Definitions
- the subject of the present invention is a bath saw blade with a plurality of teeth.
- Band and circular saws for metalworking are known from the prior art.
- Band and circular saws consist of a saw body from which teeth are machined by means of machining. It is also known from the prior art to produce tooth tips made of hardened material, such as carbide or HSS.
- a lubricant and coolant fluid for example an emulsion of water and oils, which serves to carry away the thermal accumulation and chips created in the cutting channel by friction.
- Object of the present invention is therefore to provide a saw blade geometry, especially in band saw blades, with which it is possible to ensure the cutting performance and quality of cut while reducing lubricant and coolant.
- the band saw blade according to the invention has a multiplicity of teeth, which are spaced apart from one another by chip spaces, wherein at least some chip spaces have knob-like bulges. According to the invention, it is not necessary for such nub-like bulges to be provided in each chip space. It is also advantageous to arrange the bulges according to the invention in every second chip space. It is also possible to arrange the bulges according to the invention in every third or fourth chip space.
- a knob-like bulge is arranged at least in a chip space of the saw blade.
- nub-like bulges can be arranged substantially uniformly or evenly in the chip spaces and are expediently located near the lowest point of the chip spaces.
- the knob-like bulges are suitably shaped and arranged in the chip space that the introduced
- Lubricant and coolant liquid as long as possible, i. while the chip space is in
- Cutting channel is located in this remains and thus a longer residence time of the lubricant and coolant liquid is reached on the saw blade.
- the contour change according to the invention in the chip space prevents the lubricant and coolant liquid from rapidly flowing past the saw blade and the desired temperature removal does not proceed optimally. Likewise, it is achieved by the contour change according to the invention in the chip space that the lubricating and coolant fluid can better develop the lubricating function, since the lubricant and coolant liquid at the knob-like bulges and in their interstices longer forms a lubricating film in the cutting channel.
- the residence time of the coolant in the chip space is substantially increased with the saw blade according to the invention, in order to also achieve a better and more efficient heat dissipation performance.
- the contour of the knob-like bulges is to be chosen so that the flow of forces and the chip removal in the saw blade during sawing is not hindered and any tooth breakage is prevented.
- the knob-like bulges have no cutting function.
- the knob-like bulges can be comb-shaped or have a polygonal contour. It is also possible that the knob-like bulges have a spherical contour and / or different height.
- the number of knob-like bulges as well as their arrangement and contour can be made dependent on the tooth pitch and the tooth height.
- knob-like bulges are formed like a sawtooth with a steep and a gently sloping edge.
- the cutting material is made of hard metal, HSS or another hard material.
- the teeth of the saw blade are coated with a layer of hard material.
- Fig. 1 is a side view of a saw blade according to the invention
- Fig. 2 is a detail view of a saw blade according to the invention with lubricating and
- Coolant liquid; 3 shows a detailed view of a saw blade according to the invention according to FIG. 2.
- Figure 1 shows a portion of a side view of a saw blade according to the invention with teeth 1 a to 1 d. Between the teeth 1 a to 1 d is in each case the chip space 4a to 4d. In an uncritical for the forces and moments of the saw blade area nub-like bulges 2 are arranged in the chip space 4a to 4d. According to FIG. 1, the chip space 4a is arranged on a lower level H with respect to the chip spaces 4b to 4d. Likewise, the width of the chip spaces 4a to 4d is formed differently. According to the invention, it is possible to make the knob-like bulges 2 in the chip spaces 4a to 4d different, ie the contour, the length, the height, and the number on technical to adapt to changing requirements. Thus, it may be useful, for example, to vary the contour, the length, the height and / or the number of knob-like protrusions 2 from chip space to chip space in order to avoid resonances.
- FIG. 2 shows a detailed view of a saw blade according to the invention, wherein the lubricant and coolant liquid 3 adheres as a film on the knob-like bulges 2.
- the knob-like bulges 2 are designed and matched to the surface tension of the lubricant and coolant liquid such that a meniscus of lubricating and coolant fluid can form between the individual knob-like bulges 2.
- the flank shape of the knob-like bulges 2 and the height and surface quality can be of importance.
- the knob-like bulges are milled into the saw body.
- the knob-like bulges extend over the entire width of the saw blade and thus form transversal rectilinear channels (not shown) for the saw blade, in which drops of coolant liquid 3 collect on account of their surface tension.
- FIG. 3 shows a section of a preferred embodiment of the present invention with dimensions for the knob-like bulges 2 according to the invention.
- the knob-like bulges have, for example, a height of 0.5 mm and a distance between two adjacent vertices of 1.6 mm.
- the pitch angle relative to the horizontal is in sawing direction at about 45 ° and forms a steep edge and on the rear side at 30 ° and forms a gently sloping edge.
- it is advantageous to choose the radius of curvature for example, in the order of 0.4 mm.
- For the dimensioning of the radius of curvature of the vertex angle (not shown), it is recommended to choose a value between 0.2 mm and 0.8 mm.
