Definitions

  • the invention relates to a method and a device for copy grinding and smoothing cylindrical and spherical surfaces according to the preamble of claims 1 and 2 respectively.
  • wheel grinding devices are used in which the course of the curved surface is carried out via a grinding wheel controlled by a cam wheel.
  • a grinding wheel In the case of such a grinding wheel, the grinding wheel resting with its edge on the cylinder surface cannot avoid grooves on the machined cylinder surface. If there is more wear, the surface will also have to be over-rotated, while leveling and fine grinding will then have to be carried out.
  • a device of this type is known from DE-OS 36 39 264.
  • a support is provided between two brackets arranged on columns, and an adjustable copying template designed as a guideway and corresponding to the desired value of the spherical surface accuracy is provided.
  • An abrasive belt device with an abrasive belt drive, an infeed slide with adjusting devices with axially movable guide bushings and a tensioning device are arranged on the copying template and the carrier.
  • cylinders are heated, different radiation conditions arise between machined and non-machined cylinder surfaces, which lead to heat differences in the cylinder wall, where different expansions arise between machined and non-machined partial surfaces.
  • the invention has for its object to avoid such large differences in expansion between the protruding and the smoother worn cylinder part surfaces in order to achieve higher machining precision and to enable shorter grinding times with less material removal and thereby longer overall service life of the cylinders.
  • An advantage of the method according to the invention is, in particular, that the grinding with the subsequent fine grinding is preceded by a grinding phase in which the grinding belt is pressed against the outer surface of the cylinder under a predetermined pressure within a play that can be set between the copying template and the contact roller, so that the Cylinder surface is removed evenly regardless of its geometry.
  • This also ensures a uniform heat distribution and thus also a uniform expansion of the cylinder surface, which is particularly important in the radial direction, as a result of which a more precise cylinder geometry is achieved.
  • the carrier is shielded from the cylinder surface to be machined with a special heating plate, which prevents deformation of the carrier, which leads to higher precision of the machining cylinder and the time-consuming preheating of the grinding device, which would otherwise be necessary, is unnecessary.
  • 9 denotes a machine frame, on which brackets 2 are provided for holding a carrier 4 arranged on a base plate 3.
  • a guide track 7, which interacts with a support roller 8, and a copying template 10 are arranged on the carrier 4.
  • Supports 11 with receptacles 12 are displaceably arranged on the carrier 4 at uniform intervals from one another, the copying template 10 being mounted in the supports 11 (only shown in cross section in FIG. 1).
  • Each receptacle 12 has adjusting screws 13 acting on both sides thereof (only indicated with screw axes), through which the copying template 10 can be adjusted over its axial extent according to the predetermined target dimensions, in particular the spherical end parts of the cylinder, so that the copying template 10 has a target contour of a surface to be ground 45 'over the entire cylinder length 45.
  • the carrier 4 is shielded from the cylinder surface 45 to be ground by a heat insulation plate 5 arranged on holders 6.
  • a carrier plate 19 with a displaceable feed carriage 18 slides over the support roller 8 on the guide track 7, the carrier plate 19 receiving movably mounted guide bushes 20.
  • the guide bushes 20 slide on the copying template 10, whereby with the help of a drive motor 14 with gear 15 and a gear 16 and a rack 16 'of the feed carriage 18 with the attached drive motor 24, a drive roller 22 and a contact roller 23 for the grinding belt 21 on the to be ground surface 45 'is guided along.
  • the self-centering of the guide bushes 20 ensures that the contact roller 23 arranged on an adjustable holder 26 is tangential to the cylinder surface 45 in every position, so that a smooth surface can be ground without scoring.
  • the adjustable holder 26 for the contact roller 23 is in connection with the guide bushes 20, whereby an automatic adjustment according to the predetermined sol profile of the copying template 10 with respect to the surface to be ground 45 'takes place.
  • the running position of the grinding belt 21 provided with a protective cover 25 is adjusted via an adjusting screw 28 of the tensioning device 27, which consists of a tensioning cylinder 27 ', a motor rocker and a bearing arranged on the feed carriage 18.
  • the radial feed of the belt grinding contact roller 23 takes place by means of the feed carriage 18, which can be adjusted by an adjusting device 30.
  • a suction device 29 which is formed from a suction nozzle, an intermediate piece and a suction hose, is provided for suctioning off the resulting output.
  • FIG. 3 shows the adjusting device 30, which is attached to the feed carriage 18 via an intermediate piece 38, in greater detail. It is provided with an adjustable stop ring 32 precision spindle 31 which is mounted in a spindle guide 40 and on the spindle side 31 facing away from the contact roller 23 'in bearings 33 which can be clamped by means of a threaded clamping ring 34.
  • a scale (not shown) provided on the intermediate piece 38 of the adjusting device 30 ring 35 which is provided by means of a rubber ring 36 through a sleeve 39 with a handle 39 is taken along and thus an exact delivery of the contact roller 23 to the cylinder surface to be machined 45 'is possible.
  • the ring 35 can generally be adjusted to the O-scale position.
  • An angularly designed threaded ring 37 for setting a game X or X 'between the template 10 and the contact roller 23 is located on the precision spindle 31 below the threaded clamping ring 34, the threaded ring 37' angled to the spindle end 31 'abutting the outer surface of the threaded clamping ring 34.
  • the threaded ring 37 on the spindle 31 is adjusted accordingly relative to the spindle guide 40, so that between the threaded ring 37 and the bearings 33 a game X 'and at the same time correspondingly between the stop ring 32 the bearings 33 a game X is adjustable.
  • a by means of a holder 42 attached to the feed carriage 18 pressure device 43, for example a pneumatic cylinder, wherein a hydraulic cylinder or compression springs could also be used, performs the play movement X or X 'of the precision spindle 31, preferably one shown in dashed lines in Fig.3 Game setting X / 2 X ′ / 2 is set.
  • the cylinder 45 to be machined which has irregular surface wear during operation, for example on a paper machine, and on the outer surface 45 'of which, at elevated temperatures, consists of various particles such as resin, oil, paint residues and the like Surface layer, a so-called coating, has been heated to a certain temperature and brought to a predetermined speed of rotation.
  • a coarse sanding belt 21 is brought to a predetermined running speed by means of an sanding belt drive 22, 23, 24 and in an upstream sanding phase under predetermined pressure the outer surface 45 'of the cylinder 45 to be machined is pressed so that the still irregular cylinder surface 45' is removed evenly regardless of its geometry by a play X or X 'between the copying template 10 and the contact roller 23' is adjusted by an adjusting device 30, as described in detail in the description of FIG. 3, and by the action of the pressure device 43, for example a pneumatic cylinder, during play in the radial direction to the cylinder surface 45 ', a play movement of the contact roller 23 takes place.
  • the pressure device 43 for example a pneumatic cylinder
  • the belt grinder 1 is axially displaced by means of a geared motor 14, 15 on the adjustable copying template 10 in such a way that the entire cylinder surface 45 'to be processed is removed in overlapping grinding belt tracks.
  • a geared motor 14, 15 on the adjustable copying template 10 is axially displaced by means of a geared motor 14, 15 on the adjustable copying template 10 in such a way that the entire cylinder surface 45 'to be processed is removed in overlapping grinding belt tracks.
  • the pressure conditions on the belt grinder 1 are changed such that in a subsequent grinding phase, the actual precision grinding, between the copying template 10 and the contact roller 23, an adjustable feed carriage 18 with the adjusting device 30 is used to adjust the pressure controllable fixed connection arises, as was also said in the description of FIG. 3.
  • the belt grinder 1 runs in back and forth movements, ie in so-called passages, in the axial direction over the entire length of the cylinder 45, with a corresponding fixed infeed of the contact roller 23 to the cylinder surface 45 'being carried out by the adjusting device 30 after each pass.
  • the abrasive belt 21 After the abrasive belt 21 has worn out, the same is replaced with a corresponding infeed of the infeed carriage 18 by the adjusting device 30.
  • the passages with the corresponding infeeds of the belt sander 1 by the adjusting device 30 and the replacement of the abrasive belts 21 are repeated until the cylinder 45 the shape predetermined by the copying template 10 in the axial direction and has an exact roundness.
  • the grinding process is completed by a last grinding phase, in which an exact and correspondingly fine cylinder surface 45 'required in accordance with the manufacturing process is achieved.
  • the device according to the invention is preferably used oil-free, ie as a dry grinding device. However, it is readily possible to use it to carry out a wet grinding known per se.
