Technical Field
[0001] This utility model relates to the field of spring steel wire processing technology, specifically a manual bending device for spring steel wire. Background Technology
[0002] Spring steel wire is a type of steel wire used to make springs or wire-shaped components. Depending on the application of the spring, there are various types of spring steel wire required for making 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. Spring steel wire can also be classified according to the manufacturing process, such as raw drawn spring steel wire, lead-quenched spring steel wire, galvanized spring steel wire, and oil-quenched spring steel wire. Spring steel wire needs to be wound around a bent rod one coil at a time to form the basic shape of a spring.
[0003] Existing bending equipment produces springs of different sizes, requiring the replacement of bending rods of different corresponding sizes. However, disassembling the bending rod is inconvenient and time-consuming. The wire end is not fixed on the bending rod and is prone to slipping, which is not conducive to the winding and bending of the wire. Therefore, there is an urgent need for a spring wire bending method. Utility Model Content
