Description
Technical field
The utility model relates to a kind of technical field of jaw crusher, and a kind of anodontia tooth plate of more specifically saying so is broken secondary.
Background technology
A principal organ in the jaw crushing machine equipment is a crusher chamber, and it is made up of two tooth plates (also claiming jaw or dental lamina).The prior art jaw crusher all is not select solid flat board for use usually, 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 big; The 2nd, utilize odontoid realize " split broken, folding is broken, squeeze broken " etc. multiple broken mode of work-doing (when the tooth peak pushes material: material will be split along tip pressure effect be called split broken; Material stress effect by bending and by jackknifing be called the folding broken; Material is called crowded broken because of facial action of compressive stress by squeeze crack), 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 all is 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, closely is tending towards dull and stereotyped like this.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 all is to carry out crushing operation under the dull and stereotyped state in Asia, and " profile of tooth " decays along with the profile of tooth wearing and tearing in crushing operation, and practical function is limited.
The applicant once invented and had declared a kind of multi-functional broken secondary utility model patent of reviewing one's lessons by oneself profile of tooth, application number is 201110064975.7, it includes fixed tooth plate and swing tooth plate, include substrate on fixed tooth plate and the swing tooth plate, substrate is provided with tooth peak and tooth paddy, the broken secondary fixed tooth plate and the relative interlaced arrangement with tooth paddy in tooth peak of swing tooth plate; Be provided with the through hole that runs through substrate in the described tooth paddy, these through holes are row with respect to the tooth peak length direction on the offside tooth plate and arrange.Can eliminate inferior dull and stereotyped broken state to a certain extent though review one's lessons by oneself profile of tooth, because the existence of profile of tooth, the snap-in force of tooth paddy and tooth peak relative engagement still is inadequate (have snap-in force owing to tooth paddy place has through hole to exist, but place, tooth peak not having).
The utility model content
The purpose of this utility model is to overcome the little defective of the broken snap-in force of prior art, provides a kind of anodontia tooth plate simple in structure, that cost is low, that have bigger broken snap-in force broken secondary.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of anodontia tooth plate is broken secondary, comprises that a pair of face-off forms the tooth plate of crusher chamber, it is characterized in that described tooth plate is dull and stereotyped, is arranged to the cellular mesh structure on the flat board.
Core technology of the present utility model is: broken through the traditional approach that the prior art tooth plate is provided with profile of tooth, initiative a kind of anodontia tooth plate of having designed (is a mesh network pore structure tooth plate, down together), replace tooth Shape Design with being the netted design of honeycomb, increase the power of frustrating and shearing between two tooth plates, optimized the Cracking Mechanism (change with the crushing is that main transformer is that shearing-crushing is main) of jaw crusher.
Anodontia tooth plate has not only possessed the broken function that has the tooth tooth plate to be had, and compare more superior.
Facts have proved that " the tooth tooth plate is arranged " wants much superior than the crushing performance of " solid surface plate ", so jaw crusher is just come in a group with the tooth tooth plate is arranged from being born.Have the tooth tooth plate have " split broken, folding is broken, squeeze broken " etc. multiple broken function, but all bring into play insufficiently, and anodontia tooth plate of the present utility model has exactly been strengthened these functions.
1. split broken function: (material is in and has cusped edge, cultrate metal surface and when being squeezed, can form the crack behind cusped edge or the blade wedging material, and material inside just produces tensile stress, and when it reached the hot strength limit, then material was split and broken).In broken secondary " V " type crusher chamber upper end that the tooth tooth plate is arranged, material size is bigger, and the effect of space width can be ignored, and is exactly that crown is being split broken effect during broken work, and this is that one of important function that the tooth tooth plate played is arranged.Since the vertical bar shaped flute profile under the prior art will consideration itself intensity, profile of tooth is too narrow easily bursts apart, therefore the profile of tooth width can not be too narrow, basically 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, and splits just decay gradually of broken effect, only there was 1/5～1/3 time to have obvious profile of tooth playing a role, and the most of the time all under the dull and stereotyped state in Asia, work (in fact the tooth tooth plate is arranged mainly is for basic broken function with crushing).And anodontia tooth plate does not have outstanding very dark vertical bar profile of tooth, and it strengthens self intensity by the mesh network pore structure, and its netted muscle is than narrow many of profile of tooth, thus cancellated split broken function ratio odontoid to produce effect manyly.Moreover network structure is set to through hole.This structure can not split broken function decay because of wearing and tearing make, and does not have inferior dull and stereotyped state to occur, and in the whole length of service of tooth plate, splits broken function and keeps maximization consistently.
2. roll over broken function: (material is on the side band metal fin at regular intervals, and by the fin of the staggered opposite side of face-off it is pushed, material will produce flexural deformation, when its bending stress reaches the bending stress strength degree, then by the fragmentation that fractures).Tooth plate owing to two face-offs in the broken pair of tooth tooth plate is arranged all is set to " tooth paddy " correspondence " tooth peak ", in " V " crusher chamber, the bottom, for size approach space width material (especially those the band needle-likes, the material of sheet), theoretically basically all rolling over broken mode fragmentation, but in fact since profile of tooth to wear and tear, roll over broken mode and can decay, act on also limited.
The mesh of two tooth plates of anodontia tooth plate face-off of the present utility model also is that the hole heart is to limit, hole interlaced arrangement, when size approaches the material of mesh size equally to roll over broken mode fragmentation, with the tooth tooth plate arranged compare, anodontia tooth plate does not have inferior dull and stereotyped the appearance, and rolling over broken effect can uniform maintenance maximization.
3. squeeze broken function: (when material size critical in a side tooth plate the tooth bar spacing or during the aperture, squeeze brokenly and will produce when being subjected to the offside extruding, just as squeezing toothpaste out of a tube, be extruded after sub-fraction can be stripped from extruded material edge, Here it is squeeze broken).Owing to there is the spur rack of tooth tooth plate to be up-narrow and down-wide structure, effectively squeeze broken effect seldom.Anodontia tooth plate is than there being the tooth tooth plate more to meet the condition of extruding, in " V " of anodontia tooth plate type crusher chamber, the bottom, only need mesh size with anodontia tooth plate be designed to the through hole that adapts with required broken finished product material size and design hopper at the tooth plate back side, then most of critical material can be by squeezing broken mode fragmentation, and allow material up to specification withdraw from crusher chamber in advance, avoid overcrushing and save power consumption.
In sum, the broken function of anodontia tooth plate of the present invention is more than there being the tooth tooth plate to have superiority.No matter split broken, folding is broken, or squeeze brokenly, it all is the function decay with the profile of tooth wearing and tearing that the tooth tooth plate is arranged under the prior art, act on limitedly, and splitting of anodontia tooth plate is broken, the folding is broken, crowded broken function is brought into play more fully.
Anodontia tooth plate of the present utility model also is than the superiority that tooth tooth plate maximum is arranged: it has realized frustrating fully, shearing-crushing.Frustrate and cut broken function: material is in staggered position, both sides, and the material side is subjected to the extruding of blade-like metal surface, frustrates just as file and cuts, and material produces at stressed place frustrates and cut stress intensity when reaching the limit of, and the material marginal portion is frustrated cuts and broken; The shearing-crushing function: material is in staggered position, both sides, is subjected to the positive extruding in blade-like metal surface, and just as scissor cut, when the shear stress intensity that material produces at stressed place reached the limit of, the material marginal portion was sheared and fragmentation.Though anodontia tooth plate is dull and stereotyped, but the network structure setting is arranged, in fact it frustrate cutter and scissors just as a secondary well combination, material with frustrate, the mode of cutting is broken, this is the most basic crumbling method under the broken side conditions of anodontia tooth plate, because the anti-shearing stress-strength ratio compressive stress intensity of material is much lower usually, more produce effect than being in the crushing fragmentation so be in the fragmentation of shearing under the mechanism.In a word, the present invention has changed the Cracking Mechanism of jaw crusher, makes it more superior.
Anodontia tooth plate of the present utility model has fully frustrates, breaks broken function, makes whole broken pair have big snap-in force function.This big snap-in force function is very favourable to fragmentation, and big snap-in force function embodiment is: 1. in " V " crusher chamber upper end, show as and grab that to sting (eating into) material very capable; 2. in whole shattering process, on one side material is broken, Yi Bian eat into toward the lower end, promptly material advances toward the discharge direction simultaneously along with fragmentation.Improved crushing efficiency.
Remarkable result of the present utility model is: make the prior art jaw crusher realize fully frustrating, breaking broken the time, make whole broken pair have big snap-in force function, thereby promoted the whole breaking capacity of jaw crusher effectively.
The beneficial effects of the utility model also have: (1) anodontia tooth plate of the present utility model does not exist profile of tooth to be worn to become inferior dull and stereotyped situation, whole mesh network pore structure tooth plate is an overall wear in the middle of wearing and tearing, the mesh network pore structure is remained the same from beginning to end, and crushing efficiency can not decayed.
(2) in the tooth plate manufacture process, carry out the quenching heat treatment operation, promptly to red-hot tooth plate immersion water, cool off fast, to reach the purpose of quench hardening heating.The present invention is provided with thickly dotted honeycomb hole group with tooth plate, increases the contact area of quenching tooth plate and water greatly, has improved the quenching degree in the quenching technical, thereby has strengthened hardness, wearability and the service life of tooth plate.
As preferably, this network structure is cellular.
Cellular is structure the most special in the network structure, and it not only has cancellated all characteristics, and its easier realization is at random, nondirectional shearing-crushing power, makes it have bigger broken snap-in force.In addition, in all network structures, forming under the situation of identical big small size, the hollow ratio of cellular formation bigger (hollow ratio=hollow area/gross area), it strengthened " split broken, folding is broken, squeeze broken " etc. broken function, more help improving crushing efficiency.
As preferably, the mesh hole heart on the side tooth plate and the limit, mesh hole on the offside tooth plate are staggered opposed.Under the staggered opposed situation in the mesh hole heart and limit, hole on two tooth plates of face-off, can more efficiently realization split, roll over, squeeze, frustrate function.
As preferably, described mesh is a through hole.
Through hole is the first-selected embodiment of the utility model mesh design, and wherein the specification material less than through-hole diameter can withdraw from fragmentation in advance, makes that fragmentation can be inexcessive.
As the alternative of such scheme, described mesh is a blind hole.
Reaching under the big key property prerequisite of the broken snap-in force of the utility model, blind hole also is the embodiment that can be used as the design of the utility model mesh.
