摘要： The present invention relates to a device for replacing upper and lower dies in a bending processing machine, such as, for example a press brake. According to the invention, long upper and lower dies used in a bending processing machine are comprised of freely dividable sections that can be taken apart and recombined for convenient storage in an adjacent die exchange device. In the die exchange device, die holders are formed on the insides of a number of link members which are pivotably linked in a loop.

摘要： The present invention relates to a bending machine having a bottom die on which a sheet metal workpiece is supported horizontally in a frame body and an upper die which secures the workpiece by pressing against the bottom die. A bending beam is freely movable in the vertical direction to bend the edges of the workpiece when the workpiece is secured between the top and bottom dies. The bending machine also comprises a die changing system having a plurality of elevator bases each formed with a plurality of stages which store top dies separately and a device for controlling the elevator bases individually to prepare any combination of the top dies stored on the stages and a die exchanging device for furnishing the combination of the top dies in the proper position in the bending machine by transferring it from the stages.

摘要： Apparatus incorporated in a bending brake for making selective use of a preselected number of different dies which are to cooperate with reciprocating punches to make various bending operations. The dies are held in respective preassigned storage locations formed by a pair of racks jointly movable in the vertical direction. Disposed opposite to the rack pair of horizontal movement toward and away from same are a pair of die carriers which coact to carry a desired one of the dies out of the rack pair. A pair of die changer arms, pivotally mounted on the frame of the bending brake, transport a die to be replaced, which has been in use on a die bed, from the later on to the die carrier pair and, on their return stroke, transport the desired die which has been just carried out of the rack pair by the die carrier pair from the later on to the die bed. Comprising a set of electrical switches, a die identifier mechanism ascertains the identity of the replaced die and causes the rack pair to receive the replaced die in its preassigned storage location as same is subsequently carried back therein by the die carrier pair. Fluid actuated cylinders under the control of solenoid valves are employed for automatic operation of the apparatus.

摘要： In a tool storing device handling a tool mounting stocker in which a punch and a die of a press brake are mounted in one stocker with rear surfaces facing each other, each of the stockers is supported on both sides by endless belts having one driving shaft, and the endless belts are circulated so that each of the supported stockers does not protrude to a worker side, whereby a position of a path line of the appropriate one of the stockers can be freely positioned at a position of the path line PL of a tool holder on the press brake side. This enables rapid and easy tool replacement by a bending robot by storing not only the tool made of the punch and the die but also the hand for the robot together.
