Class / Patent application number | Description | Number of patent applications / Date published |
072306000 | Plural or complex apparatus (e.g., with plural operations) | 14 |
20080209973 | SLIDE LOCK - 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. | 09-04-2008 |
20080223101 | GRIPPING APPARATUS FOR GRIPPING AND HOLDING ELONGATED WORKPIECES, IN PARTICULAR FOR BENDING MACHINES - A gripping apparatus for gripping elongated workpieces comprises a housing, carrying two pivotable gripping jaws which are movable between opened and closed positions, as well as a guiding body, in which the housing is displaceably supported. | 09-18-2008 |
20090056401 | WIRE BENDING MACHINE COMBINING A SEQUENTIAL SHAPING DEVICE AND A DEVICE USING A TOOL PLATE - The invention concerns a machine for automatically shaping components via different types of bending provided in a common plane or different planes. The machine includes a first device for performing a sequential shaping with standard tools by individual bending, and a second device using a tool plate. Both devices are managed by a single digital control. The method for controlling such a machine is characterized in that digital control provides the possibility for producing a blank of a component by individual bending on the first device followed by transfer of the component on the second device for finishing the component. Digital control provides the possibility of shaping one part of the component on the first device and shaping the remaining parts on the second device. The digital control also provides the possibility of using each machine alone and the possibility of using both machines for producing the same component. | 03-05-2009 |
20090301160 | FLANGING MACHINE AND METHOD FOR SPIN-FLANGING WORKPIECES - A crimping device ( | 12-10-2009 |
20100281940 | VERTICAL AIR COMPLIANT HEMMING HEAD - The present invention pertains to a hemming head for performing a hemming operation which comprises a support housing adapted for securement to a robot arm on a first end, and having a first roller rotatably secured to a second end. The first roller has a cylindrical body, a head, and a groove between the body and head. The head has a diameter greater than the body, and the groove has a diameter less than the body. The groove also includes a canted surface that conjoins with the head. In use, the cylindrical body is adapted to engage and force a workpiece edge downwardly to a first position and the canted surface is adapted to engage and force the workpiece from the first position to a second position. | 11-11-2010 |
20110048094 | HORIZONTALLY STACKED HEMMING PRESS - A horizontally stacked hemming press includes a horizontally disposed base. A first vertical support is mounted on the base and disposed generally perpendicular to the base. A linear track is mounted on the base. A horizontally disposed die stack including a plurality of cooperably operable die sets are horizontally arranged in series and moveable along the linear track. Each die set includes a pair of vertically disposed die shoes. A guided press platen is horizontally moveable along the linear track. A second vertical support is mounted on the base distal from the first vertical support and disposed generally perpendicular to the base. A drive mechanism is supported by one of the supports and connected to the press platen for opening and closing the die sets. Actuation of the drive mechanism horizontally moves the press platen and thereby horizontally opens one of the die sets. | 03-03-2011 |
20120318031 | DUCTMAKING APPARATUS - A ductmaking apparatus bends a metal web to form a duct blank having a lock seam with male and female portions. Prior to shearing off the duct blank, the apparatus bends the web to form a lock tab that secures the lock seam during subsequent handling of the duct blank. | 12-20-2012 |
20150020565 | PART CORRECTING DEVICE FOR AUTOMOBILE PART - A part correcting device for an automobile part may include a body in which the part is disposed, a hydraulic apparatus which presses and fixes one side of the part disposed in the body, a warpage correcting apparatus which corrects a warpage of the part by rotating the other side of the part left or right while fixing the other side of the part disposed in the body, and a deformation correcting apparatus which corrects an angle of the part by pressing flanges formed on both sides of the part downwardly while fixing the flanges. | 01-22-2015 |
20150336149 | S-Lock Flashing Member Forming Apparatus - A forming apparatus includes a work surface and three die members movable relative to the work surface for bending a sheet metal flashing member to form an S-shaped end joint known as an S-lock or slip lock joint. | 11-26-2015 |
20160175909 | PIPE BEND DIE UNIT, AND PIPE BENDING APPARATUS HAVING THE UNIT | 06-23-2016 |
072307000 | With means to advance elongated work (e.g., pipe elbow crimper) | 4 |
20090000344 | Automatic bending machine for manufacturing of steel rule cutting dies - A setup method for preventing a “two-leaf cutting” by only operating a machine without using fingers in cutting an end of a strip blade material having an enclosed rectangular geometry. The steps include: the strip blade material being once advanced to a position, where “two-leaf cutting” will not occur; then a cutting tool being lowered; a cutting tool tip of a cutting tool component being lowered to a level of the same as or under that of a top edge of the strip blade material; then the strip blade material being retracted; and finally, the strip blade material being retracted by the same amount as that of the advance from the desired position. | 01-01-2009 |
20100170318 | ELBOW FORMATION APPARATUS - An apparatus for forming and rotating interconnected sections of a cylindrical sheet metal workpiece to provide an elbow. The apparatus includes a frame, a head rotatably arranged within the frame and a tool ring mounted to the frame, the head and tool ring being co-operable for sectioning and joining segments of the workpiece. The apparatus also includes a drive drum mounted within the frame for gripping and rotating the segments, and a control module for selectively activating the head, the ring, and the drive drum to form an elbow. | 07-08-2010 |
20110132056 | Pressing device for bending - The present invention provides a pressing device for bending, in which a pipe is held between a bending die having a shape corresponding to a shape of bending and a clamping die revolvable around the bending die, and, when the pipe is bent by revolving the clamping die around the bending die, an axial compression force is applied to the pipe. The pressing device for bending includes a movable table arranged movable in an axial direction of the pipe, a first cylinder provided to the movable table and able to press a rear end of the pipe, and a second cylinder provided to the movable table and able to press a fixed side in a direction opposite to a direction in which the first cylinder presses the pipe. | 06-09-2011 |
20110247386 | GRIPPING DEVICES - A gripping device comprises a support frame defining an axially extending internal space for receiving a part that is to be gripped and a plurality of jaws carried by the support frame. The jaws each have an end face and are connected with the support frame such that an axially directed force applied to the end faces causes axially and radially inward movement of the jaws for gripping a part received in the internal space. | 10-13-2011 |
