Instead of costly retaining rings of conventional knife systems, the KNECHT K 24 cutter knife system uses a combination of a toothed profile sleeve and simple intermediate rings. The top priority of the K 24 cutter knife system is simple handling and maximum operational safety. Therefore, no moving parts such as bolts or screws are used.
K 24 Cutter Knife System
The complete cutting system, consisting of knives, clamping and balancing elements comes from one source. The individual components of the system are manufactured using state-of-the-art production processes and are perfectly matched to each other. The result is a very smooth running of the cutting system – an important prerequisite for high breakage resistance.
Process-related, each cutter knife cutting system operates in a temperature range between approx. -4°C to +70°C. To prevent bending of clamping elements due to the resulting linear expansions, these must be compensated.
The HSM 100 hydromechanical clamping nut compensates linear expansions. Regardless of the operating condition, the knives are always clamped with the same force and the clamping elements are protected against overstressing.
In food production, the highest and above all constant quality standards are required. The K 24 cutter knife system can be used on all cutter types and brands. This makes it easier to meet the required standards with a unified cutting system.
The advantages at a glance
Profile sleeve
The profile sleeve allows the blades to be installed in 24 different positions (15° offset). This allows many knife groupings. Depending on operational requirements, the K 24 cutter knife system can always be operated with the optimum knife grouping. The toothing prevents the knives from tilting or unintentional loosening during installation. This minimizes the risk of injury when handling the cutting system.
Balancing
The K 24 cutter knives are dynamically balanced on the knife shaft. Precisely calculated balancing elements ensure the maximum running smoothness of the cutting system for every knife combination. Re-balancing, for example after grinding, is not necessary. The installation time for an 8-knife set is less than 5 minutes (500-750 l bowl cutter).
Hydromechanical clamping nut HSM 100
The clamping nut compensates for linear expansions of the cutting system caused by temperature changes, e.g. in cooking cutters. Bending of clamping elements due to excessive clamping force is therefore impossible. This significantly increases the breakage resistance of the cutting system.
Hydraulic pump
The HSM 100 does not require any clamping wrench. With a small hydraulic hand pump the cutter knives are clamped quickly, easily and reliably with approx. 90 kN (9 tons). The pump is equipped with an overload protection. This protects the cutting system from overstressing due to excessive clamping force.
Significantly increased breakage resistance
The forces acting on the cutting system during the cutting process lead to a particularly high load on the cutter knives at the clamping points, as well as to stress on the spacer rings. In the K 24 cutter knife system, the spacer rings can be made completely out of soft materials such as plastic or light metal. They effectively dampen the vibrations of the cutter knives. Abrupt loads are reduced, and breakage resistance is significantly increased. In addition, there is no longer steel on steel at the clamping points of the knives. Contact corrosion is thus minimized.
