SAS Drawing Lines

SAS Engineering and Planning designs and realizes coil-to-bar, coil-to-coil and bar-to-bar Combined Drawing Lines for ferrous and non- ferrous materials and also supplies innovative solutions in the cold finishing of bars and rolled equipments.

Coil to Bar

The coil-to-bar Combined Drawing Lines are composed as follows:
 

1. Pay-off
2. Robot
3. Pre-straightener
4. Pulling unit
5. Shape-straightener
6. Shear
7. Two-roll straigntener
8. Chamfering machine
9. Strapping, weighing and storage
   
    

Bar to Bar

The coil-to-bar Combined Drawing Lines are composed as follows:
 

1. Loading table
2. Introducer
3. Pulling unit
4. Shape-straightener
5. Shear
6. Two-roll straigntener
7. Chamfering machine
8. Strapping, weighing and storage

Descriptions of the components forming the drawing lines:

1. Pay-off
   Designed to minimize the gap between the end of the drawing of a coil and the beginning of the drawing of the next one.
   They are equipped of a platform that can rotate of 360°, operated by an hydraulic gear motor.
2. Robot
   The robot has a manipulator which is a kind of extension of the operator's hand, who, could not otherwise handle material's tip when materials have rather thick sections.
3. Pre-straightener
   These machines take the material from the pay-off to the die through mecanical descaling units (or others).
   They are composed by two groups.
4. Pulling unit
   The experience gained over many years in the field allowed SAS to place itself on the market with a system which incorporates all the new technics, available nowadays, with the utmost reliability.
5. Shape-straightener
   The bar straightening process is obtained by the passage of the bar through a pre-setted roller set. The two straighening heads, vertical and horizontal axis, allow to process the two bar axis.
6. Shear
   The market is evolving and it is always in search for production lines with higher and higher speed. SAS answer these requests offering lines with an increased speed, an increase in the speed of the drawing lines, of the cutting quality obtained and of the tolerance of the length.
   Flying Shears cutting “bushing-to-bushing” have been designed and realized.
7. Two-roll straigntener
   The SAS two-roll burnishers have a very strong frame, they are designed to straighten ferrous and non-ferrous materials round bars. Thanks to the simplicity of the execution, they are a precious support both in-line in connection with drawing bench or peeling machine and out-line.
8. Chamfering machine
   The chamfering machine is composed by a fixed head and a moving head.
   Each head had two spindles and each head can reach a production of 30 bars every minute, maximum with chamfer up to o,5 cm.
