YF Metal Tech as one of the Copper Wire Drawing Machine Manufacturers now introduces the factors that affect the drawing of copper wire drawing machines:
- Copper and aluminum rod (wire) materials are used in copper wire drawing machines. When other conditions are the same, the tensile force of pulling copper wire is greater than that of aluminum wire, and aluminum wire is easy to break, so a larger safety factor should be adopted when pulling aluminum wire.
- Tensile strength of copper wire material. The tensile strength of a material depends on many factors, such as the chemical composition of the material, the rolling process, etc. The higher the tensile strength, the greater the tensile force.
- Degree of deformation. The greater the degree of deformation, the longer the deformation section in the die hole, which increases the positive pressure on the line of the die hole, the friction force also increases, and the tensile force also increases.
- The friction coefficient between the wire of the copper wire drawing machine and the die hole. The greater the friction coefficient, the greater the tensile force. The friction coefficient is determined by the finish of the wire and mold materials, and the composition and quantity of the lubricant.
- The size and shape of the wire die hole working area and sizing area of the copper wire drawing machine. The larger the sizing area, the greater the tensile force.
- The position of the wire mold of the copper wire drawing machine. Improper placement of the wire mold or skewing of the mold base will also increase the tensile force. Also the wire diameter and surface quality are not up to standard.
- External factors. If the wire is not straight, the jitter of the wire during the pulling process, and the resistance to unwinding will all increase the tensile force.
YF Metal Tech is one of the Copper Wire Drawing Machine Manufacturers. We introduce in detail the characteristics of the copper wire drawing machine:
- The stretched wire has a more precise size, a smooth surface, and various cross-sectional shapes.
- Can stretch wires of large lengths and various diameters.
- Mainly cold processing, the drawing process, molds, and equipment are simple, and the production efficiency is high.
- Tensile energy consumption is large, and deformation is subject to certain restrictions.
YF Metal Tech is one of the one-stop Copper Wire Drawing Machine Manufacturers able to design, manufacture, install, and commission your wire drawing machine plant from A to Z.
