  • Patent number: 11117175
    Abstract: A forming operation on a workpiece clamps the workpiece between a first clamping jaw with a first shaping edge, and an adjustable second clamping jaw with a second shaping edge so that a portion projects between the shaping edges and afterwards a bending edge of an adjustable bending bar is guided at a distance past the shaping edges, whereby the portion of the workpiece is angled away in relation to the part of the workpiece that is clamped between the clamping jaws. The bending edge is guided on angling along a straight path of movement of the bending edge, and after the bending edge has passed the shaping edges, the shaping edges are adjusted along an adjustment path which approaches the path of movement of the bending edge.

    Abstract: An improved compound leverage hand seamer with removable blades. The hand seamer includes a pair of pivotably connected handles and a pair of pivotably connected seamer heads. Each of the seamer heads is connected to one of the handles at a first end and terminates at a second end in a substantially planar head segment having a flat, inwardly-facing mounting surface. A substantially planar, rectangular blade is removably mounted to the mounting surface of each of the seamer heads in a flatly abutting relationship therewith by a pair of threaded fasteners that engage threaded mounting holes in the blades and in the seamer heads. The blades can be conveniently removed and replaced if they become worn or damaged, or if user wishes, to install smaller or larger blades on the hand seamer.

  • Publication number: 20110100084
    Abstract: This invention is a manually operated tube bending machine with a power drive mechanism that is adjustably set to a desired bend speed. The bending machine includes a bending die, a counter die and a rotating hook die to form a desired bend into a tube or pipe. The tube bender includes a drive wheel with ratchet teeth around its perimeter. A drive pin grips one of the ratchet teeth. The drive pin is secured to a lever and torque bar. During each bending stroke, the lever and torque bar incrementally rotate the drive wheel a desired amount. The rotation of the drive wheel and hook die draw the tube through the bending and counter dies to bend the tube. An anti-spring back mechanism holds the position of the drive wheel while the power drive mechanism is advanced to grip the next ratchet tooth of the drive wheel.

  • Patent number: 7908899
    Abstract: Improved slide lock apparatus used in bending apparatus to bend stock to an acute angle. A hydraulic cylinder with a ram extendable under hydraulic pressure provides the bending power. The ram automatically retracts a slide from an first outward location when hydraulic pressure is removed to a second inward location for two separate bends to achieve an acute angle bend. This improved slide lock prevents any possible injury to the operator by covering a stop arranged to prevent the slide from moving outward a greater distance then the first outward location.

    Abstract: A powered conduit bending tool comprises a portable drive housing including a handle and having a powered drive gear. A bracket is secured to the housing defining a pivot connection spaced from the drive gear. A guide is operatively secured to the housing. A platform is pivotally connected to the bracket at the pivot connection and includes a driven gear operatively engaging the drive gear to controllably pivot the platform. A shoe is removably mountable to the platform and comprises a first bender defining a downwardly opening arcuate channel selectively positionable proximate the guide. A hook is proximate one end of the bender for engaging a conduit received in the channel. In use, the guide supports a conduit engaged by the hook and pivotal movement of the shoe driven by the platform deforms the conduit as it passes by the guide.

  • Publication number: 20110030446
    Abstract: An apparatus for forming a duct includes a bending apparatus and a support apparatus. The bending apparatus includes a table, a cut off beam, and a leaf hinged to a forward edge of the table. The cut off beam is movable toward and away from the table to clamp or release a metal web being fed forward across the table and the leaf. The cut off beam repeatedly clamps the metal web to the table while the leaf pivots toward the cut off beam to form a duct section. The support apparatus includes a cross rod movable along pivoting support arms. As the metal web is bent to form the duct section, the support arms and the cross rod are moved to internally support the duct section.

  • Patent number: 7735348
    Abstract: The invention relates to a method and a bending press for bending the boundary edge of a planar sheet for shaping into an open seam tube, with an upper tool shaped to correspond to the bend radius to be achieved and an opposed lower tool which may be displaced vertically, between which the boundary edges of the sheet which is clamped in place in the press frame may be bent into the desired boundary contour. The lower tool is provided with a straight working surface and mounted to pivot about a rotational axis whereby the pivot range is at least so large that a permanent planar contact between the working surface of the lower tool and the bottom face of the boundary edge is possible during the bending.
