Applications of Guide Rail Roll Forming Machines

guide rail roll forming machine is an essential equipment used for producing various types of guide rails through the continuous bending and forming of a metal coil strip. Guide rails are widely used across many industries to provide guiding, positioning, and supporting functions in linear motion systems. This article provides a detailed guide on guide rail roll forming machines covering their working principles, main components, types, technical specifications, applications, installation, operation and maintenance procedures.

Overview of Guide Rail Roll Forming Machines

Roll forming is a continuous bending operation in which sheet or coil metal stock is progressively formed into a specified cross-sectional profile through a series of consecutive sets of rolls. Guide rail roll forming machines use this technique to transform metal coil strips into finished guide rail profiles through a series of processes including feeding, rolling, cutting and punching.

The forming rolls are arranged in stands for shaping the strip into the desired contour as it moves through the machine. The number of roll stands required depends on the complexity of the final profile. Corrective rollers may be used for precision forming. Punching units cut holes and notches while cutoff devices cut the formed rails to length.

Guide rail roll forming machines offer efficient and cost-effective production of long length guide rail profiles in large quantities without the need for pre-cut metal blanks. They enable fast changeover between different guide rail shapes using the same machine. Automated operations, good dimensional accuracy and excellent surface finish are other advantages.

Main Components of Guide Rail Roll Forming Machines

The major components of a standard guide rail roll forming machine are:

Table: Main components of guide rail roll forming machines

UncoilerHolds the coil of sheet metal and feeds it into the roll forming line at a suitable tension
Feed tableSupports the strip and guides it into the forming section
Forming rollsProgressive sets of rolls that gradually shape the metal strip into desired profile
Punching unitsPunches holes, slots and notches at specified locations
Cutoff shearCuts formed rails to required length
Supporting rollsProvide support and prevent sagging of formed profile
डेकोइलरTakes up the finished product
कंट्रोल पैनलHouses electrical, automation and safety systems

The uncoiler and decoiler allow continuous production by joining the trailing end of the exhausting coil to the leading end of a new coil and collecting the finished rails into a coil.

Applications of Guide Rail Roll Forming Machines

Guide rail roll forming machines are versatile equipment suitable for producing all kinds of guide rails used in diverse applications:

Table: Major applications of guide rail profiles

RailwaysGuide rails for wagon lifts, turntables
ElevatorsGuide rails for lifts, escalators

Almost any industry using linear motion technology relies on guide rail profiles suitable for their specific application requirements.

Installation and Commissioning

Proper installation and commissioning procedures must be followed to ensure smooth operation of guide rail roll forming machines:

  • The machine should be placed on a flat, leveled surface and securely bolted down. There should be sufficient space around for coil loading and finished product offloading.
  • Roll forming lines operate at high speeds so vibration isolation mounts should be used underneath the machine frame.
  • Electrical connections must be made correctly by a qualified person adhering to local safety norms. The control panel requires both power supply and stable grounding.
  • Trial runs should be performed and forming parameters fine-tuned to achieve guides rails with correct dimensions and geometry. Test pieces should be physically measured.
  • The decoiler unit must be set up properly with the correct tension to take-up the finished rails without deformation.
  • Safety guards, light curtains and emergency stop circuits should be checked before regular production.

Operation and Working Principle

The typical operation sequence and working principle of guide rail roll forming machines is as follows:

  1. A coil of sheet metal strip is loaded on the powered unwinding reel and threaded through the guiding rolls into the forming section.
  2. The strip is fed incrementally through successive sets of profiled rolls which gradually bend it into the final guide rail shape.
  3. Supporting rolls stabilize the formed section while punching units create holes as required.
  4. At specific intervals, cutoff blades shear the rails to the desired cut length.
  5. The finished guide rails exit the machine and are taken up by the powered recoiling reel.
  6. Automatic sensors monitor the line and control the speed of rotation, strip tension and other parameters.
  7. If multiple rails are being formed, splitters separate them before recoiling.
  8. When one coil is fully consumed, the trailing edge is welded to the next coil and fed in without stopping production.

Maintenance and Precautions

Regular maintenance activities are vital for trouble-free operation of guide rail roll forming machines:

  • Rolls, bearings, shafts and gears should be lubricated as specified by the manufacturer.
  • Worn-out or damaged forming rolls should be refurbished or replaced to maintain profile accuracy.
  • Punching tool blades need to be sharpened periodically to cut holes cleanly.
  • Cutoff blades must be kept sharp for clean shear cuts and long service life.
  • All motors and drives should be kept in good condition. Wiring has to be checked for integrity.
  • The machine must be kept clean and dry. Debris should not collect in the working parts.
  • Staff operating the machine must be provided safety training and personal protective equipment.
  • Unexpected vibration or abnormal noise should be investigated immediately and addressed.
  • Technical manuals must be referred for maintenance schedules, spare parts codes and troubleshooting guides.
