Multi-pass ring diameter and nose adjustment realization device

Abstract

The invention relates to the technical field of metal wire drawing, in particular to a multi-pass ring diameter and nose adjustment realization device. The device comprises a base, wherein an annularmold seat is arranged above the base; the base is fixedly connected with the mold seat through a tightness adjustment mechanism; the mold seat is internally provided with a wire drawing mold; a spherical concave surface is arranged on the inner side of the base; and a spherical bulge fitted with the spherical concave surface on the base is arranged on one side of the mold seat. With the adoption of the device, multi-pass adjustment of a steel wire is achieved on the premise that the existing structure of equipment is not changed; tests shown some wet drawing machines which produce products with unsatisfactory ring diameters and noses all the time due to poor precision can produce products with the satisfactory ring diameters and noses after the device is used; similarly, after wet drawingequipment uses the device, the ring diameters and the noses of final products are easier to adjust; the efficiency is improved; and under the same condition, a finished product rate is higher when thedevice is used.

Description

technical field [0001] The invention relates to the technical field of metal wire drawing, in particular to a device for realizing multi-pass ring diameter warping adjustment. Background technique [0002] In the metal wire drawing industry, ring diameter and warping head (vector) have always been an important product index. This index measures the residual stress of the steel wire. Most wire rod products require that the ring diameter be as large as possible and the warping head be as small as possible. . [0003] The principle of ensuring the ring diameter and head warping of the finished wire rod is mainly to keep the wire rod on a straight line as much as possible when entering the mold, drawing, and exiting the mold, so that the wire rod can ensure consistent deformation as much as possible in the circumferential and radial directions. The residual residual stress difference in the parts is basically the same, and the wire shows a better ring diameter and warped head. ...

AI Technical Summary

Problems solved by technology

However, because the diameter of the steel wire is too thin, the accuracy of the existing equipment can no longer meet the product requirements only by the linear adjustment of the last pass. It often happens that the adjustment of the ring diameter and warping head cannot meet the standard required by the customer, and the equipment cannot be used for production.

Moreover, in production practice, it is found that if the ring diameter and warp of the steel wire before the last mold are less than a certain value, the circle diameter and warp cannot be adjusted only by the correction after the last mold.
