Description

Technical Field

[0001] The present application relates to the technical field of cable processing equipment, and in particular to an automatic cutting and punching machine for automotive flat cables. Background Art

[0002] Flat cable is a current conducting wire with a rated voltage below 450V and a flat waist-shaped cross-section. Its flat structure has good flexibility and bending resistance, and is particularly suitable for occasions with frequent bending, such as mobile electrical equipment such as automobiles. Due to its good mechanical and electrical properties, flat cables are widely used in power generation, metallurgy, chemical industry, port transportation and other industries.

[0003] The common production process of flat cables includes the processing steps of punching and cutting at specific locations of the cable. At present, the industry usually uses integrated punching and cutting equipment to process cables. This equipment is generally equipped with receiving and unloading rollers, and punching modules and cutting modules are respectively provided to punch and cut the cables at specific locations. During the production process, it was found that since the punching module and the cutting module can only process a certain part of the cable after one feeding action, the overall efficiency of the cable production and processing is limited by the number of punching modules and cutting modules. The common integrated punching and cutting equipment with a single punching and cutting module has the defect of insufficient processing efficiency when dealing with large-scale flat cables with multi-hole processing needs.

[0004] With regard to the above-mentioned related technologies, it can be known that the existing flat cable punching and cutting integrated equipment has the technical defect that the processing efficiency is restricted by the number of modules, and the problem of insufficient processing efficiency will occur in certain processing scenarios. Summary of the invention

[0007] By adopting the above technical scheme, the feeding mechanism can feed the processing mechanism to realize continuous processing, and the supporting mechanism can tension the multi-layer flat cable in a reciprocating and overlapping manner, so that the processing mechanism can complete the punching operation at multiple positions on the flat cable after one punching stroke. Compared with the original processing structure, the processing mechanism of the present application cooperates with the supporting mechanism to significantly improve the overall production efficiency of the flat cable. The sliding connection structure between the guide rail and the support arm can not only be used to adjust the tensioning force, but also can adjust the punching position spacing, which enables the present application to have a wider range of application scenarios.
