Description

Technical Field

[0001] The present application relates to the technical field of wire drawing machines, and in particular to a wire drawing drum cooling device. Background Art

[0002] More than 90% of the work consumed by carbon steel wire during cold drawing will be converted into heat. Excessive surface temperature of the steel wire will cause strain aging, increase in tensile strength, sharp decrease in toughness, and even aging embrittlement. Excessive temperature will also cause the lubricating film to rupture. For steel wires with a carbon content greater than 45%, edge martensite will be produced, making it impossible to draw.

[0003] The traditional drum cooling method is to spray water on the inner wall of the drum or spray cooling between the steel wires wound on the outside of the drum (see Chinese patent publication number CN201543663U), but both methods have inevitable disadvantages. The former: scale corrodes the inner wall of the drum, which will cause the steel wire to not be well cooled on the drum, and it is very easy to cause blockage in the cooling chamber, resulting in cooling failure; the latter: the cooling effect of the spray at the moment is not ideal, and water stains will remain on the surface of the drawn steel wire, which seriously affects the subsequent processes and leads to a decrease in the yield. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the present application provides a wire drawing drum cooling device.

[0005] The present application provides a wire drawing drum cooling device adopts the following technical solution:

[0006] A wire drawing reel cooling device comprises a reel, wherein the reel comprises an outer cylinder for winding steel wire and a heat dissipation mechanism, wherein a cylindrical partition is also installed on the inner side of the outer cylinder; the heat dissipation mechanism comprises a cooling water pipe spirally distributed between the outer cylinder and the cylindrical partition and a heat dissipation fan located at the top of the reel, wherein two cooling water pipes are provided and arranged in parallel, the inlet and outlet of the cooling water pipes both pass through the cylindrical partition, the top and bottom of the outer cylinder are rotatably connected to the cylindrical partition via bearings, and a drive disk concentric with the outer cylinder is also fixed to the outer ring of the bottom of the outer cylinder, the drive disk is driven by an external motor, and the cylindrical partition is fixed to the reel base; a heat dissipation fan, the heat dissipation fan is installed on the top of the reel, wherein a speed sensor is installed at the bottom of the heat dissipation fan, the speed sensor extends to the outside of the outer cylinder and is used to identify the speed of the outer cylinder.

[0007] By adopting the above technical scheme, the steel wire is wound through the outer cylinder in the reel, and the cooling water pipe spirally distributed between the outer cylinder and the cylindrical partition in the heat dissipation mechanism can absorb the heat on the outer cylinder and the steel wire, and discharge the heat through the external circulating water tank, and at the same time cooperate with the heat dissipation fan installed on the top of the reel to blow air to the steel wire outside the outer cylinder and the reel itself, so as to cool the reel and the steel wire.
