Code of practice for precision hardware processing

Operating specification for precision hardware processing:

1, product processing. Operators to maintain the correct posture, to have enough energy to perfunctory work, such as physical discomfort, in order to personal safety, it is necessary to immediately out of the job, and to the workshop supervisor or higher level of leadership. When operating, it is necessary to gather ideas, stop idle talk and cooperate with each other. The operator should not operate in a state of irritability and tiredness. In order to ensure personal safety, prevent incidents and ensure safe operation. All workers before entering the job, check whether their clothes meet the requirements of the job. Do not wear slippers, high heels and unsafe clothing, long hair should wear a helmet.

2. Check whether the moving part is filled with lubricating oil before mechanical operation, then start and check whether the clutch and brake are normal, and run the machine tool empty for 1-3 minutes, and stop the operation when there is a mechanical fault.

3. When replacing the mold, the power supply should be closed first, and the installation and debugging of the mold can only be started after the punching press movement department stops running. After installation and adjustment, move the flywheel twice by hand. In order to prevent unnecessary collision between machinery and products to be processed, it is necessary to check whether the upper and lower molds are symmetrical and reasonable, whether the screws are firm, and whether the holder ring is in a reasonable position.

4. It is necessary to start the power supply to start the machinery after all the other personnel are out of the mechanical operation area and take away the debris on the operation table.

5. During mechanical operation, it is forbidden to reach into the slider operation area and to take and release work parts by hand. It is necessary to use conforming things when taking and releasing workpieces in the die. If abnormal sound or machine failure is found, the power switch should be closed immediately for inspection. After the machine is started, one person shall transport the material and operate the machine. Other people shall not press the electrical construction or step on the foot switch plate. For the safety of others, hands shall not be placed in the mechanical operation area or touch the moving part of the machine with their hands.

The hardware products produced by precision hardware are not final consumer goods, but as industrial products, there are also some semi-finished products. Only a small proportion of precision hardware products are consumer goods. Such as: screws, screwdrivers, wrenches, fishing gear and so on. Precision hardware accessories are machine parts or components made of precision hardware, or some hardware products, which can be used alone, or can be used as assistance tools.
