Description

Technical Field

[0001] The utility model relates to the technical field of wire harness cutting, in particular to a wire cutting machine for electrical cabinet wire harnesses. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials to protect the normal operation of components. The components inside the cabinet need to be connected by wire harnesses. Different components use wire harnesses of different lengths. When connecting the components inside the electrical cabinet, the wire and the components are generally connected by manually cutting the wire harness.

[0003] At present, the method of manually cutting wire harnesses has low efficiency. And when encountering wire harnesses with a larger diameter, manual cutting will cause the cut of the wire harness to be uneven, which is not easy to fit with the docking part during subsequent docking. At the same time, the uneven cut will cause the wire and the docking part to easily generate electric arcs, burning and damaging the docking part. Summary of the Utility Model

A cutting knife is slidably arranged between the inner walls of the protective sleeve. A buffer groove is provided between the inner walls of the fixed sleeve, and the buffer groove is located directly below the protective sleeve. A four-corner ring is arranged on the outer surface of the fixed sleeve near one side edge.

[0006] Optionally, the cutting part at the bottom of the cutting knife extends into the buffer groove. Two connecting rods are fixed to the top of the cutting knife, and the tops of the two connecting rods are both fixed to the bottom of the pressing plate.

[0007] Optionally, a plurality of through openings are equidistantly arranged along the circumferential direction at one end of the fixed sleeve, and a turntable is rotatably connected to one end of the fixed sleeve.

[0008] Optionally, telescopic rods are slidably connected between the inner walls of the plurality of through openings, and one ends of the plurality of telescopic rods respectively extend into the fixed sleeve.
