6. Tailstock: The top of the tight part adopts the air pressure tip;
7. Welding gun moving mechanism: The welding gun is pneumatically up and down, and manually moves left and right.
8. Pressure roller mechanism: Correct the straightness of the pipe through the pneumatic wheel mechanism, and also prevent the pipe from deforming during the process.
9. Lifting light curtain: The movable light curtain is arranged in front, the arc radiation and the welding splash are protected from the human body, and the equipment looks beautiful; the dust cover is provided.
10, pneumatic control system: top-level expansion, system statistics in line with national standards;
11. Electrical control system: The programmable controller (PLC) is used as the main control unit, the output point is equipped with the intermediate relay protector, and the human-machine interface touch screen is used as the parameter adjustment dialogue interface. The touch screen can set the welding speed of each layer, with the automatic gun enhancement function, manual, automatic function, output setting and current output display function.
12. The adjustment of the full digital welding specification can be realized on the console, the setting can be implemented, the welding speed can be adjusted steplessly, the numerical display, the number of welding rings are placed, and the equipment has multiple storage functions of the welding work area parameters;
13. Set the electrical control cabinet and operation box separately.
14, equipment color: paint is matt paint, the color specified by the user (users need to provide a standard color card).
V.operation procedure: (internal cylinder) manually put the workpiece on the bracket → press the pneumatic cylinder to act, tighten the workpiece → the welding gun 1 is placed in the position → the welding power supply automatically triggers the arc, reaches the normal welding current, and the workpiece rotates automatically. →When the welding is completed, the welding gun is lifted → reset → exit the top cylinder → remove
Sixth, environmental requirements:
1. Power supply (provided by the purchaser): System control: single-phase AC220V350A: three-phase 50Hz; 50Hz power AC380V
