Fin punching machine P14×10

The upper and lower die tables maintain a levelness tolerance of ≤0.03mm, and the center-spindle force transmission layout minimizes lateral deflection during each stroke. This delivers fin tooth height accuracy within ±0.01mm — critical for heat exchangers where uniform fin geometry directly affects heat transfer efficiency and refrigerant-side pressure drop.

A 4/5 kW motor with variable-frequency control provides continuously adjustable stroke rates from 35 to 120 times per minute. Operators can fine-tune speed for thin aluminum stock or thicker copper strip without swapping gears, reducing downtime and eliminating the wear associated with mechanical transmission switching.

The production line includes a purpose-built decoiler (1,000 kg capacity, 0.75 kW motor) and a servo-driven cutter that handles widths from 10 to 450mm. Together, they enable coil-to-finished-fin production in a single pass, removing the need for separate upstream slitting or downstream trimming stations.

An automatic lubrication system supplies oil to all critical wear surfaces on a timed cycle, reducing friction-related degradation. The compact, structurally optimized frame keeps the total part count low, which simplifies troubleshooting and lowers spare-parts inventory costs. Total machine weight of 1,500/1,800 kg provides sufficient rigidity for the 6,000 kg strike force without oversized foundations.

The Mitsubishi PLC and Delta touchscreen interface let operators store fin recipes, monitor cycle counts, and adjust parameters without manual calculations. A dedicated mold height adjustment mechanism allows a single technician to change and align dies for different fin profiles, keeping changeover times short in mixed-production environments.
