Embodiment 1
[0022] A cold extrusion process for high-speed rail electrical connector pins, comprising the following steps:
[0023] (1) Select the blank TP1-Y phosphorus deoxidized copper;
[0024] (2) Cut TP1-Y phosphorus deoxidized copper with an automatic band sawing machine, and the length of each cut is 70mm;
[0025] (3) Place the intercepted TP1-Y phosphorus-deoxidized copper billet in a vacuum heat treatment furnace for annealing treatment, heat it to 700°C for 2 hours, and when the temperature drops below 250°C, take out the TP1-Y phosphorus-deoxidized copper billet for 1~2 hours of air cooling to cool the TP1-Y phosphorus deoxidized copper billet to room temperature;
[0026] (4) Lubrication treatment: apply water-soluble lubricant on the surface of TP1-Y phosphorus deoxidized copper blank;
[0027] (5) Put the lubricated TP1-Y phosphorus-deoxidized copper semi-finished product in the mold bag and seal it, and use a hydraulic press to perform the first cold extrusion to obtain...

Embodiment 3
[0042] A cold extrusion process for high-speed rail electrical connector pins, comprising:
[0043] (1) Select the blank TP1-Y phosphorus deoxidized copper;
[0044] (2) Cut TP1-Y phosphorus deoxidized copper with an automatic band sawing machine, and the length of each cut is 70mm;
[0045] (3) Place the intercepted TP1-Y phosphorus-deoxidized copper billet in a vacuum heat treatment furnace for annealing treatment, heat it to 800°C for 4 hours, and when the temperature drops below 250°C, take out the TP1-Y phosphorus-deoxidized copper billet for 1~2 hours of air cooling to cool the TP1-Y phosphorus deoxidized copper billet to room temperature;
[0046] (4) Lubrication treatment: apply water-soluble lubricant on the surface of TP1-Y phosphorus deoxidized copper blank;
[0047] (5) Put the lubricated TP1-Y phosphorous deoxidized copper semi-finished product in the mold bag and seal it, and then use a hydraulic press to perform the first cold extrusion to obtain the primary p...
