PRE-TREATMENTLINE FOR PC STRAND WIRE

Inline Pre-Treatment of P.C. Strandwire with Mechanical Descaling and Electro-Phosphating.

Horizontal wire rod pay-off, the wire is subsequently driven in a combined infeeding, bending/breaking and straightening machine (BDM-2S / EG), the scale layer is broken and the wire is straightened without cracks. The wire pull in is considerably facilitated by this system concept.

In the following double-head sanding machine with two sanding belts, the wire will be cleaned and surface pre-treated for the further coating process with a cleaning level of up to 98%.
The wire preparation plant before the actual drawing process is the patented e-phos plant in line from STAKU Anlagenbau GmbH.

Production data
Inlet: ø 8.0 – 15.0 mm
HC steel with 0.82% C with tensile strength up to 1,250 N/mm²
Outlet drawing speed up to 10 m/s

Mainly:
Inlet: ø 13.0mm Outlet drawing ø 5.0 mm
Inlet speed 1.2 m/s Outlet drawing speed 8 m/s
The customer hereby achieves the same drawing speed and high quality without drawing problems as with pickled wire.
Inline electro-phosphating speed up to 1.5 m/s.

DOUBLE PAY-OFF TURNTABLE MODEL D-ADT-A/K

The double pay-off turntable is designed to pay off wire up to 2.33 m/s from low-carbon wire rod coils, whose wire diameter range ø5.5–22.0 mm and maximum coil weight of 2.5t. Total weight of machine 6.8t.

The double pay-off turntable acts as a device for drawing off the wire from the coil in a controlled manner. A gear motor turns the top rotating frame 180° forwards and backwards, in order to guarantee both pay-off turntables’ interchangeable working process. The rotating frame’s will be driven into the change position in about 30 sec. Each turntable is driven by a frequency controlled motor and can be stopped by two pneumatic brakes in an emergency stop situation. The two turntables are kept apart from each other by means of a divider. During operation, only the turntable behind the divider is ever in operation. The other turntable stands still and can be loaded. A drawing machine is required for providing the power necessary for drawing the wire. The turntable’s circumferential speed is determined by the drawing machine. The double pay-off turntable comprises a base and a rotating frame. The base is solid and permanently affixed to the foundation base. The rotating frame is affixed to the base by means of an internally bearing system. The take-up coiler are affixed to each turntable by means of 4 clamping pieces and 4 bolts.

DOUBLE-HEAD SANDER MODEL SEZ-4-300

First double-head sanding machine model SEZ-4-300 was gone into operation in a welding wire pre-treatment line with KOCH for an international major customer in Germany.

WiTechs has improved this model with the 2-roll flyer system (2-RFS), which has been proven in the SEZ-2-450 for more than two years.

It´s working with the same external dimensions and the technical data, such as max. wire entry speed of 2.4m/s with two different sanding belts.

Advantages of the 2-roll flyer system are:

  • less vibration during machine operation
  • larger loop and contact surface of the sanding belts
  • less wear of the roller bearings by the support arm
  • better sand belt tracking by increased roll dia. with 12% larger belt contact surface
  • more stable roller guidance
  • compatibility of flyers and flyer drives with SEZ-2-450
  • sanding belt dimensions of 1.440 x 300 mm (l x w)
