[0002] Spring steel wire is a kind of steel wire used to make springs or steel wire profiles. According to the different uses of springs, there are many types of spring steel wire required to make springs, such as spring steel wire for mattress springs with lower requirements, spring steel wire for shock absorbers, spring steel wire for suspension springs, spring steel wire for engine valves and spring steel wire for camera shutters, etc. During the spring steel wire processing, the spring steel wire is placed in a roll on a cylinder, and then one end of the spring steel wire is led to the cylinder by the traction equipment of the machine tool for winding.
