Tamping machine - Type SE 7V

This machine is used for fixing copper cables into carbon brushes by tamping. It is the succession type of our Tamping Machine Type SE 5.

 

Design:


Machine body of aluminium profiles. Attached electric switch box with a programmable processor. Attached pneumatic switch box with solenoid valves. Compressed air maintenance unit. Moveable table running on ball sleeves. Two table lifting cylinders. Oil brake cylinder for slow movement of the last 10 mm of stroke. Full digital precision tamping frequency (9 steps ) by means of a fast switching valve. The force of impacts is determined by tension springs, which can be exchanged quickly.


Dependant on use three types of tamping heads are available:

- Standard type tamping head for chopper cables 0.5-6.5mm diameter
- Soft tamping head for chopper cables 0.3-3.4 mm diameter
- Ultra light tamping head for chopper cables 0.3-2.4mm diameter


Two hand safety switch for the set up of the machine. Short set up time and therefore also suitable for short run production. 

 

Method of operation:

After the set up of the machine the drilled carbon brush has to be placed manually in a pneumatic valve and the tamping cycle has to be started by means of the pedal switch. The brush will be clamped – the scissors moves to its back position – the table moves to its top position and made a knot itself at the end of the copper cable at the bottom of the drill hole. The clamping cylinder opens and the tamping starts. Tamping powder is now inserted uniformly on top of the knot. Between the drill hole wall and the copper cable and tamped firm to the set level in drill hole. The tamping powder quantity for stroke is adjustable. After reaching the tamping level the tamping stops and the table descents to its start position. The copper cable get clamped and the scissors cut the copper cable to the required length. Simultaneously with the scissor the pneumatic vice opens and the finished carbon brush can be taken. For each copper cable diameter you need 1 clamp, 1 tubular ram, 1 bottom plate.

Application:

For processing tamping contacts on carbon brushes and cutting the copper cable to the required length.
