Q:After the powder metallurgy parts are machined, how to prevent rust?
2, improve the way: Immersion replacement type rust preventive oil, in fact, the base oil or kerosene based, but added a corrosion inhibitor, can improve rust prevention period, about 6-12 months.
Q:What is the definition of machining process specification?
For example, a common part of the processing process is rough - finishing - assembly - Inspection - packaging, is a general process of processing
Q:The true size of a mechanical part is based on what is on the drawing
The size of the machine parts shall be in accordance with the size of the drawing as specified on the drawings, and be sure to differ from the marked sizes on the package, especially the irregular parts.
Q:What are the main parts of small vacuum machines?
On the vacuum chamber, opening displacement and balancing deviceThe commonly used vacuum machine has a single room and double room two, single room for tipping, two stents in the upper and lower vacuum chamber with a middle rear, wearing a double torsion spring axis by double torsion spring force balance, the opening angle of 45-75 degrees ranging. Double chamber for reciprocating, vacuum chamber is divided into two studios, vacuum chamber comprises four connecting rod support about displacement, the four connecting rods is fixed on the two axis, the long axis of a spring fork, two tension springs located in the lower frame, the upper part of the positioning in the spring fork, to balance the operation of gravity, two axis by two sets of bearing positioning, four upper connecting rods with miniature bearings, so the displacement is very easy, starting with vacuum pressure, back after gas can automatically open. The four connecting rods on the support displacement of the vacuum chamber, before and after each axis on the two, must be kept parallel to about two sets of connecting rods must remain relatively parallel, to ensure that the vacuum chamber remain parallel in about any position under the same vacuum chamber or cause the upper and lower vacuum chamber can't keep parallel, then the operation pressure increased significantly, even can not establish normal vacuum. Small treasure vacuum machine
Q:What should we pay attention to when choosing the quantitative packing machine parts?
You look for it. If not, try another one. If you don't understand, you can chase me. I'll explain it to you slowly.
Q:Gearbox mechanical parts, mechanical and electrical products?
It's definitely not standard. It means structure, size and painting,
Q:As a mechanical component inspector, how do you improve the quality of your product?
The parts pass through your hand, reject the unqualified, pass the qualified product, and improve the quality of the product naturallyIt is very simple, but the actual work, the traditional code of conduct reason, you feel it is difficult to do, so you have to make the spirit of seeking principle, adhere to in the end.
Q:Single vacuum packaging machine accessories, vacuum schedule, where to sell?
Vacuum packaging machine parts, it is best to buy from the original manufacturers, because many vacuum packaging machine, although the main technology is similar, but there will be many differences in detail, size will vary
Q:The standard problem of parts in mechanical drawing
General standard length do you think if you are processing personnel or material you must know it is you can also let people go well, a principle to remember is to consider on you do not affect the case of others. You can mark the height of the label you want as the associated size
Q:Functional configuration of plastic processing machinery
In the application, China injection molding machines in general, general plastic products such as toys, stationery, daily necessities, furniture, decoration materials occupy the largest share of the market.Secondly, the injection molding machine mainly used for large household appliances, such as refrigerators, color TV, washing machine, air conditioner, computer shell production, the market using the above Chinese total engineering plastic injection molding machine 40%, domestic high share in this market.Another important field of injection molding machine applications is the production of packaging products, mainly used for PET bottles, plastic bottles, caps and other products. The PET preform injection molding machine market mainly imported equipment control.Optical disk (CD), digital image compact disk (DVD), magnetic disk (MD) and micro optical disk (MDS), as the recording medium, are increasing rapidly all over the world. China has developed CD-ROM injection molding machine, but has not yet been widely used.Some special injection molding machines, such as ceramic injection molding machines for producing fine ceramic components and magnetic injection molding machines for producing NdFeB electronic components, have not been paid much attention by machinery manufacturers due to their low consumption. But with the further subdivision of the market, it is very important to develop the relevant specific models.Similarly, the special injection molding machine for thin-wall or special engineering plastic products is still blank in China, mainly occupied by imported equipment. With the mobile phone shell as the representative of the thin-walled product demand, the development potential of the huge market.
