Automatic Vertical Gas Cylinder Nut Circumferential Welder

 

 

1.AC Motor:

The AC motor equipped on this welding machine is primarily used to drive the welding torch to rotate stably and precisely along the circumferential seam of the gas cylinder nut. This type of motor is robust and easy to maintain, providing smooth and reliable continuous rotational power. Its operation is precisely regulated by the control system to ensure that the welding torch maintains a constant linear speed and stable trajectory during circumferential seam welding, thereby achieving uniform and high-quality weld formation.

2.Cooling Fixture:

The cooling fixture for the circumferential seam welding machine for air reservoir nuts primarily employs a circulating water cooling system. Through cooling water channels built into the fixture, it achieves rapid cooling of the welding area. This fixture is typically made of copper to optimize thermal conductivity and fits tightly to the nut structure, ensuring efficient heat dissipation during welding. This controls workpiece deformation, stabilizes weld quality, and extends equipment lifespan.

3. The wire feeding mechanism

The wire feeding mechanism is driven by a precision servo motor and equipped with a high-precision reducer to achieve stable and precise control of the welding wire speed. The mechanism is typically equipped with an active wire feeding wheel design to ensure stable and reliable wire feeding force and effectively prevent slippage or jamming. The wire feeding guide is made of low-resistance, wear-resistant material, and its path is optimized to reduce friction, ensuring the welding wire reaches the welding torch smoothly.

4.The actuator of this special machine is cylinder-driven, mainly achieving two core actions: first, controlling the lifting and lowering movement of the welding torch to accurately reach and complete the circumferential welding of the air reservoir nut; second, driving the oil nozzle clamping mechanism to ensure the workpiece is firmly clamped during the welding process. The actions of the cylinders are all centrally controlled by a pneumatic rotary valve. The operator can switch the air path by turning this valve, thereby directly and reliably commanding the cylinders to complete the reciprocating motion of extending or retracting, achieving a continuous operation of the welding torch's up-and-down movement and clamping/releasing.

5.Welding Torch 

The welding machine employs argon arc welding and is equipped with a highly stable welding torch. This torch features a precisely centered high-purity tungsten electrode and integrates a highly efficient wire feed mechanism. This wire feed mechanism works in conjunction with the welding torch to continuously and evenly deliver welding wire to the molten pool during the welding process.

6.Control system

Japan OMRON PLC and touch screen are used to control the whole machine. With the help of touch man-machine interface, welding mode and specification can be preset, stored and retrieved. There will be fault alarm and indication during welding process, such as stuck wire, blocked wire, etc.

7.Welding power source and chiller 

High-performance digital TIG welding power supply: Features precise current control (such as slow rise/fall and pulse welding functions). Pulse welding is crucial for controlling heat input, reducing deformation, and improving weld penetration consistency. The chiller is primarily used for circulating cooling during the welding process. This tank is connected to the welding torch's cooling circuit via a built-in water pump, continuously circulating cooling water during welding. This effectively removes the high temperatures generated by the welding torch during prolonged operation, ensuring the torch temperature remains stable within a reliable operating range.

 1.Loading: The operator places the nut to be welded and the gas cylinder end cap into the tooling position on the equipment.

 

 2.Clamping and Positioning: Rotating the pneumatic manual valve automatically centers and clamps the workpiece.

 

 3.Starting Welding: The operator selects the corresponding program on the touchscreen and presses the start button.

 

4.Automatic Welding:

• The welding torch automatically moves to the welding point.
• Pre-supply of gas.
• High-frequency arc ignition or lifting arc ignition.
• The welding torch rotates at a preset speed, the welding power supply outputs current according to the program, and the wire feeder feeds wire synchronously.
• After one revolution (360°) of welding, the current automatically decays to fill the crater, the welding torch is lifted, and gas is stopped after a delay.

 

 5.Unloading: Rotating the pneumatic directional valve in the opposite direction lifts the welding torch, and the operator removes the workpiece, completing one cycle.

 

 

Selection and Customization Considerations,we need you to provide your welding requirements so that we can offer you a more professional welding solution:

• These specialized machines are mostly non-standard customized equipment. Users need to specify the following technical parameters when purchasing:
• Workpiece Range: Cylinder diameter, height, weight.
• Nut Specifications: Dimensions, material (carbon steel, stainless steel, aluminum alloy, etc.).
• Welding Process Requirements: Weld size (weld leg height), whether internal and external welding is required, whether full penetration is required, etc.
• Production Cycle Requirements: Expected hourly or daily output.
• Automation Level: Whether it needs to be integrated with loading/unloading robots or production lines.

 

 

1.Normally we will use fumigation plywood case for packaging; for some big machine, we can use steel pallet and plastic filme cover.All machines are paint with anti rust paint or oil before leaving factory.
2.Package can be as customers' requirement.
