GSW FeederStraighteners, series VRMA are just as simply operated as our Straighteners of the RMA series. With servo drive and length measuring system they offer the additional functionality of material feeding (positioning) over just straightening. Their most common application is cuttolength and spacesaving coil feeding. The already revolutionary alligatorhead can be extended with hydraulic opening for full piloting when feeding into stamping presses with progressive dies. For especially heavygauge materials or high demands in flatness, our VRMZ series FeederStraighteners are the correct answer. They process crosssections as large as 2000 x 5,0 mm. up to 2000 mm material width and 16 mm thickness max crosssection approx.. 2000 x 5 mm or 650 x 10 mm max net output approx. 50 – 150 m/min max cycles with piloting approx.. 40 – 100 SPM

Our AZP 11-roller straightener servo feeders work between 300 and 1600 mm of width and 1 and 6 mm of thickness. Our 11-roller bouncer straightener servo line consists bouncing system that works in harmony with the straightener rollers. It is designed using a different technique in order to make the piloting work on multi-phased progressive dies and for the coil to fed properly. Servo feeder and straightener models allows automated feeding to the AZP high performance presses. Servo engine stimulation gear ties the gapless designed gearbox and straightener rollers together. It allows the angle between the die and the coil is 90° parallel. It has the feature of 50 mm of movement capability to the left or right from the feeder’s center. It feeds the coil materials in autonomous cycle, programmed speeds and high delicacy. Coil material feeding speed is 32 m / min.

Progressive tools are widely used in many areas of production. They enable the production of many details of the same shape or dimensions in a short time. That is why they are perfect for serial production of machine construction elements, household appliances or utility items. At the same time, they are also used in the production of single prototype elements. Among the many types of tools in this category are progressive dies and dies . The latter can be found, among others, in the automotive industry, where about 95% of elements are formed by forming on presses. Progressive dies, like other tools we supply, are used for plastic working of thin metals. They are multi-measure tools. They perform a specific element in a few movements (tacts), with a different feature assigned to each successive pressure of the die. Dies and other progressive tools consist of a die and a punch. Designed with the use of modern programs such as CAD, they can have very complex shapes.

The production of complex shaped elements formed from sheet metal requires the use of very precise tools. Designing them with the use of specialized programs such as CAD and supplementing with the visualization of the finished stamp is not always sufficient to guarantee a satisfactory effect. Therefore, a stamping simulation is essential to make sure it is correct before introducing progressive dies or cutting tools into production . Authors and PAM STAMP is the software we use to perform such a simulation. Both programs are a perfect solution for companies wishing to design and launch a new product. PAM STAMP stamping process simulation enables initial part feasibility assessment, tool design and full verification simulation. We can predict how the material will behave during each pressing phase. This solution makes it possible to optimize the process so that the pressed detail does not show any tendency to cracking, folding or excessive springback.
