Twin Chain Three Line Automatic Cold Drawing Machine for Aluminum Stainless Steel pipe and bar
I. Advantages of Twin chain three line automatic cold drawing machines
1. Drawing car and main drive chain are fixed setting, this structure avoid loud noise from chain hit the bed body.
2.Main chain to-and-fro movement, when the car drawings pipe, the main transmission system co-rotation; when the car returning, the main motor zero velocity on standby, it reduces motor idle running time and save energy.
3. The center height of die and transmission almost at the same level, it reduces the tremble phenomenon of main chain when it moving and has advantage of improve drawing stability.
4. Adopts bowl spherical mould sleeve, different die can be adjusted separately, convenient to adjust straightness of each work piece at time of multi drawing.
5. The main gear reducer is hardened reducer; it rotates smooth and low noise.
6. The bed body is half closed; main chain and drawing car move inside, this structure is more beauty and safety.
7. Realize mechanization and automation, and reduce labor intensity.
8. Reasonable discharging method and avoid scratching work piece effectively.
9. Equipped with chain elastic tensioning device, chain break detection, and limit mandatory parking etc. safety protection devices.
10. Electric control system has friendly interface, the data of drawing force, working speed, work piece length etc. is shown in it.

III. Cold Drawing Process
Prepare raw material – Acid pickling, lubrication – Cold drawing – Heat treatment –Finishing – Inspection – Finished product storage
Acid pickling, lubrication – Cold drawing – Heat treatment (those three steps should be repeated in according to size of raw material and finished product, required precision and property etc.)
