Definitions
- the invention relates to a method for producing sets according to the preamble of claim 1.
- Sets produced in this way are used for the mechanical processing of suspended fibrous material.
- Sets are e.g. installed in grinding machines - so-called refiners.
- the suspension in refiners has a solids content of about 2 - 8%, in special machines also above.
- In such machines for higher consistency one speaks e.g. of high consistency refiners, dispersers or kneaders.
- Conventional machines have at least one rotor and at least one stator with either disk-shaped or conical surfaces on which the clothing is attached, so that gaps can form between them.
- Many sets have ridges and grooves on the work surfaces, which is why one speaks of "knife sets". It is known that in addition to the shape of such webs, the material from which they are made also has an effect on the processing of the fibrous material.
- the sets are subject to wear and must therefore be replaced at certain intervals. Wear can also cause the machining effect to change during its service life.
- the shape and surface of the sets have an outstanding influence on the machining effect.
- the basic body of a machining tool provides the connection of the machining elements to the other components, for. B. those of a grinder. Because of the high forces that occur in such a grinding machine, particularly high strength requirements are placed on the base body. It must also be possible to fix it securely with the grinder, for which purpose e.g. highly tightened screws are required. Because of these requirements, a particularly strong and tough material is required.
- the clothing heats up. This is due to the high energy density of the machining process and is particularly strong, for example, when grinding with higher material densities.
- the set can be damaged if the connected materials, such as ceramic and chrome steel, have different thermal expansion behavior.
- the particularly well-suited types of ceramic have a significantly lower thermal expansion than chrome steel. This can tear the bond, which leads to a fatal breakage of the clothing.
- ceramics of this type are quite brittle, so that cracks can occur due to thermal expansion in the case of a rigid, flat connection or with several rigid fastening points.
- the invention is based on the object of designing the method for producing sets so that brittle materials which are particularly suitable for the machining elements can be used and that the sets are insensitive to heating.
- Sets produced according to the invention have surface properties which are constant over time and are highly wear-resistant, mechanically robust, thermally insensitive and light in weight.
- Fig. 2 shows a set according to the invention in cut
- the base body 1 shows the base body 1 with a processing element 2 connected to it.
- the strips 5 of the processing element 2 protrude from the projection c and have a large number of end faces 11, which results in a grinding set, which is also referred to as a knife set.
- a non-positive connection e.g. made by gluing.
- the relatively thin adhesive layer formed in this way is very strong and largely rigid, i.e. it is not so elastic that it alone can compensate for the thermal expansion.
- Fig. 2 shows a similar set in side view.
- the base body 1 is fastened to the rotor 8 of the grinding machine by releasable connecting elements 10, which in turn is driven by the shaft 9.
- the sets produced by the method can also be attached to a stator.
- FIG. 3 shows a typical grinding set in supervision.
- segment-shaped processing elements 2 On the circular base body 1 there are segment-shaped processing elements 2. These carry strips 5 with the width b, are straight and partly of different lengths. Curved or more obliquely inclined bars are also conceivable.
- the method according to the invention can also be used if none with Last provided processing elements, but - as shown in Fig. 4 - processing elements 2 ' with end faces 11 ' , which have an abrasively porous surface, are to be used.
- Fig. 5 ' are incorporated recesses 6, the operating element 2 in the complementary projections 7' in the base body 1 so fit that is created on one side of a stop (left example).
- the machining element can be positioned exactly before the connection and the strength of the connection can be increased.
- Other elevations 7 ' can also fill in the recesses 6' and, for example, be cast into the plastic of the base body (example on the right).
