    1. Definition

    A 6-inch half-round gutter machine (6英寸半圆天沟 / 圆天沟) cold-forms a semicircular eaves-trough profile from color-coated coil. The documented baseline uses a cantilever manual decoiler, about 18 bidirectional chain-driven passes, and PLC / touch-screen hydraulic cut-to-length.

    It is not a general rain-gutter (K-style class) line, not a box-gutter line, and not a downspout host. Specialty-pack indexes that point to the same 6-inch half-round product must not create a second conflicting parameter source — public ratings stay on this FAQ baseline.

    North American portable half-round machines often advertise about 30–35 ft/min class speeds with small single-phase drives. Treat those as market orientation only; do not overwrite the documented about 3–8 m/min / about 5.5 + 3 kW plant-line baseline.

    2. Process and applications

    1. Decoiling (cantilever; capacity about 1–2 T; coil width about 300 mm on that quote)
    2. Guiding / front shear
    3. Roll forming
    4. Hydraulic cut-to-length
    5. Exit / run-out

    Applications. 6-inch half-round eaves gutter / water-trough production for markets that specify semicircular collectors (heritage, architectural, or regional preference). Not a substitute answer for every “gutter machine” RFQ.

    3. Reference parameters (documented baseline)

    ItemDocumented reference
    Forming speedAbout 3–8 m/min
    Forming / hydraulic powerForming motor about 5.5 kW; hydraulic cut motor about 3 kW
    Drive / controlsCenter bidirectional chain (P=25.4); PLC + touch screen + VFD — brand not locked in source
    Passes / shaftAbout 18 rows; shaft about φ50 mm
    Frame / side plateAbout 250 H welded body; side plate about 22 mm
    EnvelopeAbout 8.8 × 0.7 × 1.0 m
    ThicknessAbout 0.4–0.8 mm color steel
    Typical compositionDecoiler, forming host, PLC / hydraulic cut — mainline only

    4. Boundaries

    • Rain gutter general line — About 10–12 m/min / 4.0 + 3.0 kW / φ70 — different proposal.
    • Box gutter — Do not fill missing box numbers from this half-round sheet.
    • Downspout + bender — Vertical pipe family; bender about 2.2 kW is not part of this host.
    • Other inch sizes of half-round — Confirm drawing; this page locks the documented 6-inch baseline.

    5. Buyer FAQ

    Why is speed lower than the rain-gutter baseline?

    Because the half-round quotation documents about 3–8 m/min. Do not force-merge with about 10–12 m/min rain-gutter wording.

    Which PLC brand should we publish?

    The source does not lock a single brand — write PLC + HMI + VFD without inventing an exclusive maker.

    Is this the canonical answer for every “round gutter” inquiry?

    It is the documented 6-inch half-round baseline. Other diameters need their own drawing and proposal.

    Can we add a pipe bender to this quote by default?

    No. Benders belong with downpipe lines.

    Final ratings follow the confirmed technical proposal. Price and lead time are out of scope.
