Safety precautions for bending machines include the following:

1. Preparation before operation:

- The operator must be professionally trained and familiar with the structure, performance and safe operation procedures of the bending machine.

- Before operation, wear personal protective equipment, such as safety helmet, protective glasses, gloves, etc.

2. Machine inspection and maintenance:

- Before use, the bending machine must be fully inspected to ensure that it is in good working condition.

- Regular inspection and maintenance of the press, including lubrication system, electrical system and mechanical components, to ensure its normal operation.

3. Safe operation:

- During operation, it is strictly forbidden to extend the hand or other parts of the body into the working area of the bending machine to prevent clamping or crushing.

- It is forbidden to adjust or repair the bending machine while it is running, and relevant work must be carried out after the machine is completely stopped.

- Strictly follow the operating procedures of the bending machine, and do not change or omit any steps without authorization.

4. Material handling:

- When placing and removing the workpiece, ensure stability and safety to prevent the workpiece from slipping or rolling and causing injury.

- Avoid bending with inappropriate materials or plates that exceed machine specifications to prevent machine overload or damage.

5. Emergency handling:

- In the process of operation, if you encounter abnormal conditions or machine failure, you should stop the machine immediately and report to the relevant personnel for handling.

- Be familiar with and master the position and use of the emergency stop button or switch of the bending machine, so as to be able to stop quickly if necessary.

6. Safety protection device:

- Ensure that the safety protection devices of the bending machine (such as photoelectric protection devices, safety doors, etc.) are intact and working properly.

- Do not remove or bypass safety protection devices at will.

7. Working environment:

- Keep the work area clean and orderly, avoid debris, oil pollution, etc., which may cause interference or safety risks to the work.

- Ensure that the work area has good lighting and ventilation so that the operator can clearly see the work situation and respond to emergencies in a timely manner.

Following the above safety precautions can effectively reduce the safety risk during the operation of the bending machine and ensure the safety of the operator and the normal operation of the machine.
