Description

Vertical butt welding machine

Technical Field

The invention relates to a vertical butt welding machine, which is suitable for butt welding of round and special-shaped wires and bars made of materials such as steel, copper, aluminum, alloy and the like, and belongs to the technical field of welding equipment.

Background

The butt welding machine is also called as current welding machine or resistance butt welding machine, and it uses the resistance between the contact surfaces of two workpieces, and instantaneously passes through low-voltage large current to make the contact surfaces of two mutually-butted metals instantaneously heat and melt and fuse. The flash butt welding mainly utilizes the heat generated by the contact resistance of the workpiece to the mouth to heat the workpiece, the metal surface is melted, the temperature gradient is large, the heat affected zone is small, and the welding seam forms common crystal grains under the condition that the plastic denaturation is generated by the solid phase metal of the workpiece to the mouth. The weld structure and the components are close to those of basic metal (or are subjected to heat treatment), and equal-strength plastic welded joints are relatively easy to obtain. The flash process has the self-protection function of exhausting air and reducing metal oxidation. Upset forging also displaces oxides with the liquid metal out of the weld. The defects of inclusion, incomplete penetration and the like of the welding line are less, so the welding application range is wide, and metal materials which can be forged can be welded by flash butt welding in principle. Although the existing butt welding machine can clamp workpieces tightly and extrude a joint surface, the concentricity and the precision of butt welding cannot be guaranteed, the pressing force cannot be uniform, and the surface quality of a butt welding material cannot be effectively guaranteed.
