Definitions
- the invention relates to a machine knife for trimming books or the like. According to the preamble of claim 1.
- Machine knives of this type have been known for a long time.
- it is known to solder blades or cutting edges made of hardened steel or hard metal to the metal knife carrier and to secure both parts so firmly, i. H. to be inextricably linked. Knives of this type are used above all in so-called 3-knife machines and face cutting machines in the printing industry.
- Such knives can be used several times because they can be reground several times. In doing so, they shorten and have to be readjusted. Regrinding and adjustment are subject to special requirements in terms of quality, accuracy, etc., so that the process parameters relevant to achieving the desired quality and efficiency are subsequently ensured.
- the necessary processing of the knives is usually not carried out by the original manufacturer, but in local service companies which use their own processing methods. This inevitably leads to significant quality losses. In the worst case, process disruptions can occur.
- regrinding is restricted to certain metallic materials with certain metallurgical or chemical compositions.
- the machine knife according to the invention essentially comprises two parts, namely a knife carrier and a blade holder with the blade or cutting edge which can be attached and detached therefrom.
- the latter is inextricably linked to the blade holder.
- the knife holder is no longer subject to wear and is an unchangeable part of the respective machine. If necessary. serves a special recess or the like. The positive reception of the new wear part, namely the blade holder and the blade connected to it.
- the blade is basically made of highly wear-resistant material, such as special metallic materials.
- the invention also permits and favors the use of other materials, in particular ceramics. In the simplest case, the material can be used uncoated, allow great operational reliability and long downtimes, whereby the performance of the machines can be optimally used.
- FIG. 1 is a plan view of a machine knife according to the invention
- FIG. 2 shows the object of FIG. 1 in side view, partly also in section
- FIG. 3 shows the detail A of FIG. 2 in an enlarged view, with a special blade arrangement
- FIG. 5 shows the object of FIG. 4 in a side view, partly also in section
- FIG. 6 shows the detail B of FIG. 5 in an enlarged view, with a different blade arrangement
- FIG. 7 shows the blade before it is connected to the blade holder in an enlarged view
- 8 shows a machine knife according to the invention in an enlarged illustration, similar to the illustrations in FIGS. 3 and 6, and
- FIG 9 shows another machine knife according to the invention in the aforementioned representation.
- a band-shaped or, in plan view, rectangular knife carrier 1 made of metal is provided with a plurality of bores 2 in order to fix it on a machine - not shown here in more detail - d. H. to be able to attach.
- the knife carrier 1 On its free side in the assembled state, the knife carrier 1 has a rabbet-shaped recess 3, into which a strip-shaped blade holder 4 with a trapezoidal cross section is inserted flush and secured with screws - which are not shown here for reasons of clarity - on the knife carrier 1.
- the boundary surfaces of the recess 3 at the inner end as well as the interacting boundary surfaces of the blade holder 4 are at an acute angle to one another, i. H. an angle of less than 90 °. This enables a high form fit in the interest of an even and safe power transmission and a long service life.
- a force seat is formed, so to speak, into which the blade holder 4 is pressed under load and in which it is then held particularly securely.
- the blade holder 4 is made of metal. Its free end, d. H. here its free-standing long side is covered with a blade 7 made of a particularly wear-resistant material. It is a hard metal with a diamond coating, i. H. with a coating
