Detailed planning is essential for every vehicle manufacturer designing a production line and its sequences. Each die in production must be optimized as the speed and reliability of simultaneous or sequential steps are crucial for production efficiency. When selecting the solution for each die, the manufacturer must meticulously balance the force, reliability, and consumption of space of the components.

Flanging sheet metal at a small angle is a challenge since it leaves only a very narrow space for the support cam behind the filler slide. Furthermore, the operation demands accuracy in timing and force. It must also be reversible to allow the removal of the vehicle part from the die after the flanging.

When forming a roof, front fender, or side of a vehicle, it is common practice to use compressed air cylinders to apply force to moving tool parts. This solution works when less power will suffice and when bulky compressed air cylinder parts will fit into the configuration of the production line.

But when the list of requirements calls for a stronger and more space-saving, performance than can be provided by compressed air cylinders, a hydraulic-driven, multi-functional, and compact solution like the KALLER Flex Cam will solve the case.

With the Flex Cam, flanging an edge at a 110-degree angle is no problem. Sheet metal is pressed around a filler slide, while the filler slide is locked into position with a support cam.

The support cam is pushed into position from below. Thanks to the hydraulics, the filler slide is supported with full autonomy, sufficient force, and perfect timing. Moreover, the operation can be done at different angles.

Retraction of the cam is done with the same precision and timing, ensuring efficiency and preventing jam.

The hydraulic-powered cam is slender and moves freely between other tools in the press, even in a very narrow space.

KALLER Flex Cam is a compact hydraulic-powered cam. It has the capacity to push a support cam from any angle and with ample force to support a filler slide that in turn supports the flanging of the sheet metal.

It is powered by Gas Springs that execute with excellent timing. Its reliability, durability, and longevity require minimal service, and it performs with high force, autonomy, accuracy, and timing. Small but strong, the KALLER Flex Cam can apply 25 times the force of a compressed air cylinder.

The KALLER Flex Cam has become a standard component for many vehicle manufacturers and is often included in different vehicle manufacturing tool standards globally. With a proper set-up, performed more than 2,000,000 cycles without any servicing required.
