Provided with fixed groove, core rod, which coordinates, to be arranged in fixed groove, and core rod is from top successively by inlet portion, lubrication portion, compression unit, fixed
Footpath portion and export department are integrally formed, and wherein inlet portion, lubrication portion, compression unit, sizing portion and the inside edge of export department, which are formed, draws
Silk die cavity.
Further, along the wire drawing die cavity axial cross section, the folder of lubrication portion inside edge and wire drawing die cavity axial direction
Angle is 40 °, and the angle of compression unit inside edge, sizing portion inside edge with wire drawing die cavity axial direction is 15 °, export department's inner side edge
Edge and the angle of wire drawing die cavity axial direction are 70 °.
Further, die sleeve is arranged on the slide rail with fix bar.
Further, core rod inside edge is coated with coating.
Compared with prior art, the beneficial effects of the utility model are：This wire-drawing die utilizes fixed groove nesting core rod
Mode fix core rod, be conveniently replaceable core rod, prevent core rod damage from causing the mould can not to use, and bottom is provided with cunning
Rail, drive die sleeve to move by slide rail, for adjusting the diameter of wire drawing, be easy to control to adjust, while Sn- is provided with the inside of core rod
Ag-Cu material coatings, there is self-lubricating effect, effectively alleviate damage of the high heat to device caused by wire drawing, increase mould makes
Use the time limit.
