Robot Integrated Stamping Line Tandem Press Line
For Robot Integrated Stamping Lines and Tandem Press Lines, the technical objective is the flawless synchronization of multiple autonomous cells into a singular, high-speed production stream. Zhejiang Qicheng Intelligent Technology excels in "Total System Integration," ensuring that the ABB robotics, the heavy-duty presses, and the inter-press transfer logic operate as a unified, data-driven entity. By removing the mechanical constraints of traditional transfer bars, our integrated tandem lines provide the 6-axis flexibility required to process complex automotive and industrial geometries at industry-leading Strokes Per Minute (SPM).

The Architecture of Integration
- Seamless Press-to-Robot Handshaking:
True integration starts with the "Crank Angle Sync." Our control systems monitor the exact position of the press ram in real-time. This allows the ABB IRB 6700 or 7600 robots to begin their entry into the die area while the ram is still on its upward stroke, maximizing the "open-window" time and significantly increasing the line's total SPM.
- Multi-Robot Coordination (MultiMove ™):
In a tandem line, multiple robots must work in the same physical space without collision. We utilize ABB MultiMove ™ technology, allowing up to four robots to be controlled by a single drive module. This ensures that the de-stacking robot, the feeder robot, and the inter-press transfer robots move in perfect, collision-free harmony.
- Vibration-Isolated Foundation Engineering:
Integrated lines face extreme mechanical stress. Qicheng designs High-Rigidity Mounting Pedestals that are engineered to decouple the robot's high-precision encoders from the seismic shocks generated by 2000T presses. This preserves the robot's ±0.05mm repeatability over millions of cycles.
- Unified HMI (Human-Machine Interface):
We simplify the complexity of a 50-meter production line into a single, intuitive touchscreen interface. Operators can monitor the health of every robot, the tonnage of every press, and the status of every safety sensor from a centralized command center, reducing the need for specialized robotic technicians on every shift.
Key System Highlights
- Automated End-of-Arm Tooling (EOAT) Management: Integrated "Tooling Centers" where robots automatically swap their grippers during a die change, ensuring the line is ready for a new product part-number in under 5 minutes.
- Digital Twin Pre-Commissioning: We utilize RobotStudio ® to create a complete digital replica of your tandem line. Every movement is validated in the virtual world to ensure zero interference before the first robot is bolted to your floor.
- Intelligent Scrap & Part Sorting: At the end of the tandem line, integrated robots handle the high-speed sorting of finished parts into racks while simultaneously managing the automated removal of scrap material.
Industry Q&A (Integration Focus)
Q: How do you manage the "Bottleneck" station in a 5-press tandem line?
A: Our Flow-Optimizer software analyzes the cycle time of each station in real-time. If Station 3 is slower due to a complex draw, the system automatically adjusts the acceleration of Robots 2 and 4 to "buffer" the movement, preventing the entire line from stopping and ensuring a smooth, continuous flow.
Q: Can your integrated line handle "Multi-Part" stamping (two parts per stroke)?
A: Yes. We design Dual-Grip EOAT and specialized "Part-Splitter" logic. The robot can pick two smaller blanks simultaneously, load them into a double-cavity die, and then extract the two finished parts into separate out-feed racks without decreasing the SPM.
Q: What happens if one robot in the integrated tandem line requires maintenance?
A: Our Bypass Mode allows the line to continue operating (at a reduced speed) while a single cell is safely isolated for maintenance. Because the system is "Integrated" rather than "Rigid," the remaining robots can adapt their paths to bridge the gap, maintaining production while repairs are made.
