The equipment is mainly composed of pay-off device, drawing machine, annealing device, tension controller, take-up and traverser, and electronic control system.

1. Pay-off

The pay-off of the multiwire drawing machine is a rack type in which the number of pay-off can be matched according to the number of wires. The pay-off speed can reach up to 250m/min, which can meet the pay-off requirements of multiwire drawing machine at high speed.

2. Wire Drawing Machine

The drawing machine controls 8 wires as a basic unit, 16 wires as a double-layer arrangement, or control 7 wires as a basic unit, 14 wires as a double-layer arrangement. The drawing dies are designed in a tandem horizontal arrangement. The mechanical transmission adopts gear transmission and dual electric drives (the main motor and the fixed speed motor are driven separately). This can realize quick change of dies and greatly reduce the auxiliary time during changing.
The base of the drawing machine is a welded structure, which is processed and formed after annealing and eliminating the internal stress with higher stability and strength. The gear box body is divided into two sections, and processed and formed after annealing and eliminating the internal stress. It uses high-precision helical gear transmission and is equipped with spray-type strong oil cooling and lubrication. With pressure protection, it can realize lubrication failure shutdown, and is equipped with lubrication cooling and filtering device. The cooling box adopts strong spray type lubrication cooling, which can fully cool and lubricate the drawing wheels, dies and wires, so as to ensure better drawing quality. The spray is pumped out by motor pressure, sprayed with the eye mold base horizontal spray drawing wheel. The eye mold base is designed with oblique holes to align the center of the dies, which can effectively clean dies’ center and reduce the loss. The box cover adopts flip structure, which is easy to operate.

3. Annealing Machine

Our annealing machine adopts the contact short-circuit annealing and has novel structure design. You can choose two-stage annealing or three-stage annealing according to the requirement of wire diameter. The body adopts horizontal welding structure with recovery tank for coolant at the bottom. The conductive wheel set uses the combined structure with copper wheel body and nickel spraying conductive roller. The carbon brush and conductive wheel are concentrated cooled by using powerful fan. Each conductive wheel is driven by a flat belt, and the power is provided by the fixed-speed wheel motor. The annealing power supply is direct current, which is suitable for simultaneous annealing of several copper wires.
The annealing machine is composed of conductive system, oxidation protection system, cooling system, drying system and electrical system. The oxidation protection uses steam protection; the cooling and lubrication uses dilute concentration drawing liquid circulation; the drying system uses compressed air and die drying. It can ensure the appearance of the copper wire is bright and no oxidation, and can also meet the performance requirements of the elongation and resistivity of the copper wire after annealing.

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, 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 multiwire drawing machines. 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.

About the multiwire drawing machine, we have many drawings to help customers, including layout drawing, foundation drawing, drawing for annealing liquid pool, schematic diagram of pipeline, and emulsion pool drawing. Customers can build plant according to the layout, and plan the depth of the foundation and prepare the anti-settling pile if the ground is not hard enough to support the equipment according to the foundation drawing. Customer can build the annealing liquid pool according to the reference drawing we provided, but also need consider the actual situation of the plant. This is also suitable to the emulsion pool.

We will send engineers to guide the installation and commissioning after the equipment arrived. The engineer will help to install the equipment, then try to drawing with different dies. During the drawing process, the engineer will train the customer’s workers, teach them to tread the wires through the drawing dies, and deal with the problems encountered in the drawing process. The entire process probably will take 10 days.

Q: Can I visit your factory?

A: All the customers from both home and abroad are warmly welcomed to visit our company and factory.

Q: Do you supply the installation and commissioning?
A: Yes, we do as followings:
-As soon as customer informed us the machines are put in the right place, we will send both mechanical and electrical engineer for machine start up.
-No-load testing: After machine installed completely, we make no-load testing first.
-With-load testing: Usually we will can produce 3 different wires to make load testing.

-Acceptance report: After the buyer confirms that machine can reach all specification under contract, the acceptance report will be signed for our record that machine will be in guarantee period.

Q: What information should I offer to get a detailed quotation from you?
A: For single machine: Usually we need to know inlet wire size, outlet wire size to be produced, productivity, pay off and take up size to choose the right machine.
For new cable plant or new cable production line, we need to know the datasheet of cables to be produced, the productivity, the standards to be followed, etc to design all machines needed.

Q: Can you supply the auxiliary equipment along with the machines?
A: Yes, definitely.
We has supplied heat exchanger, copper/aluminum powder filter machine, cooling tower, chiller, air compressor, drawing dies, pointing machine, cold welders, bobbins etc. with our machines.

Q: Could you do the design for the whole plant?
A: Yes, this is our advantage.
With the data sheet of cable to be produced, the standard your cables should follows, the productivity you expected. Our engineer on production technology and machinery will make design of production machines, test equipment, accessories like bobbins, dies, rewinding lines and materials needed.

Q: How can I know the status of my order?
A: We have our OA system on tracking the production.
For any of your request we can send photos and videos of your order, also we can use FACETIME to let you know the production.

Q: How do you work on the inspection before delivery?
A: We will make dynamic balance testing, levelness testing, noise testing, etc. during production.
After production finished, usually we make no-load running of each machine before delivery. Customers are welcomed to attend the inspection.

Q: What exhibitions will you attend, can we meet in the fair?
A: Dusseldorf International Wire and Cable Fair;
Wire South America Fair;
International Wire and Cable Fair in Shanghai;
