Roll forming is a metal working process in which sheet metal is gradually bent into a desired cross-sectional profile through a series of roll stations. Stud and track roll forming machines are used to form studs and tracks from coiled steel which are used in wall framing and curtain wall systems in the construction industry.

Overview of Stud and Track Roll Forming Machines

Stud and track roll forming machines transform flat strips of sheet metal into studs and tracks with specific cross-sectional dimensions by passing them through a series ofpasses with contoured rollers. This continuous and automated process forms the strips into ‘C’ or ‘U’ shaped channels through cold roll forming without using heat.

Here are the key details about stud and track roll forming machines:

  • Function: To produce studs and tracks from steel coil in different sizes as per specified profile and cross-section
  • Working: Cold roll forming of sheet metal by progressively bending along a linear path through a series of rolls
  • Process: Coiled steel sheet is fed through a series of roller stations to gradually shape it into desired form. The number and contour of rollers determines the final shape.
  • المكونات الرئيسية: Uncoiler, feed rollers, breakdown rollers, finishing rollers, reform rollers, pre-punched holes station, shear and cut-off, stacker
  • محركات الأقراص: Electrical servo motor drives for each roller station
  • Automation: Fully automatic with controls for speed, feed and cutoff
  • المواد: Galvanized steel, stainless steel or aluminum coils of thickness 0.5 mm to 3 mm
  • Productivity: Up to 100 m/min forming speeds depending on thickness
  • الملفات الشخصية: ‘C’ shaped studs, ‘U’ shaped tracks, ‘L’ , ‘Z’ or custom profiles
  • Sizes: Thickness 0.5 mm to 3 mm, width up to 300 mm, web height up to 300 mm
  • التطبيقات: Walls, curtain walls, roof trusses, steel frames for buildings
  • المزايا: High speed, superior quality, consistency, reduced waste, low operation cost

There are two main types of stud and track roll forming machines:

النوعالوصف
Stud and Track Combo LinesMachines with flexibility to produce both studs and tracks on the same line as per application by quickly changing the rollers
Dedicated Stud or Track LinesMachines designed to produce only one profile i.e. either studs or tracks with fixed configuration of rollers

Key Differences:

  • Combo lines offer flexibility but lower productivity of around 60-70 m/min
  • Dedicated lines have higher output of up to 100 m/min but can make only one profile
  • Combo lines need quick tooling changeover; dedicated lines have fixed tooling
  • Combo lines take up more space; dedicated compact and less costly
  • Choose dedicated lines for mass production; combo lines for smaller volumes

Limitations and Challenges of Stud and Track Roll Forming

While providing many benefits, stud and track roll forming also poses some limitations and challenges as outlined below:

القيود

  • Not economical for low production volumes
  • Substantial initial capital investment required
  • Complex profile changes require roll tooling changes
  • Limited to using coil feed stock, cannot use sheets or blanks
  • Size limited by maximum coil width that can be handled
  • Adjustments needed when changing material thickness and grade
  • Professionals needed for operation, maintenance and repairs
  • Require separate punching process for punching holes
  • Not suitable for small-scale manufacturers

Challenges

  • Achieving profile tolerance and hole alignment as per standards
  • Troubleshooting breakdowns and line disruptions
  • Managing quick changeovers between different profiles
  • Handling coils without surface damage and tape residue
  • Maintaining consistent shape over long production runs
  • Training operators to run the line optimally

Automation and precision quality control at each stage is necessary to overcome these limitations.

Choosing Between Roll Forming and Fabrication of Studs/Tracks

Roll forming and fabrication are the two main methods used for producing studs and tracks. Here is a comparison between roll forming and fabricating them:

المعلمةتشكيل لفةالتصنيع
العمليةCold forming through progressive roller stationsCutting sections from sheets and structural fabrication
وقت الإعدادLow with quick changeoversHigh with multiple processes
Cycle timeVery low due to continuous operationHigher due to batch nature
العمالةأقل بسبب الأتمتةHigher due to manual processes
معدل الإخراجVery high up to 100 m/minLow 10-20 m/min
الجودةConsistent, good tolerancesVariable, depends on operator skill
Secondary workMinimal finishing requiredMilling, grinding, hole punching needed
التكلفةLower due to high productivity, low laborHigher due to multiple processes
المرونةLimited to profiles the rolls can makeVery high, any shape can be fabricated

Key Considerations:

  • Roll forming optimal for long and continuous production runs
  • Fabrication suitable for low volumes or custom profiles not possible through roll forming
  • Roll forming has faster delivery with minimal finishing work
  • Fabrication requires skilled workers for quality and consistency
  • Roll formed studs and tracks offer superior structural performance

For long production runs, roll forming is the preferred process with its speed, quality and cost benefits. But fabrication provides the shape flexibility for custom profiles.

التعليمات

Q: What are the typical production rates for studs and tracks?

Q: What are the typical maintenance needs?

A: Roller inspection, lubrication, hydraulic/pneumatic systems checks, fastener tightening, roll replacement when worn out.

Q: How quick are the changeovers between different profiles?

A: On combo lines, changeovers take 15-30 mins depending on number of rolls to be changed. Fixed profile machines have longer change times.

Q: What is the typical line layout?

A: It starts with the uncoiler, followed by feeding unit, breakdown section, pre-punching if needed, finishing stands, cut-off press and then stacker.

Q: What kind of training is required to operate these machines?

A: Comprehensive classroom and on-the-job training by technicians is recommended. Operators need training in machine setup, operation, safety and maintenance.

Q: What factors affect the total price of the roll forming line?

A: Speed, coil size handling capability, automation features, changeover design, and optional accessories impact the pricing. Brand and location influences price.

Q: What are the end applications for studs and tracks?

A: Main applications are wall framing, curtain walls, mezzanine floors, roof trusses and suspended ceiling grids. They form the structural skeleton for buildings.
