Definitions
- the prior art shows examples of solving the self-locking effect of expansion elements by inducing vibrations.
- the foreign document DE 21 63 976 A1 shows a method for reducing the friction between a thread and thread guide parts of textile machines.
- the thread has been tangentially wound onto a drum and withdrawn axially from the drum by a brake ring, which consists of a drum surrounding the drum at a distance base ring and extending from this to Spei ⁇ drum surface elastically, individually distributed over the base ring circumference with intermediate intervals Fingers which extend inwardly from the base ring along an imaginary conical surface and, in the sense of the relative circulation of the thread around the drum, are arranged so as to overlap one another in the circumferential direction and are aligned with their free ends. ner shoulder of the drum are supported, so that vibrations are generated in the thread when sliding over the fingers.
- the document JP 60244764 A discloses a device for inserting and holding an empty bobbin between a carrier and a handle.
- the handle of the carrier is pushed down by a drive to bring the empty spool into contact with a friction roller.
- a vibration generated in this case is determined by a vibration detector, the detector being arranged on the carrier arm.
- the vibration detector is connected to a vibration-shape comparator in order to compare the amplitude at time A and B with a predetermined reference amplitude. In this way, it can be determined whether or not the empty spool is fixedly installed on the support arm.
- the document DE 2 223 195 A1 describes a method and a device for the non-thermal release of mechanical connections.
- one of the connected parts is subjected to mechanical vibrations in the frequency range of the ultrasound until the connection is released.
- It is a Traumspann ⁇ device for clamping at least one of a plate to be solved element provided.
- the jig is firmly seated on a cone-shaped mandrel whose other end for vibration transmission is fixedly connected to an amplitude-controllable mechanical transmitter operating in the frequency range of the ultrasound.
- the object of the invention is to provide a method and a device which are suitable for relieving the reel mandrel, which is hydraulically tensioned by internal wedge surfaces, during reeling of cold rolled strip to such an extent that the clamping segments return to the initial position slip back and thus loosen or cancel the Dishemmungsef ⁇ effect and virtually trouble-free removal of the coils from the mandrel under comparatively straightforward and inexpensive means er ⁇ possible.
- the method according to the invention provides that the self-locking effect of the expansion elements is at least partially or completely canceled by applying longitudinal vibrations acting in the axial direction.
- the device according to the invention provides that a vibrator is attached to the end face of the hutch mandrel.
- the vibrator is supplied via a rotary feeder or a quick-closing coupling to the excitation compressed air.
- a pneumatic turbine vibrator or a pneumatic impact vibrator can be used as vibrators.
- FIG. 1 shows in the diagram the course of friction forces with and without vibration, the progression of weight forces as a function of the tensile forces, and the course of vibration forces in relation to the adhesive or sliding forces that occur therewith.
- FIG. 2 shows a coiler mandrel in the section of a median plane with the vibrator placed on the end.
- 3 shows in section a rotary feeder for compressed air for driving the vibrator V which is mounted in the longitudinal direction.
- the curve A static friction
- the traction only increases by 30 N.
- FIG. 2 shows a coiler mandrel 1 in the half-open state. It shows on each side a number of four wedge surfaces S in the present case, which cause a self-locking effect when the dome moves axially.
- a vibrator V is mounted on the front side 2 of the coiler mandrel 1.
- a pneumatic impact vibrator 1 is preferably ver ⁇ used. Whose vibration sets the friction between the wedge surfaces S of the spreading so far down that the coiler mandrel 1 is released from the wrap of the coiled band and the spreading collapse irrespective of their lubrication state and release the coil.
- the vibrator V shown in section in Figure 3 has a housing 1 'with a terminal flange 9, with which it is fixedly connected to the reel shaft 4 of the reel mandrel 1 by means of a screw connection.
- it is a pneumatic impact vibrator for generating longitudinal impact pulses. Its function is similar to that of a so-called compressed air hammer, whereby a tool loosely guided in the housing, such as a hammer, is rocked back and forth by exposure to air.
- the vibrator comprises a flying piston 2 with intersecting edges for interaction.
- the interior of the vibrator 1 is closed with the lid 3. At this there is a valve assembly 5, 6, 7, which can be opened or closed in order to initiate the impact work of the impactor 2.
- Compressed air flows from the supply channel 8 through the body of the vibrator 1 and escapes after excitement of the impactor 2, as indicated in the drawing, through an opening of the valve 6 in the free atmosphere.
- the inventive method and the corresponding device solve in an ideal way the task.
