B. the end with above-mentioned hollow form cylindrical shell blank is fixed on the automatic lathe entry table, described automatic lathe is provided with the mould with a conical cavity that a usefulness high-strength alloy material forms, the other end of described hollow form cylindrical shell blank is placed the conical cavity of described mould, start described automatic lathe then, make described entry table drive described hollow form cylindrical shell blank with 2500～5000 rev/mins speed high speed rotating, control the impulse stroke axial advance described hollow form cylindrical shell blank of described mould simultaneously with 3～8mm, and the working temperature of described mould is controlled at 300～800 ℃, an end of the most described hollow form cylindrical shell blank is processed into closed spherical surface body and forms required conductive pin.
After above-mentioned steps, described conductive pin can also be put into the step slotted eye of shaping bed die, with step-like shaping patrix drift described conductive pin end is pressed into the conduction sleeve.
For make conductive pin on power supply connects better the location or with being electrically connected of adjacent homopolarity conductive pin, all right: a. puts into the location notch of groove bed die with described conductive pin, with groove patrix drift the part side of the oral area both sides of described conduction sleeve is outwards stamped out brace respectively;
The conductive pin that b. will have described brace places the punching bed die, with punching patrix drift described brace is pressed into horizontally, and stamps out installing hole on described each brace.
For the conduction sleeve that makes conductive pin has better elasticity, the conductive pin that has described installing hole can also be put into the pattern stopper slot, use, low punch is simultaneously to the motion of the conduction sleeve top of described conductive pin and make it be the reducing shape.
Compared with prior art, the invention has the advantages that the cylindrical shell that conductive pin is manufactured hollow form, compare, saved material greatly, reduced cost with existing solid bar-shaped conductive pin; The conductive pin syringe needle is closed spherical surface body, and that has not only guaranteed to be electrically connected is reliable, and has guaranteed the safety of electricity consumption; In addition, only need when conductive pin is made directly place the reducing that can finish the conductive pin syringe needle on the entry table of automatic lathe automatically to make it be closed spherical surface body the stock that cuts, procedure is simple and convenient, greatly reduces workload.
