Definitions

  • the invention relates to a heatable, for example heatable Roller with a hollow cylindrical, with flange on both sides equipped roller body, which has peripheral, axially parallel heating holes is provided by an axial through holes in the flange pin and between the roller body and its flanges formed cavities supplied thermal transfer medium be flowed through.
  • Such heatable by means of a thermal transmission medium or also coolable rollers are from DE-GM 84 10 839 and 84 36 564 known and widely used.
  • coolable rollers are from DE-GM 84 10 839 and 84 36 564 known and widely used.
  • the heating holes should be relatively close below the lateral surface of the roller body to be accommodated in temperature control to get less inertia, and around the temperature gradient to keep low in the roller body, you have the flanges the flange pin with the tensioning screws connecting the roller body satisfied with cavities of smaller diameter and, if necessary, has laid outwards beyond the cavities Heating holes via separate additional, inclined feed holes connected, so that there is a relatively complex production results.
  • DE-U-90 00 980 also describes a roll that can be temperature-controlled. in which the thermal transmission medium through a flange pin is directed. Through the hollow roller in which there is a displacement body to form a gap, the transmission medium returned.
  • the flange spigot are a variety of radially arranged holes arranged to each heating duct group to lead.
  • such a structure is very much in its manufacture complex and requires a large number of process steps.
  • the invention is based on the object of a heatable calender roll to create the designated genus, in which the manufacturing effort is reduced.
  • Fig. 1 is interrupted in half section in the middle and on both sides broken a heatable calender roll shown, the hollow cylindrical Roller body 1 on both sides with the flanges of flange pins 2 is connected by means of clamping screws 3. Relative just below the outer shell of the roller body 1, this is from peripheral axially parallel heating holes 4. The feed this heating holes 4 with a heated, for example Medium takes place via one of the flange pins 2, so that this roller can easily be used as a drive roller and also with one moving roller the advantage arises, the inlet and outlet of the rotatable couplings allowing thermal medium only on one the roll neck.
  • the flange pin shown on the left is 2 provided with an axial bores 5, the interior of which by a Inlet pipe 6 is divided.
  • the one surrounding the inlet pipe 6 Area of the bore 5 arranged drain is through a pipe 6 in the enlarged bore of the flange pin 2 supporting cutting disc 8 limited, while the interior of the tube in a behind the Cutting disc 8 leads lying space at the end of the centering pin 31 of the flange pin 2 is closed by a cutting disc 7.

  • Both the groove 11 and the feed bores are expedient here 14, each leading to a specific one of the heating holes 4, executed with a cross section corresponding to the heating holes 4.
  • the ring grooves 10 and 13 are with the front or downstream rooms through inlet holes 12 and return holes 9 connected, the number of those of the connected groups of heating holes, but with a corresponding enlarged cross section are executed. That is true in the roller body itself for two heating holes operated in series 4 a feed hole 14 has been retained by the known, the via the annular groove 10, 13 further holes 9 and 12, however are provided in a smaller number and with a larger cross-section and thus easier to create than in the number of connected Heating holes 4 feed holes to be provided.
  • the groove 11 the number of heating holes to be connected must be provided, in the present case the series operation of in groups of two merged heating holes 4, however, as in the creation of holes 9 and 12, when incorporating the groove 11 advantageous noticeable that this in the softer material of Flange pins are to be inserted.
  • the clamping screws 3 a sufficient field within which they can hold and are able to tighten the flanges.
  • An unwanted one Heating of the roller end areas is by insulating bushes 16 in Limits kept.
  • the power supply is shown on the left Flange pin 2 causes an inlet pipe 6 in its bore 5 is arranged, which is centered by means of the cutting disc 8, while the cutting disc 7 closes the interior to the rear, so that the inside of the roller is not flooded and accordingly on Displacement body can be dispensed with.
  • an insulating tube 17 is also introduced into the bore 5, which is held by means of an equally heat-insulating support disk 18 is, so that the direct heat transfer from the thermal medium is reduced to the flange pin 2.
  • the inlet holes 12 are in one the number of groups of heating holes 4 number falling below with an enlarged cross-section Passage area formed, and here too results Simplified production compared to conventional ones in the roller body 1 provided feed bores 14 having calender rolls Arrangement of the leads in the flange, but not in Roller body usually made from chilled cast iron 1.
  • Figure 5 illustrates by an interrupted settlement in height of the pitch circle of the heating holes 4 their supply.
  • FIG. 6 shows a further development in which two ring grooves 10 and 13 are used, which are opposed by a conical disk 28 be delimited. Again are for each other corresponding parts the reference numbers already known for these used, so that the roller body 1 by means of clamping screws 3 is connected to two flange pins 2 and 40, in which Bore 5 of the flange pin 2 shown on the left is an inlet pipe 6 and an insulating tube supported by means of a support disk 18 17 are introduced.
  • the annular groove 13 is via return holes 9 reduced number and enlarged cross-section connected, while the annular groove 10 is fed via inlet bores 12.
  • a radial groove 29 which is from the annular groove 10 extends to a transverse bridge 30 which extends from the groove 29 proceeding up to the mouth of the following heating holes 4 extends.
  • a guide tube 32 is then rectangular in the groove 29 Cross-section used, the lower opening is on the edge the conical disc 28 sets, and the upper end of a lateral Has opening, which rests on the mouth of the heating bore 4, so that this mouth is connected to the annular groove 10 via the guide tube is.
  • Insulations can be provided here as well, and in the 6, the insulating bushes 16 and the insulating tube 17 are shown, the support plate 18 also from a poor heat conductor exists or is coated or coated with such. Also that directly adjoins the end face of the roller body 1 Guide tube 32 is advantageously made of plastic or another heat-insulating Fabric created. Furthermore, as thermal insulation between the roller body 1 and the flange 2 flat Air chambers 33 formed. A settlement of two groups of holes is shown enlarged in FIG. 7.
