Including Deforming Tool And Cutting Tool Patents (Class 72/464)
  • Patent number: 4223545
    Abstract: A swaging tool assembly for also bending, cutting and flaring tubing which includes a tubing holding block connected to a tool support by a sliding stabilizer bar and a main bar rotated by a speed bar handle. The block has a cutter wheel cooperating with tube guides on the tool support. On the upper part of the support is rotatably mounted a head from which project a plurality of conically configurated flaring ends for flaring by swaging a tube held at one end in a seat on the block. A bending lever with telescopic handle is pivoted eccentrically to the lower end of the support which has tube bending means.

  • Patent number: 4081027
    Abstract: Shear rams shearing drill pipe passing through with blowout preventers encountering hydrogen sulfide are disclosed. The ram bodies are formed of an alloy having an upper hardness level of about Rc22 and the shearing blade and drill string engaging surfaces of the rams are hardfaced with a layer of nickel-based alloys, cobalt-based alloys, and tungsten-based alloys hard enough to shear the drill pipe. The layer of alloy is thin enough to avoid peeling off in use and warping the ram bodies when being welded to them. A number of embodiments and examples of the invention is disclosed.

  • Patent number: 4041753
    Abstract: An apparatus is disclosed for use in a press brake to be actuated between the ram and bed of such an apparatus to cut and form metal workpieces. The ram of the press brake receives a striker bar that engages a force member to coact with a bed member of the attachment to perform cutting and forming operations. The bed member of the attachment is fixed to the bed of the press brake and includes: a rigidly supported shear plate defining at least one recess to supportably receive a length of linear stock, and a yield block yieldably aligned with the rigidly supported shear plate which also defines at least one recess to supportably receive a length of linear stock. The force member is spring mounted above the bed member for separation from the bed member, and includes a movable shear plate defining at least one extension that is complementary to the recess in a rigidly supported shear plate, the two shear plates being supported in offset alignment.

  • Patent number: 3943745
    Abstract: Apparatus for piercing and coining a metal workpiece is provided. The apparatus includes a punch and a back-up die which accomplish the piercing, and a coining die located around the punch and movable with respect thereto to accomplish the coining. The punch and coining die are driven by a hydraulic ram which enables the overall apparatus to be relatively compact as compared to most heavy-duty dies and is adaptable for use at a station in a machine which also performs other operations on the workpiece. The workpiece is held precisely in position by a plurality of locators including adjustable fingers which contact and position the workpiece.
