The invention relates to a punch carrier for a punch machine comprising a piston unit exchangeably arranged on the punch machine, and a punch holder arranged on the piston unit for exchangeably arranging a punch. Furthermore, the invention relates to a hydraulic punch machine comprising: a hydraulically driven punch carrier and a die adapted to a punch.

In order to provide a punch machine as well as a punch carrier for a punch machine that reliably allows an easy exchange of the punch to adapt to changing processing requirements, the punch holder has a punch seat transversal to the direction of the longitudinal axis of the piston unit, and a stripper that can be attached to the punch machine and has a passage for the punch, wherein the stripper is designed such that it fixes the punch in an operating position in the punch seat. Furthermore, it is provided that the punch carrier is designed according to one or more of claims 1 to 5.

Devices for separating two workpiece parts, e.g., metal sheets, from one another are described and include a workpiece mounting, a lifting device arranged on one side of the workpiece mounting, and a counter-holder arranged on the opposite side of the workpiece mounting. The counter-holder can be transferred into a fixing state and into a releasing state. One of the workpiece parts to be separated from one another is provided as a removal part, the other as a remaining part. For separating the two workpiece parts, the removal part, which is acted upon by the lifting device and supported by the counter-holder, can be moved by means of the lifting device perpendicular to the mounting in relation to the remaining part by a removal movement. At least in the releasing state, the counter-holder forms a rigid abutment in the lifting direction for the removal part. The rigid abutment has the effect that the removal part is aligned parallel to the mounting. Machine-based systems include a processing unit for producing two workpiece parts from a sheet-like workpiece and a separating device as described herein. Methods for separating two workpiece parts of a sheet-like workpiece are carried out by means of the devices described herein and can be part of a machine-based process.

A press machine is provided with a bottom dead center position correction control section, a selected lower bottom dead center position setting section, and a bottom dead center position switching section. The bottom dead center position correction control section is configured to perform, based on the selected bottom dead center position after the switching and the detected bottom dead center position, positional correction so that the actual bottom dead center position of the slide is adjusted to the selected bottom dead center position.

An integrated circuit production method. In some examples, the method includes receiving a leadframe comprising a plurality of in-production ICs in a forming machine, singulating the plurality of in-production ICs, forming leads of at least some of the plurality of in-production ICs to comply with dimensions and tolerances corresponding to an intended form factor of the plurality of in-production ICs, and separating, automatically by the forming machine, formed ICs from unformed ICs after the forming.

A component forming machine with jammed component mitigation. In some examples, the component forming machine can include a platform configured to receive a lower die that supports a plurality of components for forming and includes a void through which at least some of the plurality of components pass subsequent to the forming, a die press positioned above the lower die and configured to lower an upper die to exert downward pressure on the plurality of components to form unformed components and formed components, and a separation system. In some examples, the separation system is configured to interact with the lower die to permit the formed components to fall into the void and prevent the unformed components from falling into the void.

A punching tool that is capable of being used and modified independently of the shape of an opening to be punched, and is capable of being used for all round, angular and/or special-shaped tool contours. The punching tool generally comprises a cylinder with a fastener and a die having a lead-through for the fastener and a cavity with a stamp that is configured to connect to the fastener such that a spacer bushing is held to the cylinder.

A knockout punch tool includes a housing, a working head with a cutting die, a hydraulic circuit with an actuator to move the cutting die, a pump providing pressurized fluid, a pressure sensor, a fluid reservoir, and a controller. The controller monitors pressure during knockout operations, determines completion when pressure exceeds a first threshold indicating cutting has started then drops below a second threshold, determines when pressure derivative is at or near zero, verifies the derivative remains near zero for a preset time, and automatically initiates a hydraulic dump sequence to release pressurized fluid back to the reservoir, retracting the cutting die to home position.
