    摘要: The disclosure relates to a modular die for blanking a sheet for manufacturing individual blanks successively by a stroke of a ram of a press on tool parts for the blanks, the die having frame part (1,2), tool parts (3,4) placed in a gap between the frame part (1,2), where the tool parts (3,4) is maintained in position in the gap (5) by fixation parts (8,9,10,11). The fixation parts (8,9,10,11) engage with lateral surfaces (12,13,14,15) of the tool parts (3,4). Surfaces of the fixation parts (8,9,10,11) has a geometry congruent with a geometry of lateral surfaces (12,13,14,15) of the tool part (3,4). The disclosure also relates to tool parts of the modular die, to a method for operating the modular die and to a use of the modular die for manufacturing, as example, brake shims.

    摘要: Discussed is a notching apparatus and method for a secondary battery. The notching apparatus includes: a notching unit notching a portion of an electrode that is continuously supplied; a drying unit drying the electrode while the electrode discharged from the notching unit passes therethrough; and a collecting unit collecting the electrode discharged from the drying unit, wherein the drying unit includes a heating body provided with a drying space that is a passage through which the electrode passes therein, and lamp parts mounted on the heating body to irradiate infrared rays onto a surface of the electrode while the electrode moves through the drying space.

    摘要: A seat length adjuster for a vehicle seat may have two rail pairs, each pair formed by an upper rail and a lower rail. The upper rail is provided with openings and the lower rail has through holes. At least one spring-loaded, movable locking member may be provided. The locking member carries toothlike protrusions on its two opposite lengthwise sides, which are movable from a released position into the locked position both into the openings and into the through holes. The openings and/or the through holes have contact regions for the toothlike protrusions of the locking member and at least some of the toothlike protrusions have a respective undercut on both tooth flanks. In the locked position a projecting edge resulting from this on the respective tooth flank lies opposite the contact region and/or touches this contact region.

    摘要: A base body for a metal-sealing material-feedthrough subject to high pressures in an igniter for an airbag or a belt tensioning device. The base body for the metal-sealing material feedthrough is an element formed by a process of cold forming and having a ring-shape or a plate-like shape. The element includes a feedthrough opening extending from a front side of the element towards a rear side of the element. There is a metallurgic section in the element of the base body with structure-lines or flow-lines that are bent due to a reshaping process of the process of cold-forming.

    摘要: A press die includes a fixed die, a first movable die, and a second movable die to cut out a product from a metal plate member, and a scrap cutter to cut scrap that is not part of the product. A fixed-die cutting blade of the fixed die is configured to have a fixed-die cutting blade relief portion formed near a base end of the protruding scrap cutter and recessed inward to the product side from the cutting line of the product. The fixed-die cutting blade relief portion includes a substantially arc-shaped cross-sectional portion corresponding to a machining radius of a machining tool for forming the scrap cutter. A first movable-die cutting blade of the first movable die has a movable-die cutting blade protrusion to cut the metal plate member inward to the product side from the cutting line of the product.
