Introduction to safety measures for inspection and maintenance of machining equipment
Jun 18,2020
We talked about the general requirements for the safety of machining equipment, and I believe the readers should have some understanding of this. Today, we will continue to deepen our knowledge in this area, introducing the following content: requirements for control mechanisms, requirements for protective devices, and requirements for inspection and maintenance. Below, we will discuss these three parts in detail.
The requirements for control mechanisms state that machining equipment must be equipped with protective devices to prevent accidental startup that could pose risks, which is also to ensure the safety of the operator. The control circuit must ensure that no risks occur even if the circuit is damaged.
If the control system is automatic or semi-automatic, it must function to eliminate risks caused by accidents or set up protective devices. If the power supply is accidentally cut off during the operation of the equipment, the actions of braking and clamping must not be interrupted; when the power supply is restored, the equipment must not start automatically. If the equipment poses significant risks, monitoring devices should also be installed.
Requirements for protective devices include two types: safety protective devices and emergency stop switches. Safety protective devices a. Structural requirements: simple structure, reasonable design, edges and flanges must not be sharp. Performance requirements: sufficient reliability, rigidity, and strength within the specified lifespan, good stability, and corrosion resistance.
Safety protective devices should be interlocked with the operation of the equipment, requiring that the equipment cannot start operating before the safety protective devices take effect. Photoelectric, inductive, and other safety protective devices should also be equipped with alarm devices, which can issue warnings when the devices themselves malfunction.
