Problems that should be paid attention to in normal fire prevention in precision machinery parts processing plants

For precision mechanical parts, the processing is very strict, and the processing procedures include feeding and feeding. There are specific requirements for size and precision, such as 1mm plus or minus a few microns, etc. If the size is too wrong, it will become garbage. At this time, it is suitable for reprocessing, which is time-consuming and laborious, and occasionally even makes all processing materials scrapped. This results in an increase in the cost, and at the same time, the parts are definitely not available.

For the processing of precision parts, the main requirements are the size, such as the diameter of the cylinder, there are strict requirements, the positive and negative errors are within the limits of the specified requirements to be qualified parts, otherwise they are all unqualified parts ; There are also specific and strict requirements for length, width and height, and the positive and negative errors are also delimited, such as an embedded cylinder (take a very simple basic component as an example). If the diameter is too large and exceeds the allowable error limit, it will cause, In the case of inability to insert, if the actual diameter is too small and exceeds the lower limit of the allowable negative value of the error, it will cause the insertion to be too loose and the question of not firmness will arise. These are all unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable limit of error. They are all unqualified products and should be scrapped or re-processed, which will inevitably increase the cost.

The above are the requirements for the processing of precision parts, that is, the main size question. It must be processed strictly according to the additional drawings. The actual size of the processed will definitely not touch the surface size of the drawing. Similarly, as long as the processing size is within the allowable tolerance limit, it is a qualified part. Therefore, the requirement for the processing of precision mechanical parts is to process it strictly according to the surface size.

The second is advanced precision parts processing equipment and inspection equipment. Advanced processing equipment makes the processing of precision parts much simpler, with higher precision and better results. The inspection equipment can inspect the parts that do not meet the requirements, so that all products sent to customers can truly meet the requirements.

Precision machinery parts manufacturers should select first- and second-class fire-resistant buildings at the beginning of construction or lease, and other suggested buildings should not be built in the workshop, especially those that are not refractory. Simple building.

For flammable materials such as oil rags and oil cotton yarns that have been used in normal processing. They should be placed in dense metal cylinders (boxes) with a lid and be punished every day.

It is strictly forbidden to apply gasoline, alcohol, etc. on the machine tool in the workshop. The remaining oil after washing the precision parts shall not be placed indiscriminately. Even if it is to be placed, it must be placed in a place with fireproof facilities. It should be poured into the container at the designated address and dealt with in the same way.

Do not store large quantities of gasoline in the workshop. The storage volume of engine oil and kerosene should not exceed one day's consumption. Generally, the required oil is obtained according to the daily demand. and store it in a covered iron bucket. If the storage volume is large, a special oil storage room should be set up. No combustibles should be stored in the oil storage room, and the indoor ventilation should be kept well. The electrical switch should be placed in the outdoor distribution box. And regular maintenance and inspection of electrical appliances, to be foolproof.

In the manufacturing workshop, smoking is definitely not allowed, which is very stressful. Often a small cigarette butt will cause irreparable losses. If you have to smoke, you can go to the smoking area to apply.

If you need to perform open flame welding and cutting, welding and cutting in the workshop, you should first check the surrounding environment, remove the surrounding combustibles, and use refractory materials to cover the nearby machine tools. at the same time. Be sure to designate a special person to be responsible for the investigation and supervision. After the homework is over, the remaining fire should be checked and eliminated, and it must not be careless.

The electrical equipment of the machine tool must be regularly inspected and maintained, and hidden dangers must be eliminated in real time, and it must not be operated with pride. Placement, removal, inspection and commissioning must be handled by professional plumbers according to regulations. All metal enclosures of electrical equipment should have reliable grounding.
