Definitions
- the invention relates to a saw blade with a base body, on which unrestricted teeth with blades are arranged, which are combined in repeating groups to form at least three teeth and are symmetrical to the longitudinal center plane of the base body.
- a saw blade of the type mentioned is known (cf. DE 43 00 622 C2).
- the known saw blade at least two groups of teeth are nested.
- the first of the two groups consists of at least two teeth, which have a decreasing height from tooth to tooth and increasing width.
- the second group of teeth consists of at least two teeth which are of identical design and which represent the teeth with the largest width and the lowest height.
- the well-known saw blade has the Disadvantage that it is relatively sensitive to shock due to the first and highest tooth of the first group of teeth and is also subject to high wear.
- the invention seeks to remedy this.
- the invention has for its object to provide a saw blade that has a lower shock sensitivity and is subject to less wear, at the same time produces a stable degree in the cutting channel and a good surface quality.
- this object is achieved in that the teeth of a group have an increasing height and decreasing width from tooth to tooth.
- a saw blade is created which is shock-resistant and durable.
- the vibration vibrations that normally occur during sawing are reduced.
- the lifespan is increased while the cutting result is improved.
- Figure 1 is a side view of a section of a saw blade with four
- Figure 2 is a top view of the saw blade shown in Figure 1; 3 shows the view from the left of the saw blade shown in Figure 1;
- Figure 4 is a side view of a section of a saw blade with two
- FIG. 5 shows a view corresponding to FIG. 3 of a group of teeth with different phase angles
- FIG. 6a shows a side view of a tooth with a chip divider
- Figure 6b is a top view of the tooth shown in Figure 6a;
- Figure 7a is a side view of a tooth with a roof tooth;
- Figure 7b is a top view of the tooth shown in Figure 7a;
- Figure 8a is a side view of a tooth with chip breaker;
- Figure 8b is a top view of the tooth shown in Figure 8a.
- the saw blade selected as an exemplary embodiment has a base body 1. Unrestricted teeth 2 are arranged on the base body 1. The teeth 2 are combined into groups of at least three teeth.
- Each tooth 2 has a tooth back 21 at its end facing away from the base body 1.
- each tooth 2 On the side facing the cutting direction X (FIGS. 1 and 2), each tooth 2 has a tooth face 22.
- the tooth face 22 is arranged at a rake angle ⁇ to the vertical.
- the rake angle can vary within a group of teeth. It is located in an area that moves counterclockwise from the vertical.
- the tooth back 21 of each tooth 2 is arranged at a clearance angle ⁇ to the horizontal of the saw blade.
- Clearance angle ß is always greater than 0 °.
- the tooth back 21 and the tooth face 22 of each tooth 2 are arranged at a wedge angle ⁇ to one another, which is in any case less than 90 °.
- the teeth 2 have a phase angle ⁇ - FIG. 3 -.
- the phase angle ⁇ can be selected in a range between 5 ° and 60 °.
- the phase angle ⁇ can also vary from tooth to tooth within a group of teeth, as shown in the exemplary embodiment according to FIG. 5, in which the phase angle ⁇ varies between 30 ° and 60 °.
- the teeth 2 combined into a group of teeth have a height h increasing from tooth to tooth.
- the width b of the teeth 2 combined into a group of teeth decreases. It follows that the lowest tooth in a group is the broadest, the highest the narrowest.
- the increase in height from tooth to tooth is at least 1/1000 mm, at most 5/100 mm.
- the decreasing width is available to laterally separate a subsequent tooth in the cutting channel from the pre-cutting tooth.
- the teeth 2 are combined into groups of teeth from at least three teeth.
- the groups of teeth repeat themselves cyclically on the saw band. It is possible for identical groups of teeth to follow one another. There is also the possibility that the successive groups of teeth each have a different number of teeth - Figure 4 -.
- a group G1 consisting of four teeth is followed by a group G2 consisting of three teeth.
- Group G2 follows group G1 again.
- the groups of teeth G1 and G2 are not interleaved. All groups of teeth of the saw band have a height increasing from tooth to tooth and a width decreasing from tooth to tooth.
- the pitch of the saw blade i.e. the distance between the teeth, can be chosen to be constant or variable.
- a chip divider 3 with a small phase is ground in on the tooth back 21 of tooth 2.
- the chip divider 3 divides the chip again or narrows it.
- the width and depth of the chip divider 3 is 0.01 mm to 0.04 mm.
- a roof tooth 4 is attached to tooth face 22.
- the roof tooth 4 is formed by grinding the tooth face 22 at an angle ⁇ .
- the angle ⁇ is preferably in a range between 1 and 15 °.
- the roof tooth 4 on tooth 2 further reduces the impact load on the tooth on the material to be machined. Only the tip of the roof tooth 4 hits the material to be cut, as a result of which the chip rolls over the tip of the tooth.
- a chip breaker 5 is provided in the tooth shown in FIG.
- the chip breaker 5 is formed by a radius at the end of the tooth face 22 facing away from the base body 1 of the saw blade.
- the radius is preferably between 0.1 and 1 mm.
- the chip breaker level 5 is used for materials such as austenites. These materials tend to overheat during machining.
- the chip space fills completely with chips, causing the tooth to break out of the cutting line.
- the chip breaker 5 leads the hot chip into a smaller radius and thus from the surface of the chip space. The chip has no contact with the saw blade during the cooling phase and falls out of the saw blade
- Cutting channel without problems.
- the different geometries described can all be linked together.
- the combination of these geometries means that each tooth within a group does a different job within the cutting channel. Due to the different forces on the individual teeth that occur during sawing, by dividing a chip into several fine chips and by
