With the development of modern industry, the quality and performance requirements of metal wires are getting higher and higher, especially the tensile properties directly affect the service life and safety of the product. Therefore, it is particularly important to conduct efficient and accurate tensile property testing of metal wires. At present, in the production process of metal wires, wire drawing equipment is usually used to adjust the diameter and surface treat the wires to ensure that they meet specific application requirements.

[0054] The working principle of the present invention is as follows: when working, the two winding assemblies 100 are in operation to drive the metal wire to move along the conveying path 200, and pass through the tensile detection mechanism 300 and the wire drawing mechanism 400 in sequence; wherein, the swing arm body 311 is driven to swing to a preset angle by the first driving member 312, and the preset position of the metal wire is pulled tight and straightened by the swinging, thereby changing the tension of the metal wire; the second driving member 323 drives the first pressing roller 321 to rotate, thereby driving the metal wire to be conveyed along the conveying path 200, and during the conveying process, the elastic component 324 enables the second pressing roller 322 to maintain a tight state with the surface of the metal wire, and detects the tension through the force measuring element. The pressure changes during the drawing process are measured to detect the tensile properties of the metal wire. For the unqualified metal wire portion, the wire drawing mechanism 400 is operated to soften the metal wire portion by hot blowing through the heating nozzle 411, and then the diameter of the metal wire is adjusted through the beam port 421, and the beam is cooled through the beam channel 422, so as to repair the unqualified metal wire portion.
