High-duty saws for the forging and automotive supply industries

摘要

It is becoming more and more common in forging shops that the forging lines are supplied by work stock from integrated sawing lines. The new generation of hard metal saws offered by Linsinger GmbH, Steyrermuhl, Austria, fully meets the requirements in terms of capacity, safety, availability, quality of the cutting plane and constancy of length placed on modern sawing machines.A net cutting time of four seconds for a double cut of a 90 mm diameter piece (which corresponds to a specific cutting capacity of 1060 cm~2/min) and a section cycle time of seven seconds demonstrates the high capacity of the saws during continuous operation. With 43 kW the drive power of the sawing blade is largely dimensioned. But even more important is the constant torque of the AC main spindle motor. Steels and non-ferrous metals up to 1400 N/mm~2 can be optimally cut with all available blade types. A machine base made of "Betolin", a special mineral casting prestressed in three dimensions and weighing 6000 kg, provides an excellent vibration dampening effect. The undivided sawing gear rests on linear prestressed guides and is directly driven by an AC servomotor. During the cutting process the stock is securely held by two hydraulic clamping devices. The new PC-based control enables the complete range of options for a link to modern PPS systems with order, status and maintenance dialogues. This reduces machine set-up times to only a few seconds.
