I. Equipment Introduction
The trough-type cable tray cold roll forming machine is an automated system specifically designed to manufacture trough-type cable trays (U-shaped trays with covers). Utilizing a continuous cold roll forming process, the equipment integrates uncoiling, leveling, punching, forming, and cutting into a single, streamlined operation, directly producing finished trough-type cable trays.
Trough-type cable trays are fully enclosed systems characterized by excellent shielding capabilities, resistance to dust and interference, and superior heat dissipation; they are the most widely used type of cable tray for indoor cable routing.
The process flow is as follows: Uncoiling and leveling → Servo feeding and punching → Conveying platform → Guide feeding → Roll forming → Discharge. The entire line features fully automatic PLC control and is equipped with a modular, adjustable forming unit; a single set of rollers accommodates multiple specifications, with width and height adjustments performed automatically by motors, enabling rapid product changeovers via touchscreen parameter input.
The equipment is compatible with various materials, including galvanized steel strip, cold-rolled sheet, and hot-rolled sheet. It handles strip widths ranging from 60 to 950 mm and thicknesses from 0.6 to 2.5 mm, meeting the production requirements for a wide range of trough-type cable tray specifications.
The production line supports both automatic and manual operation modes, allowing for either synchronized (linked) or segmented operation, ensuring flexible and convenient handling.
II. Core Advantages and Selling Points
1. Integrated Uncoiling and Leveling; Space-Saving
The uncoiling and leveling processes are integrated into a compact, well-organized design. Compared to traditional separate layouts, this significantly reduces the factory floor space required. A 7-roller leveler ensures precision leveling, effectively eliminating internal material stress and guaranteeing accuracy in subsequent forming stages.
2. Servo Feeding & Punching; High Speed and Efficiency
A high-precision servo system ensures accurate feeding and positioning, working in tandem with a punch press to create bottom stiffening ribs and various connection holes for the trough-type cable trays. Punching speeds reach 60–90 strokes per minute, offering a significant efficiency boost over traditional methods. Precise servo positioning minimizes waste, effectively lowering material costs.
3. Conveying Platform; No Civil Works Required
Equipped with a dedicated conveying platform, the system eliminates the need for on-site material storage pits, drastically saving on civil engineering investment and construction time. This reduces infrastructure costs and shortens the time to production, making it ideal for upgrading existing facilities.
4. Guided Feeding; Adaptable to Multiple Specifications
An automatic guiding device corrects material alignment, ensuring the steel strip enters the main forming unit smoothly. It accommodates varying strip widths, allowing for specification changes without tedious manual adjustments. Paired with a modular, adjustable forming unit, a single set of rollers can produce a wide range of trough-type cable tray specifications.
5. Roll Forming; Automatic Profile Switching
The main forming unit features a modular, adjustable structure; specification changes are handled automatically by motors that adjust the machine's opening width and roller settings. Operators simply input parameters via a touchscreen to switch profiles, eliminating the need to replace entire tool sets. This significantly lowers skill requirements and saves time and effort, making it perfect for rapid production switching across diverse product types and specifications.
6. Trough Structure; Superior Protection Performance
The produced trough-type cable trays feature a fully enclosed structure with excellent shielding capabilities, effectively preventing electromagnetic interference. Their outstanding dust-proof and anti-interference properties make them particularly suitable for indoor cabling environments requiring high levels of protection. Trough-type cable trays offer superior dust resistance, interference resistance, and shielding performance compared to tray-type or ladder-type versions; they effectively protect cables from external environmental factors, thereby extending their service life.
7. Intelligent control and ease of operation
Features fully automatic PLC control and a touchscreen HMI for intuitive, convenient parameter setting. Equipped with multiple safety protection devices to ensure operator safety. Includes automatic fault diagnosis and alarm functions for rapid troubleshooting and maintenance. The entire production line requires only 1–2 operators.
8. Robust, durable, stable, and reliable
The machine bed is a welded steel structure, tempered to relieve internal stress and prevent deformation.
The forming stands are made of cast iron and tempered to ensure high strength and a long service life.
Roll shafts are made of 40Cr steel, heat-treated (quenched and tempered) to a hardness of HB280.
Forming dies are made of GCr15 steel, hardened (quenched) to HRC 56–62.
The drive system utilizes a gearbox configuration; each forming stand is equipped with an independent gearbox, ensuring stable, high-intensity operation over long periods.
