Q:What is the meaning of the 8.8 on the screw
The so-called 8.8 grade refers to the bolt shear stress rating of 8.8GPa
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:What is the invention of the screw?
Should be the 18th century Mozzley in London invented all-metal precision screw lathe. The following year, Wilkinson made a nut and bolt making machine in the United States. Both machines can produce universal nuts and bolts. Nuts and bolts can be connected together metal parts, so to the 19th century, the manufacture of machinery to build houses of wood, has been replaced by metal.
Q:Why a screwdriver can suck the screw
Because the top of the screwdriver with magnetic junior high school there
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 screws are in the metal or non-metallic materials in the pre-drilling in the self-drilling with a threaded thread with a threaded fastener. Self-tapping screws with high tension, single, unilateral combination of features. Self-tapping screws are used for connection between thin metal plates (steel plates, saw boards, etc.). When connecting, first thread the bottom of the connector, and then screw the tapping screw into the threaded bottom hole of the connected part. As the tapping screw thread surface has a high hardness (≥ 45HRC), can be connected to the threaded bottom hole in the internal thread, thus forming a connection.
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:Engineering argument, usually referred to as the M3 screw, M refers to what is the meaning? The Please instruct the engineering staff.
M: ordinary thread;: screw that thread diameter (ie, the top of the thread) is 3mm, nuts that thread diameter
Q:What is a screw? What is a nail? What is the concept? What is the difference!
The screw is a threaded stud that is fastened to two objects, with a threaded screw in the column, usually screwed and nailed. Machine nail is used for mechanical attack on the use of a good thread, or with nuts used to fasten the product, according to the material requirements have a certain force. The range of screws is wide, the nail is just one of the screws inside.
Q:Why are the screws of the screw?
Fine thread thread pitch is small, the angle is small, self-locking is better, high strength, because the teeth are not wearable, easy to slip. Fine thread is often used in fine parts, thin-walled pipe fittings or by the impact, vibration and variable load connection, can also be used as fine-tuning mechanism for adjusting the thread.
Q:How does the screw rust die?
1 shock: for the rusty screws, do not use a wrench hard to prevent the screw screw six edges and corners, screw off the screw or wrench bad wrench. At this point, you can use the hammer gently shake the handle of the wrench, the general rust-proof screws can be twisted under the vibration. 2 knock: with the edge of the top hammer, knocking the corrosion of the nut, it is easy to loose nut. For example, the bike's feet at both ends of the fixed bolt nut, according to the foot pedal thickness, metal structure, grasp the size of the force hit the nut. Cast iron at the nut can be slightly larger force, plastic to gently beat. If you still can not, then use the hammer along the direction of the circle beat the nut, you can easily remove the nut.
Our high-quality products are widely used for precision machinery, fitness equipment, printing machinery, packing machinery, medical and pabular machinery, woodworking machinery, automatic textile production lines, and other machinery.We zealously welcome all customers to give your guidance and discuss business.
