Small Adjustment Straight Machine Distribution Box

A Small Adjustment Straight Machine Distribution Box is an electrical enclosure produced using adjustable roll forming and bending machines, designed for flexible, decentralized power or signal distribution.

Overview

A distribution box is an enclosure that houses electrical components for power, signal, or data distribution. These boxes are widely used in buildings, industrial plants, and smart building automation systems, providing a safe and organized way to manage electrical circuits while allowing for modular and decentralized installation .

Manufacturing Process

The production of these boxes typically involves a straight machine or roll forming line with adjustable parameters:

  • Uncoiler and Straightening: The metal strip (cold-rolled or galvanized steel) is placed on an uncoiler and straightened to remove tension and curvature .
  • Servo Feeding and Hydraulic Punching: The strip is fed into a hydraulic device for pre-punching holes for cables, hinges, or ventilation .
  • Roll Forming and Bending: The strip passes through a roll forming machine and bending device, shaping it into the final box dimensions. The machine allows height, width, and depth adjustments to accommodate different box sizes .
  • Cutting and Packing: The formed boxes are cut to length and manually packed. Production speed is typically 2–3 enclosures per minute, depending on specifications .

Features and Adjustability

  • Size Flexibility: Height adjustable from 300–1200 mm, depth 150–400 mm, and width adjustable on some models .
  • Hole Customization: Cable holes, door hinge holes, and other cutouts can be set via PLC control for precise placement .
  • Material Compatibility: Suitable for cold-rolled steel, galvanized steel, and stainless steel with tensile strength up to 780 MPa .
  • Robust Construction: Machines use high-quality bearings and welded steel frames for stability and consistent forming .

Applications

  • Decentralized Power Distribution: Ideal for placing electrical components close to the load, reducing wiring complexity .
  • Industrial and Smart Buildings: Supports modular installation, pluggable connections, and integration with automation systems .
  • Harsh Environments: Many distribution boxes are designed to withstand moisture and dust, with protection ratings up to IP67 .

Summary

A Small Adjustment Straight Machine Distribution Box combines the flexibility of adjustable roll forming machinery with the functionality of modular electrical enclosures. It allows manufacturers to produce boxes of varying sizes efficiently while meeting the requirements of decentralized power and signal distribution in industrial, commercial, and smart building applications .
