Shaping Safety Devices TRIZ Cases

Ion sensing inside a feed axis motor identifies cutting liquid intrusion early, helping prevent foreign matter damage and machine tool downtime.

A skewed static guard fits uneven die spaces to block hand access during open-cycle sheet feeding while preserving visibility.

Dual position checks deactivate forming press radiation detectors only at verified tool positions, improving safety timing and reliability.

Dual position checks with correction values deactivate a forming machine radiation detector only at the verified position, improving safety.

A pilot-operated logic valve in a closed hydraulic circuit speeds die cushion pressurization and stabilizes force near bottom dead center.

A moving optical beam and redundant position feedback protect the bending-machine gap and stop tool approach before hand injury occurs.

A movable radiation light barrier tracks the tool position to protect the bending machine working gap without sacrificing usable stroke.

Dual optical safety zones let a bending machine handle non-parallel bend lines while shutting down the upper tool drive when intrusion is detected.

A pilot-operated logic valve and pressure feedback stabilize die cushion pressure faster, cutting servomotor size, cost, and flow disturbance.

Color-coded and conductive wear layers reveal bending tool wear early, enabling planned replacement, axis adjustment, and less scrap.

A controller uses the bending tool tip as a reference to auto-position the light barrier, avoiding unsafe misalignment from incorrect tool data.

A shared cable-coupled adjuster moves press brake transmitters and receivers together, saving space and improving operator-safe positioning.

An adjustable light barrier unblocks the guide rail opening for heavy bending tool changes while preserving safe press operation.

Invalidating photodiodes affected by upper-die shadow expansion helps press brakes avoid false foreign-body detection during bending.

Independent pressure and position cylinders keep the cushion pad pre-pressurized at standby, improving forming accuracy and reducing surge pressure.

Switching beam sensitivity by bending stage and receiver height improves thin workpiece detection without magnet sheet setup.

Back-pressure monitoring predicts hydraulic circuit contamination in a press brake, enabling earlier maintenance and less downtime.

Corrected punch depth combines springback, bending load, and tool deflection to improve press brake angle accuracy.
