[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a polycrystalline wire drawing die, comprising a wire drawing die sleeve 1, a first buffer ring 4 and a second buffer ring 8. A wire drawing inlet 2 is provided at the left end of the wire drawing die sleeve 1, a plurality of first springs 3 are installed at equal angles on the inner side of the wire drawing inlet 2, the first buffer ring 4 is longitudinally fixed between the plurality of first springs 3, a plurality of first balls 5 are installed on the inner side of the first buffer ring 4, a wire drawing outlet 6 is provided at the right end of the wire drawing die sleeve 1, a plurality of second springs 7 are installed at equal angles on the inner side of the wire drawing outlet 6, the second buffer ring 8 is longitudinally fixed between the plurality of second springs 7, a plurality of second balls 9 are installed on the inner side of the second buffer ring 8, a core mounting groove 10 is provided through the wire drawing outlet 6 and the wire drawing inlet 2, a polycrystalline diamond core 12 is horizontally arranged in the core mounting groove 10, this design solves the problem that in the process of high-speed drawing of the original device, once the wire material shakes, the wire material is very easy to contact with the edges of the wire drawing inlet and the wire drawing outlet and cause wear.

[0019] As the first embodiment of the utility model: a sintered powder layer 13 is provided on the inner side of the polycrystalline diamond core 12. The added sintered powder layer 13 can prevent the polycrystalline diamond core 12 from directly contacting the wire and causing wear. A plurality of threaded positioning grooves 14 are provided on the outer side of the polycrystalline diamond core 12. The added plurality of threaded positioning grooves 14 facilitate the installation of a plurality of high-strength hexagon socket bolts 11. A plurality of high-strength hexagon socket bolts 11 are inserted into the wire drawing die sleeve 1 through the thread principle. The other ends of the plurality of high-strength hexagon socket bolts 11 are respectively screwed into the plurality of threaded positioning grooves 14. The added plurality of high-strength hexagon socket bolts 11 can fix the polycrystalline diamond core 12 when it is installed in the core mounting groove 10.

[0020] The multiple first balls 5 and the multiple second balls 9 are all made of the same stainless steel material. The added multiple first balls 5 and the multiple second balls 9 can come into contact with the high-speed drawn wire, so that the high-speed drawn wire will not come into contact with the side walls of the wire drawing inlet 2 and the wire drawing outlet 6 and cause wear. When the high-speed drawn wire contacts the first ball 5 and the second ball 9 at a certain place, the ball at that place can also roll in place.

It can come into contact with the wire that is drawn at high speed and shakes, so that the wire that is drawn at high speed will not shake excessively and come into contact with the side walls of the drawing inlet 2 and the drawing outlet 6 to cause wear, and when the wire that is drawn at high speed contacts the first ball 5 and the second ball 9 at a certain place, the ball at that place can also roll in place. When the wire shakes excessively, it will be transmitted to the first buffer ring 4 or the second buffer ring 8 through the first ball 5 or the second ball 9, so that the first buffer ring 4 or the second buffer ring 8 squeezes or stretches the first spring 3 and the second spring 7 at various places, thereby achieving a buffering effect.
