The eye die of the present embodiment preferably includes an eye die holder 11 and a die hole 1 penetrating the eye die holder 11.
The eye die holder 11 is provided with a first accommodating cavity 2 and a second accommodating cavity 3, the first accommodating cavity 2 and the second accommodating cavity 3 are sequentially arranged from the inlet end to the outlet end of the eye die, and the die hole 1 penetrates through the first accommodating cavity 2 and the second accommodating cavity 3.
The solid lubricant is contained in the first containing cavity 2, the cooling liquid is contained in the second containing cavity 3, and the solid lubricant is adhered to the inner surface of the processed fine line when the processed fine line enters the first containing cavity 2, so that the resistance of the processed fine line passing through a die hole is reduced, the phenomenon that burrs occur on the surface of the processed fine line due to excessive friction caused by excessive friction is avoided while the resistance is reduced, and the surface quality of the processed fine line is greatly improved; because the in-process that is being processed the smart line through the nib is violently extruded and is out of shape to can produce a large amount of heats, the coolant liquid in second holding chamber 3 can also take away the heat on the smart line of being processed when giving the nib cooling, avoids because high temperature leads to being processed smart line surface oxidation.
Preferably, the cooling liquid is water.
Further, based on the above-mentioned method for producing a high-precision fine line, the method includes the steps of feeding the fine line to be processed from the inlet end of the rolling device group and pulling the fine line out from the outlet end of the eye module group, such processing steps enable the disc element to reduce friction force and increase rolling speed through two groups of roller press wheels arranged at a certain angle in the rolling device under the conditions of large initial diameter and large diameter variation ratio, a cooling system is not required, yield is increased, energy consumption is reduced, large diameter variation ratio is obtained at the same time, the diameter of the disc element is obviously reduced, however, because the rolling device adopts a mode of rolling by two rollers, and each roller is a semicircular arc, the fine line after processing is always elliptical, which results in poor roundness, therefore, the fine line to be processed passes through the eye module group, and a plurality of eye modules are arranged in the eye module group, the diameter-changing ratio of the processed fine line passing through each eye die is significantly reduced, the surface quality of the processed fine line is improved by the reduction of the resistance of the eye die holes, and the fine line formed by the eye die can obtain high roundness due to the high roundness of the die holes. Therefore, the efficiency of fine line machining is greatly improved, the energy consumption is obviously reduced, the precision of the machined fine line is high, the roundness is high, and the surface quality is high.
Example two
The difference from the first embodiment is that although the rolling between the two rollers of the rolling device can significantly reduce friction and can effectively extrude the fine line to reduce the straight drop and pull the line, the two rollers are both semicircular arcs, so that the fine line after processing is often elliptical, which results in poor roundness, in order to further improve the precision and roundness of the fine line, in the present embodiment, it is preferable that the inlet end of the rolling device set is further provided with a first eye die, the first eye die makes the disc element generate smaller elongation, and the aperture of the die hole of the first eye die is preferably larger than the maximum rolling distance of the rolling device in the rolling device set.
