Definitions
- the invention relates to a circular saw blade, consisting of a support body and a plurality of inserted in the support body distributed over the circumference, a front rake face and a rear contact surface and a cutting edge forming a cutting circle diameter F having cutting plates, with a chip space formed in front of each cutting plate and a plurality of Expansion slots arranged around the circumference and extending radially inwards, which are essentially triangular
- Such a circular saw blade is known for example from DE 92 16 744 U.
- the expansion slots are used to absorb thermal expansion and
- the triangular final configuration has the task of converting the vibrational energy into heat through friction.
- Circular sawing machines are known in which the saw blades are firmly clamped between the flanges on the shaft, and those in which the saw blades are loosely placed on a spline or polygon shaft and are guided on the supporting body between fixed and flowing guides (master blade guides).
- the saw blades are both clamped between flanges and additionally guided on the support body.
- the invention has for its object to develop the circular saw blade described above so that it has a stable vibration behavior has when it is used in circular sawing machines in which it is both clamped between flanges and guided in the outer region of the support body.
- a generic saw blade is characterized by the following features:
- the flight circle diameter is a maximum of 2 mm larger than the diameter of the supporting body
- the smallest chip space diameter of each chip space is a maximum of 13 mm smaller than the flight circle diameter
- This configuration forms a geometrical shape which provides the required internal stresses in the supporting body for the multiple clamping of the tool.
- the natural frequency of the saw blade achieved by these measures leads to quieter running behavior.
- the gear rim is very closed due to the small chip space diameter and the small difference between the flight circle diameter and the support body diameter creates a circular chip thickness limiter in a shape that results in a maximum chip thickness of less than 1 mm.
- This chip thickness limitation ensures that the saw is extremely stable during operation, especially with knotty and cracked woods.
- the conical arrangement of the rake face and the contact face results in a positive change in the minor cutting edge geometry. In addition to the quieter operating behavior, especially of fast-running circular saw blades, the cutting quality is also increased.
- the angle of inclination between the rake face and the contact face of the cutting plates is preferably in the range from 1 ° to 7 °.
- the width of the expansion slots is preferably 0.3 mm.
- the expansion slots can be filled with a permanently elastic material in order to avoid impairing the guiding properties in the outer region of the support body.
- the support body can be provided with a surface coating. This ensures the cleanliness of the management level as well as increased cutting quality and tool life.
- Figure 1 the view of a circular saw blade
- the circular saw blade consists of the supporting body 1 and the cutting plates 2 which are soldered or glued into the supporting body 1 and which form the saw teeth.
- a chip space 3 is introduced in front of each insert 2.
- In the middle of the supporting body 1 there is a bore 7 for plugging onto the shaft of a circular saw machine, which is not shown here.
- an expansion slot 4 arises at the deepest point (smallest chip space diameter), which is initially guided radially inwards in a straight region 6 and at the end merges into a triangular end configuration 5.
- the geometric center of the triangular region 5 forms the center Z.
- the distance L of the expansion slot 4 from its origin to the center is a maximum of 17 mm.
- the flight circle diameter F of the cutting edge formed on the cutting plate 2 is, as shown in FIG. 3, a maximum of 2 mm larger than the diameter T of the supporting body 1. This results in a maximum chip thickness of maximum 1 mm on the workpiece
- the smallest chip space diameter S of each chip space 3 is a maximum of 1 3 mm smaller than the flight circle diameter F.
- the rake face 2a of the insert 2 extends at an angle of 1 ° to 7 ° with respect to the contact surface 2b with which the insert 2 rests in the support body ⁇ .
- the circular saw blade is provided with a surface coating.
- the expansion slot 4 is designed to be wider than in the region 5 which runs in a triangular shape.
- the expansion slot 4 can be filled with a permanently elastic mass, which can provide improved guidance.
- the guiding device formed in the sawing machine is usually operated by compressed air. An air cushion is therefore built up for guiding the supporting body 1. Closed expansion slots reduce the air required for guidance.
