Embodiment Construction

[0015] The steel wire of the present invention directly passes through the water cooling device, and the specific implementation mode is according to figure 1 , It consists of a set die 1, a wire drawing die box 2, a wire drawing die 3, a top wire 4, a water inlet 5, a water outlet 6, a lubricating mold box 7, and a water cooling mold box 8. The drawing die box 2 is provided with a lubricating die box 7 and a water-cooling die box 8. The lubricating die box 7 is provided with a cover die 1, and the water-cooling die box 8 is provided with a drawing die 3, a top wire 4, a water inlet 5 and a water outlet 6.

[0016] The jacking wire 4 is processed with four uniformly distributed waist-shaped through-holes, and the specifications of the through-holes are: length×width×rounded corners: 20mm×10mm×R5mm.

[0017] In the steel wire direct cooling method of the present invention, cooling water is injected through the water inlet 5 to flood the top wire 4 of the steel wire, and the coo...

Abstract

The invention provides a steel wire direct water cooling device. A wire drawing die box is provided with a lubricating die box and a water-cooling die box. A sleeve die is arranged in the lubricatingdie box. The water-cooling die box is internally provided with a wire drawing die, a jackscrew, a water inlet and a water outlet. The jackscrew is provided with four kidney-shaped slotted through holes distributed uniformly. Cooling water is injected into the water-cooling die box through the water inlet to submerge the steel wire jackscrew. The cooling water flows into the kidney-shaped slotted holes of the steel wire jackscrew. It is observed that hot air is generated at an outlet of the jackscrew, water flows out of the outlet of the jackscrew, circulating water can normally flow out of thewater outlet, and the purpose of direct water cooling is achieved. The steel wire direct water cooling device is good in steel wire cooling effect, reduces work hardening, prolongs the service life of the wire drawing die and improves the product quality.

Description

technical field [0001] The invention relates to a steel wire direct water cooling method and a device thereof, belonging to the technical field of metal product processing equipment. Background technique [0002] At present, for the cooling treatment of dry drawn steel wire in China, the common cooling method is the combination of "circulating water cooling mold + spray water cooling on the inner surface of the reel". The circulating water-cooled mold can only cool the surface of the mold, and take away less than 30% of the heat generated in the mold by the wire drawing deformation work. The inner surface of the reel is sprayed with water, because the inner wall of the reel is in contact with water for a long time, it is easy to produce rust , thereby reducing the cooling effect. When drawing steel wire, only less than 10% of the work exists in the steel wire in the form of potential (work hardening and lattice distortion), more than 90% of the drawing deformation work is c...
