Precision hardware can be cut according to the production demand, and then some small accessories can be processed by Gong cutting or CNC processing, and the precision hardware container must be made by cutting punch, then welding, then sanding and oil spraying. It should be noted that small parts also need to be electroplated or sprayed with oil after grinding. The status of batch processing of precision hardware processing parts is more, so the production method and cycle of precision hardware processing are different from the operation specification and process of general product processing. Next, we Yuwei heavy Technology Co., Ltd. will introduce the precision hardware processing technology and operation specification for you.
Precision hardware processing technology:
1. There is a great deal of uncertainty in the process of processing. A part or product can have a variety of processes, and the production process needs a variety of machinery and equipment and fixtures.
2. Hardware manufacturing enterprises are mainly scattered processing, the quality and yield of products largely depend 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 method of combining self-made and outsourcing processing is generally adopted for product parts. For example, electroplating, sandblasting, oxidation, screen printing and other special processes will be entrusted to external manufacturers for processing.
4. There are many parts in demand. The workshop often needs to fill in a lot of material requisition forms and "one word" production orders. If there is process processing, a lot of process transfer forms need to be filled in.
Operation specification for precision hardware processing:
1. During product processing. The operator should keep the correct posture and have enough energy to perfunctory work. If he finds that he is not feeling well, it is necessary to leave the job immediately and report to the workshop supervisor or higher-level leader for personal safety. During operation, it is necessary to gather ideas, stop chatting and cooperate with each other. The operator should not operate in the state of irritability and fatigue. For personal safety, prevent incidents and ensure operation safety. Before entering the work post, all employees should check whether their clothes meet the operation requirements. It is forbidden to wear slippers, high-heeled shoes and clothes that affect safety. Those with long hair should wear safety helmets.
2. Before mechanical operation, check whether the moving part is filled with lubricating oil, then start and check whether the clutch and brake are normal, and run the machine tool at idle speed for 1-3 minutes, and stop the operation when there is mechanical fault.
3. When replacing the mold, the power supply should be closed first. After the movement Department of the punch stops running, the mold can be installed and debugged. After the installation and adjustment, the flywheel is moved by hand for two times. 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 dies are symmetrical and reasonable, whether the screws are firm, and whether the blank holder ring is in a reasonable position.
4. It is necessary to wait for all other personnel to leave the mechanical operation area and take away the sundries on the working platform before starting the power supply to start the machine.
5. During the mechanical operation, it is forbidden to extend the hand into the sliding block operation area, and to take and place the workpiece by hand. It is necessary to use the standard when taking and placing the workpiece in the die. In case of abnormal sound or machine failure, the power switch should be closed immediately for inspection. After the machine is started, one person will transport materials and operate the machine. Other people are not allowed to press the electric building or step on the pedal switch. For the sake of others' safety, they are not allowed to put their hands into the mechanical operation area or touch the moving parts of the machine with their hands.
The above is the detailed introduction of precision hardware processing technology and operation specifications summarized by yuweizhong technology. Hardware products made of precision hardware are not final consumer goods, but as supporting products of industrial production, there are also some semi-finished products. As long as a small part of precision hardware products are East-West consumer goods. Such as: screw, screwdriver, wrench, fishing gear and so on. Precision hardware accessories are machine parts or components made of precision hardware, or some small hardware products, which can be used alone or as auxiliary appliances.
