Guide mechanism for ensuring linearity of steel wire entering die

Abstract

The invention relates to a guide mechanism for ensuring linearity of steel wire entering a die. The guide mechanism comprises a support fixedly arranged between a drawing die and a guide wheel and a guide die connected to the support, the guide die and the steel wire drawing die are concentrically arranged, and the aperture of the guide die is not less than the aperture of the front end of the drawing die. The guide die is arranged between the drawing die and the guide wheel, the external warping state of the steel wire at the front end of the drawing die is corrected through the guide die, it is ensured that the steel wire and the drawing die are basically kept coaxial when the steel wire enters the drawing die, and therefore the quality problems that the steel wire is scratched at an inlet of the drawing die for copper removal, strain and drawing transverse cracks exist, and the ovality of the steel wire exceeds the standard in the process are solved, and the product quality is improved.

Description

technical field [0001] The invention relates to a guide mechanism for ensuring the linearity of steel wire feeding into a mold. Background technique [0002] At present, the steel wire of thick-sized wet-drawn rubber hose needs to go through the positioning guide wheel to ensure linearity before the wire is fed into the mold. After the diameter of the incoming steel wire is > 2.5mm, the elasticity of the steel wire increases. After the steel wire is turned by the guide wheel, a certain degree of external disturbance arc appears ,Such as figure 1 As shown, due to the limited space of the lathe, the distance between the guide wheel and the mold is not long enough, so that the thick-gauge steel wire cannot ensure a straight line before entering the mold, resulting in the force deviation of the steel wire in the mold, uneven deformation of the steel wire during the drawing process, and deflection of the steel wire. The side of the external disturbance is severely deformed, w...

[0002] At present, the steel wire of the thick-sized wet-drawn rubber hose needs to pass through the positioning guide wheel to ensure linearity before the wire is fed into the mold. After the diameter of the incoming steel wire is > 2.5mm, the elasticity of the steel wire increases. After the steel wire is turned by the guide wheel, a certain degree of external disturbance arc appears ,like figure 1 As shown, due to the limited space of the lathe, the distance between the guide wheel and the mold is not long enough, so that the thick-gauge steel wire cannot be guaranteed to enter the mold in a straight line, resulting in the force deviation of the steel wire in the mold, uneven deformation of the steel wire during the drawing process, and deflection of the steel wire. The side of the external disturbance is severely deformed, which eventually causes quality problems such as scraping and decoppering of the steel wire at the mold entrance, severe strain, transverse cracks during drawing, and excessive ellipticity of the steel wire during the process, resulting in degradation of the finished steel wire, a decline in the pass rate, and an increase in mold consumption
