How does a refrigerator work?
Every household today has a refrigerator, so that food can be kept longer and does not spoil so quickly.
You may not have asked yourself how such a device works - but the answer is really interesting: A refrigerator does not actually cool, contrary to what is usually assumed, but it extracts heat from the interior.
Nowadays, the cooling mechanism works economically and effectively: Refrigerators manage temperatures between 5 and 9 degrees Celsius, freezers -15 to -18 degrees Celsius.
We explain below how the clamping technology of EMUGE-FRANKEN contributes its know-how to the manufacture of refrigeration pumps for refrigerators.
At the centre: Refrigeration pump and coolant
The volume of today's refrigerators has reached considerable dimensions and is well over 300 litres for large floor-standing appliances. A closed cooling circuit ensures that the interior is sufficiently cooled. The coolant and the cooling compressor or the cooling pump are the central elements.
The refrigerant is a special liquid which flows through pipes inside the refrigerator and absorbs heat. The liquid flows through a grate attached to the outside at the rear outer wall of the refrigerator. Here, the liquid releases the absorbed heat. The cooling pump ensures circulation of the coolant. When a refrigerator starts to "hum", it means that the refrigeration pump is working. This does not happen continuously, but efficiently and according to the set temperature.
A side effect: The refrigerator heats the kitchen with the heat it gives off.
The clamping technology department of EMUGE-FRANKEN has developed a clamping concept with which the crankshafts of refrigeration compressors and pumps are clamped for the machining operation.
One clamping tool for different lengths of workpieces
The clamping diameters of all workpieces are the same, the eccentric dimensions differ, as do the workpiece lengths.
The challenge for us: The customer nevertheless wants to clamp the workpieces with a clamping device.
Our staff developed the following clamping concept for this:
The workpiece is held by a collet in a clamping device. The clamping is initiated via the pull rod on the machine side and the internal tension and pressure piece of the clamping device. The clamping concept also provides for the use of interchangeable fixtures for the various workpiece dimensions.
The added value for the customer: Interchangeable centring inserts enable the machining of several workpieces with different eccentric dimensions and workpiece lengths on one clamping device - with consistent quality and adherence to tolerances.
Clamping technology and everyday objects
The question is: how does the clamping technology of EMUGE-FRANKEN and the production of an everyday object fit together?
We would then be happy to recommend our other success stories to you.
Here you will learn briefly, concisely and vividly about the workpieces that the clamping technology of EMUGE-FRANKEN can clamp. These include workpieces with reference to cars or aeroplanes, but also everyday objects such as watch cases and rings. - the range is enormous!
