Basic knowledge of hardware processing


Hardware processing concept: the raw materials (stainless steel, copper, aluminum, iron...) are machined into various kinds according to the drawings or samples of customers by lathes, milling machines, drilling machines, polishing machines, etc. Parts such as: screws, motor shafts, model car parts, fishing gear accessories

Hardware processing process:

One is to open the material according to the production needs. After the opening, some small parts such as accessories can be punched and then cut or CNC processed. This is a lot in the production of eyeglasses accessories auto parts. The container is made by pressing the punch after the punching, and then spraying after sanding, and then assembling the accessories can be shipped. For small parts, there is still a lot of polished surface treatment, plating or fuel injection. Then the welding or screw assembly and packaging hardware processing safety operation procedures

1. Check whether the moving part is filled with lubricating oil before mechanical work, then start and check whether the clutch and brake are normal, and run the machine for 1-3 minutes. It is strictly forbidden to operate when the machine is faulty.

2. All employees check whether their clothing meets the job requirements before entering the job. Do not wear slippers, high heels and clothing that affects safety. Wear long hats for safety. Maintain a correct posture at work, have sufficient spirit to cope with the work, if you find physical discomfort, you should leave the job immediately and report to the leader. It is necessary to concentrate on the operation, and it is strictly forbidden to talk and cooperate with each other. The operator must not operate under the irritability and fatigue, so as to avoid accidents and ensure safe operation.

3. When replacing the mold, first turn off the power supply, and then stop the operation of the punching moving parts before starting to install and debug the mold. After the installation and adjustment, manually move the flywheel to test twice, check whether the upper and lower molds are symmetrical and reasonable, whether the screws are strong, and whether the pressure ring is in a reasonable position.

4. After the machine is started, it shall be transported by one person and mechanically operated. Others shall not press the electric building or foot pedal switch board, or put the hand into the mechanical working area or touch the moving part of the machine by hand. When working mechanically, it is forbidden to reach into the working area of ​​the slider. It is strictly forbidden to take and place the workpiece by hand. Tools that meet the standards must be used when removing and placing the workpiece in the die. If you find that the machine has abnormal sound or the machine is malfunctioning, immediately turn off the power switch to check.

5. When leaving work, you should turn off the power supply, and arrange the finished products, trims and sundries on the post to ensure the working environment is clean and safe.

Sixth, you must wait for other personnel to leave the mechanical work area, and take the debris on the workbench before starting the power to start the machine.

7. Non-workers are prohibited from entering.

The above operating procedures must be consciously observed, do not operate in violation of the rules, failures, should be repaired with maintenance personnel, immediately turn off the power supply in the event of an accident, keep the on-site report factory waiting until the processing, violation of all the consequences caused by the operating procedures, I assume all responsibility.

Hardware surface processing

Hardware surface processing subdivision can be divided into: metal painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc.

1, surface polishing processing: surface polishing processing is generally used in daily necessities, through the surface burr treatment of hardware products, such as: we produce a comb, the comb is made of stamped hardware, then the combed corners of the comb It is very sharp, we have to polish the sharp part of the corner into a smooth face by polishing, so that it will not cause harm to the human body during use.

2, electroplating: electroplating is also the most common processing technology for metal processing. Through the modern technology, the surface of the hardware is electroplated to ensure that the product does not undergo mildew and embroidered for a long time. The common electroplating processes are: screws, stamping parts, Cell sheets, car parts, trinkets, and more.

3, painting processing: At present, the hardware factory uses the painting process in the production of large pieces of hardware products, through the painting process to prevent hardware from rust, such as: daily necessities, electrical enclosures, handicrafts, etc.
