New header model 248 E
24 March 2015
Carlo Salvi SpA has developed a new motorised header model – 248 E – which it says is an enhanced version of the model 248 machine. The machine is complete with an electro-pneumatic clutch that allows maximum heading tonnage to be applied even when jogging.
Carlo Salvi specialises in manufacturing 2-die 4-blow machines, which can manufacture parts with complex shapes, and are able to handle wire diameters from 1.2mm to 12mm. The machines are particularly suitable for components with very large volume heads, as well as components where two dies are sufficient but at least three blows are needed, such as Allen screws or trimmed components.
A great advantage of these machines is that the third blow can very often be used as an introduction punch if parts with large heads, and a very short shank, have to be transferred.
The new machine has been specially developed in order to minimise changeover times. Its technology and speed is such that it can be run profitably for not only large volumes but also small batches.
The main features of this 248 E machine include:
• Linear wire feed, without rolls or wire-stop.
• K.O die side and punch side.
• Motorised lifting/lowering of transfer unit.
• Conveyor.
• Bad part divert.
• Transfer fingers.
The header model 248 E can be supplied with additional items, such as a quick change kit that includes: Punch block unit, transfer unit, cutter holder unit, cutter centring jig, punch centring jig, and transfer centring jig.
To handle materials such as titanium and super alloys, which can not be formed with the cold heading system, the header can be equipped with a pre-heating system.
“Customers also have the option of which heating system to install on the header model 248 E – with coil housed on the die holder or the resin bonded inductor positioned into the bedframe. In the event of special production needs, it is also possible to install both kind of inductors.”
