What are the safety requirements for mechanical processing equipment

1. Material


The materials used in the machining equipment itself should meet the safety and health requirements, and materials that are harmful to the human body and materials that have not been tested for safety and health are not allowed.


Two, appearance


The shape and structure of the machining equipment should be as smooth as possible, avoiding sharp corners and edges.


Three, processing area


1. Effective protective measures should be taken for equipment prone to injury accidents in the processing area.


2. Protective measures should ensure that the equipment prevents any part of the operator's body from entering the dangerous area when the equipment is working, or when entering the dangerous area, ensure that the equipment cannot run (line) or make an emergency brake.


3. The following protective measures shall be adopted for mechanical processing equipment alone or at the same time:


(1) Completely fixed, semi-fixed airtight cover;


(2) Mechanical or electrical barriers;


(3) Mechanical or electrical interlocking device;


(4) Automatic or semi-automatic feeding and discharging device;


(5) Hand limiter, hand release device;


(6) Mechanical or electrical two-hand release device;


(7) Automatic or manual emergency stop device;


(8) Limiting devices that cause dangerous strokes, feeding or feeding;


(9) Prevent misoperation or misoperation of the device;


(10) Warning or alarm device;


(11) Other protective measures.


Four, moving parts


1. All moving parts that are likely to cause injury accidents should be closed or shielded, or other protective measures should be taken to avoid operator contact.


2. Based on the plane where the operator is standing, all transmission devices with a height of less than 2m must be equipped with protective devices, and material conveying devices and belt transmission devices with a height of more than 2m should be equipped with protective devices.


3. In order to avoid crushing injury, the distance between linear moving parts or between linear moving parts and stationary parts must comply with the regulations.


4. Mechanical processing equipment should be equipped with reliable limit devices as required.


5. Mechanical processing equipment must be equipped with overload safety devices for parts that may be damaged due to overload.


6. Moving parts that rotate at high speed should undergo necessary static or dynamic balance tests.


7. The moving parts with inertial collision must take reliable buffer measures to prevent injury accidents caused by inertia.


Fifth, working position


1. The working position of the machining equipment should be safe and reliable, and should ensure that the head, hands, arms, legs, and feet of the operator have enough space for activities that meet the psychological and physical requirements.


2. Machining equipment should preferentially adopt easy-to-adjust work chairs to increase the comfort of the operators and facilitate the operation.


3. The working position of the machining equipment should ensure the safety of the operator, the platform and passage must be non-slip, and the pedals and railings should be set if necessary,


4. The mechanical processing equipment should be equipped with local lighting devices with safe voltage.


VI. Emergency stop device


1. If the machining equipment has the following conditions, it must be equipped with an emergency stop device.


2. The machining equipment that needs to be equipped with an emergency stop device should be equipped with an emergency stop device in every operating position and where it is needed.


Seven, noise


The noise index of mechanical processing equipment should be lower than 85dB(A).


Eight, fire and explosion protection


Mechanical processing equipment should adopt fire-proof and explosion-proof technical measures according to the conditions of use and the needs of the environment.


Nine, electrical installations
