Welding & assembly.New welding systems offer increased flexibility and ease of use, as well as small footprints. New ultrasonic entries include closed-loop power supplies, hand-held models, and a scan welder for large parts. Also, a new orbital vibration welder boasts faster welding cycles and ability to be tailored to the part shape. New vibration welders and a small hot-plate system were also shown. NEW ULTRASONICS ultrasonics, study and application of the energy of sound waves vibrating at frequencies greater than 20,000 cycles per second, i.e., beyond the range of human hearing. New 2000 series ultrasonic welders from Branson Ultrasonics Corp., Danbury, Conn., have improved closed-loop power supply, a higher-performance converter for faster welds, and real-time digital controls with 1-millisec sampling rate and amplitude stepping. Operating modes include time, energy, peak power, collapse, and absolute distance. The series includes 20-kHz models of 1100, 2200, or 3300 watts and two 40-kHz models of 400 and 800 watts. New F Series ultrasonic welders from Sonics & Materials Inc., Danbury, Conn., are voltage-stabilized with automatic frequency tuning and PLC amplitude control. The FDL FDL Free Documentation License FDL FireDogLake (website) FDL Fond du Lac (Wisconsin, US) FDL Facilities Data Link FDL Facility Data Link FDL File Definition Language FDL Flexor Digitorum Longus model includes a linear encoder A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal, which can then be decoded into position by a digital readout (DRO). for welding to preset depth. Units come in 15, 20, and 40 k/Hz with 700 to 4000 watts. Sonics & Materials also introduced hand-held ultrasonic welders with adjustable timers. The Millennium 4100 ultrasonic system from Dukane Corp.'s Ultrasonics Div., St. Charles, Ill., is said to be one of the first 40-kHz welders with 1000 watts of power. It's geared to small medical and electronic parts that require careful process control to prevent flash and stress cracking. Also new from Dukane is a scanning ultrasonic welder designed for fast assembly of large, rigid parts. Its stationary horn operates continuously while parts are guided under it on a conveyor belt conveyor belt One of various devices that provide mechanized movement of material, as in a factory. Conveyor belts are used in industrial applications and also on large farms, in warehousing and freight-handling, and in movement of raw materials. . ORBITAL & LINEAR VIBRATION The new CV-10 orbital vibration welder from Branson Ultrasonics offers programmable motion over a range from circular to linear. Unlike Branson's CV-12 orbital welder, which can be used only in clockwise and counter-clockwise motion, the CV-10 can be programmed in elliptical el·lip·tic or el·lip·ti·cal adj. 1. Of, relating to, or having the shape of an ellipse. 2. Containing or characterized by ellipsis. 3. a. , linear, or orbital motion Noun 1. orbital motion - motion of an object in an orbit around a fixed point; "satellites in orbital rotation" orbital rotation gyration, revolution, rotation - a single complete turn (axial or orbital); "the plane made three rotations before it crashed"; that can be tailored to the part shape or weld requirements. Branson's new Model VW-8UH linear vibration welder is the largest in the company's Ultra HyLine series. Features include color touchscreen controller with SPC 1. (business) SPC - Statistical Process Control. Something to do with quality management. 2. (body) SPC - Software Productivity Centre. 3. (company) SPC - Software Publishing Corporation. 4. charting, three modes of welding control (meltdown meltdown Occurrence in which a huge amount of thermal energy and radiation is released as a result of an uncontrolled chain reaction in a nuclear power reactor. The chain reaction that occurs in the reactor's core must be carefully regulated by control rods, which absorb , time, and absolute height), and a hydraulic clamp with four clamp pressures and a separate hold pressure to allow meltdown velocity profiling. Branson also introduced a 3 x 3 ft Mini II vibration welder that can handle small and irregularly shaped parts measuring up to 7 x 9 in. The unit can be mounted on casters casters the small rubber wheels on surgical trolleys, patient stretchers, mobile equipment. conductive casters the casters are impregnated with carbon to facilitate the dispersal of static electricity from equipment. and rolled up to a molding press. ELECTRIC SPIN IS PRECISE Two new spin welders with direct-drive electric motors were introduced by Sonics & Materials. Settable rpm controls and direct drive of the tooling brake and dutch system are said to provide greater part-to-part consistency. Model 1010 has a fixed 10-in. opening while Model 1020 is adjustable from 10 to 20 in. New relay-logic and PLC power supplies are also offered. Branson Ultrasonics' new PMA PMA (papillary-marginal-attached), n a system of epidemiologic scoring of periodontal disease devised by Schour and Massler in which the symbols denote the areas involved in gingival inflammation. PMA Progressive muscular atrophy 95 spin welder is servo-driven with controls that allow adjustment of hold time, turns per weld cycle, rpm (1000 to 5000 range), and radial tool orientation to 1 [degree]. SMALL HOT-PLATE UNIT New compact HH-15 hot-plate welder from Branson Ultrasonics has a small horizontal platen in order to process parts that are not adaptable to Standard vertical hot-plate welders. |
