Our hydraulic bench will help to get qualified extruded product with high level surface and straightness. All section fo flat shape ,rod shape,tube shape,and abnormal shpe of aluminium,copper profile can be drawed by our hydraulic drawing machine.
Production process
1. After the pay-off table containing bar coil from conform extrusion is shifted to the front of draw bench, the pay-off table will release bar to the draw bench for drawing.
2 .After pointing, the bar will be pulled out and fed into the straightening unit before the bar is guided into die for drawing. The protruding length of bar out of the die shall be controlled at 200mm in minimum. However, the pointing machine (rolling mill) is excluded from the scope of supply.
3. The draw bench is equipped with auto-feeding device. The pay–off operation of every bar coil only needs to be done one time at the initial period. After the achievement of pay-off, the clutch must be relived. Otherwise, the accident might be occurred since the straightening unit is a kind of passive drive.
4. After straightening, the bar will go through the zone of oil cooling and lubrication, then go into the die to be drawn. The die shall be made precisely in order to get qualified finish product.
5. The drawing jaw is driven by the main long cylinder, which can achieve fast return under the assistance of four rollers amounting on the bed. The fast return can save a lot of time and improve the efficiency of the production. The action of clamping is achieved by air cylinder, via crank gear mechanism, which will relief the bar automatically before return.
6. When the bar is drawn to the position, PLC will emit the instruction to relief the main cylinder, and drive the saw to cut the end of bar before the shifting car reach the position. After cutting, the certain length of bar will be kept for the next drawing procedure, and then the air cylinder is then relieved.
7. The function of shifting device is to receive the drawn bar after cutting and transfer the bar to the conveyor. This shifting device will be totally automatically following up the movement of the drawing jaw, preventing the bar from dropping off.
8. The function conveyor if to transfer the bars to the finish product table where can achieve length sizing.
