Straight Line Wire Drawing Machine

What Is a Straight Line Wire Drawing Machine?

RKM straight line wire drawing machine is designed for continuous drawing of steel wire rod through multiple independently driven drawing blocks. The machine can reduce 6.5 mm wire rod to the required finished wire diameter through continuous drawing passes and is widely used for producing wire for welded mesh, nails and other steel wire products.

This wire drawing machine is more productive due to its higher drawing speed and better cooling system. Its easy operation and faster threading save labor costs. High-pressure narrow-gap internal water cooling makes the machine run better, allowing for high-efficiency wire cooling.

Applicable to high/middle/low carbon steel wire, stainless steel wire, etc.

How Does a Straight Line Wire Drawing Machine Work？

Pneumatic top-drawing pay-off stand–Peeling System–Straight line wire drawing machine–Trunk take-up machine

Annealing furnace

When the wire is hard and brittle, it is easy to break or have surface defects during the drawing process. Through annealing, the metal’s hardness is reduced, the ductility and plasticity are improved, the drawing performance of the metal wire is optimized and the quality of the final product is improved.

Main functions:

Eliminate internal stress of metal materials.
Soften metal to facilitate subsequent drawing.
Adjust metal microstructure and optimize wire properties.
As part of the heat treatment process, it is used to improve the quality of drawn wire.

Payoff/Supply Unit

Closed-type shelling machine

The closed-type shelling machine is welded by steel and iron plate, with a shelling wheel inside. 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 broken. It falls into the oxide scale collector.
Features:

Closed structure, environmental protection
Safety protection, ensuring the safety of operators
Can accurately control the shelling depth without damaging the wire

Wire Drawing Production Line

The wire feed device feeds the metal wire into the drawing system.
The metal wire is deformed by force in the drawing system, reducing the cross-sectional size and increasing the length.
The drawing system consists of 1-12 blocks. The number of blocks is determined according to the size of the customer’s wire diameter, and the metal wire is gradually drawn to the required diameter.
The RKM straight line wire drawing machine is equipped with a protective cover and lighting above, which is energy-saving and environmentally friendly and enhances the brightness of the field of vision.

Lubrication System

RKM straight line wire drawing machine uses a patented rotating die cooling system. Rotating die loading is done from the top in a very simple and time-saving way.
The rotating box is equipped with a key to easily open the die box.
One is drawing the powder lubrication zone, the other is drawing the die water cooling zone.
Advantages of Rotating die: achieve the highest drawing performance and output, better lubrication and wire calibration, prevent wire ovalization, energy saving, higher productivity, higher wire quality after drawing.

How to Choose the Number of Drawing Blocks for a Straight Line Wire Drawing Machine?

Based on actual RKM wire drawing machine configurations, the following examples show how different input and output wire diameters affect the required number of drawing blocks:

Input Wire Diameter	Output Wire Diameter	Wire Material	Number of Drawing Blocks
5.5 mm	2.5 mm	Low Carbon Steel	6 Blocks
6.5 mm	3.3 mm	Low Carbon Steel	6 Blocks
7.3 mm	1.8 mm	Low Carbon Steel	11 Blocks
8.0 mm	1.4 mm	Low Carbon Steel	12 Blocks

Example: 6-Block Wire Drawing Process

For example, when drawing 5.5 mm low-carbon steel wire down to 2.5 mm, RKM uses a 6-block configuration with progressive diameter reduction:

5.5 mm → 4.8 mm → 4.2 mm → 3.6 mm → 3.2 mm → 2.8 mm → 2.5 mm

Each drawing block reduces the wire diameter progressively rather than reducing the wire directly from the inlet diameter to the final diameter in a single pass.

How Do We Determine the Correct Configuration?

The number of blocks should not be selected only according to the input and output wire diameters. RKM engineers also consider the wire material, tensile strength, reduction per pass, drawing speed, die configuration, cooling and lubrication conditions before determining the final machine configuration.

FAQ

What is a straight line wire drawing machine?

The straight-line wire drawing machine is a device that reduces the diameter of metal wires by continuous drawing.

How does a straight line wire drawing machine work?

The wire rod first passes through surface preparation and then enters the first drawing die. Each drawing block pulls the wire through a die to progressively reduce its diameter. The wire then continues through multiple blocks until it reaches the required final size. For example, a 6-block drawing process can reduce 5.5 mm wire progressively through 5.5 → 4.8 → 4.2 → 3.6 → 3.2 → 2.8 → 2.5 mm.

What is the difference between a straight line and pulley wire drawing machine?

A straight line wire drawing machine uses multiple drawing blocks arranged in a straight production line with coordinated drive and control systems, making it suitable for continuous production where stable speed and higher productivity are required.

A pulley wire drawing machine uses a different transmission and wire accumulation structure and is often selected according to production capacity, wire specifications and investment requirements.

RKM can recommend the appropriate machine type based on your raw material and finished wire requirements.

What input and output wire diameters can a straight line wire drawing machine process?

The available input and output diameter range depends on the machine model, number of drawing blocks, wire material and die configuration. For example, RKM straight line wire drawing machine configurations can be designed for applications such as 6.5 mm to 3.3 mm, 7.3 mm to 1.8 mm and 8.0 mm to 1.4 mm. Different wire specifications require different drawing passes and machine configurations.

How many drawing blocks do I need?

The required number of drawing blocks mainly depends on the input diameter, required output diameter, wire material, allowable reduction per pass and production requirements. For example, an RKM configuration uses 6 blocks for 6.5 mm to 3.3 mm, 11 blocks for 7.3 mm to 1.8 mm, and 12 blocks for 8.0 mm to 1.4 mm. The final number of blocks should be determined according to the complete drawing process rather than the input and output diameters alone.

What is the production speed of a straight line wire drawing machine?

Max.20m/second

Can a straight line wire drawing machine process high-carbon steel wire?

Yes, a straight line wire drawing machine can be configured for different steel wire materials, including low-carbon and certain high-carbon steel wire applications.

How much does a straight line wire drawing machine cost?

The price of a straight line wire drawing machine depends on the input and output wire diameters, number of drawing blocks, motor power, production speed, control system, automation level and auxiliary equipment

What information is required to select the right wire drawing machine?

To recommend the correct machine, please provide your input wire diameter, required output wire diameter, wire material or tensile strength, required production capacity and finished wire application. RKM engineers will calculate the drawing passes, recommend the appropriate number of blocks and prepare a suitable straight line wire drawing machine configuration for your project.
