Hardware processing is to raw materials (stainless steel, copper, aluminum, iron. ...). , lathe, milling machine, drilling machine, polishing and other machinery according to customer drawings or samples processing into a variety of parts, such as: screws, motor shaft, model car parts, fishing accessories, speaker products shell, mobile power shell, etc..
Process:
Hardware processing process is according to the production needs to open material, open after some such as small parts of the production can go to the punch and then gong cutting or CNC processing, which in glasses accessories, auto parts production a lot. And do container: is to open the punch to burn welding, and then sand after oil injection, and then assemble the accessories can be shipped. And for hardware gadgets, there are a lot of polished surface treatment, plating or oil spraying. Then burn welding or screw assembly packaging shipment.
Operation steps:
1. All employees shall check whether their clothes meet the work requirements before entering the work post. Do not wear slippers, high heels and safety clothing, long hair to wear a helmet. Keep the correct posture while working, and have enough spirit to cope with the work. If you feel unwell, you should leave the work post immediately and report to the leader. It is forbidden to chat and cooperate with each other during operation. The operator should not operate in a state of irritability and fatigue to avoid accidents and ensure operation safety.
Two, before mechanical work, check whether the moving part is filled with lubricating oil, and then start and check the clutch, brake is normal, and the machine tool empty operation for 1-3 minutes, mechanical failure is prohibited to operate.
Three, when changing the mold, first turn off the power, press movement department stops running, can start to install and debug the mold. After the installation and adjustment, test the flywheel twice by hand to check whether the upper and lower molds are symmetrical and reasonable, whether the screws are firm, and whether the blank holder is in a reasonable position.
Four, must wait for other personnel to all leave the mechanical working area, and take away the work table sundries, can start the power supply to start the machinery.
5. After the machine is started, one person shall transport materials and operate the machine. Other people shall not press the power construction or step on the pedal switch board, let alone put their hands into the mechanical working area or touch the moving part of the machine with their hands. When the machine is working, it is forbidden to stretch the hand into the slider working area, and it is forbidden to take or release the work piece by hand. Standard tools must be used when taking and releasing work parts from the die. If the machine has abnormal sound or malfunction, the power switch should be turned off immediately for inspection.
Six, when off work, should turn off the power, and tidy up the finished products, side materials and sundries on the post, to ensure that the working environment is clean and safe.
The above operating rules must be consciously observed, do not violate the rules of operation, failure, should cooperate with maintenance personnel maintenance, accident immediately cut off the power, keep the site report factory waiting for treatment, all the consequences caused by the violation of operating rules, by the parties to bear all the consequences.
Classification:
Hardware surface processing subdivision can be divided into: hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing and so on
Surface processing of hardware parts:
1, spray painting processing: hardware factory in the production of large hardware products are used spray painting processing, through spray painting processing to avoid rust hardware, such as: daily supplies, electrical shell, crafts, etc.
2, electroplating: electroplating is also the most common metal processing a kind of processing technology, through modern technology on the surface of the hardware electroplating, to ensure that the product for a long time under the use of mildew rust, electroplating processing is common: screws, stamping parts, battery pieces, car parts, small accessories and so on.
3, surface polishing machining, surface polishing processing generally are frequently used in daily necessities, burrs treatment on the surface of a metal products such as: we produce a comb, comb the hardware that is by stamping, stamping out comb edge is very sharp, we'll part by polishing the edges sharp thrown into the smooth face, This will not cause harm to the human body in the process of use.
Turning outer round surface is the basic method of metal processing outer round surface processing, the equipment used is a lathe. Lathes account for about 40% of the total number of machine tools in general machinery factories. Turning is the main method of roughing and semi-finishing the outer surface of various materials, and also the final finishing method of various materials that are not suitable for grinding.
In small batch production of a single piece, turning the outer round surface is generally carried out on ordinary lathes. In mass production, multi-knife semi-automatic lathe or automatic lathe is widely used. Large disk parts should be machined on vertical lathes. Large long shaft parts are machined on heavy horizontal lathes.
The characteristics of turning outer circular surface are:
1, the tool is simple, easy to manufacture, grinding and installation;
2, the cutting process is stable, the cutting force fluctuation is small, is conducive to the use of high cutting speed, improve productivity;
3, the machine has good versatility, it can process the outer circle, end face, inner hole, thread and chamfering in one clamping. The mutual position accuracy of each surface is easy to ensure;
4, suitable for finishing non-ferrous metal parts.
