The key components of a cable ladder roll forming machine work in tandem to transform raw metal coils into finished cable ladder products. The forming stations apply high pressure using hydraulically controlled roller dies to gradually shape the strip into ladder side rails and rungs. Automated controls precisely regulate the feeding, punching, forming and cutting processes resulting in high dimensional accuracy and superior quality finished ladders.

Working Process

The working process of a cable ladder roll forming machine consists of:

1. Material Feeding – The strip coil is loaded onto an uncoiler which smoothy feeds the strip into the machine through an initial feeder rack. Guiding devices align the strip centrally as it enters the production line.
2. Punching – A computerized punching unit with programmable punches then creates holes in the strip for inserting cable ties/fasteners to the finished ladders later on.
3. Pre-forming – Initial roller dies lightly pre-bend the strip to prepare it for the forming stations. Pre-forming reduces stress on the metal during shaping.
4. Forming – The strip enters a series of progressive roller die forming stations – each station further bending and shaping the strip incrementally to gradually form the final cable ladder profile. Side rails and rungs are formed through careful caliberation of different steel thickness zones across the strip.
5. Hydraulic Pressure – Hydraulically activated cylinders provide pressure against the roller dies required for the forming and calibration. The pressure intensifies through each station ranging from 7 tons to 25 tons.
6. Cutting – Based on the input ladder length, a computerized cutting device accurately cuts each piece. Pneumatic or hydraulic shear machines are typically integrated for this purpose.
7. Stacking – The finished cable ladders are stacked systematically by an exit conveyor or stacker for easy loading and transport. Each ladder can range from 3 meters to 15 meters long.

Automated programmable controls coordinate the above processes in a seamless synchronized production sequence. Modern machines also include safety measures like strip break detectors, emergency stop buttons, sensor-monitored access doors and other features. The end result is mass production of cable ladders in the exact customized specifications provided by clients.

Material, Feeding, Forming and Slicing

A range of materials with thickness up to 3 mm can be formed into cable ladders of widths between 100 mm to 1000 mm by appropriately configuring the roll forming line. Smooth feeding, precise punching and cutting, and intensive hydraulic pressure applied through automated roller die forming enables production of superior quality ladders in high volumes.

Design and Customization

• Completely customized design – client provides ladder specifications
• CAD software generates roller die design to match ladder profile
• Forming stations caliberate roller dies to shape side rails and rungs
• Ladder height, width, rung spacing/size customized
• Hole punch patterns personalized for each client
• Bends, embossing, brackets optionally incorporated
• Support longitudinal and traverse cable rung direction

Clients have complete flexibility in design of the cable ladder end product. They can provide custom specifications like height, width, rung spacing, hole punch patterns etc. as per their desired cable routing requirements. Advanced CAD software translates the ladder design into specialized roller dies for each forming calibration station. This facilitates mass production of fully personalized and functional cable ladders catered exactly as per the client’s needs.

Maintenance

Pros and Cons

While cable ladder roll forming machines require significant initial investment and maintenance efforts, they enable efficient large scale manufacturing of lightweight, high strength products customized to client cable support requirements. The automated production ensures consistency in dimensional and structural quality.

Limitations

• Maximum 3 mm thickness coils
• Maximum 1 meter strip width capacity
• Maximum cable ladder heights up to 600 mm
• Restricted forming capability for extreme bends
• Rungs prone to damage if very thin
• Short step obstructions difficult to incorporate

The prime limitations of cable ladder roll forming pertain to restrictions in material thickness and product dimensions they can effectively shape. While offering extensive customization, abrupt contours and thin sections prone to breaking during forming remain key challenges. Robust ladder designs adequately overcoming such limitations yield the best production results.

Benefits

• Highly efficient continuous production
• Consistent quality end products
