Embodiment 1
[0021] The wire rod is φ12.5mm82B wire rod.
[0022] (1) Straightening: Straighten the heads of the two wire rods respectively, remove the burrs at the cutting heads with a grinding wheel, and perform 45° chamfering treatment with a length of 2mm.
[0023] (2) Grinding head: Grinding the end of the wire rod, after grinding the head, use sandpaper to clean the impurities around the end of the wire rod.
[0024] (3) Butt welding: respectively clamp the wire rod processed in step (2) to the welding position of the welding machine and use resistance butt welding for welding. The wire rod at both ends should be kept horizontal. If the clamping mechanism is found to be loose, it should be adjusted in time . The welding temperature of the steel wire is 1080-1270°C, the upsetting time is 3-8s, the width of the weld is 1-3mm, the height of the weld is 2-3mm, and there are uniform cracks around it. Cool naturally to 30-40°C at ambient temperature. After the welding is completed, grin...
