4 axis CNC automatic welding machine

Workpiece:

1.Welding workpiece:for length 3m,width 1m

2.Thickness:1.2-2mm

Welding Requirement:

1.Meet the requirement of U type seam welding.

2.Welding seam will be flat welding or fillet welding.

3.Weldingprocess does not allow the pore,crack,incomplete penetration, crater, burnt, slag, broken welding and other welding defects.

4.Welding seam doesnot leak. Little spatter and smooth welding surface.

Tech Parameters

Machine Main Characteristics

1.Welding torch moves, workpiece is fixed.

2.4axis CNC, realize right&left,forward&backward,up&down and rotation movement.

3.Workpiece is held and positioned by jig and fixture.

4.Machine is with high welding voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine is also with low welding voltage and low welding current for filling crater.

5.Push-type wire feeder works stably.

6.Welding torch can be adjustable at vertical direction.

7.4axis CNC system controls whole machine operation.Welding parameters and mode switch can be setup in one integrated control panel. System can save at least 100pcs welding programs.Programs can be directly called by inputting corresponding serial number.Programs can be locked with password.

8.Welding torch can be adjusted up and down, side to side and angled turn.

9.Machine can work continuously for 24-hour.

Machine Composition

Machine consists of body,4axis control system,working table,electric conduction mechanism,electrical control system, power source and pneumatic system.

1. body:

machine body is welded with square tube and thick steel.In order to avoid structural distortion, machine body is processed by Vibrating Stress Relief (VSR).

2. right and left moving mechanism:

It is driven by AC servo motor. With the help of serve motor reducer and rack &pinion,sliding plate will move on square rails.

3. up and down moving mechanism:

It is driven by AC servo motor. With the help of serve motor reducer and ball screw,sliding plate will move on rails.

4. forward and backward moving mechanism:

It is driven by AC servo motor. With the help of serve motor reducer and rack&pinion,gantry will move on sliding plate.

5. welding torch rotation mechanism:

It is driven by AC servo motor. The angle of mechanism can adjusted manually, and locked tightly.

6.jig and fixture:

installed in the working table,fix workpiece through cylinder. Jig and fixture include height adjustment mechanism.Pneumatic positioning device is used to fix workpiece correctly, and guarantees welding reliability.

7. control system:

Programs can be directly called by inputting corresponding serial number.Programs can be locked with password. System can save at least 100pcs welding programs.After setting up parameters, programs can be run immediately once we press start button.

Machine is with high welding voltage and slow wire feeding performance, which guarantees reliable arc igniting. Machine is also with low welding voltage and low welding current for filling crater.

8.Welding power source

China AOTAI pulse NBC-350P welding power source.
