Product Details

1. Introduction

In wire and cable products, traditional conductors are mainly copper and aluminum wires, but aluminum alloy cables have gradually gained widespread application in recent years. As the first process in the manufacture of cable products, the drawing of the conductor plays a vital role and is closely related to the quality of the product. Due to its large hardness, the use of traditional sliding gear-driven wire drawing machines can easily cause wire surface damage and drawing drum wear, which will affect the surface quality of aluminum wire and reduce the life of the drawing drum.The non-sliding drawing machine provided by our company, each drawing drum is driven by the separate motor independently. During the drawing process, there is almost no sliding between the wires and the drums, which greatly reduces the surface damage of the wires and effectively guarantees the quality of the wires. This is particularly suitable for drawing aluminum alloy wires.
In addition, copper and aluminum drawing machines with individual motors can also be provided according to customer needs to meet customers' drawing requirements for different products. At the same time, we can also provide two types of single head and double head drawing machines for customers to choose, in order to meet customer demand for production capacity.

2. Equipment Features

2.1 There is basically no sliding friction between the wires and the drum surface when drawing, which can extend the service life of the dies and the drums.
2.2 Compared with the traditional gear drawing machine, it can save about 20% of electricity
2.3 When drawing large-size wires, you can turn off the unnecessary motors, this can save up to 20% of energy consumption.
2.4 The elongation of each dies can be adjusted flexibly according to production requirement.
2.5 The drums are arranged in line with quick dies change. When the wire specifications are changed, it is only necessary to replace the finished die and reduce the drawing dies, which is convenient for threading the dies and change the wire specifications.

4. Comparison of Energy Consumption

Comparison of energy consumption between our drawing machine with individual motors and a gear type drawing machine for drawing 2.6mm copper wire, as follows:



Driving method

Reduction rate

Maximum output



Individual motors


high-efficiency servo motor frequency conversion

Front 6-axis reducer + motor drive, rear toothed belt pulley + motor drive



slight slip, low noise


(2 pcs)

120T,110 degree/T

High efficiency and energy saving, low noise, large production capacity and less labor

Gear type

Host DC motor + lead DC motor

2 DC motors

500kW + 90kW


fixed reduction


180 degree/T

Large noise, high energy consumption, dies and drums are easy to wear and cannot change the reduction rate

Example: Take the peak electricity as 1.11 yuan / degree and the valley electricity as 0.3 yuan / degree: the average electricity cost is: (1.11 + 0.3) / 2 = 0.7 yuan / degree.

The production capacity of 2.6mm * 2 copper wires is calculated at 20 hours per day,it can produce 120T copper wires per day. The gear drawing machine consumes 180 degrees / T of power, and the drawing machine with individual motors consumes 110 degrees / T. The difference is 70 degrees / T.

70 degrees / T*120 T=8400 degrees (per day)*0.7 yuan (average electricity bills)=5,880 yuan (electricity bills)

5880 yuan (One-day electricity ills difference)*30 days *12 months=2,110,000 yuan (Electricity saved in one year).

The above data is for reference only!

The drawing machine with individual motors from us can not only draw copper wires and aluminum wires, but also more suitable for aluminum alloy wires. It is the first choice for drawing aluminum alloy wires.

    Main Components

    This equipment is mainly composed of the payoff device, the drawing machine, the annealing machine (only for copper RBD with individual motors), the tension controller, the take-up and traverser, and the electrical control system.

    1. The pay-off device

    The pay-off device

    The pay-off device uses a horizontal power pay-off machine. The turntable adopts gear transmission and bearing combined bearing carrier. Equipped with turbo reducer and inverter control, the pay-off speed can reach up to 100m / min, which can meet the pay-off requirements when drawing.

    2. The drawing machine

    the drawing machine

    The drawing host adopts a horizontal arrangement of drawing drums in series, and each drawing motor independently drives each drawing drum, which can realize rapid die change. By using fully immersed wire drawing box, each wire drawing die seat is provided with oil lubrication and heat dissipation, which can fully lubricate and cool the drawing wires, and improve the cooling and wire drawing effect. Because the sliding rate is reduced to a minimum, the abrasion of the drawing drum is reduced, the surface friction of the wire is reduced, thereby improving the drawing quality and increasing the service life of the drawing drum. The drawing machine frame is a steel plate welded structure. After annealing treatment, it is processed and formed after eliminating internal stress, and has high stability and strength. Due to gearless transmission, with which gear maintenance is eliminated, the equipment has small vibration and low noise during wire drawing production, and no soundproof cover is needed.

    Commercial Parts

    1. The drive system of the drawing machine is controlled by an AC servo motor made in Taiwan and a Siemens inverter;
    2. PLC adopts Siemens brand;
    3. Low-voltage electrical appliances adopt Schneider brand.

    Auxiliary Equipment

    In addition to the above-mentioned pay-off device, drawing machine, annealing device, tension controller, take-up and traverser, and electronic control system, some auxiliary equipment such as drawing dies, copper emulsion filters, aluminum powder centrifugal separator pointing machines and cold welders are also needed during the drawing process.

    The drawing auxiliary equipment we provid can meet the drawing production of different types of copper, aluminum / aluminum alloy RBD with individual drivers. It can not only ensure the smooth drawing process, improve the surface quality of the product, but also reduce the loss of drawing equipment and increase its service life which is an essential equipment during the drawing process.

    Installation and Commissioning

    Before the equipment arrives at the customer’s factory, the customer needs to dig the pools for oil cooling and filter system according to the drawings we provide; after the equipment arrives, the customer needs to install the equipment according to the drawings, fix them with anchor bolts, and then connect the pipes. After that, we will send an experienced mechatronics engineer to guide installation and commissioning. After the equipment is installed and commissioned, the engineer will carry out no-load and full-load test machines, and train customers’ workers. The entire commissioning time is expected to be two weeks.
