Long and heavy profiles bent automatically

Shear-Form Machine Tools product story

Two double bending machines for the building cladding industry work long and heavy profiles, undertaking positive and negative bends using two bending cheeks in one operation.
Information regarding two new double bending machines 'TwinMatic' and 'TwinBend' for the building cladding industry from Swiss company Jorns AG, is available from their sole agent in the UK, Shear-Form Machine Tools, the Coventry based sheet metal and plate working machinery supplier.
Double bending of long and heavy profiles has been developed by Jorns allowing these two new machines to undertake both positive and negative bends using two bending cheeks in one operation.
Whereas more than one operator is normally required to reverse or turn long profiles, TwinMatic and TwinBend require one operator making high precision profiling operations faster and also safer.
The fully automatic TwinMatic and the semi-automatic TwinBend are available in different sizes to produce profiles in lengths of 4m, 6,4m 8, 10 and 12.2m.
They are able to process sheet steel up to 3mm (400N/mm2) thick.
The clamping finger on the TwinMatic is able to produce a minimum 15mm leg height with a traversing path of 15 - 1150mm.
The gripping finger can grip bent sheet with a leg height up to 40mm.
On TwinBend the traversing path is 12mm - 1150mm.
Both machines operate at speeds up to 250mm/sec.
Both models are controlled using a Touchscreen TFT colour display with CNC 2000 software operating in a Windows environment, which allows the operator to store his profile parameters for withdrawal at any time.
The operator can programme the 7 CNC axes - upper cheek, upper and lower bending cheek, upper and lower bending cheek displacement, radius adjustment and stop.
It also has the latest CAN-bus technology.
A feature of both models is the unique programmable air gap which is automatically adjusted to the sheet material thickness depending on the configuration of the profile using both the upper and lower bending cheek.
Both models are able to handle painted surface without causing surface cracking or damage to the profile.
TwinMatic is fed automatically with clamping fingers, which also function as a normal backstop, whilst the TwinBend is fed manually.
The TwinMatic is supplied with a 3-sided mesh fence enclosure and a light guard as standard, whilst the TwinBend includes an emergency stop bar over the full length of the machine.
