একটি electric cabinet frame machine is an important piece of equipment used to manufacture metal cabinet enclosures and racks for electronic controls, switchgears, distribution boards, and automation systems. This comprehensive guide provides key details about electric cabinet frame machines.
Overview
Electric cabinet frame machines, also known as roll formers or bending machines, automate the process of shaping metal sheets into custom cabinet frames and enclosures through a series of bending, punching, cutting, and rolling operations.
They offer an efficient alternative to manual metal fabrication, enabling high productivity and consistency in producing cabinets of various sizes with different structural designs to meet safety and electrical standards. Modern electric frame machines include programmable controls and touchscreen interfaces for flexible and precise fabrication.
Main Components
The major components of an electric cabinet frame machine include:
- Feeding mechanism – Auto-feeds raw metal coil/sheets
- Roll forming stations – Forms bends through an arrangement of rollers
- পাঞ্চিং ইউনিট – Punches holes for rivets and cables
- Shearing blade – Trims sheets to required cabinet size
- Controller – Controls machine parameters and production flow
Working Process
The typical working process on an electric cabinet frame machine involves:
- Loading raw metal sheet or coil
- Feeding material through sets of rollers and bend stations
- Forming structural bends and rolls as required
- Punching/cutting electrical cabling holes
- Shearing final enclosure frame to dimensions
- Unloading finished cabinet carcass

Working Principle
The working principle involves feeding a metal sheet or coil through various fabrication stations to shape it into a finished cabinet frame. The material gets formed into custom bends and profiles through an arrangement of rollers, while holes get punched by pneumatic rams. Finally, a shearing blade cuts the frame to the exact size required.
Industrial Applications
Electric cabinet frame machines enable efficient mass production of enclosures for:
- Power distribution boards
- Motor control centers
- Switchgears and control panels
- Operator interfaces and consoles
- Battery racks and chargers
- Instrumentation cubicles
- Automation system cabinets
