Description
Technical field
The present invention relates to jaw crusher technical field, more specifically say a kind of large snap-in force high-efficient jaw breaker that has.
Background technology
Yi Ge principal organ in jaw crushing machine equipment is crusher chamber, and it is comprised of two tooth plates (also claiming jaw or dental lamina).Prior art jaw crusher is all not select solid flat board conventionally, and the tooth plate of select tape dentation, reason has two: one, and the tooth plate of dentation and material contact-making surface are little, and broken pressure is large; The 2nd, utilize odontoid realize " split broken, roll over broken, squeeze broken " etc. multiple broken mode of work-doing (when tooth peak pushes material: material by the mode being split along tip pressure-acting be called split broken; Material by bending effect of stress and by the mode of jackknifing be called folding broken; Material because of facial action of compressive stress by the mode of squeeze crack be called squeeze broken), to improve crushing efficiency.
Because tooth plate is in the mill in order to guarantee that profile of tooth has enough intensity, profile of tooth is all the wide structure of the narrow base portion in top, and along with after broken process tooth top is worn gradually, tooth top broadens gradually like this, is closely tending towards dull and stereotyped.In fact in the whole length of service of tooth plate, only there is time of 1/5～1/3 to have obvious profile of tooth playing a role, and the most of the time is all to carry out crushing operation under the dull and stereotyped state in Asia, " profile of tooth " decays along with profile of tooth wearing and tearing in crushing operation, and practical function is limited.
The applicant once invented and had declared a kind of patent of invention of reviewing one's lessons by oneself the Multifunctional crushing pair of profile of tooth, application number is 201110064975.7, it comprises fixed tooth plate and swing tooth plate, on fixed tooth plate and swing tooth plate, include substrate, on substrate, be provided with tooth peak and tooth paddy, the tooth peak interlaced arrangement relative to tooth paddy of the fixed tooth plate of crushing pair and swing tooth plate; In described tooth paddy, be provided with the through hole that runs through substrate, these through holes are row with respect to the tooth peak length direction on offside tooth plate and arrange.Although review one's lessons by oneself profile of tooth, can eliminate to a certain extent sub-dull and stereotyped broken state, due to the existence of profile of tooth, the snap-in force of tooth paddy and tooth peak relative engagement or inadequate (because there is the existence of through hole at tooth paddy place, have snap-in force, place, tooth peak does not have).
Summary of the invention
The object of the invention is to overcome the little defect of the broken snap-in force of prior art, a kind of simple in structure, low-cost, high-efficient jaw breaker with larger broken snap-in force is provided.
In order to reach above object, the present invention is achieved through the following technical solutions: a kind of have a large snap-in force high-efficient jaw breaker, comprise frame, in frame, be provided with driving shaft, crushing pair, moving jaw and bracket, crushing pair comprises that a pair of face-off forms the tooth plate of crusher chamber, wherein a tooth plate is fixedly connected in frame, and another tooth plate is fixedly connected on moving jaw; Moving jaw upper end is articulated on driving shaft, and lower end is articulated on bracket; On driving shaft, be connected with drive; It is characterized in that, described tooth plate is dull and stereotyped, is arranged to mesh network pore structure on flat board.
Core technology of the present invention is: broken through the traditional approach that prior art tooth plate arranges profile of tooth, having designed in a creative way a kind of Toothless toothed plate (is mesh network pore structure tooth plate, lower same), with being the netted design of honeycomb, replace tooth Shape Design, increase the power of frustrating and shearing between two tooth plates, optimized the Cracking Mechanism (change to crush is that master is that shearing-crushing is main) of jaw crusher.
Toothless toothed plate has not only possessed the crushing function that has tooth tooth plate to have, and compare more superior.
Facts have proved, " having tooth tooth plate " is more more advantageous than the crushing performance of " solid surface plate ", so jaw crusher is just come in a group with there being tooth tooth plate from being born.Have tooth tooth plate have " split broken, roll over broken, squeeze broken " etc. multiple crushing function, but all bring into play insufficiently, and Toothless toothed plate of the present invention has exactly been strengthened these functions.
1. split broken function: (when material is in cusped edge, cultrate metal surface and is squeezed, after cusped edge or blade wedging material, can form crack, material inside just produces tensile stress, and when it reaches the hot strength limit, material is split and fragmentation).In crushing pair " V " the type crusher chamber upper end that has tooth tooth plate, material size is larger, and the effect of space width can be ignored, and during broken work, is exactly that crown is being split broken effect, and this is to have one of important function that tooth tooth plate plays.Due to the vertical bar shaped flute profile under prior art will consideration itself intensity, profile of tooth is too narrow easily bursts apart, therefore profile of tooth width can not be too narrow, substantially adopt up-narrow and down-wide structure to increase flute profile intensity, but along with profile of tooth is worn, the flank of tooth progressively broadens, split just decay gradually of broken effect, only there is 1/5～1/3 time to have obvious profile of tooth playing a role, and the most of the time all works under the dull and stereotyped state in Asia (in fact having tooth tooth plate is mainly to crush as basic crushing function).And Toothless toothed plate does not have outstanding very dark vertical bar profile of tooth, it is by mesh network pore structure strengthening self intensity, and its netted muscle is than narrow many of profile of tooth, and so that cancellated, splits broken function ratio odontoid will produce effect manyly.Moreover network structure is set to through hole, this structure can not have sub-dull and stereotyped state to occur because wearing and tearing make to split broken function decay, in the whole length of service of tooth plate, splits broken function and keeps consistently maximizing.
2. the broken function of folding: (material is on side band metal fin at regular intervals, and by the fin of the staggered opposite side that stands facing each other, it is pushed, material will produce flexural deformation, when its bending stress reaches bending stress strength degree, by the fragmentation that fractures).Tooth plate due to two face-offs in having tooth toothed plate crushing pair is to be all set to " tooth paddy " correspondence " tooth peak ", in " V " crusher chamber, bottom, for size close to the material of space width (those band needle-likes especially, the material of sheet), theoretically substantially all to roll over broken mode fragmentation, but in fact because profile of tooth will be worn and torn, roll over broken mode and can be decayed, act on also limited.
The mesh of two tooth plates of Toothless toothed plate face-off of the present invention is Xin Duikong limit, hole interlaced arrangement, when size close to the material of mesh size equally to roll over broken mode fragmentation, with have tooth tooth plate and compare, Toothless toothed plate does not have sub-dull and stereotyped state to occur, rolls over broken effect and can keep consistently maximizing.
3. squeeze broken function: (when the critical tooth bar spacing in a side tooth plate of material size or aperture, be subject to offside extruding and will produce and squeeze brokenly, just as squeezing toothpaste out of a tube, after extruded material edge can be stripped from sub-fraction, extrude, Here it is squeeze broken).Owing to there being the spur rack of tooth tooth plate to be up-narrow and down-wide structure, so effectively squeeze broken effect seldom.Toothless toothed plate is than there being tooth tooth plate more to meet the condition of extruding, in " V " of Toothless toothed plate type crusher chamber, bottom, only the mesh size of Toothless toothed plate need be designed to the through hole adapting with required broken finished product material size and design hopper at the tooth plate back side, most of critical material can be broken by squeezing broken mode, and allow material up to specification exit in advance crusher chamber, avoid overcrushing to save power consumption.
In sum, the crushing function of Toothless toothed plate of the present invention is more than there being tooth tooth plate to have superiority.No matter split broken, roll over broken or squeeze brokenly, under prior art, having tooth tooth plate is all the function decay with profile of tooth wearing and tearing, act on limited, and splitting of Toothless toothed plate broken, roll over broken, squeeze broken Function and obtain more abundant.
Toothless toothed plate of the present invention with have tooth tooth plate to compare maximum superiority to be also: it has been realized fully and having frustrated, shearing-crushing.Frustrate and cut crushing function: material is staggered position in both sides, material side is subject to the extruding of blade-like metal surface, just as file, frustrates and cuts, and material produces at stressed place frustrates and cut stress intensity while reaching the limit of, and material marginal portion is frustrated cuts and broken; Shearing crushing function: material is staggered position in both sides, is subject to the positive extruding in blade-like metal surface, and just as scissor cut, when the Shear stress strength that material produces at stressed place reaches the limit of, material marginal portion is sheared and fragmentation.Although Toothless toothed plate is dull and stereotyped, but there is network structure setting, in fact it frustrate cutter and scissors just as a secondary well combination, material frustrating, the mode of cutting is broken, this is the most basic crumbling method under Toothless toothed plate crushing pair condition, because the anti-shearing stress-strength ratio compressive stress intensity of common material is much lower, so the fragmentation in shearing under mechanism more produces effect than the fragmentation in crushing under mechanism.In a word, the present invention has changed the Cracking Mechanism of jaw crusher, makes it more superior.
Toothless toothed plate of the present invention has fully frustrates, cuts crushing function, makes whole crushing pair have large snap-in force function.This large snap-in force function is very favourable to fragmentation, and large snap-in force function embodiment is: 1. in " V " crusher chamber upper end, show as and grab and sting (eat into) material very capable; 2. in whole shattering process, material be broken, and meanwhile toward lower end, eat into, material is along with broken and advance toward discharge direction simultaneously.Improved crushing efficiency.
Remarkable result of the present invention is: jaw crusher under prior art fully realized frustrate, when cutting crushing function, made whole crushing pair have large snap-in force function, thereby effectively promoted the Integral-crushing ability of jaw crusher.
Beneficial effect of the present invention also has: (1) Toothless toothed plate of the present invention does not exist profile of tooth to be worn and is sub-dull and stereotyped situation, whole mesh network pore structure tooth plate is overall wear in the middle of wearing and tearing, mesh network pore structure consistently, can not decay by crushing efficiency.
(2), in tooth plate manufacture process, carry out quenching heat treatment operation, heating, to red-hot tooth plate, be immersed in the water cooling fast, to reach the object of quench hardening.The present invention is provided with thickly dotted honeycomb hole group by tooth plate, greatly increases the contact area of quenching tooth plate and water, has improved the quenching degree in quenching technical, thereby has strengthened hardness, wearability and the service life of tooth plate.
Cellular is structure the most special in network structure, and it not only has cancellated all characteristics, and it more easily realizes random, nondirectional shearing-crushing power, makes it have larger broken snap-in force.In addition, in all network structures, in the situation that forming formed objects area, the hollow ratio of cellular formation is large (hollow ratio=hollow area/gross area) more, it has strengthened " split broken, roll over broken, squeeze broken " etc. crushing function, be more conducive to improve crushing efficiency.
As preferably, the mesh hole heart on a side tooth plate and the limit, mesh hole on offside tooth plate are staggered opposed.On two tooth plates of face-off, in the staggered opposed situation in Xin Yukong limit, mesh hole, can more efficiently realization split, roll over, squeeze, frustrate function.
As preferably, described mesh is through hole.
Through hole is the first-selected embodiment of mesh of the present invention design, and the specification material that is wherein less than through-hole diameter can exit fragmentation in advance, makes the fragmentation can be inexcessive.
As the alternative of such scheme, described mesh is blind hole.
Reaching under the key property prerequisite that the broken snap-in force of the present invention is large, blind hole is also the embodiment that can be used as mesh design of the present invention.
