Key Components of Mini Roll Forming Lines

Mini roll formers consist of several key sections engineered to operate in sync to form quality profiles continuously:

Table – Main Components of a Mini Roll Former

डेकोइलरUnwinds the flat coil stock and feeds into line. Has powered unwinding system and coil holding mandrel.
Feeding UnitGrips sheet using rollers/chains and feeds at constant speed into forming section.
Pre-cutterShears the coil to pre-cut strips before forming as per profile length.
फॉर्मिंग स्टेशनSeries of pyramid style roller dies that gradually bend the strip through each station to form the profile.
Control CabinetHouses the PLC, HMI, drives and electrical components. Allows programming and monitoring.
Main DriveGeared motor that powers the decoiler, feeding, forming sections in sync.
Post-cutterCuts the formed profile to desired length as per production requirements.
StackerNeatly stacks or collects the finished profiles.

The smooth interaction between these sub-systems results in continuous, high speed and precision roll forming.

Working Principle of Mini Roll Forming Machines

Here are the key steps in the functioning of mini roll forming lines:

  1. Decoiling – The metal coil sheet is held on a powered unwind mandrel. It gets unwound and released into the feed section.
  2. Feeding – Gripper rolls/chains engage the strip and feed at a constant speed into the forming section.
  3. पूर्व काटने – The feed length is pre-cut to length of the final part by built-in shearing blades.
  4. Forming – The pre-cut length moves through consecutive pyramid style roll stations. Each station progressively bends the strip to the desired profile shape.
  5. पोस्ट में कटौती – End cutters trim the profile to the final required length as per production needs.
  6. Stacking – Formed parts are neatly stacked for easy handling and packaging.

The feeding speed, roll gaps and sequencing are programmed into the PLC which coordinates the process for continuous production. Advanced 3D simulation softwares are used to visualize the optimal roller sequencing and die layouts before manufacturing the rolls.
