1, mold design: design a suitable mold and draw the shape of the conical structure on the mold.
2. Processing preparation: prepare the metal material to be stretched and heat it to a suitable temperature to improve its plasticity.
3. Putting into the die: put the heated metal material between the upper and lower die cavities of the die, and keep a proper pressure, leaving a certain space under the die cavity for the metal material to flow in the drawing process.
4. Drawing process: Through the extrusion and stretching of the upper and lower dies, the metal material gradually forms a conical structure in the die cavity. In the process of drawing, the extrusion force of the die gradually increases, which makes the metal material fill the die cavity more closely.
5. Cooling and curing: after drawing, the metal material in the die is cooled to room temperature and cured, thus completing the forming of the conical part.
