Knife holder for industrial materials

The utility model is in the field of industrial scissors. These are used extensively in workshops to cut metal wires, rods, bores, nets, and sieves, as well such scissors are indispensable on modern 3 & ,. th, to cut wire reinforcement and reinforcement mesh, but also pipes, rods and the like. For many too other purposes are useful to such industries

In the nature of their use is that they have to be operated even by inexperienced workers, which the workpieces do not distribute it evenly over the length of the cutting blade, so that the blades are worn unevenly.

70142813017.70

Above all, such industrial scissors are required to work quickly and evenly. This calls for a knife, which are always sufficiently sharp over their entire length. As a result However, the knives use themselves proportionately to the high demands quickly and unevenly. This is where the new utility model comes into play.

Ss solves the task of creating knife holders for industrial scissors, which ensure that the knives are always sharp within the cutting area of the scissors

The utility model is based on the knowledge that the knife - Holders for industrial scissors are non-positively and form-fittingly designed as clamping jaws with the highest operational reliability let that you can attach machine saw blades to the largest extent in such clamping jaws. Such machine saw blades can easily be set up as knives according to the new pattern · These knives are both lengthways and adjustable usable with regard to its two long edges; they can be used for both the upper and lower knife.

The new knife holder means that both the readiness for use as well as the performance of industrial scissors is significantly increased. In addition, the old brewing process of reworked machine saw blades saved valuable material and the production of such scissors as well as yours

Utilization area increased.

To solve the problem , a clamping jaw serves as a knife holder for industrial scissors, which clamps a machine saw blade as a knife by means of clamping screws, leaving a cutting edge outside the edge of the holder facing the workpiece.

Its improvement is that the saw blade is ground to cut along both edges

It is advantageous that the saw blades for changing the cutting edges are optionally longitudinally displaceable with respect to the holder.

It is also useful that the holder is clamped within grooves.

It has also been proven that the jaw for the saw blade as an upper knife and a terminal strip for the saw blade as Ontermesser is a terminal strip.

It is also advantageous that the holder has one or more conventional ones Contains or interacts with shear bushes.

The new pattern is graphically more natural in some exemplary but preferred configurations in the drawing Size shown!

Pigur 1 shows a Hesser holder with an upper mesa for «a domestic

industry with some broken away parts;

Pigur 2 is an operational Hesserhalter according to Figure 1 in an operational state;

Pigur 3 is the diagram of the main parts of an industry above · with knife holders for the upper and lower knife in a modified design.

Han recognizes in Pigur 1 a Hesserhalter 1 for an upper knife The earlier machine saw blade 3 for the upper knife is clamped into the Balter 1 by means of the fastening means 2 in such a way that that the lower edge 4 of the Hessers with cutting edge 4a de "saw blade in a selectable distance below the against the tool" directed edge 5 of the knife holder 1 for the upper knife protrudes The right clamping jaw 6 is gripped by the fastening screw 2

In addition, the industrial is designed as usual, by attaching the holder to the screen

In Pigur 2 you can see the grooved clamping jaws 6 and 6a _t ti · in Pigur 1 are on the rear side. Is it clear that the machine saw blade 3 can be pushed back and forth across the length of the jaw by simple LSsva and

Then tighten the nail screw or similar fastener 2.

In Figure 3 it is shown how the holder 1 for the upper fair, and the holder 1a for the lower cutter with respect to the cutting edges of the saw blades 3 in the upper cutter and 3a in the lower cutter cooperate in that the edges 4 and 4a exert their cutting action. For this purpose they stand accordingly directed towards the workpiece opposite the edges 5 of the knife holder before.

In the case of the embodiment according to FIG. 3, the clamping in the knife holder exercised by the clamping strips 7 for the upper knife and 7a for the lower knifeFastening means are used for clamping, which attack through the hole 8 in the holder. The knives in the embodiment according to FIG. 3 are also both longitudinally displaceable than they can also be rotated 180 °. The cutting edge that is not used is accident-proof within the Jaw mounted. It can be seen that the knife holder 1 with its jaws orter clamping strips are of any length and therefore those of the respective industrial scissors desired services can be adjusted.
