Definitions

  • the invention relates to a blow bar for an impact crusher with the features of patent claim 1.
  • Impact crushers are used to crush mineral materials (natural stone or recycling material) and to produce fine or coarse aggregate.
  • the material is brought in free fall into the area of action of the blow bars of a rotor and from there thrown against impact plates. There it breaks.
  • the blow bars are wearing parts and must be replaced regularly.
  • blow bars have two blow areas, ie heads that are used one after the other when one of the heads has reached the wear limit.
  • the blow bars can then be turned around their own longitudinal axis. A head of the rasp bar that is not yet worn out and which was located in a rasp bar holder in the rotor is thereby pushed out so that the rasp bar can also be used with this head until the wear limit is reached.
  • the central area of the blow bars is as small as possible and the head exposed to wear is as large as possible.
  • the central area is too small, high tension can occur in the blow bar.
  • the blow bar can break, which can result in damage to other parts of the impact crusher.
  • the DE 20 2017 103 587 U1 discloses a mirror-symmetrical blow bar according to the type described above. Due to the mirror symmetry, the blow bar can be rotated around its longitudinal axis and also around its vertical axis. The rotational symmetry enables both directions of use in the blow bar holder. The force is introduced exclusively via the inner flanks of a U-shaped mount in the center of the blow bar. For this purpose, there are appropriately designed projections in the form of longitudinal webs on both sides of the blow bar.
  • the U.S. 4,714,207 discloses a comparable design of a blow bar for insertion into an axis-parallel blow bar receptacle.
  • the heads are parallelogram-shifted in the same direction.
  • the rasp bar can be turned and is held in its middle area by a U-shaped holding bar in the rasp bar holder.
  • the prior art is also the DE 295 21 377 U1 which discloses a rasp bar which has two heads and can be turned after one head wears out.
  • the blow bar is held in the blow bar receptacle by laterally projecting strips.
  • the heads are each angularly skewed because all angles between the faces of the head are not equal to 90°.
  • the invention is based on the object of demonstrating a blow bar for an impact crusher which has a long service life and a high degree of utilization.
  • a reversible blow bar is proposed for insertion into an axis-parallel blow bar receptacle of a rotor of an impact crusher.
  • a maximum degree of utilization of the blow bar results when the blow bar can be turned over after one end of the blow bar has been worn.
  • the rasp bar has a middle area in the middle and adjacent to the middle area in each case a beating area, which is also referred to as the head.
  • One of the two heads at the ends of the list is in an operating position, i.e. it protrudes from the rotor. Meanwhile, the other head is protected in a rotor mount of the rotor and can be brought into the operating position by turning the blow bar.
  • the blow bar has a longitudinal axis running in the z-direction, which in the installed position runs parallel to the blow bar receptacle of the rotor.
  • the blow bar has a vertical axis running in the y-direction, which is directed towards a radially outer head surface of the blow bar.
  • the blow bar has a transverse axis running in the x-direction, which is directed towards a longitudinal side of the blow bar. The origin of this coordinate system is at the center of the cross-sectional area of the blow bar.
  • the blow bar is designed to be rotationally symmetrical with respect to its longitudinal axis. It is not mirror-symmetrical in relation to the xz plane and also not in relation to the yz plane, which is perpendicular to it.
  • the blow bar At its upper and lower ends in the vertical direction, the blow bar has a head that is rectangular in cross section. Each head has longitudinal side faces which are parallel to each other at a first distance. This first distance between the front and rear side surfaces defines the thickness of each rectangular head.
  • rectangular means that the side surfaces run parallel to one another within the scope of the manufacturing tolerances and are also parallel to the yz plane.
  • the two heads are not arranged as mirror images, but offset in the transverse direction, ie in the x-direction, by a second distance in opposite directions.
  • the two heads are offset from one another in the transverse direction, which means that there is no mirror symmetry, but rather rotational symmetry with respect to the longitudinal axis.
  • the rasp bar is bent in the transition to the central middle area.
  • the central area runs somewhat diagonally between the two heads. They are located in Transition to the central area on each long side of the blow bar, supporting shoulders, via which centrifugal forces of the blow bar can be introduced into the impact power consumption.
  • a feature of the invention is that the central portion has a thickness over most of its length not less than the thickness of the heads.
  • the "majority" refers to the vast majority, i.e. in particular more than 70% to 90%.
  • a receptacle for a holder can be arranged in the end area of the blow bars. There is a constriction in this area, which also reduces the cross-section in the middle area. However, this constriction is irrelevant for the degree of utilization and for the operational reliability of the blow bar.
  • the thickness of the middle area is not less than the thickness in the area of the heads.
  • the central area is also not smaller than the thickness of the heads over its extrapolated height over the vast majority of its height, in particular completely. Information on the thickness ratios always refers to the unworn condition of the blow bar.
  • said central area is even at least 3% thicker than the heads over most of its length.
  • manufacturing tolerances of +/- 1% are to be expected.
  • the differences in thickness between the central area and the heads are significantly greater in this embodiment of the invention and are preferably in a range of 2-5%, in particular in a range of 3-4%.
  • the blow bar according to the invention has a reinforced cross section and is more secure against breakage in this area.
  • a further advantageous embodiment of the invention provides a contact surface which is formed on each side of the blow bar and is arranged in the transition from the central area to the rear side surface. Forces are transmitted from the blow bar in the radial direction to the rotor via the contact surface, or the torque of the rotor is transmitted to the blow bar via a blow bar holder.
  • the Contact surface is raised. Due to the raised, ie protruding, contact surface, there is an addition of material that allows the surface of the contact surface to be processed without a depression being formed in the blow bar.
  • the contact surface is also raised so that there are no constrictions in this area. This avoids notch stresses.
  • the contact surface is preferably designed only as wide and long as necessary. Therefore, it can also be shorter and narrower than the supporting shoulder.
  • the contact surface itself runs parallel to the yz plane.
  • the raised contact surface is followed by rounded flanks to the rear side surface, the flanks being completely concavely rounded.
  • the advantage of this is that the flanks always remain rounded, regardless of the material removal on the contact surface, so that the notch stresses that occur under load in this area are always kept to a minimum.
  • the highest surface pressures between the rotor and the blow bar occur in the area of the contact surfaces, with the two contact surfaces being exposed to constant wear. It is therefore important that even after changing a blow bar, the new blow bar is as level as possible, i. H. has a flush surface in the area of the contact surfaces. The contact surfaces are therefore machined.
  • the head ends in the support shoulder, which is followed by the central area.
  • the support shoulder therefore protrudes from a rear side surface, but not from the other side surface on the corresponding longitudinal side of the blow bar.
  • the support shoulder also protrudes from the front side surface. This support shoulder increases the contact area between the rasp bar receptacle and the rasp bar. The local surface pressure with regard to the centrifugal forces is reduced.
  • the obtuse angle by which the support shoulder is inclined relative to the side surfaces is also selected to be smaller and in particular smaller than 117°. It is preferably 115°.
  • a smaller angle has the advantage that the blow bar receptacle is exposed to lower spreading forces that are a result of the centrifugal forces acting on the blow bar.
  • the rasp bar acts like a wedge that widens the rasp bar mount. A smaller angle reduces the wedge effect.
  • Another advantage is that the overall length of the central area is reduced as a result. The proportion of material in the central area in relation to the heads is smaller. The degree of utilization is improved.
  • the support shoulder projects in relation to the front side surface, the support shoulder forms flanks of longitudinal ridges which are raised in relation to the front side surface.
  • the longitudinal webs can be trapezoidal in cross section and have flanks on both sides.
  • the flank angles of the longitudinal webs are preferably identical and are preferably in a range from 110° to 117°. In the transition to the sloping surfaces of the mid-central area, the resulting angle is even greater, namely by the angle of the sloping surfaces, which can be 10° to 20°, so that overall a smooth, low-stress transition from the inner flank, i. H. the support shoulder is created towards the middle area.
  • the head in the variant with a longitudinal web already ends at the outer flank of the longitudinal web, not only at the supporting shoulder, in relation to the thickness ratios according to the invention.
  • the thickness specifications of the head refer to the narrowest area of the head without the longitudinal webs.
  • At least one, in particular two, indentations can be formed in the front side surface, in particular in a raised longitudinal web, as a safeguard in the axial direction.
  • An axial lock is, for example, a bolt which, after the insertion of the blow bars, is guided through a blow bar holder and is connected, in particular screwed, to the blow bar holder. Since hardly any forces act in the axial direction, a very simple axial lock is sufficient here.
  • the depressions have a depth that extends to a level that is still above the contact surfaces. They therefore protrude only relatively little into the blow bar and lead to local weakening only to an insignificant extent. However, this effect is less if the indentations are arranged in the raised longitudinal webs.
  • the indentations are preferably arranged directly opposite the contact surfaces, so that there is no reduction in the thickness in this area in relation to the cross section in the x-direction.
  • the design of the blow bars according to the invention is particularly suitable for blow bars with a head thickness of 100 mm and a total height of approximately 300 mm. They are therefore relatively compact and thick blow bars.
  • the diametrically opposite front side surfaces are located at a distance of about 30-40% of the thickness of the head.
  • the decoupled hammer has a total thickness of 130-140% of the thickness of a head.
  • the raised bearing surfaces are approximately 8-15% higher than the thickness of the head, d. H. they protrude by about 10 mm for a head with a thickness of 100 mm. However, they do not increase the overall thickness of the blow bar. However, the overall thickness can increase compared to the above values if additional, raised longitudinal webs are present.
  • the longitudinal webs form the areas that protrude furthest in the x-direction. They can each have a thickness of 10-15% of the thickness of the heads, for example a head with a thickness of 100 mm can have a thickness of 13 mm, so that the blow bar has a total thickness of 148 mm. This roughly corresponds to proportions of 1:1.5 (overall height : overall thickness). Such a compact blow bar is extremely insensitive to breakage in the central area and at the same time has a high degree of utilization.
  • figure 1 shows a rotor 1 of an otherwise not shown impact crusher.
  • the rotor 1 has a horizontal rotor shaft 2 which is mounted in bearings 3,4.
  • the rotor shaft 2 extends horizontally between the bearings 3, 4. It is driven by a pulley 5.
  • On the rotor 1 four blow bars 6 are distributed over the circumference. The blow bars 6 run parallel to the axis of rotation D of the rotor shaft 2.
  • blow bars 6 a Cartesian coordinate system ( Figures 1 to 4 ) referenced.
  • the origin of the coordinate system is in the middle of the blow bar 6, ie at half the length (z-axis), height (y-axis) and width (thickness) (x-axis) of said blow bar 6.
  • the coordinate system refers to the respective blow bar 6 and not on the rotor 1. Since the blow bar 6 is slightly inclined in the installed position, the coordinate system is also in the figures 2 and 3 slightly inclined about the longitudinal axis (z-axis) of the blow bar 6.
  • the x-direction of the coordinate system points in the direction of a surface normal of the front side surface 9.
  • the y-axis is the radial direction and points away from the rotor shaft 2.
  • the z-axis runs parallel to the front side surface 9 and to the axis of rotation D.
  • the figure 2 shows that a total of four blow bars 6 are distributed evenly around the circumference of the rotor 1 .
  • the four blow bars 6 are identical.
  • the blow bar receptacles 7 are depressions running in the longitudinal direction of the rotor 1 , ie parallel to the axis of rotation D of the rotor shaft 2 . In relation to the coordinate system mentioned above, the indentations run in the z-direction.
  • blow bar 6 is not mirror-symmetrical, neither in relation to the horizontal plane, ie the xz plane, nor in relation to the vertical longitudinal plane, ie the yz plane. They are, however, with regard to the central longitudinal axis, which runs in the z-direction, is rotationally symmetrical because it can be mapped onto itself when rotated by 180° around the longitudinal axis.
  • the blow bars 6 each have radially outer head surfaces 8 ( Figures 3 and 4 ). Since the blow bars 6 are cast components, the top surfaces can have a slight slant due to the casting process.
  • the side surfaces 9, 10 of the blow bar 6 run at a parallel distance from one another and are therefore essentially perpendicular to the top surfaces 8 ( figure 3 ).
  • the blow bar 6 has a head 11 of rectangular cross section, each head 11 having said front and rear side surfaces 9, 10 which run parallel to one another at a first distance A1.
  • the distance A1 between the side surfaces 9, 10 is at the same time the thickness D1 of the head 11 in the x-direction ( figure 3 ).
  • Each head 11 has a constant thickness D1 over its entire length and height, so that the cross section of the head 11 is rectangular.
  • the front side surface 9 serves as a striking surface, which is exposed to constant wear during operation.
  • the blow bar 6 has a central area 12 between the two heads 11, in which the longitudinal axis (z-axis) runs centrally.
  • the side surfaces 9, 10 are parallel to the y-z plane, the heads 11 being offset transversely (x-direction) by a second distance A2 in the opposite direction to the y-z plane.
  • the second distance A2 is 10 to 20%, in particular 15 - 20% of the thickness D1 of the head 11.
  • a feature of the invention is that the center portion 12 has a thickness D2 over most of its length which is at least not less than the thickness D1 of the heads 11. While the thickness D1 of the head 11 is measured in the x-direction, the thickness D2 of the center portion 12 to a measurement direction perpendicular to the slanted center portion 12. The thickness D2 of the center portion is also not smaller than the thickness D1 if the measuring direction deviates.
  • the cross-section in the mid-central area 12 is not weakened and has no constrictions which reduce its own thickness D2 with respect to the thickness D1 of the heads 11.
  • the thickness D2 at the central portion is the same as the thickness D1 of the head. The security against breakage in this central central area 12 is significantly increased.
  • the blow bar 6 has a supporting shoulder 13 which protrudes in the x-direction in relation to the front side surface 9. The greater the lateral offset of the heads 11, the further the supporting shoulder 13 protrudes .
  • FIG. 3 shows how the support shoulder 13 serves to hold the blow bar 6 in the blow bar receptacle 7 in the installed position.
  • the support shoulder 13 is supported on a rear blow bar holder 15 which is welded into the rotor 1.
  • figure 3 shows wear lines of the upper head 11 with a dashed line. The wear begins at the corner between the front side surface 9 in the transition to the head surface 8. If the wear has progressed too far, the blow bar 6 is turned over.
  • the sectional view of figure 3 also shows that rectangular areas are arranged within the heads 11, which are made of a more wear-resistant material than the surrounding jacket of the blow bar 6. It can be a matter of embedding a ceramic material.
  • the material-removing post-processing inevitably leads to a reduction in the cross section of the blow bar, which is undesirable according to the invention if constrictions are formed as a result.
  • the contact surface 16 is therefore raised to such an extent in relation to the rear side surface 10 of the head 11 that there is always enough material available for the material-removing machining without a constriction being formed.
  • the contact surface protrudes by the amount A3, which corresponds to 10% of the thickness D1 of the head 11.
  • the diametrically opposite second contact surface 16 is used for support on a front blow bar holder 17.
  • a high torque about the longitudinal axis is exerted on the blow bar 6 by impacting material.
  • the abutment surfaces on the blow bar holders 15, 17 belonging to the contact surfaces 16 run parallel to the side surfaces 9, 10 of the blow bar 6 within the scope of the manufacturing tolerances, so that only normal forces are transmitted via the contact surfaces 16. Centrifugal forces are transmitted via the separate support shoulder. This functional separation is favorable for the power transmission and avoids stress peaks due to the superimposition of normal forces and bending moments within the blow bar 6.
  • the blow bar holders 15, 17 guide and hold the blow bar 6 in the longitudinal and circumferential direction. Securing against axial displacement in the longitudinal direction of the rotor 1 takes place via at least one depression 18 adjacent to the support shoulder 13 ( figure 3 ).
  • the indentations 18 are designed to accommodate a detachably insertable axial lock 19 ( Figures 5 to 7 ).
  • This axial lock 19 can be a locking pin, for example, which passes through a hole in the blow bar holder 15 and engages in the recess 18 .
  • the at least one axial lock 19 can be screwed to the blow bar holder 15 to fix the position.
  • the axial lock 19 has a bolt 20 welded to a plate 26 with a bore 27 for a screw, such as Figures 8 and 9 show.
  • the thickness of the blow bar 6 measured in the x-direction is greatest in this area. According to the invention, it is also not smaller than the thickness D1 of the heads 11 in this area, also minus the depth of the depressions 18.
  • the support shoulder 13 is intended to absorb the centrifugal forces that act on the blow bar 6 as a result of the rotary movement.
  • the support shoulder 13 can therefore be directly adjacent to a front side face 9 .
  • the support shoulder 13 can additionally protrude in relation to the front side surface 9 .
  • 9 longitudinal webs 14 are arranged on the front side surfaces.
  • the Figures 5 and 6 show the differences between a blow bar 6 with and without the longitudinal webs 14.
  • the blow bar 6 of figure 6 is also in figure 7 shown where for figure 7 the same reference numerals are used as for figure 5 .
  • the only difference is the raised longitudinal bar 14 on the support shoulder 13. Incidentally, for figure 7 to the explanations figure 4 referenced.
  • FIGS. 5 and 6 also show that at the ends of the blow bar 6 openings 21 are arranged in end depressions 25 adjacent to the contact surface 16 .
  • the openings 21 and recesses 25 are used for recording an assembly tool to insert the very heavy blow bars 6 into the blow bar receptacle 7 or to remove them.
  • the central area 12 of the blow bars 6 is that area which does not wear out through contact with the material to be shredded.
  • the central area 12 includes the functional surfaces over which the blow bar 6 is held.
  • the middle area 12 ends at the level of the outer flanks 24 of the contact surfaces 16.
  • the middle area 12 ends with the end of the depressions 18 or, if present, with the outer flanks of the longitudinal webs 14 ( figure 4 , figure 7 ).
  • the central area 12 has inclined surfaces 22 on both sides, which run parallel to one another. They run at an angle W2 deviating from 90° to the yz plane.
  • the angle W2 is determined by the offset of the two heads 11 in the transverse direction and the distance between the heads 11 in the vertical direction. It is less than 180°. In this embodiment it is 165° ( figure 4 ).
  • a flank angle W1 of the support shoulder 13 is 115° in relation to the rear side face 10.
  • the flank angle W3 is also 115° in this example.
  • the inclined surfaces 22 therefore enclose an angle of 130° with the support shoulder 13 .
  • the steep angle W1 of the support shoulders 13 means that the support shoulders 13 are only arranged at a small parallel distance A4 from one another.
  • the support shoulders are located near the center of the blow bar 6. The forces are therefore introduced relatively centrally into the reinforced central area 12 .
  • the voltage paths are short. The material stress is lower.
  • transition 23 there is a rounded transition 23 between the inclined surface 22 and the supporting shoulder 13.
  • the rounding of the transition 23 avoids stress peaks.
  • the rounding is smaller than that of the flanks 24 of the contact surface 16.
  • the transition 23 lies in particular at the height of the x-axis.
  • the contact surfaces 16 are trapezoidal in cross section. Their flanks 24 are rounded with particularly large radii so that there are as few stress peaks as possible in the transition to the heads 11.
  • the concave rounded edges 24 also have the advantage that, regardless of how much material has to be removed from the contact surfaces, a rounded transition to the side surfaces 10 and the inclined surfaces 22 always remains.
  • figure 7 shows that the longitudinal web 14 is trapezoidal overall, with the flanks 24 of the longitudinal web 14 having the same flank angle as the supporting shoulder 13 which adjoins the longitudinal web 14 .
  • the figure 7 the total thickness D4 of the blow bar 6.
