Robotic Stamping Line With Quick Die Change System Press-to-Press Transfer Robot
To maximize the efficiency of a Tandem Press Line, the synergy between the Press-to-Press Transfer Robot and the Quick Die Change (QDC) system must be absolute. Zhejiang Qicheng Intelligent Technology specializes in this high-speed integration, utilizing ABB's dedicated stamping software (StampWare) to manage the complex spatial handovers between presses while preparing for the next product run in parallel. This "Seamless Flow" architecture ensures that the transition from the last part of "Batch A" to the first part of "Batch B" is measured in minutes, not hours.
Press-to-Press Transfer Robot with Integrated QDC
High-Velocity Synchronization by Zhejiang Qicheng Intelligent Technology
In a high-volume tandem line, the Press-to-Press Transfer Robot is the critical link. Zhejiang Qicheng Intelligent Technology deploys 6-axis ABB IRB 6700 and 7600 robots specifically tuned for "Inter-Press" movement. These robots don't just move parts; they communicate with the Quick Die Change (QDC) system to facilitate automated tooling swaps, ensuring that the physical transfer path and the die geometry remain perfectly aligned through every product changeover.

Technical Pillars of Integrated Transfer & QDC
Dynamic Path Optimization (StampWare): The transfer robot utilizes ABB's StampWare to "shadow" the press ram. As the die opens, the robot enters the work zone at a calculated trajectory that minimizes the distance between the pick point in Press 1 and the place point in Press 2. This continuous motion reduces cycle time by up to 20% compared to standard point-to-point robotics.
Automated End-of-Arm Tooling (EOAT) Exchange: A QDC system is incomplete without automated robot tooling. We integrate Automatic Tool Changers (ATC) on the robot's wrist. During a die change, the robot parks its current "Batch A" gripper in a protected rack and retrieves the "Batch B" gripper. The pneumatic and electrical connections are made instantly via blind-mate couplings, verified by the PLC before the first stroke.
Smart Bolster & Robot Interlocking: Our control architecture treats the press's moving bolsters and the robots as a single kinematic group. When the "Changeover" command is initiated, the robots move to a "Safe Home" position that clears the path for the moving bolsters. Once the new dies are clamped, the robots perform a high-speed "Zero-Point Check" to confirm the new die's coordinates before starting production.
Inter-Press Orientation Control: Many automotive parts require a 90° or 180° flip between the draw and trim stages. Our 6-axis transfer robots perform this orientation change during the transfer flight. This eliminates the need for standalone "turnover" machines, reducing the line's total footprint and electrical complexity.
Key System Highlights
Vibration-Dampened 7th Axis: For large gaps between presses, the transfer robots are mounted on high-speed linear tracks. These tracks feature active vibration suppression to ensure the robot's TCP (Tool Center Point) remains stable at ±0.05mm.
Real-Time Interference Monitoring: A digital twin of the die geometry is loaded into the robot's controller. The robot continuously calculates its distance from the die walls and the moving ram, preventing collisions even during high-speed manual overrides.
Energy-Efficient Trajectory Planning: The system automatically calculates the most energy-efficient path for the robot during the transfer, utilizing regenerative braking to capture power during the deceleration phase of the "Place" move.
Industry Q&A (Transfer & QDC Integration)
Q: How does the system handle "Double-Sheet" detection during the transfer phase?
A: While primary de-stacking handles initial separation, our transfer robots are equipped with Integrated Vacuum Flow Sensors. If the robot detects an anomalous vacuum level (indicating a partial double-sheet or a drop), it immediately halts the press cycle and executes a "Reject Sequence" to a designated scrap chute, protecting the dies from damage.
Q: Can the QDC system be retrofitted to an existing tandem line with older robots?
A: Yes. We specialize in Automation Upgrades. We can integrate our QDC control logic and automated tooling racks with existing robot fleets, provided they have the payload capacity. This significantly increases the ROI of your older assets by adding modern agility.
Q: What happens if the new die is slightly misaligned after the moving bolster locks?
A: We employ Search-and-Seat Logic. Upon the first entry into a new die, the robot uses an inductive "search" sensor on the EOAT to find the die's reference pins. The robot then offsets its entire motion program to match the physical die location, ensuring perfect alignment without manual intervention.
