The WaveLine concept has been developed to transfer large stamped parts, such as body side, hood, roof and double-door units through large press tandem lines. At FAGOR ARRASATE we deliver a new top level of performance in stamping press lines, be it conventional mechanical presses or be it servo presses. Our high-speed press lines operate at high levels of efficiency and deliver output ratings that exceed conventional systems, reaching to up to 17 spm in XL-type press lines and up to 21 spm in L-type ones.
The WaveLine working mode concept allows presses to run in continuous mode, reducing the drawing and cutting speed, and reducing the occupied space in the facility, as well as clutch and break maintenance tasks. The automation follows the motion of the presses automatically, even when the line speed increases or decreases based on production demands. WaveLine installations are, in all cases, lines with short die setup times as well as powerful help on HMI for operation and maintenance tasks.
The setup of the automatization is more complex than the one in conventional press lines but once it is done the WaveLine adapts itself to the requirements of the production, optimizing the installation in a quick and versatile manner.
At FAGOR ARRASATE we can also assist our customer in the definition and design of this type of lines; for example:
The features of a High-Speed Press line are:
The cushion is one of the main areas of improvement in terms of reducing energy consumption and regenerating energy. The hydraulic cushion, a technology in which FAGOR ARRASATE is one of the market leaders, is a product with great potential of improvement in terms of energy efficiency.
Considering that servo presses have an increasing presence in the international market, we have developed a new cushion concept. This new concept, the e-cushion, replaces hydraulics with electric servo motors and uses a rack-and-pinion mechanism to transform the electric energy of the servo motor into the mechanical force required for the die drawing process. The payback time can be as short as 32 months.
This solution, of which we already have references in the market, allows us to create an ideal architecture in presses which feature servo technology in the main drive of the press and have a cushion in the bed. The energy efficiency of the press improves by up to 50% (increases the more the cushion is used) for some parts compared to its hydraulic cushion predecessor.
