WORKPIECE MANUFACTURING APPARATUS
A workpiece manufacturing apparatus includes a punch, which is provided in a lower die assembly and punches out a workpiece from an unprocessed material, and an ejector, which is provided in an upper die assembly so as to be capable of approaching and moving away from the lower die assembly. The manufacturing apparatus further includes a spring, which is provided in the upper die assembly and urges the ejector toward the lower die assembly, and a locking device, which locks the ejector with respect to the upper die assembly at a position at which the punch punches out the workpiece and releases the ejector when the die assemblies are opened. The locking device includes an actuator, which is provided in the upper die assembly and slides a slider between a locking position, at which the ejector is locked, and a releasing position, at which the ejector is released.
Method and device for precision cutting of workpieces in a press
A method for precision cutting of workpieces using a press which includes a press frame, in the press opening of which press frame a press ram, that works against a press table, is movably driven, wherein at least one of the press tools is formed as a cutting tool that includes a cutting punch, a downholder, a cutting die and a counter support. The cutting tool operates as a precision cutting tool. A lower tool part of the cutting tool includes a controlled retaining module that retains the counter support in a certain press ram position to enable ejecting the scrap.
Microtomic system and process using semiconductor chip grid
Provided is a microtomic system and process for the preparation of sections for microscope examination. A cutting edge in the system can cut through a sample block and produce a section one end of which remains attached to the cutting edge. A voltage generator can generate a voltage and apply the voltage between the cutting edge and a section receiver such as a semiconductor chip grid. Through electrostatic force caused by the voltage, another end of the section can anchor to the section receiver. The section is then spread on the receiver. The system is automatable, highly efficient, and does not need liquid to float sample sections, and can therefore maintain the integration of the sample sections.

Method and device for producing a stripping tool
The invention relates to a device (1) which is suitable for producing a stripping tool. Said device comprises a control unit (2), a receiving portion (3) for a stripper plate (4), a stripper flat-strip insertion device (5), and a stripper pin insertion device (6).
Lifting Device for Stripping and Blanking Operations
A deflectable lifting device can be mounted to a support form, work surface or other member of a material conveyance system. According to embodiments, the deflectable lifting device can have a base that mounts into the support, and a bendable arm arranged in the pathway of a material conveyance system, such as a paper stripping or paper blanking work station. When a sheet or web of material travels over the deflectable lifting device, the bendable arm can bend and deflect downwards, but still contact the sheet or web with a gently humped or arcuate portion, providing a small margin of elevation or lift to the sheet or web. The sheet or web can therefore be elevated above edges, holes, or other obstructions in the pathway that could jam or snag the delivery of the material.
