Wire drawing die box

Abstract

The invention relates to a wire drawing die box. Axial guide through holes are formed in a guide shaft and a connecting cylinder respectively, a threaded inner hole is formed in the right end of the guide shaft, external threads are arranged at one end of a cylinder body of the connecting cylinder, an outer ring table is arranged at the other end of the cylinder body of the connecting cylinder, the external thread end of the connecting cylinder is screwed into the threaded inner hole of the guide shaft, and a left inner ring table and a right inner ring table are arranged at the two ends of a mounting cylinder respectively. A mounting cylinder inner hole is in clearance fit with the outer ring table, an outer cylinder on the right side of the guide shaft is matched with the left inner ring table, a horn mouth is formed in a guide through hole opening of the connecting cylinder, a plurality of semiconductor chilling plates are arranged in the connecting cylinder at intervals in the extending direction of the guide through hole, the integrated guide shaft and the connecting cylinder are provided with water conveying pipe holes communicating with a containing cavity, and a fracture is formed in the mounting cylinder; and a regular outer circle is arranged at the large-head end of a cone and matched with the mounting cylinder inner hole, a conical hole is axially formed in the cone, a wire drawing die is embedded in the small-head end of the cone, the outer conical surface of the small-head end of the cone is matched with the horn mouth of the connecting cylinder in a sealed butt joint mode, and the mounting cylinder inner hole, the connecting cylinder and the cone form the containing cavity.

Description

technical field [0001] The invention belongs to the technical field of wire drawing devices, in particular to a wire drawing die box. Background technique [0002] Metal wire is widely used in machinery manufacturing, metal processing, petrochemical, plastic, bamboo and wood products, wire and cable and other industries. The production of metal wire is generally drawn by a wire drawing machine. During the wire drawing process, elastic deformation and The principle of plastic deformation changes the physical size and characteristics of the wire. The structure of the existing wire drawing die box is complex, and the wire drawing die is inconvenient to disassemble. The line speed is relatively high during high-efficiency production, and the temperature rise is also high, which is subject to high temperature wear. Influence, the life and reliability of the wire drawing die are low, the quality of the wire drawing is relatively poor, the key temperature control technology is not ...
