Description

Technical Field

[0001] This utility model relates to the field of steel wire drawing technology, specifically to a steel wire drawing device. Background Technology

[0002] Steel wire rod is the smallest type of hot-rolled steel section steel produced using drawing equipment. Its diameter typically ranges from 5 mm to 60 mm, though special specifications are sometimes available. Because steel wire rod is delivered in coils, it is also known as wire rod.

[0003] A drawing machine is an industrial piece of equipment composed of mechanical devices, lubrication systems, electrical equipment, hydraulic and pneumatic systems, etc., used to draw metal materials. Drawing machines are used to perform drawing processes on metals at room temperature. Their capacity is usually expressed as the maximum drawing force. Based on their structure, drawing machines can be classified into chain drawing machines, hydraulic drawing machines, and drum drawing machines.

[0004] Existing drawing machines often produce poor-quality steel wire during production. In addition to the drawing process itself, the quality of the raw materials is also a crucial factor. If surface impurities are not cleaned properly during the production process of existing drawing machines, they will enter the mold and cause problems such as peeling and cracking on the surface of the wire after drawing.
