Description

Technical Field

[0002] A wire drawing machine for metals is a mechanical device used for stretching, deforming, strain hardening, etc. of metal materials. The wire drawing machine for metals is widely used in the manufacturing industry; the wire drawing machine for metals mainly passes the metal material through one or more sets of wire drawing dies to stretch and deform the blank, making it smoother and more uniform, and improving its surface quality and mechanical properties; the main uses of the wire drawing machine for metals include improving the surface quality of metal materials, enhancing the mechanical properties of metal materials, increasing the ductility of metal materials, and improving the processing accuracy and surface quality of metal materials.

[0003] The wire drawing machine for metals is mainly divided into a single-pass wire drawing machine and a continuous wire drawing machine. The single-pass wire drawing machine has only one wire drawing die box and one drawing drum, and the metal wire is drawn only once. The continuous wire drawing machine is equipped with multiple wire drawing die boxes and multiple drawing drums, and can continuously draw the metal wire in multiple passes. Since the continuous wire drawing machine has higher efficiency, it has a wider application.
