Precision hardware processing technology and operating specifications
Precision hardware can be cut according to production needs, and then some small accessories can be cut or CNC processed, and precision hardware must be used as a container for cutting and punching, followed by welding, then sanding, and oil injection. After the accessories are made done. It should be reminded that small parts also need to be electroplated or sprayed on the surface after grinding. There are many cases of batch processing of precision metal parts, so the production method and cycle of precision metal processing are different from the operating specifications and processes of general product processing.
Precision metal processing technology:
1. The processing route has great uncertainty. A component or product can have a variety of processes, and the production process requires a wide variety of machinery and equipment and fixtures.
2. Because hardware manufacturing enterprises are mainly scattered processing, the quality and productivity of products depend to a large extent on the technical level of workers, and the degree of automation is mainly at the unit level, such as CNC machine tools, flexible manufacturing systems, etc.
3. The product parts generally adopt the method of combining self-made and outsourced processing. For example, special processes such as electroplating, sandblasting, oxidation, and silk-screen laser engraving will be entrusted to external manufacturers for processing.
4. There are many parts in demand. The workshop site often needs to fill in a lot of material requisitions and will see a "one-line" production order. If there is a process, a lot of process transfer orders need to be filled out.
Specifications for precision metal processing:
1. During product processing. Operators should maintain a correct posture and have sufficient energy to perfunctory operations. If they find physical discomfort, it is necessary to leave the job immediately for personal safety and report to the workshop supervisor or a higher-level leader. It is necessary to concentrate thoughts, stop chatting, and cooperate with each other during operation. The operator should not operate in a state of irritability and fatigue. For personal safety, prevent accidents and ensure safe operation. Before entering the job position, all employees check whether their clothing meets the job requirements. It is forbidden to wear slippers, high-heeled shoes and clothing that affects safety. Those with long hair should wear a helmet.
2. Check whether the moving parts are filled with lubricating oil before mechanical operation, then start and check whether the clutch and brake are normal, and run the machine tool idling for 1-3 minutes, and stop the operation when the machine is faulty.
3. When replacing the mold, first turn off the power supply, and only after the movement of the punch press stops running, can the mold be installed and debugged. After the installation and adjustment, move the flywheel by hand to test twice. In order to prevent unnecessary collision between the machine and the product 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 blank holder is reasonable. position.
4. It is necessary to wait for all other personnel to leave the mechanical work area and remove the sundries on the workbench before starting the power supply to start the machine.
5. During mechanical operation, it is forbidden to put your hand into the working area of the slider, and to stop taking and placing the workpiece by hand. It is necessary to use tools that meet the specifications when picking and placing workpieces in the die. If you find that the machine has abnormal noise or the machine fails, you should immediately turn off the power switch for inspection. After the machine is started, one person will transport the materials and operate the machine. Others are not allowed to press the electric building or step on the foot switch. For the safety of others, they cannot put their hands into the mechanical work area or touch the moving parts of the machine with their hands.
