6 Axis Robotic Press Line Tandem Solution
Our 6-Axis Tandem Solution transforms a series of standalone presses into a fully integrated, autonomous production line. By utilizing articulated robots instead of fixed-path feeders, manufacturers can switch between vastly different part types (e.g., from a flat floor pan to a deeply contoured inner door) with zero mechanical reconfiguration of the transfer system.
The core advantage lies in our Simultaneous Control Logic. We treat the entire tandem line as a single kinematic chain. By slaving the robot's 6th-axis "wrist" to the press's absolute resolver, we achieve a fluid, continuous motion that reduces "wait time" at the die face, maintaining a consistent output of 12 to 15 Strokes Per Minute (SPM).

Tandem Line Application Scenarios
Demonstrating experience in high-complexity automotive stamping.
- Inner & Outer Body Panels: Ideal for hoods, trunk lids, and side-wall reinforcements where parts must be tilted to match the draw angle of the next die.
- Structural High-Strength Steel (HSS): Heavy-payload 6-axis robots provide the rigidity needed to handle heavy, high-tensile parts without vibration.
- Multi-Model Flexible Production: Systems using Automatic Tool Changers (ATC) to switch both dies and robotic grippers in under 10 minutes (SMED).
- EV Large-Scale Components: Handling of integrated "Giga-casting" secondary stamping or large-format aluminum battery housings.
Technical FAQ: The Tandem Advantage
Building Trustworthiness through expert technical comparisons.
Q1: Why use 6-axis robots instead of a 4-axis or 2D-belt transfer system?
Degrees of Freedom. A 4-axis robot is faster in a straight line but cannot "flip" a part. If your part needs to be turned over for a piercing operation or tilted 30° to enter a specific die, only a 6-axis robot provides the "wrist" flexibility required. This eliminates the need for expensive, standalone turnover stations between presses, shortening the overall line length.
Q2: How do you prevent robots from colliding with the press slide during "Continuous Motion"?
We use Interference Zone Predictive Control. The robot controller receives a live feed of the press's crank angle. Using a virtual "Safe Zone" model, the robot begins its entry movement as the slide is still rising (at roughly 270°). If the press speed varies, the robot's trajectory is dynamically adjusted in real-time to maintain a 100mm safety buffer.
Q3: Can 6-axis robots be integrated with older mechanical presses in a tandem layout?
Yes. Our solution includes a Master Line Controller that acts as the "brain" for the whole line. We retrofit older presses with absolute encoders and link them to the robot's PLC via a safety gateway. This "upcycles" traditional mechanical presses into a high-speed, synchronized robotic tandem line.
