Hydraulic Forming Distribution Box

A Hydraulic Forming Distribution Box is produced by applying controlled hydraulic force to shape sheet metal into electrical enclosures, often integrated into automated roll-forming production lines.

Overview

Hydraulic forming is a sheet metal manufacturing process that converts flat metal sheets into precise shapes using hydraulic pressure. In the context of distribution boxes, this process allows for accurate bending, punching, and forming of steel or stainless steel sheets into enclosures used for electrical distribution systems. The method ensures permanent deformation without cracking, making it suitable for high-quality, durable boxes.

Production Process

Modern hydraulic forming distribution box production typically involves a fully automated line: Uncoiling and Straightening: Steel coils (cold-rolled or galvanized) are manually loaded onto an uncoiler and straightened to remove tension and curvature.

Hydraulic Pre-

Punching: The sheet passes through a hydraulic device for pre-punching and notching, preparing it for forming. Roll Forming: The sheet is guided into a roll forming machine where 16 sets of rollers progressively shape the metal into the box profile. Bending and Cutting: Hydraulic bending devices precisely bend the sheet into the final box shape, and cutting mechanisms trim it to size.

Manual Packing: Finished boxes are removed and packed for shipment, with production rates typically 2-3 units per minute, depending on specifications.

Technical Specifications
