How to Select an Engel Roll Former

Key factors when selecting an Engel roll forming system:

  • Production requirements – Desired hourly output rate, coil widths/gauges, complexity of profiles to be produced.
  • Otomasyon ihtiyaçları – Determine if manual or powered material handling, part cutoff, and stackers are required.
  • Takımlama – Evaluate availability of standard tooling packages for desired profiles from Engel.
  • Kontroller – Determine necessary functionality like recipe storage, data logging, etc.
  • Teknik Destek – Engel provides installation support, training, and service. Ensure regional availability.
  • Özelleştirme – Engel can provide customized features, safety add-ons, and instrumentation.
  • Genişletilebilirlik – Select a system that can have capacity increased in the future with capability to add additional passes.

Work with Engel application engineers early when specifying equipment to get a system tailored to your production requirements.

Rulo Kalıp Tasarım İlkeleri

Proper roll tooling design is key to producing quality roll formed parts efficiently on an Engel machine. Design guidelines:

  • Optimize part profiles for material flow and stiffening ribs, seams, and embossments to add rigidity.
  • Engineer roll contours to guide material through forming without thinning, tearing or cracking.
  • Design forming passes and roll penetration carefully to control stresses induced in material.
  • Match roll diameters top-to-bottom to ensure even bending and precise tolerances.
  • Lubricate rolls to reduce friction – use materials like urethane that support metal flow for hard alloys.
  • Reduce sharp bend angles which concentrate stress by using larger radii bends.
  • Annotate tooling drawings thoroughly with pass sequences and references to aid setup and changeovers.

Work jointly with Engel tooling engineers to arrive at optimal roll designs and sequences for robust production.

Preparing for Engel Roll Former Installation

To prepare for arrival and installation of a new Engel roll forming system:

  • Arrange for electrical supply required – confirm voltage, capacity. Install disconnects.
  • Provide adequate space with clearances for safe operation around machine. Allow for part conveyors.
  • Obtain any necessary permits – building, electrical, local codes.
  • Prepare rigid foundations according to Engel specifications to handle loads.
  • Have lifting equipment available – cranes, forklifts, chains etc. to offload components from trucks.
  • Schedule qualified technicians for installation, alignment, wiring, and debugging.
  • Order initial tooling packages and material coil stock to have on hand.

Thorough planning minimizes delays and issues when the equipment arrives onsite.

Installation Best Practices

Recommended practices when installing Engel roll formers:

  • Carefully offload components from trucks using appropriate lifting devices. Avoid damage.
  • Follow Engel documentation for proper assembly sequence and alignments.
  • Have electricians install power connections and control wiring per electrical prints.
  • Anchor machine securely to flooring – forming induces dynamic loads.
  • Install all safety guarding before powering up machine. Eliminate pinch points.
  • Validate proper jog direction on drives prior to running. Reverse as needed.
  • Gradually power up and cycle machine to confirm correct operation.
  • Make roll adjustments from infeed to exit end to debug tooling pass by pass.
  • Only release for production after successful commissioning trials prove out line.

Careful installation by qualified personnel helps avoid issues and ensures a smooth startup.

Rulo Şekillendirme Operasyonu ve Kalite Kontrol

To safely operate an Engel roll former at optimal quality:

  • Monitor line speed, web alignment, roll loads, and other variables continuously. Make adjustments as needed.
  • Frequently check formed part dimensions using go/no-go gauges. Ensure within tolerance.
  • Ensure input coil parameters match Engel recommendations – thickness, width, tensioning, lubrication etc.
  • Promptly replace any worn roll segments before scratches form on parts.
  • Schedule downtime for preventative maintenance during planned production stops.
  • Implement programmed safety stops and light curtains that halt operation when a fault occurs.
  • Control lubrication levels and top up reservoirs as needed to support continuous high speed operation.
  • Ensure operators are properly trained on all procedures and safety precautions.

Consistent quality output requires continuous monitoring, training, and disciplined operation within proven parameters.

Rulo Şekillendirici Güvenlik Hususları

Important safety practices when operating Engel roll formers:

  • Comprehensive operator training on hazards and proper procedures.
  • Adequate guarding around all pinch points, gears, coils. Avoid exposed hazards.
  • Lockout/tagout for maintenance activities and clearing jams. De-energize machine.
  • Enforce PPE requirements including snug clothes, gloves, glasses, and hearing protection.
  • Clearly mark out safety zones around machine. Follow any access rules.
  • Implement automatic safety stops for unsafe conditions like line jams.
  • Şekillendirme alanındaki hava kalitesini iyileştirmek için gerekirse toz toplama.
  • Regular safety inspections to proactively identify risks – document corrective actions.

Prioritizing safety improves work conditions and prevents injuries. Follow all regulatory requirements.

Hakkında SSS Engel Rulo Şekillendirme Makineleri

Q: What types of metals can be roll formed on an Engel machine?

A: Most ductile metals including steel, stainless steel, aluminum, copper alloys. Softer, thinner material forms easiest.

Q: How long does it take to set up tooling for a new profile?

A: On quick change machines, typical setup time is 1-3 hours including pass debugging. More difficult profiles may take longer.

S: Hangi kalınlık aralığında rulo şekillendirilebilir?

A: Standard Engel models accommodate thicknesses from 0.5 mm to 4.75 mm (26 ga to 3/16”). Special models available outside this range.

Q: What factors determine maximum production speed?

A: Material thickness/hardness, part complexity, available horsepower, and desired quality determine maximum stable speed.

Q: How are roll formed parts cut to length?

A: Servo-operated cutoff presses or saws automatically cut parts to length at preprogrammed intervals. Lengths up to 65 ft are possible.

Q: What tolerances are possible with roll forming?

A: When maintained properly, roll formed parts typically hold dimensional tolerances around ±0.5 mm (±0.02 in). Tighter tolerances become difficult.

Q: How often must roll tooling be replaced?

A: On average every 1-3 months for high production 24 hour operations. Quick change tooling reduces downtime for replacement.

Q: What safety precautions are most important?

A: Training, guarding, lockout, marked safety zones, dust collection, interlocks, modification control, PPE, and periodic auditing.

Q: Can custom roll formed profiles be made?

A: Yes, Engel engineers can design custom tooling packages to produce specialized non-standard parts based on application requirements.
