AI Technical Summary
When welding ultra-thin leads and tails in strip steel production line welding machines, due to poor rigidity of ultra-thin plates, the sag amount of the protruding part is inconsistent, which affects the height of the joint and welding quality.
A strip steel production line welding machine center-proof ultra-thin strip head and tail sag device is designed, including a pre-level wheel base, a lower support wheel and a laser beam. The lower plane of the drooping strip is supported at the same height by an adjustable pallet mechanism (composed of small pallets, adjustment screws and pallet mounting frame) and is welded using a laser beam.
Through this device, it is possible to ensure that the ultra-thin head and tail joints have no height difference, avoid holes in welding, thereby improving welding quality, increasing the success rate of one welding, reducing the reweld rate, and improving welding stability.
