Pre stressing anchorages with coiled spring type spiral bars and other specifications, fully automatic hydraulic high-speed railway spiral bar forming machine

Pre stressing spiral reinforcement machine with specifications such as coiled spring spiral reinforcement, usually refers to a fully automatic hydraulic CNC spiral reinforcement forming machine, which can integrate steel bar straightening, coiled/spring spiral forming, and cut to length. It is suitable for 4-22mm round steel/threaded steel and focuses on high precision and efficiency. It is the core equipment for prestressed engineering such as bridges, high-speed railways, and pipe piles. The following will explain the core information, structural principles, technical parameters, application scenarios, and selection points.
1、 Core positioning and functions
This type of equipment is specifically designed for the processing of coiled and spring-loaded spiral bars for prestressed anchors, which can replace traditional manual/semi mechanical processing and solve the pain points of low efficiency, poor accuracy, and unstable quality. The core functions include:
Automatic straightening: Continuously straighten the round/spiral steel bars to eliminate the original bending stress.
Precision molding: Roll circular or spring type spiral bars according to preset inner diameter, pitch, and number of turns, suitable for circular/flat spiral bar requirements.
Cut to length: Hydraulic driven cutting mechanism, cutting length error ≤ 5mm, rounding error ± 0.5mm.
Batch production: supports parameter storage and batch setting, can continuously process whole bundles of steel bars, greatly improving production capacity.
2、 Structure composition and working principle
1. Core structure
Functional Description of Key Components in the System
The power system's electric motor, hydraulic pump, and cycloidal motor provide stable power, while hydraulic transmission reduces gear clearance and ensures smooth operation
The straightening wheel group, rounding assembly, and pitch adjustment mechanism of the forming system are responsible for steel bar straightening, spiral forming, and precise pitch control
The cutting system cuts off the hydraulic drive of the oil cylinder and cutting blade for quick cutting, with a smooth and burr free cut
Control system PLC/microcontroller, touch screen, encoder parameter input/storage, digital display, positioning and meter measurement, with minimal error
The body structure box frame has strong rigidity, deformation resistance, and ensures long-term high-precision operation
2. Workflow
Loading: Round steel bars are placed into the feeding rack and inserted into the straightening wheel group.
Parameter setting: Enter parameters such as steel bar diameter, spiral inner diameter, pitch, number of turns, cutting length, etc.
Automatic processing: The motor drives the oil pump, the hydraulic components drive the straightening system to feed, the rounding assembly completes the spiral forming, and the cutting cylinder cuts upwards.
Discharge: The finished product automatically drops and can be continuously processed in a loop.
3、 Key technical parameters (mainstream models)
The following are common YGW series parameter references, with slight differences among different manufacturers:
Model: Suitable for steel bar diameter, bending ring diameter, motor power, travel speed, external dimensions (mm), weight (kg)
YGW-10 6-10mm 20-200mm 5.5KW 20-40m/min 1500×800×1500 700
YGW-12 8-12mm 20-500mm 9.5KW 20-40m/min 2000×1000×1700 900
YGW-16 10-16mm 50-800mm 11.5KW 20-40m/min 2200×1000×1700 1000
YGW-22 16-22mm 100-1000mm 16.5KW 20-40m/min 2600×1000×1800 1300
4、 Core advantages
High efficiency: Traveling 20-40 meters per minute, completing one finished product in about 10 seconds, which is tens of times more efficient than manual labor.
Accurate: Rounding error ± 0.5mm, cutting length error ≤ 5mm, adjustable pitch/inner diameter, meeting prestressing construction specifications.
Easy to operate: The CNC system supports parameter storage and one click start, reducing manual dependence and training costs.
Strong durability: Key components are mostly imported, the hydraulic system is stable, the box shaped body is fatigue resistant, and the maintenance cost is low.
5、 Application scenarios
Transportation infrastructure: prestressed components such as high-speed railway bridges, elevated bridge piers, pipe piles, subway sleepers, tunnel anchorages, etc.
Construction engineering: Processing of spiral stirrups for large roof trusses, pile foundations, ground anchors, and photovoltaic/wind power foundations.
Prefabricated component factory: Mass production of prestressed anchor fittings with spiral reinforcement, suitable for pre tensioning/post tensioning construction.
6、 Selection and usage points
Selection criteria: Select the corresponding machine model based on the diameter of the steel bar, the maximum inner diameter of the spiral reinforcement, and daily production, avoiding "big machine for small use" or "small machine for big use".
Daily maintenance: Regularly check the hydraulic oil level/cleanliness, straightening wheel wear, cutting blade sharpness, and keep the electrical system moisture-proof and dust-proof.
Safety regulations: Before starting up, check the protective devices, and operators need to be trained to avoid unauthorized operations.
7、 Summary
This equipment is an automated solution for prestressed spiral reinforcement processing, which has the characteristics of high efficiency, high precision, and easy operation. It has become a core equipment in modern infrastructure to replace manual labor, significantly improving project quality and construction progress.
