HFT - Hight quality press-brakes with patented "Reactive Bottom Beam"
The HFT press-brakes are equipped with the AMADA's patented lower beam as standard, giving "Parallel Deflection" under all bending loads. This concept ensures consistent punch penetration into the vee die, over the full bending length under all loads and conditions.
Renowned and unique concept for parallel beam deflection
The bottom beam is composed of a centre plate "A", supporting the worktable "E". The centre plate is mounted between two fixed sideplates "B" which are in turn welded to the side frames. The middleplate "A" is supported by two large steel shafts "C", located either side of the central axis. During bending, the reactive forces deform the centre plate in parallel with the upper beam. Consequently, the deflections, small but unavoidable, of the two beams, are of the same value, thereby ensuring that the punch penetration in the vee die remains consistent through out it's length, guaranteeing accurate bending.
The HFT machines in the lower tonnage range (up to 100 tonnes) have Amada's new patented "Reactive Bottom Beam". The designand construction of the bottom beam is the result of extensive research to obtain the optimum parallel deflection of the beams.
Safety on Amada press-brakes:
Operator safety first, has always been AMADA's motto the HFT is no exception. All HFT press-brakes are built, type tested and certified to comply with current CE regulations. A 3-position footswitch is a standard feature on HFT press-brakes. Depending on the customers requirement, AMADA can supply different safety solutions to suit their needs including two-hand push button control, light guard control unitor protective laser beam.
Easy Hands On Controller (CD 2000)
CD 2000 is a real innovation in the field of numerical Press Brake controls. The new micro-processor CNC is user friendly, functional and offers total control over the bending. It's' simplicity of use, fast processing time and easy interface make it very popular among users. The CD 2000 incorporates two operating modes as standard. This allows the operator to manually move the upper beam (Y1 and / or Y2) and backgauge axes individually or program the press brake using direct angle input.
Ergonomically designed exclusively for AMADA the hand held CD 2000 control allows quick and simple partprogramming by the operator. Robust and equipped with a LCD screen protector, it is very well suited to a production environnement.
The magnetic base allows the operator to easily position the controller any where along the press brake forhigh production demands .
HFT press brakes are equipped with quick release punch holders on adjustable sectionalised distance pieces. This versatile system provides very simple and rapid tool change for any part type. Individual punchholders can be moved as needed. By using 100 mm extended distance pieces, deep box bending can be performed without the need for any special or expensive tooling. They also allow window and horn applications to be carried out in the centre of the machine. In the event of excessive loading, the distance pieces also protect the upper beam from damage.
The ultimate step in achieving accuracy
Bend accuracy is highly dependent upon the backgauge. Two, independent axes (X, R,) are driven by large recirculating ball screws. The high performance backgauge rail has been exclusively designed for AMADA and is made of an extruded aluminium alloy. The use of this technology allows a extremely light but strong and rigid moving element, giving maximum speed and maintaining long-term accuracy. The standard, multi position fingers, provide sheet-gauging capacity up to 1020 mm. The 250 mm backgauge height stroke give the ultimate versatility for the user. This new backgauge permits the use of extra backgauge fingers formulti-stage bending operations.
The AMADA Digipro is a patented digital protractor, linked to the CD 2000 numerical control. This highly reliable precise measuring device ensures accurate measurement of the bent angle. By Simply pressing the function button, it transmits the measured angle value to the CD 2000 numerical control, which then recalculates the punch penetration to give a perfect angle.
Bending precision, an assurance to quality
The bending accuracy is directly related to minor stresses and deformations in the upper and lower beams. Under load, the beams on a conventional press brake deflect in opposite directions. A minor variation of punch penetration into the vee die will lead to considerable variation of the bend angle. Perfect control of straightness, parallelism and rigidity of the beams are key factors in achieving accurate bends.
