Device for removing liquid on surface of steel wire

Abstract

The invention discloses a device for removing liquid on the surface of a steel wire. The device comprises a pipe body and a liquid removal plug, wherein the pipe body is communicated with a high-pressure air pump; the liquid removal plug comprises a cylindrical main body part; a steel wire channel is axially formed in the main body part; a first annular bulge convexly extends at one end, close to the inlet of the steel wire channel, of the outer surface of the main body part; at least one high-pressure air channel is formed in the end surface, deviating from the inlet of the steel wire channel, of the first bulge; the high-pressure air channels extend to one end of the inlet of the steel wire channel and are communicated with the steel wire channel; a second annular bulge convexly extends at one end, close to the outlet of the steel wire channel, of the outer surface of the main body part; the pipe body is coaxial with the liquid removal plug; the outer sides of the first bulge and the second bulge are sleeved with the pipe body; the inner wall of the pipe body is hermetically connected with the first bulge and the second bulge. According to the device, the liquid on the surface of the steel wire can be blocked at the inlet of the steel wire channel under the effect of high-pressure air, so that the cross contamination of solutions in different processes can be avoided.

Description

technical field [0001] The application belongs to the field of bead wire manufacturing, in particular to a wire surface liquid removal device. Background technique [0002] With the development of lightweight and high-speed automobiles, radial tires, as an important part of automobiles, have been rapidly applied and developed due to their advantages such as high-speed, energy-saving, lightweight, and long mileage. [0003] The manufacturing process of bead wire used in tires generally includes: wire rod pretreatment process and copper plating process, and the pretreatment process includes: wire rod setting-off rust removal-water washing-electrolytic pickling-high pressure water washing- Hot water washing (preheating)-surface boronization-drying-drawing-steel wire straightening-wire take-up; copper plating process includes: steel wire unwinding-straightening-lead bath tempering-water washing-electrolytic pickling-high pressure water washing- Copper plating - high pressure wa...

AI Technical Summary

Problems solved by technology

[0004] In the wire rod pretreatment process, the steel wire needs to be rinsed with high-pressure water after electrolytic pickling to remove the acidic solution on the surface of the steel wire and avoid mutual contamination of the solutions during the hot water washing process. However, the cost of high-pressure water washing is high and requires lots of water

[0005] In the copper plating process, high-pressure water washing is also required after electrolytic pickling to remove the acidic solution on the surface of the steel wire. In addition, direct hot water washing after neutralization by alkali washing is also prone to solution pollution
