Embodiment
[0022] Such as Figure 4 As shown, the pressure die 4 is cylindrical, and hard alloy 5 is installed at both ends of the pressure die 4. The angles of the inner holes of the hard alloy 5 at one end are 60o in the direction of the line respectively, and the angles of the inner holes of the hard alloy 5 at the other end are respectively 60o. The angle of the incoming wire direction is 6°, and the angle of the outgoing wire direction of the cemented carbide 5 at the other end is 80°. A transition joint 2 is installed between the cylindrical pressure die 4 and the wire drawing die 1. The transition joint 2 is olive-shaped. In order to ensure that the transition joint and the wire drawing die are firmly connected and the lubricating medium does not leak, the two ends of the transition joint 2 are The taper is set to 82o. The inner hole diameter of the transition joint 2 is 0.10-0.20mm larger than the inner hole diameter of the pressure mold 4 . In order to ensure the coaxiality of...
