CONTAINER HOUSE ROLL FORMING MACHINE

Specify the section and material for each line, including the tooling and changeover method for every required size.

Functional Faces First

Mark internal and external dimensions, return lips, angles, bend radii, thickness basis and contact faces from one stated datum system. Add left/right orientation, end holes, slots, notches and the real mating node. Keep cosmetic dimensions distinct from those that control assembly.

Revisions and Tool Access

Use one controlled revision across the component CAD, tooling list, hole programme, gauge and assembly drawing. A changed lip or radius can affect roller clearance, punch access and cut-off support even when the overall width is unchanged. Reassess those operations before treating a new section as a recipe change.

Agree the ordered section dimensions, material combinations and acceptance criteria in the equipment specification.

Define the drawing–material combination for each line. Strength, thickness, coating and section geometry together affect forming load, springback, punch clearance and surface contact.

Material window. State the steel standard and grade, yield and tensile limits, base-metal or total coated thickness, and thickness tolerance. Use material certificates and samples at the required grade and thickness limits to define each line’s operating window.

Surface route. Identify coating, visible side and acceptable contact marks. Pre-galvanized or prepainted coil, welded parts painted later and components galvanized after fabrication have different preparation and repair requirements.

Coil interface. Provide mass, inside/outside diameter, developed strip width, width tolerance and slit-edge condition. Coil handling changes the decoiler and layout; strip width, burr and camber affect alignment and the resulting part.

Develop strip width from the approved section and evaluate the intended material at its actual bend radii. Do not reduce thickness or substitute a stronger grade simply to fit an equipment window: either change also requires product-engineering approval. Use incoming-coil limits and surface samples to distinguish material defects from forming or handling marks.

Choose the hole-making and cutting sequence from the final part datums, tool access and section support. The top-beam hydraulic post-punching operation is separate from cut-off.

Load and guide the specified coil, establish feeding and lubrication, and form the approved section. Define punching and cut-to-length as separate operations in the line layout. At release, inspect length, hole-to-end relationship, cut angle and local end deformation; route unfinished notches, weldments or other end work to a named secondary process.

Pre-punch flat strip when the pattern is accessible before forming. A repeating pattern can suit this route, but features near bends can move or distort as the section develops. Relate the feed pattern and cut length to the finished part datum.

Post-punch the formed section when the required face is accessible and can be supported. Tool access and support can add cycle constraints; use the finished end as the locating reference where the design requires that relationship.

Use a secondary operation when geometry, batch size or access favours separate hole or end work. This adds handling and another locating setup, so use the same functional datums for setup and inspection.

Set the Bottom-Beam Sequence Independently

Define the actual holes, slots, end distances and cutting support for the selected bottom-beam drawing. Decoiling, camber adjustment and lubrication do not determine which hole patterns are included.

Check bottom-beam tool access rather than copying the top-beam punching arrangement. Put corner-node preparation, welded ends and remaining secondary work in the process BOM with their own owner and release point.

Approve a column at its working length and at both connection nodes. A good short end sample cannot establish full-length straightness, twist or assembly fit.

Check Three Conditions

1. Section and direction: returns, angles and mating faces at the required inspection points; clearly mark top/bottom and handedness.
2. Free-state shape: full-length straightness and twist on the agreed support arrangement, without forcing the part into a fixture to hide deviation.
3. Node fit: cut squareness, local distortion, clearance and contact at actual upper and lower connection samples.

Use representative length families, first and last parts and parts after a coil or setting change. Poor entry alignment, variable coil condition or inadequate runout support can each affect the result; diagnose the stage before adjusting the roll tooling.

Specify column holes, slots, welded ends and node machining as separate order items, with their tools, locating datums and acceptance checks. Include an in-line operation only when it is part of the selected configuration.

Select a door panel roll forming machine from the finished skin and receiving door assembly. Specify each required width, return height and direction as a drawing-controlled combination.

Door-Skin Family A

YX30-834 / YX25/32-834/1133. Match the requested working width, return and surface side to its own approved drawing.

Door-Skin Family B

YX30-524 / YX25/30/33/40-627/1148/1133. Define the tooling and changeover method for each required width, return height and material combination.

Define the Finished Skin

Specify assembly width, return height/direction, flatness, diagonal limits, cut-edge condition and the visible face. Include manual front-shear work and hydraulic post-cutting in the real sequence.

The skin is one part of a door. Assign lock/hinge openings, embossing, remaining edge work, cores, frames and hardware to their required downstream operations, then check a skin in the receiving door assembly.

Prove the Size Change and Surface

Identify the powered adjustment axes and the guide, blade, die or receiving settings that remain manual. Separate motorized size adjustment from operator work on guides, blades and dies.

Run the intended A and B skins in the specified material. Record tools, settings, operator work, trim, cut clearance and the first accepted skin. Check roller contact, surface comparison samples and final assembly fit before releasing that combination.

Classify the change before asking how long it takes. Length recipes, size adjustments and new cross-sections create different mechanical and inspection work.

Same section, different cut length

Length setting, hole sequence, final-end relationship and receiving support

Release: First part matches the length and hole/end drawing

Size within an approved family

Specified powered axes plus any manual guides, blade/die and support settings

Release: Only the drawing–material combinations on the approved matrix

Tooling or mechanical change

Correct roller, punch, cut-off tool and setting IDs; alignment and safe setup

Release: Controlled tool list and accepted first part

New section, grade, radius or access condition

Reassess the forming sequence, load, support and tooling for the new section or material

Release: A defined revised configuration and trial, rather than a stored PLC recipe

Last accepted A. Start the changeover clock at the agreed last-good-part point.

Change and set. Record labour, tools, settings, coil/threading changes and material used.

First accepted B. Stop only after measurement and first-part release; separate adjustment scrap from good parts.

Return to A. Restore the controlled mechanical settings and verify recovery, not just recipe recall.

Use the real order sequence and the staff who will operate the line. A dedicated line can avoid frequent mechanical changes but needs enough recurring demand; a flexible arrangement can serve a wider mix while adding setup and inspection time. Specify adjustment axes, tooling and trial conditions separately for each beam, column or skin line.

Inspect functional dimensions from a defined datum and measurement state, then prove the node and frame interface. A single general ± value cannot cover section shape, holes, ends, straightness and twist.

Section and interfaces. Check returns, angles, radii and contact dimensions using the controlled drawing and agreed measurement points or gauge. Include drainage/seal faces and adjoining parts in the tolerance stack.

Holes, length and ends. Use common functional datums for hole-to-end distances, slots, cut angle and local deformation. These features control fastener access, node location and fixture loading.

Full-length shape. Measure straightness and twist in the agreed free state or support condition. Do not use clamping to conceal deviation.

Surface and edges. Use material-specific limit samples for marks, coating damage and burrs. Separate incoming-coil, forming, welding and transport causes; repair follows the actual coating specification.

Assembly and batch changes. Trial-fit nodes and full-size frames and use cross-batch parts where interchangeability is required. Inspect first/last parts and after coil, tool or maintenance changes.

Allocate tighter tolerances only where the assembly needs them: more demanding limits can change tooling, gauges, process control and inspection time. Release reworked parts before counting them as good output. Set surface acceptance and repair methods for the actual coating route; pre-coated coil and post-fabrication galvanizing need different procedures.

Agree the trial inputs and acceptance basis before running the machine. FAT checks the contracted configuration; SAT checks operation after installation, while factory production release remains a separate decision.

Before FAT. Fix the component/material matrix, drawing revisions, tool versions, tolerances, gauges, quantities, trial duration and signatories. Name who provides coils, mating nodes, fixtures and any sample-frame or welding work.

During FAT. Run representative continuous orders and boundary combinations, including first/last parts, coil changes, hole/end/surface checks and A→B→A recovery. Record accepted output, time basis, scrap/rework, settings, tools and supplied safety functions.

During SAT. Check utilities, supports, transport-related setup, local material, handling and operator recovery. Repeat the agreed part checks and close site-dependent items.

For production release. The buyer’s manufacturing and product-engineering team separately accepts downstream fit, joining, finishing and packing under its production controls.

For a nonconformity, record the affected drawing/material condition, action, owner and retest. Close each defect with a recorded corrective action and a successful retest under the agreed conditions. Joint node/frame tests require their own agreed fixtures, materials and inspection method.

Plan the complete operating envelope: unloading and threading coils, supporting long parts, inspection, maintenance and safe access. A footprint that fits the main machine alone is insufficient.

Layout and Utilities

Provide the building CAD, coil mass/diameters, lifting capacity, electrical supply and existing downstream locations. The equipment layout should show loading clearance, feed direction, runout length, inspection/buffer zones, maintenance space and vehicle/pedestrian routes. Confirm actual loads and utility requirements from the selected equipment list.

Controlled Handover

List mechanical, electrical and hydraulic documents; operating instructions; recipe permissions and backups; mechanical setting sheets; tool IDs and orientation; blade/die maintenance; spares and consumables. A recoverable setting includes physical positions and tool condition as well as control data.

Team Readiness

Have the operating and maintenance team demonstrate safe threading/setup, first-part inspection, abnormal-stop recovery and restart after maintenance. Include an actual changeover where relevant. Define installation, training and support deliverables, responsibilities, costs and timing in the order.

For projects in the United States, Saudi Arabia, Russia, India and Mexico, identify the site, intended use and documentation route. Flat-pack building components and machine documents do not establish freight-container compliance or building structural, fire or weather performance.
