AI Technical Summary
Existing aluminum-clad steel drawing dies with tungsten alloy molds have short lifespans and large aperture variation rates. The split structure leads to repeated assembly, resulting in powder and water leakage. The mold's lifespan and precision do not meet the requirements.
The green and lightweight integrated aluminum-clad steel drawing die is made by matching the blind hole structure of the aluminum-clad steel pressure die assembly and the wire drawing die assembly, and sealing the connection with a sealing device. The inner surface of the wire drawing die core is coated with a nano-diamond coating, and all parts of the die are connected as one piece by threads.
It improves the service life and aperture accuracy of the mold, reduces powder and water leakage, enhances the precision and wear resistance of aluminum-clad steel wire drawing, and the overall weight of the mold is reduced by about 65 grams.
