The invention relates to a bending tool storage device () for storing bending tools (), comprising:

Bending tool storage device and method for feeding a press brake

A lower tool for a bending machine, in particular die bending machine, includes a longitudinally extended base body, which has, on its bottom side, a tool shank for being received in a guide slot of a tool holder and optionally tool shoulders in the transverse direction, and at least one friction reduction device on the bottom side of the base body for reducing a frictional force between the bottom side and the tool holder in the event of a displacement of the lower tool in the longitudinal direction, wherein the at least one friction reduction device is configured such that a weight force of the lower tool acting on the tool holder, while applying a prestressing force in the direction of the weight force, causes a resulting normal force of the lower tool onto the tool holder that is lower relative to the weight force.

Lower tool with friction reduction device

The invention relates to a support device () for a press brake, comprising a base frame () and a support plate () with a bearing surface () which can be positioned between a base position () and a maximum position (). The support plate () is arranged on a lever linkage system () which is connected to a drive unit () and which is designed as a parallel kinematics system. The drive unit () comprises a crank (), which is connected to a positioning drive () designed as a rotary drive (), and a rocker (), which is connected to the crank in an articulated manner. The rocker () is connected to the crank () by means of an eight rotary joint () and to the lever linkage system () by means of a ninth rotary joint ().
