Automatic Rebar Cutting and Threading Line

Automatic Rebar Cutting and Threading Line 

In modern infrastructure construction, processing precision and operational efficiency directly determine project timelines and structural integrity. The Automatic Rebar Cutting and Threading Line from Shandong Zhongji Luyuan Machinery Co., Ltd. represents a fully integrated CNC solution that consolidates raw material feeding, high-precision hydraulic sawing, and parallel thread rolling into one continuous workflow.

Engineered for requesting applications over high-speed rail, atomic control offices, and high-rise secluded development, this framework forms rebar breadths extending from Φ16 to Φ50 mm with a cutting exactness of ±1 mm/m and threading exactness that meets Review I mechanical join benchmarks. With an introduced add up to control of 19 KW and generation proficiency coming to 80–120 pieces per hour, your office picks up the capability to work ceaselessly whereas killing the security dangers and quality irregularities characteristic in manual forms. Built with a fortified mechanical steel outline and controlled by an brilliantly CNC touch screen framework, this line guarantees repeatable, traceable yield for ventures where zero-defect threading is non-negotiable.

Why Choose Our Automatic Rebar Cutting and Threading Line

Seamless Process Integration

You no longer need to coordinate separate workstations for cutting, threading, and grinding. Our Automatic Rebar Cutting and Threading Line combines all three operations into one compact footprint measuring 29,000 × 3,800 × 2,450 mm. This integration eliminates manual handling between stations, reduces material loss, and accelerates your production cycle.

The system's servo-driven bolstering component and pressure driven clamping strategy guarantee millimeter-perfect situating some time recently each cut. Your administrators basically stack crude stock onto the fabric rack, input length parameters by means of the PLC touch screen, and oversee output—one individual can oversee the whole line.

Precision That Meets Structural Engineering Standards

Every thread profile and shear surface is critical when mechanical couplers must transfer load across thousands of reinforcement joints. Our system delivers:

• Length tolerance: ±1 mm/m across the full 1.5–12 m range
• Sawing feed speed: Stepless adjustment for different rebar grades (HRB400, HRB500)
• Thread pitch accuracy: Full and uniform threads with depth consistency verified by Go/No-Go gauges

Flat, perpendicular sawing end-faces eliminate the need for secondary grinding in most applications. Burr-free, smooth cuts protect coupler threads and reduce on-site rejection rates, safeguarding your project's compliance with seismic and structural codes.

High-Efficiency Production for Large-Scale Projects

When your project demands rapid fabrication of thousands of threaded reinforcement bars—such as bridge pier cages or precast tunnel segments—downtime and slow cycle times directly impact the critical path. This line achieves:

• Steel bar conveying speed: 90 m/min
• Daily output: Supports 24-hour continuous operation with a low failure rate
• Fast model changeover: Compatible with multiple diameters; adjust parameters in minutes

Your rebar processing center can fulfill orders faster, reduce inventory holding periods, and respond dynamically to design changes without bottlenecking downstream construction schedules.

Labor Savings and Enhanced Workplace Safety

Traditional rebar threading relies on portable machines operated by multiple workers in hazardous environments—cutting injuries, repetitive strain, and coordination errors are common. Our fully automatic system requires only one operator to supervise the entire production line.

Heavy lifting, precise measurement, and blade handling are automated. Hydraulic clamping and electric high-speed shearing minimize manual intervention, reducing workplace injuries and lowering insurance premiums while improving overall site safety compliance.

Technical Specifications

Core Applications

High-Speed Rail and Bridge Infrastructure

When constructing elevated viaducts or cable-stayed bridge piers, you need to produce reinforcement cages with thousands of mechanical couplers under strict dimensional control. Our Automatic Rebar Cutting and Threading Line handles mass production of precast segment reinforcement, ensuring that every threaded bar fits perfectly within tolerance bands required by dynamic load calculations and seismic design codes.

Nuclear Power and Hydroelectric Projects

Containment structures and dam spillways request ultra-high-strength fortification with zero-defect threading and full traceability. The computerized line's PLC framework logs each cutting and threading operation, giving the documentation essential for administrative reviews. Reliable string profundity and pitch dispose of frail joints that might compromise auxiliary judgment beneath extraordinary operational stresses.

High-Rise Modular Construction

Urban development destinations with restricted space advantage from off-site rebar production lines that create standardized strung bars at scale. Your coordinations group conveys pre-threaded fortification coordinated to floor-by-floor plans, empowering fast get together with mechanical joins instep of time-consuming lap welding. This approach abbreviates your development cycle and diminishes on-site labor congestion.

Quality Control and Performance Assurance

Multi-Stage Inspection Protocol

Before shipment, every system undergoes rigorous testing:

• Thread Profile Confirmation: Utilizing accuracy gages to affirm pitch distance across and string profundity consistency over test batches.
• Shear Surface Verticality: Laser arrangement checks guarantee the rebar end-face is cut at precisely 90 degrees to anticipate coupler misalignment.
• 24-Hour Push Test: Persistent operation checking tracks water powered liquid temperature solidness, PLC rationale precision, and edge wear patterns.
• Calibration of Uprooting Sensors: Encoder-based measuring units are confirmed to keep up ±1 mm precision over long-distance feeds.

Durable Components and Maintenance Accessibility

Shearing edges and string rollers are solidified to HRC 58–62, competent of withstanding the grating nature of HRB400 and HRB500 review rebar. The strengthened mechanical steel outline minimizes vibration amid high-speed threading, amplifying component life expectancy and diminishing impromptu downtime.

Modular plan permits your support group to supplant wear parts rapidly. Basic water powered seals, orientation, and cutting edges are open without dismantling the whole machine, keeping your line operational amid planned upkeep windows.

FAQ
