  • Patent number: 8997613
    Abstract: With known trimming shears having a pair of scrap-cutting blades on the discharge side, the moving upper scrap-cutting blade must be moved as closely as possible past the trimmed plate edge in order to push the cutoff edge still hanging on the plate downward against the lower fixed scrap-cutting blade, which requires precise adjustment of the upper scrap-cutting blade. To that end, according to the invention, the distance between the upper scrap-cutting blade (2) or the lower scrap-cutting blade (3) and the trimming blade plane (5) is set prior to trimming in accordance with the thickness of each heavy plate (10) to be trimmed by displacement of the upper scrap-cutting blade (2) and/or the lower scrap-cutting blade (3) in a displacement direction with at least one component transverse to the trimming blade plane (5).

  • Patent number: 8602670
    Abstract: In a scissor type automatic cutter 20, as the movable knife 22 pivots, adhesive between the web liner 11a and the continuous label 11b medium is squeezed out from the label paper 11 at the distal end side of the movable knife 22 and sticks to the fixed knife 21 or the movable knife 22. Because a notched opening 44 is formed in the upstream edge 50a in the paper discharge direction at the other edge part in the paper width direction of the substantially horizontal stage surface 40, if adhesive sticking to the fixed knife 21 or movable knife 22 moves to the stage surface 40 side, the adhesive can be removed from the notched opening 44 and does not accumulate on the stage surface 40.

  • Publication number: 20120167740
    Abstract: An improved shear cutting blade comprising a plurality of opposing countersunk fastener holes and four cutting edges is disclosed. Four cutting edges and two mounting surfaces are provided, along with threaded, countersunk holes to allow fasteners to secure the blade in multiple orientations. The blade is ideally utilized in a compacting and baling process, wherein loose scrap metal and other material are pressed from a collection point and into a compaction chamber, wherein the blade is passed over the material as it is pressed into the chamber, shearing the debris into a compact, baled form. The blade can be rotated and secured against either mounting surface, and rotated to allow use of any of its four cutting edges, providing reusability and improved service life of a single blade during operation.

  • Publication number: 20120131977
    Abstract: A forming machine comprises a shearing device for shearing off a section of a bar stock, a forming station for forming the sheared off bar stock section and a transport device for the bar stock. The shearing device has two shearing blades, of which one is movable transverse to the longitudinal extension of the bar stock. The shearing blades each have an assembly block and a shearing insert attached to this. For one of the shearing blades, the shearing insert is made of a heat-resistant, break-proof and thermal shock-resistant hard material and essentially has the form of a cylindrical half-shell. This shearing insert is arranged in a reception recess of the assembly block, which is adapted in shape, and is releasably clamped to the assembly block by means of screwed clamping blocks.

  • Patent number: 8166854
    Abstract: In a shearing device (10), a plate-like work piece (50) is seated on a die (20) positioned on a lower side thereof is clamped by a pad (30), so that a predetermined portion of the work piece (50) is processed into a predetermined shape by a punch positioned on an upper side thereof. The punch (40) integrally has a heel portion (41). The heel portion is so as to broadly contact an outer peripheral face (51) of the predetermined portion to be processed of the work piece (50), thereby restraining the outer peripheral face (51) from moving in an outward direction perpendicular to a thickness direction.

  • Publication number: 20120000336
    Abstract: An alloy, such as a tool steel containing, in percent by weight, 0.5%-0.7% carbon; 1.80%-2.50% chromium; 0.90%-1.20% molybdenum; 3.50%-5.50% nickel and 0.60%-1.50% vanadium. The steel alloyed accordingly is eminently suitable for heat treatments for influencing strength. With a carbon content of less than 0.7%, a partially martensitic metal structure having a high ductility can be formed by way of hardening processes. Due to surface hardening, the carbon content may in some portions on the outer surface be greater than 0.7%.

  • Patent number: 8037795
    Abstract: A trimmer for trimming brochures has lower blade holders and upper blade holders for top cutting blades and bottom cutting blades lying opposite them. The trimmer further has a guide rail configuration and tensioners by which the lower blade holders can be locked on the guide rail configuration. Accordingly, the tensioners can be actuated from one and the same side of the trimmer. This has an advantageous effect on the time required for changing over the trimmer from one brochure format to another.

  • Publication number: 20110226111
    Abstract: A VCT tile cutter comprises a movable top blade and a fixed bottom blade capable of shearing a VCT tile. The cutter includes a blade carrier in which the top blade can be slid horizontally in relation to the fixed position of the bottom blade beneath it. In this way, an outer edge of the top blade can be slid horizontally and positioned over a point in a tile that corresponds to the end point of a desired partial cut in the tile. When a crankshaft mechanism is activated, the blade creates a partial cut in the tile from the perimeter of the tile to a point in the tile corresponding to the location of the end of the movable blade. The blade may be straight or faceted and may have partially or completely relieved edges to enhance the capability of the cutter to perform partial cuts in the tile.
