Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically a wire harness pulling and cutting mechanism. Background Technology

[0002] A wire harness is an assembly consisting of copper contact terminals (connectors) crimped to wires and cables, and then covered with an insulator or an outer metal shell. The wire harness is bundled together to form a circuit connection. The wire harness industry chain includes wires and cables, connectors, processing equipment, wire harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments.

[0003] A wire harness cutting machine for wire harness processing, authorized by announcement number CN220144640U, includes a support base, a wire harness flat cutting device, an adjustable wire harness clamping device, a wire harness clamping rotating support plate, and a wire harness clamping rotating rod. The adjustable clamping mechanism positions the wire harness and then evenly lays and clamps it. A translational cutting mechanism is then used for integrated cutting, ensuring the flatness of the cut surface. However, this wire harness cutting machine has a limited straightening length, making it difficult to simultaneously consider the wire harness's extension and prevent damage. Furthermore, the wire harness needs to be cut in equal sections to ensure that the length, resistance, and other electrical parameters of each section are as consistent as possible.

[0004] To address the aforementioned issues, a wire harness pulling and cutting mechanism is proposed. Utility Model Content
