- Q: Why the screw thread more closely, spin into the more effort?
- This is due to the spiral angle of the thread becomes smaller, the pitch of the thread, the lead becomes smaller.
- Q: The idiom of the screw
- Lei Feng: I would like to always make a screw, a person's role, for the cause of the revolution, as a machine on a screw machine as a result of the many screws and fixed, only to become a solid whole, can Run freely, play its great ability to work. Although the screw is small, its role is not underestimated. I would like to make a screw hello forever. Screw to regular maintenance and cleaning, it will not rust. People's thinking is the case, to always check will not go wrong
- Q: The Symbolic Meaning of Screw
- The "crazy screw" is in the life and employment under the dual pressure, long-term super-strength, over time limit of labor, the spirit of life, , Constantly challenge the physical and psychological limits of a group of people, they bear the hard work day and night, physically and mentally tired tired, gather more away from the family, is the new era of labor and employment environment of a deformed landscape.
- Q: Screw hole slip wire how to do?
- Can be in the original screw hole at the larger screw hole to cover the original screw hole, the most good new hole diameter is greater than the original hole diameter; 2. If the original thread hole has no space, then just change to other places to re- drilling
- Q: What is the difference between Chinese-made screws and US screws?
- Formal manufacturers of screws from the size of the model is no difference (except small factories or workshops), the difference is mainly from the manufacture of screws and materials used in the surface of the treatment process only. Say even the Chinese exports of screws, in terms of manufacturing is also in accordance with foreign standards or contract requirements (such as the use of foreign customers specific raw materials or technology), the cost is relatively high, not the domestic market sales. Reference it.
- Q: Was rusty rust, the screwdriver are turning how to do, is a very important thing
- Drop a few drops of oil or gently knock around a few times, to the rusty screw drops (to bubble better) gasoline or kerosene, washing the use of oxalic acid also
- Q: Also known as screw nails, I want to nail on the board, but there is no way to nail into the hard, how nail?
- 1, first clear the broken screw on the surface of the sludge with the center of the center of the gun will be killed by the center of the drill and then drill with a diameter of 6-8 mm drill bit in the center of the drill hole drilling, pay attention to the hole must drill through. After the hole is drilled, remove the small drill bit and replace the drill with a diameter of 16 mm. Continue to expand the hole of the bolt and drill it through. 2, take the diameter of 3.2 mm below the use of small and medium current in the broken bolt in the drilling from the inside to the outside of the surfacing welding site to take the beginning of the bolt half of the length of the bolt can not start too long So as to avoid breaking the outer wall of the broken bolt. Surfacing to the upper end of the broken bolt and then continue to pile out a diameter of 14-16 mm high 8-10 mm cylinder. 3, after welding with a hand hammer hammer its end point so that the broken bolt along its axial vibration.As the previous arc heat and subsequent cooling coupled with the vibration at this time will break the bolt and the body of the thread Between the resulting loosening. 4, carefully observed when you find a trace of rust after the break from the fracture when you can take the M18 nuts in the surfacing stigma and the two welding. 5, after welding with a cool hot plum wrench on the nut around the back and forth twist can also be back and forth twist side with a small hammer hammer the end of the nut so that you can remove the bolt off. 6, remove the broken bolt with the appropriate tap to the fabric within the rack to remove the hole to remove the rust and debris.
- Q: What is a self-tapping nail? Is it used? What are the characteristics of the shape? What is the difference with ordinary screws?
- Self-tapping screw head shape with round head, flat head, semi-countersunk head and countersunk head and so on. Materials generally carburized steel, heat treatment after the surface hardness of not less than 45HRC.
- Q: Inside the hexagonal screws, rather not down, it may be too much screw on the screw too tight has been bad 3 screwdriver screw is too small also one-half of rice grain please help think about ways
- T-shaped irons and screws, you can twist it off
- Q: How is the screw produced
- Annealing: the wire heated to the appropriate temperature, to maintain a certain time, and then slowly cooling to adjust the crystal structure, reduce hardness, improve the room temperature processing. Pickling: Remove the oxide film on the surface of the wire and form a layer of phosphate film on the metal surface to reduce the wire drawing and cold pier or forming process. To the required diameter. Practical for some products can be divided into coarse pumping (shelling) and fine pumping two stages. Molding: The wire is forged by cold forging (or hot forging) to achieve the shape and length (or thickness) of the finished product. The finished semi - finished product is rolled or tapped to achieve the desired thread. Practical for the bolt (screw) known as the rolling teeth, teeth known as the rolling teeth, nuts called tapping. Heat treatment: according to the object and the purpose of different different heat treatment can be used. Quenched and tempered steel: quenched high temperature tempering (500-650 ℃) spring steel: quenched after tempering temperature (420-520 ℃) ??carburizing steel: carburizing after quenching and then low temperature tempering (150-250 ℃) low carbon and In the carbon (alloy) steel quenched into martensite, with the tempered temperature rise, the general rule is the strength decreased, while the plasticity, toughness rise. Surface treatment: surface treatment that is through a certain method in the workpiece surface coating process, the purpose is to give the product surface appearance, anti-corrosion effect.
