CNC Rebar Arc & Bend Machine

Overview

The Gongda GDWHWQ-36 CNC Rebar Arc & Bend Machine is a CNC-controlled rebar processing machine that forms arcs, hooks and bends in a single pass. It is built for precast concrete plants and rebar processing facilities that need repeatable, high-volume output of curved and hooked bars rather than separate manual operations. Gongda (China Rebar Machinery, chinarebarmachinery.com) is based in Hefei, Anhui, China, with a factory rooted in the electromechanical works of Hefei University of Technology, and exports rebar processing machines worldwide.

Key specifications explained

• Arc length (弯弧长度): 2600–5000 mm — the range of bar lengths the machine can form into arcs in one pass.
• Hook length (弯勾长度): 150–500 mm — the adjustable end-hook length produced together with the arc.
• Bending angle: 0–120° — CNC-programmable bend angle for arcs and hooks.
• Bending speed: 48–62 °/S — angular forming speed, supporting consistent cycle times.
• Minimum bending radius: 2600 mm — the tightest arc radius the machine will form.
• Air pressure: 0.6 MPa — required shop air supply.
• Arc & hook capacity (弯弧弯勾能力): Ø16:2 · Ø20:2 · Ø25:2 · Ø28:2 · Ø32:1 · Ø36:1 — the number of bars processed per cycle at each diameter, from two bars at Ø16–Ø28 down to one bar at Ø32 and Ø36.
• Dimensions: 9700 × 5000 × 2600 mm — plan the floor space and handling clearance accordingly.

Applications

The GDWHWQ-36 suits precast concrete production and rebar processing plants where curved bars, hooks and combined arc-and-hook geometries are required. Typical use cases include precast elements, tunnel segment cages, curved structural reinforcement and other formed rebar where the arc and hook must be produced accurately in one pass. Because arc length, hook length and bending angle are CNC-controlled, the model supports repeat batch production as well as changeovers between different bar geometries.

Why buy this model from Gongda

• One-pass arc and hook forming — reduces separate handling and secondary bending steps.
• Wide diameter coverage — handles Ø16 to Ø36 with defined bars-per-cycle capacity.
• CNC control — repeatable angles, arc lengths and hook lengths across production runs.
• Factory engineering background — rooted in the electromechanical works of Hefei University of Technology.
• Export experience — machines supplied to Russia, Spain, Latin America, the Middle East, Southeast Asia and Africa.
