Cable tray inside the welding machine

Cable trays in welding machines are produced and managed using automated wire feeding, pneumatic welding, and servo-controlled systems to ensure precise, high-quality mesh panels.Internal Mechanism of Cable Tray Welding MachinesCable tray welding machines, such as those from DAPU and RKM, are designed to manufacture metal mesh panels for cable trays used in electrical, industrial, and construction applications . Inside the machine, the process involves several coordinated systems:Longitudinal Wire Feeding: Servo motors control the precise movement of longitudinal wires into the welding area, ensuring accurate spacing and alignment .Transverse Wire Positioning: Pneumatic cylinders or SMC air cylinders accurately place cross wires into the welding system, maintaining consistent mesh patterns .Welding System: Advanced pneumatic welding technology applies uniform electrode pressure to join wires, producing strong, flat, and reliable mesh panels. Some machines can weld two panels simultaneously for higher efficiency .Mesh Pulling and Clamping: Servo motors and planetary reducers pull the welded mesh forward with minimal error, while air cylinders clamp the mesh to maintain stability during welding .Automation and ControlThe entire process is typically controlled by PLC systems from brands like Siemens or Schneider, allowing operators to adjust wire spacing, mesh size, and welding speed . The automation ensures high-speed production with consistent quality, reducing manual intervention.Maintenance ConsiderationsInside the welding machine, cable trays and wires require regular maintenance to ensure smooth operation:Clean dust and debris from gaps around transformers, reactor coils, and power semiconductors.Inspect power wiring connections and ensure the cable drag chain is free from obstructions .Regularly check pneumatic cylinders and servo motors for proper function to maintain precise wire placement.Integration with Bending SystemsAfter welding, the mesh panels are often transferred to a cable tray bending machine, which shapes the panels into the final tray form according to required angles and dimensions . This integration ensures a seamless production line from wire feeding to finished cable tray.SummaryInside a cable tray welding machine, the cable tray is formed from raw wires using a combination of servo-controlled feeding, pneumatic positioning, and automated welding, all coordinated by PLC systems. This setup guarantees high-quality, durable, and precise cable tray mesh, suitable for industrial and commercial wiring applications .
