The CNC steel bar cage welding workstation is based on a servo synchronous rotation system combined with a welding manipulator to achieve automated forming. It is the core equipment for centralized processing of steel bars in pile foundation and bridge prefabrication projects. After the main bars are clamped and positioned, the dual-end servo axes work collaboratively to drive the cage to rotate at a constant speed. The numerical control system matches the rotational angular velocity with the mechanical hand's movement displacement in real time, ensuring that the welding gun precisely tracks the intersection points of the main bars and spiral hoops, eliminating synchronization deviations and ensuring the stable and controllable roundness and pitch accuracy of the cage body.
The machine comes with multiple built-in welding programs, allowing operators to switch between two mainstream welding processes, full welding and skip welding, with a single click.
In full welding mode, all intersections between the longitudinal bars and stirrups are continuously welded, providing high weld strength. This mode is suitable for demanding working conditions, such as high-load applications and Class I pile foundations.
Skip welding, on the other hand, uses an intermittent welding pattern, in which selected intersections are welded at intervals. While meeting the applicable structural acceptance requirements, this process reduces welding heat input and minimizes the risk of rebar cage deformation. It also shortens welding time and reduces consumable consumption, making it suitable for the batch production of conventional pile foundations and retaining piles.
The entire process is uniformly controlled by the PLC. The welding gun posture, welding current, and holding pressure time can all be digitally set. The weld points have uniform fusion cores, avoiding problems such as false welding, missed welding, and uneven weld seams in manual welding. A single operator can complete the loading of materials, parameter invocation, and the cutting of finished products, significantly reducing reliance on labor. This workstation can be connected to the CNC bending center and the shearing production line to form a complete steel bar processing line, matching the standardized prefabrication requirements of overseas infrastructure projects.
