Mechanical Press Brake Controls (PRS, RT)
Press brakes are one of the most difficult machine tools to safeguard because of their general purpose-type use in industry. General purpose means a press brake can be used to bend from very small parts to very large parts. Production runs on these machines can be one part to thousands of parts. With this type of operation, press brakes must be versatile.
Today, with advanced technology, it is now possible for industry to safeguard press brakes and maintain the same levels of productivity when the employer (user) considers all components in the press brake system. A complete safeguarded system includes, but is not limited to, the type of press brake, the safeguard itself, tooling to be used, size, shape or configuration of workpiece, material handling, production, maintenance, and any anticipated future needs.
Under OSHA, press brakes are cited for noncompliance in accordance with 29 CFR 1910.212— Machine Guarding, which specifically requires point-of-operation safeguarding. All machines fall under this same regulation where it states: “the safeguarding shall be in conformity with any appropriate standard.” Some states may have their
own rules and regulations for press brakes.
There are several references available on press brake safety; however,
most industries use the ANSI (American National Standards Institute)
B11.3 standard. This standard can be purchased by contacting:
