The disclosure relates to a tool storage device for a machine tool having a tool storage unit which can be mounted and displaced on a guide rail of the machine tool and is further designed to receive non-mounted tools for the machine tool.

In an installing method for installing divided upper tools to upper tool holders disposed to be spaced at an appropriate interval in a left-right direction in a lower portion of an upper table of a press brake, by using a tool changer, a round bar-shaped finger provided in the tool changer is engaged in a circular engagement hole provided at a central portion in the lateral direction of each divided upper tool. The divided upper tool is temporarily positioned in a gap between an upper tool holder to which the divided upper tool is to be installed, and an adjacent upper tool holder. The temporarily positioned divided upper tool is moved in the left-right direction to be installed to the upper tool holder to which the divided upper tool is to be installed.

An upper tool stocker for detachably supporting a plurality of divided upper tools in a press brake includes a stocker main body extending in a left-right direction, and provided with a left-right directional installing groove, attachment portions provided in upper portions of the divided upper tools being detachably installed in the installing groove, wherein the stocker main body includes a front-back directional cutout communicated with the installing groove to remove the divided upper tools downward or in the front-back direction from the installing groove.

A tool for a press brake includes a tool main body, an attachment portion formed on a base end side (one end side) of the tool main body and configured to be detachably attached to a tool installation portion of the press brake by using a tool changer, and a bending portion formed on a tip side (the other end side) of the tool main body and used to bend a plate-shaped workpiece. At a correspondent position, in a lateral direction, in the tool main body to a gravity-center position (the gravity-center position of the tool), an engagement hole having a circular cross-sectional shape to be engaged with a bar-shaped finger of the tool changer extends in a thickness direction (a direction of a thickness of the tool).

The invention relates to a tool magazine (26) for a bending machine (3), in particular for a press brake, wherein the tool magazine (26) has several storage rails (28), which are arranged in a magazine housing (27) and serve to hold bending tools (4), wherein the storage rails (28) are designed in such a way that several bending tools (4) can fit lined up one behind the other in the longitudinal extension (30) of the storage rails. The storage rails (28) can be pulled out from a front side (29) of the magazine housing (27) in the direction of the longitudinal extension (30) of the storage rails.

The invention relates to a tool storage system (32) as well as to a production facility (1) for free-form bending of workpieces (2) made from a metal sheet, by means of a bending press (3), comprising a tool storage unit (30), a tool manipulation unit (31), and a provisioning unit (55) having provisioning rails (56, 57). The tool storage unit (30) has an upper and lower storage rail (34, 35), which are disposed spaced apart from one another at a vertical distance, as well as locally fixed in place relative to one another. The tool manipulation unit (31) has tool manipulation devices (36, 37), wherein each of the same comprises a working rail (38, 42), an auxiliary rail (39, 43), a drawing-in device (40, 44), as well as a pushing-out device (41, 45). Each of the tool manipulation devices (36, 37) can be displaced laterally next to the storage rails (34, 35), along a longitudinal guide arrangement (46, 47). Furthermore, the invention also comprises a method for manipulation of at least one bending tool (4) in such a tool storage system (32).

An industrial installation having an automated sheet metal bending cell and an automated magazine, having a spatial and functional organization for automating flows of materials entering and leaving the cell, aimed at increasing, in a reduced enclosure, autonomy of operation of the cell without human assistance, as well as flexibility and productivity of the cell, the installation including: a press brake; a bending robot; a rail, generally called a track, on which a carriage supporting the robot moves; a system for dropping off and retrieving parts during operation; a mechanical or optical system for controlling indexing of parts to be bent; a magazine or a set of racks for bending tools comprising punches and dies; at least one attachment device for grippers; a programming and monitoring system for the press brake; a control console; an automated magazine; and a supply area for parts to be bent.

A tool to be used for bending a sheet metal is selected and tool layout data is generated in advance that includes a tool ID of the selected tool, mounting position information, and information on a place where each tool is housed in a tool stocker. A display controller controls a display to display information on a place where a tool is housed. A tool collation unit collates a tool ID read by a reader of a tool retrieved by an operator from a tool stocker with a tool ID of a tool included in tool layout data. In a case where the read tool ID matches a tool ID of none of tools included in the tool layout data, the display controller controls the display to display a message indicating that the tool retrieved by the operator is an incorrect tool.

The invention relates to a tool storage system (32) as well as to a production facility (1) for free-form bending of workpieces (2) made from a metal sheet, by means of a bending press (3), comprising a tool storage unit (30), a tool manipulation unit (31), and a provisioning unit (55) having provisioning rails (56, 57). The tool storage unit (30) has an upper and lower storage rail (34, 35), which are disposed spaced apart from one another at a vertical distance, as well as locally fixed in place relative to one another. The tool manipulation unit (31) has tool manipulation devices (36, 37), wherein each of the same comprises a working rail (38, 42), an auxiliary rail (39, 43), a drawing-in device (40, 44), as well as a pushing-out device (41, 45). Each of the tool manipulation devices (36, 37) can be displaced laterally next to the storage rails (34, 35), along a longitudinal guide arrangement (46, 47). Furthermore, the invention also comprises a method for manipulation of at least one bending tool (4) in such a tool storage system (32).

A roller hemming processing device that has first to fifth processing surfaces and that rolls the respective processing surfaces while pressing the respective processing surfaces against a hemming flange in such a posture that an axis of a roller is parallel to an outer panel is used. A pre-processed portion obtained by bending the hemming flange to form a right angle with an inner flange is molded by using the third, fifth and fourth processing surfaces in a stepwise manner such that the angle of inclination with respect to the axis decreases. The pre-processed portion is inclined toward an inner panel side by using the second processing surface. An inclined wall portion that is inclined to contact the inner panel, and a hem portion that is in close contact with the inner panel are molded by simultaneously using the first and second processing surfaces.
