A hydraulically operated handheld device and a method of operating same are provided. The device includes a hydraulic pump, a moving part, a fixed part and a return valve with an associated valve seat. The moving part is moved into a working position due to the buildup of a hydraulic pressure by filling a hydraulic chamber with hydraulic medium from a reservoir with the aid of the hydraulic pump. The moving part can be automatically moved back from the working position into an end position upon reaching a predefined working pressure by opening the return valve. The hydraulic pressure acting upon the return valve is increased by a separately triggerable pressure increase, which results in opening of the return valve, in a hydraulic medium volume located upstream of the return valve in a flow direction of the hydraulic medium during the movement into the end position.

A rule to be inserted into a die-board that is pressed onto a plate matter, the rule including: a multi-edge cutting blade having a cutting blade edge, the cutting blade edge divided into multiple sections with multiple spacings between the multiple sections; and a plurality of connecting pieces configured to fit into the multiple spacings and to provide support for the multiple sections of the cutting blade edge when the rule is pressed onto the plate matter.

A metallic stamp and die for the craft industry comprises a predetermined acid-etched design on a surface of a metallic plate. A first layer of a metallic paint is applied over the front and back surfaces of the metallic stamp and die. A second layer of a rubber paint is applied over the metallic paint. The metallic paint facilitates bonding of the rubber paint to the metallic plate and increases the life of the coating of the rubber paint. The rubber paint is configured to absorb and store an ink and facilitate transfer of the ink to one or more substrates, thus enabling stamping of the design on the substrate. The metallic die can be configured for a plurality of uses, such as embossing, cutting, heat-foiling, stamping, scoring, and inserting patterns or designs in a plurality of substrates.

A method for manufacturing a ball pen tip, in which a spring for biasing a ball is assembled to the ball pen tip, includes punching the ball pen tip by a punch from a rear end of the ball pen tip along a central axis direction of the ball pen tip to form a plastic flow ridge formed by plastic flow upheaving radially inward from an inner peripheral wall surface of the ball pen tip to assemble the spring to the ball pen tip by the plastic flow ridge.

An electrode cutting device is provided. The electrode cutting device may perform a full-width cutting process and an edge cutting process together to simplify the manufacturing process, thereby significantly improving work efficiency. Particularly, an edge of the electrode is uniformly cut to prevent defects from occurring.

A pouch cell cutting apparatus according to an embodiment of the present disclosure, includes a top knife and a bottom knife for cutting a sealing part of a battery cell which includes a cell case and an electrode assembly housed in the cell case, wherein both side parts of the top knife comprises protrusion parts protruding toward the recessed parts formed on both side parts of the bottom knife, respectively, and wherein a corner part of the battery cell is cut by the protrusion part.

The invention relates to an apparatus comprising a separating tool and comprising a counterpressure plate for producing contour geometries in adhesive-containing composite materials, wherein the separating tool can be moved in translational tool stroke directions between an inoperative position and a parting position normal to the counterpressure plate, and also to a method for producing contour geometries in adhesive-containing composite materials by means of an apparatus of this kind. The separating tool and the counterpressure plate can be actuated relative to one another by means of at least one actuator in at least one excitation direction with a ramp function and/or with a jump function. Each of these excitation directions lies in a parallel plane to a cutting edge plane of the separating tool. The present invention permits reliable separation of a stamped grid from laminate sections which remain on a carrier film.
