Application:

We developed VT-12B solder roll machine with reference to the international advanced technology in this field. It’s mainly apply to the rolling of lead-free tin solder wire, tin and zinc alloy solder wire, zinc & aluminum alloy solder wire.

Machine structure:

VT-12B roll machine is make up of wire take-up shaft, wire adjusting device, rolling device, pay-off device, cooling & lubricating system, drive system and electric control system.

Electric control:

Controlled by inverter, can change speed according to different wire diameters.

Finished wire diameter: Can make per customer’s requirement. Our standard specs are: Ф16mm~Ф6.4m,Ф14mm~Ф5.8mm,Ф12mm~Ф5mm, Ф9.0mm~Ф3.7mm.

Advantages: Compared with the traditional drawing machine, it has the advantage of low noise, low energy consumption, high output, and good tactility for the coming drawing.

1)Low noise

The noise of the traditional drawing machine comes from the shaking wire clash the dies and roller. This is due to the corresponding slide of the wire and roller. The wire will be easily broken if without this kind of slide. So this is an inevitable disadvantage of the drawing machine. While roll machine can well solved this problem and make lower noise.

2)Low Energy consumption

There’s four ways of energy consumption for the wire drawing machine: a) Wire getting smaller and smaller and give heat by distortion; b) Wire clash the roller and give heat by attrition; c) Wire pass through the dies and give heat by distortion; d) Wire pass through the dies and give heat by attrition. While roll machine have two ways of energy consumption: a) Wire give heat by rolling distortion (This is not inevitable energy consumption); b) Wire give heat by rolling attrition. This kind of heat giving should smaller than wire pass through dies as the roll machine was rolling attrition while the wire drawing machine is sliding attrition.

3)High Output

With the above-mentioned advantages, roll machine have a higher output. The relative specs output list as below:

         Ф16mm~Ф6.4mm      7.5T/10hr

Ф14mm~Ф5.8mm      4.5T/10hr

Ф12mm~Ф5mm      3.7T/10hr

Ф9mm~Ф3.7mm       2.3T/10hr

4)Good tactility for the coming drawing

The alloy will get more compact after rolling so it can enhance the tactility. b) Big size wire pass by roller can be easily being one-side drawn; some can even find side cracks. Roll machine adopt straight line in-put will well solve this problem.

6,Roll machine disadvantage:

Though roll machine compared with traditional wire drawing machine has many advantages, but it also has it’s own shortage. As the two roller can not be perfect match each other, so the wire brightness & roundness comes out from the roller can not be that good as wire drawing machine. So the final product has to be finished by the wiredrawing machine.
