The different types of steel wire drawing machines and their technology

• Straight line wire drawing machine

The straight-line wire drawing machine is one of the dry wire drawing machines. It treats the metal wire more gently and provides better wire cooling during the drawing process, so the wire quality is greatly improved. RKM’s professionally designed straight-line wire drawing machine is ergonomic and efficient and uses a patented cooling system to ensure perfect and controlled heat exchange and wire cooling of the entire module to achieve the best drawing effect.

Straight line wire drawing production line:

Pneumatic top-drawing pay-off stand – closed shelling machine – DPZ8/560 CNC vertical straight wire drawing machine – elephant trunk wire take-up machine (or hydraulic I-wheel wire take-up machine).

The pneumatic top-drawing pay-off frame adopts a cylinder lifting device with a height of 4.5 meters, which is used to protect the wire feeding from being stable and smooth without messing up the wire; the wire is guided by the swing arm and several guide wheels and acts on the tension Next, it enters the subsequent wire drawing machine for drawing; the pay-off frame carries the weight of the wire rod ≤ 2.5T.

The closed shelling machine is made of welded steel and iron plates. The shelling wheel is made of alloy material. After the low carbon wire passes through the shelling wheel, the oxide scale on the surface of the low carbon wire is loose and fragmented, which can better pull out the wire.

The straight-line wire drawing machine consists of 12 blocks, each block size is Φ560mm, the surface is sprayed with supersonic tungsten carbide, the spray thickness is 500μm (0.5mm), the functions of spraying tungsten carbide coating: 1. Reduce the friction coefficient and reduce wear, bite, etc. 2. The appearance of the object can reach 99% lubrication. 3. The friction coefficient can be reduced to 0.06-0.06, making the parts more wear-resistant.

The surface of the block is made of ZG45 cast steel and has been treated with spray welding and wear resistance. The surface roughness is ≤ Ra0.8 and the hardness is HRC ≤ 50. The service life is guaranteed to be no less than 22,000 hours/three years. The inside of the drum is sprayed with anti-corrosion coating to prevent scaling. ; The interior adopts narrow gap water cooling; the exterior adopts strong wind cooling, and the cooling effect is remarkable.

All incoming wire mold boxes use rotating mold boxes to prevent the finished wire from becoming elliptical and increase the roundness of the wire. The rotating mold adopts an exclusive patented system for direct water cooling. The mold is divided into two working chambers: a cooling water chamber and a lubricating powder chamber. It has an independent cooling water supply. It adopts a low water pressure and large flow design, which has no obvious impact on the waterway pressure drop and a stable cooling effect. The application of the rotating mold ensures the following advantages: Achieve the highest wire drawing performance and yield, no tunneling, better lubrication and wire alignment, no wire ovalization and longer die life, energy saving, higher productivity, and better-finished wire quality.

Each block of the fully automatic wire drawing machine can be run separately, or the whole machine can be run in conjunction. After the whole machine is started, the equipment runs at a low speed. After the speed is increased, the equipment runs at a given speed. The linked running speed of the whole machine is set by the PLC touchscreen. Individual operating speeds can be set internally. Braking time: normal stop: ≤30S, quick stop: ≤10S, emergency stop: ≤5S, the whole machine realizes single action, inching, linkage, continuous proportional operation of the designated machine head, and proportion setting. The whole machine is in normal stop, Quick shutdown, emergency stop, and full line startup without interruption.

The characteristics of the continuous wire drawing machine include continuous production and continuous wire drawing processing, which improves production efficiency and reduces production costs. Through precise control systems and optimized process flows, high-precision wire processing can be achieved to ensure product quality. It can be applied to wire processing of different materials and different cross-sectional shapes and has strong versatility and flexibility. The whole machine adopts an integrated design, with a compact structure, small footprint, and easy operation. Equipped with an advanced automated control system, it is easy to operate and can realize intelligent production. Use advanced refrigeration and lubrication systems to reduce energy consumption and environmental pollution.

Straight-line wire drawing machines process materials quickly and efficiently, reducing manufacturing time. Advanced control systems ensure that wire is drawn to precise tolerances and specifications, resulting in reliable, high-quality wire. Modern wire drawing machines often include fully automated user interfaces, making them easy to use and maintain. Low maintenance, most wire drawing machines are durable, have strong components, and require little to no maintenance. The machine has high working efficiency. The wire wheel is precision manufactured with imported materials, and the wheel surface is carburized to improve wear resistance. The whole machine is equipped with an automatic cooling system and can automatically shut down after the work is completed.

The elephant trunk-type take-up machine uses a 550-type reel take-up tank, and the surface of the reel is treated with tungsten carbide. Its advantages include no noise, high transmission efficiency, strong overload capacity, and easy maintenance. The maximum take-up weight can be changed according to customer requirements. The belt transmission parts and the take-up I-wheel plate on the take-up machine are equipped with protective covers to ensure personnel safety.

The hydraulic I-wheel take-up machine consists of a base, an automatic wire arrangement device, a transmission system, a hydraulic expansion and contraction I-wheel, a loading and unloading trolley, etc. It is used for winding steel wire and loading and unloading I-wheels. The take-up winding motor and frequency converter comprehensively control automatic constant tension. The braking method is pneumatic braking.

Types of drawable metal wires: high carbon wire, low carbon wire, medium carbon wire, stainless steel wire, GI wire, SS wire, alloy steel wire, zinc wire, zinc alloys wire, steel rebar wire, ribbed wire, Zinc-Aluminim Coated wire, iron wire, etc.
