Problems solved by technology
In the prior art copper wire drawing dies, the copper wires are easily broken when the copper wires are forced to pass through the wire drawing dies with smaller apertures during the wire drawing process.
At the same time, in the wire drawing process of the existing copper wire drawing die, multiple wire drawing dies with different apertures are required to gradually reduce the wire diameter of the copper wire, and the production process is troublesome.

Embodiment 1
[0030] Please refer to Figure 1-Figure 6 , a copper wire drawing die provided in this embodiment includes a housing 100 and several rolling wheels.
[0031] The housing 100 is tubular, and the middle part of its outer wall is provided with transmission teeth 110 along the circumference of the outer wall. The inner wall of the housing 100 is provided with three connecting rods 120 connecting the rollers along the circumference of the housing 100 . The three connecting rods 120 are evenly distributed along the circumference of the housing 100 and all extend toward the central axis of the housing 100 .
[0032] The rolling wheel includes an inlet section 210 , a compression section 220 , a sizing section 230 and an outlet section 240 . The sizing section 230 is in the shape of a column, and the entrance section 210, the compression section 220 and the exit section 240 of the rolling wheel are all in the shape of a truncated cone. The large-diameter end of the compression secti...

The invention relates to the field of copper wire drawing equipment, and discloses a copper wire drawing die. The copper wire drawing die comprises a shell and a plurality of rolling wheels; the shellis shaped like a tube, and the outer wall of the shell is provided with transmission teeth; the inner wall of the shell is provided with a plurality of connecting rods; each rolling wheel sequentially comprises an inlet section, a compressing section, a sizing section and an outlet section; and each rolling wheel is connected to the corresponding connecting rod, the inlet sections of the plurality of rolling wheels are close to the same end of the shell, and then a copper wire channel is formed among the plurality of rolling wheels in a surrounding mode. In the process that a copper wire passes through the copper wire channel, the plurality of rolling wheels rotating along with the shell are closely attached to the surface of the copper wire to roll the copper wire, the wire diameter of the copper wire is gradually decreased in the rolling process, the tensile force that the copper wire passes through the copper wire channel is greatly decreased, and the condition that the copper wireis pulled to be broken is avoided.
Description
technical field [0001] The invention relates to the field of copper wire drawing equipment, in particular to a copper wire drawing die. Background technique [0002] Drawing dies usually refer to various dies for drawing metal wires, as well as drawing dies for drawing optical fibers. The center of all wire drawing dies has a hole of a certain shape, round, square, octagonal or other special shapes. The metal shrinks in size and even changes shape as it is pulled through the die hole. In the prior art copper wire drawing dies, when the copper wires are forced to pass through the wire drawing dies with smaller apertures during the wire drawing process, the copper wires are easily broken. At the same time, in the wire drawing process of the copper wire drawing die in the prior art, a plurality of wire drawing dies with different apertures are required to gradually reduce the wire diameter of the copper wire, which makes the production process troublesome.
