A die-pressing die used for die-pressing a workpiece includes a die body on whose upper face a die hole is formed and on whose bottom face a discharge hole for discharging dusts of the workpiece is formed, and a roller unit disposed within the die hole and having a roller protruding upward from the upper face of the die body. A collection passage for collecting the dusts is formed at a peripheral edge portion of the die hole. One end of the collection passage is opened at the upper face of the die body, and another end thereof is opened to the discharge hole. The collection passage is configured to suction air due to a negative pressure state in the discharge hole.

Machining plate-like workpieces

A method for machining a plate-like workpiece with a processing machine includes forming a receptacle in the plate-like workpiece for an insert part and machining the receptacle based on one or both of an orientation at which the insert part is to be inserted into the receptacle and a side of the plate-like workpiece from which the insert part is to be inserted into the receptacle. The method further includes running a machining program to carry out the forming and the machining of the receptacle. A computer program product is provided to configure a programming system by which the machining program is generated.

SYSTEMS FOR ENHANCING FUNCTIONALITY OF INDUSTRIAL PUNCH PRESSES
20190060972 · 2019-02-28 ·

Complementary systems are provided for use with industrial punch presses which enhance the functionality of the presses relative to the machining of workpieces. The systems can be adapted to function with certain already-existing structure and operations of the presses, to maximize overall effectiveness and efficiency in using the systems with the presses. Alternately, or in combination, the systems can be linked to one or more functionalities of the punch presses, whereby these functionalities can be used in manipulating the systems when used with the presses.

NUMERICAL CONTROLLER
20190033817 · 2019-01-31 · ·

A numerical controller generates movement command data, and performs an interpolation process based on the generated movement command data to generate and output interpolation data. Further, in the case of a state in which a press operation in punch press machining is started from a different position from a position of a preset rising edge, an overlap time is calculated based on a position of a punch head when the press operation is started, and an output timing of interpolation data related to an axis controlling the press operation is controlled based on the calculated overlap time. In this way, even when there is a change in press stroke, a dead time may be prevented from being generated.

Method and device for producing tear-open lids

A method for manufacturing a tear-off lid (27). A lid blank (9) is punched with a punching tool (1, 5) having a die (6) and a cutting punch (2, 3) to form a lid ring (8) with a central removal opening (17) surrounded by a sealing flange (18). The edge of the removal opening (17) is then formed by drawing to a collar (20) projecting from the sealing flange (18) on the intended inside of the lid (underside), the collar (20) is rolled up at its free end and a tear-off foil (24) is sealed or glued onto the sealing flange (18) on the intended outside of the lid (upper side). In accordance with the invention, the die (6) is arranged on the inner side (bottom) of the lid and the cutting punch (2, 3) is moved into the die (6) from the outer side (top) of the lid while punching out a punched pad (16) and the punched pad (16) is conveyed by compressed air through the die (6) to a conveyor (33) by means of which it is removed from the tool area. It has been shown that by this measure the known and established processes and devices for the production of tear-off lids can be modified with very little effort in such a way that during the punching of the lid blank (9) the punching or cutting pad is produced on the intended inner side (underside) of the produced lid ring (8), which is desirable when producing lids with re-verse curl.
