Haihui CNC Rebar Bending Machine: 40-Series Configurations
The supplied 40-series specification sheets describe three configurations. Choose the version to match your bar diameter, steel grade and workload; the figures below belong to separate configurations and should not be combined into a single machine specification.
| Specification | Gear-drive version | Variable-speed worm-drive version | Heavy gear-drive version |
|---|---|---|---|
| Listed bar capacity | 6–25 mm ribbed rebar | 6–28 mm* | 6–28 mm* |
| Transmission | Gear transmission | Worm-gear transmission with speed adjustment | Gear transmission |
| Motor power | 3 kW | 3 kW | 3 kW |
| Listed dimensions | 850 × 730 × 720 mm | 850 × 730 × 720 mm | 850 × 760 × 730 mm |
| Machine weight | 200 kg | 200 kg | 220 kg |
| Additional specification | Initial oil fill supplied, according to specification sheet | Listed initial oil quantity: 7–8 kg; confirm lubricant requirements | Worktable plate thickness: 10 mm |
*The 6–28 mm sheets do not identify the steel grade. Ask Haihui to confirm the permitted diameter for your actual material before ordering. The “40 series” designation is not a claim that every version bends 40 mm rebar. Dimensions and configurations are subject to final order confirmation.
Key Features
Digital Bending Angle Settings
The front-mounted digital controller provides an accessible interface for setting bending tasks. Repeated angle settings help operators prepare batches of similar reinforcement components. Confirm the controller functions and available angle range for the selected version.
Rotating Disc and Positioning Blocks
The circular work disc and perforated positioning blocks provide locations for bending pins and bar positioning. Select the tooling and bend radius for the bar diameter and reinforcement drawing. The correct setup is essential for consistent results.
Compact Wheeled Cabinet
The cabinet integrates the drive and control components beneath the worktable. Wheels assist movement within the workshop; secure and position the machine appropriately before operation. Provide adequate support for long steel bars.
Choice of Transmission
The supplied range includes gear-drive and variable-speed worm-drive configurations. Specify your processing requirements so Haihui can identify the appropriate version rather than selecting only by the series name.
Applications for This CNC Steel Bar Bender
- Preparing bent reinforcement bars for building projects.
- Batch bending in rebar fabrication workshops.
- Making hooks, L-bends and other bends allowed by the selected tooling and machine configuration.
- Reinforcement preparation for precast concrete components.
Operation and Maintenance
This machine bends pre-cut bars; bar loading and positioning require operator involvement. Check the bending pins, guards, electrical supply and work area before use. Follow the supplied operating manual, approved bending direction and rated capacity. Do not overload the machine or process multiple bars unless explicitly permitted by the manufacturer for that configuration.
Although some source sheets describe particular versions as maintenance-free, routine inspection remains necessary. Confirm the lubrication arrangement for the exact gearbox. The worm-drive sheet lists an initial oil quantity of 7–8 kg, while the gear-drive sheet states that the initial oil fill is supplied. Do not transfer one version’s oil instructions to another.
Frequently Asked Questions
What is the capacity of the Haihui CNC rebar bending machine?
The supplied gear-drive sheet lists 6–25 mm ribbed rebar. Two other 40-series sheets list 6–28 mm without specifying steel grade. Haihui should confirm the capacity against your material strength and selected configuration.
Is this an automatic coil-fed stirrup machine?
This product is a worktable-type bar bending machine for pre-cut steel. For equipment integrating coil feeding, straightening, bending and cutting, explore our CNC rebar stirrup bending machine.
Which motor power is listed?
All three supplied 40-series sheets list a 3 kW motor. Confirm voltage, phase and frequency before placing an order.
What information is needed for a quotation?
Send the bar diameter, steel grade, desired bend shapes, daily quantity, preferred transmission, power supply and delivery country. Ask for configuration-specific specifications and a working video.
