Description

Technical Field

[0001] The utility model relates to the technical field of clip spring cutting, in particular to a clip spring cutting device. Background Art

[0002] The spring coiling machine is mainly used for mechanical equipment to produce springs, tension springs and retaining springs. The existing spring coiling machine is provided with a feeding mechanism for conveying metal wire. When the spring coiling machine produces retaining springs, the metal wire extends out of the discharge port through the feeding mechanism, and then the guide block abuts against the metal wire to guide the metal wire, so that the metal wire is deformed into an arc shape. When the metal wire is shaped into a nearly circular shape, the cutter is attached to the discharge port to cut the metal wire, and the retaining spring production is completed.

[0003] The blade of general cutting equipment will become blunt after long-term use, so in the subsequent cutting of retaining springs, it may not be cut continuously. In addition, after the cutting equipment cuts the metal wire, the metal wire will leave deformation marks and burrs at the incision. These deformation marks and burrs are relatively sharp and may leave scratches on the surface of the guide block. The surface of the guide block needs to be polished before the retaining spring can be produced, thereby delaying production efficiency.

[0004] For this purpose, we propose a circlip cutting device. Utility Model Content

[0005] The main purpose of the utility model is to provide a spring clip cutting device. When the cutting edge of the cutting blade becomes blunt or worn, the cutting blade can be replaced in time, and the replacement is convenient and quick.
