Overview
The Pascal Traveling Clamp TR Series is an advanced die-clamping system that moves hydraulic clamps automatically to the die via T-slots on the press slide. This technology replaces traditional common plates, improving precision, stability, and die change speed. It’s widely used in stamping (especially automotive) and easily retrofitted to many existing presses.
Key Features
- Eliminates need for common plates — saves cost, space, and reduces time during die changes.
- More stable die mounting in the center of the slide — better precision, especially under heavy load.
- Multiple clamp models & drive options: hydraulic, air cylinder, electric motor.
- Faster clamp travel (especially in newer models) — helps reduce idle time during setup.
- Lighter components (e.g. aluminum base blocks, optimized chain/roller mechanisms) in newer versions for reduced mass and smoother operation.
Models / Variations
Here are some of the main Pascal clamp types, with highlights for when they may be the right fit:
- TRA (Air-cylinder drive) Basic pneumatic/air driven option; reliable performance.
- TRC (Electric motor drive) Suitable for tighter control and perhaps more frequent/demanding operation.
- TRD (Short Stroke) For presses or dies with limited slide travel — compact variants. pascaleng.co.jp
- TRX Electric drive, more compact body. Good where space is constrained or more streamlined layout wanted.
- TR□GX (Quick Maintenance Type) Optional variant that allows hydraulic clamp (TXD) to detach/attach even if installed on the press slide — useful for maintenance or die changes with less downtime.
Typical Specs (Example Range)
- Clamping Force: ~ 39.2 kN, 61.7 kN, 98.0 kN depending on TXD clamp model.
- Clamping Stroke: ~ 8 mm full stroke typical for TXD units.
- Traveling Stroke (Sliding Stroke): 400 mm up to 900-1300 mm depending on model and version.
- Travel Speed: around 0.14-0.30 m/s in many new units. Faster travel reduces setup time.
- Weight / Mass: Newer versions have lighter base blocks; example TRAEX06-0600 had weight reduction (vs earlier) due to design/material changes.
Applications & Use Cases
- Press rooms where die change time, precision, and setup stability are critical (e.g. automotive stamping, high-volume production).
- Retrofits on existing press machines where common plate systems are limiting throughput or precision.
- Operations needing flexible clamping patterns (variable die sizes, multiple U-cut positions) without changing the hardware arrangement every time. tjsolution.com+1
- Environments with frequent maintenance or where minimizing downtime is a major cost driver; quick maintenance variants are helpful.
Considerations for Selection
- Match clamp model (e.g. TXD size) to required clamping force.
- Confirm slide travel & available space for traveling stroke.
- Determine the drive type best suited (air cylinder vs motor vs electric).
- Include sensor / proximity switch features (die detection, backward end detection) for safety and automation. tjsolution.com
- Consider installation constraints: mounting hole layouts, hydraulic / pneumatic supply, control integration, routing of hoses/chains.
Why Pascal TR Series
- Proven reliability — over 120,000 units delivered worldwide. pascaleng.co.jp
- Strong precision and stability thanks to well-engineered mechanical design.
- Reduced downtime and simpler maintenance, especially with newer & quick maintenance models.
- Flexible enough for both new presses or retrofits.
