System Solves Challenges of Free-Form Clamping

Roemheld has developed a flexible clamping and supporting system (FSS) that solves the challenges of clamping free-form surfaces for the aerospace, automotive, rail and marine industries. The FSS from Roemheld enables the clamping and supporting of various workpieces with different free-form surfaces. At the core of the design of the Roemheld FSS clamping fixture is the use of Kostyrka UHF clamping and supporting elements. These can be used in any number to create the workpiece contact surface.

Because each UHF element can be positioned individually on the relevant workpiece geometry, Roemheld FSS clamping fixtures allow for a flexible configuration of individual surfaces when clamping and supporting workpieces. The Roemheld Kostyrka UHF clamping and support elements consist of a guided and axially adjustable piston rod that can be clamped into any position by using a Kostyrka clamping sleeve. This procedure, and the clamping of the piston rods, are both fully automated.

A vacuum pad with internal ball location that provides a defined contact surface is used as an interface to the workpiece. Depending on the workpiece surfaces and geometry, with the appropriate vacuum pads, it is possible to obtain clamping forces of a minimum of 300N for each UHF element. As well as having multiple applications within the aerospace sector, this system can also be used across automotive, rail, boat-building and space technologies.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
