LSA1500 mm Longitudinal Seam Welder Pneumatic Piano Clamp Tanks , Argon-arc Welding

LSW1000 Longitudinal Seam Welder  with , Argon-arc Welding

       LSW1000 Longitudinal Seam welding machine is suitable for thin wall cylindrical workpiece or flat workpiece use automatic buttb welding .

Main Structure :

      Mechanical structure: host of the cantilever structure to ensure that the workpiece loading and unloading, the use of pneumatic keys plate fixture, ensure the pressing on joints evenly throughout the weld length range, part of one side welding; between the core shaft and the keys platen clamping distance can be adjusted according to the requirements, in order to better adapt to the requirements of welding process.

   1, key pressing mechanism: pneumatic lever type structure, to ensure that the workpiece compression tension uniform and welding heat affected zone is uniform, avoiding blow phenomenon; the same row keys closely, between two rows of keys of the distance can be adjustable, to adapt to different workpiece. Electromagnetic valve controlled pneumatic clamping, clamping action quickly, clamping force can be adjusted. Key type gripper workpiece, the longitudinal pressure distribution; by adjusting the key type pressure jaw opening space, applicable to different thickness of stainless steel, Carbon Steel Weldments of I butt welding.

    2, the device has enough rigidity, the device to lift repeatability, reliability, process of good reproducibility.

    3, gun running mechanism: composed of linear guide, ball screw, the slider, servo motor. Torch travel for the realization of automatic welding process, the moving speed is adjustable, can quickly enter the process. The welding dolly installed on the slide blocks, wire feeder, the welding torch adjusting mechanism is installed on the welding carriage, high precision linear guide rail, track, good straightness along the straight guide rail movement.

    4, the torch lifting mechanism: the use of pneumatic actuators, simple and reliable structure, convenient maintenance action reaction timely, torch and workpiece loading and unloading. The welding torch can be carried out in two dimensional adjustment, both vertical and horizontal. The vertical direction adjustment is mainly to adjust the spacing between tungsten electrode head and the workpiece, which set the welding arc length, the voltage of the welding arc. The horizontal adjustment is mainly to adjust the tungsten tip and the joint of. According to the need of welding process, welding torch inclination can change, to weld a satisfactory.

   5, welding core beam: thick walled seamless steel pipe welded components processing, which is provided with a copper liner and processing in the copper pad forming groove, the bottom has a protective gas hole processing, ensure the back protection work in the welding process double-sided molding and heat dissipation and welding, the bottom protective gas is composed of a core beam rear an electromagnetic valve control switch; the core is provided with a positioning plate beam, can ensure the repeatability, reliability of operation of the workpiece positioning. Core beam with a water-cooling device for circulating cooling water, the core of the beam cooling, cooling the welding workpiece. According to the need to be installed in the installing arc device.

      Three, the electric control system:

•      an operation panel, electric control box, and other electronic components. Color touch screen, man-machine conversation, can be multiple sets of parameters preset.
•  
•       parameters controller, the welding power source, the plane, wire feeding machine, water tank, according to the welding process control.
•  
•    the torch walking control using servo control, welding speed (velocity) digital display, welding preset.
•  
•    Manual adjustment and automatic welding of two functions. Core beam hanging ears are in place to protect, hanging ears were not in place, equipment circuit does not act.
   
•    Manual adjustment function, realize the welding torch adjustment of speed, welding torch pneumatic lifting weld of action regulation, manual arc welding, welding parameter adjustment, water circulation box open, wire feeding speed adjustment, the adjustment in the action, action to adjust the pressure plate are individually adjustable.
   
•      Automatic welding, stepping the foot switch once plummet down, stepping the foot switch two times side pressure, step on the pedal switch three, recovery of converter, stepping the foot switch four times, on the other side pressure, step on the pedal switch five, automatic welding torch began to decline after completion of welding, welding torch, rebound, press release, due to unload the workpiece.
   
•     Pause button, press the pause button, stop Welding Torch rally, then press the start button to continue welding torch down;
   
•     Emergency stop button, in case of emergency, can cut off the control and power machine and welding machine; Welding Torch rally, keep pressing plate state all the remaining electric stop all action.
   
•     Panel is provided with a pressing plate state knob, can control the pressing plate state in any state.

Main Technical Choose

     The plate thickness is no more than 6mm, we oftern adopt argon-arc welding and CO2 gas shielded welding
