Product Detail

CNC Multi-Strip Paperboard Slitting & Chamfering Machine for Transformer Oil Duct

Engineered for distribution transformer insulation, this multi-stick paperboard forming machine combines strip slitting and dual-side chamfering (arc edges) into one automated process. It produces 10–20 oil duct sticks per feed with burr-free, smooth surfaces. Delivering 5× productivity and 20% material savings, it features semi-auto dual-shaft feeding, adjustable tool shafts, plate thickness adjustment (3–15mm), and an integrated cooling/dust-removal system with bag filter. Ideal for transformer spacer blocks with straight/swallow-tail slots.

Description

1. Core Features & Advantages

① Slitting & Chamfering Integration

One-time forming of multi-strips (10–20 pcs) with arc chamfers on both sides. Eliminates secondary processing, ensures smooth, burr-free surfaces for superior transformer insulation.

② High Efficiency & Material Savings

At least 5× more efficient than single-strip forming machines, with 20% higher material utilization rate. Discharging speed 5–10 m/min; max 22 strips per discharge.

③ Precision & Flexibility

Handles stick thickness 3–15mm, width 5–70mm, max feeding width 150mm. Each tool shaft adjustable; plate thickness adjustment function for varied insulation board specs.

④ Semi-Automatic & Safe Feeding

Front and rear dual driving shafts enable automatic, smooth feeding. Semi-automatic feeding system with safety dustproof cover ensures operator safety and stable production.

⑤ Cooling & Dust Removal System

Equipped with cooling, dust removal, and bag filter to extend blade life, reduce dust, and maintain workshop cleanliness.

⑥ Transformer-Specific Output

Finished strips used for oil duct, spacer blocks with straight or swallow-tail slots—critical for transformer insulator manufacturing.
