Q:What is the principle of screw
A simple mechanical one that can be used to overcome the difficulty of vertically lifting heavy objects. Distance ratio and force ratio are dependent on the inclination. Such as friction is very small, you can achieve very high efficiency
Q:Who knows who invented the screw?
The spirits were invented more than 2,000 years ago, but less than 500 years for fixing things. The first person who describes the spiral is the Greek scientist Archimedes (about 287 BC - 212 BC) The Archimedes spiral is a huge spiral in a wooden cylinder used to The water is raised from one level to another, and the fields are irrigated. Its true inventor may not be Archimedes himself. Maybe he just described something that already existed. Perhaps it was the ancient Egyptian craftsmen who had designed it to use the irrigation on both sides of the river. Archimedes spiral in the ancient society are used to raise water, no one considered to change it into a fixed piece. Archimedes spirals are widely used for water lifting. For example, the Romans used it to drain the mine. In the Middle Ages, carpenters used wooden nails or metal nails to connect furniture and wooden structures. In the 16th century, nail workers began to produce spiral nails, these nails can be more firmly connected things. It was a small step from this nail to the screw. At the end of the eighteenth century, screws were quite popular as fixed parts, because at that time a cheap production method had been found. Screwdriver (chisel) appeared in London around 1780 years. The carpenter found that screwing the screw with a screwdriver was better than a hammer and could fix something better, especially when a fine screw was encountered.
Q:The screw is too tight not how to do it
First engage in a rust or diesel under the bubble. Then T-type wrench twist. (Own do)
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.
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:What is the meaning of the screw and the 4 and 8?
Strength grade 4.8, nominal tensile strength of 400MPA products, yield strength 320 (nominal 80%). For details, please refer to GB3098.1 or ISO898-1. There are all indicators
Q:What is the difference between Chinese-made screws and US screws?
China-made screws are metric, American screws are American Standard or British
Q:How is the screw nailed to the wall
Use a hammer to make a hole in the wall, and then plug a plastic expansion tube, the last screw.
Q:This screw ye use, and how to use next to the cover
With the use of electric drill, with the corresponding screw bit on the wall where the need to make a hole, talk about the plastic protrusion into the hole into the hole, then the screw on the.
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.
