- the movement of bit which is proportional to the displacement of the body of cylinder 18 can also be measured and recorded using the displacement sensor 43.
- the crimping operation is thus perfectly controlled.
- the efforts and displacements necessary for the implementation of a good crimp quality depend on different parameters related to elements of the fitting to be made. These parameters are in particular relating to the malleability of the outer ring metallic crimp which characterizes the ability to deform plastic of the outer ring during crimping, the structure of the flexible connector to be assembled, the thickness and variations in thickness of flexible conduits depending on the manufacturing technique of the conduits flexible, for example by extrusion and with characteristics of compression of the material constituting the flexible conduit.
- the displacement sensor 43 makes it possible to determine the position of the cylinder body 18 at the end of the stroke crimping.

- the cylinder body 18 returns then forward and the jaws 27a and 27b are recalled in radial directions outward by the devices return bands 31.
- the displacement sensor allows you to check whether the correlation force and displacement is correct compared to the results obtained during the development.
- the assembled fitting is ejected, preferably from automatically, through the front of the device crimp 10.
- the crimping device is ready for operation following crimping which can be performed from the as described above.
- This change can be made very quick by dismantling the actuating part 14 by simple unscrewing the connecting screws to the front part 18c of the cylinder body 18.
- the crimping block 12 can then be extracted by simple pull in the axial direction 36, insofar as the key 35 is slidingly mounted in groove 34 ensuring retention in rotation of the support 26.
- a replacement crimp block suitable for new part dimensions is then introduced in the device 10, so that its groove 34 comes to engage on the key 35 of the cylinder rod 15.
- the nut sleeve 20 is replaced by screwing inside the bore of the cylinder rod 15 and on the threaded part of the support 26 of the crimping block of substitution.
- the annular actuating means 14 is then replaced and fixed by screws on the end part front of the cylinder body 18.
- the device according to the invention therefore allows a very rapid adaptation to manufacturing concerning pieces of different diameters.
- this device has a very large precision and allows crimping in perfectly defined conditions, to ensure characteristics wanted crimped parts.
