1.Introduction for T beam welding machine:
This machine is mainly used for automatic welding of already formed T-shaped steel. It is equipped with an automatic tracking welding arm that can move horizontally and vertically on the gantry frame, allowing the welding nozzleon the machine head to align with the weld seam. The welding arm is equipped with an automatic electronic tracking device, and then the gantry frame moves linearly on the rail to perform automatic welding. This machine is equipped with an automatic smoke collection, recycling and processing device.
The servo motor of the machine frame drives the welding arm. The welding arm moves up, down, left and right automatically through servo drive to adapt to different specifications of welding. The smoke collection and processing system mainly consists of smoke collection filtration, dust removal, etc.
The electrical control system consists of an electrical control box and an operation box. The control box is installed on the side of the welding arm to control the movement of the gantry frame. The gantry frame and the welding machine operation box are installed on the upright column of the gantry frame. The operation is very convenient.
Welding platform (1 set)
The welding platform includes 1 T-shaped steel positioning and clamping platform, and 1 positioning and clamping platform that can simultaneously hold 2 long workpieces in the length direction, and can hold 8 workpieces in the horizontal direction. It can hold up to 8 longest workpieces at one time. The horizontal direction adopts 8 sets of hydraulic clamping mechanisms, and the longitudinal intervals adopt 8 sets of positioning clamping mechanisms. The assembled T-shaped steel is fixed on the welding platform, which is conducive to the automatic positioning of the workpiece, suppresses the deformation during welding and prevents the workpiece from tipping over. In addition, 8 sets of anti-falling and flipping mechanisms are hidden in the welding platform. After welding, they are raised to prevent the T-shaped steel from loosening the clamping device and jumping up and overturning, which is beneficial for safety.
