Description

Technical Field

[0001] The utility model relates to a wire guide mechanism of a spring machine. Background Art

[0002] Spring machines refer to mechanical equipment for producing springs. According to their functional characteristics, they are divided into compression spring machines, extension spring machines, universal machines, disc machines and special spring machines. Regardless of the type of spring, they all have a lead-in mechanism for introducing the wire into the forming area and a forming mechanism for processing the wire to form it.

[0003] The wire guide mechanism in the prior art can only convey a certain type of steel wire. When changing to other sizes of steel wire, the wire guide mechanism needs to be replaced, which is less practical. Utility Model Content
