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： A tool exchange apparatus comprises a first tool exchange arm for removing a previous tool mounted on a machine tool and returning the removed previous tool on a tool magazine and a second tool exchange arm for removing a new tool arranged on a tool magazine and setting the removed new tool to the machine tool, so that tool exchange operation can be achieved continuously. Further, each tool exchange arm comprises an upper finger and a lower finger. The upper finger is movable relative to the lower finger in order to remove only a lower tool (e.g. die) without exchanging an upper tool (e.g. punch).

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： To easily mount the ram drive unit on the upper frame of a punch press without being subjected to the influence of heat generated from the ram drive unit, the ram drive unit (23) is mounted on the upper frame symmetrical right and left when seen from the front. To accurately determine the angular position of a tool set, the punch holder (95) is fitted to the cylindrical pivotal member (113) with a positive fit tolerance to eliminate a or slip along the circumferential direction thereof. Further, the punch press is provided with a die holder (17) including a die fixing device (133) composed of a die push member (169), a hydraulic cylinder (165) and a piston rod (167) and further with an automatic tool exchange device (29) located equidistantly away from the process position and the tool exchange position.
