Description
Technical Field
The present invention relates to a swing jaw of a jaw crusher and a jaw crusher for crushing rock material.
Background
A jaw crusher, for example known from DE 19631023 a1, usually has a first crushing jaw and a second crushing jaw, wherein one crushing jaw is usually configured as a fixed crushing jaw and the other crushing jaw is formed as a swinging crushing jaw. They are used to break up hard to very hard materials such as basalt or granite. The material strength results in a correspondingly high load in the jaw crusher, which acts in particular on the swing jaw. To take up the loads, the swing jaws are usually configured as closed box castings, wherein for casting reasons several holes for positioning and holding the casting cores are present in the box. However, these holes have proven to be weak points in the crushing process due to the great forces and stresses acting on them, and these lead to damage to the swing jaw.
Disclosure of Invention
The invention is therefore based on the object of designing a swing jaw in which the stresses occurring in the swing jaw are reduced.
The swing jaw of the jaw crusher comprises a bracket arranged in the top of the swing jaw for pivotably holding the swing jaw on the jaw crusher and a support area in the bottom of the swing jaw for supporting the swing jaw, wherein the swing jaw comprises a hollow body structure for reinforcement purposes, wherein the hollow body structure comprises a plurality of reinforcement elements in a longitudinal cross section of the swing jaw, all reinforcement elements having a common intersection point along their main extension axis.
Due to the single point of intersection in the swing jaw, the force flow between the individual reinforcing elements can be distributed very well. Furthermore, the stresses occurring in the hollow body structure can be reduced. Furthermore, this provides a very torsionally rigid structure, so that the swing jaw no longer needs to be designed as a closed box casting, but can be open on one or both sides. The open structure also has the advantage that no holes for casting cores are required, thus avoiding the weak points in the known swing jaws.
The form of the reinforcing elements that result in a common intersection point is similar to the form of the nodes of the tree branches, so the swing jaw can be described as "biomimetic". In stiffening elements extending to a common intersection point, less mass is required to distribute forces and keep stresses within a lower range than in waffle pattern (waffle pattern). The absence of a front and/or rear panel also allows for a very simple casting of the component. The accessibility of the stiffeners/ribs also allows simple inspection of the quality of the individual stiffeners (inspection of the cavity). Furthermore, due to the resulting accessibility, further functions (such as securing the installation in an open jaw crusher) can be integrated in the carrier structure.
Preferably, the hollow body structure consists, in longitudinal section, of four reinforcing elements arranged in an X-shape with respect to each other. A configuration with exactly four reinforcing elements allows to maintain the force flow of the component while having as low a material usage as possible.
According to a preferred embodiment, the hollow body structure extends from the bracket for pivotably holding the swing jaw up to at least the support area. Furthermore, the reinforcing elements form triangular units in the longitudinal section of the hollow body structure, from which the hollow body structure extends up to the sides.
The swing jaws have a longitudinal center plane extending perpendicular to the pivot axis of the swing jaws, wherein the longitudinal center plane forms a symmetry plane through the common intersection point of the stiffening elements. The common intersection point is therefore arranged centrally and thus allows a good distribution of the forces, moments and stresses occurring.
According to another exemplary embodiment, the swing jaw comprises a front side, a rear side and a first and a second side for fitting the crushing jaw, wherein the hollow body structure is formed to be open on the front side and/or the rear side.
The invention also advantageously relates to a swing jaw having a front side, a rear side and two side portions, wherein the front side is equipped with a crushing jaw. Here, the comminution jaws are arranged on the hollow body structure with a contact area and in this contact area the comminution jaws comprise a reinforcing structure adapted to the hollow body structure, giving an optimum force dissipation.
In order to reinforce the first and second side portions, these side portions may be provided with transverse reinforcements. Furthermore, the swing jaws may be configured such that in a side view the swing jaws taper in a wedge shape from the receptacle for pivotably holding the crushing jaws to the support region, thereby saving mass in the lower region.
Furthermore, it is conceivable to form a front plate on the front side of the swing jaw, which is formed integrally with the hollow body structure. This serves to additionally reinforce the swing jaw. If such a front plate is provided, the rear side is preferably formed open in order to thereby simplify the manufacture of the swing jaw.
The invention also relates to a jaw crusher for crushing rock material, having an inlet for rock material, an outlet for crushed rock material and a first and a second crushing jaw, wherein at least one of the two crushing jaws is configured as a swinging crushing jaw and the at least one swinging crushing jaw is attached to a swinging jaw having the above-mentioned features. The further comminution jaw may optionally be configured to be fixed or oscillating. In the case of a fixed structure, the other of the two crushing jaws is arranged on a fixed carrier structure, wherein the fixed carrier structure further comprises a hollow body structure comprising, in longitudinal section, a plurality of reinforcing elements, all having a common point of intersection along their main extension axis.
Particularly preferably, the hollow body structure of the fixing carrier structure consists in a longitudinal section of four reinforcing elements arranged in an X-shape relative to one another.

Detailed Description
Fig. 1 shows a jaw crusher for crushing rock material, having an inlet 1 for rock material, an outlet 2 for crushed rock material and a first 3 and a second 4 crushing jaw. The first crushing jaw 3 is configured as a swinging crushing jaw and is mounted on a swinging jaw 5 for this purpose. However, the second crushing jaw 4 is arranged on a fixed carrier structure 6. The swing jaw 5 has in the top a bracket 7 for pivotably holding the swing jaw 5 on the jaw crusher. The swing jaw 5 is driven in this region by an eccentric shaft 8. A support region 9 is provided in the lower part of the swing jaw 5, the swing jaw 5 being seated on a press plate 10 in a known manner. The tension anchor 11 ensures a constant contact between the pressure plate 10 and the swing jaw 5. Between the two crushing jaws 3, 4 a crushing gap 12 is formed, in which crushing gap 12 the rock material to be crushed is subjected to compressive stress from the eccentrically driven first crushing jaw 3.
With reference to fig. 2a to 2c, a first exemplary embodiment of the swing jaw 5 is explained in more detail below. In order to reinforce the swing jaw, the swing jaw comprises a hollow body structure 25, the hollow body structure 25 comprising, in a longitudinal section of the swing jaw 5, a plurality of reinforcing elements 26, all reinforcing elements 26 having a single common point of intersection 33 along their main extension axis. The remaining area of the hollow body structure 25 preferably has triangular recesses 15, so that the hollow body structure 25 extends as far as the two sides 16, 17, which sides 16, 17 laterally delimit the hollow body structure 25. The side portions 16, 17 are configured in particular in a U-shape in the cross section of the swing jaw 5. Optionally, the side portions 16, 17 are provided with transverse stiffeners 18, 19. At the top, the hollow body structure 25 is defined by a bracket 7 for holding the swing jaw so that it can pivot about a pivot axis 32. In this exemplary embodiment, the hollow body structure 25 is configured to be open at the bottom. Preferably, the hollow body structure 25 consists, seen in longitudinal section, of four reinforcing elements 26 arranged in an X-shape with respect to one another. Particularly preferably, the X-shaped arrangement of the stiffening element 26 is oriented symmetrically to the longitudinal center plane 20 of the swing jaw 5 extending perpendicularly to the pivot axis 32 and thereby provides an optimal form for dissipating forces and moments occurring during crushing, so that stresses are kept to a minimum.
In the exemplary embodiment shown, the hollow body structure is configured to be open on the front side shown in fig. 2a and on the rear side shown in fig. 2 b. In order to hold the first crushing jaw 3 on the swing jaw 5, on the front side of the swing jaw, a lower clamping strip 22 and an upper clamping device 23 are provided (see fig. 1). Preferably, the rear side of the first crushing jaw has a reinforcing structure (not shown) in its contact area with the swing jaw 5, which reinforcing structure is adapted to the hollow body structure 25 of the swing jaw 5. Fig. 1 also shows a preferred feature according to which the swing jaw 5 tapers in side view from a bracket 7 for pivotably holding the swing jaw to a support region 9 in a wedge-like manner, so that mass is saved in the lower region of the swing jaw.
The second exemplary embodiment shown in fig. 3a to 3c differs from the first exemplary embodiment according to fig. 2a to 2c substantially only in that the hollow body structure 25 is covered on the rear side with a rear wall 30, the rear wall 30 in turn preferably being integrally formed with the hollow body structure 25. On its front side (fig. 3a), however, the hollow body structure is formed open, facilitating production and subsequent inspection of the swing jaw 5 due to better accessibility.
If the jaw crusher is provided with two movable swing jaws (not shown), these swing jaws may be configured according to the above-described exemplary embodiments. Normally, however, one crushing jaw is fixed, while the other crushing jaw is arranged to oscillate. In the exemplary embodiment according to fig. 1, the second comminution jaw 4 is configured to be fixed and held on a fixed carrier structure 6, the fixed carrier structure 6 for example also comprising a hollow body structure which, in a longitudinal section of the fixed comminution jaw, consists of a plurality of reinforcing elements, all of which have a common point of intersection along their main extension axis (not shown in fig. 1).
Preferably, the fixed hollow body structure consists, in longitudinal section, of four reinforcing elements arranged in an X-shape with respect to each other. Similar to the first crushing jaw 3, the second crushing jaw 4 may also be provided with a reinforcing structure which is adapted to the hollow body structure 31 of the carrier structure in the contact area with the carrier structure 6.
It is also conceivable that only the fixed swing jaw has a hollow body structure according to the invention.
Fig. 4 shows a front view of a third exemplary embodiment of the swing jaw 5. The swing jaw 5 has a front plate 28 at its front side, which is formed integrally with the hollow body structure 25 according to the first exemplary embodiment. In addition to this, the swing jaw 5 comprises the above-mentioned features of the first exemplary embodiment.
