We offer a comprehensive range of precision metal processing equipment, including straightening, cold drawing, pointing, chamfering, cutting, thread rolling machines, and drawing dies, tailored for tube, bar, and wire materials across diverse industries.
The Rod Hydraulic Cold Drawing Machine is built for precision reduction of solid round bars, where dimensional consistency, straightness, and surface condition are critical to the finished part. Hydraulic drawing pulls the bar through a precision die to reduce diameter and improve roundness while cold work hardening increases strength and hardness. With drawing forces of 50–20,000 kN, speeds up to 30 m/min, and strokes up to 25 m, it handles carbon steel, stainless steel, alloy steel, tool steel, copper, and other metals for shafts, fasteners, bearing rollers, and precision bars.
The Rod Hydraulic Cold Drawing Machine is a precision solid-section forming equipment manufactured by FangRong Precision Machinery, a company with 26 years of dedicated expertise in designing, engineering, and producing cold drawing solutions for the metal bar and rod industry. Since its founding in 1998, FangRong has grown into a globally recognized manufacturer, serving over 10,000 customers across more than 70 countries.
The Rod Hydraulic Cold Drawing Machine is a hydraulically powered metal processing system designed specifically for the cold drawing of solid round bars and rods. It processes solid materials---including carbon steel bars, stainless steel rods, alloy steel bars, aluminum rods, copper rods, titanium bars, and specialty alloy rods---at ambient temperature to reduce diameter, improve surface finish, enhance straightness, and boost mechanical properties through work hardening. The machine is available in various models with drawing forces ranging from 50KN to 20000KN (approximately 5 to 2,000 tons), accommodating rod diameters from small precision bars under 10mm to large-diameter rods up to 300mm or more.
The rod drawing process begins with the raw bar---typically hot-rolled, forged, or extruded---being loaded onto the feed rack. One end of the rod is pointed (reduced in diameter) or swaged to allow it to pass freely through the drawing die. The pointed end is then gripped by the drawing carriage's clamping mechanism. The hydraulic draw carriage, driven by a powerful hydraulic cylinder, pulls the rod through the precision die. Unlike tube drawing, rod drawing does not require a mandrel or plug, as the section is solid. The hydraulic system ensures smooth, consistent force application---eliminating vibration and surging that can cause surface marks and defects. After passing through the die, the rod is straightened (often with an integrated straightening unit) and cut to length. A programmable PLC with an intuitive HMI controls the entire drawing cycle: acceleration, constant drawing speed, deceleration, and carriage return. Real-time sensors monitor force, speed, and position, making automatic micro-adjustments to maintain set parameters. The machine features a prestressed frame structure that ensures the drawing force line coincides perfectly with the rod axis, eliminating radial runout and ensuring exceptional straightness.
The machine addresses critical challenges in solid bar manufacturing: hot-rolled or forged rods often suffer from surface defects (scale, pits, decarburization), poor dimensional accuracy (out-of-round, diameter variation), inadequate straightness, and inconsistent mechanical properties across the length. Cold drawing solves these problems by:
- Removing surface defects: The drawing process shears off surface layers, eliminating decarburized zones and scale.
- Achieving tight diameter tolerances: Precision dies produce rods with diameter accuracy of ±0.02mm, reducing or eliminating subsequent machining.
- Improving straightness: The combination of drawing and subsequent straightening yields rods with straightness as high as 0.2mm/m.
- Enhancing mechanical properties: Cold working refines grain structure and increases tensile strength by 20-40%, hardness by 15-30%, and yield strength significantly, enabling the use of lower-cost base materials to achieve high-strength finished products.
- Producing superior surface finish: Surface roughness can reach Ra0.4μm or less, ideal for applications requiring minimal post-processing.
With over two decades of rod drawing expertise and thousands of drawbenches installed worldwide, FangRong has solved virtually every solid bar drawing challenge---from drawing high-tensile alloy steels for automotive fasteners to processing soft, high-conductivity copper rods for electrical applications. This deep experience is embedded in every machine we build.
1. Exceptional Rod Straightness and Roundness
The prestressed frame structure ensures the drawing force line coincides precisely with the rod axis, eliminating radial runout and producing rods with outstanding straightness and roundness (within 0.05mm). This is critical for applications where rod straightness directly impacts downstream machining and assembly.
2. High-Precision Diameter Control
Advanced hydraulic transmission and closed-loop control systems ensure rod diameter accuracy of ±0.02mm, far surpassing industry standards. This ultra-high precision reduces or eliminates the need for subsequent turning or grinding, saving material and machining costs.
3. Surface Defect Removal and Decarburization Elimination
Cold drawing shears off the outer surface layer, effectively removing scale, pits, cracks, and decarburization zones. The resulting rod surface is dense, smooth, and free from defects, ready for direct use in high-stress applications without additional surface treatment.
4. Significant Mechanical Property Enhancement
Through strain hardening, cold drawing increases tensile strength by 20-40%, hardness by 15-30%, and yield strength substantially. This allows manufacturers to use lower-cost base materials while achieving the high-strength specifications required for critical components such as bolts, shafts, and bearings.
5. Smooth, Vibration-Free Hydraulic Power
Unlike mechanical systems with fixed linkages that can cause jerking and surface defects, the hydraulic system delivers fluid, controlled force from start to finish. This eliminates chatter marks, scratches, and periodic surface imperfections---critical for rod applications where surface quality directly impacts fatigue life and corrosion resistance.
6. Wide Diameter and Material Adaptability
Capable of processing rods from small diameters under 5mm to large diameters up to 300mm or more. Handles carbon steel, alloy steel, stainless steel, aluminum, copper, brass, titanium, nickel alloys, tool steels, and specialty metals. By adjusting hydraulic pressure and speed, the machine accommodates different material hardness levels and rod specifications.
7. Integrated Straightening and Cutting Options
Our rod drawing machines can be equipped with in-line straightening units and flying shears or saws, allowing for a complete production line from raw bar to finished, straightened, cut-to-length rods in a single pass---significantly improving productivity and reducing handling.
8. Intelligent PLC & HMI Control with Quick Changeover
Programmable logic controller with intuitive touchscreen interface allows operators to program the entire drawing cycle. Quick-change die holders and rapid clamping systems minimize downtime between diameter changes, making the machine ideal for both high-volume production and job-shop flexibility.
Our Rod Hydraulic Cold Drawing Machines are available in a comprehensive range of models to suit diverse rod production requirements. The drawing force ranges from 50KN to 20000KN, with maximum stroke up to 25 meters and maximum drawing speeds reaching 30m/min. The machines feature prestressed frame type, fixed bed type, or composite type structures. The hydraulic system adopts cartridge valve integrated blocks for smooth, stepless speed adjustment across a wide range. All models can be customized according to customer specifications, including rod diameters, materials, and production volumes. For solid carbon steel bars, alloy steel rods, stainless steel rods, aluminum rods, copper rods, and specialty alloy rods alike, we offer tailored solutions to meet your specific dimensional and throughput targets.
