Embodiment 1
[0046] This embodiment provides a continuous extrusion molding process for a small square brass special-shaped wire rod, which is used to produce a small square brass special-shaped wire rod, which mainly includes the following steps:
[0047] 1) Preheating forming mold
[0048] Install the forming mold in a cavity, keep the forming mold flat in the cavity, put it into an electric heating box and heat it to 300°C, and then keep the constant temperature for 1h.
[0049] Among them, the specific heating process of the electric heating box is: first raise the temperature to between 100°C and 110°C, keep it for 10 minutes, then raise the temperature to 302°C, then lower the temperature to 300°C, and keep the constant temperature.
[0050] 2) Extrusion molding
[0051] Install the chamber after constant temperature treatment in the shoe seat of the extruder, check the pipeline of the extruder and turn on the extruder, take a number of heated brass rods with a length of 15cm, and a...
