20150352662 | HIGH BANDWIDTH LARGE SURFACE AREA ULTRASONIC BLOCK HORN - A large surface area ultrasonic block horn includes one or more shaped elements having a node at a mid-point of the shaped element that is narrower than opposed ends of the shaped element. | 12-10-2015 |
20150007704 | ULTRASONIC STEEL HORN FOR TIRE CUTTING AND METHOD OF MANUFACTURING - An ultrasonic tuned blade includes a base and a tire cutting edge made of a tool steel having a vanadium content which is at least about 8 percent. For example, the tool steel can have a combined vanadium, cobalt, and tungsten content that is at least about 15 percent. The tool steel can be formed into a simple block via a powder metallurgy process. The simple block can be milled into an ultrasonic tire cutting horn shape comprising a tuned blade including a base and a tire cutting edge. The ultrasonic steel tire cutting horn can be heat treated to provide the tool steel with a Rockwell hardness, for example, of at least about 50 HRC and less than about 64 HRC. The ultrasonic steel tire cutting horn can include a low friction or wear resistant coating. | 01-08-2015 |
20140374466 | METHOD OF ULTRASONICALLY WELDING MULTI-STRANDED MALLEABLE WIRES TOGETHER - Multi-stranded wires are clamped between an ultrasonic welding tip and an opposing anvil. The multi-stranded wires are made of a material that is more malleable than copper, or of a material that has a malleability that is substantially the same or greater than the malleability of aluminum. The plurality of multi-stranded wires can be clamped between opposing side surfaces to further form the wire bundle. Ultrasonic energy is applied to a first side of the wire bundle adjacent the ultrasonic welding tip. After termination of ultrasonic energy to the first side, the wire bundle is rotated 180 degrees relative to the anvil and ultrasonic energy is applied to a second side of the wire bundle, wherein the second side is oppositely disposed relative to the first side. | 12-25-2014 |
20140144592 | Method For Separating Disks - Disks stuck together in a stack are separated by placing the disks on a shaft of a vibratory apparatus and vibrating the shaft to vibrate the disks by contact of the disks with the vibrating shaft to separate them and also constrain the disks with the shaft as the disks are vibrated. | 05-29-2014 |
20130213552 | VIBRATORY WELDER HAVING LOW THERMAL CONDUCTIVITY TOOL - In accordance with an aspect of the present disclosure, a vibratory welder for welding parts together has a vibratory tool made from a material having a low thermal conductivity of no greater than 5 watt/meter degree Kelvin and also having a sufficient strength and toughness for vibratory welding. In an aspect, the vibratory tool is made of a material having a compressive strength of at least 80 MPa (megapascals) tensile and a fracture toughness (K | 08-22-2013 |
20130032297 | METHOD AND APPARATUS FOR SEPARATING LAMINATIONS - Parts stuck together in a stack are separated by placing the parts in a vibratory apparatus and vibrating the stack of parts with a vibratory head of the vibratory apparatus to separate them and also constrain the parts with the vibratory head as the parts are vibrated. | 02-07-2013 |
20120181250 | INFRARED LASER WELDING OF PLASTIC PARTS WITH ONE OR MORE OF THE PARTS HAVING A MODIFIED SURFACE PROVIDING INCREASED ABSORBTIVITY TO INFRARED LASER LIGHT - A method of using TTIr welding to weld together two high transmissivity plastic parts includes providing one or both parts with a modified surface that increases that plastic part's absorbtivity to laser light. The two parts are then laser welded by directing a beam of infrared laser light to the parts which are oriented so that the beam of infrared laser light first passes through one of the parts, impinges the modified surface (or surfaces) at a weld interface where the two plastic parts abut each other to melt the plastic parts at the weld interface, and then passes through the other plastic part. | 07-19-2012 |
20120085491 | Infrared Plastic Welding With Recirculation Of Unabsorbed Infrared Laser Light To Increase Absorption Of Infared Laser Light - Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated in an infinite loop back to the low absorption weld interface for reabsorption in the process. On each pass in the infinite loop, more infrared laser light is absorbed at the weld interface. | 04-12-2012 |
20120073414 | ULTRASONIC SYSTEM AND METHOD FOR CUTTING SOFT MATERIALS AND ULTRASONIC HORN BLADE THEREFOR - An ultrasonic system and method for cutting soft material has an ultrasonic transducer that vibrates axially at least one horn blade having a serrated edge so that when the horn blade is moved into the food product being cut, it is vibrating in a direction in and out of the food product to make a plunge cut. | 03-29-2012 |
20100224327 | PART SENSING HORN - A nodal sensing horn assembly for use in ultrasonic welding a first part to a second part that includes a nodal horn, a cavity formed within the nodal horn, and a sensing device at least partially disposed within the cavity. The sensing device senses a property, such as presence and/or orientation, of the first part and outputs a sensing signal in response thereto. | 09-09-2010 |
20100206487 | ULTRASONIC VIBRATION WELDER - The present invention solves the problem that a connecting portion between a horn and a vibration transmission rod has a tendency to get damaged and the problem associated with the structure in which a chip is attached to an end of the vibration transmission rod, which occur with the known ultrasonic vibration welder. A vibration transmission rod has an end surface serving as a vibration-and-pressure application surface, and a polygonal cross section. The vibration transmission rod is disposed at an end of a horn in such a manner that they vibrate together. The vibration transmission rod and a mass are formed separately. The mass applies pressure to a projection formed at a nodal point of the vibration transmission rod. | 08-19-2010 |
20100176184 | ULTRASONIC WELDING USING AMPLITUDE PROFILING - A method of ultrasonic welding aluminum parts together includes placing the aluminum parts in an ultrasonic welding apparatus and contacting at least one of the aluminum parts with a horn tip of a weld horn of the ultrasonic welding apparatus. A weld amplitude is profiled during a weld cycle of the ultrasonic welding apparatus by producing a high weld amplitude above 55 μm at the horn tip of the weld horn during an initial period of a weld cycle and producing a low weld amplitude below 55 μm at the horn tip after the initial period. | 07-15-2010 |
