Intelligent CNC Roll Surfacing Welding Machine

The rolling mill is generally a cylindrical rotating body. In order to ensure the uniform overlay layer, the spiral overlay welding method is adopted. During welding, the main transmission system transmits the motion to the spindle, the spindle drives the rolling mill to rotate, and the head translates along the rolling mill axis, thereby forming an Archimedean spiral overlay weld on the working surface. Because the weld has a certain width, each weld has a certain overlap, and finally a weld overlay layer with sufficient hardness, high temperature wear resistance, and thermal fatigue resistance is formed on the working surface.

The gantry overlay welding head adopts servo drive in the longitudinal and transverse directions, and PLC programmable control can meet the requirements of curve welding and overlay welding.

Before, during and after overlay welding, flame and gas preheating, heating and insulation are adopted to provide overlay welding quality.

The active head frame is the driving system for the rotation of the workpiece. The head frame is welded by a box-type mechanism, with good rigidity, the entire drive system is built-in, and the appearance is beautiful.

The welding gantry is the carrier of the welding system, which is welded by profiles. The steel plate for installing the guide rail is welded on the crossbeam. The installation reference surface of the guide rail is processed by planing and milling with high precision.
