Description
Technical field
The utility model relates to the jaw crusher field; A kind of back of saying so more specifically is the high quality of fit jaw of physical plane.
Background technology
Jaw is also claimed jaw, is the vitals in the jaw crusher, and its Design and Features directly influences the broken overall performance of jaw.
See that from side-looking jaw structure (see figure 1) can be divided three parts: 1. tooth portion, 2. base portion and 3. backs.Dorsal area under the prior art all is matrix pattern frame structure (or groove structure), and the disintegrating machine of prior art and the mating surface of jaw also are the matrix pattern frame structures.Facts have proved that such design is obviously unreasonable:
1. processed by high hardness material because of jaw, and the frame and the moving jaw that cooperate with it are the common iron manufacturing, the hardness great disparity is big.The hardness of great disparity and low precision cooperate makes field cabinet frame body strong impaction, extruding and the filing frame in shattering process on the jaw back, in imbedding the frame pedestal, destroy the frame plane, so that frame shortens dramatically service life.
2. the jaw material character is hard and crisp; Its rigidity intensity is except relevant with itself intensity, and also relevant with the precision that cooperates with frame, jaw matrix pattern support body has destroyed its quality of fit; Increase the probability of jaw fracture greatly, the service life of having reduced jaw.
3. jaw is a consumable accessory; Often will change, the manufacturing of matrix pattern support body has error, and field, the back cabinet frame body difference that different manufacturers is produced is just bigger; The different different parts of matrix pattern support body on the frame face be strong impaction, extruding and filing frame constantly; Be the cooperating of jaw and frame unusual cakes with moulded designs does not have quality of fit to say at all, influences the crushing efficiency and the life-span of disintegrating machine.
The prior art jaw is designed to field cabinet frame body structure with the back, is big technological mistaken ideas:
1. seemingly follow the theory of mechanics of " part of two cooperatively interact (large tracts of land contacts); reduce contact-making surface and can improve quality of fit "; In fact having ignored jaw is hard material; Reduce contact area here and on the contrary frame is made powerful extruding and filing, the precision that heavy damage cooperates with the frame pedestal.The precision that both cooperate is not to improve but greatly reduction.
2. unilaterally think that the back do not participate in fragmentation directly, empty its volume and can save material.The fact is on the contrary again, and field cabinet frame body structure is invaded and cut frame, has not considered that at dorsal area the space being set can increase bump to frame (contact area reduces, and pressure increases) and extruding force, reduces the frame life-span and be the factor of bigger waste material.
Changing an angle says; As the front to jaw " is moved " in " space " in the cabinet frame structure of jaw field and " material "; Be tooth portion zone,, strengthen the tooth peak to deepen tooth paddy; Then can under the prerequisite of same volume, homogenous quantities, strengthen dentalation formula jaw greatly, improve crushing efficiency and increase the service life.
The utility model content
The purpose of the utility model is to overcome above-mentioned drawback, provides a kind of preventing closely not produce bump, push and imbed because of the jaw back cooperates with frame, thereby the back that prolongs frame service life is the high quality of fit jaw of physical plane.
For reaching above purpose, the utility model is realized through following technical scheme: a kind of back is the high quality of fit jaw of physical plane, comprises tooth portion, base portion and back, it is characterized in that, said back is the physical plane.
Said tooth portion is the panel with tooth paddy and tooth peak, is provided with evenly spaced crosspiece in the tooth paddy.
The remarkable architectural feature of the utility model is: the back of prior art jaw being changed " matrix pattern support body " structure is the physical plane structure.
The remarkable function of the utility model is: jaw and frame pedestal are closely cooperated, prevent closely not produce bump, push and imbed because of the jaw back cooperates with frame, thereby prolong frame service life.
Below we can be from the analysis of four kinds of fit forms of jaw back and frame pedestal the more science and the necessity of profound understanding the utility model usefulness.
1, match with the large-area plane of frame pedestal in large-area plane, jaw back.This cooperation is unfavorable for even contact, and both are closely cooperated, and does not meet Principle of Mechanical Designing.
2, the jaw back is that the small size of field cabinet frame body matches with the large-area plane of frame pedestal, and promptly the small size of hard material cooperates with the large tracts of land of soft material.It is cost to imbed the frame pedestal that this cooperation can make first jaw through break-in, reach the higher cooperation of precision, but jaw is an attrition component; Turnover rate is high; Make at the back has error, and the difference of the field cabinet frame body that different manufacturers is made is bigger, begins from second jaw changing; Just be difficult to cooperate precision, do not reach the purpose that closely cooperates.
3, jaw back and frame pedestal are field cabinet frame body structure, and promptly small size cooperates (situation under the prior art that Here it is) with small size.This cooperation not necessarily overlaps because of two small sizes just, and a side of hard is imbedded a soft side more easily, and fiting effect is poorer, and wearing and tearing are more severe.This is the poorest a kind of in four kinds of fit forms, and the prior art jaw just belongs to this situation.
4, the jaw back is that large tracts of land and the frame pedestal on plane are that the small size of field cabinet frame body cooperates.This cooperation has the following advantages: (1) jaw back surface is big and flat, does not have the phenomenon of imbedding the frame pedestal; (2) both cooperate closely, and wearing and tearing are slight; (3) this fit system can also be eliminated because of making, install and using the out-of-flatness error of bringing, and makes cooperation use tightr and tightr; (4) versatility of jaw is very high.This is best a kind of in four kinds of fit forms, just the new construction jaw that provides of the utility model.
The core technology of the utility model is: change the back design of jaw field cabinet frame body structure into solid planar structure, " space " and " material " that the back will be set simultaneously " moved " to the jaw front, deepens tooth paddy, strengthens the tooth peak; The plane large tracts of land at its back and the small size of frame seat field cabinet frame body structure are closely cooperated; Stop the frame pedestal is imbedded at the jaw back because of bump, extruding and filing phenomenon; Strengthen the jaw crushing function; Improve the jaw versatility, prolong frame service life, thereby improve crushing efficiency and economic benefit.
The utility model also has following beneficial effect except that above-mentioned remarkable function:
The utility model jaw have eliminate voluntarily because of make, install and use in bring the function of error, quality of fit is used higher and higher.
2. the back of the utility model jaw is the cutting of free of discontinuities property when processing plane, and processing technology is helped very much.
3. the large tracts of land with hard material matches with the small size of soft material, can not produce wearing and tearing, makes the frame long service life.
As preferably, said crosspiece height is lower than the tooth peak heights.This scheme makes jaw have tooth-shape structure, helps realizing the superior Cracking Mechanism of " split, roll over and squeeze ".
As preferably, height such as said crosspiece and tooth peak.Because the utlity model has and review one's lessons by oneself the profile of tooth function, crosspiece and tooth peak are set to the height such as grade, in shattering process, grind " tooth " shape then more certainly, the chamber type is more accurate like this.
As the alternative of such scheme, said tooth portion is the panel with mesh; Said mesh is shaped as hexagon, ellipse, rectangle or rhombus.Netted jaw is the novel jaw that the applicant innovates, and uses the utility model technology again and just has more superiority.
