Definitions
- the invention relates to a rolling tool with at least one roller roller rotatably mounted, guided and supported on a roller head.
- the roller can also be a ball.
- the rolling roller is not designed as a ball but as a roller, it can also be pivoted and also adjustable in its pivoting angle. The pivoting can also be achieved by a corresponding pivoting of the roller head.
- Rolling tools of the type described above are generally in use in the form of smooth rolling tools and have proven themselves well. You will e.g. used on center lathes for the smooth rolling of turned parts. Depending on requirements, such a tool is manually clamped on the machine support by the operator and, after use, again clamped due to the significant space requirement. The tools are large, have a relatively large number of individual parts and are expensive to manufacture.
- the object of the invention is to propose a rolling tool of the type described in the introduction, in which the size for the roller head is further reduced and the influence of the inertia of the support rollers is eliminated.
- roller head is designed as a hydrostatic bearing for the roller and has a connection channel for a connection to a pressure source for a fluid.
- the hydrostatic bearing of the roller ensures that the Herz pressure that has hitherto occurred between the roller and the support roller and the resulting pitting is completely avoided.
- the service life of the corresponding components can thus be significantly increased.
- the service life and thus the economy of such a tool can be improved by using roller rolls made of ceramic materials.
- Figures 1 and 2 show a rolling tool, for example for the smooth rolling of surfaces on turned parts, preferably of cylindrical outer surfaces.
- This rolling tool can be clamped with the housing 1 in a tool carrier, not shown, of a lathe, for example an NC lathe, or also in a turret, not shown, of a tip lathe.
- a rolling roller 2 which is mounted in a hydrostatic bearing 3 and secured against coming out, is pressed with a rolling force F against the surface of the workpiece 11 to be smoothed.
- the rolling force F is absorbed by the roller head 4, which essentially consists of the roller 2 and the hydrostatic bearing 3 of the roller 2, and via a plunger which is guided in the housing 1 and the associated cover 14.
- the rolling force F is generated by the pressurized fluid required for the hydrostatic bearing.
- a pressure source not shown, is connected to the connection 6 and the fluid flows through the channel 8 in the direction of the arrow 7 and enters the hydrostatic bearing 3 and forms a pressure cushion between the bearing shell 9 and the roller 2.
- the roller 2 does not necessarily have to be a roller, but can also be a ball.
- the plunger cross section 10 is acted upon by the fluid. Under the pressure of the fluid on the roller 2 and the plunger 5, the roller head 4 moves in the direction of the workpiece 11 and the roller 2 is pressed against the workpiece 11 and for the Forces intended for smooth rolling build up. The fluid flows through the rolling tool and a steady flow is formed.
- the fluid emerging at the hydrostatic bearing 3 is drained from the roller head 4 via the relief channels 12 and used for the lubrication of the rolling process.
- the rolling force F is determined by the surface 13 acted upon by the pressure of the fluid on the rolling roller 2.
- the plunger 5 is received and axially guided by a bore 68 made concentrically in the cover 14 of the housing 1. Between the bore 68 and the cover 14, a seal 69 is provided for sealing the annular gap 70 in order to prevent the fluid from escaping between the plunger 5 and the cover 14.
- the cover 14 is connected to the housing 1 with a thread 71 and at the same time fixes a stop 16 located in the housing 1 in a guide bore 72.
- a seal 73 is again provided.
- a further guide for the plunger 5 is provided, which is formed in that a guide disk 15 is fastened on the plunger 5 with a thread 74.
- This guide disk 15 guides the plunger 5 in the guide bore 72 of the housing 1 and at the same time serves as a stroke limiter with the stops 17 and 16.
- the guide disk 15 is provided with overflow bores 75.
- the rolling tool according to Figure 2 is additionally equipped with a return spring 18 which is clamped between the stop 16 and the guide disk 15 with the aid of the cover 14 and the housing 1, with the aid of which the roller head 4 or the plunger 5 is in a starting position, such as shown, can be retrieved.
- a return spring 18 When using a return spring 18, the plunger cross section 10 is designed to be larger than the surface 13 of the hydrostatic bearing 3, so that the sum of all forces is again zero.
- the roller 2 has so much play in the hydrostatic bearing 3 in the direction of the workpiece 11 that the roller 2 is free of the holding parts 19 when the pressure pad is formed when the roller 2 is in contact with the workpiece 11.
- the housing 1 can be provided in a multiple arrangement on a clamping shaft 83.
- the clamping shank 83 can, if desired, also be arranged so as to be rotatable about the axis 87.
- FIG. 3 shows a rolling tool which is equipped with a throttle 20 to influence the pressure.
- This throttle 20 is arranged at the entrance to the channel 8 of the plunger 5 and a further throttle 21 is formed by the hydrostatic bearing 3 itself.
- the inlet pressure p1 in the chamber 22 is throttled to the pressure p2 in channel 8, so that the pressure p2 is available for the generation of the rolling force. Since the pressure p1 is higher than the pressure p2, an excess force is available at the plunger 5, which makes it possible to provide a return spring 18.
- the return spring should have as flat a characteristic as possible.
- FIG. 4 shows a tool in which a throttle for determining the pressure p2 is instead arranged on the roller head 4 instead of on the plunger.
- the throttle 23 is designed as an adjustable throttle.
- the cross section of the bore 24 is narrowed or expanded by the throttle needle 25.
- the throttle needle 25, which is designed as a screw, extends with its needle tip into the bore 24 and limits the free cross section of the bore 24.
- the throttle needle 25 is axially displaced in the bore 24 with the aid of the thread.
- the throttling needle is secured against adjustment of the set flow cross section with the lock nut 26.
- a seal 69 installed under the lock nut 26 seals the throttling needle against leakage of fluid.
- FIG. 5 also shows a rolling tool for smooth rolling surfaces on turned parts.
- This rolling tool can be clamped with the housing 28 in a tool carrier or turret, not shown, of an NC lathe or tip lathe.
- the rolling roller 2, which is mounted in the hydrostatic bearing 3 and secured against coming out, is pressed with a rolling force F against the surface of the workpiece 29 to be rolled.
- the rolling force F is absorbed by the roller head 30, which is formed at the end facing away from the roller 2 as a piston 31, which is received by the cylinder 32 of the housing 28.
- the hydrostatic bearing 3 is supplied with fluid separately from the housing 34.
- the housing 34 is supplied with pressure medium via the connection 35.
- the housing 28 Against the force of the return springs 36 which are in a bore 79 the housing 28 are housed, on the one hand abut the housing 28 and on the other hand by a thrust washer 80 with nut 81, which sit on the threaded pin 78, which penetrates the return springs 36 axially, the roller head 30 when the housing 34 is pressed by the connection 35 with Pressure medium pressed against the workpiece 29.
- the hydrostatic bearing 3 is activated by loading fluid through the connection 33.
- the force of the housing 34 and the force on the hydrostatic bearing must be balanced during rolling so that the hydrostatic bearing is functional and the desired rolling force is also generated.
- FIG. 6 shows a tool similar to FIG. 5.
- the housing 28 designed as a fluid cylinder of the design according to FIG. 5 is now replaced by a housing 39 in which a spring assembly 38 is arranged.
- this spring assembly is composed of disc springs. However, it could also be a spiral compression spring.
- the springs of the spring assembly 38 are arranged in a suitable bore in the housing 39 and press against the rear of the shaft 41 of the roller head 40. This shaft 41 is guided in the housing 39.
- the springs of the spring assembly are supported against the end of the bore of the housing 39 in which they are installed.
- the shaft 41 of the roller head 40 is extended by a pin 42, which extends in a bore 46 of the housing 39.
- this pin 42 has an elongated hole 43.
- This slot 43 is penetrated by a pin 44.
- the pin 44 is in turn received by a bore 45 which is located in the housing 39.
- This tool is positioned in that it is clamped in the processing machine and pressed with the roller 2 against a workpiece 29 and thus tension the springs 38 to the intended rolling force.
- the shaft 41 with the connected pin 42 moves relative to the housing 39.
- the hydrostatic bearing 3 is charged with fluid via the connection 47 and thus activated.
- the springs must be balanced with the fluid force on the hydrostatic bearing 3.
- the springs need not be disc springs, as shown in FIG. 6.
- coil springs are not the only alternative, but it can also be used, for example, two rod springs arranged at a distance and parallel to each other, which connect the clamping shaft and the roller head so that they can move relative to each other against the bending force of the rod springs.
- FIG. 1 A particularly simple tool is shown in FIG.
- the clamping shaft 48 and the roller head 49 are a structural unit, so that a relative movement between the two parts mentioned is not possible.
- the clamping means which accommodate such a tool, do not permit a corresponding radial movement
- the total possible radial movement of the roller 2 is determined by the play 50 of the roller 2.
- the roller 2 When placing the tool on the workpiece 51, the roller 2 must be positioned so that it rests on the workpiece 51, but has 19 play to the bearing shell 52 and the holding parts.
- the hydrostatic bearing 3 is activated, the rolling roller 2 is pressed against the workpiece 51 and the rolling force is thus generated.
- FIG. 7A shows a tool which is almost the same as the tool according to FIG. 7, in which only the connection 47 is placed downward at the end of the clamping shank 48.
- FIG. 8 now shows a rolling tool in which the formation of a rolling roller 53 can be clearly seen.
- the roller 53 is in turn guided hydrostatically in a roller head 58.
- the roller head 58 is slidably guided in a pocket 61 of a housing 60.
- a return spring 82 is arranged as a tension spring between roller head 58 and housing 60.
- the roller head 58 also has a plunger 59 which is guided in a corresponding bore 88 of the housing 60 in a manner which has already been described.
- the plunger 59 has an inner connection channel 84 which is connected to the bore 88 via a throttle 20.
- the bore 88 can be supplied with pressure medium via the connection 85.
- the sectional representations according to FIGS. 9 and 11 show the formation of the hydrostatic bearing of the roller 53.
- a bearing shell 54 of the shape 55 is formed, within which the pressure of the fluid builds up and the roller 53 carries.
- the overflowing fluid is discharged via the relief channels 66.
- the corresponding rolling force is built up via the contact surface 57 between the workpiece 56 and the roller 53, which force is kept in equilibrium by the pressure of the fluid. If this balance were not present, the surface of the roller 53 would lie on the upper edge of the mold 55. In the case of equilibrium, however, it does not rest there, so that a small gap can emerge from the fluid which, as said, is then continued via the relief channels 66.
- the shape 55 of the bearing shell 54 corresponds to the shape of the contact surface 57 between the roller 53 and the workpiece 56.
- the section CD according to FIG. 10 shows a stroke limitation of the roller head 58.
- the roller head 58 itself has a groove 62 on the side into which a threaded pin 63 protrudes, which in a corresponding one Thread of the housing 60 is movable. However, it is screwed in only once so that the pin (not shown) protrudes into the groove 62.
- the pin projecting into the groove 62 enables the roller head 58 to move about the stroke 64, which is limited by the upper and lower stops 65 coming into contact with the pin.
- FIG. 12 shows a diagram with a curve for laminar flow and turbulent flow, in which the ratio of the inlet pressure to the pressure of the pressure chamber for the hydrostatic support of the roller is plotted on the ordinate and the ratio of the throttle areas on the abscissa.
- the diagram speaks for itself and requires no further explanation.
- the sequence of a smooth rolling process with a rolling tool according to FIG. 3 will be explained below.
- the rolling tool is accommodated with the housing 1 in a tool carrier of a lathe, not shown.
- a workpiece 11 is clamped in the chuck of the lathe and the chuck drive is switched on, so that the workpiece 11 rotates.
- the rolling tool is moved with the tool carrier to the section of the workpiece to be smoothly rolled until the rolling roller 2 is approximately half the roller head stroke 64 away from the workpiece.
- the fluid of the hydrostatic bearing is fed under pressure p1 through the connection 6 into the chamber 22 and flows through the throttle 20 into the channel 8 and builds up the pressure p2 here.
- the fluid flows to the throttle 21 and the hydrostatic bearing 3 is activated.
- the roller head is pushed against the workpiece 11 by the fluid pressure and the roller roller 2 is pressed against the workpiece 1.
- the hydrostatic bearing 3 is now active and the roller 2 rotates, driven by the workpiece 11.
- the longitudinal feed of the tool carrier can now be initiated and the rolling process can be carried out in the usual way. If the section of the workpiece to be rolled has deviations from the cylindrical shape, then the roller head 4 with the roller 2 can follow such a deviation. If the fed pressure p1 is reduced below the working pressure, the roller head 4 is the return spring 18 is lifted off the workpiece.
- FIGS. 13 to 16 show a simple tool which corresponds in its essential structure to the tool already described according to FIGS. 7 and 7A.
- the design of a tool according to FIGS. 13 to 16 has changed.
- This change allows, for the first time in hydrostatic bearings, a relatively large stroke movement of the rolling rollers, which are thus able to avoid relatively large dimensional inaccuracies of the workpiece without the rolling force being influenced to any appreciable extent.
- this is because, in one embodiment of the tool or the hydrostatic bearing of the roller 2 according to FIGS. 13 to 16, the throttle gap for the pressure oil of the hydrostatic bearing is not changed by the lifting movement of the roller, with the exception of the outer end position.
- the tool according to FIGS. 13 to 16 has a clamping shank 48 already described there, which has a pressure oil connection 47.
- a channel 92 connected to the pressure oil connection 47 and having the flow cross section 93 directs the pressure oil into a guide chamber 90, which is designed as a cylinder 91 in the exemplary embodiment.
- the roller 2 is designed as a ball with a ball diameter such that the roller 2 designed as a ball only fits into the cylinder 91 while leaving a throttle gap 95 between the surface of the ball and the walls 99 of the cylinder 91.
- the cylinder 91 is open and has an enlarged area 101 there.
- This widened area is further connected to the outside by a narrowed area 103 formed by inclined surfaces 102, so that this narrowed area 103 forms an outwardly open cross section 104 on the holding part 19, which is smaller than the cross section, on the holding part 19 105 of the guide chamber 90.
- Relief channels 12 are provided within the overall area of expansion and narrowing.
- FIGS. 17 and 18 A possible tool design is shown in FIGS. 17 and 18. These tools make use of the formation of the hydrostatic bearing of the roller head 106.
- the guide chamber 90 already described, with a roller 2 arranged therein, as in FIGS. 13 to 16 described, provided and arranged in a multiple arrangement and uniform distribution on a cylindrical base body 97.
- the cylindrical base body can be designed as a hollow body, which comprises a workpiece to be machined, or, conversely, can be designed in the manner of a cylindrical mandrel, as is shown in FIGS. 17 and 18.
- the guide chambers 90 are each directed radially and embedded in the cylindrical base body, each with a roller roller 2 arranged therein. All guide chambers 90 are in turn supplied with pressure medium via a channel 92.
- roller head 106 ' which can comprise a workpiece or, as the design according to FIGS. 17 and 18 shows, can be inserted or inserted into the bore of a workpiece for machining the bore surface.
- the pressurization of the rolling rollers 2 can take place before the tool enters the bore of the workpiece, so that the bore wall of the workpiece presses the roller rollers back into the guide chambers 90 during the entry phase to such an extent that the pressure medium supply quantity or other suitable measures are given there Pressure fluid pressure and thus the assigned rolling force.
- the tool or the workpiece or both can already be rotating, or the rotational movement of the parts mentioned can also only be started at the time when the rolling rollers 2 come into contact with the workpiece surface.
- Such a rolling tool of the type according to the invention with a hydrostatically guided roller has many advantages.
- the tool is very small and can be used like any other cutting tool in a turret head of corresponding processing machines and can remain there. It can be attached to the workpiece while the workpiece is running, so that the previously required workpiece standstill for applying the smooth rolling tools is no longer necessary.
- the rolling rolls have a much longer service life than before, since the pitting does not occur due to the interaction with the previously required support rolls. This advantage is further improved when using roller rolls made of ceramic materials.
