Abstract:
The invention involves staged press brake tooling combinations. In some embodiments, the invention provides a staged press brake setup. In other embodiments, the invention provides a staged quick-change multiple forming recess press brake die.
Abstract:
A multi-tool having a plurality of tool-receipt openings adapted to receive respective tools. The multi-tool can be used on turret presses, single-station presses, other industrial presses, or other fabrication equipment.
Abstract:
A cartridge for a machine tool is provided. The cartridge has a main body, two punch-retention arms, and two die-retention arms. Preferably, the cartridge also has a stripper locator base. In some embodiments, the cartridge is provided with an electronic information storage device.
Abstract:
Press brake tools suitable for punching and/or otherwise deforming workpieces, such as sheet metal. Provided in some embodiments are a press brake tool and a press brake tool holder, in combination. Methods of using press brake tools are also provided. In certain embodiments, the tool has a mechanism for locating and/or seating, such as a tool-seating mechanism adapted for moving the tool parallel to a pressing axis of a tool holder on which the tool is to be used.

Abstract:
A tool holder (10) for securely holding a forming tool (2) in its intended position on a press brake. The tool holder includes a tool holder plate (1) having first (7) and second (8) receiving surfaces oriented to respectively engage first and second mounting surfaces of a press brake tool, an actuator arm (12) movable toward and away from the tool holder plate and having a camming surface (14), a clamp (11) carried by the actuator arm and being movable with respect to the actuator arm toward and away from the respective receiving surfaces of the tool holder plate, and a cam (15) surface on the clamp oriented to be engaged by the camming surface of the actuator arm to receive force therefrom in response to engagement of the respective camming surfaces of the actuator arm and the clamp. The force thus received has substantial force vector components normal to the first and second receiving surfaces of the tool holder plate to press against these surfaces, respectively, the first and second mounting surfaces of the tool.
Abstract:
Punch holders and corresponding punch configurations configured to increase the ease and speed by which maintenance and/or modification of punches used with the holders can be performed. In some cases, the punch holder (70) can be configured with one or more upper (72) and lower (74) collars operatively situated on differing areas of the holder (70), with each collar adapted to perform a different action with regard to a punch (50) held by the holder (70). In some cases, when the upper collar (72) is rotated, a corresponding height adjustment of a punch (50) held by the holder (70) results. In some cases, when the lower collar (74) is rotated, a punch (50) held by the holder (70) is released.
Abstract:
Press brake tool holders (TH) suitable for releasing and securing press brake tools (TL) . Comprising a push plate (70) and a push member (80) compled to the push plate extending in the tool-mount channel of the tool holder when the push member is operated by the push plate which is driven by a driver (D) . Provided in certain embodiments are a press brake tool holder and press brake tool, in combination. Methods of using press brake tool holders are also provided.
Abstract:
A length compensator for a punch tool enabling the punch to be utilized in an autoloading punch press utilizing a robotic tool transfer system to transfer punch tools into and out of the punch press. The compensator includes a first portion attachable to an end portion of the punch tool remote from the punch tip and adjustable lengthwise of the tool, and a second portion positioned to be further from the work contacting surface that the first portion when the latter is mounted to a punch tool. The second portion has an upper ram-engaging surface and is movably mounted to the first portion to enable movement of the second portion lengthwise of the punch tool between a first position in which the first and second portions are spaced from each other a predetermined distance and a second position enabling ram force to be delivered to the end portion of the punch tool. A spring is provided to urge the second portion into its first position, thereby increasing the length of the punch tool sufficiently to enable it to be gripped by the robotic transfer system.
Abstract:
An adjustable die holder for a press brake comprising an elongated base block adapted to be attached to a jaw of a press brake and having a first bore formed therein and a horizontal upper surface; a top plate slidable on the upper surface of the base block. The top plate bears a die holding element and having a second bore formed through it, the second bore being in substantial alignment with the first bore. A die carried by the die holding element has a working surface oriented away form the die holding element. Extending through the first and second bores is an elongated threaded member having external threads. A handle is provided for rotating the threaded member with respect to an internally threaded element which threadingly mates with the elongated threaded member, the handle having an unlocked position wherein the top plate is free to slide upon the upper surface of the base block and a locked position wherein the top plate is locked to the base block.
