And it is slidably matched with slubbing mould 1；The side of bed die 3 is installed with the quiet mould bases 7 that can be matched with dynamic model frame 6, a bed die
Needle 4 is built in a bed die 3 and is slidably matched with a bed die 3.The side of quiet mould bases 7 is also fixedly connected with secondary bed die 8,
Secondary bed die 8 is built-in with the secondary bed die needle 9 that can be slidingly fitted with secondary bed die 8.
As shown in Figure 1, Figure 2 and Figure 3, a bed die 3 successively carried out with slubbing mould 1, final upsetting die 5 pre- upset bull welding connect, pre- upsetting at
Type operation, pre- upsetting contact after molding is moved to secondary bed die 8 by final upsetting die 5, and jumping-up forms under the cooperation of secondary bed die 8.
With rivet type electrical contact form thick nail pin mold operation and adjustment method it is as follows:
1. 1 Xiang Yici bed die of slubbing mould, 3 direction is moved, so that ag material 10 and copper product 11 are in slubbing mould 1, head
It is squeezed under the constraint of 2, bed dies 3 of road mould needle and a bed die needle 4, this is pre- upset bull welding termination process.To be managed convenient for auditor
Solution, as shown in Figure 1.
2. after slubbing mould 1 completes pre- upset bull welding termination process, being separated with 3 phase of bed die；Dynamic model frame 6 moves up, so that eventually
Upsetting mould 5 is directed at a bed die 3, and the direction of the Xiang Yici bed die 3 again of final upsetting die 5 is mobile, at 5, bed dies 3 of final upsetting die and primary bottom
Pre- upsetting forming operation is carried out under the constraint of mould needle 4.To understand convenient for auditor, as shown in Figure 2.
3. final upsetting die 5 separates after completing pre- upsetting molding with 3 phase of bed die, dynamic model frame 6 is moved down, in a bed die 3
For the pre- molding contact of upsetting by final upsetting die 5 with to lower section and secondary bed die 8 is directed at, final upsetting die 5 is mobile to secondary 8 direction of bed die,
Contact nail pin position jumping-up is formed under the constraint of final upsetting die 5, secondary bed die 8 and secondary bed die needle 9, it is dynamic to complete whole upsetting molding
Make.Specifically: jumping-up is the forging process that blank height reduces and cross section increases.Final upsetting die 5 removes secondary bottom
After mould 8, the whole molding contact of upsetting is released from secondary bed die 8 by secondary bed die needle 9, completes blanking.To understand convenient for auditor,
As shown in Figure 3.
The above process is a complete period of motion, and motion process is reciprocation cycle.Above-mentioned steps three can be with step
Step carries out together, to accelerate the production efficiency of mold.By using the mode to contact nail pin position secondary operation, contact is controlled
Ratio between head diameter and foot diameter, to provide new electric shock scheme to electric appliance producer.
