[0021] Example
[0022] Such as Figure 4 As shown, the pressure die 4 is cylindrical, and the two ends of the pressure die 4 are equipped with cemented carbide 5. The angle of the inner hole of the cemented carbide 5 at one end in the line direction is 60o, and the other end of the cemented carbide 5 The angle of the inlet direction is 6o, and the angle of the outlet 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 a firm connection between the transition joint and the wire drawing die, and the lubricating medium does not leak, the transition joint 2 is 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 die 4. In order to ensure the coaxiality of the transition joint and the pressure die and the drawing die during the...
