Clamping Levers

Elesa permanent magnets offer a simple way of providing temporary fixing for workpieces, instruments, gauges, covers, doors, signs or drawers. They offer a range of closure from low to extremely high adhesive force in a very small footprint − giving easy manual placement or concealed closure if required. Temporary fixing with high power magnets can provide permanent solutions, quickly adjusted or removed completely.

For example, Elesa’s range of high quality permanent magnets in sintered hard ferrite, Aluminium nickel cobalt (AINiCo), Samarium cobalt (SmCo) and Neodymium iron boron (NdFeB) are structured to have one adhesive surface only with poles optimized and arranged in such a way that the whole magnetic energy is focused on the adhesive surface. The effect in the area of the magnetic field is limited by a shielded system, avoiding the magnetization of the surrounding objects.

Neodymium magnets are ideal for location and temporary fixing of workpieces or panels or for sensor holding, e.g. on conveyors or other machinery. Moving down the scale applications can be as varied as supermarket labelling, locating presentation materials, white boards, cabinet door closure or magnetic filtration, e.g. of metal particles in engine sumps or in machinery and equipment.

These high quality permanent magnets are available in flat format with or without, steel or stainless steel housings in lacquer or thermoplastic coating and in cylinder format with brass housed sandwich configuration. U Magnets and cylinder magnets in red lacquer with pass-through facility are also part of the standard series.

Indexing plungers, spring plungers and quick release pins for industrial applications from Elesa UK. Indexing plungers are available in black-oxide steel, stainless steel or SUPER-Technopolymer and they are widely used in cases of repetitive indexing of elements to be machined. Locking pins are ideal for quick positioning of components, especially when they need to be continuously removed and repositioned. The high quality and the variety of the materials used for their production and the variety of shapes, sizes and standard executions allows us to offer you a particularly wide range.

Indexing and positioning elements from Elesa include:
- indexing plungers
- lever indexing plungers
- safety indexing plungers
- mini indexing plungers
- mounting flanges
- positioning flanges
- positioning boss
- ball lock pins
- lock pins
- ball chains
- retaining cables
- spiral retaining cables
- threaded spring elements
- threaded ball spring plungers
- threaded bolt spring plungers

Machine change-over time in production is a key issue affecting the operation of packaging lines and can often present a critical bottleneck. The challenge for Elesa was to reduce the time taken for machine switchovers on packaging lines installed on site at their end users.

Explained Nigel Pritchett MD at Elesa (UK) “machine downtime for our customers and their end-users can become a major problem while they re-set each roller spindle manually. Fortunately, we have a solution readily available in the form of our unique wireless digital electronic positioning system.”

“These units are a like-for-like replacement for conventional items and the connected system allows up to 36 position indicators to be re-set all together from a PC link. This saves a great deal of time compared to re-setting each one individually for different packaging configurations.”

Elesa’s RF electronic positioning indicators are unique in the market, enabling wireless communication with a PLC. This results in faster, more efficient machine set-up and associated change over processes. The wireless system enables a quicker and more reliable machine set up - achieved by the use of a linked controller, which displays the initial set-up values on each of the electronic position indicators.

An operator can simply choose the appropriate menu, then quickly re-set each spindle to its correct start position and the machine is “good to go”. This saves large amounts of time and greatly reduces the possibility of human error every time the line is changed or recalibrated.

This flexibility enables the Elesa system to be adapted as a mainstream option on all such machines and ensures it may be retrofitted to existing installations when upgrading a complete facility.
