Definitions
- the invention relates to hard body for partial insertion into recesses on the surface of the rolls of roller presses for the crushing granular material, wherein in the operation of the roller press the spaces between the rolling surface outwardly protruding hard bodies are filled with compressed fine-grained material for autogenous wear protection.
- the pin-shaped stud bolts sit firmly in their blind holes. If it is necessary to replace individual stud bolts, it may be difficult to disassemble the stud bolts, especially if they are partly broken in their blind bores.
- the invention has for its object to provide for the above-mentioned grid armor rolls roller presses hard body, which are relatively inexpensive to manufacture and especially relatively easy even in the damaged state from their respective roll body recesses for the purpose of roll repair are again disassembled ,
- the hard body according to the invention namely the prefabricated usually produced by powder metallurgy z.
- pin-shaped or cylindrical cylindrical carbide studs have a central recess extending from the radially inner end of the hard body over at least a portion of the hard body height. This central recess is dimensioned so that it does not weaken the hard body, but in any case by saving material for cost reduction in the production of prefabricated hard body contributes.
- the more important advantage of the central recess in the prefabricated hard body is that the central recess is utilized for disassembling the hard body fixed in the respective roller body recess by passing through a central connection opening or opening into the central recess of the hard body, even if this should be partially broken Connection hole a suitable tool and / or a pressure medium such as pressure oil, compressed air, etc. for pulling out or pushing out and thus be introduced for disassembly of the hard body. In this way, damaged parts of equipped with the grid armor roll surfaces of roller presses can be repaired with relatively little effort.
- the prefabricated, in particular powder-metallurgically produced cemented carbide bodies can also be designed such that the central recess extending from the radially inner end of the hard body over a part of the hard body height has a larger diameter than the adjoining to the radially outer end of the Hard body leading central recess, wherein at the transition from the radially inner recess of larger diameter to the radially outer recess of smaller diameter, a step is formed, which is suitable for attacking a suitable tool for disassembly of the hard body by pulling out of its respective Walzenausströmström.
- FIG. 1 shows a vertical section of a cylindrical hard body with a central recess inserted in a bore of a waist jacket in a first embodiment
- FIG. 3 shows a corresponding hard body in a third embodiment.
- Fig. 1 shows a prefabricated cylindrical, in particular made of sintered hard metal powder metallurgy hard body 10, which is inserted into a corresponding bore of the roll shell 1 1, z. B. is glued, and having such a length or height that it protrudes from the surface of the roll shell 1 1 to the outside, so that by a plurality of such on the surface of the roll shell 1 1 of the rollers of a roller press arranged hard body, the above-mentioned grid armor comes with the autogenous wear protection stands.
- the prefabricated hard body 10 has a prefabricated central recess 12, which extends from the radially inner end of the hard body over the entire height or length of the hard body, that is, the central recess 12 is a through hole. If there is a partial or complete damage of the hard body 10 during operation of the roller press for crushing granular material, then the through-opening 12 serves to facilitate disassembly of the hard body after it has been cleaned from the good material, by inserting a suitable tool into the through-opening 12 and / or a pressure medium such as pressure oil, compressed air, etc. for pulling / pushing out of the hard body 10 are introduced.
- a suitable tool into the through-opening 12 and / or a pressure medium such as pressure oil, compressed air, etc. for pulling / pushing out of the hard body 10 are introduced.
- the central passage opening of the hard body 10a is formed so that the extending from the radially inner end of the hard body 10a over a portion of the hard body height extending central recess 13 has a larger diameter than the adjoining the radially outer end of the Hard body leading central recess 14, wherein at the transition from the radially inner recess of larger diameter to the radially outer recess smaller diameter a step 15 for the attack of a tool for disassembly of the hard body 10a is formed from its respective roller bore.
- the disassembled recesses 14 and 13 are cleaned by the grinding stock treated in the roller press before disassembly of the hard body 10a.
- the originally existing central recess 13, which originates from the radially inner end of the hard body 10b, is not continuous at the top, but initially closed at the top.
- the disassembly of the hard body 10b introduced into this from the outside inwards with a suitable tool indicated by dashed lines auxiliary bore then then the disassembly of this type of hard body 10b can be done.
- the hard bodies may have their radially inner ends and, correspondingly, the roll body recesses approximately the curved shape of a hemispherical calotte 16 in their deepest region in all embodiments.
