Antishcnc Machinery recently received a customer requirement for drawing 2.0-2.2mm low-carbon steel busbar into fine 0.75-1.0mm finished wire.
So we provides a highly efficient and continuous production line, which is broken down as follows:
Process design ideas and processes
Φ2.0-2.2mm busbar→ Upper-drawing unwinding machine
→ LZ9/350 straight-in wire drawing machine (finished wire diameter Φ0.75-1.0mm)
→ SG-500 Spool winder or End hook steel fiber machine
Production line equipment
1. Upper-drawing unwinding machine
The pay-off rack occupies a small area. During the pay-off process, the pull rod will rotate along with the direction of the wire, so that the wire is not easily tangled during high-speed pay-off. It is also equipped with a tangled wire safety stop switch, which is also very convenient to operate.
2. LZ10/350 Straight-in wire drawing machine
| Device Model | LZ10/350 straight wire drawing machine |
| Roll diameter | Φ 350mm |
| Drawing pass | 10 |
| Inlet diameter | Φ2.2 mm |
| Finished wire diameter | Φ 0.75-1.0 mm |
| Incoming line strength | ≤ 13 00mpa |
| Maximum line speed approx. | 1100 m/min |
| Total compression ratio | 88.38 % |
| Average pass compression ratio | 19.36 % |
| Motor power | The 1st to 10th units all use 15kw variable frequency motors |
| Mold size | Φ40mm × 25 |
| Roll layout | The reel is vertical and tilted |
| Line direction | From left to right |
| Pay-off method | Paying off the wire through the upper draw-out pay-off stand |
| Reeling method | Spool take-up machine |
| Wire pressing device | Each reel is equipped with a wire pressing device to prevent the wire from slipping off the reel when the wire is broken or stopped. This reduces the workload of employees and improves work efficiency, making the operation of the entire wire drawing machine more convenient and the automation performance more superior. |
| Disconnection and shutdown | Each unit has a disconnection shutdown function |
| Guide wheel, tic-tac-toe roller | The rotating parts in contact with the wire (such as the well roller, etc.) are sprayed with tungsten carbide, HRC63 |
| Wire drawing die box | ( 1 ) The die box consists of a powder box and a water cooling unit. ( 2 ) The 1st to 10th die boxes use an automatic rotating stirring die box. The use of a rotating stirring die box can ensure that the lubricating powder is evenly applied to the surface of the wire during the drawing process, thereby improving the lubrication effect, reducing the loss of the wire drawing die and improving the quality of the wire surface. Automatic stirring of the lubricating powder can reduce the workload of the operator and avoid safety hazards when manually stirring the lubricating powder. ( 3 ) The wire drawing die in the die box uses an immersion circulating water cooling unit. |
| Wire drawing reel | Diameter Φ 350mm . ( 1 ) Roll material: cast steel ZG45, surface surfacing 4.5mm and then sprayed with tungsten carbide 0.5mm , hardness HRC63 . Surface roughness is less than 0.8umm . ( 2 ) The inside of the roll is treated with zinc-lithium alloy for corrosion protection |
| Roll cooling | ( 1 ) Internal cooling of the reel: Three water pipes are used to spray water on the inner wall of the reel at 120 degrees. The water is sprayed to all parts of the reel through the blade-type water ring for full-range cooling.
( 2 ) External cooling of the reel: The ventilation pipe under the outside of the reel uses 360 -degree direction to force air cooling on the reel surface and wire, so that the reel surface is kept at a normal temperature |
