Metal Plate Automatic Straight Linear Longitudinal Seam Flat Butt Welding Machine

【Equipment composition】

It is made up of gantry type working table, welding torch longitudinal moving mechanism, workpiece pressing mechanism, clamping tool, conductivity mechanism, welding torch lifting, clamping and adjusting mechanism, electrical control system, welding power source and pneumatic system

Main feature of plate butt welding machine

This flat butt welding machine is mainly used to finish the flat metal sheet butt joint welding automatically. Welding process is stable, continuous, automatic positioning; welding torch angle and position is adjustable; forming uniform, appearance is good, weld penetration, weld width meets the requirements, and the clamping is convenient.

1.Welding torch moving longitudinally, welding position is horizontal.

2.Metal plate thickness from 0.6-3mm adopts TIG welding mode, thickness from 3mm-6mm adopts MIG welding mode.

3.Using PLC to control the machine to work, AC variable frequency speed regulation, which ensures the equipment reliability.

4.Welding specification can be preset, storing and transferring. Through the human-machine interface can easily change the parameters and state transition.

5.Welding torch can be adjusted up and down, left and right, and by angle.

Main parameter of plate butt welding machine

1.Gantry type working table

The working table consists of fixed station, water cooling copper plate, up and down pneumatic positioning mechanism. The fixed station adopts welding lathe bed welded from square tubes and steel plates. The upper face machined and mounted with copper backing, which has a water cooling system to ensure the copper backing temperature is not to high to  affect the welding result. Pneumatic positioning air cylinders to drive the positioning plate up and down to control the seam position. When the workpieces positioned on the working table, the key pressing mechanism pressing the workpiece tightly, positioning air cylinders fall down, and start welding.  

2.Welding torch longitudinal moving mechanism

It is made up of gantry beam, linear guide rails, moving block, pinion and rack and servo motor. The gantry beam is welded from square tubes and steel plates, with the upper surface machined and mounted with guide rails and pinion and rack. The moving block is driven by servo motor via conductivity mechanism and pinion and rack to move longitudinally as well as the welding torch.

3.Welding torch clamping, adjustment and lifting mechanism

The welding torch is driven up and down by the cylinder to realize the conversion between preparation and welding stations. Welding torch adopts push wire mode to ensure wire feeding stability. Welding torch can be fine-tuned up and down, left and right, and angle. The distance between advance and retreat of welding torch can be set according to the length of workpiece.

4.Key type pressing mechanism 

The key type pneumatic pressing mechanism is driven by the cylinder around the support to evenly press the workpiece. The indenter is made of copper plate. After welding, lift, and unload.

5.Workpiece loading and unloading platform

On the platform equipped with universal rolling ball and the height is the same as the copper backing, which ensures the workpiece feeding smooth.

6.Electrical system

*Use imported PLC control, good stability, simple structure, easy maintenance

*Use Taiwan original touch screen as input and output interface, welding length, arc initiation time, welding current, voltage and welding speed can be input through the interface.

*Integrated control panel box. Control button, touch screen, welding specification control are concentrated on a panel, easy to use and operate.
