Bottom Tool Holders have a variety of functions. They are often used on shorter length press brakes where a crowning system is not required or where there is a crowning system already built into the lower beam of the press brake. Bottom tool holders can be outfitted with hydraulic clamping pins for quick changeover of segmented single V-dies. They can also be used as necessary distance pieces or they  can be outfitted with wedges on the bottom to bring the ram and bed parallel to each other. Wila Bottom Tool Holders stand out in their functional design, their completely integrated clamping system for bottom tools and their easy, often automatic, operation. With our extensive range of models available, we are able to provide the right  Bottom Tool Holder to meet your particular need

Hydro Power Packs

Wila also supplies a Hydraulic Power Pack for OB Bottom Tool Holders which have hydraulic clamping capability). The Power Packs can be operated via remote control or tied to the press brake control. In cases where the customer changes their bottom tooling infrequently, Wila also offers a manually operated Hydraulic Power Pack at very attractive pricing, which allows you to take advantage of the speed and flexibility of hydraulic clamping at a lower price.

Ty/Tx

In a number of cases, a separate crowning system is not required, either because the press brake is very short and has limited deflection or because a crowning provision is already built into the lower beam. However, there are other provisions which are built into Wila Bottom Tool Holders that are necessary in order to produce accurate parts consistently, namely, the ability to perfectly align bottom tools and the ability to eliminate tolerances in the Y-axis (Ty). These local deviations, as well as inaccuracies because of wear, can easily be corrected. Production losses and costs for scrap and re-work are no longer necessary and the life span of the machine is increased as well. Across the entire length of the machine, the Bottom Tool Holder can be aligned with adjustment screws in the X-axis (Tx) in relation to the back gauge. Exceptionally stringent requirements to the straightness of the lower beam are no longer necessary.
