Tungsten Carbide Tube Drawing Die

Other main products of HengRui Carbide.

Detailed Description:

• During the tube drawing process, the tube is inserted into the die, and force is applied to pull it through the die. As the tube is pulled through the die, its diameter decreases while its length increases. The die provides the necessary support and guidance to shape the tube and ensures uniform reduction in diameter.

Here is a simplified overview of the process:

1. Blank preparation: The raw material, typically a metal wire or rod, is cut into appropriate lengths to serve as blanks for forming the nuts. The blanks are usually slightly larger in diameter than the final nut size.

2. Heating: The blanks are heated to an elevated temperature to increase the material's ductility and reduce its resistance to deformation. Heating can be done using furnaces or induction heaters.

3. Transfer to the die: The heated blanks are transferred to the nuts forming die, which consists of two or more halves with cavities that match the desired nut shape. The blanks are positioned in the die cavities.

4. Forming operation: The die halves are brought together under high pressure, exerting forces on the blanks. The blanks are compressed and forced to flow into the intricate shape of the die cavity, resulting in the desired nut profile.

5. Flash formation: During the forming operation, excess material called flash is formed. Flash helps in filling the die cavities completely and prevents material leakage.

6. Flash trimming: After the forming operation, the excess flash material is trimmed off, either manually or using automated trimming processes.

7. Cooling and ejection: Once the forming and trimming are complete, the formed nuts are cooled, typically through a water quenching process. The cooled nuts are then ejected from the die.

8. Finishing operations: The formed nuts may undergo various finishing operations, such as sizing, threading, and surface treatment, to achieve the desired dimensions, thread quality, and appearance.

The nuts forming die is a critical component in this process, as it defines the shape and dimensions of the final nut. It is typically made from hardened tool steel to withstand the high pressures and temperatures involved in the nut forming process. Dies are precision-engineered to ensure consistent and accurate nut production.
