Pneumatic Projection Welder Cnc Automatic Piston Rod Resistance Welding Machine
Pneumatic Projection Welder Cnc Automatic Piston Rod Resistance Welding Machine
Product Introduction:
A projection welding machine specifically designed for welding piston rods, commonly used in the production of spare parts in fields such as automobiles, motorcycles, hydraulic and pneumatic systems, engineering machinery, and automotive manufacturing. The device has a wide compatibility range and can accommodate different center distances, piston rod diameters, and ring shapes. After welding, the deformation of the ring is small, the distance between the center of the ring is stable, and there are no obvious marks on the piston rod.

Customized Fixtures and Moving Components: After the equipment is started, it automatically loads, welds, and unloads, achieving fully automated unmanned operation and greatly improving efficiency. The device is compatible with different pole lengths and can be switched through servo without the need for additional adjustments.
Independent Vibration Disc: The equipment is equipped with an independent vibration disc that can hold 500 workpieces, ensuring that the equipment does not require manual assembly for 2 hours. Equipped with fully automatic welding, the production capacity can reach 720pcs/h.
Human-computer Interaction Interface: Through touch screen or physical buttons, operators can intuitively adjust welding parameters, store and call hundreds of process formulas; The system displays dynamic curves in real-time and automatically records welding data to support quality traceability; Simultaneously integrating fault diagnosis, permission management, and IoT communication functions, significantly improving welding consistency.
Waterway Components: All waterway components undergo surface treatment to prevent rusting, and waterway drainage is independently discharged to the water tank. Based on the outflow situation, blockages in the waterway can be observed and eliminated.
