AI Technical Summary

Technical Problem

In existing wire straightening equipment, the contact area between the drive wheel and the wire is small, which makes the wire prone to secondary bending during the straightening process, resulting in poor straightening effect.

Method used

The design employs two drive belts to increase the contact area with the welding wire. The welding wire is positioned by an annular groove and transported by the friction of the drive belt. Multiple through holes are also provided to increase the contact area and heat dissipation effect. Combined with a coolant tank and nozzle, the welding wire is cooled down.

Benefits of technology

It improves the stability and uniformity of welding wire straightening, avoids secondary bending of the welding wire, enhances the straightening effect, and increases the hardness of the welding wire through cooling, ensuring the stability and uniformity of the welding wire during the conveying process.

Abstract

The utility model relates to the technical field of welding wire production, in particular to a metal welding wire straightening and cutting-off device which is more stable when welding wires are conveyed backwards, bears smaller and more uniform pressure, prevents the welding wires from being bent secondarily, and improves the straightening effect. Comprising a rack, a first straightening wheel set, a second straightening wheel set, a cutting-off assembly and a discharging box. The device further comprises a driving assembly, the driving assembly is installed between the second straightening wheel set and the cutting assembly, the driving assembly comprises two driving wheels, two driven wheels, two driving belts and two annular grooves, and the two driving wheels and the two driven wheels are installed on the rack through a support. The two ends of one driving belt are arranged on the driving wheel and the driven wheel located on the upper portion in a sleeving mode respectively, the two ends of the other driving belt are arranged on the driving wheel and the driven wheel located on the lower portion in a sleeving mode respectively, annular grooves are formed in the middles of the outer surfaces of the two driving belts respectively, and the two driving belts horizontally clamp welding wires through the two annular grooves respectively.
