Punch Press, Press Brake & Area Safeguarding

Point of Operation Safeguards, Devices and Controls

Production Resources offers a complete line of ANSI and OSHA compliant power press clutch/brake controls, light curtains (presence sensing devices), sliding barrier devices, barrier guards, pull outs, restraints, riveter guarding devices, safety mats, safety/die blocks, and area/perimeter guarding devices.

We can help you select the right safeguard for your power press, press brake, fabricating equipment, coil line, and/or robotic work cell. Proper safeguard selection is vital not only to operator safety but productivity as well. It’s important to properly identify the hazard, how the operator and others are exposed, frequency of exposure, and the nature and probability of injury. Operator interaction with the machine, stroke/cycle initiation means, part loading/unloading procedures, stopping performance, and passersby exposure must all be considered.

Control system design must also be considered as part of any safeguarding solution. Adding a safeguard to a machine with a poorly designed control or one non-compliant with safety standards is dangerous. When a safeguarding system sends a stop command the machine control system must respond instantly. A control failure must be recognized such that safety is not compromised. Safety systems are often compromised by poor maintenance, bypass schemes, or other system alternations. When a control system is modified, changes – especially electrical wiring – must be done safely and documented.

Our Application Engineers have working knowledge of the ANSI power press standards (B11.1), hydraulic press standards (B11.2), and press brake standards (B11.3) as well as OSHA regulations 1910.212 and 1910.217. They can help you determine if your machines are in compliance and recommend the safest and most productive guarding solutions.

Die Doors

Pax Die Door

Pax Die Door

Pax die doors are point of operation safeguarding devices for mechanical power presses. They are best suited to coil fed and/or automatic operations and prevent the operator from entering the work area while the press is running as the doors are interlocked with the press stop circuit. Additionally they contain fluids and flying objects.

Pax die doors help you maintain a clean and safe workplace. Models are also available to help you control sound pressure levels.

WireCrafters Perimeter & Area Barrier Guarding Devices

Physical barrier guards should be considered as a safeguarding solution where frequent access and/or maximum visibility to the operation or process is not of major importance. Often a barrier guard may be combined with other safeguarding solutions, such as presence sensing devices, to create a more flexible and complete guarding solution.

We offer woven and welded wire physical barriers from WireCrafters. These barriers are a practical, easy to use/maintain, affordable guarding system for robotic cells, automated work cells, and general purpose perimeter guarding applications.

PRI can help you configure a guarding system to meet your specific needs. We have experience in configuring practical safeguarding solutions without harming productivity.

Press Brake Guarding

Protech Systems integrates Eagle Eye light curtains with control systems designed specifically for use with press brakes. Systems are available to work with friction clutch treadle operated machines, air clutch machines, and hydraulic machines. Programmable beam blank out features allow the light curtain to accommodate bending profiles in sync with CNC back gauges for box, tray, or other complex bending applications.

The light curtain ignores objects of 3/8” or less so flat sheet air bends are easily accomplished. For box forming, tray forming, and similar operations where the part flange interrupts the light curtain, the programmable beam blank out feature is used.

Small short part forming is accommodated using a stroke stop feature.

LazerSafe press brake guarding

LazerSafe press brake guarding

These systems range in price from $7,500 to $15,000 depending on features and whether provision for new motor controls are required.

LazerSafe press brake guarding is specifically designed for use with fast stopping hydraulic press brakes where it’s necessary to hold short work pieces close to the tooling. This system is applicable to newer press brakes with “creep speed” provisions.

Typical LazerSafe systems start at $13,000 installed.

Pull Backs – Pull Outs – Hold Backs – Restraints

Press Brake Holdout System

Press Brake Holdout System

Pull-backs and restraints press safety systems either prevent an operator from reaching the point of operation or pull the operator away from the point of operation as the ram/slide moves down. Operators wear wristlets attached to straps that are fixed to the restraint or pull out mechanism.

Overhead restraint hold-out systems are available for press brake specific applications. These devices accommodate single or multiple operators.

The primary advantage of hold out systems is the relatively low cost compared to light curtain guarding systems. However, the devices must be inspected prior to each operator change, die change, and shift change. Furthermore the operator is tethered to the machine and must unstrap and strap back up when it’s necessary to leave the operation or do another task. Operators are sometimes unreceptive to this guarding alternative and require supervision to ensure proper use.

Riveter Safeguarding Devices

Positive Safety Touch o Matic

Positive Safety Touch o Matic

 

 

Drop ring safeguarding devices provide economical, simple to understand and use, reliable protection for an operator’ finger and hand protection while using riveter guards, spot welders, staking presses, or similar devices. These devices employ a mechanical assembly with a “drop ring” that gravity falls around the point of operation before the machine cycle.
