The Multi-V main structure is simple; it consists of multiple elements of the same type which are built together into one tool. In case of damage it is simple and cost effective to replace one or more modules. It is possible to quickly change the desired V-openings by sliding in spacer bars on the front and rear side of the saddle and then lock the Multi-V section in place with two set screws. The spacer bars can be supplied by us or procured locally by the customer. This gives you the possibility to choose the V-opening that best fits the characteristics of the material to be processed; this is particularly useful when bending high tensile strength materials which have a great amount of spring back. The Multi-V is equipped with low friction, hardened roller bars which reduce marking on the outside of the part and also reduces the required bending force by 10% to 30% versus conventional bottom tools. The Multi-V is manufactured in lengths ranging from 500 mm to 1050 mm and the Multi-V lengths can be combined to make any required length. There are 4 standard Multi-V models available: Models B, D, E, and F ranging from a minimum opening of 24 mm to a maximum opening of 400 mm. See fig. 4.2 and the table. The Bottom Tool Holder (saddle) for the Multi-V is 40 mm thick as standard configuration and can be supplied as a flat bottom, with a tang, or as a bolt-down. Semi-automatic Multi-V versions are also available for the larger models E and F, whereby a chain drive mechanism is built into the bottom holders to open and close the Multi-V jaws via an electric drill, rather than manually.
