Description

Technical Field

[0001] The invention relates to the technical field of copper wire drawing processing equipment, in particular to a copper wire drawing surface lubrication device. Background Art

[0002] The copper wire drawing process is to draw the copper rod into the final fine wire. First, the copper rod is drawn into the primary wire by a large drawing machine, which is generally 2-3 mm thick. Then, through multiple continuous drawing and stretching processes, the diameter becomes thinner and the length continues to increase. Finally, after five or six stretchings, a copper wire with a diameter of several microns can be obtained.

[0003] Wire drawing requires the copper wire to be forced through the die under the action of external force, the cross-sectional area is compressed, and the required cross-sectional area shape and size are obtained. The copper wire generates a lot of heat and produces friction with the wire drawing die. The heat will cause the copper wire to react with the air, causing oxidation on the copper wire surface to reduce the conductivity of the copper conductor. Friction will cause the copper powder on the copper wire surface to fall off, causing blockage. In order to reduce the friction factor between the copper wire and the wire drawing die, and take away the heat and copper powder generated on the surface of the die forming area and sizing area, emulsion is needed for cooling and lubrication.

[0004] The temperature of the emulsion needs to be controlled during use. The target temperature of the emulsion is 35±5℃. Summary of the invention

[0023] like Figure 1 As shown, a copper wire drawing surface lubrication device comprises an emulsion storage tank 1, in which an emulsion having lubricating, cooling or heat-insulating functions is stored; a lubrication pump 2, which is arranged in the emulsion storage tank 1; a lubrication pipe 3, one end of which is connected to the lubrication pump 2; a lubrication head 4, which is arranged at one end of the lubrication pipe 3 away from the lubrication pump 2, and sprays the emulsion toward the drawing surface of the copper wire; and further comprises

[0024] The temperature regulating pool 5 includes a pool body 51; a cooler 52, which is arranged in the pool body 51 and is used to reduce the temperature of the emulsion in the pool body 51; a heater 53, which is arranged in the pool body 51 and is used to increase the temperature of the emulsion in the pool body 51; an inlet pipe 54, a liquid pump is provided in the middle, and the two ends are respectively connected to the pool body 51 and the emulsion storage pool 1, and is used to pump the emulsion in the emulsion storage pool 1 into the pool body 51; a liquid outlet pipe 55, a liquid pump is provided in the middle, and the two ends are respectively connected to the pool body 51 and the emulsion storage pool 1, and is used to pump the emulsion in the pool body 51 into the emulsion storage pool 1; a plurality of temperature sensors are respectively arranged in the emulsion storage pool 1 and the pool body 51, and are used to detect temperature; a controller is arranged outside the emulsion storage pool 1, and is respectively connected to the lubrication pump 2, the cooler 52, the heater 53 and the liquid pump by electrical signals.

[0032] Furthermore, in order to enhance the sedimentation effect, a supplementary partition 63 is also provided in the filter tank 6, and the supplementary partition 63 divides the left bin into a discharge bin and a static bin. The static bin is located between the discharge bin and the right bin, and the liquid inlet pipe 54 is connected to the discharge bin.
