In infrastructure sectors such as power engineering, intelligent building systems, rail transit, and data centers, cable trays serve as essential components for ensuring orderly cable installation, safety protection, and convenient operation and maintenance. With the scaling up and standardization of the infrastructure industry, traditional production methods involving manual welding and segmented bending can no longer meet the demands for high precision, efficiency, and cost-effectiveness. As specialized automated cold-bending equipment, cable tray forming machines enable one-step continuous processing of metal coils, making them the core intelligent solution for manufacturers to achieve large-scale production and enhance product quality, and are widely used in the standardized manufacturing of various metal cable trays.

Core Definitions and Operating Principles of the Device

The cable tray forming machine, also known as the cable tray rolling forming machine, is an integrated automated production line designed based on cold bending and progressive deformation technology. It eliminates the need for high-temperature processing; by applying sequential pressure from multiple sets of precision rollers, it continuously processes metal sheets such as galvanized steel strips, stainless steel strips, and aluminum alloy strips into various standard cable tray profiles—including trough-type, ladder-type, and tray-type configurations—without requiring any secondary welding or shaping steps, producing finished components in a single operation.

Its core working principle is metal progressive plastic deformation: a flat metal coil is fed into the equipment via a feeding system and passes sequentially through multiple sets of orderly arranged forming rollers. Each set of rollers applies a preset bending angle corresponding to the cross-sectional dimensions of the cable tray, gradually altering the sheet’s shape to prevent deformation and cracking caused by single-bending operations. Through precise mechanical configuration and a servo control system, the curvature, side length, and hole diameter height of each cable tray segment are maintained consistently. After forming, the sheets undergo precision cutting and automatic material collection, enabling fully automated production that effectively preserves the original structural strength of the metal material while enhancing product durability.

The overall structure of the device and its core components

The fully automated cable tray forming machine features a modular integrated structure, with each unit working in synergy to form a complete automated production chain. Its core components include six major systems: feeding, leveling, punching, forming, cutting, and control, offering a compact design with strong interconnectivity.

Decoiler andfeeding unit

As the feeding end of the production line, it primarily handles metal steel coils, delivering raw materials at a constant speed via an automatic unwinding mechanism. Capable of accommodating coils with varying weights and widths, it ensures stable feeding without deviation, provides reliable material supply for continuous production, and effectively eliminates the delays and misalignments associated with manual feeding.

Leveling Unit

Equipped with multiple sets of high-precision leveling rollers, this system corrects issues such as warping, wrinkling, and deformation that occur during sheet material transportation and storage, restoring curved metal sheets to a flat surface and completely eliminating the impact of material deformation on subsequent forming accuracy. It serves as the critical component ensuring cable tray flatness.

Servo punching unit

Using servo-driven precision feeding combined with specialized punching dies, the system can perform accurate punching of connection and mounting holes online according to cable tray installation standards. The hole spacing and diameter can be freely adjusted via the control system to meet various cable tray specifications. Compared to manual drilling, this method offers higher accuracy and greater efficiency while effectively preventing issues such as hole misalignment and excessive burr formation.

Rolling forming

As the core working unit of the equipment, it is equipped with 12–20 sets of high-precision forming roller stations featuring a modular adjustable roller design. Without requiring roller replacement, various types of cable trays with base widths ranging from 100 mm to 860 mm and groove depths from 50 mm to 200 mm can be produced simply by adjusting parameters, meeting the production requirements of most engineering applications with exceptional versatility.

Fixed-length Cutting Unit

Equipped with a hydraulic flying shear cutting mechanism, it supports online dynamic fixed-length cutting and allows presetting of cable tray lengths according to production requirements. The cutting process requires no machine shutdown, enabling continuous production. The cut edges are smooth without burrs or deformation, with dimensional errors strictly controlled within minimal limits, ensuring standardized dimensions for each finished cable tray.

Intelligent Electronic Control System

Centered around a PLC (Programmable Logic Controller) and equipped with a touch-sensitive control panel, the system integrates comprehensive functions including speed regulation, specification switching, fault alarms, and counting statistics. Operators can directly configure production parameters on the panel, enabling the equipment to automatically complete the entire operational process. Additionally, it features overload protection and automatic deviation correction capabilities, significantly reducing equipment failure rates.

Standardized Production Process Procedures

The cable tray forming machine employs an integrated continuous production process with fully automated closed-loop operation, requiring no manual intervention. The standard production procedure is clear and sequential: coil unwinding → plate leveling → servo-driven feeding → online punching → multi-roll rolling forming → precise length-cutting → automatic material collection and stacking. The entire process is completed in a single step, eliminating intermediate transfer or secondary processing steps.

Based on different production modes, the equipment is categorized into low-speed punching mode and high-speed forming mode: the precision production with punching capability operates at 2.5–5 meters per minute, suitable for manufacturing high-precision finished cable trays with pre-defined hole positions; the non-punching pure forming high-speed mode achieves a conventional production speed of 12 meters per minute, while advanced models can reach up to 18–20 meters per minute for high-volume production, meeting both small-to-medium batch customization requirements and large-scale supply needs for major engineering projects.
