Product Detail

Transformer Insulation Paperboard Compacting & De-burring Machine (for Cushion Blocks, 50T Pressure)

YIBO Paperboard Compacting and De-burring Machine is engineered for precision processing of transformer insulation strip boards (cushion blocks). It integrates high-pressure densification (max 50T rolling pressure, 8~10% compression ratio) with synchronized chamfering and de-burring (6000r/min milling, custom R-angles). Handles thickness 1.5~30mm, width 7~100mm, length ≥500mm, at variable feeding speed 5~20m/min (inverter stepless). The synchronized compacting-deburring process ensures smooth edges, uniform density, and ready-to-use cushion strips. Machine allows flexible separate configuration for compacting or deburring alone. Backed by YIBO’s 23+ years expertise in transformer insulation machinery.

Description

1. Core Features & Advantages

① Dual-Action Densification & Chamfering

Densifies strip insulation board (compression ratio 8~10%, max 50T pressure) while simultaneously milling/chamfering edges (R-angle per customer designation) to remove burrs, ensuring clean, dense cushion blocks.

② Wide Thickness & Width Adaptability

Processes paperboard thickness 1.5~30mm, width 7~100mm, length ≥500mm. Ideal for diverse transformer cushion strip specifications.

③ Synchronized Stepless Feeding & Milling

Feeding speed 5~20m/min with inverter stepless regulation; compacting and de-burring operate in sync. Milling spindle speed 6000r/min for high-efficiency edge finishing.

④ High-Pressure Rolling System

Maximum rolling pressure 50T delivers consistent board densification. Enhances mechanical strength and dimensional stability of insulation strips.

⑤ Flexible Process Configuration

Can be configured as combined compacting + deburring unit, or separated for individual compacting or deburring operations, adapting to varied production needs.

⑥ Precision & Automation

Equipped with independent control panel for seamless operation. High-speed milling (6000r/min) with dust extraction (visible hose) maintains clean workshop. Custom R-angle tooling available.
