SOLUTION 03 · PRESS BRAKE SAFETY
Laser safety systems for press brakes.
Explore DSP, MSD, SDKELI and LN protection references, sensing-zone diagrams and installation examples. The final safety function must be matched to the machine, tools and production task.
01 · DSP LASER PROTECTION
A sensing zone that follows the upper tool.
The DSP reference places a monitored area beneath the moving upper tool. During the fast approach, an object entering that area is detected before it reaches the tool tip; the device signal must then be handled by the press brake’s verified safety function. Tooling, part shape and stopping performance determine the final arrangement.
Important boundary Never install, alter, validate or bypass a safety function based on this page. Follow the approved device documentation and the qualified machine-safety process.
DSP PROTECTION AREA
Three sensing-zone diagrams
These manufacturer reference drawings explain how the front, central and rear areas may be considered. They are not operating instructions; any mode and blanking setting require a qualified, task-specific safety assessment.
02
Profile clearance mode
A reduced sensing arrangement can be considered for formed or boxed parts only after a task-specific safety review.
03
Rear-zone exclusion
The diagram illustrates another reference zone arrangement; its permitted use must be confirmed for the actual machine and process.
DSP DEVICE & INSTALLATION
Review the sensor, mounting and stopping function as one system.
The reference device is mounted close to the press-brake tooling so its detection field can move with the upper beam. The usable mode, sensing distance and stop response must be checked against the selected device documentation and the actual machine.
- Tool-tip detection area and part clearance
- Sensor alignment, brackets and cable routing
- Machine control interface and validated stop performance
02 · SINGLE-BEAM REFERENCE
MSD laser safety system
The MSD reference uses a visible laser beam between a transmitter and receiver. An interruption inside the defined detection area is passed to the machine safety system, which must be designed and validated for the particular press brake.
- Transmitter and receiver define the detection path
- The detection area must be assessed against tooling and workpieces
- Stopping behavior depends on the complete machine safety circuit
03 · TOOL-AREA REFERENCE
SDKELI laser safety system
The SDKELI reference places a laser-sensing arrangement close to the moving upper tool. Its controller, sensing field and mounting position are reviewed with the actual tool geometry and machine interface.
- Tool-tip clearance and beam position require confirmation
- Sensor movement must be coordinated with the upper beam
- Control and feedback interfaces are verified in the full safety design
04 · PHOTOELECTRIC REFERENCE
LN laser safety system
The LN reference focuses on monitoring the upper-tool tip area where the operator approaches the bending zone. Selection has to balance access, part handling and the verified stopping behavior of the press brake.
- Assess the tool-tip detection area for each representative task
- Confirm mounting space and the machine safety interface
- Document the final configuration and validation before use
ASSESSMENT CONTEXT
Different workpieces can change the safety review.
Start with the task that most closely represents your daily production. The selected context organizes the evidence needed for an engineering discussion; it does not define a safety operating mode.
01 · SELECTION REVIEW
Standard bending tasks
Review the recurring tooling, part size and expected production rhythm before selecting any tool-area protection arrangement.
Bring these inputs to the review
- Upper and lower tooling envelope
- Documented stopping performance and safety function interface
- Operator access and material-handling path
SAFETY PROJECT INPUTS
Prepare a safer, clearer technical review.
Share the press-brake model, year, tooling information, representative parts, existing safeguarding, drawings, photos and the applicable market or project requirements. GWMT can then discuss the appropriate next technical review.
