- Nilles s7 ABSTRACT I In a large size jaw crusher for stones and the like a stationary housing wall and a pitman are each provided with a pair of endwise aligned die plates. Sets of mounting bolts secure the die plates, respectively, to the housing wall and pitman, and each pair of die plates is provided with an interlocking finger joint across its width. The interlocking finger joint couples the endwise aligned die plates together so that lateral thrust components of the crushing; force will'be trans mitted from either die plate to its companion die plate, and the mounting bolts for both die plateswill complement each other in taking up such lateral thrust components.
- Jaw crushers for stones and the like are conventionally equipped with stationary and swingable replaceable die plates, and retaining wedges are usually employed to secure the stationary die plates to a wall of thecrusherhousing and the swingable die plates to a pitman or like swingable backing structure.
- Such conventional die mounting is not well suited for large size crushers wherein the stationary and movable jaws are of'considerable length such as9 or 10 feet, and of considerable width such as 4 or feet.
- the preferred material for the die plates is manganese steel, and constructing the die plates in the form of large single piece manganese steel castings would have several disadvantages. For example, such castings due to their great weight, would be difficult to handle for installation and replacement. Further, a good deal of material would be longitudinal expansion'would cause it to buckle and proper contact with the backing structure would be lost.
- a well known characteristic of manganese steel is that it is practically unmachineable with ordinary cutting tools. Accordingly, the die sections would have to be cast with cored out holes for the mounting bolts, and in order to accommodate unavoidable variations of the castings ample lateral clearance would have to be provided for the mounting bolts within the cored out holes. In operation of the crusher, lateral thrust components ofthe crushing force normally arise and act upon the die sections so that the latter tend to shift sidewise rela- .tive to the backing structure. Due to therelatively large lateral clearance of the mounting bolts in the die openings shifting of the die.
- a further object of the invention is to provide an improved jaw crusher die which lends itself to lateral in- 2 terlocking engagement with an adjacent companion die.
- a still further object of the invention is to provide an improved jaw crusher die of the above mentioned character which not only lends itself to lateral interlocking engagement with an adjacent companion die but which is also endwise interlockable with a common backing structure for both dies.
- FIG. 1 is a perspective view of a rock crusher with parts broken away to show die plate mountings embodying the invention
- FIG. 2 is an elevational view of the crusher shown in FIG. 1 with parts broken away and shown in section;
- FIG. 3 is a view in the direction of arrows 3-3 in FIG. 2 showing upper and lower swinging die plates and an interlocking finger joint therebetween;
- FIG. 4 is a view in the direction of arrows 4-4 in FIG.
- FIG. 5 is an exploded perspective view of the swinging jaw in the crusher shown in FIG. 1;
- FIG. 6 is an exploded perspective view of the stationary jaw in the crusher shown in FIG. 1;
- FIG. 7' is an explanatory sketch of load conditions arising in operationof the crusher shown in FIG. 1.
- the swinging jaw assembly incorporates a cast steel pitman 7 which is conventionally mounted on the upper housing section by means of an eccentric shaft 5.
- a driving sheave 8 and a flywheel 9 are mounted on opposite ends of the shaft 5, and a. toggle plate 11 and a spring loaded retainer rod 12 are operatively interposed between the free end of the pitman and the lower housing section in conventional manner.
- the pitman 7 is provided with an upper cast manganese steel die plate 13 and with a lower east manganese steel die plate '14. Referring to FIGS. 3 and 5, theupper die plate 13 is provided with a plurality of cored mounting holes 16, and the lower die plate 14 is similarly pro vided with a plurality of cored mounting holes 17.
- the pitman 7 has cored bolt holes 18 at substantially the same center spacings as the mounting holes 16 of the upper die plate 13, and the pitman further has cored bolt holes 19 at substantially the same center spacings as the mounting holes 17 of the lower die plate 14.
- the upper die plate 13 is drawn up against machined seating strips 21 of the pitman 7 by a set of bolts 22 which extend through registering pairs of holes 16 and 18, and carry nuts and jam nuts 24 on their threaded ends.
- the lower die plate 14 is similarly drawn up against the seating strips 21 of the pitman 7 by another set of bolts 23 which extend through registering pairs of holes 17 and 19 and have nuts and jaminuts 26 on their threaded ends.
- the shanks of the bolts 22, 23 have relatively ample lateral clearance in the holes 18 and 19, respectively, of the cast pitman, and in the holes 16 and 17, respectively, of the cast die plates 13 and 14. Ample lateral clearance of the bolts 22, 23 in the die plate holes and in the pitman holes is necessitated by the fact that'all of these holes are cored and therefore cannot be held closely to exactly the same center distances.
- the upper and lower die plates 13 and 14 are corrugated in conventional manner, transversely spaced ribs 27 extending lengthwise between the opposite ends of the die plate 13, and transversely spaced ribs 28 extending lengthwise. between the opposite ends of the die plate 14.
- the upper die plate 13 is provided with a row of alternating projections 29 and recesses 31 along its lower edge, these projections and recesses extending lengthwise of the plate 13 and transversely of the holes 16 as viewed in FIG. 3.
- a corresponding row of alternating recesses 32 and projections 33 is provided along the upper edge of the lower die plate 14, and in the assembled condition of the swinging jaw assembly as best shown in FIG.
- the projections 29 of the upper die plate interlock with the recesses 32 of the lower die plate; and the projections 33 of the lower die plate interlock with the recesses 31 of the upper die plate.
- the confronting projections and recesses of the upper and lower die plates provide an interlocking finger joint across their width, and such joint serves two principal purposes. First, it keeps the ribs 27 and 28 of the upper and lower die plates in longitudinal alignment with each other; and in the second place, the interlocking finger joint enables the mounting bolts 22, 23 to complement each other in taking up lateral thrust components of the crushing force as will be explained hereinbelow with reference to FIG. 7.
- the stationary jaw assembly like the swinging jaw assembly, is provided with an upper cast manganese steel die plate 34 and with a lower east manganese steel die plate 36.
- the upper die plate 34 faces an upright wall portion 38 of the upper housing section 2 and is drawn up against machined seating strips 37 by means of a set of bolts 39 which extend through cored holes 41 of the upper die plate 34 and registering bored holes 42 of the upper housing wall, the bolts 39 having nuts and jam nuts 43 on their threaded ends.
- the stationary lower die plate 36 faces an upright wall portion 46 which is coplanar with the upper wall portion 38, and the lower die plate 36 is drawn up against machined seating strips 44 on the wall portion 46 of the lower housing section -2, by means of aset of bolts 47 which extend through cored holes 48 of the lower die plate 36 and registering bored holes 49 of the lower housing wall, the bolts 47carrying nuts and jam nuts 51 on their threaded ends.
- the upper and lower die plates of the stationary jaw assembly have corrugated crushing faces and are coupled together by an interlocking finger joint, the upperv die plate 34 having a row of alternating, lengthwise extending projections 52 and recesses 53 along its lower edge, and the lower die plate 36 having a row of alternating, lengthwise extending recesses 54 and projections 56.
- the upperv die plate 34 having a row of alternating, lengthwise extending projections 52 and recesses 53 along its lower edge
- the lower die plate 36 having a row of alternating, lengthwise extending recesses 54 and projections 56.
- the upper and lower die plates of the stationary jaw assembly are further keyed to the upper and lower housing sections at their relatively adjacent ends.
- the wall sections 38 and 46 of the upper and lower housing sections are recessed along their relatively adjacent ends so as to provide a reentrant groove 57 which extends across the width of the crusher housing between the upper and lower section thereof.
- the projections 52 of the upper die plate are extended rearwardly to form lugs 58 which in the assembled condition of the stationary jaw assembly are seated in the groove 57, between the upper and lower side walls thereof which extend at right angles to the faces of the coplanar wall portions 38 and 46.
- Engagement of the lugs 58 with the upper and lower side walls of the grooves 57 keys the upper die plate 34 vertically on the crusher housing.
- the projections 56 of the lower die plate 36 are extended rearwardly to form lugs 59 which in the assembled condition of the stationary jaw assembly alternate with the lugs 58 in the groove 57, the lugs 59 like the lugs 58 being fitted between the upper and lower side walls of the groove 57 so as to key the lower die plate vertically on the crusher housing.
- a rock 61 is shown between the stationary die assembly 6 and the swinging die assembly 4 in a position which causes oppositely directed side loads to become effective upon the stationary and swingable jaw assemblies when the swinging jaw assembly is forced toward the stationary jaw assembly by rotation of the eccentric shaft 5 and conjoint action of the toggle plate 11.
- a lateral thrust component T of the crushing force C tends to shift one of the die plates of the swinging jaw assembly 4 to the right on the pitman 7, and a corresponding lateral thrust component T, ofthe crushing force C tends to shift the opposite die plate of the stationary jaw assembly to the left on the stationary housing wall assembly 38, 46.
- a pair of retaining wedges 63 engage a beveled upper edge of the swinging die plate 13, and an adjacent beveled edge of a conventional hub guard 64, the wedges being held in place by bolts 66 and associated nuts 67.
- the lower edge of the lower die plate 14 is beveled to match a correspondingly beveled retaining ledge 68 at the lower end of the pitman 7.
- said projections of said die plates having lug portions seated in said groove between said wall portions of said upper and lower housing sections.
