Rack Back Panel Roll Forming Line

1. Definition

A rack back panel roll forming line produces vertical enclosure panels for supermarket and warehouse shelving. The reference host uses servo width adjustment so about 100 / 200 / 400 mm finished widths share one forming train. Punch dies change for hole maps; cut knives adjust with width.

It is not a horizontal deck / shelf panel line, not a box-panel hoist-change plant, and not an upright or beam structural mill.

2. Process flow

1. Integrated decoil + level
2. Servo feed into punch (row holes + corner notches)
3. Roll forming (~14 cantilever closed gearboxes; one side fixed, one side servo slide)
4. Hydraulic cut with flange / fold
5. Exit

Public back-plate lines likewise sequence straighten → punch → form → hydraulic cut/bend. Treat competitor thickness or speed bands as industry context only.

4. Boundaries and conflicts

• Do not paste deck-panel thickness ~0.8 mm or forming ~11 kW onto back panel.
• Do not paste box-panel ~12–15 m/min / ~7.5 kW / A–B hosts here.
• Market back-plate ads may quote thicker gauges (e.g. 1.5–2.5 mm) for different products — that is not this proposal’s 0.4–0.6 mm band.
• Document header brands on some source sheets must be reconciled with the contracting party before publishing as “standard.”

5. Applications

Supermarket gondola backs, warehouse shelving rear enclosures, and light racking panels that need punched row patterns plus corner notches on thin strip.

6. Buyer FAQ

Same catalog leaf as deck panel — same machine?

Same product group, different configuration. Parameters, dies, and thickness stay on the back-panel sheet.

How does width change work?

One side of the cantilever gearbox train is fixed; the other slides under servo control to cover the 100 / 200 / 400 mm families.

Why is speed only 0–6 m/min?

Servo punch of row + corner features plus thin-gauge forming and hydraulic flange cut limit the working band on this proposal.

What drawings are mandatory?

Finished width family, hole map, corner notch geometry, thickness, and flange height after cut.
