- 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.
