Cable Tray Forming Machine

Kabelrinnen-Rollformmaschine

The cable tray forming machine is a fully automated integrated equipment combining cold bending and rolling processes. Utilizing PLC-based numerical control, servo drives, and hydraulic coordinated control systems, it processes various types of power cable trays—including trough, ladder, pallet, and long-span designs—from raw materials such as galvanized steel strips, cold-rolled steel plates, and aluminum alloy strips in a single setup. It finds extensive applications in large-scale production for building electromechanical systems, new energy sectors, chemical industries, rail transit, and data center cable trays. The machine integrates all manufacturing steps—raw material processing, forming, punching, cutting, and material discharge—eliminating the need for multiple separate machines while offering high automation and consistent forming accuracy. Detailed specifications of its key functions are provided below.

Functions of the integrated process flow for foundation construction

The equipment features a closed-loop integrated production line that enables fully automated processing from raw materials to finished cable trays, minimizing manual intervention throughout the entire workflow. The standard process includes: coil unwinding → leveling → feeding → punching → roll forming → length-specific cutting → automatic discharge and stacking, with all steps operating in synchronized coordination for seamless continuous-line production.

Automatic Uncoiling and Leveling: Paired with a hydraulic uncoiler, it enables automatic feeding of tonnage-grade steel coils and aluminum coils. Equipped with multiple leveling roller assemblies, it corrects sheet warping, wrinkles, and edge deformation, eliminates internal stresses in the sheets, ensures feed flatness, and prevents distortion or height variations in finished cable trays. Suitable for processing conventional cable tray sheets with thicknesses ranging from 0.8 mm to 3.0 mm.

High-precision servo feeding: Equipped with a servo variable-frequency feeding system featuring numerically controlled adjustment of feeding speed and length, with an error tolerance of ±0.2 mm. It ensures uniform-speed feeding, ideal for high-speed continuous production while preventing sheet slippage or misalignment, and supports adaptive feeding for both wide and narrow sheets.

Continuous cold bending roll forming: The core forming process utilizes 12–20 sets of high-precision custom rollers and employs a progressive multi-point pressure cold bending technique to simultaneously complete sheet bending, side flanging, bottom rib profiling, and groove forming, directly producing standard U-shaped, C-shaped, or stepped-edge cable tray structures. The resulting trays feature precise edges and structural strength that meet specifications, eliminating the need for secondary bending operations.

Hydraulic fixed-length cutting: Features a flying hydraulic cutting mechanism that performs continuous cutting after material formation without downtime, automatically cutting to preset lengths with smooth edges free of burrs and deformation. Supports custom-length cuts and is ideal for manufacturing non-standard-sized cable trays on construction sites.

Automatic discharge and stacking: The finished product outlet platform is equipped with a sensor-based sorting system that automatically discharges products from the cable tray and stacks them in layers. Users can configure stacking quantities and discharge intervals, facilitating packaging and transportation for workers while significantly reducing manual handling labor.

Multifunctional CNC punching machining capability

The device features a front-mounted CNC punching station, offering customizable single-row or double-row composite molds for processing all types of tray hole configurations. It eliminates manual drilling requirements while ensuring uniform hole precision and compliance with on-site installation standards.

Conventional hole machining: automatically stamps side connection holes, bottom mounting holes, and ventilation/heat dissipation holes; hole spacing, diameter, and number of punching groups can be set with a single CNC command.

Customized irregular holes:Replaceable molds for machining wiring slots, snap-fit positioning holes, and corrosion-resistant drainage holes, suitable for specialized engineering custom cable trays.

Mode switching: Supports one-click selection between punching mode and non-punching mode, enabling customized production of either punched or solid enclosed cable trays—significantly enhancing manufacturing flexibility.

Multi-specification adaptive modeling function

The next-generation CNC-controlled cable tray forming machine requires no disassembly for mold replacement, features rapid configuration adjustment, and is suitable for mass-producing cables of various types and sizes while complying with mainstream construction specifications in the market.

Stepless dimensional adjustment: The roller spacing and forming height are digitally controlled via electric actuators, typically compatible with cable trays ranging from 100 mm to 600 mm in width, with freely adjustable side heights and compatibility with both national and non-standard dimensions.

One-click profile switching: The parameter panel loads preset configurations, enabling instant selection between four profiles – slot-type fully enclosed cable trays, stepped hollow cable trays, integrated cover panels, and fire-resistant reinforced cable trays – without disassembling rollers or replacing frames.

Plate compatibility: Compatible with four types of raw materials—adaptive galvanized steel plates, color-coated steel plates, aluminum alloy plates, and stainless steel plates. The roller pressure and forming speed can be precisely adjusted to accommodate plates of varying hardness, preventing cracking of thin sheets and inadequate formation of thick sheets.

Intelligent Control and Operation Management Functions

PLC Human-Machine Touch Control: Equipped with an industrial touch display for visual configuration of length, quantity, hole spacing, speed, and specification parameters. It stores up to 100 product formulas, allowing direct parameter retrieval for subsequent production of identical items without repeated calibration—ideal for novice operators to learn quickly.

Automatic Fault Warning Protection: Equipped with an intelligent detection system for overload power failure, material jamming, punching misalignment, and hydraulic pressure deficiency. It automatically triggers shutdown alarms upon detecting abnormalities, displays the fault location on the screen, reduces equipment damage risks, and ensures production safety.

Automatic production counting statistics: Automatically calculates daily finished product output and good product quantity, with data export support for efficient workshop capacity assessment and production scheduling management.
