Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a cutting die for automobile wiring harnesses. Background Art

[0002] A wiring harness is a component that is formed by crimping a contact terminal connector made of copper material with a wire and cable, and then plasticizing an insulator or adding a metal shell on the outside to form a connecting circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. When producing automotive wiring harnesses, they need to be cut. Since the existing technology produces a large error in cutting length, it does not meet the wiring harness cutting standard. Therefore, patent CN217451922U proposes "a cutting die for automotive wiring harnesses", which uses active rollers and driven rollers to transport the wiring harness, and then starts the cylinder to drive the blade downward through the cylinder until the wiring harness is cut off, solving the problem that the existing cutting die operation process is extremely cumbersome. Some operators even directly cut the wiring harness with scissors, resulting in a large error in cutting length and failing to meet the wiring harness cutting standard.

[0003] However, in this solution, since the positions of the active roller and the driven roller cannot be adjusted, the distance between the two rollers cannot be adjusted, resulting in the equipment being unable to be used to transport wire harnesses of different specifications, reducing the applicability of the equipment. Therefore, a cutting mold for automotive wire harnesses is proposed. Utility Model Content
