Blanking Patents (Class 83/55)
  • Patent number: 10259032
    Abstract: Metal foil base material placed on lower blade is first restricted under pressure by lower blade and pad and then cut by a shearing action based on an engagement of lower blade side cutting edge and upper blade side cutting edge. Resin face sheets are fixed to the top surface of lower blade and the pressing surface of pad, the face sheets having a larger friction coefficient than that of these surfaces. By frictional forces imparted by face sheets, metal foil base material is prevented from being dragged and moved by the pressing force of the upper blade prior to cutting. Consequently, the occurrence of “burr”, “roll-up”, and so forth is eliminated thereby ensuring a good cutting quality.

    Abstract: In a method in which a cut line is formed on one surface of a planar glass material, and the cut line is allowed to extend in the thickness direction of the glass material, thereby cutting a glass substrate from the glass material, the cut line is selectively formed on a surface having relatively small surface waviness out of two opposing surfaces of the glass material. In the case of a glass material formed into a planar shape on a molten metal, the surface which has come into contact with the molten metal is selected as the surface having relatively small surface waviness. When a disk-shaped glass substrate is cut from the glass material, cutting is performed under conditions where either one of the thickness and the radius of the glass material and the maximum height of surface waviness of the glass material satisfy a predetermined relationship.

  • Patent number: 7076986
    Abstract: In a process for forming a linking element for a push belt for a continuously variable transmission, material is displaced from a central portion of the linking element during a blanking process, which central portion is substantially centrally located in the horizontal transverse direction. A blanking member which is applied during the blanking process, comprises a shaping surface which abuts against a front surface or a back surface of the linking element under the influence of pressure during the blanking process. The blanking member is provided with a relatively elevated central portion, which serves to displace material from the central portion of the linking element during the blanking process.

  • Publication number: 20040221698
    Abstract: An improved and more efficient perforation method for creating multiple punch holes during a finishing process of paper sheets and other sheet materials. A highlight of the present invention is the ability to select between at least two configurations of punch holes automatically, without manual adjustment, and “on-the-fly” without interruption of the sheet or paper flow. The perforation method utilizes two rotatable punches set at different angles such that when one intersects the sheet path, the other clears the sheet path. The speed of rotation is controlled such that the non-selected punch intersects the sheet path in a space between pitches.

  • Publication number: 20040074356
    Abstract: A process of, and apparatus for, the feeding of elongated strips of magnetic core stock material to successive stations of a multi-station die assembly for forming successive lamination blanks into individual magnetic core lamina is disclosed. To properly align the material with the corresponding dies, relative motion between each pair of successive lamination blanks is facilitated while those blanks are still joined. This relative motion is provided by significantly weakening the material in the region between two successive lamination blanks. In the illustrated preferred embodiment, the provision for relative motion includes removing the majority of the material interconnecting two adjacent lamination blanks without separating the individual lamination blanks from one another by use of an additional punch and die at the initial station for partially severing the strip between adjacent lamination blanks.

  • Patent number: 6718855
    Abstract: A rotary die cutter for cutting a series of irregular-shaped blanks from a continuous web. The rotary die cutter includes a male die cylinder that has a series of die cavities formed along its outer circumference. Each of the die cavities includes a surrounding cutting edge that defines the shape of the blank to be cut. The male die cylinder is pressed into engagement with either an anvil cylinder or a female die cylinder to form either crush-cutting or shear-cutting nips therebetween. The continuous web is fed into the cutting nip such that the cutting edges of the die cavities contact the web to cut the blanks from the web. A plurality of vacuum ports positioned in the die cavities along the outer circumference of the male die cylinder are connected to a source of vacuum contained in the male die cylinder to remove the die-cut blanks from the web. The die-cut blanks are vacuum-transferred to a stacking unit, while the scrap web is continuously discarded by air-conveying removal.
