Definitions
- the invention relates to a device for fastening a roller ring on the freely projecting end of a cantilevered roller shaft, consisting of two pressure rings axially clamping the roller ring between them, one of which is axially supported on the roller shaft and the other on a clamping device, from one by means of an actuator axially displaceable wedge sleeve between the roller ring and the conical roller shaft in the area of the roller ring and from a carrier fastened on the roller shaft for the tensioning device and the actuator.
- the free end of the roller shaft carries an end cap with an external thread for receiving a pretensioning nut, with the aid of which the rolling ring made of hard metal and made of hard metal for the production of profile wires is made between two pressure rings is subjected to an axial pressure bias.
- a radial prestress is sought, with the aid of a wedge sleeve between the rolling ring and the conical roller shaft in the area of the rolling ring. This wedge sleeve is driven into the annular gap between the rolling ring and the conical part of the roller shaft by means of adjusting screws which are held in the end cap and are distributed over the circumference.
- This prestressing of the roller ring serves on the one hand to ensure a sufficient frictional connection for the torque transmission from the rollers shaft on the rolling ring and, on the other hand, reduces the notch effects and loads occurring in the area of the rolling ring during the rolling process. Since, due to the tension sensitivity of the hard metal rolling rings, exceeding the permissible ring prestress leads directly to an increase in the risk of breakage, however, the prestressing of the rolling rings is aimed at in the range of the permissible limit value in order to be able to ensure that the rolling rings are securely rotated even in the event of shock loads Adjustment of the preloads in both the axial and radial directions is required, independently of one another.
- the invention is therefore based on the object to avoid these deficiencies and to improve a device of the type described so that the rolling ring can be biased easily and precisely in the axial direction and independently of it in the radial direction without complex manual labor, whereby by the constructive design of the clamping device for the two pressure rings and the actuator for the wedge sleeve the interchangeability of the rolling ring should not be affected.
- the invention achieves the stated object in that the pressure ring on the side of the tensioning device has circumferentially distributed passage guides for axial pressure tappets provided between the wedge sleeve and its actuator, and in that the tensioning device and the actuator each consist of a piston drive which can be acted upon separately by a hydraulic medium .
- the design of the tensioning device and the actuating drive as piston drives which can be acted upon separately ensures first an accurate and simple preloading of the rolling ring in the axial and radial directions via the respective application pressure, whereby not only a compensation of different thermal expansions, but also of thermal stresses occurring during the rolling process is possible becomes.
- This independent application of the one hand the clamping device associated with the pressure ring and on the other hand the wedge sleeve is achieved without an undesired extension of the wedge sleeve beyond the pressure ring by the provision of axial pressure plungers between the wedge sleeve and its actuator which penetrate the pressure ring in corresponding passage guides and can therefore be acted upon from the carrier side .
- the pressure tappet held in the pressure ring for loading the wedge sleeve provides a structural unit which considerably simplifies the replacement of the rolling ring, because after the removal of this pressure ring, both the wedge sleeve and the rolling ring are freely accessible.
- the pressure tappet for adjusting the wedge sleeve and the pressure ring receiving the pressure tappet can be acted upon by hydraulic cylinders arranged in corresponding partial circles.
- the two piston drives consist of two concentric annular pistons which are inserted into concentric annular grooves in the carrier, which form the annular cylinder space for the annular pistons and are connected to corresponding hydraulic lines.
- the carrier receiving the ring pistons can be connected to the roller shaft by means of fastening screws.
- the carrier for the two piston drives it is more advantageous to design the carrier for the two piston drives as an end nut that can be screwed onto the roller shaft, because such a construction not only makes it easier to remove the carrier from the roller shaft, but also enables tolerance compensation for the positioning of the piston drives on the associated structural parts .
- the screw adjustment of the end nut makes it possible to adjust the position axially, with the hydraulic clamping devices eliminating the need for a fixed axial position of the end nut.
- the pressure tappet between the wedge sleeve and its actuator in a further embodiment of the invention is slidably mounted in the passage guides of the pressure ring, then this assembly is particularly easy to use because the pressure tappet is held captively in the passage guides.
- the pressure tappets on the piston drive side can have a head projecting above the passage guides, the heads of the pressure tappets being covered by a pressure transmission ring which can be moved axially within the pressure ring and can be acted upon by the piston drive for the wedge sleeve, so that the pressure tappet heads prevent the pressure tappet from falling out of the passage guides in the pressure ring on one side and the pressure transmission ring prevent the pressure plunger from falling out on the other side.
- the possibility of axial displacement of the pressure transmission ring relative to the pressure ring is absolutely necessary for the independent application of the wedge sleeve and the pressure ring.
- the roller shaft 1 which is mounted on the fly in the usual way, carries in the region of its freely projecting end 2 a rolling ring 3 made of hard metal with corresponding rolling calibres 4 for the production of profile wires or rod-shaped profiles. Between this rolling ring 3 and the roller shaft 1, which has a conical section 5 in the area of the rolling ring 3, a wedge sleeve 7 is provided with axial slots 6, which on the one hand ensures centering and on the other hand ensures radial prestressing of the rolling ring 3.
- This wedge sleeve 7 forms an annular shoulder 8, act on the pressure ram 9 distributed over the circumference, which through a an annular piston 10 formed actuator can be acted upon in order to drive the wedge sleeve 7 with a predetermined force into the annular gap between the roller shaft 1 and the roller ring 3.
- the axial holding of the rolling ring 3 takes place between two pressure rings 11 and 12, of which one pressure ring 11 is supported on a shaft shoulder 13, while the other pressure ring 12 is connected to a tensioning device formed by an annular piston 14.
- the arrangement is such that the ring pistons 10 and 14, which can be acted upon separately from one another, are inserted into two concentric ring grooves 15 and 16 of a carrier 17 fastened on the roller shaft end 2, which is designed as a screw-on end nut 18.
- the pressure rams 9 for the axial application of the wedge sleeve 7 in the guide guides 19 of the pressure ring 12 are slidably held in a stop-limited manner because they have a head 20 projecting beyond the passage guides 19 which is axially displaceable in the pressure ring 12 by a stop-limited pressure transmission ring 21 is covered.
- the latter is provided with a circumferential groove 22 into which stop screws 23 distributed in the circumference and held in the pressure ring 12 engage.
- the rolling ring 3 can be preloaded independently of one another in the radial and in the axial direction, because the annular pistons 10 and 14 act independently of one another on the pressure ring 12 and the pressure transmission ring 21, specifically with a preselectable application pressure.
- a friction ring 24 is provided between the pressure ring 12 and the roller ring 3, which, with a corresponding axial contact pressure for the desired frictional connection between the pressure ring 12 and the rolling ring 3 provides.
- a prerequisite for the desired torque transmission is that there is a rotationally fixed connection between the pressure ring 12 and the end 2 of the roller shaft 1.
- a multi-groove connection 25 can be provided between the pressure ring 12 and the roller shaft 1.
- the spline sleeve 7 can also be mounted in a rotationally fixed but axially displaceable manner on the shaft end 2 via a multi-slot connection 26, the connection ring 8 being particularly recommended for the arrangement of this multi-slot connection.
- the pressure plunger 9 passing through the pressure ring 12 does not hinder these multi-groove connections.
- the wedge sleeve 7 is made of a friction material, for example a fiber-reinforced polyamide, then a considerable proportion of the torque can also be transmitted to the rolling ring 3 via the wedge sleeve 7 without fear of exceeding the permissible radial preload of the rolling ring 3.
- a friction material for example a fiber-reinforced polyamide
- the construction according to the invention for the independent hydraulic loading of the pressure ring 12 on the one hand and the wedge sleeve 7 on the other hand is of course not restricted to a device with an interposed friction ring and a multi-groove connection between the roller shaft and the pressure ring or the wedge sleeve. Rather, it can be used in all generic devices in which a precise adjustment of the axial and radial preload of the rolling ring is required to match the rolling ring load and the transmissible torque.
